Core conclusion · Tlines extraction
BOJ hiked rates 25bp to 1.25% on a 7-2 vote, but markets read the meeting as dovish: no faster hike signal, two PM-aligned dissenters favouring a hold, no 50bp hike from Takata or Tamura, and Governor Ueda seeing low probability of back-to-back hikes. USD/JPY rose from 156 to above 158, then fell below 157 on reported BOJ rate-check news ahead of a 3-day holiday.

Key arguments
- BOJ hiked 25bp to 1.25% on a 7-2 vote, with Asada and Sato dissenting for a hold.
- Markets read the meeting as dovish: unchanged economic description, no 50bp hike from Takata or Tamura, and Ueda assigning low probability to back-to-back hikes.
- News reports of a BOJ rate check during the New York session pushed USD/JPY from 158 to below 157, with intervention risk in focus ahead of a 3-day holiday.
- Focus later in the week turns to the 24 September Trump-Xi summit, with signs of possible US-China AI dialogue.

Main risks
- Further intervention risk if USD/JPY moves sharply higher, with a 3-day holiday thinning liquidity.

- Trump-Xi summit outcome remains uncertain, with expectations generally low despite positive initial signs.
Corresponding source evidence
Second, the vote for the decision was 7-2 including two dissents with board members Toichiro Asada and Ayano Sato – Prime Minister Sanae Takaichi ’s administration ’s BOJ board appointees - dissenting in favour of a hold.
Third, while there was some speculation that more hawkish members of the board such as Takata and Tamura might vote for a larger 50bps hike, this was not the case although both did dissent against the description of inflation in the statement.
