Credit Suisse is in the middle of what it has described as a "transition" year with a new CEO, restructuring aimed at curtailing risk-taking in investment banking and the bulking up of wealth management. Its shares have declined nearly 40% in 2022.

The company last month launched its second strategic review in less than a year to evaluate options for its securitised products business to attract third-party capital.

In May, when Reuters first reported about the strategic review, David Herro of Harris Associates said in an interview that there was no need for the bank to raise fresh equity capital.
