JPMorgan CEO Jamie Dimon warns of high market leverage and pushes AI‑risk coalition

Jamie Dimon market leverage margin debt AI risk coalition Situational Awareness

JPMorgan Chase Chairman and CEO Jamie Dimon told CNBC that overall market leverage is "pretty high" and that margin debt has reached its highest level ever. He said a large portion of borrowing is hidden, not labelled as margin debt, and comes from prime brokerages, hedge funds, leveraged ETFs and Treasury basis‑trade strategies. Dimon warned that a single large investor or fund could quickly disrupt markets, though he stopped short of calling the risk systemic.

He cited the recent collapse of the AI‑focused hedge fund Situational Awareness, which suffered steep losses and was forced to liquidate after margin calls, as an example of how leveraged positions can unwind without sparking a broader crisis. In parallel, Dimon is expanding the Alliance for Critical Infrastructure, an industry group he helped found, to coordinate AI‑risk assessment across more than 40 firms in finance, energy, utilities and other sectors, with the aim of finalising the expanded group by the end of 2026. He also endorsed Federal Reserve Chair Kevin Warsh’s new communication strategy, noting it makes sense for market stability.
