The Commodity Futures Trading Commission has issued an order authorizing the Chicago Mercantile Exchange (CME) to clear certain over-the-counter swaps in corn, wheat and soybeans in response to a petition filed in April 2008 by the CME and the Chicago Board of Trade (CBOT). The CFTC order also permits the CME and futures commission merchants (FCMs) clearing such swaps through the CME Clearing House to hold customers’ positions in these swaps and related funds in a customer segregated funds account. Under the CFTC order, the swaps may only be entered into by “eligible swap participants” pursuant to Part 35 of the CFTC’s regulations and will be listed by the CBOT for clearing (but not trading).
