BOJ may need to tighten faster if inflation beats forecast, IMF says

The Bank of Japan (BOJ) is normalizing monetary policy and may need to raise interest rates faster if inflation exceeds forecasts, according to a senior International Monetary Fund (IMF) official. Japan must also provide a clear plan for funding its significant spending initiatives and present a medium-term fiscal framework to alleviate concerns about fiscal risks, said Krishna Srinivasan, director of the IMF's Asia and Pacific Department.

The IMF official expressed confidence in Japan's commitment to a freely floating exchange rate, emphasizing that they have not doubted this stance. Inflation is driven by factors such as the Middle East conflict and high demand for artificial intelligence (AI), and policymakers are discussing these issues during the IMF's annual meetings in Bangkok.

The BOJ Governor, Kazuo Ueda, reiterated the central bank's goal to keep underlying inflation near its 2% target and avoid any overshoot, reaffirming its resolve to continue raising interest rates. The yen's weak value contributes to inflation by increasing the cost of import raw materials. Japan conducted a joint intervention with the US on July 31 to prevent the currency from weakening further, potentially destabilizing financial markets.

The IMF staff analysis revealed that most yen movements since mid-2025 were speculative rather than fundamental. A significant portion of recent yen fluctuations is attributed to speculative positions in yen futures. Srinivasan confirmed that Japan has a robust foreign exchange market, allowing the exchange rate to move as a first defense.

Overall, Japan has demonstrated fiscal consolidation more than any other G7 country since the pandemic, driven by rising tax revenues. However, markets are concerned about the fiscal risks due to uncertainty surrounding how Japan will finance the administration's spending plans and a two-year reduction in the consumption tax.
