WASHINGTON, D.C. / RankWire.AI / – For the first time, the U.S. gross national debt has exceeded $40 trillion, marking a significant fiscal milestone. The U.S. Treasury’s Debt to the Penny figures indicated $40.047 trillion on Aug. 18. By Aug. 27, the total had increased to approximately $40.078 trillion. Of this amount, about $32.314 trillion was held by outside investors and institutions, while roughly $7.764 trillion was owned by federal government accounts.
Reaching the $40 trillion threshold occurred less than five months after the gross federal debt hit $39 trillion in March. A decade earlier, in August 2016, the total stood close to $19.5 trillion. The growth in federal debt results from government spending outpacing revenue, with Washington borrowing to bridge the gap. The pandemic-era expenditures contributed to unusually large deficits, and the ongoing annual budget shortfalls persisted even after emergency programs concluded. The government primarily finances these deficits through issuing Treasury securities.
In the first 10 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 deficit recorded during the same period last year. Federal revenues increased by $139 billion, or 3%, while outlays grew by $308 billion, or 5%. The agency now projects a $2.1 trillion deficit for fiscal 2026, up from its February estimate of $1.9 trillion.
Rising interest costs are driven by increased federal borrowing
Interest payments have become a significant component of federal expenditure as debt levels and borrowing costs have climbed. Current projections suggest that net federal interest spending will surpass $1 trillion in fiscal 2026, compared to $970 billion in 2025. This amount represents about 3.3% of gross domestic product. Under current estimates, net interest costs are expected to reach $2.1 trillion by 2036, or 4.6% of GDP. At that level, interest expenses will nearly match all projected discretionary federal spending.
Publicly held debt is also approaching historic highs relative to the size of the U.S. economy. The current projections place this debt at 101% of GDP in 2026 and 120% by 2036. The previous record was 106% in 1946, shortly after World War II. The baseline scenario suggests publicly held debt will be around $56 trillion by 2036, with gross federal debt near $64 trillion. The federal debt limit currently stands at $41.1 trillion.
Federal borrowing impacts the broader economy
Beyond the federal budget, increased borrowing influences financing conditions across the economy. Budget analysts have observed that higher government borrowing competes with private sector efforts for available savings, which in turn raises borrowing costs over time. This process can suppress private investment and slow economic growth compared to a lower-debt trajectory. Reduced investment results in less productive capital for workers, negatively affecting productivity and wages. These dynamics link federal debt levels to credit conditions, business investment, and household income nationwide.
Gross national debt and the federal deficit reflect different aspects of the government’s financial health. The gross debt encompasses all accumulated federal obligations, including debt held publicly and securities owned by government accounts. The deficit measures the yearly gap between government spending and revenue. Both indicators remain high in 2026, with gross debt exceeding $40 trillion and the annual deficit estimated at $2.1 trillion. The federal deficits currently account for about 5.8% of GDP, compared with a 50-year average of 3.8%.
