Termination of Trading, Conversion and Delisting of Standard-Size S&P 500 Index Contracts

The following amendments of the Chicago Mercantile Exchange Inc. (“CME”) contracts are detailed below and in SER-8828 and CME Submission No. 21-344.

The CME rule amendments to facilitate the conversion of unexpired open positions in Standard and Poor’s 500 Stock Price Index Futures (“Standard-Size Futures”) and Options on Standard and Poor’s 500 Stock Price Index Futures (“Standard-Size Options”) (collectively, “Standard-Size Contracts”) will be effective, pending all relevant CFTC regulatory review periods, at the close of business on Friday, September 17, 2021, into notionally equivalent positions in E-mini Standard and Poor’s 500 Stock Price Index Futures (“E-mini Futures”) or Options on E-mini Standard and Poor’s 500 Stock Price Index Futures (“E-mini Options”) (collectively, “E-mini Contracts”) at a fixed 1:5 ratio. Following completion of the conversion process on September 19, 2021, there will be zero (0) open interest in the Standard-Size Contracts and they will be immediately delisted.

Effective immediately upon completion of the conversion process at the close of business on Friday, September 17, 2021 (pending all relevant CFTC regulatory review periods), CME will adjust the CME Position Limit, Position Accountability and Reportable Level Table. The notional size of position limits will remain the same after the conversion, but the table will be revised to reflect E-mini Contract position size rather than Standard-Size Contract position size.
