US federal debt crosses 40 trillion dollars following treasury issuance

Treasury data and debt composition

The United States federal debt surpassed 40 trillion dollars for the first time following a new securities issuance on Tuesday, 18 August 2026. Official accounting released by the US Department of the Treasury on Wednesday set total debt at 40.047 trillion dollars. The figure comprises 32.266 trillion dollars in debt held by the public alongside 7.782 trillion dollars in intragovernmental holdings. Total federal debt now represents approximately 125% of gross domestic product, while debt held by the public stands at roughly 101% of GDP. According to Federal Reserve data, US public debt stood at just over 64% of GDP during the global financial crisis.

The forty trillion dollar debt does not just exist on the government's accounting books; it is felt throughout the whole economy and ends up, in one way or another, in citizens' wallets.

Acceleration ahead of official forecasts

The federal debt has doubled in under a decade, rising from 19.95 trillion dollars when Donald Trump was first inaugurated in January 2017. Approximately one-third of that increase occurred during two years of federal borrowing for COVID-19 pandemic relief under Trump and former President Joe Biden. Over the past five months alone, federal obligations climbed by approximately 1 trillion dollars. The crossing arrives roughly two years faster than official estimates projected in May 2023, when the Congressional Budget Office anticipated reaching 40 trillion dollars in 2028. Prior baseline projections from the agency had also estimated that total debt would reach 39.4 trillion dollars by the end of 2026.

With the current trajectory, we will reach 50 trillion dollars in just six years.

Structural deficits and demographic drivers

The United States has not recorded a balanced federal budget since the early 2000s. Over the last four years, the annual federal deficit fluctuated between 5.2% and 6.2% of GDP, following a peak of roughly 15% in 2020 during the pandemic. In the first ten months of the current fiscal year, the deficit reached 1.8 trillion dollars. Demographic shifts maintain sustained spending demands, as roughly 10,000 Baby Boomers retire every day with increased longevity, expanding outlays for Social Security and Medicare without an equivalent growth in the contributing workforce. On the revenue side, successive tax reductions, including the 2017 tax cuts and the One Big Beautiful Bill Act of 2025, constrained collections, while a February Supreme Court decision invalidating federal tariffs required substantial refunds to private companies.

This grim milestone is a reminder that it is time to address a fundamental mismatch.

Escalating interest outlays and Treasury response

Rising debt issuance coincided with borrowing costs returning to levels unseen since the financial crisis. Annual net interest payments are expected to exceed 1 trillion dollars this year, having more than tripled over a five-year span. Federal interest payments now nearly match total spending on Medicare and exceed all funding for national defense. Following a 25 billion dollar auction of 30-year bonds that yielded the highest rate since 2021, long-term bond yields reached near two-decade highs, and the 10-year term premium rose to a 12-year peak. With foreign creditors holding nearly 33% of US sovereign debt, US Treasury Secretary Scott Bessent announced that the Treasury would double buybacks of 10-year to 30-year bonds to at least 4 billion dollars per operation to ease upward pressure on yields.
