I. Clearing Agency's Statement of the Terms of Substance of the 
Proposed Rule Change

    LCH SA is proposing to amend its Liquidity Risk Modelling Framework 
(the ``Framework''), which describes the Liquidity Stress Testing 
framework by which the Collateral and Liquidity Risk Management 
department (``CaLM'') of LCH SA assures that LCH SA has enough cash 
available to meet any financial obligations, both expected and 
unexpected, that may arise over the liquidation period for each of the 
clearing services that LCH SA offers (the ``Proposed Rule Change'').\3\ 
The text of the Proposed Rule Change is provided in Exhibit 5 [SIC].\4\ 
The implementation of the Proposed Rule Change will be contingent on 
LCH SA's receipt of all necessary regulatory approvals.
---------------------------------------------------------------------------

    \3\ LCH SA, a subsidiary of LCH Group and an indirect subsidiary 
of the London Stock Exchange Group plc (``LSEG''), manages its 
liquidity risk pursuant to, among other policies and procedures, the 
Group Liquidity Risk Policy and the Group Liquidity Plan applicable 
to each entity within LCH Group. In addition to its CDSClear 
service, LCH SA provides clearing services in connection with cash 
equities and derivatives listed for trading on Euronext 
(EquityClear), commodity derivatives listed for trading on Euronext 
(CommodityClear), and tri-party Repo transactions (RepoClear). LCH 
SA also maintains an interoperability link with Euronext Clearing, 
formerly Cassa di Compensazione e Garanzia, in Milan, Italy.
    \4\ All capitalized terms not defined herein have the same 
definition as in the Framework, unless otherwise stated.
---------------------------------------------------------------------------

II. Clearing Agency's Statement of the Purpose of, and Statutory Basis 
for, the Proposed Rule Change

    In its filing with the Commission, LCH SA 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. LCH SA 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

1. Purpose
    The Proposed Rule Change is being adopted to (1) enhance details 
about how LCH SA models for the liquidity needs arising from the daily 
settlement process in its RepoClear service related to the auto-
collateralization feature in its Framework, (2) amend how LCH SA 
accounts for non-defaulting members' excess collateral in the 
calculation of the Standalone Operational Target and Liquidity Coverage 
Ratio (``LCR'') in its Framework, (3) quantify LCH SA's liquidity needs 
arising from clearing members replacing liquid resources with non-
liquid resources for liquidity needs modelling, (4) clarify how LCH SA 
accounts for clearing members switching their respective pledging 
arrangement for collateral included in LCH SA's Standalone Operational 
Target and (5) enhance the Framework to simulate a sovereign country 
rating downgrade when computing liquidity reverse stress tests. LCH SA 
is proposing to make other non-substantive changes to correct errors 
and for purposes of conformity.

[[Page 16904]]

Section 1.6.1--Liquidity Sources
    LCH SA is amending Section 1.6.1 by removing reference to cross-
currency bilateral repo that involved a bilateral repo and an FX 
transaction (whereby LCH SA may pledge collateral denominated in one 
currency for cash denominated in a different currency as a liquidity 
resource to meet its liquidity resource requirement). LCH SA is making 
this change because it currently only uses triparty repo to perform 
cross-currency transactions under which the FX conversion is managed by 
the triparty agent. This amendment will also align the Framework with 
the LCH SA Liquidity Plan (the ``Liquidity Plan''). The same change 
will be reflected in Appendix 6.5: ``Liquidity risk monitoring 
reports'' for consistency as well as to conform with Section 1.6.1.3.
    LCH SA is also replacing reference to ``FX spot market 
transaction'' with ``FX operation'', which LCH SA believes more 
accurately reflects the process. Finally, LCH SA is clarifying that 
there is no multicurrency committed lines anymore given the removal of 
the reference to the Norges bank secured committed facility. Therefore, 
only an uncommitted overdraft facility with an international bank 
remains in place.
Section 1.6.1.1--Collateral Transfer to 3G Pool
    LCH SA is proposing an amendment to remove reference to 
``successfully tested in 2016'' to clarify that the operational 
effectiveness of the transfer of collateral to the 3G pool is tested on 
an annual basis as part of the war games exercises (i.e., instead of 
having a singular reference to 2016).
Section 1.6.1.3--Synthesis
    LCH SA is proposing to amend the summary table in Section 1.6.1.3 
to align with the changes made to the preceding paragraphs. 
Specifically, reference to cross-currency bilateral repo transactions 
will be removed because LCH SA no longer utilizes these transactions to 
raise liquidity sources, and instead leverages cross currency triparty 
repo transactions. Moreover, the reference to FX transactions will be 
removed because the triparty cross currency repo transactions do not 
entail FX transactions, and instead, the FX conversion is managed by 
the triparty agent. LCH SA is also proposing to clarify that CaLM will 
demonstrate to the Board these prearranged funding arrangements used to 
raise euro liquidity are highly reliable even in extreme but plausible 
market conditions, as part of the annual review of the Liquidity Plan. 
In making this change, LCH SA is removing the historical reference to 
liquidity resources raised to meet its requirements in 2021 and 2022, 
as this reference is outdated and no longer applicable. For securities 
received from triparty reverse repo transactions where the agent is 
Clearstream as a Central Securities Depository, LCH SA is specifying 
that such securities are not considered Liquid Resources because LCH SA 
does not have the right to rehypothecate these securities for purposes 
of raising liquidity. This updated text will substitute the previous 
historical reference to the Clearstream triparty repo facility and its 
exclusion from liquid resources, as LCH SA has not completed the 
technical setup needed to rehypothecate such securities. LCH SA also 
proposes to clarify that collateral ineligible to be pledged to the ECB 
to raise liquidity via triparty repo transaction refers to USD- (U.S. 
Treasuries) and GBP-denominated securities (UK Gilts) only. LCH SA is 
also removing reference to a secured committed credit line with Norges 
Bank as an available liquidity resource, as this facility is no longer 
in place. Since LCH SA has access to an uncommitted credit line with an 
international bank to cover overdrafts up to [euro]10mm, LCH SA is 
clarifying that this resource is uncommitted, given removal of the 
reference to the Norges bank secured committed facility. LCH SA will 
also amend Section 6.3: Appendix 3 and Section 6.5: Appendix 5 to 
reflect the removal of the Norges Bank facility for purposes of 
conforming throughout the Framework.
Section 1.6.2.3: Operational Liquidity Requirements
    In Section 1.6.2, LCH SA describes the three main sources of 
liquidity needs for the clearing agency as those arising from member 
defaults, liquidity needs arising from interoperating CCP defaults and 
needs related to operational liquidity requirements. With respect to 
operational liquidity needs, LCH SA is proposing to clarify in Section 
1.6.2.3 that a need may arise from the substitution of liquid resources 
to non-liquid resources upon member request. The previous reference to 
substitution of cash collateral by members was incomplete as all liquid 
resources could be considered as a need if switched to non-liquid 
resources. As part of this revision, LCH SA is removing reference to 
the need arising from an increase in Central Bank Guarantee (``CBG'') 
payments because there is no dual payment solution for members using 
the CBG solution and therefore no possibility to switch to another 
available regime of collateral if the CBG solution is used by a 
counterparty. Finally, LCH SA is adding the liquidity need arising from 
clearing members switching to a pledge regime (i.e., from FTT to 
pledge) for collateral posted as margin. Collateral posted under the 
pledge regime is not considered a component of liquid resources, but 
rather an operational liquidity need, given that LCH SA does not have 
rehypothecation rights to such collateral unless the member posting it 
is in default.
Section 1.6.2.4: Zoom on the Settlement, its Benefits and Issues (Auto-
Collateralization Feature)
    As part of its daily settlement process, LCH SA has the ability to 
leverage the auto-collateralization feature for certain ECB-eligible 
securities as part of the ECB's T2S service for securities settlement. 
The ECB's T2S auto-collateralization service enables LCH SA to 
facilitate timely settlement of a RepoClear transaction in the event of 
a timing mismatch between the security delivery and the cash delivery 
in the settlement platform. Specifically, should a seller deliver ECB-
eligible securities before delivery of cash by the buyer, the T2S auto-
collateralization service will allow LCH SA to pledge these securities 
for cash at the applicable central security depository (``CSD''). LCH 
SA is therefore able to settle the seller instructions against the 
pledge of these securities as collateral for the liquidity borrowed 
from the T2S service.
    If LCH SA is not able to find a legitimate buyer for delivering the 
securities within the end of day and to avoid any fees chargeable to 
LCH SA for securities pledged overnight, LCH SA must inject the full 
cash equivalent amount to release the securities from the auto-
collateralization account and subsequently transfer these securities 
from the CSD to the BdF 3G Pool. In doing so, LCH SA can obtain 
liquidity from the BdF after adjusting for any applicable haircuts. LCH 
SA quantifies the liquidity need arising from this transaction by 
multiplying a pre-defined auto-collateralization limit set by the CCP 
for each Dedicated Cash Account (``DCA''), corresponding to a pool of 
securities in the settlement platform, by an applicable ECB haircut for 
each sovereign debt type. For the case in which multiple issuers are 
assigned to the same DCA, the auto-collateralization limit is set pro 
rata for each issuer based on the average daily settlement percentage 
from the previous year. LCH SA takes the sum of the results of

[[Page 16905]]

potential liquidity impact for each sovereign debt issuer and reduces 
by this total the assets in the numerator of the LCR, as well as the 
resources to be compared against the Operational Target. All else being 
equal, an increase in any one of these parameters will result in a 
decrease in the LCR and Operational Target Key Risk Indicator (``KRI'') 
and vice versa.
    The current Framework therefore computes the auto-collateralization 
liquidity need by leveraging the specific limits set up in production 
and approved by LCH SA's Second Line Risk function and LCH SA 
management, in addition to utilizing the current ECB haircut schedule. 
The ECB assigns haircuts based on several parameters, including the 
type and issuer of the debt instrument, the residual maturity and 
overall credit quality. For example, the ECB as of August 2024 applies 
a larger haircut to sovereign debt issued by Italy compared with France 
for the same residual maturity due to the overall credit quality 
difference, among other factors. For Italy, Germany, Spain and Belgium, 
the current Framework applies 100% haircut for conservative reasons 
because the operational effectiveness of the ``bulk'' transfer from T2S 
to the 3G Pool was only recently demonstrated via a conclusive test in 
June 2024.
    LCH SA is proposing to amend Section 1.6.2.4 of the Framework to 
provide additional clarification on the auto-collateralization feature 
that was not explicit in the current version of the Framework. 
Currently, the Framework lacks detail with respect to the auto-
collateralization feature, including the operational steps by which LCH 
SA would utilize the feature. As such, LCH SA is proposing to add a 
paragraph describing the auto-collateralization feature, including how 
LCH SA will use it in the event a buyer does not deliver cash for 
delivered securities. This Section will also be amended to specify the 
three core steps involved should LCH SA utilize the auto-
collateralization feature. The first step includes injecting the full 
amount of liquidity to unlock the pledged securities. Step two includes 
transferring the securities from the CSD to the 3G Pool and step three 
includes obtaining liquidity through the 3G Pool, after applying 
applicable ECB haircuts. LCH SA is also clarifying that because of the 
aforementioned steps, the maximum potential liquidity drain will be 
equal to the ECB haircut for each debt type applied by the BdF when the 
securities withdrawn from the settlement system are then pledged to the 
3G Pool to source liquidity.
    LCH SA is proposing to remove the following sentence because of the 
inclusion of the detailed steps describing the auto-collateralization 
functionality:

that enables to obtain the liquidity necessary to the finalisation 
of transactions by pledging the security underlying the transaction 
at the BdF to get cash.

    LCH SA is also clarifying that the maximum potential liquidity 
drain is modeled based on three elements: (1) the operational 
effectiveness and readiness of the transfer of securities from T2S to 
the 3G Pool for each issuer, as demonstrated on an annual basis through 
LCH SA's War Games exercises that are validated in governance; (2) 
actual limits for each debt type as defined in production and 
appropriately validated by all relevant stakeholders and Second Line 
Risk prior to any update as defined in a dedicated internal procedure; 
and (3) the current most conservative ECB haircut of the relevant debt 
category and step actually in force at the moment of the monitoring. 
With respect to the first element, LCH SA is clarifying that, in the 
event LCH SA is unable to effectively demonstrate the effective 
transfer of securities to the 3G Pool to source central bank liquidity 
as part of its War Games exercises, the haircut applied to the impacted 
issuer will be set at 100% and the corresponding liquidity need 
modelled will be equal to the full amount to be injected to reimburse 
the auto-collateral credit at end of day. LCH SA is also amending 
Section 6.5 (Appendix 5: Liquidity Risk Monitoring Reports) to provide 
an example intraday liquidity report that will be used to monitor for 
purposes of the second element referenced above. The previous report is 
therefore deleted as not accurate anymore. In addition, LCH SA is 
specifying that any changes to the ECB haircuts considered by the model 
or the auto-collateralization limits will be automatically reflected in 
the Framework modelling. LCH SA is also specifying that in the case of 
a distinct ECB category and haircut step and/or different operational 
readiness to transfer securities in bulk from T2S to the 3G Pool 
between different issuers assigned to the same DCA, the allocated 
portion of the limit to each issuer will be defined based on the 
average daily settlement obligation per security over the last year for 
purposes of computing the liquidity impact.
    LCH SA is also proposing to delete the table reflecting the limits 
by settlement platform and activity as of March 30, 2022, and the 
associated footnotes. This table and related footnotes are primarily 
being removed because LCH SA will instead apply a more dynamic approach 
to determining the maximum liquidity drain that could occur by 
following the steps referenced above. An example of liquidity reporting 
is provided in Appendix 6.5 for informational purposes only and 
specifying that the model may utilize updated figures (to be defined in 
accordance with the specifications outlined in Section 1.6.2.4). The 
reference to applying an 11% haircut to ECB securities is being 
removed, as LCH SA will instead apply the current most conservative ECB 
haircut of the relevant category and step. LCH SA is also proposing to 
delete reference to the specific previous War Games exercises performed 
to demonstrate operational effectiveness for purposes of pledging 
securities to the 3G Pool in 2019 and 2021. This reference is now 
covered by the first element specified above regarding how LCH SA will 
determine operational effectiveness and readiness for issuers moving 
forward (i.e., through its War Games exercises performed each year).
    Collectively, these changes to the auto-collateralization feature 
described in the Framework do not directly impact the Framework 
methodology for calculating the LCR or the Operational Target. The 
respective formulas will remain the same, but instead when 
incorporating the liquidity need deriving from the auto-collateral 
functionality, the formulas will utilize dynamic input data (rather 
than static values defined in the LRMF), such as the most recent ECB 
haircuts and the actual auto-collateralization limits set up in 
production at the time of monitoring and according with the specific 
methodology described above. The purpose of the revisions to Section 
1.6.2.4 is to enhance the clarity of the Framework by describing more 
explicitly the general steps considered by the CCP when modelling the 
potential liquidity need arising from the auto-collateralization 
functionality in the settlement platforms.
Section 4.1.2: Model Inputs and Variable Selection
    As part of determining its overall liquidity needs on an ongoing 
basis, LCH SA models for its operational liquidity needs as part of the 
Framework. The operational liquidity requirement is valued through the 
Operational Target in the daily liquidity stress tests. The requirement 
represents the amount of liquidity required to satisfy the liquidity 
needs borne from the ongoing operational management of LCH SA in a 
stressed environment. This

[[Page 16906]]

requirement is therefore not related to a clearing member default. LCH 
SA specifies this liquidity requirement drivers it models in the 
Framework in Section 4.1.2. LCH SA is proposing to amend certain 
provisions of this Section by revising the statement related to the 
repayment of excess cash and excess ECB-eligible securities posted by 
members as a liquidity need to state the ``partial'' repayment of 
excess. As part of the Proposed Rule Change, LCH SA is adjusting how it 
models for the treatment of excess collateral and this change is being 
made to align for the revised treatment of excess collateral throughout 
the Framework (see Section 4.1.5 below). The clarification of liquid 
resources-eligible securities is being made to reflect that a liquidity 
need arises from the withdrawal of liquidity resources and thus the 
reduction in available liquidity. An amendment to note 16 is also being 
made to clarify that non-euro cash and CBGs are excluded as liquidity 
resources because LCH SA does not consider USD and GBP cash posted by 
members as liquid resources for conservative reasons, and for CBG, LCH 
SA does not have the ability to use such assets for liquidity purposes 
unless such member is in default. To align with the clarification made 
regarding liquidity needs that may arise from clearing member 
substitution of liquid resources to non-liquid resources (see the 
proposed changes to Section 4.1.5.(e) below), LCH SA is amending 
Section 4.1.2(e) to clarify that the substitution refers to liquid 
resources (not just cash or ECB-eligible collateral) to non-liquid 
resources.
    Moreover, a new liquidity need in Section 4.1.2(j) is being added 
to specify that in the calculation of the Operational Target there will 
be a provision to model the switch from collateral posted under FTT, 
and therefore included in liquid resources, to collateral posted under 
the pledge regime, and therefore considered as non-liquid resources if 
the member posting the collateral is not in default. This conforms with 
the change made to Section 1.6.2.3.
Section 4.1.4: Mathematical Formula, Derivation and Algorithm, and 
Numerical Approximation
    Finally, to conform with the changes made to Section 1.6.2.3, LCH 
SA will add as a liquidity requirement captured in the Framework (as 
Section 4.1.2(j)), the switch from collateral posted under FTT to the 
pledge regime. Because of the addition of the needs arising from the 
switch from FTT to pledge, LCH SA will add to Section 4.1.4 the needs 
arising from the switch as an input to the Operational Liquidity 
Requirements. Specifically, LCH SA's Operational Liquidity Requirements 
now comprise all items referenced in Section 4.1.2 (including Section 
4.1.2(j)).
Section 4.1.5: Model Assumptions (Treatment of Excess Collateral)
    LCH SA is also proposing to amend how it models for the treatment 
of excess collateral of non-defaulting clearing members in its 
Operational Target calculation of the Framework. Currently under LCH 
SA's cover 2 Framework, LCH SA considers that in a default, non-
defaulting members will withdraw all their excess collateral following 
a stress event. In contrast, excess collateral is considered a 
liquidity resource for defaulting members.
    LCH SA is proposing to modify the assumption that all excess 
collateral is withdrawn immediately following a stress event in its 
Framework. Specifically, LCH SA would like to revise the assumption 
that all excess collateral will be withdrawn following the declaration 
of default in the LCR or during the non-default market stress scenario 
of the Operational Target standalone calculation. This proposed change 
would refine the Framework by more closely aligning it with current 
clearing member behaviors and with the appropriate liquidity horizon 
period (currently modeled at seven days), while at the same time 
maintaining a conservative assumption. To facilitate this change, LCH 
SA is proposing to model for a partial withdrawal of excess collateral 
based on an indicator calibrated with empirical clearing member data. 
The partial withdrawal will be based on the second worst observed 
relative variation experienced over seven days, capped at the biggest 
historical reduction in excess collateral over the liquidity horizon, 
utilizing up to ten years of historical data, initiating in 2018.
    The rationale for considering the second highest observed 
historical relative excess decrease is that it represents a confidence 
level of 99.9% related to a stress event compared to the standard 99.7% 
used for margin computation in LCH SA. Moreover, as the value will be 
automatically integrated in the daily Operation Target as part of a 
dedicated monitoring, it allows ample time for LCH SA's Second Line 
Risk team to investigate any data issues or any data outliers without 
an immediate direct impact on production.
    LCH SA is proposing to calibrate this indicator daily, thereby 
incorporating each new daily data point. In order to be consistent with 
the Framework, LCH SA is also proposing to align the withdrawal over a 
seven-day period (i.e., the liquidity horizon), rather than the current 
three-day period. Finally, LCH SA is proposing to implement an 
enhancement of the daily back testing, specific to this change, to 
ensure any changes in the partial withdrawal scenario are flagged to 
senior management. Any new extreme (i.e., second biggest seven days 
relative margin reduction or seven days biggest absolute cap amount) 
will automatically be integrated in the Framework the following day and 
will be shared with the Head of Market Risk and the Chief Risk Officer. 
In addition, a deep analysis will be performed to assess the level of 
excess reduction modelled each intermediary day of the liquidity 
horizon considering the drivers of the new peak. Results of this 
exercise may lead to a review of the split of excess collateral 
reduction modelled in the intermediary days within the liquidity 
horizon and any change to the Framework would therefore require review 
and approval by the ERCo.
    To reflect this methodological change in the Framework, LCH SA is 
proposing to amend Section 4.1.5(d) by clarifying the description of 
how the withdrawal of excess collateral is modelled. Specifically, LCH 
SA is proposing to state that a portion of excess collateral is 
withdrawn over the seven-day liquidity horizon period, with the target 
estimated excess collateral amount assessed based on historical data 
dating back to 2018. LCH SA is also proposing to specify that the 
calibration of this amount will be updated daily as new data becomes 
available and up to a ten-year lookback period. As part of this change, 
Section 4.1.5 will also be amended to add that the relative reduction 
in excess collateral will correspond to the second worst observed 
relative decrease of excess collateral over a seven-day period, with a 
cap of the highest absolute reduction amount observed over seven days. 
LCH SA will provide additional details in Section 4.1.5 in the form of 
a specific formula as well as the list of assumptions made to clarify 
how the reduction in excess collateral will be applied. Previous 
references to the assumptions of excess collateral withdrawal on day T, 
day T+1 and day T+2 will be removed and replaced with the following 
clarifications:
    <bullet> The overall compounded excess reduction over the liquidity 
horizon will correspond to the second worst relative rate observed over 
seven days excess reduction, over the calibration period capped at the 
highest absolute reduction amount observed;

[[Page 16907]]

    <bullet> The biggest reduction relative rate observed on a single 
day will be applied the first day;
    <bullet> In each intermediary day, the compounded excess reduction 
is above the 99.7% percentile confidence interval within the historical 
window observed;
    <bullet> LCH SA assumes that it will not observe any increase of 
excess from members over the liquidity horizon; and
    <bullet> The assumptions will be monitored daily, such that if a 
new second worst relative rate is observed, it will automatically be 
reflected in the computation of the metric.
    LCH SA is also proposing to amend note 18 to add that, in addition 
to DKK, NOK, SEC, AUD, CAD, CHF and JPY securities, collateral 
belonging to FCM/BD clients and Portuguese and Finnish securities 
deposited through a triparty arrangement are excluded from liquidity 
assets in excess collateral. LCH SA will also exclude non-euro cash and 
CBGs. This last change is being made for purposes of accuracy and does 
not represent a change in the methodology of the Framework or 
procedures of LCH SA.
    Also, a new note 19 will be added to reference the member 
behavioral analysis documented in Section 6.2 ``Appendix 2''. Section 
6.2 will be revised to clarify and provide additional evidence about 
the methodology detailed in Section 4.1.5. Specifically, in the bullet 
points summarizing the risk drivers, the phrase ``Excess withdrawn'' 
will be replaced by the phrase ``Partial excess withdrawal'' for 
purposes of clarity and to conform with similar changes made to the 
Framework.
    Moreover, LCH SA is proposing to state it will assume that a 
portion of the amount of excess collateral will be withdrawn over seven 
days and this will substitute the current wording that states that the 
full amount is assumed to be withdrawn over three days. Moreover, the 
excess reduction will be based on the second worst relative downward 
reduction of excess, capped to an absolute amount corresponding to the 
highest absolute reduction amount observed in the lookback period. To 
support the change, LCH SA is proposing to add an example of how the 
intermediary daily excess reductions are modelled by the proposed 
methodology and included in a table reflecting the margin reduction 
rate, the cumulative reduction and the absolute value of the capped 
amount over each day of the seven-day period. LCH SA will also clarify 
that the figures presented in the example table are for informational 
purposes only and that the current model will utilize the most recent 
figures in accordance with Section 4.1.5.
    LCH SA is also proposing to make a small amendment to Section 6.3 
``Appendix 3: Reminder of SA's sources of liquidity and related risk 
drivers'' with respect to excess collateral. That is, LCH SA is 
proposing to create a new category '' Excess Collateral'' and to state 
that the source of liquidity considered is the excess posted by member 
and add the text ``Partial withdrawal of excess.'' LCH SA is further 
removing the specific reference to excess cash collateral, as the 
proposed wording is more aligned to the methodology presented in 
Section 4.1.5(d). LCH SA is also proposing to amend Section 6.4 ``6.4 
Appendix 4: Liquidity risk drivers synthesis by reports''. 
Specifically, the column labelled ``Excess'' under ``BAU'' will be 
amended to reflect that instead of 100 percent of excess collateral 
being withdrawn, LCH SA will utilize the second worst relative withdraw 
of excess collateral capped at the highest reduction amount observed, 
for each Operational Target, LCR Cover 2 for non-defaulting members and 
LCR Euronext Clearing. Changes to Sections 6.3 and 6.4 will be made to 
align with the changes made to Section 4.1.5.
    To accurately account for the switch of liquid resources to non-
liquid resources in the assumptions of the Framework, LCH SA is 
proposing to amend Section 4.1.5(e) to include details on the new 
proposed calculation and underlying assumptions. To align with changes 
performed in 4.1.2, LCH SA clarifies that the substitution refers to 
liquid resources (and not only cash or ECB-eligible collateral as 
reported in the header of the section 4.1.5(e) in the previous version 
of the Framework) to non-liquid resources. The result of the 
calculation represents the target estimated switch over a liquidity 
horizon of seven days and is based on historical data calibrated daily. 
LCH SA is proposing to build the time series of data utilized in the 
calculation until it reaches a maximum lookback period of 10 years 
(beginning in 2022). This revision also corresponds to the extension of 
the offering of securities in DKK, NOK, SEK, CAD, AUD, JPY, and CHF as 
eligible collateral. LCH SA is proposing a conservative assumption to 
this calculation by assuming clearing members will not switch non-
liquid collateral with liquid collateral over the liquidity horizon and 
by applying the largest absolute net substitution amount historically 
observed on a single day over the lookback period, on the first day of 
the liquidity horizon. For each subsequent day, the compounded net 
substitution amount will be set above the 99.7% percentile confidence 
interval within the historical window observed. LCH SA will choose the 
overall compounded switch value over the liquidity horizon that 
corresponds to the second worst absolute observed seven-day 
substitution over the period (the ``net substitution amount''). The net 
substitution amount is calculated for each date and collateral account 
and is based on a multi-step process that includes the calculation of 
two metrics: a negative substitution amount, or an amount that reflects 
a clearing member switching liquid resources with non-liquid resources, 
and a positive substitution amount, or an amount that reflects a 
clearing member switching from non-liquid to liquid resources. The net 
substitution amount represents the difference between the negative 
substitution amount and the positive substitution amount. LCH SA 
chooses the aggregate cumulative sum over each day of the liquidity 
horizon. Consequently, all the references to the former methodology and 
the related assumptions are proposed to be removed as the substitution 
is not performed anymore on the maximum historical substitution 
observed over the last 7 days. To complement this proposed change, LCH 
SA is adding in Appendix 6.2 (``Members Behaviour Analysis'') an 
illustrative example of the cumulative switch amounts from liquid 
resources to non-liquid resources over the seven-day liquidity horizon 
and reference in a new note 20. LCH SA will also clarify that the 
figures presented in the example table are for informational purposes 
only and that the current model will utilize the most recent figures in 
accordance with Section 4.1.5. The updated text replaces the previous 
paragraph in the previous version of the Framework that described the 
substitution methodology and gave an overall description of LCH SA's 
collateral composition and in particular the split between the ECB 
eligible EUR non cash collateral and non EUR collateral, which is now 
outdated as the collateral composition is a function of members' 
activity and the proposed new methodology adequately captures it more 
dynamically. In addition, the reference to reverse stress test results 
and concentration limits applied on non-cash collateral is being 
removed as this reference is no longer relevant for the description of 
the new methodology, as it calibrates substitution amount on the basis 
of actual data observed over the lookback period. For the purpose of 
providing accuracy, the first bullet point in Appendix 6.2, where the 
risks driven

[[Page 16908]]

are summarized as ``Substitution cash to non cash (Banks keeping their 
cash)'' will be replaced by ``Substitution from Liquid Resources to 
non-Liquid Resources''.
    For the avoidance of doubt, LCH SA is also clarifying in Section 
4.1.5(e) that the assumptions underlying the calculation of the switch 
amount will be monitored daily and compared against the parameters set 
up in production according to the described methodology with new 
extrema automatically reflected in metric calculations (amounts 
presented in Appendix 2 represent minimum values and may therefore 
fluctuate daily). Moreover, LCH SA is specifying that the net 
substitution amount is determined using allocated collateral. To 
enhance the clarity of the Framework, note 21 will be added to specify 
which collateral type is excluded from the computation of the 
substitution quantity, either because it is already considered in 
different provisions of the Framework, or because the substitution from 
Liquid Resources to non-Liquid Resources is not possible for the 
specific collateral type.
    LCH SA is also proposing to amend Section 6.4 ``6.4 Appendix 4: 
Liquidity risk drivers synthesis by reports''. Specifically, the column 
labelled ``Substitution'' under ``BAU'' will be amended to align with 
Section 4.1.5(e) by reflecting that the Operational Target, the LCR 
Cover 2 and the LCR Euronext Clearing will all consider partial 
substitution to non-Liquid resources equal to the second worst 
substitution historically observed.
    In addition, in Section 4.1.5(e), LCH SA is proposing to clarify 
that ECB eligible securities can be pledged to the central bank within 
the same day and the readiness must be tested and validated annually as 
part of the Liquidity Plan. That is, LCH SA will demonstrate its 
ability to perform the necessary activities for purposes of meeting its 
regulatory obligations related to ensuring access to liquidity. 
Furthermore, the new language replaces the current reference to War 
Games Q3 2022 results, given these results are outdated.
    Finally, the previously applied methodology for tracking asset 
switches from cash or ECB eligible securities to non-euro securities, 
equity lodging, and the use of central bank guarantees are no longer 
relevant and have been removed. These methodologies, which relied on 
observed maximum daily switches over a seven-day period, conservative 
equity lodging and the specific assumption about CBG usage are outdated 
and not relevant anymore. Instead, a more comprehensive and holistic 
methodology has been introduced as described above to ensure a more 
accurate and dynamic approach to liquidity management.
    Section 4.1.5(g) is being modified to specify that in alignment 
with Sections 4.1.5(d) and 4.1.5(e) the assumptions used to estimate 
the margin reduction in the Operational Target are monitored daily and 
in case of new extreme, this will be automatically reflected in the 
computation of the metric. Moreover, note 24 is being modified to state 
that the lookback used to calibrate the assumption of margin reduction 
does not end in 2022 because it is instead updated daily. The same 
amendment will be reflected in Appendix 6.2 (``Members Behaviour 
Analysis''), with the addition of the sentence specifying that the 
numbers reported in the example (which reflect the split on each day of 
the margin reduction) are provided for informational purposes only and 
that the model may utilize updated figures, which will be defined in 
accordance with the specifications outlined in Section 4.1.5(g). A new 
Section 4.1.5(j) is being added to provide details on how LCH SA models 
for the scenario where clearing members switch the regime of how 
collateral is posted to the clearing agency (i.e., FTT to pledge). The 
Framework will model this behavior by comparing the second biggest 
historical pledged amount observed over a 10-year lookback period with 
the actual observed pledge collateral amount starting in 2022. The 
difference between these two components will correspond to the amount 
LCH SA will include in its daily liquidity requirements and is above 
the 99.7% percentile. Like the calculation for the switch from liquid 
to non-liquid resources, LCH SA will implement additional daily 
monitoring and recalibrate the calculation of this metric as necessary 
if a new maximum is observed.
    In Appendix 6.2 (``Members Behaviour Analysis''), LCH SA will add 
the bullet ``Substitution to pledge regime'' among the list of the risk 
drivers and will conform with Section 4.1.5(j), such that the provision 
will be equivalent to the difference between the second biggest 
historical amount of pledge observed and the actual observed pledge 
collateral amount.
    LCH SA will also amend the risk mitigation measure referenced in 
Section 6.3: Appendix 3 as it pertains to pledged securities as 
collateral. Specifically, LCH SA will clarify that the risk related to 
clearing members moving away from FTT in favor of the pledge regime is 
accounted for in the modelling of the LCR and the Standalone 
Operational Target. This element is not a change in the current 
practice with respect to the LCR computation but an alignment with the 
introduction of the modelling of the switch from FTT to the Pledge 
regime in 4.1.5(j).
    LCH SA is also proposing to amend Section 6.4 ``6.4 Appendix 4: 
Liquidity risk drivers synthesis by reports''. Specifically, the column 
labelled ``Substitution'' under ``BAU'' will be amended to reflect that 
for the Operational Target, a provision to model the switch to the 
pledge regime according to Section 4.1.5(j) will be included, while for 
the LCR Cover 2 and LCR Euronext Clearing calculations, the pledge 
collateral will be set to the maximum limit allowed as described in 
Section 4.2.5.2.4 of the Framework. Language indicating the 
substitution would be the historical max including an increase of CBG 
payments would be deleted from each of these rows to reflect the 
different changes performed in section 4.1.5.(e) and (j) and the 
methodology described in Section 4.2.5.2.4 of the Framework. The 
reference to Central Bank Guarantee is outdated and not relevant 
anymore and it is replaced by the updated methodology described herein. 
For clarify, LCH SA notes that contrary to the LCR, the Standalone 
Operational Target assumptions do not imply clearing member defaults, 
thus justifying the difference of modelling the pledge regime.
Section 4.2.5.2.1: Operational Target (Considered in LCR Cover 2)
    The LCR assumes the default of the biggest 2 groups in term of 
liquidity while the Standalone Operational Target assumes a market 
stress event not leading to a default. Therefore, when integrating the 
Standalone Operational Target into the computation of the LCR, it is 
adjusted to be more conservative and align with different assumptions 
taken in the LCR. LCH SA is proposing to make certain clarifying 
changes with respect to how the Standalone Operational Target is 
calculated for its LCR under a cover 2 approach. LCH SA will substitute 
the text ``Repayment of Excess cash posted by members'' with 
``Repayment of Excess posted by members'' to align with what is 
described in section 4.1.5(d). Moreover, LCH SA is clarifying that it 
will utilize a more conservative assumption regarding how it models for 
the switch from FTT to pledge, whereby the pledged collateral will be 
set to the maximum limit allowed as described in Section 4.2.5.2.4 of 
the Framework.

[[Page 16909]]

    LCH SA will make a conforming change in Section 4.3.5.4 related to 
the Standalone Operational Target in the LCR calculation for a Euronext 
Clearing default to align with this change of Section 4.2.5.2.1, as the 
described change applies to both LCR cover 2 and LCR Euronext Clearing.
    In addition, the sentence: ``The margin outflows calculated in the 
operational target and related to the cover 2 is removed for LCR since 
the CCP will fully use the collateral of the defaulters'' will be 
reworded to ``The margin outflows calculated in the operational target 
and related to the cover 2 is removed from LCR liabilities since the 
CCP will fully use the collateral of the defaulters''. This change is 
being made to add more clarity regarding how LCH SA calculates LCR 
liabilities.
    In Section 4.3.2: ``Model inputs and Variable selection'' (related 
to LCR Euronext Clearing), LCH SA will correct a typo and revise the 
previous name of the interoperable CCP, ``CC&G'' to the current name, 
``Euronext Clearing''.
Section 5.3.1: Independent Stress of Various Risk Factors
    As part of its ongoing monitoring of the Framework, LCH SA performs 
independent reverse stress tests for certain risk factors that could 
result in a liquidity shortfall. One of these independent reverse 
stress tests involves a Eurozone downgrade of peripheral and core 
countries that triggers an increase in ECB haircuts, whereby the value 
of liquidity resources decreases by an amount resulting in a liquidity 
deficit. LCH SA is proposing to review the assumptions underpinning the 
stress scenario by noting that the simulated downgrade will be based on 
the maximum simultaneous downgrade notches that occurred over seven 
days for each of the four rating agencies acknowledged by the ECB, 
aggregated per type of debt (i.e., Core/Peripheral). After computing 
the downgraded rating, LCH SA will use the rules defined by the central 
bank to assign each issuer a haircut category and a haircut step in 
order to apply the parameter aligned with the updated rating with a cap 
to step 3 (which is considered the most conservative haircut category 
applied by the ECB before collateral becomes ineligible for pledge). 
LCH SA notes that because of the historical measures taken by ECB 
during stressed periods (e.g., Eurozone crisis) and the high quality of 
non-cash collateral, the ineligibility of issuers to pledge to the ECB 
is not considered a plausible scenario. LCH SA is also proposing 
additional conforming edits to align with the clarifications made in 
Section 5.3.1 (e.g., Section 5.3.2.3 ``Macroeconomic Scenario'' will be 
amended to align the assumptions made in Section 5.3.1) with the 
removal of the former assumptions that simulated a fixed effect on core 
and peripheral countries independently of a historical downgrade. LCH 
SA is making these changes to sovereign downgrade assumptions to 
address a Model Validation recommendation.
    In addition, LCH SA will clarify in Section 5.3.2.3 that the table 
presented is an example of the aggregation of exposure for a member 
group during the combined reverse stress test that includes multiple 
defaults and is presented for illustrative purposes only.
    Finally, LCH SA will also revise Appendix 6.2: ``Members behaviour 
analysis'', by removing the two charts and the global wording related 
to discussion around increase of margins and the specific case of 
Brexit. This reference is being removed as it is outdated and these 
elements are no longer part of the Framework methodology.
Appendix 6.7--Stress Scenarios List
    LCH SA will clarify that the scenario list disclosed is for 
informational purposes only and represents the list of scenarios at the 
time of drafting the current version of the Framework. The actual 
computation of liquidity metrics is dependent on the actual scenarios 
used to calibrate the default fund for LCH SA's different services and 
thus may differ. Moreover, only the scenario labels will be left in the 
Framework, as this is more applicable for scenario identification than 
scenario numbers.
Appendix 7--Operating Model and Main Data Source Used To Run Liquidity 
Metrics
    To address an independent Model Validation recommendation, a new 
section will be integrated to disclose a high-level functional workflow 
regarding the computation of liquidity metrics. The chart will be 
disclosed for informational purposes only, such that any revision will 
be made if LCH SA amends the methodology or the Framework.
New Procedure: LCR Metric Compliant With SEC Rules and Established 
Practices
    To complement the changes to the Framework, LCH SA is also 
proposing to create a new procedure for the purposes of describing the 
Liquidity Resources including in its LCR calculation for the purposes 
of complying with the SEC's cover 1 liquidity requirements. The 
procedure will detail the specific LCR methodology, the escalation 
process for any potential breaches in the specific cover 1 metric, the 
frequency of LCH SA's review of the LCR methodology and the controls in 
place regarding the calculation and ongoing review of the LCR metric 
compliant with the SEC's cover 1 liquidity requirements and established 
practices.
2. Statutory Basis
    LCH SA believes the Proposed Rule Change is consistent with the 
requirements of Section 17A of the Act \5\ and regulations thereunder 
applicable to it. Section 17A(b)(3)(F) of the Act requires, inter alia, 
that the rules of a clearing agency should be designed to ``promote the 
prompt and accurate clearance and settlement of securities transactions 
and, . . . to assure the safeguarding of securities and funds which are 
in the custody or control of the clearing agency or for which it is 
responsible[.]'' \6\

---------------------------------------------------------------------------

    The Framework is being amended primarily to enhance details about 
how LCH SA models for the liquidity needs arising from the daily 
settlement process in its RepoClear service related to the auto-
collateralization feature in its Framework and amend how LCH SA 
accounts for non-defaulting members' excess collateral in the 
calculation of the Standalone Operational Target as well as the LCR in 
its Framework. The proposed changes to the Framework regarding the 
auto-collateralization feature will allow LCH SA to utilize dynamic 
input data, including the most recent ECB haircuts and the actual auto-
collateralization limits set up in production at the time of 
monitoring. In addition, the Framework will be amended to provide a 
more targeted auto-collateralization limit, such that the allocated 
portion of the limit for each issuer, in the case where there is a 
distinct ECB category and haircut step and/or different operational 
readiness to transfer securities in bulk from T2S to the 3G Pool 
between different issuers assigned to the same DCA, will be defined 
based on the average daily settlement obligation per security over the 
last year for purposes of computing the liquidity impact. The proposed 
changes to the treatment of excess collateral in the Framework will 
allow LCH SA to modify the previous assumption that 100 percent of 
excess collateral is withdrawn immediately following a stress event in 
its Framework, to more closely align it with

[[Page 16910]]

current empirical clearing member behaviors and with the appropriate 
liquidity horizon period. Collectively, these change would strengthen 
LCH SA's ability to comprehensively manage its liquidity risks by 
ensuring it maintains sufficient liquid resources to facilitate the 
prompt and accurate clearance and settlement of securities transactions 
and assure the safeguarding of securities and funds in its control, 
consistent with Section 17A(b)(3)(F) of the Act.\7\

    LCH SA is proposing to provide additional specificity in its 
Framework to more accurately reflect how it models liquidity needs 
arising from the daily settlement process in its RepoClear service 
related to the auto-collateralization feature. Specifically, LCH SA is 
proposing to detail the operational steps by which LCH SA would utilize 
the auto-collateralization feature, as this information is not 
currently in the Framework. LCH SA is also proposing to amend the 
Framework to more accurately reflect real-time information, including 
the current ECB haircut schedule for sovereign debt securities and the 
limits determined through real-time monitoring for each debt type. In 
addition to the proposed changes related to the auto-collateralization 
feature, the proposed changes to the treatment of excess collateral 
would modify how LCH SA quantifies the liquidity drain related to 
Clearing Member withdrawal behaviors in a stress event. Under the 
Proposed Rule Change, the withdrawal of excess collateral would be 
modeled based on Clearing Member historical behavior and aligned with 
the seven-day liquidity horizon. That is, LCH SA will model for the 
partial withdrawal of excess collateral that is based on the second 
worst observed relative variation experienced over seven days, capped 
at the biggest historical reduction in excess collateral over the 
liquidity horizon. This process would utilize up to ten years of 
historical data and the result will be automatically integrated in the 
Operation Target on a daily basis and form the basis of a dedicated 
monitoring process. The Proposed Rule Change will also clarify that LCH 
SA will monitor how excess collateral is modelled in the intermediary 
days within the liquidity horizon and that any change to the 
assumptions in the Framework will require approval by the ERCo.
    LCH SA is also proposing to create a new procedure to describe its 
process for calculating the Liquidity Resources included in its LCR 
calculation to comply with the SEC's cover 1 liquidity requirements, 
detail the specific LCR cover 1 methodology, how it will escalate 
breaches in the daily review of the specific cover 1 metric, the 
frequency of LCH SA's review of the LCR methodology more broadly and 
the controls in place for how LCH SA will calculate and monitor the LCR 
metric to ensure ongoing compliance with the SEC's cover 1 liquidity 
requirements and established practices.
    Based on the foregoing, LCH SA believes the Proposed Rule Change 
will allow it to more effectively measure, monitor, and manage its 
liquidity risk, including by maintaining sufficient liquid resources in 
all relevant currencies to effect same-day and, where appropriate, 
intraday and multiday settlement of payment obligations consistent with 
Regulation 17Ad-22(e)(7)(i).\10\

    To address a regulatory examination observation and for purposes of 
simplifying how this information is presented in the Framework, LCH SA 
is making clarifying changes to how it calculates liquidity resources 
for purposes of meeting the minimum liquid resource requirements under 
Exchange Act rule 17Ad-22(e)(7).\16\ In addition to adding detail on 
the composition of liquid resources and to address an independent Model 
Validation observation and a regulatory examination finding, LCH SA is 
proposing to amend how it models for the substitution of liquid 
resources to non-liquid resources in its Framework. In doing so, LCH SA 
will quantify this substitution via a proxy by calibrating over the 
seven-day liquidity horizon using historical observations. To ensure 
this value remains accurate in the calculation of liquid resources, LCH 
SA will perform daily monitoring and calibrate the value should results 
reflect different assumptions and document this process in a procedure. 
In the case of any liquidity shortfalls, LCH SA will escalate to senior 
management to take any necessary actions.
---------------------------------------------------------------------------

    \16\ 17 CFR 240.17Ad-22(e)(7).
---------------------------------------------------------------------------

    In addition, LCH SA is also proposing to amend how it models excess 
collateral withdrawal by leveraging the historical behavior of its 
membership and using a lookback period that

[[Page 16911]]

includes times of stress. LCH SA s also proposing to include in the 
calculation of the Operation Target standalone a provision to model the 
potential switch of collateral from the full title transfer regime to 
the pledge regime calibrated on the historical behavior of its 
membership. This change will to be applied to the LCR, whereby this 
currently assumes more conservatively that all members that can pledge, 
will do so up to the maximum capacity possible.
    Finally, LCH SA proposes to update its Framework for independent 
reverse stress tests by revising the assumptions underlying its 
simulated Eurozone downgrade scenario, including the use of maximum 
downgrade notches from recognized rating agencies and recalibration of 
haircut categories per central bank rules. LCH SA is making these 
changes to the sovereign downgrade assumptions to address a Model 
Validation recommendation.
    LCH SA is also clarifying that it will only include non-cash 
resources in its liquidity resources under a cover 1 scenario after 
performing a comprehensive analysis and presenting to the Board not 
less than annually to ensure such prearranged funding arrangements are 
deemed highly reliable even in extreme but plausible market 
conditions.\17\ This clarification will align with LCH SA's Liquidity 
Plan and Liquidity Risk Management Policy and LCH SA therefore believes 
that the Proposed Rule Change is consistent with Regulation 17Ad-
22(e)(7)(ii) \18\ for purposes of holding sufficient liquid resources 
and Regulation 17Ad-22(e)(7)(vi)(A) \19\ for purposes of adequately 
modelling liquidity stress testing parameters and assumptions.

    As part of the process to assess the sufficiency of liquid 
resources held to meet the minimum liquid resource requirement set 
forth in Regulation 17Ad-22(e)(7)(i),\22\ LCH SA identified the need to 
enhance details about how it models for the liquidity needs arising 
from the daily settlement process in its RepoClear service related to 
the auto-collateralization feature in its Framework and amend how it 
accounts for non-defaulting members' excess collateral in the 
calculation of the operational target in its Framework. With respect to 
the auto-collateralization feature described in the Framework, LCH SA 
identified a need to:
---------------------------------------------------------------------------

    \22\ 17 CFR 240.17ad-22(e)(7)(i).
---------------------------------------------------------------------------

    (1) add detail with respect to the auto-collateralization feature, 
including the operational steps by which LCH SA would utilize the 
feature;
    (2) clarify that the maximum potential liquidity drain modelled is 
based on the operational effectiveness and readiness of the transfer of 
securities from T2S to the 3G Pool for each issuer, as demonstrated on 
an annual basis through LCH SA's War Games exercises,
    (3) specify how the actual limits for each debt type are determined 
and validated by internal stakeholders;
    (4) clarify that the most conservative ECB haircut of the relevant 
debt category and step currently in force will apply when determining 
the maximum liquidity drain; and
    (5) make other updates and conforming changes to align with 
proposed revisions in (1) through (4) above.
    LCH SA also identified a need to modify how LCH SA accounts for 
non-defaulting members' excess collateral in the calculation of the 
Standalone Operational Target as well as LCR in its Framework. 
Specifically, LCH SA identified the need to modify the Framework to 
quantify the withdrawal of excess collateral over a seven-day liquidity 
horizon based on the second worst observed relative variation 
experienced over seven days, capped at the biggest historical reduction 
in excess collateral, utilizing up to ten years of historical data, and 
implement daily back testing to ensure any changes in the partial 
withdrawal scenario are flagged to senior management, such that any new 
extreme would automatically be integrated in the Framework the 
following day. LCH SA is also proposing additional updates and 
confirming changes to the Framework for consistency. LCH SA believes 
the Proposed Rule Change is therefore appropriate for determining its 
liquidity needs and resources in light of current and evolving market 
conditions, consistent with Regulation 17Ad-22(e)(7)(vi)(B).\23\

B. Clearing Agency's Statement on Burden on Competition

    Section 17A(b)(3)(I) of the Act requires that the rules of a

appropriate in furtherance of the purposes of the Act.\24\ LCH SA does 
not believe the Proposed Rule Change would have any impact, or impose 
any burden, on competition. The Proposed Rule Change does not address 
any competitive issue or have any impact on the competition among 
central counterparties. LCH SA operates an open access model, and the 
Proposed Rule Change will have no effect on this model.
