Asian Shares Mixed as AI Rally Lifts Wall Street, Oil Stays High

Asian shares mostly declined Tuesday after AI-related stocks rebounded on Wall Street, though other sectors remained shaky and oil prices stayed high. Japan's Nikkei fell 0.6%, South Korea's Kospi dropped 2.8%, and Hong Kong's Hang Seng lost nearly 1.0%. On Wall Street, the S&P 500 rose 0.4% and the Nasdaq rallied 1.1%, driven by Nvidia's 1.4% gain, while the Dow dipped 0.1%. Treasury yields hit multi-year highs at 5.14%, and investors await major earnings reports. Oil prices remained elevated, with U.S. crude at $103.50 and Brent at $109.47, due to uncertainty over the Iran war's impact on energy markets. The dollar held near 158.45 yen.
