Japan May Raise Interest Rates Again — What It Means for Your Money

The Bank of Japan published a change to its interest-rate policy on Sept. 18, 2026, with three related policy papers.

The notice was on the Bank's English-language release page. It included a reference version of the change for the September 2026 policy meeting, a change to the rules for its Complementary Deposit Facility for banks, and a change to the rules for its special lending to support climate-change projects Bank of Japan. The listings show a policy change was published. They do not show the new rate levels.

The timing matches the scheduled Sept. 17-18 meeting. Those two days were the pre-announced dates for the September decision Reuters.

Before the meeting, most forecasters expected higher rates. A September Reuters poll showed the Bank would raise its main rate to 1.25% on Sept. 18 Reuters. Markets had nearly fully priced a 25-basis-point move to 1.25%. A basis point is one-hundredth of a point, so 25 of them mean 0.25 points Reuters. Reuters described 1.25% as a 31-year high Reuters.

Rates started at 1%. At the June 15-16 meeting the Bank raised its main rate to around 1.0 percent, according to a Sept. 2 speech summarizing the decision. The June change set the basic loan rate for banks at 1.25 percent Bank of Japan. Meeting minutes record that loan rate as up 0.25 points to 1.25 percent. The Bank then left rates at 1% on July 31. All 52 economists surveyed by Bloomberg had predicted that hold Bloomberg.

The June move to 1% was described by Bloomberg as a 31-year high Bloomberg. It followed a Dec. 19, 2025 increase to the highest level in 30 years Bloomberg. Kazuo Ueda was Governor in December 2025.

Analysts polled by Reuters in September expected the main rate to reach 1.5% by end-March 2027 and 1.75% in the second quarter of 2027.

The broader context here is how the Bank keeps daily rates in place. Picture a room with a floor and a ceiling. The main guideline sets the target in the middle for overnight loans between banks. The deposit rule sets the floor. The loan rule sets the ceiling. The climate-program change affects how the main rate applies to that special lending. For savers and borrowers, the question is whether bank savings and loan rates follow. For markets, the questions are pass-through to TIBOR and commercial paper (CP), demand at the ceiling, and use of the special lending once the rate shifts.

In my view, the pattern since June looks slow and steady. Hold in July. Move in September if market pricing holds. Point to 1.5% by fiscal year-end and 1.75% the next quarter. That pace leaves room to watch wages and prices at each meeting. The risk for JGB duration and yen basis is not one 0.25-point move. It is that investors start expecting 1.75% sooner than previously thought.
