Mizuho Financial Group Inc. plans to encourage equity research analysts to become investment bankers as the megabank competes for business arranging share sales and advising on mergers.

Mizuho Securities Co. will offer its analysts the opportunity to switch jobs so the company can tap their knowledge about industries and the equity market to advise clients, said Yohei Osade, global head of Asian equities.

The firm plans to hire analysts to fill the vacated roles, Osade, 46, said in an interview Aug. 25.
