Asian shares fall, oil climbs as AI earnings loom

Asian stocks fell broadly on Tuesday while oil prices rose, as geopolitical tensions and anticipation of key AI sector earnings weighed on investor sentiment. The dollar held firm against the euro amid riots in France, which boosted demand for safe-haven assets. Crude prices climbed after a US executive order waived some sanctions and tariffs on Russian energy, while investors awaited results from Meta, Tesla, and chipmakers Lam Research and Texas Instruments. The MSCI Asia ex-Japan index dropped 0.93 percent, and South Korea's KOSPI tumbled 3.61 percent. French authorities set curfews in several cities following weekend riots, and Federal Reserve officials signaled no rush to hike rates again. Brent crude rose to $109.78 a barrel, while spot gold fell to $4,118.71 an ounce.
