The Bank of Japan (BOJ) increased its benchmark interest rate by a quarter point to 1.25% on Friday, September 18, 2026, concluding a two-day meeting. This move represents the fastest pace of rate hikes by the BOJ in 36 years, with the last comparable interval being March 1990. The decision was widely anticipated, with all economists surveyed by Bloomberg predicting the hike. The vote was 7-2, with board members Toichiro Asada and Ayano Sato dissenting from the majority decision.

This aggressive tightening comes as the BOJ confronts persistent inflation risks and significant external pressure, including "unusually explicit calls" for further policy normalization from Washington, specifically from US Treasury Secretary Scott Bessent. The rate hike aims to forestall the risk of inflation overshooting the BOJ's 2% target, which has become a growing concern for policymakers.

The 1.25% interest rate is now at a 31-year high. This marks the second hike in three months, signifying the shortest interval between increases since 1990. The Japanese yen has been trading at levels not seen since the 1980s, which, while beneficial for tourists, poses challenges for the broader economy.
