Tech sell-off hits Asian markets as South Korea and Japan stocks plunge

Global shares mostly declined Thursday, led by sharp drops in Asia, as a technology sell-off deepened after U.S. stocks fell on hotter-than-expected inflation data. South Korea's Kospi lost 7.6% and Japan's Nikkei 225 tumbled 4.9%. Major chipmakers drove the losses, with Samsung Electronics sliding 9.5%, SK Hynix plunging 11.1%, and SoftBank Group losing 9.3%. The declines followed a U.S. report showing consumer prices rose 3.7% year-on-year in September, exceeding forecasts, while Nvidia and AMD fell on Wall Street. European markets were mixed, with Britain's FTSE 100 rising on unexpected August growth. Oil prices dropped 2% to $103.93 per barrel, though still elevated from pre-war levels, and the 10-year U.S. Treasury yield eased to 5.09% after recent spikes.
