What happened
The Japanese yen (JPY) rose to 153.32 per dollar on Tuesday, its strongest level since February, as traders unwound carry trades ahead of a Bank of Japan rate decision expected September 17-18. The dollar has slipped roughly 4.5% against the yen in just over a week, and the dollar index eased to 98.83 as investors awaited U.S. inflation data. Stronger Japanese growth — second-quarter GDP was revised up to 1.4% annualized — and the fastest real-wage growth since 2021 reinforced hike bets. Markets price roughly an 80% chance of a quarter-point hike, and hedge funds have already cut short-yen bets, CFTC data show.
Why it matters
The yen matters globally because Japan has long been the world's cheapest place to borrow, and investors used those cheap yen loans (carry trades) to buy higher-returning assets elsewhere. When the yen rises quickly, those trades become costly to hold, forcing investors to sell assets and buy back yen — a chain reaction that can hit stocks, bonds and other currencies. A Bank of Japan rate hike next week would make yen-funded borrowing even less attractive, potentially deepening the unwind and pressuring carry-trade currencies like the Mexican peso.
