WASHINGTON, D.C. / RankWire.AI / – As of August 18, the U.S. Treasury reported that the total gross national debt had exceeded $40 trillion, reaching $40.047 trillion. By August 27, this figure increased to approximately $40.078 trillion. Public debt held by the government amounted to about $32.314 trillion, with government-held accounts totaling roughly $7.764 trillion.
This historic milestone occurred less than five months after the debt first crossed the $39 trillion mark in March. In August 2016, the gross national debt was close to $19.5 trillion, roughly half of today’s amount. The government’s borrowing rises when federal expenditures outpace revenue, mainly financed through the issuance of Treasury bills, notes, bonds, and other securities to investors and government accounts.
Remaining under considerable pressure, U.S. finances are challenged by sizeable annual budget deficits. The Congressional Budget Office reported a deficit of $1.8 trillion for the first 10 months of fiscal 2026, which is $169 billion higher than the same period in fiscal 2025. During this period, revenue grew by $139 billion, a 3% increase, while federal outlays surged by $308 billion, or 5%. The CBO projects the total deficit for the entire year to reach approximately $2.1 trillion.
Federal interest payments surpass $1 trillion
Currently, interest costs are occupying a larger portion of the federal budget. For fiscal 2026, net interest expenses are expected to go beyond $1 trillion, an increase from nearly $970 billion in 2025. This amount is approximately 3.3% of the gross domestic product (GDP). Projections indicate that by 2036, annual net interest payments could reach $2.1 trillion, representing around 4.6% of GDP.
The debt held by the public has also risen relative to the size of the U.S. economy. Estimates place this at about 101% of GDP in 2026, climbing to 120% by 2036. The previous peak was 106% in 1946, after World War II. Under the same baseline, publicly held debt could approach $56 trillion by 2036, with gross federal debt nearing $64 trillion.
The debt burden impacts borrowing and economic growth
From late 2026 onward, heavy federal borrowing is expected to influence overall financial conditions. The Congressional Budget Office has found that increased government borrowing can lead to higher interest rates, which may reduce private investment over time. This reduction in capital affects business expansion and productivity improvements, ultimately influencing wages and household income. Consumer loans, such as mortgages and auto loans, are also affected by broader interest rate trends.
While gross national debt and the federal deficit are interconnected, they measure different aspects of the government’s fiscal health. The debt reflects the total accumulated obligations, whereas the deficit indicates the yearly gap between government spending and revenue. Both metrics remain elevated in fiscal 2026, with gross debt surpassing $40 trillion and the annual deficit estimated at $2.1 trillion. This deficit makes up about 5.8% of GDP, significantly higher than the 50-year average of approximately 3.8%.
