CHICAGO, Oct. 15 /PRNewswire-FirstCall/ -- CME Group, the world's largest and most diverse derivatives marketplace, today announced the launch of cleared over-the-counter (OTC) swaps on the S&P GSCI® Crude Oil Excess Return and the S&P GSCI Gold Excess Return Indices, as well as Forward contracts for the S&P GSCI Excess Return Index, all scheduled to begin trading November 2. Clearing will be available through CME ClearPort®, a set of flexible clearing services open to (OTC) market participants to substantially mitigate counterparty risk and provide neutral settlement prices across asset classes.
