BOJ Expected to Raise Rates to 1.25% in September Policy Meeting

The Bank of Japan is widely expected to implement a 25 basis point interest rate hike at its September 17-18 meeting, lifting the policy rate to 1.25% to reach levels unseen in 31 years. According to a Reuters report, officials are likely to offer few concrete clues regarding the ultimate peak of the rate-hike cycle as board members remain divided on how far borrowing costs should rise.

"With underlying inflation so close to 2%, the BOJ needs to be extra mindful of upside price risks," said one of four sources familiar with the central bank's thinking.

Inflation Pressures and Economic Projections

The anticipated policy shift comes as broader price pressures persist across the Japanese economy. Annual wholesale inflation reached 7.6% in August, underscoring the ongoing pass-through of import costs and wages.

Quarterly projections released by the central bank in July indicate that core consumer inflation is expected to reach 2.5% for the fiscal year ending March 2027. The forecast anticipates inflation will ease slightly to 2.4% the following fiscal year before moderating toward the bank's 2.0% target.

Divergent Board Views on the Terminal Rate

While markets anticipate tighter policy, central bank officials have expressed varying assessments of price momentum. Board deliberations highlight differing views on whether inflation will settle stably at target levels or require more aggressive tightening.

"Underlying inflation is about to reach 2%, but we don't see it sharply overshooting that level," BOJ board member Kazuyuki Masu said on Thursday.

Analyst Forecasts and Market Expectations

Beyond the upcoming September meeting, economists surveyed by Reuters project further gradual normalization of Japanese monetary policy. Analysts anticipate the policy rate will advance to 1.5% by the end of March next year, followed by an additional increase to 1.75% during the second quarter of 2027. Most surveyed forecasters view 1.75% as the baseline terminal rate for the current tightening cycle, though policymakers have refrained from formalizing a specific ceiling.
