The International Monetary Fund (IMF) has endorsed the Bank of Japan's (BOJ) monetary policy normalization, suggesting that faster interest rate hikes may be necessary if inflation exceeds expectations.
Krishna Srinivasan, director of the IMF's Asia and Pacific Department, told Reuters that Japan's central bank is taking appropriate steps toward bringing interest rates to levels considered neutral for economic growth.
However, he warned that stronger-than-expected inflation could require more aggressive monetary tightening to prevent inflation expectations from becoming unanchored.
The comments come ahead of the BOJ's October policy meeting, where officials may maintain current interest rates while signaling another potential increase in December.
BOJ Governor Kazuo Ueda reiterated on Friday that the central bank remains committed to stabilizing underlying inflation around its 2% target. He emphasized that policymakers would not tolerate persistent inflation overshooting their objective.
Japan faces growing inflationary pressures from rising energy prices linked to the Middle East conflict, strong artificial intelligence-related demand, and a weaker Japanese yen.
The yen's depreciation has increased import costs, particularly for energy and raw materials, adding pressure on businesses and consumers.
These conditions prompted the BOJ to raise its benchmark interest rate to 1.25% in September, its highest level in 31 years, following an earlier increase in June. Analysts widely anticipate another rate hike before 2026 ends.
Meanwhile, the IMF highlighted the influence of speculative trading on yen movements. Its regional economic analysis found that currency fluctuations since mid-2025 were partly disconnected from traditional fundamentals, including interest rate differentials.
Despite Japan's coordinated currency intervention with the United States on July 31, Srinivasan maintained that Japanese authorities remain committed to a freely floating exchange rate.
Beyond monetary policy, the IMF urged Japan to establish a clearer medium-term fiscal framework to address investor concerns over government spending and public debt.
Markets remain cautious about the administration's proposed spending increases and a planned two-year consumption tax reduction beginning in April 2027.
Although Japan has achieved significant fiscal consolidation compared with other G7 economies since the pandemic, uncertainty surrounding the financing of new policies continues to raise concerns.
The IMF believes greater fiscal transparency, combined with carefully calibrated BOJ interest rate increases, would help strengthen investor confidence and support Japan's economic stability.
