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 fiscal milestone. According to U.S. Treasury’s Debt to the Penny data, the debt hit $40.047 trillion on Aug. 18. By Aug. 27, the total had risen to approximately $40.078 trillion. Of this amount, about $32.314 trillion was held by outside investors and institutions, while federal government accounts managed roughly $7.764 trillion.
Reaching 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 was close to $19.5 trillion. Growth in federal debt occurs when government expenditures surpass revenue, prompting Washington to borrow funds to bridge the gap. Pandemic-related spending led to unusually large deficits, and budget shortfalls persisted even after emergency programs concluded. The government primarily finances these deficits through the sale of Treasury securities.
According to the Congressional Budget Office, the federal budget deficit during the first 10 months of fiscal 2026 totaled $1.8 trillion. This figure is $169 billion higher than the same period a year earlier. Revenues increased by $139 billion, or 3%, while expenditures grew by $308 billion, or 5%. The CBO now projects a $2.1 trillion deficit for fiscal 2026, up from its February estimate of $1.9 trillion.
Interest expenses escalate alongside federal borrowing
Interest payments have become a significant component of federal spending as both debt levels and borrowing costs have surged. Current forecasts indicate net federal interest payments will surpass $1 trillion in fiscal 2026, compared to $970 billion in 2025. This amount represents roughly 3.3% of gross domestic product. By 2036, projections show net interest costs reaching $2.1 trillion, or 4.6% of GDP. At that stage, interest expenses nearly match all projected discretionary federal spending.
The amount of debt held by the public is also close to historic highs relative to the U.S. economy’s size. Projections estimate that this debt will be 101% of GDP in 2026 and will increase to 120% by 2036. The previous record was 106% in 1946, shortly after World War II. The baseline forecasts place publicly held debt at about $56 trillion and gross federal debt near $64 trillion by 2036. The federal debt limit currently stands at $41.1 trillion.
Broader economic impact of rising federal debt
Federal borrowing influences economic conditions beyond government finances. Budget analysts have identified that increased government borrowing competes with private sector borrowing for available savings, leading to higher borrowing costs over time. This process tends to reduce private investment and slow economic growth compared to a lower-debt trajectory. Such reduced investment results in less productive capital for workers, which hampers productivity and wages. These dynamics link federal debt levels with credit conditions, business investment, and household income across the economy.
While gross national debt and the federal deficit reflect different aspects of government finances, both indicators remain high in 2026. Gross debt exceeds $40 trillion, and the annual deficit is estimated at $2.1 trillion. In 2026, federal deficits account for approximately 5.8% of GDP, compared to the long-term average of 3.8% over the past 50 years.
