The South Korean won fell to its weakest level in 17 years on Friday, with USD/KRW closing at 1,539.1 after rising 9.4 won from the previous session. Intraday, the currency touched 1,549.1 — the highest since March 9, 2009, when the global financial crisis pushed the rate to 1,549.0. At Incheon International Airport, the USD cash buying rate briefly breached 1,600 won, hitting ordinary Koreans who travel or study abroad. The won has now remained above the 1,500 threshold for 14 consecutive trading days since breaching it on March 23, with no sign of relief. I think this is not a transient spike — the structural drivers of won weakness are compounding in ways we have not seen since the 1997 Asian Financial Crisis.
The sheer scale of the move is worth contextualizing. From late February, when USD/KRW traded at 1,420, the won has depreciated approximately 8.4% against the dollar in just over three months. That is a larger move than the won's entire 2024 depreciation of 5.7% and nearly matches the 9.2% decline during the initial COVID-19 shock in March 2020. Unlike those episodes — which were triggered by identifiable single events (US-Iran war outbreak, pandemic lockdowns) — the current weakness reflects a compounding of multiple structural factors that show no signs of reversing. I think it is crucial for investors to understand that this is not a typical cyclical depreciation but a structural re-pricing of Korea's risk premium that could persist for quarters.
To put this in perspective, the won has now weakened past the level that triggered emergency intervention in 2008 and is approaching the 1,600 psychological threshold. The Bank of Korea's foreign exchange reserves, while still substantial at $420 billion, have declined by $28 billion since January as the central bank attempts to smooth the depreciation. I've been watching currency crises in emerging markets for years, and the pattern forming in Korea — persistent foreign selling, deteriorating terms of trade from the Middle East conflict, and a government whose policy credibility is eroding — has historically preceded more aggressive depreciation episodes.
Foreign Selling Tsunami: The Primary Engine of Won Weakness
The most direct driver of the won's collapse is the relentless selling of Korean equities by foreign investors. Since May 7, offshore funds have sold Korean stocks for 20 consecutive trading days, with cumulative net selling reaching approximately 70 trillion won ($45.5 billion). On Friday alone, foreign investors dumped 3.521 trillion won ($2.29 billion) worth of KOSPI stocks, while institutions added 943.5 billion won ($613 million) to the selling pressure. Individual investors bought 4.224 trillion won ($2.74 billion), but their buying was insufficient to stem the tide.
The problem is arithmetic. When foreign investors sell Korean stocks, they convert the proceeds from won to dollars, creating demand for USD that pushes the exchange rate higher. Baek Seok-hyun, an economist at Shinhan Bank, explained it clearly: "The persistence of the 1,500-won level means dollar demand is exceeding the dollar supply coming from Korea's current account surplus. Between May 7 and June 4, the average daily foreign stock selling was about $2.1 billion, which exceeded the average daily trade surplus of about $1.5 billion last month." In plain terms: Korea is earning fewer dollars from exporting goods than it is losing to foreign investors selling stocks. This structural capital account deficit is the fundamental reason even a robust trade surplus has not stabilized the currency.
The Vicious Cycle: Weaker Won Fuels More Selling
Here is the mechanism that worries me most. A weaker won reduces the dollar-denominated return of Korean equities for foreign investors. If the KOSPI stays flat but the won depreciates 10%, a foreign investor's dollar return is negative 10%. That creates an incentive to sell more Korean stocks, which in turn creates more dollar demand and further weakens the won. This is the textbook definition of a negative feedback loop, and it has historically been very difficult to break without exogenous intervention.
This cycle is reinforced by the Broadcom-driven semiconductor selloff, which we analyzed in depth in our KOSPI Black Friday report. Korean tech stocks are the most liquid and most foreign-owned segment of the market, making them the natural vehicle for capital flight. Foreign ownership of Samsung Electronics alone exceeds 50%, and foreign ownership of SK Hynix is above 45%. Every incremental dollar of selling pressure hits the won directly because the proceeds must be converted out of the local currency.
Market participants widely agree that two conditions must be met to break this cycle. First, an end to the Middle East conflict, which would reduce risk aversion and lower oil prices. Second, stabilization of foreign equity flows. Neither seems imminent. The US-Iran negotiations remain deadlocked, and there is no catalyst on the horizon to reverse the foreign selling trajectory.
Government Intervention Fails: Verbal Warnings Meet Market Indifference
Korea's economic policymakers are running out of ammunition. Deputy Prime Minister and Finance Minister Koo Yoon-cheol issued verbal warnings on both Thursday and Friday, stating that the government would "respond with heightened vigilance" and "take necessary measures against excessive one-sided moves." The market response was barely a ripple — the won stayed above 1,540 after his comments.
Park Sang-hyun of iM Securities was blunt: "There's a limit to how much verbal intervention can calm the market. Ultimately, substantial actual intervention will be needed to douse the upward momentum. The market senses that the government's exchange rate policy stance has shifted toward tolerance of a weaker won, and that perception weakens the effectiveness of any verbal intervention."
The government's dilemma is genuine. A weaker won boosts export competitiveness for Korea's manufacturing giants — Samsung Electronics, Hyundai Motor, SK — but it also fuels import inflation, raising the cost of energy, food, and raw materials. With consumer price pressures already elevated — Korea's CPI ran at 2.9% year-over-year in May — the Finance Ministry is caught between supporting exporters and protecting household purchasing power. My view is that the government has already missed the golden window for effective intervention. The policy credibility gap is now too wide to close with words alone.
Middle East War and the Won's Geopolitical Risk Premium
The US-Iran conflict has added a significant risk premium to the won. Korea is one of the world's largest energy importers, relying on Middle Eastern crude for the majority of its oil needs. The escalation of tensions around the Strait of Hormuz threatens both energy supply routes and global oil prices, which directly impacts Korea's terms of trade.
Jeong Yong-taek of IBK Investment & Securities noted: "The direct trigger for the won's sharp ascent from the 1,420 level in late February was the outbreak of the US-Iran war and the resulting oil price surge." Since late February, the won has depreciated approximately 8.4% against the dollar, with the Middle East conflict accounting for a significant portion of that move. International oil prices have remained elevated above $85 per barrel, adding roughly $2-3 billion per month to Korea's import bill compared to pre-conflict levels.
The geopolitical risk premium embedded in the won is unlikely to dissipate quickly. The Trump administration's maximum-pressure strategy against Iran shows no signs of softening, and the two sides remain far apart on nuclear and missile program issues. For Korea — a price-taker in global energy markets with limited domestic energy resources — this means structurally higher dollar demand for energy purchases will persist as long as the conflict continues.
SpaceX IPO: A $132 Billion Drain on Emerging Markets
An unusual but meaningful factor in the won's recent weakness is the upcoming SpaceX IPO, scheduled for June 12 on the Nasdaq. The Elon Musk-led space company aims to raise up to $86 billion (approximately 132 trillion won) in what would be one of the largest IPOs in global history. Korean retail investors — who have become enthusiastic participants in US IPO markets — are expected to allocate significant capital to the offering.
Kim Yu-mi of Kiwoom Securities analyzed the potential impact: "If geopolitical uncertainties ease and foreign net selling subsides, the exchange rate could move back toward 1,400. But if foreign capital outflows continue, the won will remain under pressure despite the current account surplus." The SpaceX IPO is pulling Korean retail and institutional capital toward US equities, creating additional dollar demand at precisely the wrong time. Industry estimates suggest Korean investors could allocate between 10 trillion and 20 trillion won ($6.5-13 billion) to the SpaceX IPO, compounding the existing foreign selling pressure.
Won Outlook: Navigating the 1,500-1,600 Range
Most forecasters expect the high-exchange-rate regime to persist for the foreseeable future. Min Kyung-won at Woori Bank warned that a strong US employment report on Friday evening could shift the Federal Reserve's policy bias from cuts to hikes. "If the US employment data comes in strong, the discussion will shift from rate cuts to rate hikes, which would be read as a strong-dollar catalyst," he said. The US 5月 employment report, released Friday evening, showed 228,000 new jobs — above the 190,000 consensus — which reinforced dollar strength and added further upside pressure on USD/KRW.
Moon Da-un at Korea Investment & Securities said USD/KRW could move higher without significant resistance from current levels. "At this level, the upside could expand without clear resistance depending on domestic and external developments and supply-demand conditions. The authorities' upper-bound defense efforts could slow the pace of appreciation, but a genuine reversal requires an end to the war and a decline in oil prices."
In summary: expect the 1,500-1,600 range to be the new normal for the foreseeable future. A move below 1,500 would require either a ceasefire in the Middle East or a sharp reversal in foreign equity flows — neither of which looks probable in the near term. The Bank of Korea's foreign exchange reserves, while still substantial at roughly $420 billion, are finite, and the government has shown limited appetite for using them aggressively at current levels.
My Take
Recommendation: Hold USD-denominated positions; accumulate on dips toward 1,500. For dollar-based investors, Korean won weakness presents both risk and opportunity. If you already hold dollar-denominated assets, maintain those positions — the structural drivers of won weakness remain intact. For investors needing to move money into Korea, consider a phased conversion strategy rather than a lump sum to average out the exchange rate. I think the direction of travel is clear: until either the Middle East conflict ends or foreign investors reverse course, won weakness is the path of least resistance.
Specific actionable guidance: For Korean won holders, I recommend converting 30-40% of cash holdings to dollars or dollar-linked assets at current levels (1,530-1,550). If the exchange rate retraces toward 1,480-1,500, that would be an attractive level to add won exposure for those needing local currency. For equity investors, won weakness is another reason to favor exporters (Samsung Electronics, Hyundai Motor, shipbuilders) over domestic-demand plays like retail and construction.
Probability/Confidence: 70% that USD/KRW will test 1,580-1,600 within the next 4-8 weeks. My conviction is based on the persistence of foreign selling, the lack of credible policy response from the government, ongoing Middle East uncertainty, and the additional capital outflow pressure from the SpaceX IPO.
Risk Warning: The Bank of Korea could intervene directly at any time, potentially triggering a sharp 3-5% won rally that would punish dollar-long positions. Alternatively, a surprise de-escalation in the Middle East or a dovish shift in Fed policy could reverse the trend. Do not over-leverage — currency markets can move 50-100 pips in minutes on intervention headlines, and margin calls in leveraged FX positions can be brutal.
