South Korean Won Falls to 1,342 as Foreign Investors Dump Semiconductor Stocks
The South Korean won weakened to around 1,342 per US dollar, reversing recent gains as heavy foreign capital outflows from domestic equities increased demand for the US currency.
The pressure on the won comes amid a sharp selloff in South Korean shares, particularly semiconductor stocks, with foreign investors selling a net KRW 1.26 trillion worth of domestic equities. The KOSPI fell nearly 4%, reflecting concerns that a Democrat-led US Congress could introduce tighter regulations targeting artificial intelligence (AI) and data centres.
The currency’s decline is notable because it has occurred despite broader weakness in the US dollar and a record South Korean current account surplus. Robust semiconductor exports supported a surplus of $61.46 billion in September, highlighting the contrast between strong external trade fundamentals and deteriorating portfolio investment flows.
Year to date, the won has depreciated by 6.95% against the US dollar, keeping the currency under pressure despite recent periods of recovery.

Current Won Price Action
The South Korean won has reversed its recent gains, weakening towards 1,342 per dollar as foreign investors reduce exposure to domestic equities.
The scale of the equity selling has become an important factor for the foreign-exchange market. When international investors sell South Korean shares, they may convert the proceeds back into foreign currencies, including US dollars. This can increase demand for dollars and add downward pressure on the won.
The latest currency movement also highlights the influence of financial-market flows. South Korea’s strong trade position and current account surplus have not been sufficient to offset the immediate impact of foreign portfolio outflows.
Foreign Investors Accelerate Equity Selling
Foreign investors sold a net KRW 1.26 trillion worth of South Korean shares, contributing to the sharp decline in the KOSPI.
Semiconductor stocks were particularly affected as investors assessed the potential implications of tighter US regulation on AI and data-centre industries.
Concerns surrounding a Democrat-led US Congress have raised the possibility of additional regulatory restrictions affecting the technology sector. Given the importance of semiconductor companies to South Korea’s equity market and export economy, these concerns have contributed to the wider market selloff.
The Korea Exchange activated a sell-side sidecar following the sharp decline, temporarily suspending program trading in KOSPI-listed shares for five minutes. The intervention underlines the intensity of the selling pressure and the volatility experienced across the domestic equity market.
Semiconductor Sector Remains Central to Currency Sentiment
South Korea’s semiconductor industry is a major component of its export performance and international investment profile.
The sector’s importance creates a direct connection between technology-sector sentiment, foreign equity flows and the won. When investors become concerned about the outlook for semiconductor companies, the impact can extend beyond share prices into currency markets.
The latest concerns over potential US AI and data-centre regulation have therefore created a challenging environment for South Korean assets, despite the country’s strong export performance.
Whether these concerns translate into sustained regulatory changes remains an important uncertainty for investors.
Record Current Account Surplus Provides Fundamental Support
South Korea recorded a current account surplus of $61.46 billion in September, supported by robust semiconductor exports.
A strong current account position generally provides support for a country’s currency by reflecting the strength of external trade and income flows. However, the latest won depreciation demonstrates that positive external balances do not guarantee immediate currency appreciation.
In the current environment, foreign portfolio investment flows are exerting considerable influence over the exchange rate.
The contrast between the record surplus and the won’s 6.95% year-to-date depreciation highlights the importance of distinguishing between trade-related currency flows and movements in international investment capital.
Bullish Sentiment
- Record current account surplus: September’s $61.46 billion surplus highlights the strength of South Korea’s external position and provides a potential fundamental support for the won.
- Strong semiconductor exports: Robust technology exports continue to underpin the country’s trade performance and demonstrate the importance of the sector to the wider economy.
- Potential stabilisation in equity markets: Any reduction in foreign selling could ease demand for US dollars and help the won recover some of its recent losses.
- Broader US dollar weakness: The won’s depreciation has occurred despite a weaker dollar environment, meaning a stabilisation in domestic investment flows could provide scope for currency recovery.
Bearish Sentiment
- Heavy foreign equity outflows: Net selling of KRW 1.26 trillion in South Korean shares has increased pressure on the won through demand for foreign currencies.
- Semiconductor sector weakness: Continued selling of technology stocks could undermine investor confidence in one of South Korea’s most important export industries.
- Potential US regulatory restrictions: Concerns about tighter AI and data-centre regulation could weigh on semiconductor valuations and foreign investment appetite.
- Negative year-to-date performance: The won’s 6.95% depreciation against the US dollar highlights the currency’s broader weakness and leaves it vulnerable to further selling pressure.
South Korean Won Forecast: What Traders Are Watching
The immediate outlook for the won will depend heavily on whether foreign investors continue reducing their exposure to South Korean equities.
The currency’s weakness despite a broader decline in the US dollar suggests that domestic capital flows are currently a significant influence on USD/KRW.
Three developments will be particularly important:
- Foreign equity investment: A reduction in net selling could ease conversion demand for US dollars and help stabilise the won.
- US technology regulation: Any further clarity on potential restrictions affecting AI, data centres and semiconductor companies could influence investor sentiment towards South Korean equities.
- Semiconductor export performance: Continued export strength would reinforce the country’s external fundamentals and potentially provide longer-term support for the currency.
If foreign selling persists and semiconductor stocks remain under pressure, USD/KRW could face further upward pressure. Conversely, a recovery in equity-market confidence and continued export strength could help the won regain ground.
External Balance and Capital Flow Outlook
South Korea’s record September current account surplus provides an important counterweight to the recent weakness in the won.
However, the latest developments demonstrate that the currency can remain under pressure when portfolio investment flows move against the domestic market.
The sustainability of the external surplus, semiconductor export performance and the direction of foreign investment will therefore remain important considerations for the currency outlook.
Market Outlook for the Coming Sessions
The South Korean won faces competing forces. Strong semiconductor exports and a record current account surplus provide fundamental support, while foreign equity outflows and concerns about potential US technology regulation are weighing on market sentiment.
The decline in the KOSPI and activation of the Korea Exchange’s sell-side sidecar highlight the intensity of the recent market disruption.
For the coming sessions, traders will be watching foreign investor activity, semiconductor stock performance and developments surrounding US regulatory policy. Continued capital outflows could keep the won under pressure, even if the broader US dollar remains weak.
A stabilisation in domestic equities, combined with continued strength in exports, could help restore confidence. For now, the direction of foreign investment flows appears central to the near-term outlook for USD/KRW.
Today Markets Analysis
The won’s decline towards 1,342 per dollar illustrates how capital flows can outweigh positive trade fundamentals in the short term.
South Korea’s $61.46 billion current account surplus and robust semiconductor exports provide evidence of underlying economic strength. However, foreign investors are currently responding to concerns about technology-sector regulation and the potential implications for semiconductor valuations.
The resulting equity outflows have increased demand for US dollars, putting pressure on the won despite broader dollar weakness.
The key issue for the currency is whether the recent selling represents a temporary adjustment in investor positioning or the beginning of a more sustained reduction in foreign exposure to South Korean assets.
Currency Hedger View
For South Korean importers, exporters and international businesses trading with Korean counterparties, movements in USD/KRW can materially affect transaction costs, payment obligations and profit margins.
The won’s year-to-date depreciation of 6.95% highlights the importance of managing currency exposure where commercial contracts involve US dollar payments or receipts.
A weaker won can increase the local-currency cost of dollar-denominated imports and foreign obligations, while potentially improving the local-currency value of dollar export receipts. The actual impact depends on the direction of the transaction and the company’s underlying exposure.
Businesses with future USD/KRW payments or receipts should assess their exposure, settlement dates and cash-flow requirements when considering appropriate foreign-exchange risk-management strategies.
