South Korea’s Kospi index experienced a sharp decline on Wednesday as widespread selling in global semiconductor stocks led to significant losses for major firms such as SK Hynix and Samsung Electronics, activating a temporary trading suspension mechanism.
As of 9:37 AM (Bangkok time), the Kospi dropped by 5.42% to 6,497.81 points after having fallen as much as 6.4% earlier in the session. Shares of SK Hynix declined 6.56%, while Samsung Electronics lost 5.40%. Both companies were key contributors to the index’s overall weakness.
This sharp retreat followed a major selloff in U.S.-listed semiconductor equities, with the Philadelphia Semiconductor Index posting a 5.6% decrease—the steepest single-day decline since July. Memory chip producers were under extreme pressure, as Micron Technology slid 7% and U.S.-traded SK Hynix shares lost 9.2%. Nvidia also moved lower by 2.3%.
