South Korea's stock markets tumbled significantly after the United States announced plans to impose reciprocal tariffs. Foreign investors withdrew approximately 3 trillion won from the domestic market, contributing substantially to the market decline. In particular, as the KOSPI 200 futures index plummeted, circuit breakers were triggered as programmed selling orders became effective. Following this event, the KOSPI's market capitalization fell to 1,906 trillion won, dropping below the 2 quadrillion won mark for the first time in three months. Meanwhile, defensive stocks such as Korea Electric Power Company showed gains.
