Bank of Japan Raises Interest Rate to 31-Year High to Address Economic Pressures

The Bank of Japan has raised its main interest rate to a new 31-year high as it moves away from decades of ultra-low borrowing costs amid increasing economic pressures. On September 18, 2026, the Bank of Japan (BOJ) increased the rate from 1% to 1.25%, a level not seen since 1995. This decision aligns with a trend among major central banks globally, as they also raise rates in response to rising inflation driven by higher energy prices related to the Iran war. The BOJ has been incrementally raising the rate since 2024, when it was at minus 0.1%, marking six rate hikes in the last two and a half years. Typically, when a central bank raises rates, the country's currency strengthens as it becomes more appealing to traders. Japan is currently facing multiple economic challenges, including a weak yen, rising prices, and a shrinking workforce. Official figures released ahead of the BOJ's announcement indicated that inflation eased slightly last month, with core inflation falling to 1.7% in August from 1.8% in July, though it remains close to the bank's 2% target. Japan's inflation rate, while not high by international standards, represents a significant shift for an economy that had experienced low inflation or deflation for approximately three decades. Global oil and gas prices have surged this year due to disruptions caused by the Iran war, which has particularly impacted Japan, given its reliance on energy imports from the Middle East. In August, Japan and the United States confirmed a joint intervention to stabilize the yen after it reached a 40-year low. This coordinated effort was the first since 2011, and both Japan's Ministry of Finance and US Treasury Secretary Scott Bessent indicated they would not hesitate to conduct further joint interventions if necessary. Bessent has also urged BOJ Governor Kazuo Ueda to raise interest rates to support the yen.
