Talent outflows persist at Switzerland's second-largest lender, this time with the reported departure of a senior mergers and acquisitions banker.

Hong Kong-based managing director and APAC M&A deputy head Christopher Chua has resigned from Credit Suisse, according to a «Bloomberg» report citing unnamed sources. Chua was named to the role in September in addition to his existing responsibilities as Grater China head of M&A. 

Chua is expected to join HSBC to lead its M&A business in Asia.

Credit Suisse is facing pressure from all fronts including the outflow of talent across businesses. In addition to its investment banking unit, it has also lost top executives from its private banking arm including, most recently, the exit of Asia deputy wealth head Young Jin Yee after two decades with the troubled Swiss lender.
