Asian shares fall as oil prices drop over 1%

Asian shares mostly fell Monday following a Wall Street retreat, while oil prices dropped over 1% after reaching four-year highs last week. U.S. futures edged higher as investors braced for major earnings reports and central bank decisions. Tokyo's Nikkei slipped 0.1%, Seoul's Kospi dropped 1.1%, and Shanghai lost 0.4%, though Hong Kong edged higher. Brent crude fell 1.3% to $110.23 a barrel, and U.S. benchmark crude sank 1.7% to $101.52. Friday's S&P 500 decline marked its second-straight weekly loss. Investors are focused on AI-related companies reporting results this week, including Alphabet, Microsoft, and Amazon, amid concerns over high valuations and borrowing costs. The Federal Reserve is expected to hold rates steady, with inflation running well above its 2% target.
