Despite the U.S. 10-year Treasury yield breaking above 5%, sparking concerns that rising borrowing costs could lead to a debt spiral, some bond market experts believe the U.S. is still far from a fiscal crisis, CNBC reported. Analysts at TD Securities and L&G Asset Management point to the long weighted-average maturity of U.S. debt, an average interest rate below nominal economic growth, and the "exorbitant privilege" of the U.S. dollar as buffering factors. They argue that the surge in yields is also linked to economic resilience and expectations of Federal Reserve rate hikes, rather than solely fiscal concerns.
