The Nikkei 225 closed up 1.38% following the BOJ's rate hike to 1.25%, a move that pushed the yen past 157 against the dollar. Market participants view the two dissenting votes, both appointed under the Takaichi administration, as evidence of political reluctance toward further hikes, while tech stocks were further supported by pro-innovation statements from Nvidia leadership.

  • According to Mainichi Shimbun, the two dissenting votes against the hike were appointed under PM Takaichi's administration, which traders are reading as a signal of government resistance to aggressive tightening. This interpretation, combined with Nvidia CEO Jensen Huang's public pushback against AI restrictions, fueled the Nikkei's afternoon surge to over 2% before closing up 1.38%.
