The KOSPI index plunged 8% today, triggering its eighth circuit breaker this year. The sharp drop is tied to renewed selling pressure on semiconductor and memory stocks, reflecting broader market weakness.
KOSPI wiped out 520 billion Korean won, roughly 360 billion US dollars, as investors reacted to a faltering chip sector. The decline intensified after the recent IPO of Changxin Memory Technology (CMXT) failed to inspire confidence, dragging down multiple local memory manufacturers. SK Hynix alone has lost 50% since its June peak. The turmoil parallels a sell-off in US chipmakers like Nvidia, Micron, and SanDisk, which fell between 4.4% and 10%.
Ripple effects and market sentiment
The index has fallen more than 28% over the past month, continuing a steep slide that began earlier in July. This volatility stems from a combination of retail trading swings and the outsized influence of semiconductor shares, a sector closely linked to AI developments. The KOSPI is often viewed as a benchmark for on-chain perpetual futures trading due to its liquidity and tech exposure.
Asian markets broadly mirrored KOSPI’s drop, with Japan’s Nikkei down 4%, while Bitcoin slipped below $64,000, indicating widespread risk aversion. The sell-off also affected leveraged positions backed by South Korean stocks, hinting at further downside risk through margin calls.
This year’s circuit breakers mark a record pace of trading halts, underscoring the market’s fragility amid a global chip stock correction and uncertainty over tech-driven growth. Investors will be watching closely whether this momentum continues or if a stabilization emerges.
