Japan raises policy rate to 1% as inflation reshapes households and retirement savings

The Bank of Japan ended its negative‑rate era in June 2026, lifting the policy rate to around 1% – the highest level in three decades. The move follows global supply constraints, a weaker yen and a shift from cost‑push to demand‑pull inflation. Higher rates are expected to curb excessive yen depreciation, temper energy and food price spikes, and increase fiscal revenues, but they also raise borrowing costs for firms and households.

For companies, larger businesses can pass on price hikes, while smaller firms face tighter margins and a risk of “inflation‑induced bankruptcies.” Households experience divergent impacts: workers at firms with strong wage growth can maintain purchasing power, whereas low‑paid, part‑time or pensioners see real incomes fall. Mortgage payments on variable‑rate loans rise as short‑term prime rates climb, prompting a shift toward higher‑yield savings instruments.

In the retirement‑savings arena, the iDeCo lump‑sum withdrawal rule was altered. From 2026 the interval between a 60‑year‑old’s iDeCo payout and the next retirement‑benefit payment extends from five to ten years, limiting the tax advantage previously available to a narrow group. Financial advisers note that the new rule, combined with rising interest rates, reduces the appeal of early lump‑sum withdrawals and encourages longer‑term, inflation‑linked investment strategies.
