Adrian Hyde, former U.S. head of credit derivatives trading at TD Securities in New York, has joined Banc of America Securities as managing director and head of the firm's U.S. credit derivatives flow trading operation. Hyde's appointment follows the move by Sean Bonner, who had formerly headed the desk, to Wachovia Securities earlier in the summer as managing director and head of high-grade credit-default swap trading. At BofA Hyde reports to Dan Caldwell, managing director and global head of credit derivatives trading in Charlotte, said Jeff Hershberger, spokesman in New York. Caldwell declined comment. Hyde, who left TD Securities last month (DW, 8/18), did not respond to messages.
