Bank of Japan's Rate Hike Amid Iran War Inflation Concerns

The Bank of Japan (BOJ) is expected to raise its benchmark interest rate to 1.00% by the end of June 2026, as indicated by a recent Reuters poll where nearly two-thirds of economists foresee this adjustment. The potential for a hike in April or June is considered equally likely, driven by concerns over inflation stemming from the ongoing conflict in Iran. Since the outbreak of the U.S.-Israeli war with Iran on February 28, 2026, hawkish expectations have intensified, particularly regarding rising energy prices and the weakening yen. As of now, the yen has depreciated approximately 2% against the U.S. dollar since the conflict began.

The war in the Middle East is projected to impact Japan's core consumer price index (CPI), with 62% of economists predicting an increase of 0.2-0.4 percentage points over the next year. Despite these inflationary pressures, none of the economists surveyed expect the conflict to push Japan into recession. However, forecasts for annualized GDP growth have been revised downward, with expectations of 0.4% growth in the second quarter, down from 1.1%, and 0.7% in the third quarter, reduced from 1.2%.

The International Monetary Fund (IMF) has stated that the BOJ can "see through" inflation pressures linked to the Iran war, anticipating limited second-round effects on wages and core prices. Rahul Anand, the IMF mission chief for Japan, emphasized that while headline inflation may rise temporarily due to increased oil prices, it is unlikely to significantly affect broader price dynamics. The IMF projects that Japan's inflation will converge to the BOJ's 2% target by the end of 2027, allowing for a gradual increase in interest rates to approximately 1.5% by mid-to-late 2027.

Despite the optimistic outlook from the IMF, some economists express caution regarding the BOJ's decision-making amid heightened uncertainty from the Iran conflict. Junki Iwahashi, a senior economist at Sumitomo Mitsui Trust Bank, noted that while rising crude oil prices could temporarily elevate inflation, they may also negatively impact the economy, complicating the rate-hike decision.

The BOJ has been preparing for a near-term rate hike, citing persistent inflation above its target for the past four years. However, it remains cautious, as the evolving situation in the Middle East could unsettle markets and cloud economic forecasts. The BOJ's policy rate currently stands at 0.75%, significantly below the neutral rate that neither stimulates nor restricts economic activity.

As the BOJ approaches its April 27-28 policy meeting, the interplay between the Iran conflict and domestic economic conditions will be crucial in shaping its monetary policy. The central bank's ability to navigate these challenges while maintaining a gradual tightening path will be closely monitored by economists and market participants alike.
