Credit Suisse’s London-based co-head of global securities has been promoted to co-head of the investment bank and handed two additional regional roles, as the firm reshapes its structure.

The Swiss bank today announced that Gael de Boissard would become co-head of the investment banking division, with responsibility for fixed income, amid a raft of structural changes. Under the revised structure, private banking and asset management will be combined to form a single division, which will also house the sales and trading business in Switzerland.
