Material Changes Versus Prior Period
- Capital Reduction: Total risk-based capital decreased by approximately ¥941.6 billion year-over-year, driven by a reduction in Tier 2 capital (down ¥749.4 billion) and Tier 1 capital (down ¥171.7 billion). This was partially offset by a significant reduction in risk-weighted assets (down ¥6,060.3 billion).
- Improved Asset Quality: Total actual credit losses decreased by ¥233.2 billion compared to the prior period, attributed to improved customer credit ratings and reversals of provisions related to problem loans at Mizuho Corporate Bank.
- Securitization Exposure: The balance of foreign currency-denominated securitization products held by banking subsidiaries decreased from ¥889 billion (March 2008) to ¥693 billion (September 2008).
- Equity Exposure: Total equity exposure in the banking book decreased from ¥5,911.3 billion to ¥4,458.4 billion.
Outlook, Risks, and Unusual Items
Impact of Global Financial Market Dislocation:
- Realized Losses (1H FY2008): Total realized gains/losses related to the financial crisis were a net loss of ¥72 billion. This included ¥59 billion in losses from sales and devaluation of securitization products by banks and ¥13 billion in trading losses by Mizuho Securities.
- Subprime Exposure: The Group reported no warehousing loan business related to U.S. subprime mortgage loans. Loans to U.S. mortgage lenders totaled ¥48 billion, with all lenders holding investment-grade ratings.
- US Monoline Exposure: Approximately ¥22 billion of securitization products and ¥16 billion of loan commitments were guaranteed by U.S. monolines. While some monolines were downgraded to non-investment grade, the Group reported no particular concerns regarding the underlying assets as of September 30, 2008.
- Outlier Framework: Under the Basel II outlier framework for interest rate risk, the loss ratio to broadly-defined capital was 6.2% as of September 30, 2008, well below the 20% threshold that would trigger outlier status.
Risks and Contingencies:
- Preferred Securities: The Group holds various non-cumulative perpetual preferred securities issued by overseas Special Purpose Companies (SPCs). Dividends on these securities are subject to suspension if the Group fails to pay common dividends or if capital adequacy ratios fall below minimum requirements.
- Counterparty Risk: Credit derivatives (CDS) related to securitization products had a notional amount of ¥370 billion as of September 2008, with significant exposure to U.S. monolines (¥85 billion notional).
Investor Verification Checklist
- Capital Adequacy Trends: Verify the sustainability of the 11.45% capital adequacy ratio given the reduction in total risk-based capital.
- Securitization Valuation: Review the specific unrealized losses (¥87 billion) on foreign currency-denominated securitization products held by banking subsidiaries.
- Monoline Exposure: Assess the credit risk associated with the ¥85 billion notional amount of CDS contracts referencing U.S. monolines, given the downgrade of some counterparties.
- Asset Quality Reversals: Confirm the drivers behind the ¥233.2 billion decrease in actual credit losses to ensure it reflects genuine asset quality improvement rather than accounting adjustments.
- Preferred Stock Dividends: Monitor the Group's ability to pay common dividends, as this is a mandatory trigger for paying dividends on the Group's preferred securities issued by SPCs.
