CME: Price Precision Extension and Globex MDP3 SBE Schema Update

August 12 – January 13

Per CME Globex Notices (some information omitted, see Additional Resources for full text):

CME Group is implementing end-to-end technology changes to support increased price granularity. Currently, CME Group systems support a maximum of 7 decimals. With this initiative, products with up to 9 decimals may be listed and traded. On Sunday, January 13, 2019 (trade date Monday, January 14), pending regulatory approval, the 2-Year Treasury Note futures, all 2-Year Treasury Future Spreads (including Calendar Spreads, Tail Spreads and Inter-Commodity Spreads with a 2-Year Treasury Future) along with the futures portion of covered options UDS, will move from 7 decimals to 8 to support trading at 1/8 of 1/32.

A production test instrument for the 2-Year Treasury Note futures is currently available on CME Globex to give customers the ability to confirm system readiness for the introduction of 8-digit decimal price precision.
