What they do

Mizuho Financial Group operates primarily as a national commercial bank, offering a range of financial services including corporate and retail lending, investment banking, asset management, and treasury services. The group's retail portfolio is mainly housing loans to individuals, while corporate lending and foreign operations are major revenue sources. It also engages in trading activities, including derivatives and securities, with a notable portfolio of Japanese agency mortgage-backed securities.

• Retail portfolio — Primarily housing loans to individuals; obligor classification based on past due status (e.g., reclassified to watch if past due more than 30 days).
• Trading and investment securities — Includes trading account assets/liabilities, CLOs, convertible bonds (Level 3), and agency MBS (Japanese agency MBS fair value 281,815 million at March 2026, issued by Japan Housing Finance Agency).

Recent performance

Fiscal year ended March 2026 revenue increased to ¥8.79 trillion from ¥8.17 trillion in 2025, while net income rose to ¥1.16 trillion from ¥593.39 billion, with diluted EPS up to ¥466.09 from ¥234.52. Operating cash flow turned negative at -¥1.78 trillion, down from a positive ¥59.04 billion in the prior year. Charge-offs increased to ¥272,985 million from ¥224,941 million, driven mainly by a downgrade in obligor rating at a domestic corporate borrower. Total assets stood at ¥294.90 trillion with shareholder equity of ¥10.86 trillion at March 31, 2026.

Strategy

While the excerpt does not explicitly state a strategy, management has focused on managing credit risk with macroeconomic-sensitive models for allowance for credit losses. They have also responded to regulatory changes, including an increase in the effective statutory tax rate to 31.52% starting fiscal year ending March 2027, and have accounted for capital conservation and countercyclical buffers in regulatory ratios. The group has also been dealing with loan modifications, primarily term extensions and interest rate reductions, which extended weighted-average life and reduced interest rates to support borrowers.

Risks

• Credit risk from domestic corporate borrowers — A downgrade in obligor rating at a domestic corporate borrower led to a significant increase in charge-offs in fiscal 2026.
• Tax rate increase — The effective statutory tax rate will increase to 31.52% from 30.62% beginning fiscal year ending March 2027, which could reduce future net income.
• Derivative and repurchase exposure — Large derivative assets/liabilities subject to master netting agreements, and repurchase/resale agreements with netting terms, expose the group to counterparty and market risk.
• Macroeconomic sensitivity of loan loss allowances — Allowance for credit losses relies on macroeconomic scenarios, making them sensitive to economic downturns and affecting earnings.

Outlook

Management has noted an increase in the statutory tax rate from fiscal 2027, which will impact future earnings. The group holds net deferred tax assets that may expire if not utilized, particularly foreign tax credit carryforwards that expire in fiscal year ending March 2027. The increase in off-balance-sheet unfunded commitments (from ¥58 billion to ¥190 billion) suggests continued investment commitments, but also potential future funding needs.
