Bank of Japan Raises Interest Rate to 1.25% as Inflation Risks Persist
Tokyo, September 18, 2026: The Bank of Japan has raised its benchmark interest rate to 1.25%, taking borrowing costs to their highest level in 31 years as policymakers respond to continuing inflationary pressures and rising energy costs.
The decision was taken at the central bank’s two-day monetary policy meeting that concluded on Friday. The increase from 1% was approved by a 7-2 vote, with board members Toichiro Asada and Ayano Sato voting against the move.
BOJ Moves Further Away From Ultra-Low Rates
The latest increase marks another step in Japan’s gradual shift away from the ultra-loose monetary policy that had characterised its economy for decades.
The central bank has been raising rates as it assesses whether inflation can remain sustainably around its 2% target. BOJ Governor Kazuo Ueda has indicated that future policy decisions will depend heavily on economic and price data.
The latest decision also brings the Japanese policy rate closer to the central bank’s estimated range for a neutral interest rate.
Energy Costs Add to Inflation Concerns
Rising energy prices have become an additional concern for Japanese policymakers. Higher oil costs can increase wholesale prices and eventually feed through into consumer prices.
The BOJ has also been watching the impact of a weaker yen on import costs. Japan relies heavily on imported energy and other commodities, making currency movements an important factor in the country’s inflation outlook.
Ueda said the central bank must remain alert to the possibility that renewed increases in energy prices could create additional inflationary pressure.
Yen Does Not Immediately Strengthen
Despite the rate increase, the Japanese yen initially weakened against the U.S. dollar.
Market participants focused partly on the two dissenting votes and the absence of a clearly defined timetable for further increases. The currency reaction showed that investors were looking not only at the size of the rate hike but also at the BOJ’s guidance regarding its next steps.
Future Rate Decisions Remain Data-Dependent
Governor Ueda said the BOJ has not established a fixed schedule for future rate increases.
According to his comments, the central bank will examine economic conditions and inflation developments at each policy meeting before deciding how quickly borrowing costs should rise. He also cautioned that financial conditions should not tighten so rapidly that they create excessive pressure on economic activity or asset prices.
Japan Joins Broader Global Tightening Cycle
The BOJ’s latest move comes as other major central banks are also dealing with inflation risks and changing economic conditions.
For Japan, however, the increase represents a significant development after years of exceptionally low interest rates. The central bank is now attempting to balance two objectives: preventing inflation from moving persistently above its target while avoiding an excessive tightening of financial conditions.
The next stage of Japan’s monetary policy will therefore depend on incoming inflation, wage, energy and economic data rather than a predetermined sequence of rate increases.
