The Commodity Futures Trading Commission proposed amendments to certain of its rules to accommodate the execution of package transactions and block trades and the resolution of error trades on swap execution facilities in a more flexible manner than prescribed by existing rules. Among other things, the CFTC proposed to authorize (1) the components of certain categories of package transactions to be executed on SEFs through flexible means other than the mandatory methods for transactions required to be executed on a SEF; (2) block trades to be executed through non-order book methods of executions; and (3) SEFs to apply flexible approaches to error trades resolution that do not mandate prescribed methods of execution for required transactions. These matters are already subject to some relief by the CFTC through no action letters.
