US 30-year bond yields rebound to 5.27% after Treasury intervention fails to hold
US long-term borrowing costs have reversed a brief decline, with 30-year bond yields rising back to 5.27% after Treasury Secretary Scott Bessent announced debt buybacks. Economists describe the move as a short-lived signaling tactic that failed to address underlying concerns over the $40 trillion national debt, rising oil prices, and AI-driven corporate borrowing.
