The Treasury reported total public debt above $40 trillion after a one-day jump of over $60 billion. Rising yields, surging interest costs and new Treasury actions to support long-term securities are central to the story.
U.S. public debt surpassed $40 trillion following a one-day increase of more than $60 billion and a $1 trillion rise in just over three months.
The Treasury announced larger liquidity-support buybacks for longer-dated nominal coupon securities, a move that pushed yields down short term.
Higher borrowing costs create a feedback loop: higher yields raise interest expense, which adds to debt and can force borrowing at still-higher yields — described in the article as a “doom loop.”
Headline: "Doom Loop" Engaged: U.S. Debt Hits $40 Trillion As Treasury Enters The Endgame
The Treasury reported total public debt crossed $40 trillion after a single-day increase of over $60 billion. The article notes the debt has climbed by $1 trillion in just over three months and rose by roughly one-third in less than five years. For context, U.S. debt reached $30 trillion in January 2022.
Treasury Secretary Scott Bessent announced an unexpected change to issuance policy aimed at lowering long-term borrowing costs. The department said it will at least double the size of liquidity-support buyback operations for longer-dated nominal coupon securities in the 10–20, 20–30 year sectors. That announcement pushed yields lower immediately, and it came only two weeks after the latest Refunding Announcement when such a change normally would have been made.
With two months left in the fiscal year covered by the piece, interest costs for 2026 were $1.37 trillion, about 20% higher than the same period a year earlier. The Treasury made record-setting coupon payments, including an $85 billion semiannual payout. Interest spending has become the third-largest budget item, surpassing healthcare and sitting just behind Social Security. The article projects gross interest could top Social Security around 2026.
Broader pressures: AI investment and market demand
The article highlights a surge in private-sector borrowing tied to AI-related capital expenditure. It claims record issuance to fund corporate capex is crowding out demand for U.S. Treasuries, forcing higher yields. That dynamic raises a policy choice: prioritize popular domestic spending or finance large tech investments. The article adds that rising memory and semiconductor costs tied to AI development are contributing about 0.5% to core PCE, a politically sensitive inflation component.
The story lays out a short-term Treasury intervention to lower long-term yields and a longer-term fiscal concern: growing interest costs that increase the debt burden and can feed higher yields, creating a reinforcing cycle the article calls a "doom loop."
The U.S. deficit has reached $1.97 trillion and is on track to pass 6% of gross domestic product this fiscal year, the latest milestone in a remarkable deterioration of the federal budget. With national debt at a record $40 trillion, the feeling that the music must stop at some point has jittery market watchers zeroed
