Hirst joined the bank’s Geneva office in 2012 as regional head of private banking before taking the helm of the Swiss business. He previously spent three years at Credit Suisse where he led the firm's UK and international private banking business. Before that, he worked at Deutsche Bank as head of wealth management in the Middle East and Africa.

A spokesperson for Standard Chartered declined to comment on the departure.

In its recent results statement for the first half of 2016, Standard Chartered reported a profit attributable to ordinary shareholders of $394 million, falling from $1.462 billion a year ago. However, it bounced back from the loss of $3.822 billion in the second half of 2015.

In July, the bank, which earns the bulk of its revenues in regions such as Asia, appointed International Monetary Fund executive José Viñals as its new chairman. He will succeed Sir John Peace on 1 December.
