WASHINGTON, D.C. / RankWire.AI / – The total gross national debt of the United States has crossed the $40 trillion mark for the first time, marking a significant milestone in the country’s fiscal history. According to U.S. Treasury’s Debt to the Penny data, the debt stood at $40.047 trillion on August 18. By August 27, this figure had increased to approximately $40.078 trillion. Of this total, about $32.314 trillion was held by outside investors and institutions, while federal government accounts managed roughly $7.764 trillion.
Reaching the $40 trillion level occurred less than five months after the gross federal debt hit $39 trillion in March. A decade prior, in August 2016, the total was close to $19.5 trillion. The growth of federal debt results from government expenditures surpassing revenue, prompting borrowing to bridge the gap. Pandemic-related spending contributed to unusually high deficits, and annual budget shortfalls persisted even after emergency programs concluded. The government primarily finances these deficits through issuing Treasury securities.
According to the Congressional Budget Office, the federal budget deficit reached $1.8 trillion in the first 10 months of fiscal 2026. This is $169 billion more than the same period last year. Revenues increased by $139 billion, or 3%, while outlays 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 in February.
Interest payments escalate alongside federal borrowing
As debt levels and borrowing costs climb, interest payments have become a substantial part of federal expenditure. Current forecasts estimate net federal interest expenses will exceed $1 trillion in fiscal 2026, compared to $970 billion in 2025. This amounts to roughly 3.3% of gross domestic product. By 2036, projections suggest net interest costs will reach $2.1 trillion, or 4.6% of GDP. At this level, interest costs nearly match all projected discretionary federal spending.
Publicly held debt also approaches historic levels relative to the U.S. economy. Estimates place it at 101% of GDP in 2026 and 120% by 2036. The previous record was 106% in 1946, shortly after World War II. The baseline forecast indicates publicly held debt will be around $56 trillion by 2036, with gross federal debt near $64 trillion. Currently, the statutory federal debt limit is set at $41.1 trillion.
Federal debt’s broader impact on the economy
Government borrowing influences financial conditions beyond federal finances, affecting private sector borrowing costs and overall economic activity. Budget analysts find that increased government borrowing competes with private borrowers for available savings, raising borrowing costs over time. This dynamic dampens private investment and hampers economic growth relative to a lower-debt trajectory. Reduced investment also results in less productive capital for workers, negatively affecting productivity and wages. These interconnected effects link federal debt levels to credit conditions, business investments, and household incomes across the broader economy.
While gross national debt and the federal deficit both measure different aspects of the government’s financial health, they are both elevated in 2026. Gross debt exceeds $40 trillion, and the annual deficit is estimated at $2.1 trillion. The federal deficits now amount to about 5.8% of GDP this year, compared to a 50-year average of 3.8%.
