The bank is currently looking for someone to replace Haimes, who joined from JP Morgan in 2012, as managing director and head of family office and institutional clients.

Dembinski headed up Credit Suisse's ultra-high net worth team before assuming the leadership of the UK domestic private banking team in 2012. He has been replaced by Fiona Paulus, who previously led the bank's ultra-high net worth team for Russia, Eastern Europe, Israel and central Asia, based in Zurich. Before joining Credit Suisse in October last year, Paulus worked at CIBC World Markets.

In its recent results statement for 2015, Credit Suisse's Swiss universal banking arm logged a 29 per cent year-on-year fall in unadjusted pre-tax private banking income to SFr869 million ($881 million). On an adjusted basis, pre-tax income was SFr821 million, down from SFr790 million.
