한국 증시 긴급 브리핑 — 반도체 붕괴·환율 급등
South Korea's stock market faced a "Black Monday" hit by a double blow: a sharp decline in US semiconductor stocks and a soaring won-dollar exchange rate. The KOSPI plummeted to 7,442 points—an 8.80% intraday drop—triggering the third circuit breaker of the year, while foreign investors simultaneously dumped trillions of won and the exchange rate breached 1,560 won per dollar, sending market sentiment into freefall.

Top Gainers & Losers
Top 3 Decliners

Global Market Linkage Points
1. US Semiconductor Major Adjustment (Nasdaq AI Stocks Down 5%+)
US markets saw AI-related semiconductor firms like Nvidia plunge 5%+ in what is being assessed as a short-term overheating correction. The shock immediately transmitted to Samsung Electronics and SK Hynix in Korea, driving KOSPI's decline.
2. Strong US Employment Data → Rate Hike Fears → Dollar Strength
Following the US employment data release, Fed rate hike expectations surged, sparking a global dollar demand spike. The won-dollar rate breaching 1,560 is the direct outcome.
