Mizuho is roughly tied with its megabank peer Sumitomo Mitsui Financial Group, or SMFG (8316 JP) for the status as Japan's second-largest bank after Mitsubishi UFJ Financial Group, or MUFG (8306 JP). As of March 31, 2018, Mizuho's market share of domestic loans was 8.4%, compared with 7.2% for SMFG and 9.4% for MUFG. In Japan, Mizuho has more of a corporate focus than SMFG, which has a larger retail business. Its overseas weighting is slightly smaller than that of MUFG. Unlike its two Japanese megabank peers that own foreign banks outright or hold noncontrolling stakes in local banks overseas, Mizuho expanded in recent years beyond its traditional Japanese borrowers, mainly through its core banking and securities units, focusing on the financing needs of global multinational corporations.
