Position Reporting Under CFTC Part 17

On April 30, 2024, the Commodity Futures Trading Commission ("CFTC") approved final rules to amend its Large Trading Reporting Regulations for Futures and Options. The amendments were made to modernize CFTC's Large Trader Reporting process and align it with other reporting structures outlined in CFTC regulations.

Since October 2024, CME Group has offered methods to retrieve its instrument listing containing the Unique Instrument Code (UIC) and other instrument data elements in compliance with the amended rule.

Starting March 10, 2025, CME Group began accepting test files in the new Position Message FIXML format via SFTP. For details regarding submitting the new FIXML Position Message, file management, field validations, and example scenarios, please refer to the information in CME Group Client Systems Wiki.

The Market Regulation Department will be publishing further guidance regarding Large Trader Reporting in subsequent Special Executive Reports as solutions become available.

CFTC's final rules became effective upon publication in the Federal Register on June 3, 2024. Reporting Firms must comply with the CFTC's final rules regarding Large Trader Reporting Requirements two years after publication in the Federal Register.

NewCME Globex Treasury Futures Roll Messaging Efficiency Program Reminder - August 14

On Thursday, August 14 (trade date Friday, August 15), CME Group will activate the Messaging Efficiency Program (MEP) Treasury futures roll volume ratio in 5- and 10-Year Treasury Note futures in order to encourage responsible messaging practices during the Treasury futures roll period.

As a reminder, this additional volume ratio is enforced during each of the last 10 trade dates before First Notice Day during all Treasury futures roll periods. This ratio requires that for each day, all CME Globex Firm IDs that submit greater than 5 million per day of Order Entry Quantity in each of 5- or 10-Year Treasury futures product groups during a specific combined ETH and RTH trading session, during the last 10 trade dates before First Notice Day, maintain a ratio of 3,000 or less between Order Entry Quantity and executed volume. 

CME Globex Firm IDs who exceed the CME Globex Treasury futures roll MEP product group benchmark of 3,000:1 will face a potential daily surcharge of $10,000; a second surcharge in the same month, in the same product group, will be referred to CME Market Regulation. 

In addition to the Treasury futures roll scoring ratio in 5- and 10-Year Treasury Note futures, market participants will continue to be held to all other MEP volume ratios.

Please refer to the CME Globex Messaging Efficiency Program for additional information. 

Contact the CME Global Command Center in the U.S. at +1 800 438 8616, in Europe at +44 20 7623 4747, in Asia at +65 6532 5010, Japan at +81 3 6733 7559, or your Global Account Manager with any questions.
