De Ferrari, who worked at Credit Suisse between 2002 and 2018, joins after a stint leading Australian wealth-management company AMP.
His appointment comes after Credit Suisse announced a new strategy to curb its investment bankers and plough money into looking after the fortunes of the world's rich.
