The US national debt recently surpassed $39 trillion in March 2026, driven by a $1.9 trillion federal budget deficit projected for fiscal year 2026 by the Congressional Budget Office's February outlook, with deficits expected to widen to $3.1 trillion by 2036 and debt rising to 120 percent of GDP. Persistent structural pressures from mandatory spending on Social Security, Medicare, and surging net interest costs—now exceeding $1 trillion annually—fuel ongoing accumulation, outpacing economic growth as noted by Fed Chair Jerome Powell. No major fiscal reforms or spending cuts have materialized recently, including a failed House push for a Balanced Budget Amendment. Traders eye FY2027 budget negotiations and potential debt ceiling deadlines amid extraordinary measures, though CBO baselines show no peak before 2027 under current law.
