Harry Culham, former big cheese FX at Merrill Lynch, has resurfaced far quicker than most people will have expected at CIBC. In his new role as managing director and head, fixed income and currencies (FIC), Culham will be based in Toronto. The job marks a return to his roots for Canadian national Culham, who worked at CIBC earlier in his career from 1990 to 1994 as an FX dealer in Toronto.
