The global economy may be heading toward choppy waters — and Jamie Dimon is sounding the alarm. During a recent interview with Carlyle cofounder David Rubenstein at the Chamber of Commerce, the JPMorgan Chase chief executive warned that America's $38.5 trillion national debt is "not sustainable" — one of two "tectonic plates" he said could one day collide with devastating effect.
"They're difficult, they're moving," Dimon said. "They may crash. We don't know, and we don't know when."
His comments echo growing concern about the country's fiscal trajectory, following a new report from the Committee for a Responsible Federal Budget that warned that high public borrowing levels could spark a sharp economic downturn. Such a crisis, the report said, could begin when investors lose confidence in America's fiscal outlook, leading them to demand sharply higher interest rates — especially on 10-year Treasury notes, which influence commercial real estate borrowing costs.
Rising yields would reduce the value of existing debt and could trigger "cascading failures" at financial institutions as higher interest expenses deepen the debt spiral.
The scale of the challenge is vast. Treasury Department data from the Federal Reserve Bank of St. Louis show the national debt has ballooned by $2.2 trillion between 2021 and 2022, another $1.9 trillion by 2023, $2.5 trillion in 2024 and $3.2 trillion in 2025. If that roughly $2 trillion annual pace continues, the debt could reach $48.6 trillion within five years.
Even so, Dimon struck an optimistic note about short-term economic momentum.
"If you look at the economy today, there's a lot of good short-term things," he said, specifically pointing to fiscal stimulus, the Fed's renewed bond purchases, deregulation and surging investment in AI and U.S. manufacturing as reasons for confidence.
But geopolitics, Dimon added, could pose a more fundamental threat.
"Obviously, there's the terrible war in Ukraine, which we need to do as much as we can to help," he said, describing broader challenges from Russia and China.
"They want to dismantle the system set up by the Western world after World War Two… and that's about the future of the free democratic world."
That global strain is already being felt in financial markets. Japan's bond market crash last week wiped out $41 billion across the country's yield curve, Bloomberg reported, with the 40-year yield hitting a record 4% and the 30-year yield soaring more than 25 basis points — eight times its typical daily move since 2020.
