Summary
The International Monetary Fund has called for closer monitoring of hedge funds' use of leverage, pointing to a sharp expansion in the sector's size and systemic role, according to a report by Reuters. The IMF estimates hedge fund assets reached approximately $13 trillion in early 2026, compared with around $4 trillion in 2013. That growth has increased the industry's role in trading, market liquidity and the transfer of risk between financial institutions.
Much of the expansion has been driven by leverage, including synthetic leverage created through derivatives. The IMF acknowledges that hedge funds can improve market efficiency and provide liquidity. However, it warns that leveraged positions can amplify market stress when conditions deteriorate, raising the risk of abrupt market dislocations.
Hedge funds have also become significant participants in sovereign debt markets, particularly US Treasuries. The IMF says they now account for around 9% of the Treasury market, more than double their estimated 4% share in 2022. The Fund notes that this presence can support liquidity and price discovery in normal conditions, but that the capacity of these funds to take on substantial risk may heighten the potential for disruption during periods of stress.
A central concern for regulators is limited visibility into hedge fund positions and exposures. The IMF describes the industry as inherently opaque and says data gaps make it difficult for policymakers to assess risks building across the sector. It calls for improved data collection and risk monitoring to help regulators identify vulnerabilities linked to hedge fund leverage and interconnectedness, with publisher reporting noting that policy measures should be calibrated to the source of risk.
The findings form part of a chapter of the IMF's forthcoming Global Financial Stability Report, scheduled for full publication on October 13, 2026.
