Hang Seng Bank will get its first female chief executive when HSBC's Margaret Leung Ko May-yee is seconded to the subsidiary in May to replace retiring Raymond Or Ching-fai, sources said.
Mrs Leung, 56, HSBC's general manager and global co-head of commercial banking, would succeed Mr Or and become the bank's first female chief executive in the lender's 75-year history, the sources said.
Hang Seng is 62 per cent owned by HSBC Holdings, which has often seconded senior managers to head its subsidiary.
The promotion will be the second 'first' for Mrs Leung. In 2005, she became the first Chinese woman in HSBC's 143-year history to become a group general manager.
In her current role, she is responsible for HSBC's relationship with all middle-market corporations and small and medium-sized enterprises in the Asia-Pacific and Middle East markets.
Mrs Leung joined the bank in 1978. She graduated in 1975 from the University of Hong Kong with a bachelor's degree in economics, accounting and business administration.
