Federal watchdog report cites rising borrowing, higher rates, and long-term fiscal risks as Treasury refinances trillions in debt.

The U.S. Government Accountability Office warned that escalating federal debt and sustained higher interest rates could drive annual interest payments on the national debt beyond $1 trillion, highlighting growing fiscal pressure despite continued investor demand for U.S. securities.
In its March 2026 report, the agency said the U.S. Department of the Treasury has so far managed to meet borrowing needs by increasing the scale and frequency of debt auctions, supported by steady participation from domestic and international investors.

“Investor demand for Treasury auctions remains sufficient for Treasury to meet the government’s borrowing needs,” the report states.
The analysis detailed a significant expansion in borrowing activity over the past decade. In fiscal year 2025 alone, Treasury refinanced approximately $9.1 trillion in maturing obligations while issuing an additional $1.9 trillion in new debt to finance the deficit and maintain cash balances.
The report found that rising interest rates combined with the growing debt load are driving borrowing costs sharply higher. Interest payments on debt held by the public approached $1 trillion in fiscal 2025, exceeding $970 billion and surpassing spending levels in major federal categories, including national defense.
“Elevated interest rates combined with large deficits would add to the government’s interest costs, which were larger than $970 billion in fiscal year 2025. These annual interest costs exceeded spending for some of the largest federal programs and areas, including national defense,” the report states.
The GAO cautioned that continued reliance on debt financing could create vulnerabilities if investor demand weakens or if rates rise further, potentially increasing borrowing costs and complicating future debt management.
To mitigate those risks, the watchdog emphasized the importance of maintaining a broad and diversified investor base, including participation from both domestic and foreign buyers as well as a range of financial institutions.
The report also reiterated prior recommendations urging Congress to address long-term fiscal challenges. These include developing a comprehensive strategy to stabilize the nation’s fiscal trajectory and reforming the current debt limit framework to better align borrowing decisions with revenue and spending policies.
“Addressing these risks would help ensure the continued broad-based demand for Treasury securities and support Treasury’s goal of financing the government at the lowest cost over time,” the report states, noting that as of February 2026, lawmakers had not implemented the recommended actions.
The findings underscore mounting concerns over the sustainability of federal debt levels as borrowing continues to rise alongside interest obligations.
