Deutsche Bank has hired John Santoro to be its "short-coupon" Treasury bond trader, trading primarily two-year notes. Santoro will replace Jeff Gray, who was released last week. He declined to comment when reached at his desk. Gray had already left the firm and was unavailable for comment late last week. Ted Meyer, a Deutsche Bank spokesman, says Santoro will report to fixed-income chief Thomas Paul. His first day was last Monday. His last job was at SG Cowen, where he ran the government bond desk from 1998 until the first week of April, when he resigned. Late last year, SG Cowen gave up its primary dealership.
