Korean Stock Market Report — July 24, 2026
Market Overview
South Korean equities suffered a sharp broad-based selloff on Thursday, with both major indices posting losses exceeding 5% as surging international oil prices rattled investor sentiment and triggered heavy selling across virtually every sector.
The KOSPI plummeted 5.72% to close at 6,690.62, briefly breaching the psychologically significant 6,700 level during intraday trading. The tech-heavy KOSDAQ fared only marginally better, sliding 5.32% to settle at 748.22. The depth and uniformity of today’s decline suggest that macro-level concerns—rather than any company-specific catalysts—were the primary driver of today’s risk-off environment.
The spike in global crude oil prices appears to have been the principal trigger, injecting fears of renewed inflationary pressure, higher input costs for manufacturers, and potential central bank policy recalibration. Foreign investors accelerated their selling activity, compounding downward momentum across large-cap names.
Major Stocks Performance
Blue-chip stocks bore the brunt of today’s selling, with heavyweight semiconductor and automotive names leading losses.
| Stock | Price (KRW) | Change |
|---|---|---|
| Samsung Electronics (005930) | 249,500 | -7.59% |
| SK Hynix (000660) | 1,759,000 | -8.34% |
| LG Energy Solution (373220) | 329,500 | -5.32% |
| Hyundai Motor (005380) | 401,000 | -7.18% |
| NAVER (035420) | 207,500 | -5.68% |
SK Hynix was the worst performer among blue chips, dropping 8.34%, while Samsung Electronics shed 7.59%, dragging related names such as Samsung Electro-Mechanics (−8.43%) and SK Square (−9.17%) sharply lower. Hyundai Motor declined 7.18%, reflecting concerns over energy cost pressures on the automotive supply chain. NAVER and LG Energy Solution also fell in line with the broader market rout.
Market News
SK Group Chairman’s Divorce Settlement Rattles Conglomerate Sentiment A landmark court ruling ordered SK Group Chairman Chey Tae-won to pay approximately 944 billion KRW (~$680 million USD) to his ex-wife Roh So-young as part of their divorce asset division. The court apportioned assets at a ratio of two-thirds to Chey and one-third to Roh, with SK shares included in the settlement scope. The Wall Street Journal noted that the ruling could have implications for Chey’s control over the broader SK conglomerate—an overhang that contributed to pressure on SK-affiliated stocks today.
Samsung Electronics Unveils Galaxy Z Fold 8 Specs & Robot ETF Launch Samsung announced full specifications for the Galaxy Z Fold 8 and reaffirmed its expansion into AI-enabled wearables and health monitoring devices. Separately, a new robotics-focused ETF launched today allocates 25% each to Samsung Electronics and Hyundai Motor, alongside stakes in Rainbow Robotics and Hyundai Mobis—reflecting growing institutional interest in Korea’s emerging robotics ecosystem.
Oil Price Surge Amplifies Market Volatility The sudden spike in international crude oil prices acted as the immediate market catalyst, intensifying selling pressure on energy-intensive manufacturers and eroding confidence in near-term corporate earnings outlooks.
Key Takeaways
- Today’s selloff was macro-driven, with rising oil prices and risk-off sentiment overriding company fundamentals.
- The SK divorce ruling introduces governance uncertainty for one of Korea’s most strategically critical conglomerates, particularly for its semiconductor arm, SK Hynix.
- Despite near-term volatility, Korea’s long-term narratives—AI semiconductors, electric vehicle batteries, and robotics—remain structurally intact.
- Foreign investors should monitor oil price trajectories and any regulatory clarity around the SK asset settlement before reassessing entry points in affected names.
