US hits $38T in debt, after the fastest accumulation of $1T outside of the pandemic
Summary
The U.S. gross national debt topped $38 trillion amid a federal government shutdown, according to the latest Treasury Department daily report. That milestone follows the fastest $1 trillion increase outside the COVID-19 period — the nation reached $37 trillion just in August 2025.
Experts warn the growing debt load can push up inflation and borrowing costs, squeeze business investment and make housing and other big purchases harder for future generations. The Government Accountability Office notes rising debt tends to increase mortgage and car loan costs and reduce funds available for wages and investment.
The White House says deficit reductions are underway, citing a Treasury analysis that recorded a $468 billion cumulative deficit from April to September — the lowest since 2019. Still, fiscal groups and economists highlight rapidly rising interest costs that will crowd out other spending: the Peterson Foundation notes interest spending has been large and is projected to grow substantially in the coming decade.
Key Points
- Gross national debt surpassed $38 trillion during a government shutdown.
- This marks the fastest $1 trillion increase outside the COVID-19 era; $37T was reached in August 2025.
- Economists warn higher national debt contributes to inflation and greater borrowing costs for households and businesses.
- The Trump administration points to a reduced cumulative deficit (April–September $468bn) and claims spending cuts and revenue gains are shrinking the deficit.
- Interest costs are rising quickly — the Peterson Foundation warns interest spending will climb sharply, crowding out other investments (noting $4tn spent on interest in the last decade vs an estimated $14tn in the next ten years).
