KOSPI Plunges 7.25%, Triggers Circuit Breakers
8 Jun
Summary
- South Korea's KOSPI index fell sharply, triggering circuit breakers.
- The market drop comes despite KOSPI's strong year-to-date performance.
- Geopolitical tensions and corporate forecasts add to market uncertainty.

South Korea's KOSPI index experienced a severe drop, triggering circuit breakers and declining by roughly 7.25% in early Monday local trading. This sharp decline marks a reversal for the market, which had previously been the world's best-performing major index this year. The index is still up approximately 75% year-to-date but has lost about 15% since the previous Tuesday.
The sell-off is heavily influenced by major memory-chip manufacturers Samsung and SK Hynix. The iShares MSCI South Korea ETF, a key US-listed proxy, tumbled significantly after Broadcom issued a weaker-than-expected AI semiconductor revenue forecast.
Global markets are showing mixed reactions, with US futures exhibiting volatility. Concerns are heightened by geopolitical developments, including reports of missile firings, and by past statements from a former US President regarding Israeli policy. These factors, combined with a recent spike in Treasury yields, are creating widespread market unease.
The potential for market contagion is a significant concern, particularly for the Nasdaq, whose top holdings rely on Korean memory supply. NVIDIA's CEO, currently in South Korea, acknowledged the market dip but expressed optimism, suggesting it presents buying opportunities.
