    U.S. National Debt Crosses $40 Trillion as Annual Interest Reaches $1.25 Trillion

    Question

    U.S. National Debt Crosses $40 Trillion as Annual Interest Reaches $1.25 Trillion

    Direct answer

    The gross national debt of the United States has passed the $40 trillion threshold. Concurrently, annual federal net interest payments reached $1.25 trillion, driven by the compounding effects of elevated debt levels and 5%-plus policy rates. The accelerating cost of debt service increases Treasury refunding requirements across bill and coupon auctions. Market analysts note that structural supply increases require sustained institutional demand to prevent further upward yield drift across the sovereign curve.
