What exactly changed at Japan Post Bank and when does it start?

Japan Post Bank will raise the ordinary deposit rate to 0.3% from 0.2%. The new rate takes effect on February 9, 2026. It follows the Bank of Japan’s December 19 policy rate increase. Savers will earn more interest while keeping full access to funds in their everyday accounts.

Why did Japan Post Bank raise rates now?

The move reflects the BoJ rate hike impact flowing into retail banking. As policy rates rise, banks adjust deposit pricing to remain competitive and retain funding. The Japan Post Bank interest rate change sets a visible benchmark that other banks may reference when updating ordinary and time deposit rates.

How does this affect bank profitability in Japan?

Higher deposit rates lift funding costs. If banks cannot reprice loans and securities as quickly, net interest margins may narrow. Competitive pressure could intensify as rivals match 0.3%. Banks with strong fee income and disciplined costs may cushion the impact better than lenders relying mainly on spread income.

What should savers in Japan consider doing now?

Review cash balances, compare deposit rates, and match money to goals. Keep emergency funds liquid in ordinary deposits. For planned expenses, consider a simple time-deposit ladder to seek higher yields while managing access. Recheck rates regularly because banks can adjust pricing as market and policy conditions evolve.
