US national debt recently surpassed $35.7 trillion, with Treasury Department daily statements showing consistent month-over-month increases fueled by annual deficits topping $1.8 trillion, largely from mandatory spending, interest payments exceeding defense outlays, and supplemental appropriations for disasters like Hurricanes Helene and Milton. The Congressional Budget Office's June 2024 long-term outlook projects public debt rising to 116% of GDP by 2034 absent fiscal reforms, implying no peak before 2027 under baseline scenarios. Treasury invoked extraordinary measures in mid-September 2024 after the debt limit suspension expired, setting up a January 2, 2025, deadline that could trigger debt ceiling negotiations, potential government shutdown risks, or further borrowing authority amid post-election lame-duck session dynamics and FY2026 budget debates. Trader consensus reflects entrenched upward trajectory barring recession or major entitlement reforms.
