US debt hits $40 trillion: Who does Washington owe and why does it matter?

The United States' total debt has crossed the $40 trillion mark for the first time in history, a milestone revealed by a Department of the Treasury update on Wednesday. This ballooning debt, particularly noted during President Donald Trump's second term, has fueled concerns among economists about an impending fiscal crisis. They fear a dangerous combination of substantial borrowing, elevated government spending, and reduced tax revenues could destabilize the world's largest economy.

Despite Trump's campaign promises of cost-cutting and efficiency, US debt has surged dramatically. The Department of Government Efficiency (DOGE) has reportedly reduced federal jobs and global aid since early 2025. The Congressional Budget Office (CBO) had previously predicted the $40 trillion threshold would be reached in 2028, making the current figure significantly ahead of schedule. Maya MacGuineas, president of the Committee for a Responsible Federal Budget (CRFB), highlighted that this debt impacts the broader economy and individuals' finances.

Debt accumulation has accelerated in the 2020s compared to previous decades. The total debt has doubled since January 2017, when Trump began his first term with the national debt at $19.95 trillion. During his initial term, public debt increased by $7.8 trillion, largely attributed to the COVID-19 pandemic response. Since his return to office in January 2025, an additional $3.8 trillion has been added, bringing the total across his two terms to $11.6 trillion.

Under the Biden administration, from 2021 to 2025, the government also continued substantial borrowing and spending, primarily in response to the pandemic, adding $8.4 trillion to the debt. The pace of accumulation has been rapid; the debt hit $39 trillion in March of this year, meaning it took less than five months to add another trillion. For historical context, it took nearly 200 years for US debt to surpass $1 trillion for the first time in 1981.

$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.
