The Bank of Japan raised its benchmark interest rate to a 31-year high of 1.25% on September 18, 2026, to combat inflation fueled by high energy prices and a weak yen. The 7-2 majority decision aligns with global tightening by the Federal Reserve and European Central Bank. Despite the hike, the yen weakened past 157 per dollar.
