ICAP Plc is seeking U.S. oversight of an overseas swap-trading platform a month after Wall Street lobbying groups sued the Commodity Futures Trading Commission (CFTC) trying to curb the agency's international reach.

ICAP, the world's largest broker of transactions between banks, wants to register a London-based platform with the CFTC to follow Dodd-Frank Act rules for swap-execution facilities (SEFs) and provide access to U.S. traders, according to an application submitted this month. The brokerage is the first large SEF platform to seek U.S. approval for an overseas-based entity.

"In the event of market demand to facilitate SEF liquidity across Europe and the European markets, ICAP Derivatives Limited should allow us to operate one liquidity pool leveraging both our U.S. and London capabilities," Peter Best, chief operating officer of ICAP's SEF, said in an email. The platform will support trading in interest rate swaps in U.S. dollars, euros, and pounds sterling, Best said.
