Hedge funds hold a record share of the $30 trillion Treasury market. What could go wrong?

TL;DR

  • Hedge funds' cash Treasury holdings reached $2 trillion at the end of 2025, representing a record 7% of the marketable Treasury debt.
  • Traditional investors like pension funds are shifting away from long-term government bonds due to structural changes and increased allocations to alternative assets.
  • Hedge funds' aggressive leverage and reliance on short-term financing create potential vulnerabilities, with regulators warning of spillovers and new financial stability risks.
  • Relative-value strategies, particularly the Treasury cash-futures basis trade, often involve substantial leverage, making the market susceptible to rapid deleveraging and volatility during crises.
  • While hedge funds can improve market liquidity and help correct pricing, their growing role also poses systemic risks that regulators must balance.
