Investment bank Citi now believes the Bank of Japan (BoJ) will raise its interest rate this June, marking a significant shift in expectations for one of the world's major central banks.
This updated outlook is driven by a combination of powerful signals suggesting the BoJ needs to act sooner rather than later. The reasoning can be broken down into a few key areas.
First, the BoJ's own communication has painted it into a corner. At its April meeting, three of the nine board members openly voted for an immediate rate hike—an unusual public disagreement that signaled growing internal pressure to tighten policy. This, combined with the Japanese government's intervention to support the weakening yen on the same day, has dramatically raised the stakes. If the BoJ fails to follow through with a hike in June, it could seriously damage its credibility in the market's eyes.
Second, Japan's economy is showing foundational signs of sustainable inflation. For the third consecutive year, the annual spring wage negotiations, known as 'Shuntō', resulted in strong pay increases of over 5%. Real wages have also started to grow, meaning people's purchasing power is increasing after adjusting for inflation. This is exactly the kind of wage-driven domestic demand the BoJ has been waiting for to justify normalizing its ultra-low interest rate policy.
While recent inflation numbers look soft, this is mostly due to temporary government subsidies on energy. The BoJ itself is forecasting inflation to rise to 2.6% by 2026. By hiking in June, the central bank would be acting proactively to get ahead of this expected rise, rather than waiting for the data to force its hand.
Citi's forecast doesn't just point to a single hike. It suggests a steady, predictable path of normalization with a 0.25% increase roughly every six months. This could take the policy rate from 0.75% toward 1.25–1.50% by late 2026. Even with these hikes, the 'real interest rate' (the policy rate minus inflation) would remain negative, meaning policy would still be supporting the economy, just less aggressively. This gradual approach aims to avoid shocking the financial system while firmly moving away from a zero-interest-rate environment.
- Shuntō: The annual spring wage negotiations between Japanese unions and companies, a key indicator of wage growth.
- Real Interest Rate: The interest rate adjusted for inflation. If the policy rate is 1% and inflation is 3%, the real rate is -2%.
- Hawkish: A term describing a monetary policy stance that favors higher interest rates to control inflation, as opposed to a 'dovish' stance that favors lower rates to stimulate growth.
