the Commission’s Rules of Practice, the
‘‘burden to demonstrate that a proposed
rule change is consistent with the
Exchange Act and the rules and
regulations issued thereunder . . . is on
the self-regulatory organization [‘SRO’]
that proposed the rule change.’’ 28 The
description of a proposed rule change,
its purpose and operation, its effect, and
a legal analysis of its consistency with
applicable requirements must all be
sufficiently detailed and specific to
support an affirmative Commission
finding, and any failure of an SRO to
provide this information may result in
the Commission not having a sufficient
basis to make an affirmative finding that
a proposed rule change is consistent
with the Exchange Act and the
applicable rules and regulations.29 The
Commission concludes that, because
NYSE Arca has not demonstrated that
its proposal is designed to prevent
fraudulent and manipulative acts and
practices or to protect investors and the
public interest, the Exchange has not
met its burden to demonstrate that its
proposal is consistent with Section
6(b)(5) of the Exchange Act.30 For this
reason, the Commission must
disapprove the proposal.
IV. Conclusion

For the reasons set forth above, the
Commission does not find, pursuant to
Section 19(b)(2) of the Exchange Act,31
that the proposed rule change is
consistent with the requirements of the
Exchange Act and the rules and
regulations thereunder applicable to a
national securities exchange, and in
particular, with Section 6(b)(5) of the
Exchange Act.32
It is therefore ordered, pursuant to
Section 19(b)(2) of the Exchange Act,
that proposed rule change SR–

30 In disapproving this proposed rule change, the
Commission has considered the proposed rule’s
impact on efficiency, competition, and capital
formation. See 15 U.S.C. 78c(f). Although the
commenter (see SIFMA Letter, supra note 14, at 4)
asserts that the current Beneficial Holders Rule puts
newer and smaller sponsors at an unnecessary
disadvantage to larger sponsors having the
enterprise-wide scale and distribution reach to
gather assets in the months after launch, neither the
commenter nor the Exchange has provided data to
support this conclusion.

Exchange Commission (‘‘Commission’’)
the proposed rule changes described in
Items I, II and III below, which Items
have been prepared by ICE Clear
Europe. The Commission is publishing

ICE Clear Europe is proposing to
amend the Documents and institute the
new Parameters Procedures principally
to describe more fully certain existing
Clearing House practices, as discussed
herein. ICE Clear Europe is also
proposing to make certain
enhancements to CDS stress testing,
specifically to incorporate the impact of
the COVID–19 pandemic into its stress
testing framework.
CDS End of Day Price Discovery Policy
The amendments to this policy would
generally clarify the process to
determine prices for a particular
instrument when fewer than three
Clearing Members have open interest in
that instrument, in order to provide
more reliable pricing in that scenario.
The amendments would also make
minor terminology updates to conform
uses of defined terms, correctly
reference various ICE Clear Europe
personnel and operations and make
similar typographical corrections
throughout the document and add a
new table.
Currently, the CDS End of Day Price
Discovery Policy states that if fewer
than three CDS Clearing Members have
cleared open interest in an instrument,
ICE Clear Europe may require all CDS
Clearing Members to provide a price
submission for that instrument. ICE
Clear Europe proposes to supplement
this concept to provide more flexibility
to ensure enough submissions to enable
effective determination of reliable endof-day prices and thereby facilitate an
accurate and stable variation margin
process. Specifically, the amendments
are designed to produce more reliable
prices by increasing the probability of
receiving multiple submissions. As
amended, the policy would state that
ICE Clear Europe believes that tradeable
quotes submitted by CDS Clearing
Members are the preferred source of
data and should be used where possible
and reliable, meaning where there is
more than one CDS Clearing Member
with which the quote could be crossed.
Where there are not enough CDS
Clearing Members to enable tradeable
quotes (i.e., quotes at which a member
would transact) to be crossed with more
than one CDS Clearing Member (i.e.,
fewer than three CDS Clearing Members
E:\FR\FM\08MRN1.SGM
08MRN1
jbell on DSKJLSW7X2PROD with NOTICES
13418
Federal Register / Vol. 86, No. 43 / Monday, March 8, 2021 / Notices
with open interest in the relevant
instrument), then ICE Clear Europe
would switch to rely on indicative
quotes and would require these from all
CDS Clearing Members. (For this
purpose, an indicative quote is a
reasonable estimate of the market price
but does not necessarily reflect a price
at which the member would transact.)
When requesting indicative quotes in
this manner, ICE Clear Europe would
not require CDS Clearing Members to
enter into firm-trades in these
instruments. The minimum number of
three CDS Clearing Members, below
which indicative quotes would be used,
would be subject to ongoing review by
ICE Clear Europe as to whether this is
the appropriate threshold given market
circumstances.
A new Table 4 showing an example
of an assignment of index risk factors to
market proxy groups would be added
pursuant to the amendments relating to
end-of-day bid-offer widths (‘‘EOD
BOWs’’) for index instruments. The new
table does not reflect a change in
practice and is intended for clarity. The
table would show the index risk factors
for each of the CDX and iTraxx market
proxy groups. A reference to Table 2 in
the EOD BOWs section would be
updated to Table 4. Existing references
to Tables 4 through 7 would be
respectively updated to Tables 5
through 8.
In the governance section addressing
material changes to the EOD price
discovery methodology, spread-to-price
conversion determinants or parameters,
the amendments would clarify that
review would be performed by the TAG
(instead of the TAC) and the Product
Risk Committee (instead of the Risk
Committee). This amendment is
intended to reflect current practice.
Numerous minor typographical and
similar updates would be made
throughout the CDS End of Day Price
Discovery Policy. For example, the term
‘‘Clearing Participant’’ would be
updated to ‘‘Clearing Member’’, ‘‘CP’’
would be updated to ‘‘CM’’ and
‘‘Trading Advisory Committee’’ (or
‘‘TAC’’) would be updated to ‘‘Trading
Advisory Group’’ (or ‘‘TAG’’), to be
consistent with terminology used in the
Rules and other ICE Clear Europe
documentation. The statement that the
trading desks at each self-clearing
member (‘‘SCM’’) would be required to
copy ICE Clear Europe on the intraday
quotes they provide market participants
via email would be updated to
requested to copy. Certain outdated
cross-references would be removed.
With respect to the red matters in the
escalation and notification protocol for
appetite metrics, the Board and
VerDate Sep<11>2014

Jkt 253001
Executive Risk Committee would be
notified immediately instead of as soon
as possible. Other minor clean-up
changes would also be made to improve
readability and clarity.
CDS Clearing Stress Testing Policy
ICE Clear Europe is proposing to add
new stress test scenarios to this policy
and to make certain other clarifications
and enhancements to the description of
the stress-testing methodology in order
to capture the large market moves
experienced during the COVID–19
pandemic, strengthen the CDS
discordant stress test scenarios and
better reflect the current governance
structure related to stress testing.
Purpose
The discussion of the purpose of Clear
House stress testing practices, including
as to how they are integrated into ICE
Clear Europe’s risk procedures and
governance structure, would be revised
to reflect the Clearing House’s current
governance framework, and specifically
to reference the Model Oversight
Committee (‘‘MOC’’) and to remove an
outdated reference to the Board Risk
Committee (‘‘BRC’’). The amendments
would also provide that any terms not
defined in the policy would be defined
in the ICE Clear Europe CDS Risk Policy
and the Rules, instead of only in the
Rules.
Methodology
The general methodology section of
the policy would be amended to add a
discussion of stress testing in the
context of wrong way risk. For this
purpose, positions in index risk factors
and single-name risk factors that exhibit
high levels of association with a
Clearing Member’s portfolio are
combined in a sub-portfolio, which is
subject to additional stress testing
analysis. The amendments to this
section do not reflect a change in
Clearing House practice but are
intended to better document existing
practice.
The amendments also revise the
governance process where a scenario or
portfolio in the standard set of stress
scenarios is no longer applicable, or is
superseded by new scenarios or
portfolios, and the Clearing Risk
Department wishes to retire or modify
the outdated scenario or portfolio. In
that case, the Clearing Risk Department
would conduct an analysis to determine
whether a change is significant, which
would be reviewed by the Risk
Oversight Department (‘‘ROD’’). The
Board, or its delegated committee,
would approve the significant
decommissioning of scenarios, while
PO 00000
Frm 00140
Fmt 4703
Sfmt 4703
the Model Oversight Committee
(‘‘MOC’’) would approve the
decommissioning of scenarios (if not
significant) or recommend the
decommissioning of scenarios to the
Board if deemed significant. The
amendment is intended largely to
formalize current practice, and also
reflect the role of the MOC under the
Clearing House’s Model Risk
Governance Framework (the ‘‘MRGF’’).
The existing description of the steps
that the Clearing Risk Department
would take in such a scenario (involving
approval by the relevant risk committee)
would be deleted. The amendments
would also clarify that if the Clearing
Risk Department wishes to add new
scenarios or portfolios, the MOC must
approve of the addition, but the Board’s
approval is not required. This is a
change from the current procedure,
under which it is sufficient to simply
inform the CDS Risk Committee.
Further, the amendments would also
state explicitly that in stress testing and
sensitivity testing, under the multiple
Clearing Member default scenario,
conditional uncollateralized loss-givedefaults (‘‘LGDs’’) resulting from
Clearing Member single-name positions
would also be explicitly incorporated.
This reflects current practice.
Various Changes
Various defined terms would be
updated throughout the document. The
CDS Product Risk Committee would be
referred to as the CDS PRC instead of
the CDS RC. Members or Clearing
Members would be referred to as CMs.
Throughout the document, references to
Initial Margin would be updated to IM
and references to Guaranty Fund would
be updated to GF.
Changes to Predefined Scenarios; New
COVID–19 Scenarios
The introductory description of the
predefined scenarios would be amended
to clarify that the scenarios reflect a
stress period of risk from 1 to 7 days
(referred to in the policy as ‘‘N’’-day
scenarios), taking into account the 5-day
margin period of risk used in the
existing margin methodology for house
accounts and the 7-day margin period of
risk used in the existing margin
methodology for client accounts. The
description of the magnitude of the base
‘‘FX Stress Scenario’’ would be
amended to state that it reflects the
greatest relevant N-day stress period
(instead of five days).
Overall, the changes to the stress
testing scenarios, other than the
addition of the new COVID–19
scenarios, are intended to more
thoroughly describe the stress test
E:\FR\FM\08MRN1.SGM
08MRN1
Federal Register / Vol. 86, No. 43 / Monday, March 8, 2021 / Notices
jbell on DSKJLSW7X2PROD with NOTICES
scenarios. The changes (including the
addition of the COVID–19 scenarios) are
not expected to result in any changes in
margin levels or other financial impact
on the Clearing House or Clearing
Members.
Extreme but Plausible Market Scenarios
The amendments would update the
description of the extreme but plausible
market scenarios. The description of the
2008/2009 credit crisis scenario would
be updated to state that the widening/
tightening credit crisis spread scenarios
are based on the greatest observed N-day
(instead of five-day) relative spread
increases/decreases expressed as
percentages. The amendments would
also clarify that the determination of the
exact stress period is defined by the
greatest observed spreads change of the
Most Actively Traded Instruments
(‘‘MATI’’) for each relevant subportfolio. The stress spread changes,
defined for each Index, corporate and
sovereign risk factor (‘‘RF’’), would be
extracted from the market history for the
MATI of the considered RF.
Amendments would also clarify that the
other three historically observed stress
test scenarios from the 2008/2009
period would be based specifically
around the period surrounding Lehman
Brothers’ default to capture the large
market moves of that period. These
amendments are intended to provide a
more thorough description of these
existing stress testing scenarios.
The description of the Western
European credit crisis scenarios would
similarly be clarified to state explicitly
that the scenarios replicate the stress
market moves resulting from the
concerns around the debt sustainability
of several Eurozone countries.
Widening/Tightening Western European
Credit Crisis Spread Scenarios would be
based on the greatest observed Nday
(instead of five-day) relative spread
increases/decreases (which would no
longer be restricted to the most actively
traded instruments). Amendments
would also clarify that the
determination of the exact stress period
would be defined by the greatest
observed spreads change of the MATI
for each sub-portfolio. The other three
historically observed stress test
scenarios would be based specifically
around the second quarter of 2010 to
capture the large market moves of that
period. The spread shocks would be
expressed in percentage for each RF.
These amendments are intended to
provide a more thorough description of
these existing stress testing scenarios.
The description of the Lehman
Brothers Default Price Change Scenario
would be expanded. The amendments
VerDate Sep<11>2014
19:05 Mar 05, 2021
Jkt 253001
would state that the scenario
magnitudes are defined for each RF
according to its sector classification and
time to maturity of the considered
instrument. The corresponding stress
test Opposite LB Default Price Change
Scenarios would be derived from the
Lehman Brothers scenarios by means of
multiplying the scenario result by a
negative factor to reflect the reduced
magnitudes of the observed price
increases during the considered period.
These amendments are intended to
provide a more thorough description of
these existing stress testing scenarios.
New COVID–19 Based Scenarios
Given that moves in both spreads and
prices were, generally, higher than other
observed extreme but plausible stress
test scenarios during the COVID–19
pandemic, ICE Clear Europe is
proposing to add the following
additional COVID–19 pandemic fear
scenarios based on stress market moves
experienced between February and
April 2020:
• The COVID–19 Widening/
Tightening Spread Scenarios, which
would be based on the greatest observed
N-day relative spread increases/
decreases during the period. The
determination of the exact stress period
would be defined by the greatest
observed N-day spread changes of the
MATI for each sub-portfolio; and
• The COVID–19 Price Decrease
Scenario would be defined in price
space to maintain the stress severity
during periods of low spread levels and
high prices, when the IM requirements
are expected to be lower. The scenario
would be based on the greatest observed
N-day relative price decreases during
the aforementioned period. The
determination of the exact stress period
would be defined by the greatest
observed N-day spread changes of the
MATI for each sub-portfolio. A
corresponding stress test COVID–19
Price Increase Scenario would be
derived from the price decrease scenario
by applying factors for Indices and SNs
to reflect the reduced magnitudes of the
observed price increases during the
considered period.
Discordant Scenarios
The scope of discordant spread
scenarios (for corporates and sovereigns)
would be clarified. Specifically, the
description of the corporate discordance
spread scenarios would reflect that such
scenarios are based specifically on
discordant moves along the major
European and North American 5Y onthe-run (OTR) indices. The amendments
would also state that the corporate SNs
and indices discordant spread scenarios,
PO 00000
Frm 00141
Fmt 4703
Sfmt 4703
13419
which reflect realizations when certain
indices or sub-indices for the EU region
and certain U.S. OTR indices exhibited
the greatest combined discordant
change, would be created and applied to
SNs and Indices. The amendments
would further update references to
indices used in stress scenarios and
state that other stress scenarios would
be based on discordant spread
realizations across European Indices.
The amendments would also note that
other stress scenarios would reflect
discordant spreads realizations among
geographical regions. These
amendments are intended to provide a
more thorough description of existing
stress testing scenarios.
Hypothetical Scenarios
With respect to hypothetical
scenarios, greater detail would be added
to clarify that the curve inverting spread
scenario is based on the largest
widening shock among the 2008/2009
Credit Crisis Widening and the Western
European Credit Crisis Widening for
each RF. Similarly, the curve steepening
spread scenario is based on the largest
tightening shock among the 2008/2009
Credit Crisis Tightening and Western
European Credit Crisis Tightening
scenarios.
New sectors and countries discordant
scenarios would also be added. These
scenarios would be designed to
reproduce discordant moves across
sectors and entities of different
countries, noting that the large price
moves in the oil benchmark products
(especially WTI negative prices) in the
first half of 2020 created asymmetric
shocks to the energy and financials
sectors compared to other sectors,
which would be reflected in the Energy
vs Other Sectors Discordant scenario.
The five-year spread shocks would be
estimated at sector level, and the
derivation of the shocks for the other
tenors would be based on the tenorspecific inverting and steepening
factors. The sector-specific shocks
would then be applied to all RFs within
the sector. The opposite stress scenario
would also be considered for
completeness. The spread shocks
estimated for the clearable Western
European Sovereigns would be applied
to the European corporate SNs for each
country. The opposite stress scenario
would also be considered for
completeness.
Another hypothetical scenario, the
forward-looking credit events scenarios,
would be updated to clarify that the
Clearing Member reference entity that
would be considered would be different
from the Clearing Member whose
portfolio is subject to the stress test.
E:\FR\FM\08MRN1.SGM
08MRN1
13420
Federal Register / Vol. 86, No. 43 / Monday, March 8, 2021 / Notices
They would also add that the reference
entity is assumed to enter in a state of
default and thus create Loss Given
Default (‘‘LGD’’) and that a reference
entity is selected that creates the largest
LGD exposure, rather than the greatest
one-year EOD spread level.
jbell on DSKJLSW7X2PROD with NOTICES
Extreme Market Scenarios
The amendments would clarify that
extreme steepening and extreme
inverting scenarios would be created
from crises steepening and crises
inverting scenarios by doubling the
shocks for inverting scenarios and
applying a factor to steepening
scenarios. The amendments would also
incorporate the new COVID–19
historical scenarios into the
determination of extreme scenarios,
similar to the calculation of extreme
scenarios based on the LB default
scenario.
With respect to the guaranty fund
(‘‘GF’’) scenarios, greater specificity
would be provided to clarify that the
stress test scenarios would be designed
to account for the occurrence of credit
events for two Clearing Member risk
factor groups (‘‘RFGs’’) and three nonClearing Member RFGs. The
amendments would also clarify that the
GF scenario considers an even more
extreme case in which five RFGs
undergo credit events (changing a
reference from single names to the more
accurate RFG). The chart setting out the
quantile ratios for the student t
distributions with different shape
parameters would be removed as
unnecessary.
The GF adequacy analysis would be
amended to state that as the number of
defaults of reference entities is one of
the major risks in the CDS clearing
service, the Clearing Risk Department
considers complementary extreme
scenarios where a combination of up to
five RFGs for up to five Clearing
Members would be assumed to default
before simulating spreads widening and
tightening on the non-defaulting entities
in order to fully deplete the GF. The
amendments would explain that the
scenario aims at providing estimates of
the level of protection achieved through
initial margin (‘‘IM’’) and GF in relation
to multiple defaults. This amendment is
intended to clarify the stress-testing
description but does not reflect a change
in current stress testing practice.
Portfolio Selection
The description of the process for
determination of sample portfolios for
stress testing would be updated to
reflect that ICE Clear Europe would
derive the portfolio from the currently
cleared portfolios by considering only
VerDate Sep<11>2014
19:05 Mar 05, 2021
Jkt 253001
positions in index RFs and sectors that
exhibit a high degree of association with
the considered Clearing Member, in
particular indices, sovereigns and
financials RFs (rather than considering
exactly the opposite positions from the
currently cleared portfolio). The
constructed sub-portfolios would be
subject to the stress test analysis with
the standard set of stress test scenarios.
The aim of the stress analysis with the
sample portfolios would be to provide
estimates to the potential exposure of
Clearing Members to RFs generating
general wrong way risk (‘‘WWR’’). The
current reference to special strategy
sample portfolios would be deleted, and
a new provision would address
application of stress testing scenarios to
expected future portfolios upon the
launch of new services and RFs. The
stress test analysis would be presented
and reviewed by the CDS Product Risk
Committee prior to launch of the new
RFs.
Interpretation and Review of StressTesting Results
The interpretation and review of the
stress-testing results section would be
amended to provide that enhancements
to stress scenarios would be discussed
and approved based on the governance
outlined in the MRGF. The amendments
would also clarify that the two greatest
affiliate groups’ (‘‘Cover-2’’)
uncollateralized stress loss associated
with scenarios characterized as extreme
but plausible market scenarios should
be covered by funded default resources
(excluding potential assessments). If
Cover-2 protection under these
scenarios is not achieved, additional
funds could be required to cover the
shortfall and enhancements to the
current risk methodology would be
considered. The amendments would
further provide that the Board and its
delegated committees (instead of the
CDS Risk Committee and Board Risk
Committee) would be provided with
information as to the stress test results
as necessary or appropriate to perform
their duties. The amendments are
intended to allow the Board the
flexibility to determine the appropriate
committees for review of stress testing.
Certain outdated statements would be
removed, including matters relating to
governance that are addressed in the
MRGF as well as outdated references to
certain examples or specific committees.
As discussed in the methodology
section above, any related deficiency
analysis and review would be
undertaken by the MOC instead of the
Executive Risk Committee, in
accordance with the procedures of the
MRGF. The stress testing report would
PO 00000
Frm 00142
Fmt 4703
Sfmt 4703
be presented to the CDS Product Risk
Committee instead of the CDS Risk
Committee during scheduled meetings
(instead of scheduled monthly
meetings).
The amendments would specifically
remove the following statements:
• The statement as to the stress
scenarios that lead to model review
include;
• the statement that the hypothetical
losses generated in response to stress
scenarios are compared to the available
margins on deposit and Guaranty Fund
contributions and if applicable, the ICE
Clear Europe contribution to the risk
waterfall and the funds available
through the one-time limited assessment
from each Clearing Member;
• the statement that ICE Clear Europe
is responsible for identifying in which
zone a particular stress test result falls;
and
• statements as to certain functions of
the Clearing Risk Department, Clearing
Risk senior management, ERC, CDS RC,
the BRC and the Board, which have
been replaced by the role of the MOC
and the other revised governance
arrangements discussed above.
Policy Governance and Reporting
The policy governance and reporting
section would be amended to remove
the requirement that the policy be
reviewed annually by the CDS Risk
Committee and only would require
review by the Board Risk Committee.
Material changes to the policy would be
discussed by the MOC (instead of the
ERC) and approved by the Board on the
advice of the CDS Product Risk
Committee and the Board Risk
Committee prior to implementation.
These amendments are intended to be
more consistent with other Clearing
House governance processes and
formalize existing arrangements to
ensure that appropriate bodies are
engaged in policy governance.
Appendix
The FX stress test scenario
amendments would reflect the greatest
N-day relative depreciation (instead of
five-day) and would remove the specific
dates. This is intended to be a
conforming change consistent with the
other amendments to use an N-day
period described above.
CDS Risk Policy
The amendments to this policy would
describe more fully the existing use of
the Clearing House’s Monte Carlo
(‘‘MC’’) simulation approach in the
context of establishing initial margin
and GF requirements. The amendments
would also generally clarify the use and
E:\FR\FM\08MRN1.SGM
08MRN1
jbell on DSKJLSW7X2PROD with NOTICES
Federal Register / Vol. 86, No. 43 / Monday, March 8, 2021 / Notices
source of intraday prices and make
other drafting improvements and
clarifications, including through
revising certain descriptions and
providing certain defined terms. The
amendments simplify certain cross
references to the CDS Risk Model
Description throughout the policy by
removing unnecessary section
references (to facilitate keeping the CDS
Risk Policy up to date). In general, the
amendments are intended to provide a
clearer explanation of the Clearing
House’s methodology for IM and GF
requirements and are not intended to
materially change the methodology or to
change the levels of IM and GF
requirements.
With respect to IM, the amendments
would clarify the description of the IM
methodology by stating that the risk
protection measure is based on using a
combined approach featuring a stressbased spread response Value-at-Risk
(‘‘VaR’’) measure and a Monte Carlo
(‘‘MC’’) simulation spread response VaR
measure. They would also add that
model performance would be monitored
through stress testing and sensitivity
analyses. The amendments are intended
to more clearly reflect existing practices,
and would not change the IM
methodology.
With respect to the spread response
requirements description, the
amendments would provide greater
clarity that the spread response risk
requirement that captures credit spread
fluctuations is a stress-based spread
response that computes Profit/Loss (‘‘P/
L’’) distributions from a set of simulated
hypothetical (forward looking) credit
spreads scenarios.
The description of the stress-based
spread response scenarios would be
modified by rewording the introduction
to improve readability and to clarify the
applicable benchmark tenors estimated
for all the Risk Sub-factors, replacing
certain outdated references to tenors.
The amendments are intended to reflect
and more clearly describe current
practices.
A new section would be added to
describe in more detail the Monte Carlo
simulation approach currently used by
the Clearing House. The amendments
would provide that in this approach,
ICE Clear Europe generates spread
scenarios by means of student-t copulas
to connect the univariate distributions
that describe spread fluctuations. The
student-t copulas reflect historical
estimates of Kendall t correlation
coefficients to simulate spread logreturns.
The simulated copula scenarios are
used to arrive at hypothetical spread
levels by means of estimated univariate
VerDate Sep<11>2014
19:05 Mar 05, 2021
Jkt 253001
spread log-return distributions. Each
instrument would be repriced at the
simulated spread levels to generate a
scenario instrument P/L based on postindex decomposition positions. For
each scenario, instrument P/Ls would
be aggregated according to pre-defined
RFs and sub-portfolio position sets in
order to obtain RF and sub-portfolio P/
Ls.
These distributions would be used to
estimate the RF and sub-portfolio 99.5%
VaR measures at a chosen risk horizon.
The portfolio level integrated Spread
Response would be estimated as a
weighted sum of RF and sub-portfolio
99.5% VaR measures.
The description of the antiprocyclicality considerations would be
updated to provide that the stress price
changes would be derived from the
price-based extreme but plausible stress
test scenarios under the revised CDS
Stress Testing Policy, as described
above, instead of only from the market
behavior during and after the Lehman
Brothers default period.
Throughout the policy, references to
the risk department would also be
updated to the Clearing Risk
Department.
The amendments also provide that the
Clearing Risk Department may
recommend margin methodology
changes based on the governance
procedures outlined in the MRGF,
consistent with the requirements of that
framework. The amendments would
also note that in the event that ICE Clear
Europe is accepting sizable positions
through the weekly back-loading
process in the context of margin calls,
it will pre-collect IM and mark-tomarket changes, instead of just IM.
With respect to mark-to-market
margin (‘‘MTMM’’), the description
regarding the determination of cash
owing, the payment of MTMM, the
timing of margin calculations and the
making of MTMM calls would be
removed as unnecessary operational
detail. These matters are also generally
covered in the CDS Risk Policy and
Finance Procedures. Similarly, the
discussion of the requirements and
rights of a Clearing Member upon a
change in MTMM balance (i.e. to pay or
be credited cash) would be deleted as
unnecessary detail.
With respect to intra-day monitoring,
the amendments would provide that ICE
Clear Europe would ensure the quality
of the intraday prices by monitoring and
comparing the quotes received with the
intraday prices of the transactions
cleared at ICE CDS clearing houses. ICE
Clear Europe could also compare
intraday prices with those of another
third-party provider. The comparison
PO 00000
Frm 00143
Fmt 4703
Sfmt 4703
13421
process would be carried out before
issuing intraday margin calls. The
description of the intraday risk limit
calculation would be updated such that
it would be based on 40% of the total
IM requirements, with a minimum
amount corresponding to the minimum
GF contribution and would be capped at
a monetary amount reviewed in
conjunction with the ICE Clear Europe
senior management and the CDS
Product Risk Committee. The precise
monetary amount would be removed
from the policy to give the Clearing
House flexibility if it determined it was
appropriate to review and reconsider
this amount in the future in conjunction
with senior management and the BRC.
There is currently no plan to change the
existing EUR 100 million cap in
practice. The procedure for intra-day
margin calls would be further clarified
by removing a statement that where
there has been a 50% erosion of the
Intraday Risk Limit, the Risk
Department will investigate the matter.
In ICE Clear Europe’s view, a separate
step at the 50% erosion level is
unnecessary, as ICE Clear Europe will
not take any particular action at that
level. Once the erosion exceeds 50%,
the Clearing Risk Department is
required to inform the relevant CDS
Clearing Member that it may be subject
to an intraday margin call (and in so
doing the Clearing Risk Department will
make any necessary investigations of the
matter).
The statement that the Risk
Management Department will notify the
ICE Clear Europe Treasury Department
of the ‘‘special’’ margin call would be
removed as an operational detail not
necessary for the policy. Generally, the
Clearing Risk Department sets the
margin level and would communicate it
to other departments in the ordinary
course, as it does for any change of
margin level.
With respect to the GF, the
amendments would update the drafting
of certain language (including the
reference to the ‘‘Cover 2’’ requirement)
to remove certain unnecessary detail.
With respect to related antiprocyclicality considerations, the
amendments would refer to the extreme
but plausible price-based stress test
scenarios described in the revised CDS
Clearing Stress Testing Policy, as
discussed above. Amendments would
also provide that the GF allocation
process is performed by the Clearing
Risk Department on a weekly basis
rather than every Thursday and based
on the previous business day’s close of
business positions rather than
Wednesday’s close of business
positions. The amendments would also
E:\FR\FM\08MRN1.SGM
08MRN1
13422
Federal Register / Vol. 86, No. 43 / Monday, March 8, 2021 / Notices
clarify that the requirement that a
portion of the GF be in USD is intended
to accommodate all USD-denominated
CDS contracts, not merely sovereign
CDS contracts . . . The current
numerical example of GF calls/
collection would be removed as
unnecessary.
With respect to back-testing, the
amendments provide if the model
calibration consistently demonstrates
exceptions outside of the coverage level,
the Clearing Risk Department would
review the models and recommend
revisions following the governance
procedures outlined in the MRGF.
Pursuant to the amendments, the
stress-testing section would add that the
historical data would account for
COVID–19 outbreak fear, consistent
with the changes to the CDS Stress
Testing Policy discussed above.
The amendments would update
certain terms throughout the document
as follows: ICE Clear Europe would be
referred to as ICEU; Member, member or
Clearing Member would generally be
updated to CM; Risk Model Description
would be updated to CDS Risk Model
Description; CDS Risk Committee would
be updated to CDS Product Risk
Committee; Risk Department, Risk
Management Department or Clearing
Risk department would be updated to
Clearing Risk Department; General
Wrong Way Risk would be referred to as
‘‘GWWR’’; Guaranty Fund would be
updated to GF, Specific Wrong Way
Risk would be abbreviated as SWWR;
Model Oversight Committee would be
given the acronym ‘‘MOC’’; the Model
Risk Governance Framework would be
given the acronym ‘‘MRGF’’; Initial
Margin would be updated to IM; Dollar

Testing Framework would be updated to
Policy; a Risk Oversight Committee
reference would be updated to ROC;
CDS Risk Product Committee and CDS
RC would be respectively updated to
CDS Product Risk Committee and CDS
PRC; and Risk Committee would be
updated to CDS PRC. Certain other
typographical corrections would be
made.

CDS Risk Model Description
This document was amended in May
2019 (the ‘‘2019 Amendments’’) and
additional amendments are currently
being proposed (the ‘‘Current
Amendments’’). As discussed below, the
Current Amendments would:
• Clarify the treatment of volatility
estimates for the Recovery Rate
Sensitivity Requirement (‘‘RRSR’’), risk
factor calibration and the raw data
cleansing process; and
VerDate Sep<11>2014
19:05 Mar 05, 2021
Jkt 253001
• add detail regarding the use of ICE
Clear Europe cleared volume in the
Concentration Charge threshold review.
• As discussed below, the 2019
Amendments:
• enhanced the calculation of the
WWR threshold;
• clarified the parameter estimation
of the recovery rate sensitivity
requirement;
• clarified the discussion around
model testing;
• added a section to explicitly refer to
the assumption around the use of the
same time series for IM and GF
distributions in the CDS Risk Model;
and provided that the interest rate
sensitivity requirement of the model
reflects a time horizon of five days for
house accounts and seven days for
client accounts.
With the exception of the changes to
the calculation of the WWR threshold,
the amendments are in the nature of
clarification and improving descriptions
of the Clearing House’s existing
methodology, and do not constitute a
change in the methodology. The
enhancement of the calculation of the
WWR threshold, as discussed below,
while a change from prior practice, is
expected to have an immaterial effect on
margin levels.
The 2019 Amendments
The following is a description in
further detail of the 2019 Amendments
to the CDS Risk Model.
Model Design and Development
The amendments updated the
description of the interest rate
sensitivity requirement component of
the IM model to add that the changes
captured in the discount default-free
terms structure used for pricing the
cleared instruments are over a certain
time horizon (five days for house
accounts and seven days for client
accounts). This amendment
documented existing practice.
Initial Margin Methodology
With respect to IM, the amendments
updated the loss given default risk
analysis to specify initial values of
certain parameters and to note that
certain parameters are reviewed by the
Risk Working Group on at least a
monthly basis.
With respect to the haircut applied as
part of the multi-currency portfolio
treatment methodology, the
amendments clarified that in order to
provide consistency and uniformity in
the parameters applied to the CDS risk
model, ICE Clear Europe adopted the
same (more conservative) haircut in line
with ICE Clear Credit LLC. This
PO 00000
Frm 00144
Fmt 4703
Sfmt 4703
amendment did not change existing
practice and was intended to strengthen
the IM methodology by documenting
existing practice.
Similarly, with respect to the foreign
exchange haircut applied to periodic
adjustments to the GF, the amendments
also clarified that in order to provide
consistency and uniformity in the
parameters applied to the CDS risk
model, ICE Clear Europe adopted the
same (more conservative) haircut in line
with ICE Clear Credit LLC. This
amendment also did not change existing
practice and was intended to strengthen
the IM methodology by documenting
existing practice.
Monte Carlo Implementation
Amendments were made to clarify
and simplify the overall description of
the Monte Carlo implementation. The
amendments were not intended to
reflect a change from current practice,
but rather provide a clearer description
of the existing implementation.
Specifically, ICE Clear Europe believes
that the revised description provides a
more practical, and less theoretical,
explanation of the Monte Carlo
implementation that will facilitate
replication and validation of the
implementation by third parties.
Among other clarifications, the
revised description states explicitly that
the final spread response requirement
would be the most conservative
requirement in the specified stressbased spread response equation, which
is consistent with current practice.
Certain subsections of the Monte Carlo
description, including those relating to
the discussion of matrix decomposition,
were deleted as unnecessary in light of
the description of the implemented
model. The amendments updated the
copula simulation description to
provide further detail as to the
determination and use of the linear
correlation matrix and construction of
student-t random variables and vectors
for the production of relevant scenarios.
The existing description of the
conditional block matrix simulation
framework and full matrix simulation
framework were revised to provide a
more simplified description of the twostep conditional simulation approach
that is currently used by the Clearing
House. A section describing copula
parameter estimation for purposes of
multivariate distribution was added
while the description of simulation for
standardized spread log returns was
removed as unnecessary. The model
parameters section was removed (with
relevant parameters being addressed in
the Parameters Procedures as discussed
below). Overall, these changes were
E:\FR\FM\08MRN1.SGM
08MRN1
Federal Register / Vol. 86, No. 43 / Monday, March 8, 2021 / Notices
jbell on DSKJLSW7X2PROD with NOTICES
intended to more clearly reflect the
current model, and would not represent
a change in methodology.
The Risk Measures section was
amended to reflect existing practice that
each cleared portfolio would be initially
split into sub-portfolios based on
common features in order to obtain risk
estimates reflective of the market
behavior and default management
practices. The definitions of the subportfolios and their respective risk
horizons would be periodically
reviewed by the ICE Clear Europe Risk
Management department and updated
upon consultation with the Product Risk
Committee.
More detail was provided with
respect to the use of simulated P/L
scenarios, combined with the postindex-decomposition positions related
to a given RF, to generate a currencyspecific RF P/L vector. Each risk factor
will be attributed to only one sub
portfolio and all instruments related to
a given risk factor would be
denominated in the same currency. The
multi-currency risk aggregation
approach will be applied to risk factors
within the European Corporate and U.S.
Corporate sub-portfolios denominated
in EUR and USD currencies,
respectively. A diagram would be added
to demonstrate a bivariate simulation
aspect of the risk aggregation approach.
This change was intended to document
existing practices.
The Monte Carlo Engine Setups
subsection and Conclusion subsection
to the Monte Carlo Implementation
section were deleted for improved
clarity as content relevant to the
implementation is addressed more
clearly in other sections, and the prior
description of the system or engine does
not, in ICE Clear Europe’s view, add
useful information beyond the other
aspects of model description.
Overall, these amendments generally
did not represent a change in current
operation of the MC component of the
risk model.
Time Series for IM and GF Distribution
A section explaining the existing use
of the same time series for IM and GF
distribution was added. The approach is
designed to be conservative and ensure
that the portfolio loss at 99.75%
quantile (used for GF determination)
would be always greater than 99.5%
quantile loss (used for IM
determination). The approach also
avoids unnecessary operational
complexity. The validity of the
assumption is monitored through the
stress test impact analysis. The
amendments were intended to
document existing practices and
VerDate Sep<11>2014
19:05 Mar 05, 2021
Jkt 253001
therefore were not expected to have a
material impact.
Current Amendments
The following is a description in
further detail of the Current
Amendments to the CDS Risk Model.
Initial Margin Methodology
The amendments clarify the source of
certain market risk transfer activity data
used in the concentration charge
threshold parameterization. The
amendments also update the loss
threshold calculation in the
determination of specific WWR and
general WWR (to be based on price
minus recovery rate as opposed to one
minus recovery rate). Although the
change makes the WWR calculation
more precise, the monetary impact on
margin requirements is expected to be
immaterial (and near zero). The
amendments would generally
strengthen the precision of the Initial
Margin methodology based upon
independent validation findings.
The amendments would provide
additional detail with respect to the
volatility floor value used in the IM
methodology. The amended description
would provide that the volatility floor is
estimated based on the average
overlapping five-day absolute change of
recovery rates (RRs) for a set of
defaulted names. The defaulted names
have a long time series of observed RRs
(i.e. more than a year) and comprise a
stress period of 2009–2012. The
Clearing Risk Department would be able
to review the estimated parameters in
case of the availability of sufficient long
time series of observed RRs. This is
consistent with existing practice and
intended to strengthen the IM
methodology by more clearly
documenting the practice.
The amendments would also clarify
that with respect to the concentration
charge threshold, the market risk
transfer activity data obtained from the
Depository Trust & Clearing Corporation
specifically contains both bilateral
positions and ICE cleared positions.
This is consistent with existing practice
and intended to strengthen the IM
methodology by more clearly
documenting the practice.
Anti-Procyclicality Measures
The amendments would modify the
approach to anti-procyclicality of spread
response requirements to be calibrated
based on historically observed extreme
but plausible stress test scenarios in
price space defined in the revised CDS
Stress Testing Policy, as discussed
above, which include various stress
scenarios including the Lehman
PO 00000
Frm 00145
Fmt 4703
Sfmt 4703
13423
Brothers’ default and COVID–19
outbreak. This broadens the current
anti-procyclicality approach, which is
based specifically on the Lehman
Brothers’ default scenario. The
amendments are intended to enhance
the anti-procyclicality approach to
address multiple price-based scenarios
as the Lehman Brothers’ default
scenario alone may not be sufficient. In
particular, the amendments are
intended to incorporate the Covid–19
stress scenario, in light of experience
during the pandemic. Amendments also
reflect the 20% portfolio gross margin
floor required under relevant European
regulation.3
Monte Carlo Implementation
The amendments would clarify that in
the MC implementation, distributions
are based on simulated constant
maturity CDS spread scenarios, and that
instrument profits or losses are
calculated by re-pricing instruments at
their coupons as well as their implied
recovery rates.
This change is intended to document
existing practices.
Data
The amendments would clarify
certain data fallbacks used by the
Clearing House when the normal
established EOD spread data is not
available. Consistent with current
practice, the amendments would
provide that if CDS spreads are not
available using the usual data sources,
then the ICE Clear Europe Clearing Risk
Department would use proxy log-returns
of existing clearable risk sub-factors
from a similar or correlated industry/
sector. In case ICE Clear Europe rolls out
risk factors already cleared at ICE Clear
Credit, the existing CDS spreads time
series would be used directly after
reviewing the back-test results. The
amendments would also clarify that
certain CDS spread time series are
available by risk sub-factor for the
relevant benchmark tenors.
The amendments would provide
additional detail as to the collection,
analysis and back testing of relevant
data for new risk sub-factors. Pursuant
to the amendments, if new risk
subfactors are to be rolled out, ICE Clear
Europe would collect prices from the
Clearing Members on the benchmark
tenors as per normal EOD price
discovery process before making the
contracts clearing eligible. The Clearing
Risk department would be responsible
for reviewing the fixed maturity time
3 European Market Infrastructure Regulation
(EMIR) Article 27.
E:\FR\FM\08MRN1.SGM
08MRN1
13424
Federal Register / Vol. 86, No. 43 / Monday, March 8, 2021 / Notices
jbell on DSKJLSW7X2PROD with NOTICES
series data on the benchmark tenors
until the first day of the price collection.
The backfilling of missing data would
be performed in log-return space
derived from the available EOD fixedmaturity spread levels. In general, the
5Y tenor time series would always be
available. If the original log-returns time
series presents incomplete data for less
actively traded tenors for only a few
days, then interpolation/extrapolation
techniques would be applied to derive
the missing data.
Once fixed maturity time series are
complete, ICE Clear Europe Clearing
Risk Department would perform backtests on hypothetical trading strategies
and stress tests on hypothetical
portfolios (i.e., by injecting bilateral
positions extracted from DTCC on the
sub-risk factor to roll out into cleared
portfolios of Clearing Members) in order
to further ensure that time series for the
new risk sub-factors are appropriate to
calibrate the risk models. The results of
the analyses would be presented to the
CDS Product Risk Committee.
Fixed maturity time series would be
transformed to constant maturity time
series (‘‘CMTS’’) to eliminate the impact
of semi-annual rolls. The amendments
provide further detail as to the manner
in which CMTS series are determined
and used for index and single-name risk
factors. These amendments are intended
to provide further clarity to the process
as described in the Risk Model
Description, but not significantly change
current Clearing House practice,
consistent with the existing Risk Model
Description.
The amendments would also provide
that back-testing results would be
available to assess the quality of time
series as well as the performance of the
calibrated models (instead of just the
latter).
Overall, these amendments relating to
data are intended to better document
existing practices and therefore are not
expected to change Clearing House
operation.
Testing
The Testing section would be
amended to provide that tests would be
broadly grouped into the following
categories: Stress tests; back-tests;
sensitivity tests; anti-procyclicality
tests; and benchmarking. The
amendments are generally intended to
reflect, and be consistent with the ICE
Clear Europe CDS Back-Testing Policy,
CDS Clearing Stress-Testing Policy, CDS
Parameters Review Procedures and Procyclicality Framework, and further
details of testing are provided in those
documents. With respect to
benchmarking, as currently described in
VerDate Sep<11>2014
19:05 Mar 05, 2021
Jkt 253001
the Risk Management Model
Description, ICE Clear Europe would
benchmark the spread response model
against the Model Carlo simulation
approach. Certain existing details
regarding back testing of the core model
components, comparing the calibrated
recovery rates used in the jump to
default requirement and actual market
data, assessing whether the assumed
stress scenario adopted to size the GF is
fit for purpose, testing the liquidity
component of the model, assessing
measures to mitigate the procyclicality
of the margins and testing margin
sensitivity would be removed as that
detail is contained in the ICE Clear
Europe Back-Testing Policy, CDS
Clearing Stress-Testing Policy, CDS
Parameters Review Procedures and Procyclicality Framework. The
amendments do not represent a
substantive change in ICE Clear
Europe’s approach to testing but are
intended to clarify the Risk Model
Description and to enhance it by more
clearly stating relevant assumptions.
Other Changes Throughout the
Documents
Minor typographical and drafting
updates are also proposed throughout
the Documents, including updating
references to Clearing Participants (or
CPs) to Clearing Members (or CMs) to be
consistent with the Rules, references to
Trading Advisory Committee (or TAC)
or Trading Advisory Group (or TAG) to
reflect that the TAG is not technically a
Clearing House committee, and Risk
Committee to Product Risk Committee
or CDS Product Risk Committee, as
appropriate, to reflect the correct name
of that existing committee.
CDS Parameters Review Procedures
ICE Clear Europe proposes to
formalize certain existing practices and
procedures for calibrating and reviewing
the core parameters and underlying
assumptions of its Risk Management
(‘‘RM’’) model that are not explicitly
described in its CDS Risk Model
Description and CDS Risk Policy into a
new Parameters Procedures document.
The Parameters Procedures thus
generally are not expected to change
existing Clearing House practice.
Parameters Setting and Calibration
ICE Clear Europe’s Parameters
Procedures would discuss the process of
setting and reviewing the model core
parameters and their underlying
assumptions. The model requirements
include Spread Response (‘‘SR’’)
requirements, Jump-To-Default (‘‘JTD’’)
requirements, basis risk requirements,
interest rate (‘‘IR’’) sensitivity
PO 00000
Frm 00146
Fmt 4703
Sfmt 4703
requirements, liquidity charge
requirements, and concentration charge
requirements.
Spread Response
The Parameters Procedures would
describe the parameters (and related
process for reviewing and updating
those parameters) that are associated
with the Spread Response components
of the CDS risk model, including as to
applicability (index or single name or
both), level of granularity (e.g., risk
factor), update frequency and the source
of the parameter estimations.
Time series associated with constant
maturity benchmark tenors would be
analysed and the distributions that
describe the fluctuations of the
benchmark tenors calibrated. The
statistical parameters update would be
performed at least on a monthly basis
and controlled and managed through
ICE Clear Europe internal systems.
The monitoring of the stress period
selected for the scale parameter would
be performed on a monthly basis in
accordance with the CDS Risk Model
Description. Proposed changes to the
stress period would be reviewed by the
Clearing House’s Clearing Risk
Department with its Risk Working
Group and MOC.
Jump-to-Default Requirement
Parameters
The parameters impacting the JTD
requirement are categorized as either
LGD or WWR parameters. The
Parameters Procedures would explain
how, in order to measure credit event
losses, the Clearing House’s Risk
Department constructs JTD scenarios in
terms of anticipated recovery rate
(‘‘RR’’) levels (‘‘RR scenarios’’). The
Parameters Procedures would describe
RR scenarios and estimations for
corporate SNs, sectors, and sovereign
reference entities, and notes foreign
exchange rate risk considerations with
respect to sovereign reference entities.
The Parameters Procedures would
require ICE Clear Europe to estimate and
review the LGD parameters at least
monthly and describes the associated
governance process, noting the
reviewers and any prerequisites to the
implementation of parameter updates.
The Parameters Procedures would
also detail the process of setting and
reviewing the WWR parameters. The
Parameters Procedures would contain
information regarding the parameters
that would be used to quantify WWR
dependence and to compute WWR JTD
requirements.
E:\FR\FM\08MRN1.SGM
08MRN1
Federal Register / Vol. 86, No. 43 / Monday, March 8, 2021 / Notices
Basis Risk Requirements
The Parameters Procedures would
discuss how the Clearing House’s Risk
Department maintains and monitors
hypothetical portfolios representing
basis trades between cleared index and
single-name instruments. Basis risk is
calibrated by comparing the P/Ls of
such portfolios to estimated IM
requirements, excluding any
concentration charges.
Interest Rate Sensitivity Requirements
The Parameters Procedures would
contain information on the estimation
and the review of the parameters that
serve as inputs to the IR sensitivity
component of the risk model. The IR
sensitivity component accounts for the
risk associated with changes in the
default-free discount term structure
used to price CDS instruments. With
respect to the IR sensitivity requirement
parameters, the Parameters Procedures
would specify how the risk department
estimates the up and down parallel
shifts for the US Dollar and Euro
default-free discount term structures.
The Parameters Procedures would direct
ICE Clear Europe to estimate and review
the IR sensitivity requirement
parameters at least monthly.
jbell on DSKJLSW7X2PROD with NOTICES
Liquidity Charge
The Parameters Procedures would
explain the process of setting and
reviewing parameters for the liquidity
charge component of the risk model.
With respect to index instruments, the
Parameters Procedures would address
the determination of bid/offer
parameters from the default spread
width matrix and other assumptions
about liquidation cost of an index
portfolio, and address procedures for
review of that matrix. The Parameters
Procedures would also describe the
parameters used in determining bid/
offer widths for single names, including
the use of price-based floor levels and
spread-based volatility measures. The
Parameters Procedures require the
Clearing House to review the liquidity
charge parameters at least monthly.
Concentration Charge
The Parameters Procedures would
discuss the estimation and the review of
the concentration charge parameters,
including detailing how the Risk
Department establishes series-specific or
SN-specific concentration charge
threshold levels for each index or SN
Risk.
Factor (‘‘RF’’), and how the Risk
Department estimates concentration
charge growth rates that determine how
quickly concentration charges increase
with position size. The Parameters
VerDate Sep<11>2014
19:05 Mar 05, 2021
Jkt 253001
Procedures direct the Clearing House to
estimate and review the concentration
charge parameters at least monthly.
Sensitivity Analysis
The Parameters Procedures would
detail the sensitivity analyses that the
Clearing House performs to explore the
sensitivity of the RM system’s outputs to
certain model core parameters that are
calibrated on an ad-hoc basis and to
alternative data analyses and parameter
estimation techniques. The Parameters
Procedures also provide for summary
reports of relevant analyses to be
provided to the Risk Oversight
Department or other relevant groups.
Portfolio Benefits Parameters
The portfolio benefits parameters
control portfolio benefits during the
computation of the SR with the stress
based VaR approach. The Parameters
Procedures would describe the methods
for monitoring the benefits and
performing sensitivity analysis of
potential parameter changes that would
reduce benefits.
Dependence Structure Shifts
The Parameters Procedures also
address sensitivity analysis of portfolio
benefits implemented during the
computation of the SR under the MC
simulation approach, based on different
dependence structures. The approach is
intended to guide the Risk Department
in situations where back-testing results
indicate excessive portfolio benefits.
SWWR Threshold Shift
The Parameters Procedures would
address sensitivity analysis with respect
to model parameters that control the
permitted level of index derived SWWR,
to provide guidance to the Risk
Department in situations when a
decision to fully collateralize SWWR is
made upon a consultation with the
Model Oversight Committee and the
Product Risk Committee.
GWWR Correlation Shifts
Sensitivity analysis also considers
GWWR arising from Clearing Members
exposed to Western European
Sovereigns when the Kendall tau rankorder correlation between the Member
and the Sovereign entity is above a
threshold. The sensitivity analysis
would be to provide guidance to the risk
departments in situations when an
increase of the dependence among
members and sovereigns might lead to
changes in risk requirements.
MAD Level Shifts
The Parameters Procedures would
describe sensitivity analysis on MAD
PO 00000
Frm 00147
Fmt 4703
Sfmt 4703
13425
levels, which is performed by shifting
all MAD estimates to their stress levels
to provide information about the
response of risk requirements to
potential volatility shifts and to assess
the viability of certain parameter-setting
assumptions. This sensitivity analysis
would be to provide guidance to the
Risk Department about potential risk
requirement changes in stress periods
due to increase in volatility shifts.
EWMA Sensitivity Analysis
The Parameters Procedures would
address sensitivity analysis relating to
the setting of the exponentially
weighted moving average (‘‘EWMA’’)
decay rate (‘‘EWMA factor’’), which may
affect the procyclicality of the model.
Statutory Basis
ICE Clear Europe believes that the
amendments to the Documents and the
adoption of the Parameters Procedures
are consistent with the requirements of
Section 17A of the Act 4 and the
regulations thereunder applicable to it.
In particular, Section 17A(b)(3)(F) of the
Act 5 requires, among other things, that
the rules of a clearing agency be
designed to promote the prompt and
accurate clearance and settlement of
securities transactions and, to the extent
applicable, derivative agreements,
contracts, and transactions, the
safeguarding of securities and funds in
the custody or control of the clearing
agency or for which it is responsible,
and the protection of investors and the
public interest.
The amendments to the Documents
and the adoption of the Parameters
Procedures are generally designed to
enhance and clarify the descriptions of
key ICE Clear Europe risk models and
documentation used in determining
CDS margin and GF requirements,
particularly in the CDS Risk Policy, CDS
Risk Model Description and CDS Endof-Day Pricing Policy. Although these
changes are largely not intended to
represent a change in Clearing House
practices, they should enhance the
clarity and ongoing monitoring and
implementation of these policies. The
amendments also make a number of
changes to the CDS Stress Testing
Policy, which are intended to add new
stress scenarios relating to the COVID–
19 pandemic, in light of experience in
early 2020, and clarify more generally
that certain extreme scenarios should
not be limited to scenarios relating to
the Lehman Brothers default. The
amendments also adopt a new set of
Parameters Procedures, which is

intended to codify and formalize the
Clearing House’s approach to setting the
key parameters used in the CDS risk
model, conducting related sensitivity
analyses of the impact of such
parameters and reviewing such
parameters on an ongoing basis. As
such, the Parameters Procedures
support ICE Clear Europe’s ability to
maintain sufficient margin requirements
and enhance ICE Clear Europe’s
approach to identifying potential
parameter changes that are appropriate
to maintain the operation of the risk
model and thereby ensure that the
Clearing House continues to maintain
sufficient financial resources to
withstand defaults by Clearing
Members. Therefore, the amendments to
the Documents, and the adoption of the
Parameters Procedures, will help ICE
Clear Europe ensure that it maintains
adequate financial resources to support
its CDS operations, enhance the stability
of the Clearing House and overall
promote the prompt and accurate
clearance and settlement of securities
transactions and, derivative agreements,
contracts, and transactions, the
safeguarding of securities and funds in
ICE Clear Europe’s custody or control or
for which ICE Clear Europe is
responsible, and the public interest in
the sound operation of clearing
agencies. Accordingly, the amendments
are consistent with the requirements of
Section 17A(b)(3)(F).6
For similar reasons, the amendments
and the Parameters Procedures also are
consistent with relevant requirements of
Rule 17Ad–22. Rule 17Ad–22(e)(3)(i) 7
requires clearing agencies to maintain a
sound risk management framework that
identifies, measures, monitors and
manages the range of risks that it faces.
The various amendments throughout
the Documents as well as the new
Parameters Procedures document are all
intended to clarify the operation of ICE
Clear Europe’s risk management systems
and provide for enhanced stress testing.
They provide greater clarity with
respect to various risk management
tools, ensure that COVID–19 and other
extreme but plausible stress scenarios
are accounted for and ensure current
governance practices are clearly set out,
all of which facilitate ICE Clear Europe’s
compliance with Rule 17Ad22(e)(3)(i).8
In addition, ICE Clear Europe believes
that the adoption of the Parameters
Procedures are consistent with the
relevant requirements of Rule 17Ad–
22(e)(4)(vi)(B),9 which requires ICE

Clear Europe to identify, measure,
monitor and manage its credit exposures
to participants and those arising from its
payment, clearing, and settlement
processes, including by testing the
sufficiency of its total financial
resources available to meet the
minimum financial resource
requirements, including by conducting a
comprehensive analysis of underlying
parameters and assumptions on at least
a monthly basis. The Parameters
Procedures would also provide a clear
framework for ICE Clear Europe to
estimate and review the model core
parameter settings and perform and
review sensitivity analyses related to
certain parameter settings on at least a
monthly basis. The amendments to the
CDS Stress Testing Policy will, as
discussed above, enhance the stress
testing of the Clearing House by
incorporating a wider range of extreme
scenarios (including those reflecting
recent market events) in stress testing,
which are reviewed on at least a
monthly basis. Other amendments
would clarify how the Clearing Risk
Department would address a scenario or
portfolio in the standard set of stress
scenarios no longer being applicable, or
being superseded by new scenarios or
portfolios, where the Clearing Risk
Department wishes to retire or modify
the outdated scenario or portfolio or add
a new scenario. The amendments serve
to promote the soundness of the
Clearing House’s risk management
model and system and ensure that the
Clearing House possesses the ability to
manage the risks associated with
discharging its responsibilities,
consistent with the requirements of Rule
17Ad–22(e)(4)(vi)(B).10
Rules 17Ad–22(e)(2)(i) and (v) 11
requires that clearing agencies provide
for governance arrangements that are
clear and transparent and specify clear
and direct lines of responsibility.
References to the roles of certain
committees and departments with
respect to reviews and approvals
throughout the Documents have been
updated to better reflect existing
practice with respect to the roles of
groups. Where appropriate, references to
the MRGF, which sets out further
governance details, have been added
throughout the documents. The
amendments provide additional clarity
with respect to Clearing House
governance and lines of responsibility
consistent with Rules 17Ad–22(e)(2)(i)
and (v).12
Rule 17Ad–22(e)(6)(iv) 13requires that
clearing agencies cover their credit
exposures to participants by
establishing a risk-based margin system
that uses reliable sources of timely price
data and uses procedures and sound
valuation models for addressing
circumstances in which pricing data are
not readily available or reliable.
Amendments to the CDS Model Risk
Description would more clearly state the
procedures for determining relevant
prices should input data not be
available from back-up sources, further
strengthening ICE Clear Europe’s
strategies to ensure it has access to
reliable sources of timely price data in
compliance with this requirement. The
amendments would also provide further
detail regarding the treatment of data
collected and the backfilling of missing
data. The amendments to the CDS Risk
Policy would also strengthen the quality
of intraday prices through enhanced
intraday monitoring through additional
comparisons of intraday prices with
other ICE CDS clearing houses and
third-party providers. Together, the
amendments strengthen ICE Clear
Europe’s compliance with Rule 17Ad–
22(e)(6)(iv).14
Rules 17Ad–22(e)(6)(i) to (iii) 15
require that clearing agencies establish a
risk-based margin system that (i)
considers, and produces margin levels
commensurate with, the risks and
particular attributes of each relevant
product, portfolio, and market; (ii)
marks participant positions to market
and collects margin, including variation
margin or equivalent charges if relevant,
at least daily and includes the authority
and operational capacity to make
intraday margin calls in defined
circumstances; and (iii) calculates
margin sufficient to cover its potential
future exposure to participants in the
interval between the last margin
collection and the close out of positions
following a participant default. The
proposed amendments would provide
more detail regarding the IM
methodology set out in the CDS Risk
Policy, facilitating the maintenance of
sufficient margin levels. The CDS Risk
Policy amendments would also provide
that in the event that ICE Clear Europe
is accepting sizable positions through
the weekly back-loading process in the
context of margin calls, it will precollect IM and mark-to-market changes,
instead of just IM, to further ensure
sufficient margin collection.

system and compliance with Rules

(B) Clearing Agency’s Statement on
Burden on Competition
ICE Clear Europe does not believe the
proposed rule changes would have any
impact, or impose any burden, on
competition not necessary or
appropriate in furtherance of the
purpose of the Act. The amendments to
the Documents and the new Procedures
apply to all CDS Contracts. In general,
the amendments are intended to clarify
the description of the CDS risk model,
and not substantially change the
practices of the Clearing House with
respect to the calculation of CDS margin
and GF requirements. As such, the
amendments will apply to all CDS
Clearing Members and are unlikely, in
ICE Clear Europe’s view, to materially
affect the cost of clearing for CDS
products or affect access to clearing for
CDS products at ICE Clear Europe or the
market for cleared services generally.
Certain amendments to the CDS Stress
Testing Framework would add new
stress-testing scenarios in light of recent
events, including COVID–19 related
scenarios. To the extent such
amendments may have any impact on
margin levels, ICE Clear Europe believes
such changes will be appropriate in
furtherance of the risk management of
the Clearing House in light of the market
movements observed during the
pandemic. Therefore, ICE Clear Europe
does not believe the proposed rule
changes impose any burden on
competition that is inappropriate in
furtherance of the purposes of the Act.

I. Clearing Agency's Statement of the Terms of Substance of the
Proposed Rule Change
ICE Clear Europe Limited proposes to modify certain provisions of
its CDS Clearing Stress Testing Policy, CDS End of Day Price Discovery
Policy, CDS Risk Model Description and CDS Risk Policy (together, the
``Documents'') and to adopt a new document titled CDS Parameters Review
Procedures (the ``Parameters Procedures'').
II. Clearing Agency's Statement of the Purpose of, and Statutory Basis
for, the Proposed Rule Change
In its filing with the Commission, ICE Clear Europe included
statements concerning the purpose of and basis for the proposed rule
change and discussed any comments it received on the proposed rule
change. The text of these statements may be examined at the places
specified in Item IV below. ICE Clear Europe has prepared summaries,
set forth in sections (A), (B), and (C) below, of the most significant
aspects of such statements.
(A) Clearing Agency's Statement of the Purpose of, and Statutory Basis
for, the Proposed Rule Change
(a) Purpose
ICE Clear Europe is proposing to amend the Documents and institute
the new Parameters Procedures principally to describe more fully
certain existing Clearing House practices, as discussed herein. ICE
Clear Europe is also proposing to make certain enhancements to CDS
stress testing, specifically to incorporate the impact of the COVID-19
pandemic into its stress testing framework.
CDS End of Day Price Discovery Policy
The amendments to this policy would generally clarify the process
to determine prices for a particular instrument when fewer than three
Clearing Members have open interest in that instrument, in order to
provide more reliable pricing in that scenario. The amendments would
also make minor terminology updates to conform uses of defined terms,
correctly reference various ICE Clear Europe personnel and operations
and make similar typographical corrections throughout the document and
add a new table.
Currently, the CDS End of Day Price Discovery Policy states that if
fewer than three CDS Clearing Members have cleared open interest in an
instrument, ICE Clear Europe may require all CDS Clearing Members to
provide a price submission for that instrument. ICE Clear Europe
proposes to supplement this concept to provide more flexibility to
ensure enough submissions to enable effective determination of reliable
end-of-day prices and thereby facilitate an accurate and stable
variation margin process. Specifically, the amendments are designed to
produce more reliable prices by increasing the probability of receiving
multiple submissions. As amended, the policy would state that ICE Clear
Europe believes that tradeable quotes submitted by CDS Clearing Members
are the preferred source of data and should be used where possible and
reliable, meaning where there is more than one CDS Clearing Member with
which the quote could be crossed. Where there are not enough CDS
Clearing Members to enable tradeable quotes (i.e., quotes at which a
member would transact) to be crossed with more than one CDS Clearing
Member (i.e., fewer than three CDS Clearing Members
[[Page 13418]]
with open interest in the relevant instrument), then ICE Clear Europe
would switch to rely on indicative quotes and would require these from
all CDS Clearing Members. (For this purpose, an indicative quote is a
reasonable estimate of the market price but does not necessarily
reflect a price at which the member would transact.) When requesting
indicative quotes in this manner, ICE Clear Europe would not require
CDS Clearing Members to enter into firm-trades in these instruments.
The minimum number of three CDS Clearing Members, below which
indicative quotes would be used, would be subject to ongoing review by
ICE Clear Europe as to whether this is the appropriate threshold given
market circumstances.
A new Table 4 showing an example of an assignment of index risk
factors to market proxy groups would be added pursuant to the
amendments relating to end-of-day bid-offer widths (``EOD BOWs'') for
index instruments. The new table does not reflect a change in practice
and is intended for clarity. The table would show the index risk
factors for each of the CDX and iTraxx market proxy groups. A reference
to Table 2 in the EOD BOWs section would be updated to Table 4.
Existing references to Tables 4 through 7 would be respectively updated
to Tables 5 through 8.
In the governance section addressing material changes to the EOD
price discovery methodology, spread-to-price conversion determinants or
parameters, the amendments would clarify that review would be performed
by the TAG (instead of the TAC) and the Product Risk Committee (instead
of the Risk Committee). This amendment is intended to reflect current
practice.
Numerous minor typographical and similar updates would be made
throughout the CDS End of Day Price Discovery Policy. For example, the
term ``Clearing Participant'' would be updated to ``Clearing Member'',
``CP'' would be updated to ``CM'' and ``Trading Advisory Committee''
(or ``TAC'') would be updated to ``Trading Advisory Group'' (or
``TAG''), to be consistent with terminology used in the Rules and other
ICE Clear Europe documentation. The statement that the trading desks at
each self-clearing member (``SCM'') would be required to copy ICE Clear
Europe on the intraday quotes they provide market participants via
email would be updated to requested to copy. Certain outdated cross-
references would be removed. With respect to the red matters in the
escalation and notification protocol for appetite metrics, the Board
and Executive Risk Committee would be notified immediately instead of
as soon as possible. Other minor clean-up changes would also be made to
improve readability and clarity.
CDS Clearing Stress Testing Policy
ICE Clear Europe is proposing to add new stress test scenarios to
this policy and to make certain other clarifications and enhancements
to the description of the stress-testing methodology in order to
capture the large market moves experienced during the COVID-19
pandemic, strengthen the CDS discordant stress test scenarios and
better reflect the current governance structure related to stress
testing.
Purpose
The discussion of the purpose of Clear House stress testing
practices, including as to how they are integrated into ICE Clear
Europe's risk procedures and governance structure, would be revised to
reflect the Clearing House's current governance framework, and
specifically to reference the Model Oversight Committee (``MOC'') and
to remove an outdated reference to the Board Risk Committee (``BRC'').
The amendments would also provide that any terms not defined in the
policy would be defined in the ICE Clear Europe CDS Risk Policy and the
Rules, instead of only in the Rules.
Methodology
The general methodology section of the policy would be amended to
add a discussion of stress testing in the context of wrong way risk.
For this purpose, positions in index risk factors and single-name risk
factors that exhibit high levels of association with a Clearing
Member's portfolio are combined in a sub-portfolio, which is subject to
additional stress testing analysis. The amendments to this section do
not reflect a change in Clearing House practice but are intended to
better document existing practice.
The amendments also revise the governance process where a scenario
or portfolio in the standard set of stress scenarios is no longer
applicable, or is superseded by new scenarios or portfolios, and the
Clearing Risk Department wishes to retire or modify the outdated
scenario or portfolio. In that case, the Clearing Risk Department would
conduct an analysis to determine whether a change is significant, which
would be reviewed by the Risk Oversight Department (``ROD''). The
Board, or its delegated committee, would approve the significant
decommissioning of scenarios, while the Model Oversight Committee
(``MOC'') would approve the decommissioning of scenarios (if not
significant) or recommend the decommissioning of scenarios to the Board
if deemed significant. The amendment is intended largely to formalize
current practice, and also reflect the role of the MOC under the
Clearing House's Model Risk Governance Framework (the ``MRGF''). The
existing description of the steps that the Clearing Risk Department
would take in such a scenario (involving approval by the relevant risk
committee) would be deleted. The amendments would also clarify that if
the Clearing Risk Department wishes to add new scenarios or portfolios,
the MOC must approve of the addition, but the Board's approval is not
required. This is a change from the current procedure, under which it
is sufficient to simply inform the CDS Risk Committee.
Further, the amendments would also state explicitly that in stress
testing and sensitivity testing, under the multiple Clearing Member
default scenario, conditional uncollateralized loss-give-defaults
(``LGDs'') resulting from Clearing Member single-name positions would
also be explicitly incorporated. This reflects current practice.
Various Changes
Various defined terms would be updated throughout the document. The
CDS Product Risk Committee would be referred to as the CDS PRC instead
of the CDS RC. Members or Clearing Members would be referred to as CMs.
Throughout the document, references to Initial Margin would be updated
to IM and references to Guaranty Fund would be updated to GF.
Changes to Predefined Scenarios; New COVID-19 Scenarios
The introductory description of the predefined scenarios would be
amended to clarify that the scenarios reflect a stress period of risk
from 1 to 7 days (referred to in the policy as ``N''-day scenarios),
taking into account the 5-day margin period of risk used in the
existing margin methodology for house accounts and the 7-day margin
period of risk used in the existing margin methodology for client
accounts. The description of the magnitude of the base ``FX Stress
Scenario'' would be amended to state that it reflects the greatest
relevant N-day stress period (instead of five days).
Overall, the changes to the stress testing scenarios, other than
the addition of the new COVID-19 scenarios, are intended to more
thoroughly describe the stress test
[[Page 13419]]
scenarios. The changes (including the addition of the COVID-19
scenarios) are not expected to result in any changes in margin levels
or other financial impact on the Clearing House or Clearing Members.
Extreme but Plausible Market Scenarios
The amendments would update the description of the extreme but
plausible market scenarios. The description of the 2008/2009 credit
crisis scenario would be updated to state that the widening/tightening
credit crisis spread scenarios are based on the greatest observed N-day
(instead of five-day) relative spread increases/decreases expressed as
percentages. The amendments would also clarify that the determination
of the exact stress period is defined by the greatest observed spreads
change of the Most Actively Traded Instruments (``MATI'') for each
relevant sub-portfolio. The stress spread changes, defined for each
Index, corporate and sovereign risk factor (``RF''), would be extracted
from the market history for the MATI of the considered RF. Amendments
would also clarify that the other three historically observed stress
test scenarios from the 2008/2009 period would be based specifically
around the period surrounding Lehman Brothers' default to capture the
large market moves of that period. These amendments are intended to
provide a more thorough description of these existing stress testing
scenarios.
The description of the Western European credit crisis scenarios
would similarly be clarified to state explicitly that the scenarios
replicate the stress market moves resulting from the concerns around
the debt sustainability of several Eurozone countries. Widening/
Tightening Western European Credit Crisis Spread Scenarios would be
based on the greatest observed Nday (instead of five-day) relative
spread increases/decreases (which would no longer be restricted to the
most actively traded instruments). Amendments would also clarify that
the determination of the exact stress period would be defined by the
greatest observed spreads change of the MATI for each sub-portfolio.
The other three historically observed stress test scenarios would be
based specifically around the second quarter of 2010 to capture the
large market moves of that period. The spread shocks would be expressed
in percentage for each RF. These amendments are intended to provide a
more thorough description of these existing stress testing scenarios.
The description of the Lehman Brothers Default Price Change
Scenario would be expanded. The amendments would state that the
scenario magnitudes are defined for each RF according to its sector
classification and time to maturity of the considered instrument. The
corresponding stress test Opposite LB Default Price Change Scenarios
would be derived from the Lehman Brothers scenarios by means of
multiplying the scenario result by a negative factor to reflect the
reduced magnitudes of the observed price increases during the
considered period. These amendments are intended to provide a more
thorough description of these existing stress testing scenarios.
New COVID-19 Based Scenarios
Given that moves in both spreads and prices were, generally, higher
than other observed extreme but plausible stress test scenarios during
the COVID-19 pandemic, ICE Clear Europe is proposing to add the
following additional COVID-19 pandemic fear scenarios based on stress
market moves experienced between February and April 2020:
The COVID-19 Widening/Tightening Spread Scenarios, which
would be based on the greatest observed N-day relative spread
increases/decreases during the period. The determination of the exact
stress period would be defined by the greatest observed N-day spread
changes of the MATI for each sub-portfolio; and
The COVID-19 Price Decrease Scenario would be defined in
price space to maintain the stress severity during periods of low
spread levels and high prices, when the IM requirements are expected to
be lower. The scenario would be based on the greatest observed N-day
relative price decreases during the aforementioned period. The
determination of the exact stress period would be defined by the
greatest observed N-day spread changes of the MATI for each sub-
portfolio. A corresponding stress test COVID-19 Price Increase Scenario
would be derived from the price decrease scenario by applying factors
for Indices and SNs to reflect the reduced magnitudes of the observed
price increases during the considered period.
Discordant Scenarios
The scope of discordant spread scenarios (for corporates and
sovereigns) would be clarified. Specifically, the description of the
corporate discordance spread scenarios would reflect that such
scenarios are based specifically on discordant moves along the major
European and North American 5Y on-the-run (OTR) indices. The amendments
would also state that the corporate SNs and indices discordant spread
scenarios, which reflect realizations when certain indices or sub-
indices for the EU region and certain U.S. OTR indices exhibited the
greatest combined discordant change, would be created and applied to
SNs and Indices. The amendments would further update references to
indices used in stress scenarios and state that other stress scenarios
would be based on discordant spread realizations across European
Indices. The amendments would also note that other stress scenarios
would reflect discordant spreads realizations among geographical
regions. These amendments are intended to provide a more thorough
description of existing stress testing scenarios.
Hypothetical Scenarios
With respect to hypothetical scenarios, greater detail would be
added to clarify that the curve inverting spread scenario is based on
the largest widening shock among the 2008/2009 Credit Crisis Widening
and the Western European Credit Crisis Widening for each RF. Similarly,
the curve steepening spread scenario is based on the largest tightening
shock among the 2008/2009 Credit Crisis Tightening and Western European
Credit Crisis Tightening scenarios.
New sectors and countries discordant scenarios would also be added.
These scenarios would be designed to reproduce discordant moves across
sectors and entities of different countries, noting that the large
price moves in the oil benchmark products (especially WTI negative
prices) in the first half of 2020 created asymmetric shocks to the
energy and financials sectors compared to other sectors, which would be
reflected in the Energy vs Other Sectors Discordant scenario. The five-
year spread shocks would be estimated at sector level, and the
derivation of the shocks for the other tenors would be based on the
tenor-specific inverting and steepening factors. The sector-specific
shocks would then be applied to all RFs within the sector. The opposite
stress scenario would also be considered for completeness. The spread
shocks estimated for the clearable Western European Sovereigns would be
applied to the European corporate SNs for each country. The opposite
stress scenario would also be considered for completeness.
Another hypothetical scenario, the forward-looking credit events
scenarios, would be updated to clarify that the Clearing Member
reference entity that would be considered would be different from the
Clearing Member whose portfolio is subject to the stress test.
[[Page 13420]]
They would also add that the reference entity is assumed to enter in a
state of default and thus create Loss Given Default (``LGD'') and that
a reference entity is selected that creates the largest LGD exposure,
rather than the greatest one-year EOD spread level.
Extreme Market Scenarios
The amendments would clarify that extreme steepening and extreme
inverting scenarios would be created from crises steepening and crises
inverting scenarios by doubling the shocks for inverting scenarios and
applying a factor to steepening scenarios. The amendments would also
incorporate the new COVID-19 historical scenarios into the
determination of extreme scenarios, similar to the calculation of
extreme scenarios based on the LB default scenario.
With respect to the guaranty fund (``GF'') scenarios, greater
specificity would be provided to clarify that the stress test scenarios
would be designed to account for the occurrence of credit events for
two Clearing Member risk factor groups (``RFGs'') and three non-
Clearing Member RFGs. The amendments would also clarify that the GF
scenario considers an even more extreme case in which five RFGs undergo
credit events (changing a reference from single names to the more
accurate RFG). The chart setting out the quantile ratios for the
student t distributions with different shape parameters would be
removed as unnecessary.
The GF adequacy analysis would be amended to state that as the
number of defaults of reference entities is one of the major risks in
the CDS clearing service, the Clearing Risk Department considers
complementary extreme scenarios where a combination of up to five RFGs
for up to five Clearing Members would be assumed to default before
simulating spreads widening and tightening on the non-defaulting
entities in order to fully deplete the GF. The amendments would explain
that the scenario aims at providing estimates of the level of
protection achieved through initial margin (``IM'') and GF in relation
to multiple defaults. This amendment is intended to clarify the stress-
testing description but does not reflect a change in current stress
testing practice.
Portfolio Selection
The description of the process for determination of sample
portfolios for stress testing would be updated to reflect that ICE
Clear Europe would derive the portfolio from the currently cleared
portfolios by considering only positions in index RFs and sectors that
exhibit a high degree of association with the considered Clearing
Member, in particular indices, sovereigns and financials RFs (rather
than considering exactly the opposite positions from the currently
cleared portfolio). The constructed sub-portfolios would be subject to
the stress test analysis with the standard set of stress test
scenarios. The aim of the stress analysis with the sample portfolios
would be to provide estimates to the potential exposure of Clearing
Members to RFs generating general wrong way risk (``WWR''). The current
reference to special strategy sample portfolios would be deleted, and a
new provision would address application of stress testing scenarios to
expected future portfolios upon the launch of new services and RFs. The
stress test analysis would be presented and reviewed by the CDS Product
Risk Committee prior to launch of the new RFs.
Interpretation and Review of Stress-Testing Results
The interpretation and review of the stress-testing results section
would be amended to provide that enhancements to stress scenarios would
be discussed and approved based on the governance outlined in the MRGF.
The amendments would also clarify that the two greatest affiliate
groups' (``Cover-2'') uncollateralized stress loss associated with
scenarios characterized as extreme but plausible market scenarios
should be covered by funded default resources (excluding potential
assessments). If Cover-2 protection under these scenarios is not
achieved, additional funds could be required to cover the shortfall and
enhancements to the current risk methodology would be considered. The
amendments would further provide that the Board and its delegated
committees (instead of the CDS Risk Committee and Board Risk Committee)
would be provided with information as to the stress test results as
necessary or appropriate to perform their duties. The amendments are
intended to allow the Board the flexibility to determine the
appropriate committees for review of stress testing.
Certain outdated statements would be removed, including matters
relating to governance that are addressed in the MRGF as well as
outdated references to certain examples or specific committees. As
discussed in the methodology section above, any related deficiency
analysis and review would be undertaken by the MOC instead of the
Executive Risk Committee, in accordance with the procedures of the
MRGF. The stress testing report would be presented to the CDS Product
Risk Committee instead of the CDS Risk Committee during scheduled
meetings (instead of scheduled monthly meetings).
The amendments would specifically remove the following statements:
The statement as to the stress scenarios that lead to
model review include;
the statement that the hypothetical losses generated in
response to stress scenarios are compared to the available margins on
deposit and Guaranty Fund contributions and if applicable, the ICE
Clear Europe contribution to the risk waterfall and the funds available
through the one-time limited assessment from each Clearing Member;
the statement that ICE Clear Europe is responsible for
identifying in which zone a particular stress test result falls; and
statements as to certain functions of the Clearing Risk
Department, Clearing Risk senior management, ERC, CDS RC, the BRC and
the Board, which have been replaced by the role of the MOC and the
other revised governance arrangements discussed above.
Policy Governance and Reporting
The policy governance and reporting section would be amended to
remove the requirement that the policy be reviewed annually by the CDS
Risk Committee and only would require review by the Board Risk
Committee. Material changes to the policy would be discussed by the MOC
(instead of the ERC) and approved by the Board on the advice of the CDS
Product Risk Committee and the Board Risk Committee prior to
implementation. These amendments are intended to be more consistent
with other Clearing House governance processes and formalize existing
arrangements to ensure that appropriate bodies are engaged in policy
governance.
Appendix
The FX stress test scenario amendments would reflect the greatest
N-day relative depreciation (instead of five-day) and would remove the
specific dates. This is intended to be a conforming change consistent
with the other amendments to use an N-day period described above.
CDS Risk Policy
The amendments to this policy would describe more fully the
existing use of the Clearing House's Monte Carlo (``MC'') simulation
approach in the context of establishing initial margin and GF
requirements. The amendments would also generally clarify the use and
[[Page 13421]]
source of intraday prices and make other drafting improvements and
clarifications, including through revising certain descriptions and
providing certain defined terms. The amendments simplify certain cross
references to the CDS Risk Model Description throughout the policy by
removing unnecessary section references (to facilitate keeping the CDS
Risk Policy up to date). In general, the amendments are intended to
provide a clearer explanation of the Clearing House's methodology for
IM and GF requirements and are not intended to materially change the
methodology or to change the levels of IM and GF requirements.
With respect to IM, the amendments would clarify the description of
the IM methodology by stating that the risk protection measure is based
on using a combined approach featuring a stress-based spread response
Value-at-Risk (``VaR'') measure and a Monte Carlo (``MC'') simulation
spread response VaR measure. They would also add that model performance
would be monitored through stress testing and sensitivity analyses. The
amendments are intended to more clearly reflect existing practices, and
would not change the IM methodology.
With respect to the spread response requirements description, the
amendments would provide greater clarity that the spread response risk
requirement that captures credit spread fluctuations is a stress-based
spread response that computes Profit/Loss (``P/L'') distributions from
a set of simulated hypothetical (forward looking) credit spreads
scenarios.
The description of the stress-based spread response scenarios would
be modified by rewording the introduction to improve readability and to
clarify the applicable benchmark tenors estimated for all the Risk Sub-
factors, replacing certain outdated references to tenors. The
amendments are intended to reflect and more clearly describe current
practices.
A new section would be added to describe in more detail the Monte
Carlo simulation approach currently used by the Clearing House. The
amendments would provide that in this approach, ICE Clear Europe
generates spread scenarios by means of student-t copulas to connect the
univariate distributions that describe spread fluctuations. The
student-t copulas reflect historical estimates of Kendall [tau]
correlation coefficients to simulate spread log-returns.
The simulated copula scenarios are used to arrive at hypothetical
spread levels by means of estimated univariate spread log-return
distributions. Each instrument would be repriced at the simulated
spread levels to generate a scenario instrument P/L based on post-index
decomposition positions. For each scenario, instrument P/Ls would be
aggregated according to pre-defined RFs and sub-portfolio position sets
in order to obtain RF and sub-portfolio P/Ls.
These distributions would be used to estimate the RF and sub-
portfolio 99.5% VaR measures at a chosen risk horizon. The portfolio
level integrated Spread Response would be estimated as a weighted sum
of RF and sub-portfolio 99.5% VaR measures.
The description of the anti-procyclicality considerations would be
updated to provide that the stress price changes would be derived from
the price-based extreme but plausible stress test scenarios under the
revised CDS Stress Testing Policy, as described above, instead of only
from the market behavior during and after the Lehman Brothers default
period.
Throughout the policy, references to the risk department would also
be updated to the Clearing Risk Department.
The amendments also provide that the Clearing Risk Department may
recommend margin methodology changes based on the governance procedures
outlined in the MRGF, consistent with the requirements of that
framework. The amendments would also note that in the event that ICE
Clear Europe is accepting sizable positions through the weekly back-
loading process in the context of margin calls, it will pre-collect IM
and mark-to-market changes, instead of just IM.
With respect to mark-to-market margin (``MTMM''), the description
regarding the determination of cash owing, the payment of MTMM, the
timing of margin calculations and the making of MTMM calls would be
removed as unnecessary operational detail. These matters are also
generally covered in the CDS Risk Policy and Finance Procedures.
Similarly, the discussion of the requirements and rights of a Clearing
Member upon a change in MTMM balance (i.e. to pay or be credited cash)
would be deleted as unnecessary detail.
With respect to intra-day monitoring, the amendments would provide
that ICE Clear Europe would ensure the quality of the intraday prices
by monitoring and comparing the quotes received with the intraday
prices of the transactions cleared at ICE CDS clearing houses. ICE
Clear Europe could also compare intraday prices with those of another
third-party provider. The comparison process would be carried out
before issuing intraday margin calls. The description of the intraday
risk limit calculation would be updated such that it would be based on
40% of the total IM requirements, with a minimum amount corresponding
to the minimum GF contribution and would be capped at a monetary amount
reviewed in conjunction with the ICE Clear Europe senior management and
the CDS Product Risk Committee. The precise monetary amount would be
removed from the policy to give the Clearing House flexibility if it
determined it was appropriate to review and reconsider this amount in
the future in conjunction with senior management and the BRC. There is
currently no plan to change the existing EUR 100 million cap in
practice. The procedure for intra-day margin calls would be further
clarified by removing a statement that where there has been a 50%
erosion of the Intraday Risk Limit, the Risk Department will
investigate the matter. In ICE Clear Europe's view, a separate step at
the 50% erosion level is unnecessary, as ICE Clear Europe will not take
any particular action at that level. Once the erosion exceeds 50%, the
Clearing Risk Department is required to inform the relevant CDS
Clearing Member that it may be subject to an intraday margin call (and
in so doing the Clearing Risk Department will make any necessary
investigations of the matter).
The statement that the Risk Management Department will notify the
ICE Clear Europe Treasury Department of the ``special'' margin call
would be removed as an operational detail not necessary for the policy.
Generally, the Clearing Risk Department sets the margin level and would
communicate it to other departments in the ordinary course, as it does
for any change of margin level.
With respect to the GF, the amendments would update the drafting of
certain language (including the reference to the ``Cover 2''
requirement) to remove certain unnecessary detail. With respect to
related anti-procyclicality considerations, the amendments would refer
to the extreme but plausible price-based stress test scenarios
described in the revised CDS Clearing Stress Testing Policy, as
discussed above. Amendments would also provide that the GF allocation
process is performed by the Clearing Risk Department on a weekly basis
rather than every Thursday and based on the previous business day's
close of business positions rather than Wednesday's close of business
positions. The amendments would also
[[Page 13422]]
clarify that the requirement that a portion of the GF be in USD is
intended to accommodate all USD-denominated CDS contracts, not merely
sovereign CDS contracts . . . The current numerical example of GF
calls/collection would be removed as unnecessary.
With respect to back-testing, the amendments provide if the model
calibration consistently demonstrates exceptions outside of the
coverage level, the Clearing Risk Department would review the models
and recommend revisions following the governance procedures outlined in
the MRGF.
Pursuant to the amendments, the stress-testing section would add
that the historical data would account for COVID-19 outbreak fear,
consistent with the changes to the CDS Stress Testing Policy discussed
above.
The amendments would update certain terms throughout the document
as follows: ICE Clear Europe would be referred to as ICEU; Member,
member or Clearing Member would generally be updated to CM; Risk Model
Description would be updated to CDS Risk Model Description; CDS Risk
Committee would be updated to CDS Product Risk Committee; Risk
Department, Risk Management Department or Clearing Risk department
would be updated to Clearing Risk Department; General Wrong Way Risk
would be referred to as ``GWWR''; Guaranty Fund would be updated to GF,
Specific Wrong Way Risk would be abbreviated as SWWR; Model Oversight
Committee would be given the acronym ``MOC''; the Model Risk Governance
Framework would be given the acronym ``MRGF''; Initial Margin would be
updated to IM; Dollar would be updated to USD; CDS Back Testing
Framework would be updated to Policy; a Risk Oversight Committee
reference would be updated to ROC; CDS Risk Product Committee and CDS
RC would be respectively updated to CDS Product Risk Committee and CDS
PRC; and Risk Committee would be updated to CDS PRC. Certain other
typographical corrections would be made.
CDS Risk Model Description
This document was amended in May 2019 (the ``2019 Amendments'') and
additional amendments are currently being proposed (the ``Current
Amendments''). As discussed below, the Current Amendments would:
Clarify the treatment of volatility estimates for the
Recovery Rate Sensitivity Requirement (``RRSR''), risk factor
calibration and the raw data cleansing process; and
add detail regarding the use of ICE Clear Europe cleared
volume in the Concentration Charge threshold review.
As discussed below, the 2019 Amendments:
enhanced the calculation of the WWR threshold;
clarified the parameter estimation of the recovery rate
sensitivity requirement;
clarified the discussion around model testing;
added a section to explicitly refer to the assumption
around the use of the same time series for IM and GF distributions in
the CDS Risk Model; and provided that the interest rate sensitivity
requirement of the model reflects a time horizon of five days for house
accounts and seven days for client accounts.
With the exception of the changes to the calculation of the WWR
threshold, the amendments are in the nature of clarification and
improving descriptions of the Clearing House's existing methodology,
and do not constitute a change in the methodology. The enhancement of
the calculation of the WWR threshold, as discussed below, while a
change from prior practice, is expected to have an immaterial effect on
margin levels.
The 2019 Amendments
The following is a description in further detail of the 2019
Amendments to the CDS Risk Model.
Model Design and Development
The amendments updated the description of the interest rate
sensitivity requirement component of the IM model to add that the
changes captured in the discount default-free terms structure used for
pricing the cleared instruments are over a certain time horizon (five
days for house accounts and seven days for client accounts). This
amendment documented existing practice.
Initial Margin Methodology
With respect to IM, the amendments updated the loss given default
risk analysis to specify initial values of certain parameters and to
note that certain parameters are reviewed by the Risk Working Group on
at least a monthly basis.
With respect to the haircut applied as part of the multi-currency
portfolio treatment methodology, the amendments clarified that in order
to provide consistency and uniformity in the parameters applied to the
CDS risk model, ICE Clear Europe adopted the same (more conservative)
haircut in line with ICE Clear Credit LLC. This amendment did not
change existing practice and was intended to strengthen the IM
methodology by documenting existing practice.
Similarly, with respect to the foreign exchange haircut applied to
periodic adjustments to the GF, the amendments also clarified that in
order to provide consistency and uniformity in the parameters applied
to the CDS risk model, ICE Clear Europe adopted the same (more
conservative) haircut in line with ICE Clear Credit LLC. This amendment
also did not change existing practice and was intended to strengthen
the IM methodology by documenting existing practice.
Monte Carlo Implementation
Amendments were made to clarify and simplify the overall
description of the Monte Carlo implementation. The amendments were not
intended to reflect a change from current practice, but rather provide
a clearer description of the existing implementation. Specifically, ICE
Clear Europe believes that the revised description provides a more
practical, and less theoretical, explanation of the Monte Carlo
implementation that will facilitate replication and validation of the
implementation by third parties.
Among other clarifications, the revised description states
explicitly that the final spread response requirement would be the most
conservative requirement in the specified stress-based spread response
equation, which is consistent with current practice. Certain
subsections of the Monte Carlo description, including those relating to
the discussion of matrix decomposition, were deleted as unnecessary in
light of the description of the implemented model. The amendments
updated the copula simulation description to provide further detail as
to the determination and use of the linear correlation matrix and
construction of student-t random variables and vectors for the
production of relevant scenarios. The existing description of the
conditional block matrix simulation framework and full matrix
simulation framework were revised to provide a more simplified
description of the two-step conditional simulation approach that is
currently used by the Clearing House. A section describing copula
parameter estimation for purposes of multivariate distribution was
added while the description of simulation for standardized spread log
returns was removed as unnecessary. The model parameters section was
removed (with relevant parameters being addressed in the Parameters
Procedures as discussed below). Overall, these changes were
[[Page 13423]]
intended to more clearly reflect the current model, and would not
represent a change in methodology.
The Risk Measures section was amended to reflect existing practice
that each cleared portfolio would be initially split into sub-
portfolios based on common features in order to obtain risk estimates
reflective of the market behavior and default management practices. The
definitions of the sub-portfolios and their respective risk horizons
would be periodically reviewed by the ICE Clear Europe Risk Management
department and updated upon consultation with the Product Risk
Committee.
More detail was provided with respect to the use of simulated P/L
scenarios, combined with the post-index-decomposition positions related
to a given RF, to generate a currency-specific RF P/L vector. Each risk
factor will be attributed to only one sub portfolio and all instruments
related to a given risk factor would be denominated in the same
currency. The multi-currency risk aggregation approach will be applied
to risk factors within the European Corporate and U.S. Corporate sub-
portfolios denominated in EUR and USD currencies, respectively. A
diagram would be added to demonstrate a bivariate simulation aspect of
the risk aggregation approach. This change was intended to document
existing practices.
The Monte Carlo Engine Setups subsection and Conclusion subsection
to the Monte Carlo Implementation section were deleted for improved
clarity as content relevant to the implementation is addressed more
clearly in other sections, and the prior description of the system or
engine does not, in ICE Clear Europe's view, add useful information
beyond the other aspects of model description.
Overall, these amendments generally did not represent a change in
current operation of the MC component of the risk model.
Time Series for IM and GF Distribution
A section explaining the existing use of the same time series for
IM and GF distribution was added. The approach is designed to be
conservative and ensure that the portfolio loss at 99.75% quantile
(used for GF determination) would be always greater than 99.5% quantile
loss (used for IM determination). The approach also avoids unnecessary
operational complexity. The validity of the assumption is monitored
through the stress test impact analysis. The amendments were intended
to document existing practices and therefore were not expected to have
a material impact.
Current Amendments
The following is a description in further detail of the Current
Amendments to the CDS Risk Model.
Initial Margin Methodology
The amendments clarify the source of certain market risk transfer
activity data used in the concentration charge threshold
parameterization. The amendments also update the loss threshold
calculation in the determination of specific WWR and general WWR (to be
based on price minus recovery rate as opposed to one minus recovery
rate). Although the change makes the WWR calculation more precise, the
monetary impact on margin requirements is expected to be immaterial
(and near zero). The amendments would generally strengthen the
precision of the Initial Margin methodology based upon independent
validation findings.
The amendments would provide additional detail with respect to the
volatility floor value used in the IM methodology. The amended
description would provide that the volatility floor is estimated based
on the average overlapping five-day absolute change of recovery rates
(RRs) for a set of defaulted names. The defaulted names have a long
time series of observed RRs (i.e. more than a year) and comprise a
stress period of 2009-2012. The Clearing Risk Department would be able
to review the estimated parameters in case of the availability of
sufficient long time series of observed RRs. This is consistent with
existing practice and intended to strengthen the IM methodology by more
clearly documenting the practice.
The amendments would also clarify that with respect to the
concentration charge threshold, the market risk transfer activity data
obtained from the Depository Trust & Clearing Corporation specifically
contains both bilateral positions and ICE cleared positions. This is
consistent with existing practice and intended to strengthen the IM
methodology by more clearly documenting the practice.
Anti-Procyclicality Measures
The amendments would modify the approach to anti-procyclicality of
spread response requirements to be calibrated based on historically
observed extreme but plausible stress test scenarios in price space
defined in the revised CDS Stress Testing Policy, as discussed above,
which include various stress scenarios including the Lehman Brothers'
default and COVID-19 outbreak. This broadens the current anti-
procyclicality approach, which is based specifically on the Lehman
Brothers' default scenario. The amendments are intended to enhance the
anti-procyclicality approach to address multiple price-based scenarios
as the Lehman Brothers' default scenario alone may not be sufficient.
In particular, the amendments are intended to incorporate the Covid-19
stress scenario, in light of experience during the pandemic. Amendments
also reflect the 20% portfolio gross margin floor required under
relevant European regulation.\3\
---------------------------------------------------------------------------
\3\ European Market Infrastructure Regulation (EMIR) Article 27.
---------------------------------------------------------------------------
Monte Carlo Implementation
The amendments would clarify that in the MC implementation,
distributions are based on simulated constant maturity CDS spread
scenarios, and that instrument profits or losses are calculated by re-
pricing instruments at their coupons as well as their implied recovery
rates.
This change is intended to document existing practices.
Data
The amendments would clarify certain data fallbacks used by the
Clearing House when the normal established EOD spread data is not
available. Consistent with current practice, the amendments would
provide that if CDS spreads are not available using the usual data
sources, then the ICE Clear Europe Clearing Risk Department would use
proxy log-returns of existing clearable risk sub-factors from a similar
or correlated industry/sector. In case ICE Clear Europe rolls out risk
factors already cleared at ICE Clear Credit, the existing CDS spreads
time series would be used directly after reviewing the back-test
results. The amendments would also clarify that certain CDS spread time
series are available by risk sub-factor for the relevant benchmark
tenors.
The amendments would provide additional detail as to the
collection, analysis and back testing of relevant data for new risk
sub-factors. Pursuant to the amendments, if new risk subfactors are to
be rolled out, ICE Clear Europe would collect prices from the Clearing
Members on the benchmark tenors as per normal EOD price discovery
process before making the contracts clearing eligible. The Clearing
Risk department would be responsible for reviewing the fixed maturity
time
[[Page 13424]]
series data on the benchmark tenors until the first day of the price
collection.
The backfilling of missing data would be performed in log-return
space derived from the available EOD fixed-maturity spread levels. In
general, the 5Y tenor time series would always be available. If the
original log-returns time series presents incomplete data for less
actively traded tenors for only a few days, then interpolation/
extrapolation techniques would be applied to derive the missing data.
Once fixed maturity time series are complete, ICE Clear Europe
Clearing Risk Department would perform back-tests on hypothetical
trading strategies and stress tests on hypothetical portfolios (i.e.,
by injecting bilateral positions extracted from DTCC on the sub-risk
factor to roll out into cleared portfolios of Clearing Members) in
order to further ensure that time series for the new risk sub-factors
are appropriate to calibrate the risk models. The results of the
analyses would be presented to the CDS Product Risk Committee.
Fixed maturity time series would be transformed to constant
maturity time series (``CMTS'') to eliminate the impact of semi-annual
rolls. The amendments provide further detail as to the manner in which
CMTS series are determined and used for index and single-name risk
factors. These amendments are intended to provide further clarity to
the process as described in the Risk Model Description, but not
significantly change current Clearing House practice, consistent with
the existing Risk Model Description.
The amendments would also provide that back-testing results would
be available to assess the quality of time series as well as the
performance of the calibrated models (instead of just the latter).
Overall, these amendments relating to data are intended to better
document existing practices and therefore are not expected to change
Clearing House operation.
Testing
The Testing section would be amended to provide that tests would be
broadly grouped into the following categories: Stress tests; back-
tests; sensitivity tests; anti-procyclicality tests; and benchmarking.
The amendments are generally intended to reflect, and be consistent
with the ICE Clear Europe CDS Back-Testing Policy, CDS Clearing Stress-
Testing Policy, CDS Parameters Review Procedures and Pro-cyclicality
Framework, and further details of testing are provided in those
documents. With respect to benchmarking, as currently described in the
Risk Management Model Description, ICE Clear Europe would benchmark the
spread response model against the Model Carlo simulation approach.
Certain existing details regarding back testing of the core model
components, comparing the calibrated recovery rates used in the jump to
default requirement and actual market data, assessing whether the
assumed stress scenario adopted to size the GF is fit for purpose,
testing the liquidity component of the model, assessing measures to
mitigate the procyclicality of the margins and testing margin
sensitivity would be removed as that detail is contained in the ICE
Clear Europe Back-Testing Policy, CDS Clearing Stress-Testing Policy,
CDS Parameters Review Procedures and Pro-cyclicality Framework. The
amendments do not represent a substantive change in ICE Clear Europe's
approach to testing but are intended to clarify the Risk Model
Description and to enhance it by more clearly stating relevant
assumptions.
Other Changes Throughout the Documents
Minor typographical and drafting updates are also proposed
throughout the Documents, including updating references to Clearing
Participants (or CPs) to Clearing Members (or CMs) to be consistent
with the Rules, references to Trading Advisory Committee (or TAC) or
Trading Advisory Group (or TAG) to reflect that the TAG is not
technically a Clearing House committee, and Risk Committee to Product
Risk Committee or CDS Product Risk Committee, as appropriate, to
reflect the correct name of that existing committee.
CDS Parameters Review Procedures
ICE Clear Europe proposes to formalize certain existing practices
and procedures for calibrating and reviewing the core parameters and
underlying assumptions of its Risk Management (``RM'') model that are
not explicitly described in its CDS Risk Model Description and CDS Risk
Policy into a new Parameters Procedures document. The Parameters
Procedures thus generally are not expected to change existing Clearing
House practice.
Parameters Setting and Calibration
ICE Clear Europe's Parameters Procedures would discuss the process
of setting and reviewing the model core parameters and their underlying
assumptions. The model requirements include Spread Response (``SR'')
requirements, Jump-To-Default (``JTD'') requirements, basis risk
requirements, interest rate (``IR'') sensitivity requirements,
liquidity charge requirements, and concentration charge requirements.
Spread Response
The Parameters Procedures would describe the parameters (and
related process for reviewing and updating those parameters) that are
associated with the Spread Response components of the CDS risk model,
including as to applicability (index or single name or both), level of
granularity (e.g., risk factor), update frequency and the source of the
parameter estimations.
Time series associated with constant maturity benchmark tenors
would be analysed and the distributions that describe the fluctuations
of the benchmark tenors calibrated. The statistical parameters update
would be performed at least on a monthly basis and controlled and
managed through ICE Clear Europe internal systems.
The monitoring of the stress period selected for the scale
parameter would be performed on a monthly basis in accordance with the
CDS Risk Model Description. Proposed changes to the stress period would
be reviewed by the Clearing House's Clearing Risk Department with its
Risk Working Group and MOC.
Jump-to-Default Requirement Parameters
The parameters impacting the JTD requirement are categorized as
either LGD or WWR parameters. The Parameters Procedures would explain
how, in order to measure credit event losses, the Clearing House's Risk
Department constructs JTD scenarios in terms of anticipated recovery
rate (``RR'') levels (``RR scenarios''). The Parameters Procedures
would describe RR scenarios and estimations for corporate SNs, sectors,
and sovereign reference entities, and notes foreign exchange rate risk
considerations with respect to sovereign reference entities. The
Parameters Procedures would require ICE Clear Europe to estimate and
review the LGD parameters at least monthly and describes the associated
governance process, noting the reviewers and any prerequisites to the
implementation of parameter updates.
The Parameters Procedures would also detail the process of setting
and reviewing the WWR parameters. The Parameters Procedures would
contain information regarding the parameters that would be used to
quantify WWR dependence and to compute WWR JTD requirements.
[[Page 13425]]
Basis Risk Requirements
The Parameters Procedures would discuss how the Clearing House's
Risk Department maintains and monitors hypothetical portfolios
representing basis trades between cleared index and single-name
instruments. Basis risk is calibrated by comparing the P/Ls of such
portfolios to estimated IM requirements, excluding any concentration
charges.
Interest Rate Sensitivity Requirements
The Parameters Procedures would contain information on the
estimation and the review of the parameters that serve as inputs to the
IR sensitivity component of the risk model. The IR sensitivity
component accounts for the risk associated with changes in the default-
free discount term structure used to price CDS instruments. With
respect to the IR sensitivity requirement parameters, the Parameters
Procedures would specify how the risk department estimates the up and
down parallel shifts for the US Dollar and Euro default-free discount
term structures. The Parameters Procedures would direct ICE Clear
Europe to estimate and review the IR sensitivity requirement parameters
at least monthly.
Liquidity Charge
The Parameters Procedures would explain the process of setting and
reviewing parameters for the liquidity charge component of the risk
model. With respect to index instruments, the Parameters Procedures
would address the determination of bid/offer parameters from the
default spread width matrix and other assumptions about liquidation
cost of an index portfolio, and address procedures for review of that
matrix. The Parameters Procedures would also describe the parameters
used in determining bid/offer widths for single names, including the
use of price-based floor levels and spread-based volatility measures.
The Parameters Procedures require the Clearing House to review the
liquidity charge parameters at least monthly.
Concentration Charge
The Parameters Procedures would discuss the estimation and the
review of the concentration charge parameters, including detailing how
the Risk Department establishes series-specific or SN-specific
concentration charge threshold levels for each index or SN Risk.
Factor (``RF''), and how the Risk Department estimates
concentration charge growth rates that determine how quickly
concentration charges increase with position size. The Parameters
Procedures direct the Clearing House to estimate and review the
concentration charge parameters at least monthly.
Sensitivity Analysis
The Parameters Procedures would detail the sensitivity analyses
that the Clearing House performs to explore the sensitivity of the RM
system's outputs to certain model core parameters that are calibrated
on an ad-hoc basis and to alternative data analyses and parameter
estimation techniques. The Parameters Procedures also provide for
summary reports of relevant analyses to be provided to the Risk
Oversight Department or other relevant groups.
Portfolio Benefits Parameters
The portfolio benefits parameters control portfolio benefits during
the computation of the SR with the stress based VaR approach. The
Parameters Procedures would describe the methods for monitoring the
benefits and performing sensitivity analysis of potential parameter
changes that would reduce benefits.
Dependence Structure Shifts
The Parameters Procedures also address sensitivity analysis of
portfolio benefits implemented during the computation of the SR under
the MC simulation approach, based on different dependence structures.
The approach is intended to guide the Risk Department in situations
where back-testing results indicate excessive portfolio benefits.
SWWR Threshold Shift
The Parameters Procedures would address sensitivity analysis with
respect to model parameters that control the permitted level of index
derived SWWR, to provide guidance to the Risk Department in situations
when a decision to fully collateralize SWWR is made upon a consultation
with the Model Oversight Committee and the Product Risk Committee.
GWWR Correlation Shifts
Sensitivity analysis also considers GWWR arising from Clearing
Members exposed to Western European Sovereigns when the Kendall tau
rank-order correlation between the Member and the Sovereign entity is
above a threshold. The sensitivity analysis would be to provide
guidance to the risk departments in situations when an increase of the
dependence among members and sovereigns might lead to changes in risk
requirements.
MAD Level Shifts
The Parameters Procedures would describe sensitivity analysis on
MAD levels, which is performed by shifting all MAD estimates to their
stress levels to provide information about the response of risk
requirements to potential volatility shifts and to assess the viability
of certain parameter-setting assumptions. This sensitivity analysis
would be to provide guidance to the Risk Department about potential
risk requirement changes in stress periods due to increase in
volatility shifts.
EWMA Sensitivity Analysis
The Parameters Procedures would address sensitivity analysis
relating to the setting of the exponentially weighted moving average
(``EWMA'') decay rate (``EWMA factor''), which may affect the
procyclicality of the model.
Statutory Basis
ICE Clear Europe believes that the amendments to the Documents and
the adoption of the Parameters Procedures are consistent with the
requirements of Section 17A of the Act \4\ and the regulations
thereunder applicable to it. In particular, Section 17A(b)(3)(F) of the
Act \5\ requires, among other things, that the rules of a clearing
agency be designed to promote the prompt and accurate clearance and
settlement of securities transactions and, to the extent applicable,
derivative agreements, contracts, and transactions, the safeguarding of
securities and funds in the custody or control of the clearing agency
or for which it is responsible, and the protection of investors and the
public interest.

\5\ 15 U.S.C. 78q-1(b)(3)(F).
---------------------------------------------------------------------------
The amendments to the Documents and the adoption of the Parameters
Procedures are generally designed to enhance and clarify the
descriptions of key ICE Clear Europe risk models and documentation used
in determining CDS margin and GF requirements, particularly in the CDS
Risk Policy, CDS Risk Model Description and CDS End-of-Day Pricing
Policy. Although these changes are largely not intended to represent a
change in Clearing House practices, they should enhance the clarity and
ongoing monitoring and implementation of these policies. The amendments
also make a number of changes to the CDS Stress Testing Policy, which
are intended to add new stress scenarios relating to the COVID-19
pandemic, in light of experience in early 2020, and clarify more
generally that certain extreme scenarios should not be limited to
scenarios relating to the Lehman Brothers default. The amendments also
adopt a new set of Parameters Procedures, which is
[[Page 13426]]
intended to codify and formalize the Clearing House's approach to
setting the key parameters used in the CDS risk model, conducting
related sensitivity analyses of the impact of such parameters and
reviewing such parameters on an ongoing basis. As such, the Parameters
Procedures support ICE Clear Europe's ability to maintain sufficient
margin requirements and enhance ICE Clear Europe's approach to
identifying potential parameter changes that are appropriate to
maintain the operation of the risk model and thereby ensure that the
Clearing House continues to maintain sufficient financial resources to
withstand defaults by Clearing Members. Therefore, the amendments to
the Documents, and the adoption of the Parameters Procedures, will help
ICE Clear Europe ensure that it maintains adequate financial resources
to support its CDS operations, enhance the stability of the Clearing
House and overall promote the prompt and accurate clearance and
settlement of securities transactions and, derivative agreements,
contracts, and transactions, the safeguarding of securities and funds
in ICE Clear Europe's custody or control or for which ICE Clear Europe
is responsible, and the public interest in the sound operation of
clearing agencies. Accordingly, the amendments are consistent with the
requirements of Section 17A(b)(3)(F).\6\
---------------------------------------------------------------------------
\6\ 15 U.S.C. 78q-1(b)(3)(F).
---------------------------------------------------------------------------
For similar reasons, the amendments and the Parameters Procedures
also are consistent with relevant requirements of Rule 17Ad-22. Rule
17Ad-22(e)(3)(i) \7\ requires clearing agencies to maintain a sound
risk management framework that identifies, measures, monitors and
manages the range of risks that it faces. The various amendments
throughout the Documents as well as the new Parameters Procedures
document are all intended to clarify the operation of ICE Clear
Europe's risk management systems and provide for enhanced stress
testing. They provide greater clarity with respect to various risk
management tools, ensure that COVID-19 and other extreme but plausible
stress scenarios are accounted for and ensure current governance
practices are clearly set out, all of which facilitate ICE Clear
Europe's compliance with Rule 17Ad22(e)(3)(i).\8\

---------------------------------------------------------------------------
In addition, ICE Clear Europe believes that the adoption of the
Parameters Procedures are consistent with the relevant requirements of
Rule 17Ad-22(e)(4)(vi)(B),\9\ which requires ICE Clear Europe to
identify, measure, monitor and manage its credit exposures to
participants and those arising from its payment, clearing, and
settlement processes, including by testing the sufficiency of its total
financial resources available to meet the minimum financial resource
requirements, including by conducting a comprehensive analysis of
underlying parameters and assumptions on at least a monthly basis. The
Parameters Procedures would also provide a clear framework for ICE
Clear Europe to estimate and review the model core parameter settings
and perform and review sensitivity analyses related to certain
parameter settings on at least a monthly basis. The amendments to the
CDS Stress Testing Policy will, as discussed above, enhance the stress
testing of the Clearing House by incorporating a wider range of extreme
scenarios (including those reflecting recent market events) in stress
testing, which are reviewed on at least a monthly basis. Other
amendments would clarify how the Clearing Risk Department would address
a scenario or portfolio in the standard set of stress scenarios no
longer being applicable, or being superseded by new scenarios or
portfolios, where the Clearing Risk Department wishes to retire or
modify the outdated scenario or portfolio or add a new scenario. The
amendments serve to promote the soundness of the Clearing House's risk
management model and system and ensure that the Clearing House
possesses the ability to manage the risks associated with discharging
its responsibilities, consistent with the requirements of Rule 17Ad-
22(e)(4)(vi)(B).\10\

\9\ 17 CFR 240.17Ad-22.
\10\ 17 CFR 240.17Ad-22(e)(4)(vi)(B).
---------------------------------------------------------------------------
Rules 17Ad-22(e)(2)(i) and (v) \11\ requires that clearing agencies
provide for governance arrangements that are clear and transparent and
specify clear and direct lines of responsibility. References to the
roles of certain committees and departments with respect to reviews and
approvals throughout the Documents have been updated to better reflect
existing practice with respect to the roles of groups. Where
appropriate, references to the MRGF, which sets out further governance
details, have been added throughout the documents. The amendments
provide additional clarity with respect to Clearing House governance
and lines of responsibility consistent with Rules 17Ad-22(e)(2)(i) and
(v).\12\

\12\ 17 CFR 240.17 Ad-22(e)(2)(i) and (v).
---------------------------------------------------------------------------
Rule 17Ad-22(e)(6)(iv) \13\requires that clearing agencies cover
their credit exposures to participants by establishing a risk-based
margin system that uses reliable sources of timely price data and uses
procedures and sound valuation models for addressing circumstances in
which pricing data are not readily available or reliable. Amendments to
the CDS Model Risk Description would more clearly state the procedures
for determining relevant prices should input data not be available from
back-up sources, further strengthening ICE Clear Europe's strategies to
ensure it has access to reliable sources of timely price data in
compliance with this requirement. The amendments would also provide
further detail regarding the treatment of data collected and the
backfilling of missing data. The amendments to the CDS Risk Policy
would also strengthen the quality of intraday prices through enhanced
intraday monitoring through additional comparisons of intraday prices
with other ICE CDS clearing houses and third-party providers. Together,
the amendments strengthen ICE Clear Europe's compliance with Rule 17Ad-
22(e)(6)(iv).\14\

\14\ 17 CFR 240.17Ad-22(e)(6)(iv).
---------------------------------------------------------------------------
Rules 17Ad-22(e)(6)(i) to (iii) \15\ require that clearing agencies
establish a risk-based margin system that (i) considers, and produces
margin levels commensurate with, the risks and particular attributes of
each relevant product, portfolio, and market; (ii) marks participant
positions to market and collects margin, including variation margin or
equivalent charges if relevant, at least daily and includes the
authority and operational capacity to make intraday margin calls in
defined circumstances; and (iii) calculates margin sufficient to cover
its potential future exposure to participants in the interval between
the last margin collection and the close out of positions following a
participant default. The proposed amendments would provide more detail
regarding the IM methodology set out in the CDS Risk Policy,
facilitating the maintenance of sufficient margin levels. The CDS Risk
Policy amendments would also provide that in the event that ICE Clear
Europe is accepting sizable positions through the weekly back-loading
process in the context of margin calls, it will pre-collect IM and
mark-to-market changes, instead of just IM, to further ensure
sufficient margin collection. Amendments to the IM methodology in the
CDS Risk Model Description would
[[Page 13427]]
also enhance various aspects of the related risk analysis and related
calculations. Overall, these amendments strengthen ICE Clear Europe's
margin system and compliance with Rules 17Ad-22(e)(6)(i) to (iii).\16\

---------------------------------------------------------------------------
(B) Clearing Agency's Statement on Burden on Competition
ICE Clear Europe does not believe the proposed rule changes would
have any impact, or impose any burden, on competition not necessary or
appropriate in furtherance of the purpose of the Act. The amendments to
the Documents and the new Procedures apply to all CDS Contracts. In
general, the amendments are intended to clarify the description of the
CDS risk model, and not substantially change the practices of the
Clearing House with respect to the calculation of CDS margin and GF
requirements. As such, the amendments will apply to all CDS Clearing
Members and are unlikely, in ICE Clear Europe's view, to materially
affect the cost of clearing for CDS products or affect access to
clearing for CDS products at ICE Clear Europe or the market for cleared
services generally. Certain amendments to the CDS Stress Testing
Framework would add new stress-testing scenarios in light of recent
events, including COVID-19 related scenarios. To the extent such
amendments may have any impact on margin levels, ICE Clear Europe
believes such changes will be appropriate in furtherance of the risk
management of the Clearing House in light of the market movements
observed during the pandemic. Therefore, ICE Clear Europe does not
believe the proposed rule changes impose any burden on competition that
is inappropriate in furtherance of the purposes of the Act.
(C) Clearing Agency's Statement on Comments on the Proposed Rule Change
