LCH.Clearnet Group says it has reached a deal to acquire International Derivatives Clearing Group. The move comes as regulators complete rules to require most over-the-counter derivatives to be processed through clearinghouses. London-based LCH.Clearnet is expanding its U.S. operations in clearing interest-rate swaps through SwapClear. "This is all about making SwapClear a more attractive clearing venue in the U.S. for end users," said Richard Perrott of Berenberg Bank. "This will make it easier to organize cross-margining and capital offsets."
