The U.S. gross national debt officially surpassed the historic $40 trillion milestone, coinciding with intense bond market turbulence as 10-year Treasury yields climbed above 5.25%—their highest levels in nearly two decades. Late-night trading sessions saw heightened volatility following escalating federal interest payments, which now exceed $1 trillion annually. Persistent inflationary pressures, massive budget deficits, and shifting Federal Reserve policy expectations have compounded investor anxiety. Although a brief bond yield reprieve offered temporary calm, broader long-term debt sustainability concerns remain front and center for economists, policymakers, and global financial markets.
