A former head of European prime brokerage at UBS has returned to banking with a similar senior role at Bank of America Merrill Lynch – a move that will reunite her with her former boss at the Swiss bank.

Martina Slowey, who was most recently chief operating officer at the now defunct hedge fund Edoma Partners, has joined Bank of America Merrill Lynch as head of prime brokerage for Europe, the Middle East and Africa, according to an internal memo from Stuart Hendel, global head of financing products.
