CME to Extend June 10 Floor Trading Session for Interest Rate, FX Products

CHICAGO, June 9 /PRNewswire-FirstCall/ -- Chicago Mercantile Exchange Inc. (CME) today announced that it will extend its Thursday, June 10 open outcry trading (pit) session for interest rate and foreign exchange products by a half hour until 2:30 p.m. Central Time to accommodate the new release time for the Producer Price Index (PPI) data.

However, the release time was changed to 2 p.m. Central Time Thursday in response to the Friday closing of the federal government for the National Day of Mourning for the death of former President Ronald Reagan.

As previously reported, CME's trading floors will be closed on Friday, June 11 for the National Day of Mourning, while GLOBEX markets will close for trading at 8 a.m.
