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.

CME Globex Connectivity Upgrades and Changes for Listed Derivative Markets - April

Starting in April, CME Group plans to replace End-of-Life network equipment that supports listed derivatives connectivity at CME Globex Hubs. Customers will be notified in advance if they are impacted by an equipment upgrade.

CME Globex market data for listed derivatives now regularly exceeds 1Gbps, increasing the risk of packet loss, performance concerns, and quality of service degradations on 1Gbps connections.

Impact on 1Gbps Listed Derivatives Connections

• Multicast Market Data: Effective in March 2026, 1Gbps services will no longer support MDP 3 multicast market data.
• Existing 1Gbps Customers with Market Data: Customers with 1Gbps service currently listening to multicast market data are encouraged to upgrade connections to 10Gbps as soon as possible.
• Existing 1Gbps Customers without Market Data: Unicast services such as iLink, Drop Copy, STP, MQ and others will continue to be supported on 1Gbps connections. Customers with 1Gbps connectivity who are not receiving Market Data will have their service migrated to the new equipment.
• New 1Gbps Connections: Effective immediately, new connections for 1Gbps service will not support access to listed derivatives multicast market data.

Copper Handoffs

• When the CME Globex Connectivity upgrades are rolled out in 2026, CME Group will no longer support copper handoffs.

Additional details about the CME Globex Connectivity upgrades will be announced in future CME Globex Notices.

Please contact your Global Account Manager for additional information.
