Blythe Masters, JP Morgan’s commodities chief, has joined an advisory committee of the Commodity Futures Trading Commission, the agency said.

Masters, 44, a veteran of the swaps industry, will sit on a global markets committee that will meet next week to discuss the overseas application of the CFTC's rules. The committee also includes executives from Citigroup and Goldman Sachs. Banks have largely opposed the CFTC's efforts to extend its swaps rules overseas.
