Fed's Hammack: It's a reasonable question to ask if it's better to be in Treasuries or in repos

The Federal Reserve’s ongoing quantitative tightening (QT) has intensified debates about the relative merits of investing in U.S. Treasuries versus repo markets, as liquidity dynamics and risk profiles evolve. Hedge funds, which maintain concentrated Treasury exposures, often leverage repo financing to amplify returns, with many transacting at zero or negative haircuts according to Federal Reserve analysis. This practice allows for high leverage—up to 56-to-1 in Treasury repo trades—but exposes funds to sharp margin calls during market stress. Recent Fed analysis highlights that QT reduces Fed-provided liquidity, increasing repo rate sensitivity to Treasury issuance. For instance, a $100 billion rise in Treasury coupon issuance has historically widened repo-ON RRP spreads by 5–6 basis points as data shows. While current repo rate sensitivity remains lower than during prior QT cycles, signs of tightening persist as the Fed’s balance sheet shrinks.

Investors must weigh Treasuries’ perceived safety against repo’s yield potential. Treasuries offer stable collateral value but face downward pressure from increased issuance. Repos, while offering higher returns, carry counterparty risks and volatility tied to liquidity conditions. The Fed’s data suggest that elevated hedge fund leverage and low haircuts could amplify market dislocations during stress, yet repo rates remain supported by ample reserves according to Federal Reserve research. For now, the choice hinges on risk tolerance: Treasuries provide capital preservation, while repos offer yield but require careful monitoring of liquidity and leverage risks. As QT progresses, market participants should remain attuned to shifting supply-demand imbalances and potential regulatory responses as Fed analysis indicates(https://www.federalreserve.gov/econres/notes/feds-notes/repo-rate-sensitivity-to-treasury-issuance-and-quantitative-tightening-20250212.html).
