Critical Updates

New7 Day iLink CGW Sessions - May 3

Effective Sunday, May 3 (trade date Monday, May 4), new 7 day (7D) sessions will be required for all iLink and Drop Copy Convenience Gateway (CGW) users to participate in CME Globex 24/7 weekend trading. These 7D CGW sessions can be used to trade all 5 day and 7 day products moving forward.

iLink CGW users must create new 7D CGW sessions, which are now available in the Request Center (ESS), but will not be available for trading until Sunday, May 3.

Drop Copy CGW users must update their configuration to include a new dedicated target session, which will be auto-created by the Drop Copy service to support 7D CGW sessions.

Existing 5 day (5D) CGW sessions may be used to trade 7 day products from Sunday at 5:00 p.m. Central Time (CT) through Friday at 4:00 p.m. CT, but will be restricted from extended weekend trading hours.

To facilitate the transition, CME Group will waive Port Activation Charges (PAC) for all 7D sessions through July 2026. Monthly Inactivity Charges (MIC) remain in effect; a minimum of 100 traded contracts per month is required to avoid the $100 service charge.

Please Note: 7D sessions will not be available for weekend testing (mock trading sessions). Firms interested in weekend testing should retain a small number of 5D CGW sessions for this purpose. CME Group will waive the MIC for up to five 5D CGW sessions, maintained specifically for testing, per CME Globex Firm ID (GFID).

iLink and Drop Copy Market Segment Gateway (MSGW) sessions are unaffected and can access all 24/7 products, provided the associated GFID is enabled by the responsible FCM.

Please contact Global Account Management with any questions.

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.

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.

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. Subject to the conditions of the January 27, 2026, no-action letter, reporting firms must comply with these CFTC regulations by July 26, 2027.

Events and Announcements

CME Globex Connectivity Upgrades and Changes for Listed Derivative Markets - June 27

In response to client feedback and to provide firms with additional time to prepare, CME Group extended the deadline for the previously announced network equipment upgrades.

Starting Saturday, June 27, 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 June 27, 1Gbps services will no longer support MDP 3.0 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: New connections for 1Gbps service do 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.
