Japan Raises Interest Rates to Highest Level in 31 Years

Japan’s Bank of Japan (BOJ) raised its policy interest rate from 1% to 1.25% on September 18, 2026, taking borrowing costs to their highest level in 31 years as the central bank responds to persistent inflation pressures. The decision marks another step away from Japan’s decades of ultra-low interest rates.

BOJ Raises Rate to 1.25%

The BOJ increased its short-term policy rate by 25 basis points, taking it to 1.25%, a level last seen in 1995.

The decision was approved by a 7–2 vote. Two board members, Toichiro Asada and Ayano Sato, opposed the increase.

The September move was the first rate increase in three months and continues the monetary-policy tightening cycle that began after Japan moved away from its decade-long stimulus framework in 2024.

Inflation Becomes the Central Concern

BOJ Governor Kazuo Ueda said the central bank's focus has shifted toward preventing inflation from exceeding its 2% target.

Underlying inflation has been approaching the BOJ's 2% objective, while higher energy costs and business-to-business price pressures have increasingly fed into consumer prices.

Japan's August core consumer inflation rate was 1.7% year-on-year, while the BOJ's preferred measure excluding fresh food and fuel stood at 1.9%.

More Rate Hikes Remain Possible

Ueda did not rule out further increases.

He said the BOJ could consider back-to-back rate hikes or a larger 50-basis-point increase if inflation risks intensify, although future decisions will depend on economic and price data.

The central bank has also indicated that financial conditions remain accommodative even after the latest increase.

Yen Weakens Despite Rate Increase

The interest-rate decision did not immediately strengthen Japan's currency.

The yen instead weakened against the U.S. dollar, with markets focusing on the two dissenting BOJ policymakers and uncertainty about the pace of future rate increases. The dollar briefly climbed to around 158 yen.

The currency's reaction highlights the importance of expectations around future monetary policy, rather than the current interest rate alone.

Japan Moves Further Away From Ultra-Low Rates

For decades, Japan maintained exceptionally low interest rates while struggling with weak inflation and periods of deflation.

The BOJ began dismantling that framework in 2024. The latest increase brings the policy rate closer to the bank's estimated 1.1%–2.5% neutral-rate range, according to Reuters.

Even at 1.25%, Japan's policy rate remains below the U.S. Federal Reserve's 3.75%–4% range and the European Central Bank's 2.5% rate.

What the Rate Hike Means

Higher interest rates can increase borrowing costs for households and businesses while making saving more attractive. For Japan, the BOJ is attempting to keep inflation stable without tightening financial conditions so sharply that economic activity is disrupted.

The rate decision also matters globally because the yen has historically been widely used as a low-cost funding currency. Changes in Japanese rates can therefore influence international borrowing, currency markets and investment flows.

The BOJ's next decisions will depend heavily on inflation, wages, energy prices, the yen and broader economic conditions.
