Nasdaq OMX is planning to add to the portfolio of rate swaps it clears after splitting its exchange and clearing businesses as mandated by regulation, according to Hans-Ole Jochumsen, the executive vice president of Nasdaq's Nordic transaction services. "After the summer break we've been getting more business in every day," Jochumsen said. "Probably within two months we will have another clearing bank and that will boost volume too. We have another one coming sometime in the fourth quarter. We are building in close cooperation with the five large Nordic banks."
