Asian tech sell-off sinks South Korea and Japan markets

Asian shares fell sharply Thursday, with South Korea's Kospi losing 8% and Japan's Nikkei 225 tumbling 5%, as a deepening tech sell-off followed hotter-than-expected U.S. inflation data and Wall Street losses. South Korea's Samsung Electronics slid 9.7% and SK Hynix plunged 11.1%, while Japan's SoftBank Group lost 9.6% and Tokyo Electron dropped 7.5%. Taiwan's Taiex fell 3.4%, and Hong Kong's Hang Seng declined 1.3%. U.S. futures were also lower. The declines stem from September U.S. consumer prices rising 3.7% year-on-year, exceeding forecasts. Surging bond yields, driven by inflation worries from the Iran war and rising U.S. debt, added pressure. Oil prices fell, with Brent crude at $104.47 per barrel, still elevated from pre-war levels.
