The Bank of Japan (BOJ) has raised its benchmark interest rate to its highest level in 31 years at Tokyo it happen on September 18, 2026 intensifying its efforts to contain inflation and prevent price pressures from becoming more deeply embedded in the Japanese economy.
The central bank increased its policy rate by 0.25 percentage points, from 1% to 1.25%, at the conclusion of its latest monetary policy meeting on Friday. The new rate is the highest since 1995 and represents another significant step away from the ultra-low interest-rate policies that defined Japan’s economy for decades.
The decision was approved by a 7-2 vote among the BOJ’s nine-member policy board. Two members opposed the increase, arguing that economic conditions did not yet provide sufficient justification for higher borrowing costs.
Inflation remains at the centre of the BOJ’s decision. Japan’s headline consumer inflation stood at 1.9% in August, while core inflation, which excludes fresh food prices, eased to 1.7% from 1.8% in July. A separate measure watched closely by the central bank, excluding both fresh food and fuel, increased by 1.9%, indicating that underlying price pressures remain close to the BOJ’s 2% target.
The central bank has become increasingly concerned that inflation could move above its target if higher energy costs, a weaker yen and stronger demand continue to push prices upward. Rising energy costs have added to concerns about imported inflation, while the weaker Japanese currency can make imported goods and raw materials more expensive for businesses and consumers.
The rate increase also marks another stage in Japan’s gradual departure from decades of exceptionally loose monetary policy. The BOJ ended its negative interest-rate policy in March 2024, beginning a process of policy normalisation after years of efforts to overcome deflation and weak price growth.
However, the latest decision does not necessarily indicate that the central bank will raise rates rapidly from here. Governor Kazuo Ueda has signalled that policymakers remain attentive to economic growth and financial-market stability. The two dissenting votes also highlighted differences within the board over how quickly monetary policy should be tightened.
Financial markets reacted cautiously to the announcement. Rather than strengthening, the yen weakened against the US dollar following the decision, reflecting uncertainty over the pace of future rate increases and the BOJ’s policy outlook.
For households and businesses, higher interest rates could gradually increase borrowing costs, including for loans and other forms of credit. At the same time, tighter monetary policy is intended to prevent persistent inflation from eroding purchasing power and becoming entrenched.
The BOJ’s latest move therefore places Japan at an important stage in its long transition from an era of near-zero interest rates toward a more conventional monetary-policy environment, with inflation, wages, currency movements and economic growth likely to remain closely watched in the months ahead.
