Effective on September 10, 2025, and pending all relevant CFTC regulatory review periods, Chicago Mercantile Exchange Inc. (“CME”), in its capacities as a derivatives clearing organization (“DCO” or “Clearing House”) will amend CME Rules 8F002.-8F004. and 8F010. (collectively, the “Rule Amendments”) in connection with plans to list CME Event Contract Swaps.

CME Chapter 8-F (“Over-the-Counter Derivative Clearing”) establishes rules for approving firms as OTC Clearing Members to clear OTC Derivatives (e.g., commodity swaps and Event Contract Swaps) in the Base Guaranty Fund, as those terms are defined in Chapter 8-F.

The Rule Amendments may be found in Exhibit 1 below with additions underscored and deletions struck through. Please also see SER-9600 also dated August 25, 2025 for additional rule amendments regarding plans to list CME Event Contract Swaps.

If you are not already an OTC Clearing Member and are interested in being approved as one, including with regards to the clearing of event contract swaps, or have any questions, please contact Clearing Risk Management: clearingmembership@cmegroup.com or +1(312)-648-3888
