JPMorgan Chase CEO Jamie Dimon cautioned this week that leverage across financial markets has reached historic levels, warning that hidden borrowing could amplify future market disruptions. Speaking to CNBC’s Leslie Picker, Dimon said margin debt has never been higher, though much of it doesn’t appear under that label.

“There’s a lot of margin debt you don’t see because it’s not called margin debt. It’s called other things,” Dimon said, pointing to borrowing channeled through prime brokerages, hedge funds, exchange-traded funds, and Treasury arbitrage strategies.

His comments arrive amid growing scrutiny of market vulnerabilities, with elevated stock valuations, near-record hedge-fund leverage, and sizable Treasury basis trades all raising concerns about potential weak points in the financial system. Dimon warned that such heavy leverage raises the odds that a single investor or fund could spark broader volatility, rattling markets quickly.

Asked about the recent collapse of Situational Awareness — an AI-focused hedge fund that suffered steep losses on leveraged tech bets, triggering margin calls and a forced liquidation of its equity holdings, with JPMorgan serving as one of its prime brokers — Dimon said the episode showed markets could absorb such a failure without wider fallout. He stopped short of calling current leverage levels a systemic threat, drawing a contrast with the 2008 financial crisis.

Beyond market leverage, Dimon flagged inflation risks tied to structural capital demand — citing government deficits, infrastructure spending, and global rearmament as forces likely to push long-term interest rates higher. He reiterated an earlier warning that global remilitarization “could be the skunk of the party” if it pushes bond investors to demand greater compensation for long-dated debt.
