- The Korea Composite Stock Price Index (KOSPI) plummeted during Thursday's trading session, significantly impacted by the overnight escalation of geopolitical tensions in the Middle East. This led to a rapid spread of risk aversion, resulting in a net foreign capital outflow of 1.8 trillion won. With overall market investment sentiment dampened, large-cap stocks generally experienced varying degrees of pullback, with funds showing a strong inclination towards safe-haven assets.
- Despite macroeconomic fundamentals indicating that South Korea's exports surged by 85.9% year-on-year in the first 10 days of June, driven by strong semiconductor sales, heavyweight stocks like Samsung Electronics (005930:KR) were generally under pressure. The market was only temporarily buoyed by a significant intraday rebound in SK Hynix (000660:KR), which partially recovered some losses, but it was insufficient to reverse the overall downward trend.
- The pressure of capital outflow simultaneously transmitted to the foreign exchange and fixed income markets, with the Korean won weakening significantly against the US dollar (USDKRW), closing at 1,528.5 won domestically. Meanwhile, the yields on South Korea's three-year and benchmark ten-year government bonds both rose slightly by 0.7 basis points, reflecting cross-asset synchronized volatility.
Geopolitical Risk Escalation Triggers Broad Capital Outflow
The US military announced a new round of airstrikes on multiple targets within Iran overnight, and President Trump vowed to launch more attacks if a peace agreement could not be reached. This news caused a sharp premium on global geopolitical risks. As a result, risk appetite in the Asia-Pacific market significantly declined, with foreign investors making a net sell-off of 1.8 trillion won in the Korean market, equivalent to approximately 1.18 billion USD. This dealt a heavy blow to the KOSPI after the market opened, with the intraday maximum decline reaching 4.4%. Although some bottom-fishing funds flowed in, narrowing the decline in the afternoon, it still fell by 141.39 points, or 1.83%, closing at 7,589.43 points by the end of the session. The market overall showed a clear downward pressure, with only 265 out of 921 traded stocks rising, while as many as 622 stocks fell.
Divergence in Chip Giants and Pressure on Heavyweight Sectors
Among index heavyweight stocks, the semiconductor sector, a market pillar, exhibited an extremely rare divergence. Industry leader Samsung Electronics (005930:KR) could not withstand the wave of foreign sell-offs, with its stock price remaining sluggish throughout the day, ultimately closing down 2.15%. In stark contrast, SK Hynix (000660:KR) demonstrated strong resilience against the decline, surging against the trend with buying support, and ultimately recording a 0.59% gain. Its sharp intraday rebound was also a key force in temporarily recovering the broader market. In comparison, other core industry heavyweight sectors showed widespread pressure. Battery manufacturing leader LG Energy Solution (373220:KR) closed down 1.82%; automotive giants Hyundai Motor (005380:KR) and Kia Motors (000270:KR) were not spared, recording significant declines of 3.99% and 5.07%, respectively; traditional heavy industry POSCO (005490:KR) fell 4.68%, while the biopharmaceutical sector's Samsung Biologics (207940:KR) also recorded a 2.23% pullback.
Strong Trade Data Provides Macroeconomic Support
Despite the short-term sentiment setback in financial markets due to geopolitical conflicts, South Korea's domestic macroeconomic fundamentals showed resilient growth against the trend. The latest official trade data revealed an astonishing 85.9% year-on-year surge in export value for the first 10 days of June, driven by the ongoing demand for advanced semiconductor chips in the global tech cycle. This exceptionally strong growth in overseas orders underscores South Korea's critical position in the international trade of core industrial chains and provides substantial bottom support for the equity market's valuation correction. Analysts generally believe that while high-frequency macro trade data cannot fully offset the short-term outflow of risk-averse funds, if this strong export momentum driven by chip sales continues throughout June, South Korea's economic growth trajectory is expected to remain stable, which will reshape overseas investors' confidence in Korean assets in the medium to long term.
Currency and Bond Market Turmoil Reflects Cross-Asset Risk Pricing
With risk aversion dominating, the withdrawal of funds was not limited to the stock market but also profoundly altered the pricing dynamics in the foreign exchange and bond markets. On the domestic foreign exchange trading platform, the Korean won showed significant weakness against the US dollar (USDKRW), closing at 1,528.5 won per dollar, a sharp decline of 0.54% from the previous trading day's closing price of 1,520.2 won. In the fixed income market, the most liquid South Korean three-year government bond June futures (KTBc1) fell slightly by 0.04 points to 103.09. This led to an upward shift in the corresponding government bond yield curve, with the three-year South Korean government bond yield rising by 0.7 basis points to 3.897%, and the benchmark ten-year South Korean government bond yield simultaneously rising by 0.7 basis points to 4.283%. The rise in government bond yields indicates that during periods of external turmoil, the market is not only pricing in the risk of capital outflows but also reassessing potential imported inflation and geopolitical premiums.
Forward-Looking Variables and Policy Space Pricing
Looking ahead, the short-term pricing logic of South Korea's financial markets will heavily depend on the subsequent developments of the Middle East conflict. If the conflict leads to a long-term rebound in international oil prices and commodity prices, South Korea, as an energy-dependent economy, may face severe imported inflation pressure, which could further constrain the Bank of Korea's monetary policy adjustment space in response to economic fluctuations. Conversely, if the geopolitical stalemate can be resolved through diplomatic means, coupled with the currently outstanding export fundamentals, the Korean market may experience significant valuation recovery. In this highly uncertain environment, most institutional investors tend to maintain defensive positions and closely monitor changes in international energy market supply and the future policy rate path of the Federal Reserve (Fed).
