South Korean KOSPI market volatility

Overview

The South Korean KOSPI index underwent extreme volatility following a massive selloff in July, where the index lost approximately 40% of its value from its June peak. This decline was primarily driven by the unwinding of leveraged retail positions in AI-related semiconductor stocks, including Samsung Electronics and SK Hynix. The market volatility peaked on July 28 with a single-day decline of 10.84%, erasing over $2 trillion in market value and triggering circuit-breaker halts. In response, South Korean regulators implemented measures to curb speculation, such as raising barriers to trading single-stock leveraged ETFs and tightening margin trading requirements.

While the market showed signs of a rebound in early August, subsequent reports indicated that a decline in the KOSPI has been linked to the stabilization of the exchange rate. By early September, the KOSPI showed signs of recovery, rising 16.76 points to close at 6,579.48. This rebound followed a significant plunge caused by Middle East tensions and concerns regarding U.S. Federal Reserve interest rate hikes.

By September 5, 2026, the KOSPI approached the 7,000-point mark, driven by optimism surrounding artificial intelligence. The release of OpenAI’s new AI model, ‘Astra,’ fueled expectations for increased demand for high-capacity memory products, benefiting major chipmakers like SK Hynix and Samsung Electronics. SK Hynix shares rose over 8% during this period. This rally was supported by massive net purchases from foreign investors and record-breaking economic data; South Korea’s cumulative exports from January to August reached $709.4 billion, surpassing the previous year’s full-year total. Specifically, semiconductor exports saw explosive growth, with August figures showing a 209% year-on-year increase.
