John Lima, a U.S. dollar spot and options trader for Deutsche Bank in London, has moved to the firm's New York office to trade short-dated options. Lima's move is part of the bank's effort to consolidate its short-dated options trading into one book. The new book combines the old risk books of mortgage options, Treasury options, agency options and shorter-dated (less than six months) swaptions, according to Kinol. He expects the aggregation of risks to pump up liquidity and reduce risks by netting positions against each other. Lima will be replaced internally, according to Kinol.
