South Korea’s KOSPI dropped 2.6% Friday, mirroring Wall Street losses driven by high US producer prices, with tech giants like SK hynix and Samsung Electronics hitting the hardest. The local currency also weakened against the dollar amid ongoing geopolitical and inflation concerns.

  • Sector-level details now show technology stocks leading the selloff, with SK hynix down 4.48% and Samsung Electronics losing 3.5%, according to GN auto markets/indices: stock index. The won also weakened to 1,347.55 per dollar, reflecting broader risk-off sentiment as investors await US consumer price data.
