According to CNBC, hedge funds are playing an increasingly important role in the $30 trillion U.S. Treasury market, with their holdings of cash Treasuries reaching $2 trillion by the end of 2025, accounting for 7% of tradable Treasuries, a new historical high. The Federal Reserve and the Bank for International Settlements (BIS) warn that the growing involvement of hedge funds, especially in "cash-futures basis trades" financed by high leverage and short-term repo, could amplify systemic risks, leading to market liquidity issues and financial instability. Experts point out that while hedge funds can enhance market liquidity, in extreme situations, forced deleveraging could trigger a chain reaction, exacerbating market volatility.
