The United States national debt reached $40 trillion on Wednesday, according to data released by the Treasury Department. This milestone occurs five months after the debt passed $39 trillion and marks a doubling of the federal debt since 2017, when it stood at approximately $20 trillion. The Treasury’s daily financial update indicates that government spending is currently outpacing tax revenue by more than $2 trillion per year.
Several factors contributed to the recent increase in the deficit. The Supreme Court recently invalidated several of President Trump's tariffs, requiring the Treasury to refund over $100 billion in import taxes collected illegally. Additionally, the nonpartisan Congressional Budget Office estimates that the "One Big Beautiful Bill," a tax law passed by the Trump administration last year, will add $4.2 trillion to the debt through fiscal year 2034.
Spending on interest has now become the federal government’s second-largest expense, exceeded only by Social Security. Interest payments now surpass spending on both national defense and Medicare, totaling nearly $1 trillion in 2025—approximately 14% of all federal spending. White House spokesman Kush Desai stated that the administration is focused on reducing "waste, fraud, and abuse" to manage the debt-to-GDP ratio, while former Representative Carolyn Bourdeaux of Concord Action stated that neither Congress nor the president has a "credible plan" to stop the debt's growth.
The scale of the debt reached $40 trillion this week, which represents approximately $120,000 for every person in the United States, based on the doubling of the debt from $20 trillion in less than 10 years. Economists from the Peter G. Peterson Foundation note that if current spending and tax policies remain unchanged, the national debt is projected to reach $50 trillion within the next six years. This growth is driven by the rising costs of Social Security and Medicare as the population ages, combined with cumulative tax cuts from the last two decades.
The increasing cost of servicing this debt creates a "crowding out" effect, where interest payments consume funds that might otherwise be used for infrastructure, education, or social programs. While some economists, such as Dean Baker of the Center for Economic and Policy Research, argue the U.S. economy is strong enough to handle this burden, others warn that high debt levels limit the government's ability to respond to future economic shocks like recessions or wars. The Treasury Department will continue to release daily debt updates, and the long-term impact of the "One Big Beautiful Bill" will be monitored through the 2034 fiscal year.
