The yen climbed to its highest level against the dollar since mid-February on Tuesday as traders increased bets that the Bank of Japan will raise interest rates at next week’s policy meeting. Strong wage growth and an upward revision to second-quarter GDP strengthened the case for a third hike this year.
July wage data released last week showed real wages up 2.4% year on year, the fastest gain since May 2021 and the seventh straight monthly increase. Nominal cash earnings rose 4.7%, the biggest jump since January 1997, with base pay up 4.1% and bonuses up 6.3%. Deutsche Bank analysts wrote that the figures reinforce the case for a hike at the September meeting, following the move three months ago in June.
Growth is stronger than first thought
Revised GDP numbers released Tuesday added to the picture. Japan’s economy grew faster in the second quarter than initially estimated, the Japan Times reported, giving the central bank room to tighten without worrying about choking off recovery. Governor Kazuo Ueda signaled as much after the July meeting, saying it is possible to accelerate the pace of hikes.
Politics is part of the story too. The yen’s rally follows an unusual joint intervention by Japan and the United States in August, after Ueda’s comments were read in Washington as a signal that a September hike was coming. US Treasury Secretary Scott Bessent said at the time he expected policy follow-up. Economists, including Mizuho’s Shintaro Inagaki, described the intervention as effectively creating a situation where Japan owes the US a favor, one that gets repaid with a rate rise.
The wage streak itself is the structural argument. The 2026 shunto spring wage talks delivered average increases of 5.01%, a third consecutive year above 5%, and companies have kept passing gains into monthly pay. Labor shortages and a shrinking workforce mean firms have little choice but to keep raising wages, which keeps services inflation sticky and keeps the BOJ’s tightening case alive regardless of one weak month here or there.
What a hike would mean
Markets have been positioning for this. The yen’s move is the cleanest expression of it, but Japanese bank stocks and JGB yields have also priced a fair chance of tightening. A hike would be the third of the cycle, following the June move. Analysts including Takuji Aida project the BOJ will continue raising at roughly one increase per quarter into early next year.
For global markets the timing is awkward. Brent crude crossed $100 a barrel on Tuesday, a seven-week high, and Fed rate-hike odds have been climbing after a run of hot US data. Two major central banks tightening into an oil shock is the combination investors like least, and it showed: the Sensex fell 555 points to its lowest close since mid-June, the Hang Seng dropped 0.5% for a second day, and US futures pointed lower with this week’s CPI print as the swing factor.
The risks to the trade
The bull case for the yen is not airtight. Japan’s export-heavy economy has historically suffered whenever the currency strengthens too fast, and the government has spent heavily on interventions to weaken the yen in past years. The Takahashi administration previously pushed back on rapid hikes for exactly that reason. If the BOJ goes too far and growth rolls over, the hike cycle could pause, and long-yen positions built up over the past two weeks would unwind quickly.
The meeting itself carries event risk. Ueda has surprised before, and the statement and press conference will be parsed for hints on the pace of future moves. Most economists expect a hike plus a hold on guidance, rather than an explicit quarterly roadmap. Anything firmer would push the yen through recent ranges; anything softer and the six-month high could mark the top.
Decision comes next week. Until then, expect thin liquidity, choppy yen pairs and every wage or GDP revision to move markets more than it normally would.
