Bank of Japan Raises Policy Rate to 1.25 Percent, a 31-Year High

The Bank of Japan raised its policy rate by 25 basis points to around 1.25 percent on 18 September 2026, the highest level for Japanese short-term rates in 31 years. The nine-member Policy Board approved the increase on a 7-2 vote.

What changed

The Board instructed the Bank to "encourage the uncollateralized overnight call rate to remain at around 1.25 percent," up from around 1.0 percent. That is a 0.25 percentage point move, and it takes the benchmark to a level last seen in 1995.

Two members dissented. Asada Toichiro argued that the recent rise in the consumer price index remained below 2 percent, leaving it unclear whether the economy was strong enough to warrant an increase. Sato Ayano took a similar line, arguing that economic and price developments had not accelerated substantially enough to make a hike appropriate now.

The accompanying statement was explicit about direction. The Bank said it "will continue to raise the policy rate and adjust the degree of monetary accommodation," and projected that the consumer price index excluding fresh food will accelerate to clearly above 2 percent from the second half of fiscal 2026. It described the economy as recovering moderately and said accommodative financial conditions are expected to be maintained even after this change.

The mechanism

For anyone holding or seeking a Japanese mortgage, the transmission channel is the short-term prime rate rather than the policy rate itself. Japanese variable-rate housing loans are priced off each commercial bank's short-term prime rate, to which the lender applies a negotiated discount for the individual borrower. Banks set that prime rate themselves. It is not automatic, and a policy decision does not change a borrower's applied rate on the day it is announced.

The timing then runs through the loan contract. Variable housing loans in Japan reset the applied interest rate on a contractual schedule rather than continuously, and most contracts contain payment-smoothing provisions that limit how fast the monthly instalment can rise. Where those provisions bind, an increase in the applied rate does not raise the payment immediately. It shifts the composition of the payment toward interest and away from principal, which extends the effective repayment profile rather than the headline monthly cost. Borrowers should read the reset date and the smoothing clause in their own loan agreement, because the two together determine when this decision reaches them.

Fixed-rate products behave differently. Bank fixed-rate offerings and the Flat 35 programme are priced against Japanese government bond yields rather than the short-term prime rate, so they reprice with the bond market rather than on a contractual reset date. A policy decision that lifts the whole yield curve reaches fixed-rate borrowers faster than variable ones.

What it means for a foreign buyer

A foreign buyer financing in yen now faces a higher floor under borrowing costs and a central bank that has said on the record it intends to keep raising. The practical consequences are three.

First, the balance of risk between variable and fixed products has shifted. A variable loan taken at today's discount will reprice at the next contractual reset against a benchmark the Bank has signalled it will raise further, not hold.

Second, affordability assessments tighten. Japanese lenders qualify applicants against a stress rate above the offered rate, and a higher benchmark moves that test upward. Foreign applicants without permanent residency already face narrower lender choice and larger deposit requirements at most institutions, so the marginal applicant is the one affected first.

Third, the currency matters as much as the rate. A higher policy rate and rising Japanese government bond yields support the yen, which raises the cost of a Japanese property in dollar or euro terms for a buyer converting funds. For a foreign cash buyer, the rate decision and the exchange rate push in the same direction.

Context

Japan spent most of three decades with policy rates at or below zero, and the current cycle is a normalisation rather than a tightening into restriction. The Bank's own statement says accommodative financial conditions are expected to persist at 1.25 percent, which is a different posture from a central bank trying to cool a housing market.

That backdrop is why Japanese property has continued to attract foreign capital through the rate cycle. The benchmark land price survey published in September showed land values still rising, with commercial land leading residential. Japan places no nationality restriction on freehold property ownership, and there is no foreign buyer tax or ownership cap of the kind now in force in several Asia Pacific markets. The obligation that does apply to foreign purchasers runs through the reporting requirements of the Foreign Exchange and Foreign Trade Act, not through any limit on what can be bought.

The Board's next scheduled meeting is the test of whether the guidance in this statement translates into another move before the fiscal year ends in March.
