WASHINGTON, D.C. / RankWire.AI / – The United States has crossed a historic financial threshold, with its gross national debt exceeding $40 trillion for the first time, marking a significant milestone in fiscal history. According to the U.S. Treasury’s Debt to the Penny data, the debt reached $40.047 trillion on Aug. 18. By Aug. 27, this figure increased to approximately $40.078 trillion. Of this total, around $32.314 trillion was held by outside investors and institutions, while federal government accounts held approximately $7.764 trillion.
The milestone of surpassing $40 trillion occurred less than five months after the federal gross debt hit $39 trillion in March. A decade ago, in August 2016, the total was close to $19.5 trillion. Federal debt expands when government expenditures outpace revenues, leading Washington to borrow to bridge the gap. The pandemic prompted unusually high deficits through extensive spending, which persisted even after emergency programs concluded, leading to ongoing annual budget shortfalls. The government primarily finances these deficits through the issuance of Treasury securities.
During the first ten months of fiscal 2026, the Congressional Budget Office reported a federal budget deficit of $1.8 trillion. This figure is $169 billion higher than the same period last year. Federal revenues increased by $139 billion, or 3%, while outlays grew by $308 billion, or 5%. The CBO now projects a $2.1 trillion deficit for fiscal 2026, up from their February estimate of $1.9 trillion.
Rising interest costs driven by increased borrowing
The escalating debt levels and higher financing costs have made interest payments a major component of federal spending. Current forecasts indicate that net federal interest expenses will surpass $1 trillion in fiscal 2026, up from $970 billion in 2025. This constitutes roughly 3.3% of gross domestic product. Under existing projections, by 2036, net interest spending could reach $2.1 trillion, or 4.6% of GDP. At this level, interest costs are projected to nearly match all discretionary federal spending.
Publicly held debt also approaches historic highs relative to the size of the U.S. economy. Forecasts suggest that this debt will be 101% of GDP in 2026 and increase to 120% by 2036. The previous peak was 106% in 1946, shortly after World War II. The baseline scenario estimates that publicly held debt will be around $56 trillion by 2036, with gross federal debt near $64 trillion. The current statutory debt ceiling stands at $41.1 trillion.
Broader economic impact of rising debt levels
Federal borrowing influences the broader economy by affecting borrowing conditions beyond the government’s finances. Budget analysts have observed that increased government borrowing competes with private sector borrowers for available savings, pushing up borrowing costs over time. This process can hinder private investment and slow economic growth compared to a lower-debt trajectory. Reduced investment also results in less productive capital for workers, impacting productivity and wages. These interconnected effects link federal debt levels to credit conditions, business investment, and household income across the economy.
While gross national debt and the federal deficit are related, they measure different aspects of government finances. Gross debt encompasses all accumulated federal obligations, including publicly held debt and securities held by government accounts. The deficit reflects the yearly difference 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. This year, federal deficits account for about 5.8% of GDP, compared to a 50-year average of 3.8%.
