Credit Suisse has appointed an executive from the European Central Bank to oversee its communications effort, as it executes a changing of the guard following the ousting of then-chief executive Tidjane Thiam.

Christine Graeff, the ex-ECB communications chief, becomes Credit Suisse’s group head of corporate communications and deputy global head of human resources.

She replaces the bank’s former head of investor relations and communications Adam Gishen, who was reportedly close with Mr Tidjane and left the bank earlier this year. Both men left the bank earlier this year.
