BOJ Raises Rates to 31-Year High; Japanese Stocks Rise and Yen Falls in Counter-Intuitive Market Reaction
nashnova research
The Bank of Japan raised its policy rate to 1.25% on September 18, the highest since 1995 — yet the yen weakened and stocks rallied. A 7-to-2 split vote signaled the BOJ is less hawkish than feared, cooling rate-hike expectations.
Where does this rate stand?
The policy rate now sits at 1.25%, a 31-year high, just three months after the previous hike.
This means → the BOJ is tightening at a pace of roughly once per quarter, leaving behind nearly three decades of ultra-low rates.
Why did markets move the wrong way?
The yen slid past 157 per dollar, 10-year JGB yields fell, and the Nikkei 225 rose 1.5%.
In plain terms = textbook logic says a rate hike should lift the currency and weigh on stocks — this time, every signal flipped.
The trigger was the vote split: the hike passed 7-to-2, with board members Asada and Sato dissenting. Sumitomo Mitsui chief FX strategist Hirofumi Suzuki said the two dissenting votes "caught the market off guard."
This reflects a market that cares less about *how much* the BOJ hiked and more about *whether it will keep going* — the split was read as a sign the BOJ won't push too hard.
What did the dissenters argue?
Asada noted that August core inflation was just 1.7%, down from 1.8% in July and still below the 2% target — the economy may not be strong enough.
Sato argued that current economic and price trends show no meaningful acceleration compared with earlier readings.
This means → both dissenters share one logic: the data isn't firm enough to justify the pace of tightening.
Why did the statement read dovish?
State Street senior fixed-income strategist Masahiko Loo pointed out that this hike came without an updated quarterly outlook report, limiting the BOJ's ability to reinforce a hawkish stance through revised forecasts.
Oxford Economics Japan head Shigeto Nagai added that the statement's wording was "nearly identical" to the July quarterly report — softer overall than markets expected.
In plain terms = the hike was the action, but the accompanying messaging didn't follow through — so markets concluded the BOJ's mindset is cautious.
Is the U.S. pressuring Japan to hike?
Reuters reported that U.S. Treasury Secretary Scott Bessent urged Japan to raise rates during a May meeting with Finance Minister Satsuki Katayama.
Nagai argued the two dissenting votes also signal that Prime Minister Sanae Takaichi has not fully aligned with Washington's push for faster tightening.
This reflects a reality where the BOJ's rate path is not purely an economic question — it is entangled with U.S.–Japan exchange-rate politics.
Will hikes continue? Where is the terminal rate?
Loo expects Governor Kazuo Ueda to stress that every meeting remains "live," and that the debate has shifted from "whether to hike" to "how high rates will go."
EFG International economist Sam Jochim forecasts roughly one hike every three months, with the terminal rate landing at 1.75%–2% by 2027.
Moody's Analytics Stefan Angrick expects one more hike around year-end but warns that weak demand-side inflation and disappointing real wage growth will cap further moves.
This means → whether the terminal rate reaches 2% depends on inflation and wage data improving consistently over coming quarters — and that ticket hasn't been punched yet.
