Hedge funds added $400B in Q2 before Fed’s Sept. meeting

Federal Reserve Z.1 data show domestic hedge funds expanded gross assets by $400 billion in the April–June quarter, rising to $3.1859 trillion from $2.7857 trillion in Q1. The increase appears ahead of the Federal Open Market Committee meeting scheduled for Sept. 15-16.

The Fed’s Z.1 table defines gross asset value as total assets rather than gross notional exposure. Securities sold short reported on the table rose to $799 billion in Q2 from $651 billion in Q1, an increase of $148.9 billion. Margin loans owed to U.S. securities brokers and dealers climbed to $131 billion from $110 billion, a rise of $21 billion. Those figures reflect hedge-fund balance sheets for the April–June quarter.

The Fed’s May Financial Stability Report noted comprehensive Form PF data through the third quarter of 2025 placed hedge-fund leverage at or near record levels. A separate Federal Reserve study estimated that large qualifying funds held about $4 trillion of gross Treasury exposure and $3 trillion of repo cash borrowing in September 2025; the Fed’s reports state those measurements cover different fund populations and should not be added together with the Z.1 totals.

Repo is short-term borrowing secured by securities. Research from the Dallas Fed linked hedge-fund repo demand to constraints on dealers and other cash providers and to wider secured funding spreads. Bank for International Settlements research showed higher margin requirements can force leveraged traders to post cash or unwind positions in liquid markets. New York Fed data for Sept. 10 put the Secured Overnight Financing Rate, a broad measure of overnight Treasury-backed borrowing costs, at 3.62%.

Federal Reserve reporting on holdings does not list crypto assets for hedge funds in the published Z.1 table. Any effect on Bitcoin would be indirect and depend on funding conditions and visible selling across risk assets. Observers highlight specific indicators that would increase the likelihood of cross-asset spillovers: tighter secured funding, a wider gap between Treasury cash and futures prices, higher margin demands and clear selling in liquid markets.

The Z.1 quarter-on-quarter increases document balance-sheet capacity that could interact with funding conditions. Market participants are monitoring funding-cost measures, Treasury basis relationships and margin notices ahead of the Fed meeting for signs of stress that might prompt leveraged portfolios to raise cash.
