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 milestone in the country’s fiscal history. According to U.S. Treasury’s Debt to the Penny data, the debt reached $40.047 trillion on August 18. By August 27, this figure had increased slightly to approximately $40.078 trillion. Of that total, roughly $32.314 trillion was held by outside investors and institutions, while about $7.764 trillion was held in 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 debt was near $19.5 trillion. The growth of federal debt results from government expenditures outpacing revenue, prompting Washington to borrow funds to bridge the gap. Pandemic-related spending generated unusually large deficits, and annual budget shortfalls persisted even after emergency programs concluded. The government primarily finances these deficits through issuing Treasury securities.
The Congressional Budget Office reported in August that the federal budget deficit for the first ten months of fiscal 2026 reached $1.8 trillion. This is $169 billion higher than the deficit during the same period last year. 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 the full fiscal year 2026, revised upward from its February estimate of $1.9 trillion.
Interest expenses climb as borrowing expands
As debt levels and borrowing costs rise, interest payments have become a significant component of federal spending. Current forecasts suggest that net federal interest costs will top $1 trillion in fiscal 2026, up from $970 billion in 2025. This amount represents approximately 3.3% of the gross domestic product. Under current projections, interest payments are expected to reach $2.1 trillion by 2036, or 4.6% of GDP. At that level, interest costs will nearly match all projected discretionary federal spending.
Publicly held debt as a share of the economy is also near historic highs. Forecasts for 2026 suggest it will be 101% of GDP, rising to 120% by 2036. The previous peak was 106% in 1946, just after World War II. The baseline projections estimate that publicly held debt will be around $56 trillion by 2036, with gross federal debt nearing $64 trillion. The current statutory debt ceiling stands at $41.1 trillion.
Debt’s broader economic influence
Federal borrowing impacts the wider economy beyond government finances, affecting credit markets and private sector investment. Analysts have observed that increased government borrowing competes with private borrowers for available savings, which raises borrowing costs over time. This process tends to diminish private investment and hampers economic growth compared to a lower-debt trajectory. Reduced investment can lead to less productive capital for workers, ultimately affecting productivity and wages. These dynamics link federal debt levels with credit availability, business investment, and household income across the economy.
While gross national debt and the federal deficit are related, they measure different aspects of government finance. Gross debt reflects the total accumulated obligations, including publicly held debt and securities held by government accounts. The deficit indicates the annual difference between government spending and revenue. Both figures remain high in 2026, with gross debt exceeding $40 trillion and the annual deficit projected at $2.1 trillion. This year, federal deficits constitute about 5.8% of GDP, compared to a 50-year average of 3.8%.
