Suing the Commodity Futures Trading Commission didn’t prevent CME Group, the nation’s largest futures exchange operator, from being registered as a Swap Data Repository (SDR).

CME was named by the Commission last week as the third entity to gain that designation. The category of CFTC registered entities was created by the Dodd-Frank Act to collect and maintain swap transaction data and information. CME was provisionally registered as a swap data repository for the interest rate, credit, foreign exchange, and other commodity asset classes.
