KOSPI Falls Below 5,800 Level Despite Easing Tensions
KOSPI Index · KOSDAQ Index
The South Korean stock market closed with mixed results on Friday, March 20, 2026. While geopolitical tensions in the Middle East showed signs of stabilizing, the benchmark KOSPI failed to maintain its earlier levels, closing down 1.01% at 5,781.20. In contrast, the secondary KOSDAQ market managed to find support, ending the week on a positive note.
Market Summary and Index Performance
The KOSPI lost 58.98 points, or 1.01%, finishing at 5,781.20. The index remained under pressure throughout the afternoon session as investors remained cautious despite a slight cooling in global oil prices. The secondary KOSDAQ index outperformed the main board, closing at 1,161.52, a gain of 1.58% from the previous session’s close of 1,143.48. Foreign investors were net sellers, continuing a trend of risk-aversion in the main board, while domestic institutions provided some support in the tech-heavy secondary market.
| Index | Closing Value | Change (Points) | Change (%) |

| KOSDAQ | 1,161.52 | +18.04 | +1.58% |
Sector Highlights and Top Movers
Technology heavyweights showed significant volatility. Samsung Electronics (005930) and SK hynix (000660) both faced downward pressure in the afternoon, while small-to-mid cap tech stocks in the KOSDAQ rose. The automotive sector, which had shown initial resilience, also ended the day mostly lower as the won remained weak against the U.S. dollar.
- Samsung Electronics (005930): Closed at 80,200 KRW (-1.2%)
- SK hynix (000660): Closed at 192,400 KRW (-1.1%)
- Hyundai Motor (005380): Closed at 238,500 KRW (-1.4%)
- LG Energy Solution (373220): Closed at 408,000 KRW (-0.9%)
Factors Driving the Market
The KOSPI market decline today was primarily driven by continued uncertainty over the long-term impact of Middle East tensions and a volatile currency market. While the KOSDAQ found support in niche technology sectors, the main board suffered from a lack of strong buying incentives from foreign participants. Analysts suggest that the market is currently in a “wait-and-see” mode ahead of key economic data releases next week.
