BOJ Rate Hike and Market Reaction
The Bank of Japan (BOJ) unanimously decided to increase the policy rate by 25 basis points to 0.75%. This move was anticipated, and the BOJ emphasised its intent to continue tightening monetary policy due to low real interest rates.
The USD/JPY exchange rate rose by over 1% to approximately 157.40. This was influenced by the BOJ’s decision to maintain a broad estimate of the neutral rate, remaining between 1% and 2.5%.
The BOJ hinted at persistent wage and inflation pressures, suggesting a potential for further rate hikes. BOJ Governor Ueda noted that the policy rate is still below the lower end of the neutral rate range.
Market expectations indicate a possibility of 75 basis points of BOJ rate hikes in the next two years. Simultaneously, the Fed may ease by 50 basis points, which could cause the USD/JPY to align with two-year implied policy rate differentials, potentially trading closer to 140.00.
The Bank of Japan raised its policy rate to 0.75% today, but the market viewed this as a dovish move. This pushed the USD/JPY pair up over 1% to near 157.40. The reason for this reaction was the central bank’s refusal to tighten its wide estimate for the neutral interest rate.
We believe traders should fade this narrative that the BOJ will remain accommodative for long. Governor Ueda himself noted that the current policy rate is still well below the low end of their neutral rate estimate of 1.0%. This signals a clear intention to continue hiking rates in the coming months.
Japan’s Economic Indicators and USD/JPY Outlook
This view is supported by Japan’s persistent inflation, with the nationwide core CPI for November 2025 coming in at 2.7%, marking the 20th consecutive month above the BOJ’s 2% target. The central bank also warned that wage-setting behavior remains strong, meaning inflation is unlikely to cool on its own. These conditions create a low bar for further rate hikes in early 2026.
In contrast, the US economy is showing signs of slowing, making Fed rate cuts more likely in the new year. The most recent jobs report for November 2025 showed a notable slowdown in hiring, and US core inflation has steadily cooled to 2.5%. This policy divergence between a hiking BOJ and a cutting Fed is the central reason for our outlook.
Derivative traders should consider positioning for a significant drop in USD/JPY. The recent spike to 157.40 has increased implied volatility, making options pricier, but put options or put spreads could offer a way to profit from a move down. We are seeing a similar dynamic to what occurred in late 2023, when the market began to price in the end of the Fed’s hiking cycle against a backdrop of a potentially shifting BOJ.
The swaps market is currently pricing in 75 basis points of BOJ hikes over the next two years, while simultaneously pricing in 50 basis points of Fed cuts. This fundamental gap between the two countries’ expected interest rate paths is not reflected in the current exchange rate. This suggests the USD/JPY pair has significant room to fall, converging towards our target of 140.00.
