Bank of Japan Policy Board member Ayano Sato sounded notably less dovish than her September dissent suggested, saying in an interview with Kyodo News in Tokyo on October 5 that she supports continued gradual tightening. Sato, one of two board members who opposed last month’s hike to 1.25%, said, “I support the policy of adjusting (the key rate) gradually,” adding that higher rates “can contribute to achieving sustainable economic growth.” Her remarks suggest that September’s disagreement was more about the timing of the move than opposition to further normalization itself.
That distinction carries added political significance because Sato joined the BOJ board in June after being appointed by the government of Prime Minister Sanae Takaichi, who has expressed caution over higher interest rates. Sato stressed that the BOJ should make policy decisions independently while ultimately aligning monetary policy with the government’s broader expansionary fiscal stance. Explaining her September dissent, she said private consumption momentum “has not been that strong”, and argued that future rate decisions should take account of trends in household spending and income. The message is therefore not resistance to higher rates, but a preference for a slower pace until domestic demand looks more durable.
Sato also described a more two-sided risk environment. She acknowledged that inflation risks have increased somewhat because of Middle East instability and higher crude oil prices, but warned that strong AI-related demand could weaken abruptly, causing the outlook to “shift sharply toward pessimism.” A worsening Middle East conflict could likewise cool the economy and eventually slow inflation. For markets, the key takeaway is that even a newly appointed member associated with the BOJ’s dovish flank is not rejecting further hikes. The debate increasingly looks centered on how quickly the BOJ should tighten, rather than whether normalization should continue.
Key Takeaways
- Sato’s September dissent was about timing, not direction. She still supports gradually raising the policy rate.
- She said higher rates “can contribute to achieving sustainable economic growth,” making her stance less dovish than the dissent alone suggested.
- The signal carries added weight because Sato was appointed under Prime Minister Sanae Takaichi, whose government has taken a more cautious stance toward higher interest rates.
- Sato nevertheless stressed BOJ policy independence, while saying monetary policy should ultimately coexist with the government’s expansionary fiscal stance.
- Her main concern remains weak private consumption, which she said “has not been that strong.”
- Future hikes should therefore depend on consumption and income trends, rather than following a predetermined schedule.
- Sato acknowledged greater upside inflation risks from Middle East instability and higher crude oil prices.
- But she also highlighted downside risks, warning that AI-related demand could weaken sharply and the outlook could “shift sharply toward pessimism.”
- The broader implication is that the BOJ debate may increasingly be about how quickly to normalize, rather than whether normalization should continue at all.
