HSBC has hired Matthew Wank, an interest-rate derivatives marketer at Credit Suisse First Boston, in a similar role. Wank will be responsible for marketing to banks and insurers, according to an official. It could not be determined whether he is filling a newly created seat. Pamela Plehn, spokeswoman at HSBC in New York, declined comment. John Gallagher, spokesman at CFSB in New York, confirmed the departure.
