Mizuho FG’s CET1 ratio climbs to 13.76% as capital base grows

The megabank earlier announced that it has achieved 90% of its profit target.

Mizuho Financial Group’s (MFG) consolidated common equity tier 1 (CET1) capital ratio is at 13.76% as of 31 December 2025, 0.53 percentage point (ppt) higher than in March 2025.

Mizuho Bank’s CET1 capital ratio, meanwhile, rose to 12.44%, or 1.02 ppt higher than the 11.42% in March, according to an announcement.

MFG earlier announced that it has achieved 90% of its profit target in the nine-month period that ended in December 2025, with its profit at $6.4b (JPY1.02t).

“We think the additional share buyback is a positive sign that Mizuho management is confident its capital base is growing and that there is flexibility to increase shareholder returns,” according to an analyst note by Morningstar.
