U.S. Treasury yields surged on Tuesday as escalating U.S.-Iran tensions lifted oil prices and revived inflation concerns, pressuring global stocks. Reuters reported the 30-year Treasury yield rose 1.64 basis points to 5.3264%, its highest level in nearly two decades, while the 10-year yield reached 4.7399%. S&P 500 and Nasdaq 100 futures fell 0.54% and 1.05%, respectively, while the VIX climbed to its highest level in more than a week. Brent crude rose 0.3% to $91.14 a barrel as hopes for extending a ceasefire faded. Traders priced a 36.6% probability of a September Federal Reserve rate increase, according to Reuters. The supplied claim that roughly $200 billion in stock-market value disappeared within 30 minutes, attributed to analyst André Dragosch, was not independently established in accessible primary or major reporting. Fed minutes are due Wednesday, with Jackson Hole next week offering further policy signals about the outlook for inflation and interest rates.
