The Bank of Japan raised its benchmark policy rate by 25 basis points to 1.25% on September 18, 2026, marking the highest level in about 31 years and the sixth rate hike since ending ultra-loose monetary policy in 2024. The move, confirming what markets had priced at 97% the day before, reflected persistent inflation approaching the BOJ's 2% target, driven by higher oil prices and a weaker yen.
