WASHINGTON, D.C. / RankWire.AI / – The U.S. Treasury’s Debt to the Penny data indicates that the nation’s gross national debt exceeded $40 trillion for the first time, marking a significant fiscal milestone. As of Aug. 18, the total reached $40.047 trillion, and by Aug. 27, it had risen to roughly $40.078 trillion. Of this amount, approximately $32.314 trillion was held by outside investors and institutions, while the federal government’s own accounts held about $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 total was close to $19.5 trillion. Federal debt increases when government expenditures surpass revenues, prompting Washington to borrow to bridge the gap. The extraordinary deficits during the pandemic and ongoing annual shortfalls, even after emergency programs ended, have driven debt growth. These gaps are primarily financed through the issuance of Treasury securities.
The Congressional Budget Office reported in August that the federal budget deficit totaled $1.8 trillion during the first 10 months of fiscal 2026. This figure is $169 billion higher than the same period a year earlier. 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, an increase from its February estimate of $1.9 trillion.
Interest Expenses Climb as Borrowing Expands
Rising debt levels and increasing financing costs have made interest payments a major component of federal expenditure. Current estimates suggest net federal interest spending will surpass $1 trillion in fiscal 2026, up from $970 billion in 2025. This amount accounts for roughly 3.3% of the gross domestic product. Projections for 2036 indicate net interest costs could reach $2.1 trillion, or 4.6% of GDP. At that point, interest expenses would nearly match all projected discretionary federal spending.
When measured against the size of the economy, debt held by the public is also near historic highs. Forecasts place this debt at 101% of GDP in 2026 and 120% by 2036. The previous peak was 106% in 1946, soon after World War II. The baseline scenario projects publicly held debt will be around $56 trillion by 2036, with gross federal debt approaching $64 trillion. Currently, the statutory debt limit is set at $41.1 trillion.
Wider Economic Impact of Rising Federal Debt
Government borrowing influences financial conditions beyond the federal budget, as increased issuance of debt competes with private sector borrowing for available savings and raises overall borrowing costs. This dynamic can hinder private investment and slow economic growth compared to a lower-debt trajectory. Reduced investment also means less productive capital for workers, which affects productivity and wages. These interconnected effects tie federal debt levels to credit markets, business investments, and household income across the economy.
While gross national debt and the federal deficit are different measures of government finance, both remain high in 2026. Gross debt exceeds $40 trillion, and the annual deficit is estimated at $2.1 trillion. Federal deficits are expected to make up about 5.8% of GDP this year, compared to a 50-year average of 3.8%.
