BOJ Board Member Sato Supports Gradual Rate Hikes, Says Inflation Risks Tilted to the Upside
nashnova research
Ayano Sato, widely seen as the BOJ board's most dovish voice, publicly endorsed gradual rate increases and called inflation risks "slightly tilted to the upside" — internal consensus on hikes is firmer than markets assumed, raising the odds of a December move.
Why is a dove suddenly backing rate hikes?
Sato joined the BOJ's nine-member board in June, nominated by PM Sanae Takaichi, and was widely tagged as the board's dovish member.
In September she voted against a hike, citing weak consumption momentum and no acceleration in core inflation.
Yet in a new Kyodo interview she stated clearly: "Financial conditions remain accommodative — I support gradual rate adjustment."
This means → even the most cautious voice on the board agrees rates should keep rising. The debate is only about pace, not direction.
How does she read inflation?
Sato noted the Middle East conflict is pushing oil prices higher, tilting the inflation outlook "slightly to the upside."
In a separate Asahi Shimbun interview she added: core inflation is approaching the BOJ's 2% target.
In plain terms = the probability of prices running hotter than forecast now exceeds the probability of undershooting — exactly the condition that justifies tightening.
How far is she from the board mainstream?
Sato herself said her monetary-policy stance has "no major difference from the majority of the board."
She added that rate hikes support sustainable growth, and that while the BOJ sets policy independently, its direction will "ultimately align with the government's proactive fiscal policy."
This reflects a dove actively closing the gap with the mainstream — publicly endorsing the hike trajectory adds an extra layer of insurance to the board's consensus.
What happens in October and December?
Reuters, citing sources: the BOJ will likely stand pat in October but is expected to send hawkish signals, paving the way for a December hike.
Context: the BOJ already raised rates in June and September, lifting the benchmark to a 31-year high of 1.25%; Governor Kazuo Ueda said the bank has entered a phase of "preventing inflation overshoot."
This means → a dovish member openly backing the hike direction signals that internal resistance to a December move is weaker than markets had assumed — a key precondition for that hike to land.
