Publicly held U.S. debt could reach 222% of GDP by 2056 in a higher-rate scenario

Fortune reports that Treasury yields have surged to their highest levels in two decades. It describes a scenario in which interest rates rise by 1 percentage point and publicly held U.S. debt reaches 222% of GDP by 2056. In that scenario, the increase in debt relative to GDP would push Treasury interest rates beyond the initial rise assumed in the scenario.
