South Korean stocks suffered a series of trading suspensions on Tuesday, as a selloff in chipmakers spread across sectors. The KOSPI index triggered circuit breakers after Samsung Electronics and SK Hynix shares plunged sharply, forcing exchanges to pause trading multiple times. The rout reflected global semiconductor weakness and mounting concerns over demand outlook. Authorities moved to stabilize markets as volatility spilled into broader financial shares and the won currency.

The Financial Services Commission signaled readiness to deploy stabilization measures if needed. Analysts cited weakening memory chip prices and cautious guidance from major tech firms as catalysts. Foreign investors accelerated selling, exacerbating the decline. Trading halts aimed to prevent panic-driven moves and allow information dissemination.

Market participants await clarity on export data and central bank policy response. The episode underscores Korea's heavy reliance on semiconductor exports and sensitivity to global tech cycles. Regulators emphasized market resilience while monitoring systemic risks.
