South Korea’s benchmark KOSPI index has officially crossed the threshold into a technical bear market, erasing months of gains as global enthusiasm for artificial intelligence begins to sour. The index, which served as one of the world's top performers earlier this year, has plummeted 20% from its June record highs, prompting an emergency intervention from the country’s top financial regulators.
Finance Minister Koo Yun-cheol convened an urgent meeting on Wednesday with the Governor of the Bank of Korea and lead financial regulators to address what they termed a 'core risk' to financial stability. The central concern is the extraordinary concentration of the South Korean market in the semiconductor sector. As global investors pivot away from AI-heavy portfolios, the heavy weighting of firms like Samsung Electronics and SK Hynix has transformed from a growth engine into a source of systemic fragility.
The volatility has been particularly jarring given the underlying corporate performance. Samsung Electronics recently reported a staggering 19-fold increase in quarterly profits, yet its shares continued to face selling pressure. This disconnect suggests that investors are no longer trading on current fundamentals, but are instead pricing in a structural cooling of the massive capital expenditures that have defined the AI era.
Compounding the crisis is a surge in retail and institutional use of single-stock leveraged ETFs. Regulators warned that these financial products have acted as an accelerant, magnifying downward movements and triggering circuit breakers—which have already been activated six times this year. The Financial Supervisory Service has now pledged to scrutinize the marketing and impact of these leveraged products, fearing they are distorting price discovery.
Fidelity International and other global asset managers note that the current turmoil hinges on a $1 trillion question: can the few big tech giants sustaining AI demand continue their record-breaking capital spending? For South Korea, a global bellwether for the tech cycle, the answer to that question is now a matter of national economic security rather than mere market fluctuation.
