KOSPI Plunges 3.5% to 5,533 as 'Hawkish Hold' Collides With AI Profitability Debate
South Korea's KOSPI index dropped 3.5% to 5,533.77 on October 22, as the Bank of Korea held interest rates steady but left the door open for future hikes. Samsung Electronics and SK Hynix, major semiconductor stocks, fell 4.03% and 5.80% respectively, amid concerns over AI profitability and Meta's financial results. The decline was also influenced by geopolitical risks and reduced corporate buying.
