BOJ Shifts Policy Toward Preventing Inflation Overshoot
By Drooid · · How we work
Core Event
At its September 17-18 meeting, the Bank of Japan raised its policy rate to 1.25 %, the highest level in roughly 31 years. The board signaled a “new phase” focused on averting an inflation overshoot rather than merely nudging underlying inflation toward the 2 % target. Minutes released on October 1 show several members urging faster or larger hikes to keep inflation in check.
Background & Context
Since 2013 the BOJ has pursued ultra-easy monetary policy, aiming to lift price growth gradually to 2 %. After modest hikes in 2024-25, the central bank pivoted in June 2025, raising rates to 1.0 % as import-price pressures rose. The September increase continued that shift, reflecting concerns that a weak yen and higher oil prices could push inflation above target.
Data & Statistics
- Policy rate: 1.25 % (September).
- Tokyo core consumer inflation: 2.4 % in September, up from 1.8 % in August.
- Nationwide core-inflation forecast: 2.5 % for fiscal 2026 and 2.4 % for fiscal 2027.
- Core-inflation gauge (ex-fresh food): 2.6 % in August, up from 2.3 % in July.
- Market expectations: overnight-swap pricing assigns a 30 % probability of a rate hike at the October 30 decision.
- Terminal-rate projections: former executive director Kazuo Momma expects a rate around 2 % by mid-2027; a Bloomberg survey places the median terminal rate at 1.75 %.
Official Statements & Responses
Governor Kazuo Ueda said the BOJ has entered a phase aimed at “forestalling inflation risks,” noting rising long-term inflation expectations and steady wage gains as signals that underlying inflation is nearing 2 %. Former board member Makoto Sakurai projected the policy rate could reach 2 % by around June 2027.
Criticism & Opposition
Board members Toichiro Asada and Ayano Sato dissented from the September hike, warning that weak consumption and subdued services-inflation could justify a pause. A Cabinet Office representative echoed these concerns, emphasizing the need to balance price stability with growth.
Conflicting Reports & Gaps
- Timing of the next hike: Reuters cites possible moves in October or December, while Bloomberg’s poll shows a majority favoring a January decision.
- Terminal rate outlook: Momma’s interview suggests a 2 % terminal rate by mid-2027, whereas Bloomberg’s median estimate is 1.75 %. The BOJ has not disclosed a definitive target.
- Inflation trajectory: Some analysts point to accelerating core inflation (2.4 % in Tokyo, 2.6 % core gauge), while BOJ officials note “no clear evidence” of an imminent sharp spike.
Verbatim Quotes
- “The key would be how much the BOJ will revise up its fiscal 2027 inflation forecasts ... and how far it could push back the timing for when inflation peaks,” — Mari Iwashita, executive rates strategist at Nomura Securities
- “The basic pace will probably be once every three months, but there’s also a reasonable chance that the BOJ could raise rates at consecutive meetings,” — Kazuo Momma, ex-official
What’s Next
Traders are pricing a roughly 30 % chance that the BOJ will raise rates at its October 30 meeting. Market participants will watch the upcoming “Tankan” business-confidence survey and Friday’s inflation data for signals of rising corporate-inflation expectations. If underlying inflation continues to approach 2 %, the BOJ may consider additional hikes before year-end, with a possible terminal rate near 2 % by mid-2027.
