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 the U.S. Treasury’s Debt to the Penny figures, the debt reached $40.047 trillion on August 18, and by August 27, it had climbed slightly to approximately $40.078 trillion. Of this total, about $32.314 trillion was held by outside investors and institutions, while federal government accounts owned roughly $7.764 trillion.
This crossing of 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 stood at nearly $19.5 trillion. The growth of federal debt results from government spending outpacing revenue, prompting Washington to borrow to bridge the gap. The unusually large deficits during the pandemic era were driven by extraordinary spending measures, and despite the end of emergency programs, annual budget shortfalls have persisted. The government primarily finances these deficits through the issuance of Treasury securities.
In the first ten months of fiscal year 2026, the Congressional Budget Office reported that the federal budget deficit reached $1.8 trillion, which is $169 billion higher than the same period last year. During this period, federal revenues increased by $139 billion, or 3%, whereas outlays rose by $308 billion, or 5%. The agency’s latest estimate projects a $2.1 trillion deficit for fiscal 2026, an increase from its February projection of $1.9 trillion.
Interest Expenses Grow as Federal Debt Expands
The rising levels of debt and associated financing costs have made interest payments a significant component of federal spending. Current forecasts suggest that net federal interest payments will exceed $1 trillion in fiscal 2026, up from $970 billion in 2025, representing roughly 3.3% of gross domestic product. Looking ahead to 2036, estimates indicate that net interest spending will reach $2.1 trillion, or 4.6% of GDP. At this rate, interest costs will nearly match all projected discretionary federal expenditures.
When measured against the size of the economy, debt held by the public is also near historic highs. Projections place this debt at 101% of GDP in 2026 and 120% by 2036, with the previous record being 106% in 1946, shortly after World War II. The baseline scenario anticipates publicly held debt to be close to $56 trillion by 2036, with gross federal debt nearing $64 trillion. Currently, the statutory federal debt limit is set at $41.1 trillion.
Wider Economy Feels the Impact of Rising Federal Debt
The implications of increased federal borrowing extend beyond the government’s balance sheet, influencing broader financial conditions in the economy. Budget analysts have observed that higher government borrowing competes with private sector borrowers for available savings, leading to increased borrowing costs over time. This dynamic tends to reduce private investment, dampen economic growth, and ultimately leave workers with less productive capital, which negatively affects productivity and wages. Such interconnected effects link federal debt levels to credit markets, business investment, and household income throughout the economy.
While gross national debt and the federal deficit are related measures, they focus on different aspects of government finances. Gross debt encompasses total accumulated obligations, including publicly held debt and securities held by government accounts, whereas the deficit reflects the yearly gap between government spending and revenue. Both metrics remain elevated in 2026, with gross debt surpassing $40 trillion and the annual deficit projected at $2.1 trillion. In percentage terms, federal deficits are expected to account for roughly 5.8% of GDP this year, compared to a fifty-year average of 3.8%.
