US National Debt Tops $40 Trillion For The First Time

By World Insight StaffWASHINGTON — Aug. 20, 2026

Total United States government debt surpassed $40 trillion for the first time, the Treasury Department said this week, a milestone that arrived roughly two years earlier than government forecasters had projected and that has coincided with a sharp rise in the government’s own borrowing costs.

Treasury’s daily debt statement, which is released on a one-day lag, showed total public debt outstanding at $40.047 trillion as of Tuesday. The figure is made up of $32.266 trillion in Treasury securities held by outside investors and $7.782 trillion in debt the government owes to its own trust funds and accounts, such as Social Security. The debt has now more than doubled from the $19.95 trillion recorded when President Donald Trump was first sworn in, in January 2017.

The number affects far more than a government ledger. Economists and Treasury officials say the rising debt load feeds into everyday borrowing costs for mortgages, auto loans and credit cards, since Treasury yields serve as a benchmark for private lending rates across the economy. The Committee for a Responsible Federal Budget, a nonpartisan fiscal watchdog, said in a statement that the sum is felt throughout the economy rather than sitting only on government books.

The government has run persistent annual deficits because spending, driven largely by Social Security, Medicare and rising interest payments, has outpaced tax revenue for years under presidents and lawmakers of both parties. The nonpartisan Congressional Budget Office projected in March that this year’s deficit would reach about $2.1 trillion, on its way to roughly $3.1 trillion a year by the mid-2030s. Treasury reported a $432.3 billion deficit for July alone, the fourth-highest monthly total in U.S. history, which officials attributed partly to reduced customs revenue after refunds tied to tariffs the Supreme Court had ruled unlawful.

Political accounts of the increase

The Trump administration has largely attributed the debt’s growth to the previous administration. Treasury Secretary Scott Bessent said in a recent television appearance that the government “inherited a mess,” referring to the fiscal position left by former President Joe Biden, and said the administration was making progress toward paying down the debt. White House spokesman Kush Desai said the administration has been focused on “slashing waste, fraud, and abuse in federal spending” to improve the trajectory of the debt relative to the size of the economy.

Independent analysts and fiscal watchdogs describe a longer, bipartisan pattern instead. Public debt rose $7.8 trillion during Trump’s first term, more than half of it in the final nine months tied to pandemic relief spending. It then rose $8.4 trillion during Biden’s term, driven by continued pandemic recovery spending as well as infrastructure and clean-energy outlays. Since Trump returned to office in January 2025, the debt has grown a further $3.8 trillion, for combined growth of $11.6 trillion across his two terms. House Speaker Mike Johnson has defended Republican-passed legislation, including the tax and spending package known as the One Big Beautiful Bill Act, calling it “a dramatic shift in the right direction,” while the CBO estimates that same law will itself add about $4.7 trillion to the debt over the coming decade.

Interest costs and market strain

The debt milestone landed alongside turbulence in the bond market. The 30-year Treasury yield touched its highest level since 2007 this week, and the 10-year yield neared its highest point of Trump’s second term, as investors demanded higher returns amid inflation concerns tied to the monthslong conflict involving Israel, Iran and the United States, alongside a wave of corporate debt issuance to fund artificial-intelligence infrastructure. Interest payments on the debt have cost the federal government roughly $1.2 trillion so far this year and now exceed spending on national defense, according to Treasury data reported by multiple outlets; in the current fiscal year, interest costs have also surpassed Medicare to become the second-largest line item in the federal budget, behind Social Security.

Treasury said this week it would at least double the size of its debt-buyback operations for bonds maturing in 10 to 30 years, to at least $4 billion per operation from $2 billion, running from Sept. 9 to Nov. 4 and totaling an estimated $128 billion over the year. Treasury described the move as a technical step to support market liquidity; investors and analysts said its practical effect was to ease upward pressure on long-term yields. Longer-dated yields fell sharply after the announcement, with the 30-year yield dropping from about 5.26% to as low as 5.18% and the 10-year slipping from roughly 4.68% to 4.63%. It was the second time this month Bessent has intervened in markets, after the U.S. joined Japan on Aug. 1 in an effort to slow the yen’s decline.

Background

The debt has grown steadily for decades under administrations of both parties, through the tax cuts and wars of the 2000s, the 2008 financial crisis, the 2017 Tax Cuts and Jobs Act, and pandemic-era relief spending starting in 2020. Roughly one-third of the total increase since January 2017 occurred during the two years that followed the declaration of the COVID-19 pandemic in March 2020, when the government under both Trump and Biden borrowed heavily to fund relief programs. The pace has continued to accelerate since: the debt crossed $38 trillion in October 2025 and $39 trillion in March 2026, meaning the most recent trillion dollars accumulated in about five months. As recently as May 2023, the CBO had projected the debt would not reach $40 trillion until fiscal year 2028.

Congress raised the statutory debt ceiling by $5 trillion last year as part of the One Big Beautiful Bill Act, a step lawmakers took with comparatively little public fight compared with past debt-limit battles. That increase means Congress is not expected to have to revisit the borrowing limit until sometime in 2027. Ratings agencies S&P, Fitch and Moody’s have each downgraded U.S. credit since 2011, citing in part the recurring brinkmanship over the debt ceiling.

What follows

The CBO’s most recent projection has the debt climbing to roughly $63 trillion by 2036 if current law remains unchanged, with annual deficits nearly tripling over that period. Fiscal watchdogs, including the Bipartisan Policy Center and the group Concord Action, have called on lawmakers to raise revenue, cut spending or both, warning that neither Congress nor the White House currently has a stated plan to reverse the trend. Separately, the Social Security trust fund is projected to become insolvent in 2032, which would trigger an automatic cut of about 22% to benefits unless Congress acts before then.

It remains unconfirmed whether the Treasury’s expanded bond buybacks will durably lower the government’s borrowing costs or merely offer temporary relief, and analysts disagree on the point. It is also not yet clear whether Congress will attempt to address the debt ceiling during a lame-duck session this winter should control of one or both chambers change hands in the Nov. 3 midterm elections, or wait until the new Congress is seated in January 2027.

Editor’s note on sourcing A separate House budget-resolution deficit estimate for fiscal 2026-2027, reported by a single regional outlet, was excluded because it could not be corroborated against the CBO’s baseline figures used elsewhere in this article. Commentary framing the debt dynamics as a “doom loop,” found on a single opinion-oriented financial site, was excluded as editorializing rather than reporting. The precise durability of this week’s drop in Treasury yields following the buyback announcement remains unconfirmed and is noted as such in the article.
