SECURITIES AND EXCHANGE COMMISSION

[Release No. 34-80849; File No. SR-LCH SA-2017-004]


Self-Regulatory Organizations; LCH SA; Order Approving Proposed 
Rule Change Relating to LCH SA's CDS Margin and Extreme Credit Spread 
Curves

June 2, 2017.

I. Introduction

    On April 4, 2017, Banque Central de Compensation, which conducts 
business under the name LCH SA (``LCH SA''), filed with the Securities 
and Exchange Commission (``Commission''), pursuant to Section 19(b)(1) 
of the Securities Exchange Act of 1934 (``Act'') \1\ and Rule 19b-4 
thereunder,\2\ a proposed rule change (SR-LCH SA-004) to amend its CDS 
margin framework to replace an algorithm-based approach to pricing 
credit default swaps (``CDS'') in the event extreme spread curves cause 
the International Swaps and Derivatives Association Standard Model for 
pricing credit default swaps (``ISDA Pricer'') to fail with an 
approximation-based method.\3\ The proposed rule change was published 
for comment in the Federal Register on April 19, 2017.\4\ The 
Commission received no comment letters regarding the proposed change. 
For the reasons discussed below, the Commission is approving the 
proposed rule change.

II. Description of the Proposed Rule Change

    LCH SA has proposed to amend its CDS margin framework. The proposed 
change would alter the approach used by LCH SA when the ISDA Pricer, 
used in pricing CDS, fails as a result of extreme spread curves. Under 
its current CDS margin framework, LCH SA uses the ISDA Pricer to 
calibrate credit spread curves as part of its spread margin component. 
According to LCH SA, the ISDA Pricer cannot be used to calibrate credit 
spread curves where ``extreme'' credit spread curves exist.\5\ In the 
event that the ISDA Pricer fails due to the existence of extreme credit 
spread curves, LCH SA has established a dichotomy-based algorithm that 
it uses to adjust the inputs and calibrate the spread curves 
iteratively until it identifies the tenor causing the calibration to 
fail, and the closest spread to that tenor that will allow the curve to 
appropriately calibrate.\6\

    LCH SA represented that this dichotomy-based algorithm can consume 
significant amounts of time to process because of the number of 
repetitions that may be necessary for the process to produce the 
appropriate results, which could result in delays in calculating margin 
requirements.\7\ To ameliorate the potential for these delays, LCH SA 
has proposed to amend its approach by replacing the dichotomy-based 
algorithm described above with an approximation-based approach under 
which LCH SA would, in the event that the ISDA Pricer fails, construct 
a piecewise hazard rate curve and a piecewise constant interest rate 
curve, and then apply average hazard and interest rates for the 
relevant period to price the relevant CDS.\8\

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

    LCH SA represents that it has performed quantitative analysis, 
which indicates that the revised approach to calculating margin 
requirements in the event that the ISDA Pricer fails is a reliable 
pricing tool.\9\ Therefore, this revised approach is not likely to 
result in significant changes to CDS prices and margin requirements 
calculated using LCH SA's current approach.

III. Discussion and Commission Findings

    Section 19(b)(2)(C) of the Act directs the Commission to approve a 
propose rule change of a self-regulatory organization if it finds that 
such proposed rule change is consistent with the requirements of the 
Act and the rules and regulations thereunder applicable to such 
organization.\10\ Section 17A(b)(3)(F) of the Act requires, among other 
things, that the rules of a registered 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.\11\ Rule 17Ad-22(e)(17) requires, in 
relevant part, that each covered clearing agency establish, implement, 
maintain, and enforce written policies and procedures reasonably 
designed to manage a covered clearing agency's operational risk by 
identifying the plausible sources

[[Page 26722]]

of operational risk, both internal and external, and mitigating their 
impact through the use of appropriate systems, policies, procedures and 
controls, as well as to ensure that systems have a high degree of 
security, resiliency, operational reliability, and adequate, scalable 
capacity.\12\ Rule 17Ad-22(b)(1) requires, in relevant part, a 
registered clearing agency that performs central counterparty services 
to establish, implement, maintain and enforce written policies and 
procedures that are reasonably designed to measure the registered 
clearing agency's credit exposures to its participants at least once 
daily and limit its exposures to potential losses from participant 
defaults under normal market conditions.\13\ Rule 17Ad-22(b)(2) 
requires, in relevant part, a registered clearing agency that performs 
central counterparty services to establish, implement, maintain and 
enforce written policies and procedures that are reasonably designed to 
use margin requirements to limit its credit exposures to participants 
under normal market conditions and use risk-based models and parameters 
to set margin requirements.\14\ Rule 17Ad-22(e)(6) requires, in 
relevant part, a covered clearing agency that provides central 
counterparty services to cover its credit exposures to its participants 
by establishing a risk-based margin system that, at a minimum, 
considers and produces margin levels commensurate with the risks and 
particular attributes of each relevant product, portfolio and market, 
and marks participant positions to market and collects margin, 
including variation margin or equivalent charges if relevant, at least 
daily.\15\

    \11\ 15 U.S.C. 78q-1(b)(3)(F).
    \12\ 17 CFR 240.17Ad-22(e)(17).
    \13\ 17 CFR 240.17Ad-22(b)(1).
    \14\ 17 CFR 240.17Ad-22(b)(2).
    \15\ 17 CFR 240.17Ad-22(e)(6)(i) and (ii).
---------------------------------------------------------------------------

    The Commission finds that the proposed rule change is consistent 
with Section 17A(b)(3)(F) of the Act and the relevant provisions of 
Rule 17Ad-22 thereunder. The Commission believes that the proposed rule 
change will reduce the risk that the process for determining spread 
margin requirements will require excessive time to process in the event 
that extreme spread curves cause the ISDA Pricer to fail; the proposed 
rule change thereby will improve LCH SA's operational ability to 
calculate its margin requirements promptly without sacrificing 
accuracy. Because it will facilitate the calculation of margin 
requirements in a timely fashion, the proposed rule change is 
consistent with the prompt and accurate clearance and settlement 
requirement of Section 17A(b)(3)(F) of the Act and with operational 
risk requirements of Rule 17Ad-22(e)(17).
    The Commission also believes that the proposed rule change provides 
for an approach that takes into consideration relevant risks (including 
hazard rates and interest rates) in order to provide for appropriate 
method for calculating CDS prices, and consequently the measurement of 
LCH SA's credit exposures and margin requirements, in the event that 
the ISDA Pricer fails. As a result, the proposed rule change is 
consistent with requirements of Rules 17Ad-22(b)(1) and (2), and Rule 
17Ad-22(e)(6).

IV. Conclusion

    It is therefore ordered pursuant to Section 19(b)(2) of the Act 
that the proposed rule change (SR-LCH SA-2017-004) be, and hereby is, 
approved.\16\

considered the proposal's impact on efficiency, competition, and 
capital formation. 15 U.S.C. 78c(f).
