On July 2, South Korea's benchmark KOSPI index briefly plummeted below the 8,000-point threshold during early trading, prompting the Korea Exchange (KRX) to activate a mandatory five-minute suspension of program trading. This mechanical risk-control measure was triggered by a significant selloff in the semiconductor sector, which exerted substantial downward pressure on the broader market. According to data from the Korea Exchange, the halt was implemented to mitigate extreme volatility and manage strained liquidity levels resulting from intense short-term selling. The incident underscores the current instability within the South Korean equity market and the critical role of automated safeguards in maintaining orderly trading during periods of high-volume institutional divestment.
