BOJ Raises Policy Rate to 31-Year High Amid Inflation Risks
By Drooid · · How we work
Core Event
On September 18 the Bank of Japan (BOJ) lifted its benchmark short-term policy rate by 25 basis points to 1.25 %, the highest level since 1995. The decision was approved by a 7-2 vote of the nine-member Policy Board. Board members Toichiro Asada and Ayano Sato voted against the hike, citing concerns that the economy remains fragile and core inflation is still below the 2 % target. The new rate takes effect on September 24.
Background & Context
The BOJ began normalising monetary policy in March 2024, ending decades of ultra-low and negative rates. Since then it has raised rates six times, most recently in June 2026, with a three-month interval—the shortest gap since 1990. The move comes as Japan faces rising import-price pressures from higher global oil prices and a weak yen that has amplified inflationary risks.
Data & Statistics
- Policy rate: 1.00 % -> 1.25 % (25 bp)
- Vote: 7-2 (Asada, Sato dissent)
- Headline CPI (August): 1.9 % YoY
- Core CPI (August): 1.7 % YoY, down from 1.8 % in July
- Wholesale inflation: corporate goods prices up 7.6 % YoY in August
- Yen/USD: slipped to 156.64-156.91 after the announcement
- 10-year JGB yield: fell 4.9 bp to 2.947 %
Official Statements & Responses
Governor Kazuo Ueda said the bank is entering a “new phase” focused on stabilising underlying inflation at the 2 % target rather than merely lifting it. He added that the BOJ will continue to adjust policy based on economic, price and financial-condition data, without committing to a fixed timetable for future hikes.
Criticism & Opposition
Board members Toichiro Asada and Ayano Sato, appointed by Prime Minister Sanae Takaichi, argued that core inflation remains below 2 % and that the economy does not yet warrant tighter policy. Their dissent was noted by analysts as a signal of internal division.
Conflicting Reports & Gaps
Sources differ on the exact post-hike yen level: CNBC reported 156.64, the Globe and Mail cited 156.91, and other outlets noted a range up to 157.84. All agree the yen weakened despite the rate increase.
Verbatim Quotes
- “It’s important to stabilize underlying inflation at 2 per cent. Our policy phase has changed,” — Kazuo Ueda

What’s Next
The BOJ’s next policy meeting is scheduled for October 29-30, where Governor Ueda will assess inflation trends and financial conditions. Analysts expect the bank could raise rates to 1.5 % by March 2027, with a possible terminal rate of 1.75 % or higher.
