SOFR Discounting and Price Alignment Transition - Proposal for Cleared Swaps

After extensive consultation with our client base and the ARRC Paced Transition Working Group, CME Group has developed a high-level proposal for transitioning price alignment and discounting for USD OTC cleared swaps from the daily effective federal funds rate (EFFR) to SOFR. Our goal in publishing this proposal is to facilitate discussion on how this transition would be implemented.  CME Group looks forward to working with the industry to continue building consensus on the best path forward for achieving single-day discounting conversion for existing swaps.

Scope:  Cleared US dollar interest rate swap products at the respective clearinghouse.  At CME this includes:

Fixed/Float IRS

Overnight Index Swaps

Forward Rate Agreements

Zero Coupon Swaps

Basis Swaps


Timing:  Given the goal of accelerating the timelines outlined in the ARRC Paced Transition Plan, and in consideration of other events scheduled for H2-2020 (e.g., Phase V implementation of Uncleared Margin Rules, U.S. elections), we would propose targeting a transition date of July 17, 2020.

Process: After close of business on July 17, 2020, CME would conduct a standard end-of-day valuation cycle, moving variation margin and cash payments as calculated with EFFR discounting and price alignment.  Upon completion of this initial cycle, CME would then conduct a special cycle in which positions will be valued with SOFR discounting.

Cash Compensation:  To neutralize the value transfer attributed to the change in the discounting rate, CME would make a cash adjustment that is equal and opposite to the change in each cleared swap’s net present value (NPV) as part of the special cycle.  

Cash Compensation Example

Net Present Value  
Trade Standard Cycle EFFR Discounted Special Cycle SOFR Discounted NPV Difference Offsetting Adjustment Net Cash Flow
Position 1 $442,528 $456,214 $13,686 ($13,686) $0
Position 2 ($208,621) ($212,879) ($4,258) $4,258 $0
Position 3 $26,730 $27,000 $270 ($270) $0
Position 4 ($726,075) ($756,328) ($30,253) $30,253 $0
Position 5 $528,961 $545,321 $16,360 ($16,360) $0
Total $63,523 $59,328 ($4,195) $4,195 $0

Discounting Risk Exchange: By changing the discounting curve, CME would effectively move the discounting risk of all participants from EFFR to SOFR at closing curve levels on July 17, 2020, as illustrated by the hypothetical examples below.

17-Jul-20 Starting Risk (DV01) Conversion Risk Change Post Conversion Risk
Firm 1 $218,076 $0 ($218,076) $218,076 $0 $218,076
Firm 2 $240,663 $0 ($240,663) $240,663 $0 $240,663
Firm 3 ($86,923) $0 $86,923 ($86,923) $0 ($86,923)
Firm 4 $110,181 $0 ($110,181) $110,181 $0 $110,181
Firm 5 ($481,997) $0 $481,997 ($481,997) $0 ($481,997)

To mitigate hedging costs associated with this transition and sensitivity to closing curve marks on July 17, 2020, CME would book a series of EFFR/SOFR basis swaps to participants’ accounts.  These swaps would restore participants back to their original risk profiles and be booked at the July 17, 2020 closing curve levels ($0 NPV).  The examples below illustrate the proposed process.  (Please note that risk exposures would be bucketed and exchanged at key benchmark tenors during the actual transition.)  

17-Jul-20 Pre-Risk Exchange Risk Basis Swap Risk Post Risk Exchange
Firm 1 $0 $218,076 $218,076 ($218,076) $218,076 $0
Firm 2 $0 $240,663 $240,663 ($240,663) $240,663 $0
Firm 3 $0 ($86,923) ($86,923) $86,923 ($86,923) $0
Firm 4 $0 $110,181 $110,181 ($110,181) $110,181 $0
Firm 5 $0 ($481,997) ($481,997) $481,997 ($481,997) $0

To facilitate smooth operational processing of this risk exchange, participants would be able to choose to have these swaps booked as either:

  • Float-versus-float basis swaps, or
  • Pairs of fixed-versus-float swaps with equal and opposite fixed cash flows

Effective July 20, 2020, and thereafter, CME would utilize SOFR discounting and price alignment on all US dollar interest rate swap trades.

CME Group fully supports efforts to promote liquidity in the SOFR benchmark and looks forward to facilitating wider adoption of SOFR in continued partnership with the industry.
