The Bank of Japan raised its policy rate to 1.25% on Friday, September 18, 2026. The 25-basis-point hike matched what forecasters expected and lifted borrowing costs to a 31-year high. Yet the yen fell instead of rising, because two board members voted no and Governor Kazuo Ueda made no promise of more hikes.

What Did the Bank of Japan Decide in September 2026?
The BOJ lifted its uncollateralized overnight call rate, its main policy lever, to 1.25% from 1.00%. That is a rise of 25 basis points, and one basis point equals a hundredth of a percent. The rate sets what banks pay to borrow from each other overnight, and it feeds into loans across Japan.
The new level marks the highest since 1995, and the pace stands out. The board moved three months after its June hike, faster than the six-month gaps earlier in the cycle. The vote split 7-2, with members Toichiro Asada and Ayano Sato pushing to hold steady. Asada warned that core inflation sat below 2%, so the economy might be too soft for another hike.
The September meeting produced no new forecasts. The BOJ refreshes its Outlook Report, the document holding its growth and inflation projections, only four times a year. The next update arrives on October 30.
Why Did the Yen Fall When the Bank of Japan Raised Rates?
Higher interest rates tend to lift a currency, because they pull in yield-seeking money from abroad. This time the opposite happened. The yen weakened past 157 per dollar, the 10-year government bond yield slipped, and the Nikkei 225 climbed 1.5%.
Two things explain the strange move. First, the 7-2 split told traders the board disagrees, so fast follow-up hikes look less likely. Second, Ueda offered no hawkish signal, the kind of language that points to more hikes ahead. Markets wanted a clear green light and did not get one.
The bigger force sits outside Japan. The U.S. Federal Reserve turned hawkish and lifted its own rates, so American yields still tower over Japanese ones. That gap keeps the carry trade alive, where investors borrow cheap yen to buy higher-yielding assets elsewhere. A wide rate gap plus a cautious BOJ adds up to a soft yen, even after a hike at home.
Promoted: The Yen Moved on What Traders Expected, Not Just the Hike. Want to See Those Expectations?
Friday showed a classic expectations day. The BOJ hiked, yet the yen slid because traders had already priced the move and wanted a firmer signal on what comes next. Reading the odds on future decisions can be as useful as reading the decision itself.

What Did Governor Ueda Say at the Press Conference?
Ueda kept his options open. He addressed whether the bank might deliver bigger or back-to-back hikes, and said the answer depends on the data. “There could be various possibilities. We shouldn’t rule anything out,” he told reporters.
He also flagged a balancing act. Rate rises make financial conditions less accommodative, he noted, so the bank wants to avoid tightening too fast or jolting asset prices. That caution is what markets read as dovish, meaning less eager to hike.
What Is Pushing Japan’s Inflation Higher?
Japan has battled rising prices for months. Core inflation, which strips out fresh food, eased to 1.7% in August from 1.8% in July. Even so, the BOJ sees the risk tilting up, because firms keep raising wages and prices while the public expects more inflation ahead.
Energy adds fuel to the fire. Conflict in the Middle East has kept oil prices high, and Japan imports almost all of its energy. Washington is leaning on Tokyo too, with U.S. Treasury Secretary Scott Bessent urging the BOJ to tighten faster and stop the yen from sliding. Prime Minister Sanae Takaichi favors big government spending and tax cuts, and she appointed the two dissenters.
What Does the Rate Hike Mean for Yen Traders?
The takeaway for FX traders is simple: the hike alone did not turn the yen around. The rate gap with the United States still drives the pair, and USD/JPY pushed back above 157 after the decision. Some desks warn that a run toward 160 could invite government intervention to defend the currency.
The next big test lands on October 29 and 30, when the BOJ meets again and publishes fresh forecasts. A hawkish Outlook Report could give the yen a lift, while more caution would keep the carry trade humming. Watch the wage data and oil prices between now and then, since both feed the inflation story.
