Bank of Japan Policy Board member Toichiro Asada warned that further interest rate hikes could have a greater impact on economic activity now that the policy rate has entered the estimated neutral range. Speaking at a meeting with local leaders in Nagasaki on November 12, Asada emphasized the need to carefully assess the effects of previous tightening before raising rates again. The BoJ estimates Japan’s neutral nominal interest rate at slightly above 1% to 2.5%, placing the current policy rate of 1.25% within that range. Although financial conditions remain accommodative, Asada argued that the scope for further tightening without affecting economic activity has narrowed. He warned that “policy interest rate hikes are now becoming more likely to have a larger impact on real economic activity than when the Bank began to raise the policy rate.”
Asada’s caution reflects concerns about the strength of domestic demand and the delayed effects of monetary tightening. He noted that bank lending rates and corporate borrowing costs have risen, while the full economic impact of a rate hike could take “one year or more” to become clear. Although labour market conditions remain tight, nominal wages are rising and real wages have shown positive annual growth since the beginning of 2026, he believes private consumption is broadly flat rather than a strong driver of economic expansion. Asada also warned that further tightening could weaken activity and ultimately lower underlying inflation. With the policy rate already within the estimated neutral range, he sees greater reason to evaluate the cumulative effects of earlier hikes before taking additional action.
On inflation, Asada acknowledged upside risks from energy prices, AI-related demand and Yen depreciation. He noted that underlying CPI inflation and medium- to long-term inflation expectations are broadly consistent with the BoJ’s 2% target, while consumer inflation excluding fresh food could accelerate clearly above 2% in the second half of fiscal 2026. However, he questioned whether recent price increases were sufficiently supported by domestic demand to justify faster tightening. “I believe that the recent price increases have not necessarily been driven by demand factors,” he said. The distinction is particularly relevant after October’s producer inflation accelerated from 6.8% to 7.1% yoy, exceeding expectations of 6.5%. While higher input and import costs could feed through to consumer prices, Asada emphasized that the extent of such pass-through remains uncertain. He therefore concluded that “it is necessary for the Bank to give due consideration to the pace of any policy rate hikes.”
The remarks reinforce Asada’s cautious position ahead of the BoJ’s December 17–18 policy meeting, when many analysts expect another 25bps increase from 1.25% to 1.50%. Asada opposed the June and September hikes, arguing that inflation and economic conditions did not yet warrant additional tightening. His latest speech does not explicitly indicate how he will vote in December, but his emphasis on the neutral rate range, weak consumption and the delayed impact of past hikes suggests continued reluctance to support rapid normalization. While the BoJ’s broader outlook acknowledges upside inflation risks and supports further adjustment of monetary accommodation when conditions warrant, Asada’s assessment highlights the opposing risk: raising rates too quickly could weaken demand before a sustainable wage-driven inflation cycle is firmly established.
Key Takeaways
- BoJ Policy Board member Toichiro Asada warned that further rate hikes could carry greater economic risks, as the current policy rate of 1.25% has already entered the estimated neutral range of slightly above 1% to 2.5%.
- Weak private consumption and delayed tightening effects support Asada’s cautious stance. He believes previous hikes may take a year or longer to fully affect economic activity, while recent inflation has not necessarily been driven by domestic demand.
- Asada acknowledged upside inflation risks but urged caution over the pace of tightening. His position contrasts with expectations for another 25bps BoJ hike in December, although he did not indicate how he intends to vote.
