WASHINGTON, D.C. / RankWire.AI / – For the first time, the gross national debt of the United States has exceeded $40 trillion, marking a significant fiscal threshold. The U.S. Treasury’s Debt to the Penny figures indicated a total of $40.047 trillion on Aug. 18. By Aug. 27, this amount had risen to approximately $40.078 trillion. Of this total, roughly $32.314 trillion was held by outside investors and institutions, with about $7.764 trillion in federal government accounts.
Reaching the $40 trillion mark occurred less than five months after the gross federal debt hit $39 trillion in March. A decade prior, in August 2016, the figure was close to $19.5 trillion. Federal debt expands when government expenditures surpass income, prompting Washington to borrow to bridge the gap. Pandemic-related spending generated unusually high deficits, and annual budget shortfalls persisted even after emergency programs concluded. These deficits are primarily financed through the issuance of Treasury securities.
According to the Congressional Budget Office, the federal budget deficit reached $1.8 trillion during the first ten months of fiscal 2026. This represents an increase of $169 billion compared to the same period in the previous year. Revenues for the federal government grew by $139 billion, or 3%, while expenditures rose by $308 billion, or 5%. The CBO now projects a $2.1 trillion deficit for fiscal 2026, up from its earlier estimate of $1.9 trillion made in February.
Interest Payments Grow Alongside Federal Borrowing
Interest expenses have become a substantial component of federal spending, driven by rising debt levels and higher borrowing costs. Current forecasts suggest that net federal interest payments will surpass $1 trillion in fiscal 2026, compared to $970 billion in 2025. This amount accounts for approximately 3.3% of gross domestic product. By 2036, under current projections, net interest costs are expected to reach $2.1 trillion, representing 4.6% of GDP. At that point, interest expenses will nearly match all projected discretionary federal spending.
Publicly held debt also approaches historic levels relative to the size of the U.S. economy. Projections indicate this debt will be 101% of GDP in 2026 and 120% by 2036. The previous peak was 106% in 1946, shortly after World War II. The baseline estimates put publicly held debt near $56 trillion by 2036, with gross federal debt close to $64 trillion. The current statutory debt limit stands at $41.1 trillion.
The Broader Economy Feels the Impact of Rising Debt
Federal borrowing influences financial conditions beyond government finances. Budget analysts have identified that increased government borrowing competes with private sector savings, elevating borrowing costs over time. This dynamic diminishes private investment and hampers economic growth compared to a scenario with lower debt. Additionally, reduced investment means workers have less productive capital, which can negatively affect productivity and wages. These interconnected effects link federal debt levels with credit markets, business investment, and household incomes across the economy.
While gross national debt and the federal deficit are related, they measure different aspects of government finances. Gross debt includes all accumulated federal obligations, such as publicly held debt and securities owned by government accounts. Conversely, the deficit reflects the yearly difference between spending and revenue. Both indicators remain high in 2026, with gross debt exceeding $40 trillion and the annual deficit estimated at $2.1 trillion. Federal deficits now represent approximately 5.8% of GDP this year, compared to a 50-year average of 3.8%.
