The decision is announced; the new rate starts September 24
The September 18 statement confirms the increase. Its effective date is September 24, so the announcement does not mean the new target applies immediately. A 25-basis-point rise is 0.25 percentage points.
The complementary deposit facility rate will be 1.25% and the basic loan rate 1.5%, also effective September 24. These facility rates serve different purposes from the overnight call-rate guideline. The policy vote was 7–2; July’s 8–1 vote belongs to the previous meeting.
Why U.S. stock investors watch the BOJ
Yen-funded carry trades borrow in yen to finance other investments. Changes in funding costs or the exchange rate can alter those positions’ economics. BIS research on August 2024 found that leveraged-position unwinds amplified market turbulence; that historical episode is context, not a forecast for this meeting.
For this decision, compare the policy message with subsequent yen, bond and equity-market moves. A hike alone does not determine whether U.S. stocks fall: expectations, positioning and other news also matter. No live market reaction is asserted here.
