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 approached the 7,000-point mark, driven by optimism surrounding artificial intelligence and the release of OpenAI’s ‘Astra’ model. However, the index recently faced a two-day slump, losing nearly 150 points. On September 13, 2026, the KOSPI dropped over 3% as the semiconductor sector led a sharp market decline. This downturn followed a call from Anthropic’s chief executive to ‘slow AI development’, impacting companies supplying memory chips for AI servers.

By early October, the KOSPI recovered the 7,000 level, supported by a significant surge in semiconductor exports. As of October 4, 2026, the KOSPI continues to fluctuate around the 7,000 level, characterized by institutional buying despite net selling by foreign investors. Market sentiment is being bolstered by strength in the US Nasdaq and Nvidia, alongside domestic developments such as Samsung Electro-Mechanics securing a 290 billion won contract for AI server-grade MLCCs and announcing a 4.27 trillion won investment to expand FC-BGA production facilities. Investors remain focused on upcoming third-quarter preliminary earnings from Samsung Electronics.
