The Bank of Japan has raised its key interest rate to 1 percent, marking the highest level in 31 years as policymakers attempt to control inflation pressures linked to the Iran war. The central bank increased its short-term policy rate by a quarter percentage point from 0.75 percent, signaling a significant shift in Japan's monetary approach.
The decision reflects growing concerns about price pressures spreading through the economy. Bank of Japan officials warned that companies are passing on rising oil costs to each other at a relatively fast pace. Despite recent declines in oil prices following a U.S.-Iran peace agreement framework, the central bank proceeded with the rate increase, indicating confidence that inflationary risks warrant action even as immediate oil price pressures ease.
Central bank governor Shinichi Uchida acknowledged at a press conference that the signing of a U.S.-Iran memorandum was "a welcome move" while noting uncertainty about how quickly oil supplies would recover. He emphasized that while the risk of sharp economic deterioration from the Middle East conflict has diminished, underlying inflation concerns persist. With core inflation approaching the central bank's 2 percent target, officials said it was important to ensure that inflation stabilizes at desired levels.
The rate increase lifts Japan's borrowing costs to levels not seen since 1995, when the central bank was reducing rates following the collapse of asset prices in the late 1980s. This represents a dramatic turnaround from 2016, when Japan implemented negative interest rates in an effort to stimulate the economy and combat decades of deflation.
The move comes as major central banks respond to inflationary pressures. The European Central Bank recently raised its main interest rates, while the U.S. Federal Reserve and Bank of England are expected to hold borrowing costs steady at upcoming meetings. Japan's approach remains gradual compared to more aggressive tightening seen elsewhere.
The government has introduced a relief package to help households facing elevated fuel costs, which likely contributed to the central bank's confidence in proceeding with the rate increase. Higher borrowing costs will affect businesses and consumers across Japan, potentially moderating economic activity while helping to stabilize prices.
Markets reacted positively to the decision, with some investors viewing it as measured rather than hawkish. The Nikkei share index reached 70,000 points for the first time during Tuesday's session, closing at a new record high. The index has gained approximately one-third of its value so far this year.
The rate increase marks a watershed moment for an economy that spent much of the past three decades struggling with deflation and stagnation. Economists will monitor how Japanese businesses and households respond to higher borrowing costs and whether additional rate increases follow.
