The South Korean won advanced past 1,400 per dollar for the first time since Oct. 2, 2025, when it traded at 1,399.5. As of 5:30 p.m. Monday in Seoul's onshore market, the won quoted at 1,418 per dollar, with a further 10-won strengthening needed to breach the 1,300-won range.
The rally reverses a sharp sell-off that pushed the won to 1,550 per dollar in just over a month—its sharpest volatility since the 2008 financial crisis. The rebound reflects a confluence of supply-side factors with defined catalysts.
SK Hynix's recent American depositary receipt listing has generated dollar conversion flows into won, providing direct bid-side support. Simultaneously, foreign investors' net selling of Korean equities collapsed to 9.81 trillion won ($6.9 billion) in July, down 79 percent from 47.03 trillion won in June, according to Korea Exchange data.
U.S.-Japan joint intervention to support the yen created a secondary tailwind. The won and yen exhibit tight correlation in forex markets; the won is now benefiting from yen strength after having been dragged lower by its prior weakness.
Weaker-than-expected U.S. employment data further pressured the dollar, reducing market expectations for Federal Reserve rate increases this year.
Yuanta Securities economist Kim Ho-jung attributed the strengthening to supply factors with defined deadlines: SK Hynix's conversion and Korea's April inclusion in the World Government Bond Index. That WGBI admission is expected to generate inflows through November.
The volatility magnitude is striking. From July 2 through Aug. 7—25 trading days—the won gained 139.7 won per dollar, an average daily gain of 5.6 won, more than double the 2.5-won average recorded between April 9 and June 30 in the prior year.
Kim projects a year-end median exchange rate of 1,371 won per dollar and maintains his third-quarter outlook for continued won strength, irrespective of the precise magnitude of these supply effects.
