WASHINGTON, D.C. / RankWire.AI / – The total gross national debt of the United States has now 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 stood at $40.047 trillion as of August 18. By August 27, this figure had increased slightly to approximately $40.078 trillion. Of this total, about $32.314 trillion was held by external investors and financial institutions, while roughly $7.764 trillion was owed by federal government accounts.
Reaching the $40 trillion threshold occurred less than five months after the federal gross debt hit $39 trillion in March. A decade earlier, in August 2016, the total debt was close to $19.5 trillion. Federal debt expands when government expenditures outpace revenues, necessitating borrowing to bridge the gap. The surge in pandemic-related spending caused unusually high deficits, and although emergency programs ended, annual shortfalls persisted. The government predominantly finances these deficits through the issuance of Treasury securities.
During the first ten months of fiscal year 2026, the Congressional Budget Office reported that the federal budget deficit reached $1.8 trillion. This amount is $169 billion higher than the same period in the previous year. While federal revenues increased by $139 billion, or 3%, total outlays grew by $308 billion, or 5%. The CBO now projects a deficit of $2.1 trillion for the full fiscal year 2026, up from its earlier estimate of $1.9 trillion made in February.
Rising Interest Expenses Reflect Growing Borrowing Costs
Interest payments have become a significant component of federal spending, driven by increasing debt levels and higher financing costs. Current estimates indicate that net federal interest expenditures will surpass $1 trillion in fiscal 2026, compared with $970 billion in 2025. This expenditure accounts for approximately 3.3% of gross domestic product. Under current projections, by 2036, net interest costs could reach $2.1 trillion, or 4.6% of GDP. At that level, interest payments will nearly match all projected discretionary federal spending, highlighting the escalating financial burden.
The debt held by the public is also approaching historic levels relative to the size of the U.S. economy. Experts estimate that this debt will be 101% of GDP in 2026 and rise to 120% by 2036. The record for publicly held debt as a percentage of GDP was 106% in 1946, shortly after World War II. The baseline forecast suggests that by 2036, publicly held debt could total around $56 trillion, with gross federal debt nearing $64 trillion. Currently, the statutory federal debt limit is set at $41.1 trillion.
Wider Economic Impact of Rising Federal Debt
The increasing federal borrowing influences broader financial conditions beyond government accounts. Budget analysts have identified that higher levels of government debt compete with private sector borrowers for available savings, which can raise borrowing costs over time. This competition tends to reduce private investment, leading to slower economic growth compared to a lower-debt scenario. Reduced investment also means less productive capital for workers, which can negatively impact productivity and wages. These interconnected effects tie federal debt levels to 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 finances. Gross debt encompasses accumulated obligations, including publicly held debt and securities held within government accounts. The deficit, on the other hand, reflects the annual difference between government spending and revenue. Both metrics remain elevated in 2026, with gross debt exceeding $40 trillion and the annual deficit projected at $2.1 trillion. This year’s federal deficits constitute about 5.8% of GDP, compared to a 50-year average of 3.8%.
