Critical System Information

BrokerTec U.S. Repo Managed Order Enrichment - Q2 2025

Effective Q2 2025, BrokerTec on CME Globex will introduce the new Top of Stack (TOS) priority feature for U.S. Repo instruments. TOS prioritizes the passive managed order of the TOS owner based on the pre-defined TOS requirements. 

More details on the TOS functionality are now available in the client impact assessment. 

With this launch, BrokerTec U.S. Repo clients can receive the Unsolicited Modify message in a scenario when the passive managed order (i.e. tag 6881-ManagedOrder=1) is reprioritized with quantity adjustment. See Unsolicited Modify Acknowledgment Messages for more information on this type of order modification. Currently, iLink tag 6881 is for internal use only.  

The new TOS for products subject to this change are currently available for customer testing in New Release.

UpdateBrokerTec Chicago U.S. Treasury CLOB - Q3 2025

† Denotes update to the article

Effective Q3 2025, CME Group is launching BrokerTec Chicago, a secondary U.S. Treasury (UST) Actives Central Limit Order Book (CLOB) on CME Globex, operated by BrokerTec Americas LLC and located in the CME futures and options data center in Aurora, IL. BrokerTec Chicago is designed to enable clients to efficiently manage their cash vs. futures trading with greater precision. The products are tailored for cash vs. futures trading with tighter price and contract notional values aligning with futures, which differentiates this new venue from the existing BrokerTec U.S. Treasury Actives Market CLOB.

The new products offered with BrokerTec Chicago replicate the existing BrokerTec UST active instruments with similar contract size. The notional values for 1 lot size equivalents are $100k (5yr, 7yr, 10yr, 20yr, and 30yr) and $200k (2yr and 3yr) and the products have a price precision of 9 decimals (1/16 of a 32nd).

Clients with listed derivatives connectivity can access BrokerTec Chicago with existing cross-connects. Clients using BrokerTec Secaucus († GLink + EConnnect) connectivity can access BrokerTec Chicago, but require additional CME network and client-side configurations.

Trading hours for BrokerTec Chicago instruments are identical to the existing BrokerTec UST Actives instruments.

More information on the BrokerTec Chicago U.S. Treasury CLOB is available in the client impact assessment.

CME GC Allocator API Migration to Google Cloud - Now Available

The CME GC Allocator API is now available in Google Cloud.

Details on CME GC Allocator API hosted on Google Cloud are below: 

GC Allocator API Endpoints
Environment	Current URL / IP	Google Cloud URL / IP
Production (via Internet)	https://api.gcallocator.cmegroup.com/ 205.209.196.176	https://posttrade.api.cmegroup.com/gca/v2 208.112.128.6
New Release (via Internet)	https://api.gcallocator-nr.cmegroup.com/ 164.74.123.38	https://posttrade.api.uat.cmegroup.com/gca/v2 208.112.192.6

The current URLs for CME GC Allocator API endpoints will be decommissioned in Q2 2025:

• New Release will be decommissioned on April 12
• Production will be decommissioned in June 2025

Customers are strongly encouraged to access the CME GC Allocator API over the Internet to leverage Google Cloud automated failover capabilities. Customers requiring access to the CME GC Allocator API over dedicated connectivity can find the required information in the Client Systems Wiki.

GET requests with "content-type" header set to "application/json" will be rejected with a 400 return code when connecting to theCME GC Allocator API - hosted by Google Cloud. To avoid this issue, please remove the "content-type" header from all GET requests targeting the CME GC Allocator API endpoints. 

Due to a restriction within Google Apigee, query parameters with the same name cannot be repeated in a GET request. This restriction is in place to ensure predictable behavior and avoid potential ambiguity in how the API processes the request.
For example, the following previously supported request:

/trades/search?collateralStatus=NONE?collateralStatus=PARTIAL

must now be submitted as two separate requests:

/trades/search?collateralStatus=NONE

/trades/search?collateralStatus=PARTIAL

Clients can continue to use their existing OAuth API IDs to access the CME GC Allocator API in Google Cloud.

Redesigned Request Center Within CME Customer Center - Coming Soon

In the coming months, the Request Center within the CME Customer Center self-service functionality will feature a simplified, redesigned interface and streamlined navigation. For a clear and consistent experience across CME Group services, the Request Center will include updated terminology and instances of spelled out acronyms.

There will be no major functional updates to the user interface at this time and access will remain based on individual CME Group Login entitlements.

Currently, "Registered Entity" or "Administration Group" identifies a customer firm within the Request Center and the redesign will feature "Administration Group" for consistency.

Acronyms currently in the user interface will be spelled out, such as "Globex Firm ID," "Futures and Options" and "Order Entry" naming will identify the "iLink Sessions."

Additional details will be provided in future notices.
