Ueda faces questions after two dissenters on BOJ rate hike to 1.25%

The Bank of Japan raised its policy rate by 25 basis points to 1.25%, the highest in 31 years, as anticipated by markets. However, the subsequent movement in the yen suggests the rate increase was not the key takeaway.

Attention has quickly turned to the 7-2 vote and the implications of the two dissenting opinions for future policy.

Toichiro Asada and Ayano Sato opposed the rate increase, giving the BOJ's stance on steady normalisation a more accommodative tone. That both were appointed recently by Prime Minister Sanae Takaichi has attracted scrutiny, especially because the government is wary of rising borrowing expenses.

This leaves BOJ Governor Kazuo Ueda in a difficult position before his press conference scheduled for 0630 GMT.

Asada and Sato have each articulated their views. The former maintains that further evidence of demand-led inflation backed by wage growth is needed, particularly as core inflation remains under 2%.

Sato's stance is more subtle. She has emphasised differentiating temporary cost-push inflation from sustained demand-led pressures, and contends the BOJ should weigh downside growth risks against upside inflation risks.

Nonetheless, the mere fact that Takaichi appointed both Asada and Sato earlier this year makes the division more conspicuous.

Regarding Ueda's upcoming remarks, the primary focus is on how he frames the dissents. Were they merely about timing, or do they reflect a more fundamental disagreement on the pace of rate increases?

The BOJ's overall statement retains a hawkish leaning. The central bank reiterates that it will hike rates further if its economic and inflation projections materialise. However, with the policy rate at 1.25%, it is already near the central bank's estimated neutral rate of 1.10% to 2.50%, making each subsequent increase more significant.

The burden is on Ueda to provide the details that the vote omitted.

If he dismisses the dissents as primarily about timing and maintains a hawkish outlook with further increases, the dovish reading of today's move might dissipate.

Conversely, if he stresses caution while aiming to preserve flexibility, the two opposing votes will appear more consequential.
