JPMorgan Chase & Co. (NYSE:JPM) CEO Jamie Dimon warned that high leverage across financial markets could magnify disruptions, urging investors to be aware of hidden borrowing risks.
On Wednesday, in an interview with CNBC’s Leslie Picker, Dimon said, “Margin debt is the highest it has ever been.” He said that there is significant leverage in the market that isn’t reflected in official margin debt figures because it is “hidden” under other forms of borrowing.
Dimon warned that high leverage across prime brokerages, hedge funds, ETFs, and Treasury arbitrage strategies has increased the risk that a single investor or fund could trigger rapid market volatility.
“When you have that, you do have a higher chance that somebody will disrupt the market in a quick way, and people get rattled over it,” said the JPMorgan CEO.
However, Dimon said current economic conditions differ from the 2008 financial crisis, noting that leverage by itself does not create “systemic” risk. He also cautioned that persistent demand for capital, driven by government deficits, infrastructure spending, and global military buildup, could fuel inflation and keep long-term interest rates elevated.
“When volatility goes up, clearing houses and banks generally ask for more collateral…So you’ll probably see a little bit of that,” he said.
AI Fund Collapse Tests Markets
Dimon’s remarks come as concerns grow over financial market risks, driven by high stock valuations, record hedge-fund leverage, and large Treasury basis trades. Last month, AI-focused hedge fund Situational Awareness suffered steep losses after leveraged technology investments backfired, triggering margin calls and forcing the fund to sell off much of its public-equity holdings.
Ross Gerber said the collapse of former OpenAI researcher Leopold Aschenbrenner’s AI-focused hedge fund was driven by excessive leverage, not flaws in the AI investment thesis. He warned that leverage can rapidly magnify losses, calling the fund’s downfall a lesson in leverage, hubris, and inexperience.
Former hedge fund manager Martin Shkreli said Wall Street’s trading dynamics, not just falling valuations, are accelerating the AI stock selloff. He argued that when heavily leveraged funds face margin calls, rival traders often intensify the pressure by shorting related stocks, forcing liquidations. Shkreli noted that a fund using 4x leverage can be wiped out by a 25% decline, prompting prime brokers to seize and liquidate positions to limit their own risk.
Meanwhile, Dimon said the collapse of Situational Awareness showed that financial markets were resilient enough to absorb the firm’s failure without causing broader market disruption. Notably, JPMorgan was one of the main brokers for Situational Awareness.
