Japan raises interest rate to new 31-year high to curb rising prices
Japan's central bank increased its main interest rate to 1.25%, a 31-year high, continuing its shift from ultra-low borrowing costs amid rising prices and a weak yen. This move aims to curb inflation and align with global central bank tightening efforts.

The Bank of Japan (BOJ) has raised its key interest rate to 1.25%, the highest since 1995, marking its sixth hike since 2024. This widely anticipated decision reflects the BOJ's efforts to combat rising inflation, a persistently weak yen, and global economic pressures, including higher energy prices exacerbated by the Iran war.
Imagine your piggy bank usually gives you almost no extra money for saving. Now, the Bank of Japan, like the grown-ups' piggy bank, is giving a bit more extra money (interest) for saving. They're doing this because things like food and gas are getting more expensive, and they want to make sure your parents' money buys enough. It also makes Japan's money look stronger to other countries.
Analysis
1.25%
The Bank of Japan's decision to raise its main interest rate to 1.25% marks a significant departure from its long-standing ultra-loose monetary policy. This new rate is the highest seen since 1995, underscoring the central bank's commitment to normalizing its financial stance after years of negative or near-zero borrowing costs. The hike is the sixth such increase since 2024, when the rate stood at minus 0.1%, indicating a sustained effort to bring Japan's monetary policy in line with other major economies.
Historically, a central bank raising interest rates, a process known as tightening monetary policy, tends to strengthen the country's currency. This occurs because higher rates make the currency more attractive to international traders and investors seeking better returns on their investments. For Japan, a stronger yen could help mitigate the impact of rising import costs, particularly for essential goods like energy.
Iran war
A significant factor contributing to Japan's current inflationary pressures is the global surge in energy prices, directly linked to the Iran war. The conflict has caused major disruptions to shipments through the critical Strait of Hormuz, a vital chokepoint for global oil and gas supplies. Japan is particularly vulnerable to these supply interruptions due to its heavy reliance on energy imports from the Middle East, making it highly susceptible to price volatility in the region.
While Japan's core inflation rate, which eased slightly to 1.7% in August, remains modest by international standards, the very presence of rising prices is a relatively new phenomenon for the country. For approximately three decades prior, Japan had grappled with persistent low inflation or even deflation, meaning falling prices. The current inflationary trend, therefore, represents a notable shift in its economic landscape, driven in part by external geopolitical events.
Scott Bessent
The pressure on the Bank of Japan to tighten its monetary policy has also come from international quarters, notably from US Treasury Secretary Scott Bessent. Bessent has publicly urged BOJ Governor Kazuo Ueda to "do the right thing" and raise interest rates to support the yen, which has been under significant pressure. In August, Tokyo and Washington undertook a coordinated intervention to halt a slide in the yen after it reached a 40-year low, marking the first such joint action since 2011.
This coordinated effort, coupled with Bessent's direct calls, highlights the international concern over the yen's weakness and its potential implications for global financial stability. Market analyst Lale Akoner from eToro noted that if the yen remains weak despite higher rates, the resulting inflation pressure could compel the BOJ to tighten monetary policy even faster than markets or the Japanese government might prefer, potentially leading to further economic adjustments.
Key points
- Bank of Japan raised its main interest rate to 1.25%, a 31-year high.
- This is the sixth rate hike since 2024, moving away from ultra-low borrowing costs.
- The move aims to curb rising prices, which are partly driven by higher energy costs due to the Iran war.
- Japan faces economic challenges including a weak yen, rising prices, and a shrinking workforce.
- Core inflation eased slightly to 1.7% in August but remains near the 2% target.
- Tokyo and Washington jointly intervened in August to support the yen after it hit a 40-year low.
The rate hike could successfully curb rising prices, bringing inflation closer to the BOJ's 2% target without stifling economic growth. A stronger yen, supported by higher rates and potential future interventions, could also alleviate import cost pressures for Japan.
Despite the rate hikes, the yen could remain weak, leading to persistent inflation pressure and potentially forcing the BOJ to tighten monetary policy more aggressively than desired. This could risk slowing down Japan's economy, which has only recently emerged from decades of deflationary pressures.
