Treasury yields have climbed to levels not seen in years, with some maturities approaching 5%, sharply increasing the cost of servicing U.S. government debt, according to MarketWatch. The rising yields worsen the fiscal outlook the longer they persist, adding pressure to an already strained federal budget. Billionaire investor David Rubenstein warned that America's ballooning debt load is a 'ticking time bomb,' according to Yahoo Finance, echoing concerns about the sustainability of rising Treasury yields and their impact on debt-servicing costs. His comments add a prominent voice from the private-equity world to growing worries about long-term fiscal stability as borrowing costs remain elevated.
