WASHINGTON, D.C. / RankWire.AI / – The total gross national debt of the United States has exceeded the $40 trillion mark for the first time, marking a significant milestone in the country’s fiscal trajectory. Data from the U.S. Treasury’s Debt to the Penny indicated a figure of $40.047 trillion as of August 18. By August 27, this total had increased to approximately $40.078 trillion. Of this amount, roughly $32.314 trillion was held by outside investors and institutions, while the federal government accounts managed about $7.764 trillion.

The crossing of the $40 trillion threshold occurred less than five months after the gross federal debt reached $39 trillion in March. A decade earlier, in August 2016, the total debt was close to $19.5 trillion. The growth in federal debt results from government expenditures that surpass revenue, leading Washington to borrow funds to cover the deficit. Exceptional pandemic-related spending created unusually large deficits, and despite the end of emergency programs, annual budget shortfalls have persisted. The primary method the government uses to finance these deficits is through the sale of Treasury securities.
In the first ten months of fiscal 2026, the Congressional Budget Office reported that the federal budget deficit totaled $1.8 trillion. This figure is $169 billion higher than the same period in the previous year. Federal revenue increased by $139 billion, or 3%, while expenditures rose by $308 billion, or 5%. The agency now projects a deficit of $2.1 trillion for fiscal 2026, up from its earlier estimate of $1.9 trillion made in February.
Interest Payments Expand as Federal Borrowing Grows
Interest expenses have become a substantial component of federal spending, driven by rising debt levels and increasing financing costs. Current forecasts indicate net federal interest payments will surpass $1 trillion in fiscal 2026, compared to $970 billion in 2025. This amount represents approximately 3.3% of the gross domestic product. Looking ahead to 2036, projections estimate net interest costs will reach $2.1 trillion, or 4.6% of GDP. At this level, interest expenses will nearly match all projected discretionary federal spending.
The amount of debt held by the public remains near historic highs relative to the size of the U.S. economy. Forecasts suggest that public debt will be 101% of GDP in 2026 and rise to 120% by 2036. The previous record was 106% in 1946, shortly after World War II. These projections estimate that publicly held debt will approach $56 trillion by 2036, with gross federal debt nearing $64 trillion. The federal debt limit set by law is currently $41.1 trillion.
Broader Economic Impact of Growing Federal Debt
Government borrowing impacts broader financial conditions beyond federal finances. Budget analysts have found that increased government borrowing competes with private sector savings, pushing up borrowing costs over time. This dynamic can diminish private investment and slow economic growth compared to a scenario with lower debt levels. Additionally, reduced private investment limits productive capital for workers, which can hinder productivity and wages. These interconnected effects link the level of federal debt with credit market conditions, business investment, and household income across the economy.
While gross national debt and the federal deficit are different measures, both remain elevated in 2026. Gross debt has surpassed $40 trillion, and the annual deficit is estimated at $2.1 trillion. This year, federal deficits account for roughly 5.8% of GDP, well above the 50-year average of 3.8%.
