Asian Shares Fall as Wall Street Rally Fades on Rate Concerns

Asian shares and U.S. futures fell Thursday after Wall Street rallied on strong corporate earnings, with Tokyo's Nikkei dropping 1.6% and Seoul's Kospi sliding 2.6% amid heavy selling of tech and AI-related stocks. The declines were led by major chipmakers and equipment firms, including Samsung Electronics down 3.9% and Tokyo Electron falling 5.9%, as investors worry that rising borrowing costs may slow data center construction. U.S. stocks had risen Wednesday, boosted by SpaceX's 7.8% jump and other profit beats. The 10-year Treasury yield held at 5.12%, while oil prices climbed, with Brent crude up 1.6% to $110.55 per barrel amid uncertainty over the Iran war's impact on energy markets. The dollar weakened to 157.69 yen.
