South Korea's benchmark KOSPI index entered bear-market territory Wednesday as a selloff in chip stocks hit Asian markets [1, 2].
The decline signals growing investor anxiety regarding the sustainability of the artificial intelligence boom. Because the South Korean economy relies heavily on semiconductor exports, the KOSPI often serves as a barometer for global tech demand.
The index closed down five% on the day [2]. This drop pushed the KOSPI more than 20% below its record high reached in June [2].
Market analysts said the volatility is due to rising bond yields. Higher yields typically increase borrowing costs and can lower the present value of future earnings for growth-oriented companies—a dynamic that is currently weighing on Big Tech valuations [1, 2].
Investors are specifically concerned about the level of cash spending by major technology firms. There are growing questions about whether the massive capital expenditures required for AI infrastructure will translate into immediate profits, which has dampened demand for the hardware produced by Asian chipmakers [1, 2].
The selloff was not limited to South Korea but affected chip stocks across Asia [1]. The concentration of semiconductor manufacturing in the region makes these markets particularly sensitive to shifts in U.S. treasury yields and AI sentiment [1].
“The KOSPI fell more than 20% from its June record high.”
The transition of the KOSPI into a bear market reflects a pivot in investor sentiment from blind optimism about AI to a more cautious evaluation of capital expenditures. If higher bond yields persist, the cost of financing the next generation of AI data centers could slow the procurement of high-end chips, potentially leading to a prolonged correction for semiconductor-heavy economies like South Korea.
