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.
