Editor's Note: The Bank of Japan's June rate hike expectations continue to rise. The market currently anticipates a high probability that it will raise the short-term policy rate from 0.75% to 1%; if implemented, Japan's borrowing costs will reach their highest level since 1995.

The core factor driving this increased rate hike expectation is inflationary pressure caused by rising energy prices. Tensions in the Middle East have pushed up global oil and gas costs, and Japan, which is highly dependent on energy imports, faces the risk of corporate costs continuing to pass through to consumer prices.

This also places the Bank of Japan in a delicate position. On one hand, wholesale inflation is rising, and hawkish statements from central bank officials indicate growing concern that inflation will remain above the 2% target for the long term; on the other hand, further escalation of Middle Eastern conflicts could trigger market turmoil and weigh on economic growth.

For the Bank of Japan, the June rate hike is not only a response to inflationary pressures but also an important step in normalizing monetary policy after a long period of easing. The real variables moving forward will be whether energy shocks can be contained and whether geopolitical risks will ultimately alter the central bank’s judgment at the last minute. In other words, whether the BOJ can raise rates to 1% in June will depend on three factors: inflation trends, energy prices, and the situation in the Middle East.

Key Takeaways

· The Bank of Japan is expected to raise rates to 1% in June.

· Rising energy costs are intensifying Japan’s inflation concerns.

· Escalation of Middle Eastern tensions could disrupt this rate hike plan.

· If the Middle Eastern conflict does not sharply escalate, the BOJ is expected to raise the benchmark rate to 1% at the policy meeting on June 15-16. As energy costs push up inflation, the case for tightening monetary policy is becoming stronger.

BOJ Signals a Rate Hike in June

According to market estimates, investors currently assign about an 80% probability that the BOJ will raise the short-term policy rate from 0.75% to 1%. If approved, Japan’s borrowing costs will reach their highest level since 1995.

This rising expectation stems from a series of hawkish signals recently issued by BOJ officials. Among them, BOJ Governor Ueda Kazuo stated on Wednesday that the central bank is shifting its policy focus toward curbing inflation. Analysts interpret this as a strong indication that policymakers are preparing to push for a new round of rate hikes.

An insider familiar with BOJ thinking said, “Unless there is a serious escalation in the conflict, the BOJ is very likely to raise rates in June.”

Two other insiders also expressed similar views, noting that although geopolitical uncertainties are increasing, current economic conditions still support further rate hikes.

Energy Shock Worsens Inflation Concerns

A new round of conflict in Iran has driven up global energy prices, adding pressure on Japan, an economy heavily reliant on imports. Policymakers worry that rising fuel costs could lead companies to pass higher costs onto consumers, further fueling inflation.

Recent data shows wholesale inflation in Japan has surged significantly, heightening these concerns. BOJ officials fear that if cost increases persist, consumer inflation could remain above the 2% target for longer than previously expected, reinforcing market expectations for a rate hike by June 2026.

BOJ policy board members Watanabe Kazuhiro and Koeda Junko have recently warned that price pressures are rising, signaling support for tightening monetary policy. Their statements indicate an internal consensus is forming: inflation risks now outweigh concerns about economic slowdown.

Since ending a decade-long easing policy in 2024, the BOJ has raised rates multiple times. Officials believe that after years of weak price growth, Japan is now closer to achieving a stable, long-term inflation target.

Middle Eastern Conflict Remains a Key Risk

Although market expectations for a June 2026 rate hike are rising, policymakers remain closely monitoring developments in the Middle East before making a final decision.

Sources say BOJ officials will continue to assess market conditions and the impact of the conflict until the last moment. If the situation escalates significantly, causing market turmoil or threatening economic stability, the plan may change.

This conflict presents a dilemma for policymakers: rising energy prices could push inflation higher, but could also dampen economic activity. Japan remains highly dependent on imported fuel, making it especially vulnerable to shocks in the global energy markets.

The bond market has already responded to inflation concerns. As investors increase bets on further tightening by the BOJ, Japanese government bond yields rose to nearly a 30-year high last month.

However, current evidence still points toward the BOJ raising rates again. This reflects growing confidence among policymakers that inflationary pressures are becoming more entrenched and require a stronger policy response.
