Material Changes vs. Prior Period
- Capital Strength: All capital ratios (CET1, Tier 1, Total) improved year-over-year, driven by an increase in CET1 capital of approximately 327 billion yen and a reduction in Risk-Weighted Assets of approximately 1.45 trillion yen.
- Liquidity: The LCR increased significantly from 121.3% in the prior quarter to 130.1%, exceeding the 100% regulatory minimum. This was supported by a decrease in net cash outflows despite a slight reduction in HQLA.
- Asset Quality: Defaulted loans and debt securities decreased from 653,659 million yen (Mar 2018) to 570,771 million yen (Sep 2018), reflecting a reduction in non-performing assets.
- Consolidation: The number of consolidated subsidiaries decreased from 130 to 125 between September 2017 and September 2018.
Outlook, Risks, and Contingencies
Management Commentary: The group states that its Consolidated LCR surpasses the final regulatory standard and remains stable. There are no significant changes in the composition or geographic distribution of HQLA, and no significant currency mismatches affecting funding conditions are expected.
Risks and Contingencies:
- Interest Rate Risk (Banking Book): Under a parallel up shock scenario, the potential decrease in Economic Value of Equity (EVE) was 807,937 million yen as of September 30, 2018. The group monitors this against the "outlier" criteria (20% of Tier 1 + Tier 2 capital).
- Market Risk: Value at Risk (VaR) for trading portfolios averaged 7,465 million yen (10-day, 99% confidence) for the period ended September 30, 2018. Stressed VaR averaged 22,684 million yen.
- Counterparty Credit Risk: Significant exposure exists in derivatives and securities financing transactions, with total RWA for counterparty credit risk at 4,224,033 million yen.
- Securitization: The group acts as an originator, sponsor, and investor in securitization programs, with total exposures as an investor totaling 3,331.3 billion yen (Sep 2017 data provided in detail; Sep 2018 data indicates continued activity).
Key Facts for Investor Verification
- Verify the sustainability of the 130.1% LCR given the reduction in HQLA from the previous quarter.
- Monitor the trend in defaulted exposures, which have declined but remain at 604.8 billion yen.
- Assess the impact of the reduction in Risk-Weighted Assets (from 61.7T to 60.2T yen) on future capital generation and return on equity.
- Review the composition of the 216.9 trillion yen in total exposures for the leverage ratio to understand off-balance sheet commitments.
- Confirm the stability of the CET1 ratio above the 12.62% level, considering the 2.64% total buffer requirement.
