Federal Reserve Chair Jerome Powell offered a sobering assessment of America’s fiscal health on Monday, telling a Harvard economics class that while the nation’s $39 trillion debt load is not immediately dangerous, the path the country is on demands urgent attention from lawmakers.
“The level of the debt is not unsustainable,” Powell said during a wide-ranging conversation before roughly 400 students, “but the path is not sustainable. It will not end well if we don’t do something fairly soon.”
The remarks extend a consistent warning Powell has sounded for years, that while the debt level is manageable in the short term, the fiscal trajectory is absolutely not. His comments also came as the average national gas price neared $4 per gallon amid a war in Iran that shows no signs of resolving soon, despite President Trump’s remarks about a potential end to hostilities.
Powell was careful to draw a distinction between the stock of debt and its trajectory, noting that the U.S., as the world’s reserve currency issuer and home to the deepest capital markets on earth, can sustain a large debt load in ways smaller economies cannot.
The remarks came in response to a student asking at what point the size of the U.S. debt breaks “the point of natural systems of repayment.” Powell acknowledged that no one knows exactly where that breaking point lies—pointing to Japan as a country carrying a far higher debt-to-GDP ratio than the U.S.—but said the direction of travel was unambiguous.
“What’s clear is that our debt is growing much faster; the federal government debt is growing substantially faster than our economy,” Powell said. “And that ratio is going up. And in the long run, that’s kind of the definition of unsustainable.”
Net interest payments on the national debt are now projected to exceed $1 trillion in fiscal year 2026—nearly triple the $345 billion the government paid in 2020. In the first three months of the current fiscal year alone, interest payments reached $270 billion, already surpassing the nation’s defense spending for the same period. Those are real constraints on real budget choices. But they are constraints, not collapse—and conflating the two distorts the policy conversation. Debt held by the public is projected to surge from 101% of GDP today to 120% of GDP by 2036, eclipsing the post–World War II record, according to projections by the Congressional Budget Office.
Seeking balance
However, Powell did not call for paying down the debt outright. The fix, he suggested, is more mod
