The Bank of Japan’s decision at its Sept. 17–18, 2026 meeting pushed markets as traders parsed mixed signals: a BOJ rate hike in a split vote left foreign exchange, bond, and equity markets recalibrating.
Policy Shift and Vote
The BOJ raised its policy interest-rate target for the uncollateralized overnight call rate to around 1.25% from around 1.0%, the highest level since 1995, the bank said in a statement on Sept. 18, 2026. It set the Complementary Deposit Facility rate at 1.25% and the Complementary Lending Facility basic loan rate at 1.5%. The new operational guidelines take effect on Sept. 24, 2026.
The Policy Board approved the increase by a 7–2 vote, with Toichiro Asada and Ayano Sato dissenting. The bank said it would encourage the overnight call rate to remain near 1.25% until the next meeting. It described forward guidance as changed only marginally while signaling a shift toward guarding against inflation overshooting the 2% price-stability target.
This was the first rate increase in three months and the sixth since the BOJ ended its negative-interest-rate policy in March 2024. The tightening pace is the fastest since around 1990. The bank said the policy rate now sits within an estimated neutral nominal range of about 1.1%–2.5%, a level that neither cools nor overheats economic growth.
Governor Kazuo Ueda said the bank has entered a phase focused on preventing inflation from “overshooting its target.” The BOJ added it will continue to raise rates and adjust monetary easing depending on economic activity and price developments.[11]
Yen Weakens, JGB Yields Fall, Nikkei Rises
The yen weakened after the decision as investors focused on the absence of explicitly hawkish forward guidance and the presence of two dovish dissenters. The dollar rose to about 156.90 yen from roughly 156.14 yen as traders adjusted foreign exchange positions.
Japanese government bond yields fell, with the 10-year yield declining about 4.9 basis points to roughly 2.947%. Traders said this reflected a view that the BOJ stopped short of signaling an aggressive tightening path despite the headline hike.
Japanese equities moved higher. The Nikkei 225 rose as investors interpreted the rate increase and the bank’s measured language as maintaining relatively accommodative financial conditions for now.[11]
