South Korea's KOSPI tumbles more than 7.5% in sharp sell-off

A 7.5%+ intraday crash in South Korea's KOSPI signals an abrupt risk-off shock in a major Asian equity market. Such moves typically tighten financial conditions, raise volatility, and pressure regional cyclicals and global risk assets via sentiment and cross-asset de-risking. Near-term focus shifts to potential policy response, liquidity conditions, and spillover into FX and broader Asia equity benchmarks.
