BrokerTec Chicago U.S. Treasury CLOB - September 15

Effective Monday, September 15, 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 + CME EConnnect NY5) 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 and follow the same holiday schedule.

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

NewPersonally Identifiable Information (PII) Process Transition - Q4 2025

To be enabled for trading, all BrokerTec EU and UK participants are required to submit Personally Identifiable Information (PII) for manual traders and operators of algorithmic trading systems for the operator of the BrokerTec EU (CME Amsterdam B.V.) and UK (BrokerTec Europe Limited) trading venues to meet MiFID II / MiFIR transaction reporting and record keeping requirements. Participants are currently able to maintain PII via the NEX Upload Facility (NUF).

In Q4 2025, CME Group will replace the NUF process with the new PII process in the Request Center (ESS) within CME Customer Center.

The new PII process will offer participants improved visibility into each trader's PII status and allow for both individual PII maintenance and bulk uploads.

A new PII Manager role will be available in the Request Center and granted to current NUF users having an existing CME Group Login ID. User Administrators within each firm will manage the assignment of this new role to staff members, delegating PII maintenance responsibilities on behalf of their organization. It is required to create a CME Group Login with multifactor authentication to be granted the new PII Manager role.

Existing valid PII records will be transferred to the new PII process, where they will be accessible for the PII Manager to maintain using the new PII process.

Additional details will be announced in future notices. Please contact Global Account Management with questions or comments.

All personal information provided by customers is used, distributed, and maintained in accordance with CME Group’s Privacy Notice.

CME STP FIX on Google Cloud - Production Internet Connectivity - Now Available

On Sunday, May 11 (trade date Monday, May 12), CME Group enabled the Production internet connectivity options for CME STP FIX API as part of a phased migration of CME Straight Through Processing APIs to Google Cloud.

CME STP FIX service will operate in two regions, the Eastern and Central United States.

Clients have two different options for internet connectivity to CME STP FIX on Google Cloud.

CME STP FIX on Google Cloud - Production Internet Connectivity
Connectivity Option	CME STP FIX Hostname(s)	Usage
Managed	stpfix.api.cmegroup.com *[208.112.128.43]	Clients only need to connect to a single Host for all STP data that they are entitled to. CME Group will manage regional connectivity.
Regional	stpfix-a.api.cmegroup.com *[208.112.128.46] stpfix-b.api.cmegroup.com *[208.112.128.45]	Clients can connect to both regions in parallel, providing flexibility and redundancy. Clients can subscribe to the same or different STP trade data across regions based on their entitlements. Sequences of messages are not guaranteed to be the same across regions.

*Client systems are required to target the Hostname(s). IPs are provided for convenience of client side whitelisting.

CME STP FIX is accessible on port 443. Clients can use their existing API credentials.

CME STP FIX on Google Cloud is available in parallel to the current on-prem instance. Clients should ensure that they do not double-book trades if connecting in parallel to Google Cloud and on-prem instances.
