The Bank of Japan raised its policy interest rate by 25 basis points to 1.25% on 18 September 2026, the highest level since 1995 and the fastest pace of rate increases in over three decades. The decision, passed by a 7-2 vote, was driven by rising inflation and follows a broader tightening cycle by major central banks including the US Federal Reserve and European Central Bank. Governor Kazuo Ueda declined to signal a further rate increase at the next meeting, emphasising data dependency in his forward guidance.
Following the decision, the yen weakened against the US dollar, with USDJPY surging toward 158.00 according to Finnhub, and the yen declining 0.72% as reported by Guardian Business. The Nikkei 225 gained 1.5% as the weaker yen supported Japanese export-oriented equities, while the 10-year Japanese Government Bond yield declined after the announcement.
The Japanese yen (USDJPY) moved directly in response to the rate decision and Ueda's guidance, weakening despite the rate increase as markets interpreted the cautious commentary as a signal of a slower tightening pace. Japanese Government Bonds (JGBs) saw their 10-year yield fall post-announcement, and the Nikkei 225 rose as a weaker yen reduced the cost competitiveness burden on major Japanese exporters.
The two dissenting votes within the BOJ's policy board were noted by Guardian Business as reflecting internal division over the pace of tightening, with some members signalling preference for a pause. Bloomberg Markets separately reported that retail demand for Japanese government bonds has reached record levels amid the rising yield environment, adding context to the domestic fixed-income landscape surrounding the decision.
