Bank of Japan Flags Policy Change as Markets Price a Hike to 1.25%

The Bank of Japan listed a Change in the Guideline for Money Market Operations on Sept. 18, 2026, alongside three companion Monetary Policy releases.

The listing appeared on the Bank's English-language release index. It included a reference version of the guideline change for the September 2026 Monetary Policy Meeting, an amendment to Principal Terms and Conditions of the Complementary Deposit Facility, and an amendment to Principal Terms and Conditions of the Funds-Supplying Operations to Support Financing for Climate Change Responses Bank of Japan. The listings confirm a policy adjustment was published. They do not show the new target levels on their face.

The timing fits the scheduled Sept. 17-18 meeting. That two-day window was the pre-announced date for the September decision Reuters.

Heading into that meeting, expectations pointed to higher rates. A September Reuters poll showed the Bank would raise its policy 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 percentage point, so 25 basis points equal 0.25 points Reuters. Reuters described a move to 1.25% as taking rates to a 31-year high Reuters.

The starting point was 1%. At the June 15-16 meeting the Board raised the policy rate to around 1.0 percent, according to a Sept. 2 speech text summarizing the decision. The June guideline change set the basic loan rate under the complementary lending facility at 1.25 percent Bank of Japan. Minutes of that meeting record the basic loan rate as raised by 0.25 percentage points to 1.25 percent. The Board then left the rate at 1% on July 31, a result all 52 economists surveyed by Bloomberg had predicted Bloomberg.

That June move to 1% was described by Bloomberg as a rise to 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 policy 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 steers overnight borrowing, not only the headline rate. Think of a hallway with a floor and a ceiling. The money-market guideline sets the target for the overnight call rate in the middle. The deposit facility amendment sets the floor. The lending facility sets the ceiling. The parallel change to the climate-response lending operation affects how the policy rate applies to that targeted lending. For ordinary savers and borrowers, the test is whether deposit and loan rates follow. For trading desks, the questions are pass-through to TIBOR and commercial paper, demand for collateral at the ceiling, and take-up of subsidized operations once the applied rate shifts.

In my view, the run from June through September looks gradual. Hold in July. Move in September if the priced path holds. Point toward 1.5% by fiscal year-end and 1.75% the next quarter. That pace would keep inflation-adjusted rates tight only slowly while leaving the Board room to decide meeting by meeting on wages and price updates. The risk for JGB duration and yen basis is not one 0.25-point step. It is that investors reprice toward a 1.75% end point faster than previously assumed.
