Japan’s neutral interest rate is rising, but not by much
We estimate that Japan’s nominal neutral interest rate – the rate consistent with monetary policy that is neither stimulative nor restrictive – has risen somewhat since 2022, marking a striking reversal from its decades-long slide. More importantly, we project it to continue rising gradually, to around 1% by 2030 from 0% in 2023.
What you will learn:
- Higher inflation expectations are one of the main reasons behind the recent increase in the nominal neutral rate. We believe that inflation expectations will continue to slowly edge up in the coming years amid robust wage gains, contributing to the projected neutral rate’s rise.
- Stripping out inflation expectations, the real neutral rate has risen only modestly in recent years. We think Japan’s demographic headwinds and weak productivity growth all but banish a sustained return to positive real neutral rates throughout our forecast to 2050. But in the next few years, increases in net foreign assets and the Bank of Japan’s step down in quantitative easing are likely to drive the rate slightly higher.
- Neutral rate estimates are inherently uncertain. Still, our approach provides a framework that can inform our view of the path for long-run interest rates, and our sensitivity and scenario analyses offer a useful gauge of the risks around our estimates.

How far monetary normalization can go in Japan after today’s rate hike
The Bank of Japan raised its policy rate by 0.25ppts to 0.75% at its meeting on Friday, which the dovish government had to accept in face of yen weakening pressures. Although we still project another hike to a terminal rate of 1% in mid-2026, the BoJ could find it more difficult to justify this if inflation eases towards 2% in H1 2026 and pressure on the yen fades.

Japan’s fiscal policy will remain loose, which increases risks to debt sustainability
We've changed our fiscal outlook for Japan in our December forecast round. We now expect the new government to set a primary deficit close to that of 2024, at 2%-3% of GDP for 2025-2027, instead of restoring a balanced budget by taking advantage of strong tax revenue. We assume higher bond yields will force the government to take measures to reduce the deficit from 2028.

Japan’s politics add uncertainty to BoJ policy outlook
The Bank of Japan (BoJ) kept its policy rate at 0.5% at its October meeting, after a 7-2 majority vote. Two board members again voted for a rate increase. We believe the BoJ will hike in December to 0.75% as incoming data confirm that the economy is performing in line with the bank's forecasts in its quarterly outlook. However, there's a material chance of a delay.
