South Korean KOSPI Plunges 8.2% as Tech Stocks Suffer Massive Sell-Off
South Korea's KOSPI index plunged 8.2% amid US inflation fears and a tech sell-off, triggering a circuit breaker. Concurrently, the president shared data showing a decline in suicides, urging citizens to seek help.

The South Korean KOSPI index plummeted by 8.2% to its lowest level in roughly three months. The unusual drop triggered the automated circuit breaker mechanism, halting trading on the Seoul bourse. The crash was fueled by higher-than-expected US inflation data reaching 3.7%, which heightened concerns that interest rates would remain elevated, alongside a global wave of profit-taking in tech stocks and waning optimism surrounding artificial intelligence investments.
Tech Sector Slump
South Korean semiconductor stocks suffered the hardest blow. Samsung Electronics shares plunged by 9.7%, while SK Hynix lost 11.1%, partly due to growing competition from Chinese memory chip maker ChangXin. These declines add to a prolonged negative trend in which the KOSPI index has lost more than over 40% of its value since its peak last June. This trend reflects a reassessment and cautious investor stance regarding tech company valuations and profit forecasts.
Presidential Appeal Amid Market Turmoil
Amidst the market turmoil, the South Korean president published a chart on X from the Korea Institute for Health and Social Affairs (KIHASA) showing changes in the number of suicide cases in the country during the first half of 2026 compared to the same period in 2025. Alongside the chart, the president wrote: > "You must live. At all costs, you must live. If you are struggling, call 109." This is the number for South Korea's national emergency hotline for suicide prevention and mental health support.
Data showed that the number of suicide cases in the country dropped by more than 10% in the first half of the year. The most prominent finding is that 53.4% of the overall decrease stemmed from cases tied to financial distress, pointing to the potential contribution of debt-relief programs and financial assistance. Meanwhile, psychiatric issues remained the most common factor in absolute numbers with 2,393 cases, though registering a modest 2.6% decline.
