In his new role, Winterburn will continue advising UK clients and additionally oversee Julius Baer’s advisory team in London. He started on 10 February and said the goal is to “materially build out” services for HNWs as an area "increasingly neglected by wealth management".

This includes carrying on designing and pitching tailor-made investment solutions for clients based on their individual requirements, Winterburn said. The Swiss firm's head of products and services, Ed Raymond, said the group has put “significant” investment into a proprietary tool making it easier for executives to maintain personal connections with clients.

Winterburn has spent 14 years in financial services and joined Julius Baer in 2017 from a director role at Coutts. He has also served in senior roles at HSBC Private Bank and Citi Private Bank.

Earlier this month, the Swiss group reported a mixed bag of financial results with rising AuM and net new money, but also a rise in costs and a sharp hit to net profits. The bank said that it is cutting costs and shutting its Bahamas booking centre.
