IMF sees Bank of Japan rate hikes continuing toward neutral setting
BOJ rates to rise further

Japan faces slower economic growth as policymakers balance persistent inflation pressure with the effects of higher energy costs and currency weakness. The International Monetary Fund says the Bank of Japan is likely to keep raising interest rates gradually toward a neutral setting even as growth is projected to slow.

Highlights

  • IMF projects Japan GDP growth slowing to 0.7% in both 2026 and 2027, down from 1.2% last year, as energy shock and policy normalization take effect.
  • Bank of Japan raises interest rates to a 31-year high of 1.25% in September, with further tightening likely to counter inflation risks exceeding its 2% target.
  • IMF notes heightened Asian currency volatility, with Japan and the U.S. jointly intervening to support the yen, and advises that foreign exchange intervention be used only during disorderly market conditions.

IMF outlook on Japan rates and growth

As reported by Reuters, citing the International Monetary Fund in its World Economic Outlook, Japan's economy is projected to slow to 0.7% in 2026, with fiscal support measures partly cushioning the impact of higher energy prices. The IMF says growth stabilizes at that level in 2027 as the energy shock dissipates and monetary policy gradually normalizes.

The 2026 forecast follows 1.2% expansion last year. The IMF also expects Japan's economy to grow 0.7% in 2027.

The Bank of Japan raises interest rates to a 31-year high of 1.25% in September and signals readiness to keep tightening policy to prevent inflation from overshooting its 2% target. Japan's reliance on imported fuel and raw materials leaves the economy particularly exposed to the inflationary effects of the energy shock and a weak yen.

Currency volatility and broader policy implications

The IMF says central banks can look through the direct and short-term indirect effects of an inflation shock only if the shock is temporary. Even when that approach is appropriate, it says policymakers may still need to raise nominal interest rates if inflation expectations strengthen, in order to keep real borrowing costs steady.

The report says exchange rates experience high volatility, especially in Asia, prompting intervention by some countries, including a joint Japan-U.S. operation to support the yen. The IMF adds that economies should generally allow exchange rates to move flexibly to absorb external shocks, but temporary foreign exchange intervention can be considered if market moves become disorderly or threaten price stability and financial stability.

Our earlier report on Singapore’s strong-currency policy explained why policymakers are resisting calls to weaken the Singapore dollar, prioritizing stability and imported-inflation control even if it raises costs for exporters. It also outlined how the Monetary Authority of Singapore’s exchange-rate-based framework manages the currency against a trade-weighted basket, keeping the focus on fundamentals rather than using interest rates as the main lever.
