Self-Regulatory Organizations; Fixed Income Clearing Corporation; Order Instituting Proceedings To Determine Whether To Approve or Disapprove a Proposed Rule Change To Modify the Calculation of the MBSD VaR Floor To Incorporate a Minimum Margin Amount

I. Introduction

On November 20, 2020, Fixed Income Clearing Corporation (“FICC”) filed with the Securities and Exchange Commission (“Commission”), pursuant to Section 19(b)(1) of the Securities Exchange Act of 1934 (“Act”) and Rule 19b-4 thereunder, proposed rule change SR-FICC-2020-017 to introduce a new “Minimum Margin Amount” to complement the existing VaR Floor calculation. The proposed rule change was published for comment in the Federal Register on December 10, 2020. The Commission has received comment letters on the proposed rule change. On December 23, 2020, pursuant to Section 19(b)(2) of the Act, the Commission designated a longer period within which to approve, disapprove, or institute proceedings to determine whether to approve or disapprove the proposed rule change and the Commission designated a longer period for comment on the proposed rule change. This order institutes proceedings, pursuant to Section 19(b)(2)(B) of the Act, to determine whether to approve or disapprove the proposed rule change.

II. Summary of the Proposed Rule Change

A. Background

FICC, through its Mortgage-Backed Securities Division (“MBSD”), serves as a central counterparty (“CCP”) and provider of clearance and settlement services for the non-private label mortgage-backed securities markets. A key tool that FICC uses to manage its respective credit exposures to its members is collecting margin from each member. The aggregated amounts of all members' margin constitutes the Clearing Fund, which FICC would access should a defaulted member's own margin be insufficient to satisfy losses to the CCP caused by the liquidation of that member's portfolio.

Each member's margin consists of a number of applicable components, including a value-at-risk (“VaR”) Charge designed to capture the potential market price risk associated with the securities in a member's portfolio. The VaR Charge is typically the largest of the margin components.

To determine the VaR Charge, FICC generally uses a risk-based calculation designed to quantify the risks related to the volatility of market prices associated with the securities in a member's portfolio. However, FICC also uses a haircut-based calculation to determine a VaR Floor, which replaces the risk-based calculation to become a member's VaR Charge in the event that the VaR Floor is greater than the amount determined by the risk-based calculation, operating as a minimum VaR Charge. FICC uses the VaR Floor to mitigate the risk that the risk-based calculation does not result in margin amounts that accurately reflect FICC's applicable credit exposure, which may occur in certain member portfolios containing long and short positions in different asset classes that share a high degree of historical price correlation.

B. Minimum Margin Amount

FICC is proposing to introduce a new calculation called the “Minimum Margin Amount” to complement the existing VaR Floor calculation. Under the proposal, FICC would revise the existing definition of the VaR Floor to be the greater of (1) the current VaR Floor calculation, and (2) the Minimum Margin Amount. The Minimum Margin Amount would enhance FICC's margin collection during periods of market volatility, particularly when TBA price changes significantly exceed those implied by the VaR model risk factors, such as rates and option-adjusted spread. FICC observed this situation occur during March and April 2020, with the result that margin amounts collected were not sufficient to mitigate FICC's credit exposure to its members' portfolios. The Minimum Margin Amount would be calculated based on historical price movements of the securities in the member's portfolio. Specifically, FICC would use a dynamic haircut method based on observed TBA price moves that would provide a more reliable estimate for the portfolios' risk level when current market conditions deviate from historical observations.

The Minimum Margin Amount would be a minimum volatility calculation for specified net unsettled positions, calculated using the historical market price changes of such benchmark TBA securities determined by FICC. The Minimum Margin Amount would cover such range of historical market price moves and parameters using a look-back period of no less than one year and no more than three years.

C. Summary of the Effect of the Changes Proposed in the Proposed Rule Change

FICC performed an impact study on members' portfolios for the period beginning February 3, 2020 through June 30, 2020. On average, at the member level, FICC found that the Minimum Margin Amount would have increased the VaR Charge by $27 million during the period of the impact study. The largest percent increase in VaR Charge for any member would have been 146%, or $22 million. The largest dollar increase for any member would have been $333 million, or 37% increase in the VaR Charge. The top 10 members based on the size of their VaR Charges would have contributed 69.3% of the aggregate VaR Charges had the Minimum Margin Amount been in place. The same members would have contributed to 54% of the increase resulting from the Minimum Margin Amount.

Backtesting studies indicate that average daily Backtesting Charges would have decreased by approximately $450 million or 53% during the impact study period and the overall margin backtesting coverage (based on 12 month trailing backtesting) would have improved from approximately 97.3% to 98.5% through June 30, 2020 if the Minimum Margin Amount calculation had been in place.

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 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, and provide the Commission with arguments to support the Commission's analysis as to whether to approve or disapprove the proposed rule change.

Pursuant to Section 19(b)(2)(B) of the Act, the Commission is providing notice of the grounds for disapproval under consideration. The Commission is instituting proceedings to allow for additional analysis of, and input from commenters with respect to, the proposed rule change's consistency with Section 17A of the Act, and the rules thereunder, including the following provisions:

• Section 17A(b)(3)(F) of the Act, which requires, among other things, that the rules of a clearing agency must be designed 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 and to protect investors and the public interest;

• Section 17A(b)(3)(I) of the Act, which requires that the rules of a clearing agency do not impose any burden on competition not necessary or appropriate in furtherance of the purposes of the Act;

• Rule 17Ad-22(e)(4)(i) under the Act, which requires a covered clearing agency establish, implement, maintain and enforce written policies and procedures reasonably designed to effectively identify, measure, monitor, and manage its credit exposures to 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;

• Rule 17Ad-22(e)(6)(i) and (v) under the Act, which require a covered clearing agency to establish, implement, maintain and enforce written policies and procedures reasonably designed to cover its credit exposures to its participants by establishing a risk-based margin system that, at a minimum (1) considers, and produces margin levels commensurate with, the risks and particular attributes of each relevant product, portfolio, and market, and (2) uses an appropriate method for measuring credit exposure that accounts for relevant product risk factors and portfolio effects across products; and
• Rule 17Ad-22(e)(23)(ii) under the Act, which requires a covered clearing agency establish, implement, maintain and enforce written policies and procedures reasonably designed to provide sufficient information to enable participants to identify and evaluate the risks, fees, and other material costs they incur by participating in the covered clearing agency.
