Japan Exchange Group Inc. has revised its guidelines on derivatives trading, following a series of bond futures manipulation scandals at Nomura Holdings Inc. and other major global banks.

The amendment seeks to clarify the criteria for reviewing derivatives transactions so that financial firms can establish more effective oversight themselves of trading in products including Japanese government bond futures.
