GENEVA, May 15 (Reuters) - The CME Group ( CME ) and

Euronext exchanges are planning to launch joint futures

contracts on the spread between Chicago Board of Trade wheat and

Euronext milling wheat futures prices, three sources told

Reuters on Wednesday.

There will be two products, one cleared by CME and traded in

dollars, the other cleared by Euronext and traded in euros, the

sources said on the sidelines of the GrainCom conference in

Geneva.

CME and Euronext both declined to comment.

The new products will also allow traders who are not

registered on both the CBOT and Euronext markets to trade the

difference, the sources said.

The contracts are still to be agreed officially with some

details to be confirmed.

The U.S. exchange launched European wheat futures in 2016 as

a direct competitor to Euronext but closed them two years later

due to a lack of activity.

It suspended its Black Sea wheat and corn and Ukraine wheat

futures in August of last year.
