Insights
TL;DR: Capital ratios edged higher quarter-over-quarter; capital levels rose but RWAs also increased, keeping the change modest for valuation impact.
The consolidated Total Capital Ratio improved to 17.93% and Tier 1 to 15.96%, driven by a ¥320.1bn increase in total capital. However, risk-weighted assets grew by ¥1,067.1bn, which lifted required capital by ¥85.3bn. For investors, these figures signal a slightly stronger capital buffer but not a material shift in solvency or earnings outlook based solely on this release.
TL;DR: Solvency metrics improved modestly with higher CET1 and Tier 1; rising RWAs offset part of the improvement, increasing regulatory capital needs.
CET1 rose to 13.35% and Tier 1 to 15.96%, which supports regulatory compliance headroom. The ¥1,067.1bn rise in RWAs to ¥72,911.5bn increased the total required capital to ¥5,832.9bn, reducing the net margin of improvement. The data are material for capital adequacy monitoring but do not indicate emerging solvency stress.
