IMF Forecasts BOJ Will Gradually Raise Rates Toward Neutral
nashnova research
The IMF's latest World Economic Outlook projects the Bank of Japan will keep hiking toward a neutral rate even as growth slows to 0.7% — signaling that taming inflation outranks supporting growth.
Growth is slowing — why keep raising rates?
The IMF forecasts Japan's GDP growth falling from 1.2% in 2025 to 0.7% in 2026, holding at that level through 2027.
Yet the BOJ has already lifted its benchmark rate to 1.25% in September — a 31-year high — and signaled further tightening ahead.
This means → the BOJ's priority is clear: cap inflation first, support growth second. Letting prices run would cost far more than a short-term slowdown.
Why is Japan especially vulnerable to energy shocks?
Japan relies heavily on imported fuel and raw materials. A weak yen keeps pushing import costs higher.
In plain terms = the weaker the yen, the pricier imports become, the faster prices rise — a self-reinforcing loop.
The IMF notes that whether the BOJ can "look through" energy-driven inflation depends on whether the shock is temporary. If inflation expectations start climbing, the bank may need to raise nominal rates just to keep real borrowing costs steady.
The yen is volatile — how are policymakers responding?
The IMF flags sharply increased volatility across Asian FX markets. Japan and the U.S. have already intervened jointly to support the weakening yen.
The IMF's stance: exchange rates should float flexibly to absorb external shocks, but intervention is warranted when markets turn disorderly.
Specifically, temporary FX intervention is justified when depreciation becomes self-reinforcing, liquidity dries up, or currency swings threaten price stability through large pass-through effects.
What determines the next rate move?
The timing and size of the BOJ's next hike will hinge on energy prices and the path of inflation expectations.
This reflects a larger shift: Japan is moving from "zero-rate outlier" back into the global central-bank mainstream — but the pace is set by two variables, energy and the yen.
In plain terms = oil prices and the yen are the BOJ's accelerator and brake.
