The U.S. national debt has surpassed a record $39 trillion, a milestone that comes just weeks into the U.S.-Israeli war in Iran. The unprecedented figure highlights competing administration priorities, from passing a massive tax law and boosting defense spending to chipping away at the debt itself. Experts warn that the long-term trend of borrowing more and paying more in interest will force Americans to face tougher fiscal tradeoffs ahead.

Why it matters

The rising national debt has significant financial implications for Americans, including higher borrowing costs, lower wages, and more expensive goods and services. Advocates for a balanced budget argue that the unsustainable pace of borrowing will burden future generations and force difficult fiscal decisions.

The details

The federal debt has surged under both Republican and Democratic presidents, most recently fueled by wars, pandemic spending, and tax cuts. The U.S. national debt hit $38 trillion five months ago and $37 trillion two months before that. The White House estimates the war in Iran has cost the U.S. more than $12 billion so far, with no clear end in sight.
