Global markets stabilize as the yen's sharp swings prompt warnings from Tokyo officials of potential intervention, fueling speculation on the currency’s future direction amidst high volatility and sustained risk appetite.
Global markets steadied on Friday as traders kept their attention on the yen, which swung sharply after another abrupt move fuelled fresh suspicion that Japanese authorities had stepped into the foreign exchange market. The dollar briefly fell by about 1% against the yen in minutes before paring losses, extending the volatility that followed a dramatic jump in the Japanese currency a day earlier.
The latest move came after Tokyo officials issued their strongest warnings yet over the weak yen. Japan’s finance minister, Satsuki Katayama, said the government was nearing the point at which "decisive action" might be needed, while top currency diplomat Atsushi Mimura also warned that intervention remained an option. Traders took those remarks, together with the yen’s sudden rebound, as a sign that policymakers were again trying to support the currency.
The yen’s swings have made it one of the main pressure points for investors this week, with the dollar having climbed to multi-decade highs against Japan’s currency earlier in the year. The latest turbulence has revived memories of last year’s intervention episodes, when Japanese authorities were also suspected of selling dollars and buying yen to slow the decline. Market participants now appear to be weighing whether Friday’s move marks the start of a more sustained official campaign or simply another short-lived squeeze.
Elsewhere, risk appetite held up. US stock indexes moved higher, helped by enthusiasm over a strong run of earnings from major technology groups that pushed Wall Street to record levels on Thursday. Most major European markets were shut for holidays, leaving trading thinner than usual, while Brent crude slipped as investors continued to assess disruptions to oil flows through the Strait of Hormuz. Global equities, meanwhile, had just logged their strongest monthly advance since 2020 in April, reflecting optimism over corporate results despite the currency and energy-market tensions.
