Expiration Time Change for CME FX Options

Everything about CME FX options remains the same, except the time they expire. Expiry is changing from 2 p.m. Chicago to 10 a.m. New York Time.

The Logic

In 2017, CME Group surveyed participants across the market and around the world. We wanted to determine if aligning our market more closely with the OTC market convention, and moving to 10 a.m. New York, would make it easier to access the liquidity, capital efficiencies and security of our markets.

Of all respondents, 71% stated it would, and requested we make this change to our market structure. 

Simply put, the market asked, and we delivered.

The Convention

CME Group is changing our expiration time to 10 a.m. New York, to bring our FX options in line with the primary OTC market convention.

All the codes you use today will remain the same.

CME Group systems will continue to refer to the Chicago time convention for consistency. Thus 10 a.m. New York (10 a.m. ET) will appear as 9 a.m. CT in our clearing and trading systems.

The Schedule

The expiration time will change to 10 a.m. New York (10 a.m. ET) for all contracts expiring after June 7, 2019, nearly a year from now. 

However, some contracts will begin trading sooner. The first contract affected will be the September 2019 quarterly, which is listed, and starts trading, on September 9, 2018. Market participants need to be aware of the contract listing schedule.

The Fix

The 10 a.m. New York (9 a.m. CT) fix value will determine CME Group’s FX option auto-exercise process.
