Capital Components (Group Consolidated):
- Tier 1 Capital: 4,660.1 billion yen (Decrease of 220.0 billion yen).
- Tier 2 Capital: 3,333.0 billion yen (Increase of 111.1 billion yen).
- Total Risk-based Capital: 7,679.6 billion yen (Decrease of 28.7 billion yen).
- Risk-weighted Assets: 66,249.1 billion yen (Increase of 376.2 billion yen).
Material Changes
From March 31, 2008, to June 30, 2008, the Group experienced a decline in both its Capital Adequacy Ratio and Tier 1 Capital Ratio. The primary driver for the decline in ratios was a significant reduction in Tier 1 Capital (down 220.0 billion yen) coupled with an increase in Risk-weighted Assets (up 376.2 billion yen). While Tier 2 Capital increased, it was insufficient to offset the drop in Tier 1 Capital and the expansion of risk-weighted assets.
Notably, Mizuho Trust & Banking saw the largest percentage decline in its Capital Adequacy Ratio (down 2.18 percentage points), driven by a 64.7 billion yen decrease in Tier 1 Capital.
