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 the CME Group Client Systems Wiki.

CFTC's final rules became effective upon publication in the Federal Register on June 3, 2024. Subject to the conditions of the January 27, 2026, no-action letter, reporting firms must comply with these CFTC regulations by July 26, 2027.

A test environment for Large Trader Reporting is now available within the Firm Regulatory Portal (FRP UT). Users can access the testing portal at: https://frp.uat.cmegroup.com.

A brief video demonstration is available to highlight the new look and functionality of the FRP UT.

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