BOJ Minutes Confirm Hawkish Board Member's Prescience on Rate Hike

The Bank of Japan's July minutes are set to be released, but they may already feel like old news given how quickly events have overtaken them. At the time, the board voted 8-1 to hold the overnight call rate near 1.0%, with board member Hajime Takata as the lone dissenter, proposing an immediate move to 1.25%. Takata argued that Japan had entered a new phase requiring a more nimble policy response to upside inflation risks and shifting overseas financial conditions.

The accompanying summary of opinions described inflation risks as significantly skewed to the upside, citing yen weakness, geopolitical tensions, elevated crude oil costs, and AI-driven demand, with one unnamed board member warning that the pace of future hikes could end up faster than markets were pricing.

That warning was borne out within two months. At its 17-18 September meeting, the BOJ raised its policy rate to 1.25%, the highest level since 1995, effectively delivering the exact outcome Takata had called for in July. The vote this time was 7-2, with members Toichiro Asada and Ayano Sato dissenting in favour of holding steady.

Despite the actual rate hike, the yen weakened further, with USD/JPY pushing past the 157 level. This can be attributed to the divided 7-2 vote signalled genuine disagreement within the board over the pace of further tightening and Governor Kazuo Ueda's press conference offering none of the hawkish forward guidance that would have been needed to convince markets a faster hiking cycle was coming.

With US interest rates still substantially higher than Japan's even after the move to 1.25%, the yen carry trade remains largely intact. Ten-year Japanese government bond yields fell on the dovish framing, while the Nikkei 225 rallied 1.5% as equity investors welcomed signs the BOJ would not tighten aggressively from current levels.

Core inflation data added to that more benign read, easing to 1.7% in August from 1.8% in July. Today's minutes, in that context, function less as a forward-looking signal and more as confirmation of how close the July board came to moving early, and how right its most hawkish member turned out to be.
