The Bank of Japan is poised to raise its policy interest rate to 1.25%, a 31-year high, as rising oil prices and import costs intensify inflation risks and strengthen the case for further monetary policy normalisation, Reuters reported.
The expected 25-basis-point increase would mark the first rate hike in three months and extend the central bank's gradual withdrawal from its long-standing ultra-loose monetary policy. Reuters reported that the decision comes as policymakers assess whether rising costs are becoming more persistent and could push inflation higher.

Higher energy prices have emerged as a key concern for the BOJ. Global oil prices have surged amid disruptions linked to the Middle East, increasing the cost of Japan's energy imports and adding to inflationary pressure. Japan's imports jumped 28% year-on-year in August, with higher oil prices contributing significantly to the increase, Reuters reported separately.
At the same time, domestic demand remains relatively resilient. Strong business investment and continued demand linked to artificial intelligence and semiconductor-related industries are adding to the broader economic backdrop that the BOJ is monitoring.
The rate increase would also bring Japan's policy rate closer to levels seen at other major central banks, although the BOJ's tightening cycle remains considerably more gradual after years of negative and near-zero interest rates.

Investors will closely watch BOJ Governor Kazuo Ueda's guidance after the meeting for clues about the pace of future rate increases. The policymakers may avoid providing firm guidance on the terminal rate, particularly given uncertainty over the outlook for inflation, energy prices and global economic conditions.
Markets are already assessing the possibility of additional rate hikes in 2027. Some economists expect the BOJ's policy rate to eventually reach at least 1.75%, although the pace and extent of further tightening remain uncertain.
The central bank also faces internal debate over the appropriate pace of policy normalisation. Board member Toichiro Asada has previously dissented on the timing of rate increases, highlighting differences within the BOJ over how aggressively it should respond to inflation risks.
Fiscal policy could further complicate the outlook. Expansionary government measures could provide additional support to domestic demand, while also increasing pressure on prices and government bond markets.
The BOJ therefore faces the challenge of containing inflation without triggering excessive volatility in Japanese government bonds or putting renewed downward pressure on the yen.
The yen has strengthened recently on expectations of a BOJ rate increase, while global currency markets are also being shaped by expectations for monetary policy decisions from the U.S. Federal Reserve and other major central banks.
Reuters reported that the BOJ's decision and Ueda's subsequent comments will be closely watched by investors for indications of whether Japan's tightening cycle is likely to accelerate as inflationary pressures persist.
