Société Générale on Friday appointed Didier Valet as its chief financial officer, filling the gap in the French bank’s senior ranks created when Frédéric Oudéa was promoted to be chief executive last month.

Mr Valet, a former banking analyst and previous head of SocGen’s investor relations department, will play a pivotal role in rebuilding the bank’s credibility with investors and regulators following the rogue trading scandal involving Jérôme Kerviel.
