BoJ: Changing policy landscape with underlying CPI rising closer to 2% leading to 25-bps hike in December and, potentially, also in March
中文标题
日本央行：政策格局变化，潜在CPI升幅接近2%，导致12月加息25个基点，并可能在3月再次加息
Core conclusion · Tlines extraction
The Bank of Japan raised its policy rate by 25bp to 1.25% on 18 September, with two board members dissenting. Governor Ueda said the underlying CPI has moved closer to 2%, prompting a shortened three-month rate cycle. Natixis now expects 25bp hikes in December and March, lifting the rate to 1.75%, supported by an above-potential output gap and underlying CPI at 1.6% YoY in August.

Key arguments
- The BoJ shortened its rate cycle to three months from six after judging that underlying CPI has risen closer to 2%.
- Firms are more actively passing higher input costs and wages to customers, lifting medium-term inflation expectations and skewing inflation risks to the upside.
- The BoJ views the economic cycle as positive, expecting gradual growth from AI-related global demand and government policy, despite dissent over weak Q2-26 domestic demand.
- With the economy above potential, Natixis expects the policy rate at 1.75% after 25bp hikes in December and March.
Key numbers
- Policy rate after September hike
- 1.25%
- Projected policy rate after December and March hikes
- 1.75%
- Underlying CPI (excl. food and energy, August, YoY)
- +1.6%
- Output gap (Q2-26)

Main risks
- Board dissent over weak Q2-26 domestic demand could delay or derail further hikes.
- Inflation upswing may stall, especially if cost and wage pass-through proves temporary.
- Global AI demand may not sustain export momentum, undermining the BoJ's growth outlook.
Corresponding source evidence
While the decision was well expected, the market was caught by surprise that two board members, Asada and Sato, dissented from the hike, which slightly weakened the Yen.
As the medium-term inflation expectations have also increased, the BoJ assessed that the risk of inflation is on the upside.
