Mizuho is one of Japan's three megabanks, providing banking, trust, and securities services. The group operates through three primary subsidiaries: Mizuho Bank, Mizuho Trust & Banking, and Mizuho Securities. Mizuho generates revenue through net interest income from lending, fees from investment banking and asset management, and trading revenue. The company serves retail depositors, small businesses, large corporations, and institutional investors. Its Retail & Business Banking segment offers loans and investment products in Japan, while the Corporate & Investment Banking (CIB) and Global CIB units provide financing, underwriting, and M&A advisory services to domestic and international clients. The Global Markets segment handles sales, trading, and the group's investment portfolio. Mizuho's strategy focuses on expanding digital retail services and capturing Japanese household savings as they move into tax-advantaged investment accounts. Internationally, Mizuho is expanding its capital markets presence in the U.S. and Asia, including through acquisitions in India and new subsidiaries in China. The company also operates a transaction banking unit for cash management and a research arm for macroeconomic analysis. Mizuho argues that its integrated model, which combines banking and securities functions, allows it to serve corporate clients across their entire lifecycle.
