Global stocks fell Tuesday as tensions between Russia and the U.S. escalated over nuclear policies. Russia expanded its nuclear doctrine to include retaliation for attacks on Belarus or Russian territory, following U.S. approval for Kyiv's use of American-made long-range missiles. Safe-haven assets rallied, with gold climbing nearly 1% and the Japanese yen rising against the euro and U.S. dollar. Oil prices remained weak, with Brent and WTI futures both declining. Analysts noted short-lived market reactions to similar geopolitical developments, emphasizing a cautious outlook.
