Weiss Ratings warns U.S. debt fight could lift borrowing costs as 2027 ceiling nears
Debt ceiling risks 2027

With a new Congress set to be chosen on Tuesday, investors in Treasuries and bond funds are facing a renewed political clash over federal borrowing rather than any question over whether U.S. debt will be repaid. Weiss Ratings argues the stakes are higher this time because total federal debt has climbed to $40.6 trillion and the borrowing limit of $41.4 trillion could be reached by the middle of 2027.

Highlights

  • Weiss Ratings warns that the 2027 federal debt ceiling vote, with uncertain House control, could complicate negotiations and test cross-party cooperation.
  • Weiss maintains its C- rating for U.S. sovereign debt as federal debt climbs from $14.3 trillion (2011) to $40.6 trillion, with net interest surpassing $1 trillion for fiscal year ended Sept. 30.
  • Weiss states that rising debt and a possible 2027 debt-ceiling impasse could drive investors to demand higher yields, regardless of sovereign credit rating actions.

Debt ceiling timeline and rating warning

As reported by Weiss Ratings, the approaching congressional vote could reshape the negotiations over the federal debt ceiling, especially if control of the House changes and lawmakers need cross-party support to raise the borrowing limit. The firm says that setup makes the debt ceiling one of the first major tests for the next Congress, whichever party controls each chamber.

Weiss said it first urged Standard & Poor's, Moody's and Fitch in May 2010 to downgrade U.S. sovereign debt, then assigned the United States its own C rating in April 2011 and cut that to C- in July of that year. The firm notes that S&P later downgraded the U.S. to AA+ in August 2011, Fitch followed in August 2023 and Moody's acted in May 2025, while Weiss says its own C- assessment remains unchanged.

According to the analysis, federal debt has risen from $14.3 trillion when Weiss first rated the country to $40.6 trillion now, while net interest on that debt topped $1 trillion in the fiscal year ended Sept. 30. Weiss argues that even if a downgrade does not automatically trigger higher borrowing costs, the growing debt load and a potential debt-ceiling standoff in 2027 could reinforce investor demands for higher yields.

In our earlier article on surging long-term Treasury yields and a widening U.S. deficit, we explained how borrowing costs above 5% are feeding into mortgage rates, federal interest expenses, and tighter financial conditions. We also noted that with political gridlock likely after the midterms and total U.S. debt near $40 trillion, prospects for meaningful deficit reduction remain limited even as higher rates threaten to add trillions to future deficits.
