Jerome Powell says the $39 trillion national debt is ‘not unsustainable,’ but warns the trajectory ‘will not end well’

Federal Reserve Chair Jerome Powell spoke at Harvard, cautioning that while the national debt is currently manageable, its trajectory poses serious risks that require immediate attention from lawmakers.

On Monday, Federal Reserve Chair Jerome Powell provided a candid evaluation of the United States' fiscal situation during a lecture at Harvard University. He addressed an audience of approximately 400 students, emphasizing that although the national debt currently totaling $39 trillion is manageable, the country’s fiscal trajectory requires immediate legislative attention.

Powell stated, “The level of the debt is not unsustainable, but the path is not sustainable. It will not end well if we don’t do something fairly soon.” This cautionary message is consistent with Powell’s longstanding warning that, while the current debt levels are not alarming, the projected fiscal trajectory is cause for concern. His remarks came amid rising national gas prices, which were approaching $4 per gallon, alongside ongoing geopolitical tensions in Iran, with no resolution in sight despite optimistic comments from President Trump regarding potential peace.

The Federal Reserve Chair highlighted the distinction between the current debt stock and its trajectory. He noted that, as the issuer of the world’s reserve currency and the owner of the most extensive capital markets globally, the U.S. has the capacity to manage a significant debt load more effectively than smaller economies.

In response to a student’s inquiry regarding the point at which the U.S. debt could exceed its natural repayment systems, Powell acknowledged the ambiguity of that threshold. He cited Japan, which maintains a much higher debt-to-GDP ratio than the U.S., but underscored that the direction of U.S. debt growth is clear. “What’s clear is that our debt is growing much faster; the federal government debt is growing substantially faster than our economy,” he remarked. “And that ratio is going up. And in the long run, that’s kind of the definition of unsustainable.”

Moreover, net interest payments on the national debt are forecasted to exceed $1 trillion in fiscal year 2026, nearly triple the $345 billion paid in 2020. In just the first three months of the current fiscal year, interest payments reached $270 billion, surpassing defense spending for the same duration. These figures substantiate serious constraints on budgetary decisions; however, Powell clarified that these are constraints and not indicators of imminent collapse, and conflating the two could mislead the policy dialogue.

Currently, public debt is anticipated to rise from 101% of GDP to 120% by 2036, breaking the post-World War II record, as projected by the Congressional Budget Office.

Seeking balance

Despite the gravity of the situation, Powell did not advocate for an outright reduction of the national debt. He proposed a more pragmatic approach: “We don’t have to pay the debt down. We just need to have primary balance and begin to have the economy actually growing more quickly than the debt.”

Importantly, Powell underscored that fiscal policy is outside of the Federal Reserve’s authority. He humorously remarked on the tendency for his warnings to be disregarded in Washington, stating, “I pretty much limit myself to those high-level points, which essentially everyone ignores.”

It is worth noting that while Powell's assertion regarding the unsustainability of the U.S. debt trajectory is valid on paper, similar concerns have persisted for decades, yet the economic sky has not fallen. Achieving his recommended primary balance, which necessitates economic growth outpacing debt growth, presents considerable challenges. Effectively closing the U.S. government's significant structural primary deficit would require either substantial revenue increases, deep spending cuts in sensitive areas like Medicare and Social Security, or optimistic assumptions about future growth rates.

Importantly, Powell asserted that he is not responsible for resolving this complex issue. The broader implications of his statements highlight the responsibilities faced by the central bank. Throughout his tenure, Powell has staunchly defended the Fed's independence, emphasizing the need to “stick to our knitting” and avoid pressures to use its tools for broader objectives beyond maximizing employment and ensuring price stability. A fiscal crisis that necessitated intervention from the Fed would present the type of mission drift he has consistently warned against.

Powell articulated his governance philosophy with clarity, stating the necessity of maintaining boundaries: “There’s always a time when an administration looks and says, ‘It would be good to use that tool for something else.’ It happens all the time. And we just have to be in a situation where we’re not trying to work against any politician or any administration, but we have to be careful to stick to what we’re doing.”
