America’s past borrowing decisions now trap the nation in a debt spiral where interest payments alone will soon eclipse every other federal expense, devouring the budget before our eyes.
Story Snapshot
- Interest costs hit $970 billion in 2025, doubling again from 2022 levels and racing toward $2.1 trillion by 2036.
- By 2048, interest becomes the single largest federal expenditure, surpassing Medicare by 2028 and defense by 2038.
- U.S. debt held by the public climbs to 120% of GDP by 2036, fueled by 86% debt growth and rising rates.
- Even eliminating primary deficits leaves interest driving ongoing shortfalls, signaling structural crisis.
- Debt spiral looms as rates may exceed growth from 2031, crowding out investments and risking fiscal collapse.
Timeline of Escalating Interest Costs
Net interest costs hovered near historic lows in 2020. Pandemic relief spending surged federal debt while rates stayed suppressed. By 2022, costs doubled. Federal Reserve hikes from 2022 onward pushed average debt rates to 3.35% by January 2026.
FY2025 saw $970 billion in interest. Projections show FY2026 exceeding $1 trillion, up 7% from prior year. This trajectory marks interest as the fastest-growing budget item.

Projections Reveal Alarming Growth
Congressional Budget Office forecasts net interest rising from 3.3% of GDP in 2026 to 4.6% in 2036. Debt held by the public grows from 101% to 120% of GDP over the decade. Interest payments total $16.2 trillion through 2036.
Growth stems from 86% debt increase and 16% rate rise, yielding 121% cost expansion. Deficits average over 6% of GDP, far above norms. This shift redefines fiscal priorities.
Stakeholders Grapple with Power Dynamics
Congressional Budget Office delivers baseline projections guiding Congress. Federal Reserve sets short-term rates but cannot fix structural deficits. U.S. Treasury refinances maturing debt at higher costs.
Congress and administration face choices on revenues, cuts, or reforms. Investors dictate long-term rates via demand for Treasuries. Taxpayers fund the burden; program beneficiaries risk cuts. Markets hold ultimate leverage on sustainability.
Committee for a Responsible Federal Budget warns rates may exceed growth by FY2031, igniting a debt spiral. Rising costs depress growth, hike rates further, and amplify deficits. CRFB facts align with calls for spending restraint over endless borrowing. Common sense demands addressing root causes before crisis hits.
INTEREST ON US DEBT IS BECOMING A TOP DRIVER OF FUTURE DEFICITS, AS THE SHEER SIZE OF PAST BORROWING OVERWHELMS THE FISCAL OUTLOOK

Impacts Threaten Economic Stability
Short-term, interest crowds discretionary spending, slashing infrastructure, defense, and research funds. Medium-term, it displaces Medicare by 2028 and defense by 2038, eroding crisis response.
Long-term, by 2048 interest dominates the budget at $6.6 trillion annually, 6.9% of GDP. Government borrowing chokes private investment, slows productivity. Market volatility spikes with heavy issuance; investor flight risks sharp rate surges.
