Dear Mr. Kirkpatrick:

Chicago Mercantile Exchange Inc. (“CME”) and The Board of Trade of the City of Chicago, Inc. (“CBOT”) 

(collectively, the “Exchanges”) certify to the Commodity Futures Trading Commission (“CFTC” or 

“Commission”) amendments amend the CME Globex electronic trading platform (“CME Globex”) hours for 

Basis Trade at Index Close (“BTIC”) transactions of the three (3) CME and CBOT commodity index futures 

contracts listed in Table 1. below effective Sunday, March 12, 2023 for trade date Monday, March 13, 2023.

Specifically, this amendment will harmonize the CME Globex BTIC trading hours with the respective 

underlying index close for all four (4) of the Exchanges’ commodity index futures contracts in Table 1.

below.

Additionally, the Exchanges will implement administrative changes to the four (4) CME and CBOT 

commodity index futures product chapters listed in Table 1. below (collectively, the “Rule Amendments”).

language. The Exchanges’ house specific trading hours on contract specification pages of each contract.
