South Korea's KOSPI Halted After 8% Plunge

Market Plunge Triggers Circuit Breaker

South Korea's KOSPI index experienced a sharp decline of over 8% on Wednesday, prompting a temporary 20-minute halt in stock trading. The significant sell-off was driven by heightened risk aversion and widespread profit-taking following a strong market rally.

Profit-Taking and Geopolitical Fears Fuel Sell-Off

The KOSPI index fell 8.1% to 5,322.93 points, activating a sell-side circuit breaker. This move came after a 7.2% slide on Tuesday, erasing substantial gains from record highs set last week. The market's vulnerability grew after a 26% rally in the first two months of 2026, which was largely fueled by optimism around artificial intelligence.

Tech and Industrial Stocks Lead the Decline

The downturn was widespread, impacting key sectors that had previously led the market's gains. Chipmaking and industrial stocks were among the worst hit. Samsung Electronics Co Ltd fell 6.5% and SK Hynix Inc dropped 4.7%, while automaker Hyundai Motor plummeted nearly 10%. Samsung's stock was also negatively affected by a report stating that mass production at its new Texas plant would be delayed to 2027.

Summary and Outlook

Market sentiment has shifted to risk-averse amid concerns over the U.S.-Iran conflict and rising energy prices. Investors are now closely watching geopolitical developments and their potential impact on inflation and global supply chains. The market's future direction will likely depend on the stabilization of these external factors.
