IMF Warns of Hedge Fund Leverage Risks as Assets Reach $13 Trillion
nashnova research
The IMF's latest Global Financial Stability Report flags hedge-fund assets doubling since 2020 to nearly $13 trillion, with $7.7 trillion borrowed. High leverage is concentrated in US Treasuries and AI stocks — two areas where a reversal could trigger cascading sell-offs.
$13 trillion in hedge funds — where does the money come from?
The IMF report covers more than 25,000 hedge funds across 78 countries, with data going back to 1990.
Total industry assets have doubled since 2020 to nearly $13 trillion; roughly $7.7 trillion is borrowed.
This means → for every $1 of their own capital, hedge funds carry about $1.50 in debt — the industry is betting with other people's money at scale.
Derivatives — financial contracts whose value tracks stocks, bonds, or other assets — plus own assets total $42.2 trillion, dwarfing the industry's equity base.
Where is all that money parked?
Over the past three years, hedge-fund exposure to sovereign bonds has doubled; roughly two-thirds of the increase is in US Treasuries.
Their share of the US Treasury market rose from about 4% in 2022 to 9% in 2025, driven mainly by highly leveraged trades.
Meanwhile, stock-holding overlap across funds has climbed steadily since 2022, especially in AI-related names.
In plain terms = everyone owns roughly the same things — Treasuries and AI stocks. If the wind shifts, they all rush for the exit at once.
Why does leverage "snowball" once it goes wrong?
The IMF's core warning: market volatility → fund losses → margin calls (demands to post more collateral) → forced asset sales → prices drop further → more margin calls — a vicious cycle.
This reflects leverage's self-reinforcing nature: each round of selling breeds the next, eventually spilling into the banking system and the real economy.
There is precedent: in 2020, concentrated hedge-fund unwinds in Treasuries caused severe global market dislocations, ultimately forcing the Federal Reserve to intervene.
What does the "Situational Awareness" fund episode reveal?
The hedge fund Situational Awareness used heavy borrowing to bet on AI stocks. When AI shares fell in July, it suffered major losses and faced margin calls.
Ken Griffin's Citadel stepped in and bought its portfolio at a discount — preventing the crisis from spreading further.
This means → this time a "white knight" showed up. But next time? No systemic safety net exists.
What do academics make of all this?
Valentina Bruno, a finance professor at American University in Washington, warned that leverage "that looks perfectly manageable today" could become dangerous "overnight."
Christian Lundblad, a finance professor at UNC Kenan-Flagler, said "losses themselves are not a problem — that's part of the game." The real risk is whether the system can absorb those losses without triggering a chain-reaction collapse.
In plain terms = losing a bet is fine. The danger is when one fund's loss brings the whole building down.
