Hedge funds have amassed unprecedented leverage in the US Treasury market, prompting regulators and analysts to warn of increased vulnerability to market shocks amid fears of cascading sell-offs and systemic risk.
Hedge funds have built record levels of leverage in the US Treasury market, intensifying scrutiny over a trade that regulators and analysts fear could magnify instability if borrowing costs rise or positions begin to unwind.
According to the figures cited in the reports, combined repo and prime-brokerage borrowing linked to Treasury strategies has climbed to about $6.6 trillion, while hedge funds now account for roughly 8% of the $31 trillion market for US government debt. The positioning is closely tied to so-called basis trades, in which managers seek to profit from small pricing differences between cash Treasuries and futures contracts.
The scale of the activity has revived concerns about market fragility at a time when traditional buyers of government debt have been retreating. That has left hedge funds filling more of the gap through borrowed money, a dynamic that can support liquidity in calm conditions but leave the market vulnerable to abrupt moves when volatility returns.
The Federal Reserve has already flagged the growing footprint of leveraged investors in Treasuries. In remarks last year, governor Lisa Cook said hedge fund holdings of Treasury cash securities had risen sharply in recent years, underlining how the sector’s exposure has expanded and become more concentrated. The Fed has also noted that these relative-value trades depend heavily on short-term financing, making them sensitive to shifts in repo funding and market stress.
Analysts at Apollo Global Management have warned that a forced unwind could ripple far beyond government bonds, potentially spilling into corporate credit, mortgages and other fixed-income markets. The International Monetary Fund also recently described some hedge funds as systemically important, reflecting the concern that strain at individual firms could propagate through the broader financial system.
For now, the trade remains lucrative enough to keep capital flowing into it, but its size is drawing close attention from policymakers who worry that a reversal in yields or a squeeze in funding could trigger heavy selling. That would be felt not only in Treasuries, but potentially across equities and currencies as well.

- https://www.fxleaders.com/news/2026/04/29/hedge-funds-hit-record-leverage-on-31-trillion-treasury-market-systemic-risk-warning/ – Hedge funds have reached record levels of leverage in the U.S. Treasury market, now owning about 8% of the $31 trillion market. This extreme positioning, driven by the basis trade, raises concerns about potential market shocks if positions unwind due to margin calls or yield reversals. The withdrawal of traditional buyers has led hedge funds to fill the gap with borrowed money, increasing market fragility. Investors and policymakers are closely monitoring the situation as the combination of high leverage and national debt poses significant risks for 2026.
- https://www.bitget.com/amp/news/detail/12560605390319 – Hedge funds have accumulated a record $6.6 trillion in leverage to finance bets on U.S. Treasuries, risking a ‘shockwave’ of forced selling if bonds turn volatile. Regulators warn that hedge fund short positions in Treasury futures have reached historic extremes, confirming the scale of this crowded trade. Torsten Slok, the chief economist at Apollo Global Management, recently warned that a forced unwind could transmit global fixed-income shockwaves. He noted that this forced unwind could impact everything from corporate bonds to mortgages. The IMF’s April 2026 report also noted that some hedge funds have become ‘systemically important,’ meaning that their individual stresses could destabilize the entire broader financial system.
- https://www.hedgeco.net/news/11/2025/treasury-market-warning-the-growing-footprint-of-hedge-funds.html – The Federal Reserve has sounded a clear caution about the increasing role of hedge funds in the U.S. Treasury market, raising questions about risk, leverage and market-stress exposure. In a public address on November 20, governor Lisa Cook highlighted that hedge funds’ holdings of U.S. Treasury cash securities have grown from around 4.6% of outstanding in early 2021 to about 10.3% in Q1 2025—just above the pre-pandemic peak of 9.4%. Much of the hedge-fund Treasury exposure comes from ‘relative value’ trades (cash vs futures, swaps, etc.), which are highly leveraged and reliant on short-dated financing (repo). While these trades typically support market efficiency, they can unravel rapidly in stress events, leading to large Treasury sales and market disruption.

Their positions are linked to bets on price gaps between cash bonds and futures contracts. Regulators and market analysts are monitoring the buildup as hedge funds now control about 8% of the $31 trillion Treasury market. The activity has increased attention on funding conditions and trading flows across global fixed income markets. Market observers continue to assess how funding conditions may respond to changes in interest rates and investor demand across global markets. Attention has also increased around potential spillovers into equity and currency markets globally.
- https://www.federalreserve.gov/econres/notes/feds-notes/sizing-hedge-funds-treasury-market-activities-and-holdings-20211006.htm – Hedge funds’ Treasury exposures have grown and become increasingly concentrated. The extent of hedge funds’ Treasury market activities can be measured by their gross Treasury exposures, as reported in Form PF, and defined as the sum of their long and short exposures of both cash Treasury securities and UST derivatives. As shown by the left panel in Figure 1, hedge fund long and short UST exposures doubled in the two-year span between early 2018 and early 2020. As of February 2020, hedge fund gross UST exposures – long plus short – totaled $2.4 trillion. Hedge funds typically finance their cash Treasury holdings with repo, with the vast majority of hedge fund repo borrowing taking place in the bilateral repo market. Hedge fund repo borrowing, shown in the right panel, also doubled over the two years preceding the pandemic.
