On November 18, the CFTC unanimously approved a final rule amending certain parts of its regulations relating to the execution of “package transactions” on swap execution facilities (SEFs) and the resolution of error trades on SEFs. The final rule amends part 37 of CFTC regulations to allow the swap components of certain categories of package transactions to be executed on SEF but through flexible means of execution rather than through the required methods of execution for “required transactions.” Release.
