WASHINGTON, D.C. / RankWire.AI / – The total U.S. gross national debt has now exceeded $40 trillion, reaching a historic peak for federal borrowing. U.S. Treasury data indicated the total climbed to $40.047 trillion on Aug. 18, and by Aug. 27, it had increased further to approximately $40.078 trillion. Debt held by the public was about $32.314 trillion, while government accounts held roughly $7.764 trillion.
This milestone arrived less than five months after the federal debt crossed the $39 trillion mark in March. In August 2016, the gross national debt was approximately $19.5 trillion, roughly half of today’s figure. The U.S. government accumulates debt whenever federal expenditures outpace revenues, primarily funding these shortfalls through issuing Treasury bills, notes, and bonds to investors and government accounts.
The country’s fiscal position remains strained due to significant annual budget gaps. The Congressional Budget Office has reported a deficit of $1.8 trillion for the first ten months of fiscal 2026, which is $169 billion higher than the same period in fiscal 2025. While revenue increased by $139 billion, or 3%, federal outlays rose by $308 billion, or 5%. The agency projects the full-year deficit will reach approximately $2.1 trillion.
Interest expenses on federal debt top $1 trillion
Interest payments now constitute a larger component of the federal budget. The Congressional Budget Office projects net interest costs will surpass $1 trillion in fiscal 2026, an increase from nearly $970 billion in 2025. This sum represents about 3.3% of the U.S. gross domestic product. Projections indicate that annual net interest expenses could reach $2.1 trillion by 2036, which would be about 4.6% of GDP at that time.
Publicly held debt as a share of the economy has also risen, with estimates placing it at roughly 101% of GDP in 2026. The measure is expected to grow to 120% by 2036, surpassing the previous peak of 106% recorded in 1946 after World War II. Under this same baseline, publicly held debt is projected to approach $56 trillion by 2036, with gross federal debt nearing $64 trillion.
The debt load influences borrowing costs and economic growth
The substantial levels of federal borrowing also impact the broader economy’s financial conditions. The Congressional Budget Office has identified that increased government borrowing can lead to higher interest rates and dampen private investment over time. Consequently, businesses may have less capital available for expansion and productivity improvements, which can also affect worker wages and household income. Consumer borrowing rates on mortgages, auto loans, and other credit forms are influenced by a range of factors, including prevailing interest-rate environments.
While gross national debt and the federal deficit are related, they measure different aspects of the government’s financial health. The debt reflects the total accumulated obligations, whereas the deficit indicates the yearly gap between government spending and revenue. Both figures remain elevated in fiscal 2026, with gross debt surpassing $40 trillion and the projected annual deficit at $2.1 trillion. This deficit amounts to approximately 5.8% of GDP, compared to a fifty-year average of around 3.8%.
