U.S. Treasury yields surged Tuesday, with the 30-year yield reaching 5.321%, its highest level since June 2007, as investors weighed inflation, government borrowing and escalating Middle East tensions. The 10-year yield rose to 4.7259%, according to Reuters market data. Brent crude traded around $91 a barrel after U.S.-Iran ceasefire negotiations stalled, raising concern that prolonged conflict could keep energy prices elevated and complicate the Federal Reserve’s inflation fight. Global bond markets weakened, while U.S. stocks faced pressure from higher discount rates overall today. The supplied report’s Monday equity figures are accurate but were dated incorrectly: the S&P 500 closed Monday at 7,745.06, the Dow at 53,459.78 and the Nasdaq at 26,644.91, according to AP. A $25 billion 30-year Treasury auction last week produced a 5.216% yield, the highest auction yield since 2001. Analysts warn that persistent inflation, fiscal deficits and heavy debt issuance could sustain pressure on long-term borrowing costs.
