Credit Suisse has rehired a senior banker who left three years ago after helping build its equity derivatives business in Europe, in a key post driving the growth of the unit.
Thibaut de Gaudemar will rejoin the Swiss bank in November as vice-chairman of its capital markets solutions group in Europe, the Middle East and Africa, according to a memo sent to staff on October 27.
