Transitioning from Eurodollars to SOFR

To ensure a seamless transition from Eurodollars to SOFR, CME Group has worked closely with market participants to develop and implement both robust SOFR-based fallbacks for Eurodollars as well as efficient trading mechanisms for shifting positions to SOFR prior to June 2023.

Eurodollar positions become SOFR positions post-June 2023

On March 29, 2021, CME Group officially amended the Eurodollar futures and options rulebook to include SOFR-based fallbacks (view SER).

Upon the cessation of 3-month USD ICE LIBOR in June 2023:

  • All Eurodollar futures will be converted on a 1:1 basis into same month SR3 contracts with a price adjustment of 26.161bp. Conversion formula: SR3 futures assignment price = ED futures settlement price + 26.161 bps.
  • All Eurodollar options will be converted on a 1:1 basis into same month/expiry with 25 bp higher price strike. Prices will be adjusted to account for the difference in movement of 25 bp in strike vs 26.161 bp fallback spread.

Two ways to proactively move Eurodollar (ED) positions to SOFR (SR3) ahead of June 2023

  1. Reduced-tick SR3-ED spreads
    • Tradable in 0.1 bp increments around the ISDA fallback spread for 3M USD Libor
    • Each spread trade simultaneously executes a buy (sell) in SR3 vs. a sell (buy) in Eurodollars at a spread equal to 26.16 + the traded price
    • Available for same contract month ICS, Sep 2023 and beyond
    • Listed on CME Globex under the ticker SED and SEAA<Comdty> on Bloomberg
    • Executable as a block trade provided the sum of the legs meets the smaller of the threshold requirements for the underlying products
  1. Traditional SR3-ED inter-commodity spreads (ICS)
    • Quoted in 0.25 bp increments for the nearest term SOFR vs. ED, and 0.50 bp for all others listed in this spread
    • Listed as SOFR vs. ED on Globex (SR3Z2-EDZ2) and SFRED on Bloomberg
    • Executable as a block trade provided the sum of the legs meets the larger of the threshold requirements for the underlying products
    • One of the deepest pools of SOFR-based liquidity with ADV exceeding 250K contracts
