A Historic and Troubling Milestone
For the first time in American history, the national debt of the United States has surpassed $40 trillion, according to data released by the Department of the Treasury. The landmark figure has intensified longstanding concerns among economists and budget analysts about the country's fiscal trajectory, particularly given a combination of heavy government borrowing, sustained high spending, and repeated rounds of tax reductions carried out by both Democratic and Republican administrations over many years.
Maya MacGuineas, president of the Committee for a Responsible Federal Budget (CRFB), a nonpartisan budget watchdog, noted that the debt's impact extends far beyond government balance sheets. "$40 trillion of debt doesn't exist solely on the government's ledgers; it is felt throughout the economy and finds its way to the pocketbooks of people one way or another," she stated.
How Quickly Is Debt Accumulating?
The pace at which US debt is growing has accelerated significantly during the 2020s compared to prior decades. Total debt has doubled since January 2017, when it stood at approximately $19.95 trillion. During Donald Trump's first presidential term, public debt increased by $7.8 trillion, largely driven by pandemic-related emergency spending. Under the Biden administration between 2021 and 2025, an additional $8.4 trillion was added as post-pandemic borrowing continued.
Since Trump returned to office in January 2025, debt has grown by another $3.8 trillion. Notably, the debt crossed the $39 trillion mark just five months before reaching $40 trillion — a pace that underscores how rapidly obligations are mounting. For historical context, it took the United States nearly two centuries to accumulate its first trillion dollars in debt, a milestone reached in 1981.
The Congressional Budget Office (CBO) now projects that debt as a share of gross domestic product (GDP) will rise from 101 percent in 2026 to 120 percent by 2036, surpassing even the previous US record of 106 percent recorded after World War II.
Why Is the Debt Growing So Fast?
Emergency Spending During Crises
Two major economic crises in recent decades significantly accelerated government borrowing. The 2007–2009 financial recession required substantial stimulus measures, while the COVID-19 pandemic between 2020 and 2023 prompted even larger expenditures. Pandemic-related spending alone accounts for roughly one-third of the debt accumulated since 2017.
Revenue Shortfalls and Structural Spending Pressures
Analysts point to a persistent gap between government revenues and expenditures as a core driver of debt growth. The US spends approximately $7 trillion annually, with around 60 percent directed toward Social Security payments, healthcare programs such as Medicare and Medicaid, and veterans' services. In contrast, monthly revenues consistently fall well short of outlays. In July alone, the government collected $334 billion in taxes while paying out $766 billion — nearly double what it brought in.
Tax Cuts and Their Impact
Despite rising costs, significant tax reductions have been implemented. During his first term, Trump signed the Tax Cuts and Jobs Act of 2017, which lowered the corporate tax rate from 35 percent to 21 percent. In 2025, his administration passed the "One Beautiful Bill Act," which made those reductions permanent and raised the debt ceiling by nearly $5 trillion, while also cutting Medicaid spending by 12 percent. Corporate income taxes now represent only about 9 percent of federal revenues, compared to roughly half coming from individual income taxes.
Surging Interest Payments
As interest rates rose to combat post-pandemic inflation, the cost of servicing the national debt has also climbed sharply. The US now spends approximately $1.1 trillion per year on debt interest — slightly more than its annual defense budget — making interest payments the second-largest category of federal spending after pension obligations.
Who Does the US Owe?
Roughly 80 percent of gross debt, or about $32 trillion, is owed to public creditors. Of that, approximately $21 trillion is held domestically by entities including the Federal Reserve ($4.5 trillion), mutual funds ($5.2 trillion), commercial banks ($2.1 trillion), pension funds ($1.1 trillion), and state and local governments ($1.6 trillion).
Foreign creditors hold around 32 percent of gross debt — up dramatically from just 5 percent in 1970. The largest international holders include Japan ($1.2 trillion), the United Kingdom ($889 billion), and China ($683 billion), along with more than 30 other nations and private investors. The remaining 20 percent of gross debt is owed intra-governmentally and does not directly affect external finances.
What Are the Potential Consequences?
Economists warn that unchecked debt growth could trigger significant economic disruptions, including potential hyperinflation, higher interest rates, and reduced private investment. Slower economic growth could follow as investor confidence wanes. Lawmakers may eventually face pressure to introduce painful austerity measures, including tax increases or cuts to social safety net programs.
The repercussions could span generations, with younger Americans potentially bearing higher financial burdens for decades. Given the United States' central role in the global economy, a domestic fiscal crisis would also carry serious implications for international markets and trading partners.
Budget experts suggest that addressing the problem requires an immediate halt to new borrowing and the establishment of a bipartisan fiscal commission to develop long-term solutions — steps that, given current political dynamics, remain difficult to achieve.
