South Korea’s currency markets are experiencing a historic bout of turbulence, with the value of the won against the US dollar plunging to levels not seen since the global financial crisis of 2009. On the morning of June 8, 2026, the won-dollar exchange rate opened at 1,555.2 won, marking a 17-year and three-month high, according to Yonhap News. This dramatic weakening of the won has sent ripples across financial markets, triggered circuit breakers on the KOSPI stock index, and prompted urgent interventions by Korea’s top financial authorities.
In the days leading up to this milestone, the won’s depreciation accelerated at a pace far outstripping other major currencies. While the US dollar index rose just 1.2% in June, the won tumbled 3.48%, a sharper drop than even the politically unstable Indonesian rupiah or the Argentine and Philippine pesos, as relayed on YTN Radio. The airport bank counter rate for cash dollars surpassed 1,600 won, hitting 1,624 won at one point, creating headaches for travelers and importers alike.
What’s behind this currency drama? The answer lies in a complex interplay of global and local forces, but one factor stands out: a massive and sustained sell-off of Korean stocks by foreign investors. Since the start of 2026, foreign investors have dumped more than 118 trillion won in Korean equities, including over 44 trillion won in May alone and another 18 trillion won in just the first four trading days of June, according to data cited by YTN and MBC. This exodus has created huge demand for dollars as investors convert their won proceeds, sending the currency tumbling.
But there’s more to the story. The Korean stock market, especially the tech-heavy KOSPI, had surged dramatically earlier in the year, with blue chips like Samsung Electronics and SK Hynix swelling in value. This prompted global funds to rebalance their portfolios—selling off Korean shares to maintain their desired asset mix. As YTN Radio’s Hur Ran explained, “Global asset managers, seeing their Samsung and SK Hynix holdings balloon, have been mechanically rebalancing, selling stocks and exchanging the proceeds for dollars.”
Some foreign investors have even employed currency hedging strategies, buying Korean stocks while simultaneously betting against the won. Meanwhile, Korean export giants flush with record semiconductor sales aren’t helping matters. Instead of converting their dollar earnings into won, many are reinvesting abroad, depriving the domestic market of much-needed dollar supply. This phenomenon has been dubbed the “DRAM dollar” effect, likened to the “petrodollars” of Middle Eastern oil exporters, as noted by a senior fellow at the US Council on Foreign Relations interviewed by YTN.
All this comes despite South Korea’s economic fundamentals remaining strong. The country is on track for GDP growth above 2% in 2026, unemployment and inflation are relatively stable, and the current account surplus reached about $100 billion by April—nearly 150 trillion won, as reported by MBC. The disconnect between these solid fundamentals and the won’s rapid decline has left many scratching their heads. “Even with a record current account surplus, the dollars earned aren’t being converted into won, so they don’t stabilize the currency,” Hur Ran explained on YTN Radio.
Market volatility has been further exacerbated by global events. The collapse of US-Iran peace talks and the resultant surge in oil prices—West Texas Intermediate crude jumped nearly 10% in May to over $90 a barrel—has stoked inflationary fears. At the same time, US semiconductor stocks fell more than 8% on June 6, pulling down Korean leveraged ETFs by 40% and intensifying the sell-off in Korean equities. The result? A rare “triple whammy” of weakness in Korean stocks, bonds, and the won, as described on YTN.
The authorities have not stood idly by. On June 8, the Bank of Korea and the Ministry of Economy and Finance issued a joint statement, declaring, “We will not tolerate excessive volatility and one-sided speculation in the exchange rate market,” and pledging “strong market stabilization measures including verbal intervention.” They specifically blamed speculative trading in offshore NDF (non-deliverable forward) markets for amplifying the won’s swings, as reported by Yonhap News TV. The government has also begun investigating possible market manipulation and illegal trading practices, such as companies accelerating import payments or delaying export receipts to profit from the rising exchange rate.
Yet, these interventions have so far failed to halt the won’s slide. Market participants remain unconvinced that authorities can reverse the trend, with many betting that the exchange rate will continue to rise—possibly breaching the 1,600 won barrier. As Hur Ran put it, “Verbal intervention can slow the pace, but it can’t change the direction.” Some experts warn that if foreign investor holdings in KOSPI drop by just 2%, it could trigger another 150 trillion won in stock sales, putting even more pressure on the currency.
Korean Investment & Securities analyst Moon Down assessed the situation bluntly in a June 8 report: “The current exchange rate surge is excessive both absolutely and relatively. But as long as expectations for further increases persist, the rate can go even higher.” He cautioned that the market is now in a self-fulfilling cycle—expectations of a weaker won drive more demand for dollars, which in turn further weakens the won. Moon also warned that upcoming global events, including the prolonged war, new tariffs, US inflation data, and the Federal Reserve’s next meeting, could keep the pressure on the won. “The only real turning point for the won will be when the war ends and the dollar weakens,” he said, adding that high exchange rates could become the new normal in a few years.
Meanwhile, the pain is being felt on Main Street. The spike in the exchange rate is making imported goods and overseas travel more expensive, squeezing consumers and businesses. Inflationary pressures are mounting, and the risk of widening inequality and weaker domestic demand looms large. The circuit breaker that halted KOSPI trading on June 8—triggered after an 8.37% plunge within minutes of the market opening—was a stark reminder of the market’s fragility.
Looking ahead, experts are divided on where the won goes next. Some predict continued volatility, with the exchange rate fluctuating between 1,470 and 1,600 won in the second half of 2026. Others argue that if foreign investor outflows stabilize and economic fundamentals hold, the won could gradually recover to the high 1,400s. For now, though, the only certainty is uncertainty—and a wary eye on the currency board.
