KOSPI Retreats Below 6,600 Mark Ahead of FOMC Decisions
The South Korean stock market experienced a significant correction on Thursday, April 30, 2026, with both the KOSPI and KOSDAQ indices retreating from their recent record highs. The benchmark KOSPI (KS11) and the tech-heavy KOSDAQ (KQ11) saw heavy selling pressure as investors turned cautious ahead of the upcoming Federal Open Market Committee (FOMC) meeting in the United States and dealt with a strengthening U.S. dollar.
Broad Sell-off Triggers Major Index Breaches
The KOSPI index closed at 6,598.87, down 92.03 points or 1.38% from the previous session. After hitting a new all-time high of 6,690.90 just yesterday, the index struggled to maintain its momentum, ultimately breaching the 6,600 psychological support level. Similarly, the KOSDAQ index plunged 27.91 points or 2.29%, closing at 1,192.35, falling back below the 1,200 threshold.
| Index | Closing Value | Change | % Change |
|---|---|---|---|
| KOSPI | 6,598.87 | -92.03 | -1.38% |
| KOSDAQ | 1,192.35 | -27.91 | -2.29% |
Foreign Investors Lead the Exit
Market sentiment was primarily dampened by aggressive selling from foreign investors, who recorded a net sell-off of approximately 1.45 trillion KRW in the KOSPI market and 211 billion KRW in the KOSDAQ. Institutional investors also joined the selling trend in the KOSDAQ market, while individual investors’ attempts to “buy the dip” were insufficient to stem the tide of the decline.
The primary driver for the pullback appears to be anxiety surrounding the FOMC’s upcoming interest rate decision. While many analysts expect a pause, recent inflation data has kept the market on edge. Additionally, the USD/KRW exchange rate surged today, further pressuring foreign capital to exit Korean equities.
Top Movers and Sector Performance
Blue-chip stocks that led the recent rally were the hardest hit today. Samsung Electronics (005930.KS) and SK Hynix (000660.KS) both saw significant declines as profit-taking intensified in the semiconductor sector following a month of stellar performance. LG Energy Solution (373220.KS) also retreated despite positive long-term growth forecasts.
On the KOSDAQ side, Jeju Semiconductor (080220.KQ) and Hanwha Engine (082740.KS) remained in the spotlight, though the broader weakness in secondary battery and biotech stocks weighed heavily on the index. The bearish sentiment was widespread, with 668 declining stocks in the KOSPI compared to only 194 advancers.
Market Outlook
Analysts suggest that today’s movement is a natural correction after the rapid ascent seen throughout April. “The market has been running hot on AI optimism and strong export data,” noted one Seoul-based strategist. “A period of consolidation was expected, especially with the FOMC meeting acting as a catalyst for risk-off behavior.”
