US National Debt Tops $40 Trillion

US gross national debt surpassed $40 trillion for the first time on August 18, 2026, reaching $40.047 trillion, per Treasury data. Decades of borrowing — for safety-net programs, military spending, and Trump-era tax cuts — drove the buildup. The debt ceiling is suspended through January 2027, so no immediate legislative crisis looms, but annual interest costs now approach $1 trillion.
