BOJ set to raise rates to 31-year high at September meeting

The Bank of Japan is set to raise its benchmark interest rate by 25 basis points to 1.25% at its September 17-18 meeting, according to a report by Kyodo News, in what would be the highest policy rate in roughly 31 years. The move would mark the latest step in Japan's historic exit from decades of ultra-loose monetary policy, but falls short of the jumbo 50-basis-point increase some had speculated about in recent weeks.sedaily

A Gradual Path Forward

According to Reuters Thomson Reuters Corporation ↘ 6.56%, people familiar with the BOJ's thinking see little appetite within the central bank for a 50-basis-point increase this month. Policymakers remain wary that such a move could unsettle households and businesses still adjusting after decades of near-zero borrowing costs. A Reuters poll published in late August found that a majority of economists expected the BOJ to raise rates in September, though the consensus centered on a standard 25-basis-point increment.economictimes+1

Markets have largely priced in the smaller hike. Prediction markets showed an 86-cent probability on a 25-basis-point increase as of late August, while Takuji Aida, an economic adviser to Prime Minister Sanae Takaichi, told media he expects the BOJ to hike in September and again by January, maintaining roughly quarterly increases.indexbox+1

The BOJ raised rates to 1% in June in a 7-1 vote, continuing a tightening cycle that began in March 2024 when the bank ended eight years of negative interest rates.policyrix

Inflation Pressures Versus Yen Strength

The case for continued tightening rests on persistent inflation driven by rising oil prices, a weak yen, and elevated import costs. Bank lending rose 5.4% year-on-year in August, suggesting financial conditions remain relatively accommodative despite cumulative rate increases.economictimes+1

At the same time, the yen's recent appreciation to around 153 per dollar — its strongest level in seven months — has eased some urgency for aggressive action, according to Reuters. A stronger yen reduces imported inflation by lowering the domestic cost of foreign goods and commodities.economictimes

Broader Market Implications

Japan's monetary normalization is reverberating through global bond markets. As the Japan Times noted, after a quarter century battling deflation, the BOJ has been raising rates and reducing its purchases of sovereign bonds, pushing Japan's 10-year note yields to their highest in around 30 years. But those yields are "what you would expect in an economy with moderate inflation and positive real economic growth," the commentary argued.japantimes

The BOJ's nine-member policy board remains divided on the pace of tightening. Board member Toichiro Asada opposed the June rate increase, arguing policymakers should wait for clearer evidence of demand-driven inflation, while Governor Kazuo Ueda has stressed the need to assess the cumulative impact of previous hikes. The central bank could consider another increase in December or early next year if inflationary pressures persist.economictimes
