US National Debt Crosses $40 Trillion for the First Time

US gross national debt surpassed $40 trillion for the first time, reaching $40.047 trillion on August 18, 2026, per Treasury Department data. Decades of borrowing — funding social safety-net programs, military spending, and Trump-era tax cuts — drove the accumulation. The debt ceiling is suspended through January 2027, so no immediate legislative cliff follows, but interest costs are nearing $1 trillion annually.
