South Korean stocks led the regional downturn, with the KOSPI index (KS11) dropping 4.2% to close below 2,800 points, marking its steepest single-day decline in over a year. Financial and technology sectors were hardest hit, with major lenders and semiconductor exporters posting losses exceeding 5%. The broader MSCI Asia Pacific Index fell 2.1%, extending losses from the previous session. The move follows escalating regional tensions, including heightened military posturing near the Korean Peninsula and renewed trade policy uncertainty in key export markets. Investors reacted with increased caution, driving demand for safe-haven assets. The U.S. dollar strengthened against the Korean won, pushing the USD/KRW exchange rate to 1,398.40, its highest level since late 2023. Market participants are also reassessing growth outlooks amid mixed signals from global macro data. U.S. equity futures (SPY) declined 0.8% in pre-market trading, reflecting spillover concerns. The sell-off has affected not only equities but also bond yields, with 10-year Korean government bond yields rising 12 basis points to 3.47%. The broad-based equity decline has prompted increased volatility across Asian markets. Trading volumes surged in Seoul, Tokyo, and Hong Kong, while equity options markets signaled rising implied volatility. Financial institutions have begun adjusting risk exposure, with several regional hedge funds reducing long positions in cyclical sectors.
