Re: CFTC Regulation 40.6(d) Notification. Chicago Mercantile Exchange Inc. (“CME” or 

“Exchange”) Weekly Notification of Amendments Related to Product Terms and 

Conditions.

CME Submission No. 23-417

Dear Mr. Kirkpatrick:

Pursuant to Commodity Futures Trading Commission (“CFTC” or “Commission”) Regulation 40.6(d), the 

Exchange submits this weekly notification of the following amendments related to product terms and 

conditions effective during the week of September 18, 2023.

On September 22, 2023, the Exchange implemented administrative amendments to the CME Rule 589. 

Special Price Fluctuation Limits and Daily Price Limits table (the “Table”) to include certain treasury weekly 

contracts as noted in Exhibit A (the “Contracts”). The Contracts were inadvertently omitted from the Table. 

However, Rule 589. has always operationally applied to the Contracts. Exhibit A provides amendments to 

the Table in blackline format.

Should you have any questions concerning the above, please contact the undersigned at (212) 299-2200 

or via e-mail at CMEGSubmissionInquiry@cmegroup.com.

Sincerely, 

/s/ Christopher Bowen

Managing Director and Chief Regulatory Counsel
