I. Introduction

    On December 2, 2022, National Securities Clearing Corporation 
(``NSCC'') filed with the Securities and Exchange Commission 
(``Commission'') proposed rule change SR-NSCC-2022-015 (the ``Proposed

II. Summary of the Proposed Rule Change

    A key tool that NSCC uses to manage its respective credit exposures 
to its members is the daily collection of margin from each member, 
which is referred to as each member's Required Fund Deposit.\8\ The 
aggregated amount

[[Page 17899]]

of all members' margin constitutes the Clearing Fund, which NSCC would 
access should a defaulted member's own margin be insufficient to 
satisfy losses to NSCC caused by the liquidation of that member's 
portfolio.
---------------------------------------------------------------------------

    \8\ The description of the Proposed Rule Change is based on the 
statements prepared by NSCC in the Notice. See Notice, supra note 3. 
Capitalized terms used herein and not otherwise defined herein are 
defined in the Rules, available at https://www.dtcc.com/-/media/Files/Downloads/legal/rules/nscc_rules.pdf.
---------------------------------------------------------------------------

    Each member's margin consists of a number of applicable components, 
each of which is calculated to address specific risks faced by NSCC.\9\ 
Generally, the largest portion of a member's margin is the volatility 
component, often referred to as the VaR Charge, which is designed to 
reflect the amount of money that could be lost on a portfolio over a 
given period within a 99th percentile level of confidence. Under NSCC's 
current rules, one of the potential methods of calculating the VaR 
Charge relies on a measure of gap risk.\10\ It does not accrue for all 
portfolios, but instead only serves as the VaR Charge if it is the 
largest of three potential calculations.\11\ The gap risk charge was 
designed to address the risk presented by a portfolio that is more 
susceptible to the effects of gap risk events, i.e., those portfolios 
holding positions that represent more than a certain percent of the 
entire portfolio's value, such that the event could impact the entire 
portfolio's value.\12\
---------------------------------------------------------------------------

    \9\ See Procedure XV of the Rules, supra note 8.
    \10\ Gap risk events have been generally understood as 
idiosyncratic issuer events (for example, earning reports, 
management changes, merger announcements, insolvency, or other 
unexpected, issuer-specific events) that cause a rapid shift in 
price volatility levels.
    \11\ Specifically, the VaR Charge is the greatest of (1) the 
larger of two separate calculations based on different underlying 
estimates that utilize a parametric VaR model, which addresses the 
market risk of a member's portfolio (referred to as the core 
parametric estimation), (2) the gap risk calculation, and (3) a 
portfolio margin floor calculation based on the market values of the 
long and short positions in the portfolio, which addresses risks 
that might not be adequately addressed with the other volatility 
component calculations.
    \12\ See Section I(A)(1)(a)(i)II and I(A)(2)(a)(i)II of 
Procedure XV of the Rules, supra note 8. See also Exchange Act 
Release Nos. 82780 (Feb. 26, 2018), 83 FR 9035 (Mar. 2, 2018) (SR-
NSCC-2017-808); 82781 (Feb. 26, 2018), 83 FR 9042 (Mar. 2, 2018) 
(SR-NSCC-2017-020) (``Initial Filing'').
---------------------------------------------------------------------------

    To calculate the gap risk charge, NSCC multiplies the gross market 
value of the largest non-index net unsettled position in the portfolio 
by a gap risk haircut, which can be no less than 10 percent (``gap risk 
haircut'').\13\ Currently, NSCC determines the gap risk haircut 
empirically as no less than the larger of the 1st and 99th percentiles 
of three-day returns of a set of CUSIPs that are subject to the VaR 
Charge pursuant to the Rules, giving equal rank to each to determine 
which has the highest movement over that three-day period. NSCC uses a 
look-back period of not less than ten years plus a one-year stress 
period, and if the one-year stress period overlaps with the look-back 
period, only the non-overlapping period would be combined with the 
look-back period. The resulting haircut is then rounded up to the 
nearest whole percentage and applied to the largest non-index net 
unsettled position to determine the gap risk charge.
---------------------------------------------------------------------------

    \13\ See Section I(A)(1)(a)(i)II and I(A)(2)(a)(i)II of 
Procedure XV, supra note 8.
---------------------------------------------------------------------------

    As described in the Notice, NSCC proposes to modify Procedure XV 
(Clearing Fund Formula and Other Matters) of NSCC's Rules & Procedures 
(``Rules'') to make the following changes to the gap risk charge: (1) 
make the gap risk charge an additive component of the member's total 
VaR Charge when it is applicable, rather than being applied as the 
applicable VaR Charge only when it is the largest of three separate 
calculations, (2) adjusting the gap risk charge to be based on the two 
largest positions in a portfolio, rather than based on the single 
largest position, (3) changing the floor of the gap risk haircut from 
10 percent to 5 percent for the largest position, adding a floor of the 
gap risk haircut of 2.5 percent for the second largest position, and 
providing that gap risk haircuts would be determined based on 
backtesting and impact analysis, and (4) amending which ETF positions 
are excluded from the gap risk charge to more precisely include ETFs 
that are more prone to gap risk, i.e., are non-diversified.

III. Proceedings To Determine Whether To Approve or Disapprove the 
Proposed Rule Change and Grounds for Disapproval Under Consideration

    The Commission is instituting proceedings pursuant to Section 
19(b)(2)(B) of the Act \14\ to determine whether the Proposed Rule 
Change should be approved or disapproved. Institution of proceedings is 
appropriate at this time in view of the legal and policy issues raised 
by the Proposed Rule Change. Institution of proceedings does not 
indicate that the Commission has reached any conclusions with respect 
to any of the issues involved. Rather, the Commission seeks and 
encourages interested persons to comment on the Proposed Rule Change, 
providing the Commission with arguments to support the Commission's 
analysis as to whether to approve or disapprove the Proposed Rule 
Change.

participants and those arising from its payment, clearing, and 
settlement processes, including by maintaining sufficient financial 
resources to cover its credit exposure to each participant fully with a 
high degree of confidence.
