Credit Supply and Hedge Fund Performance: Evidence from Prime Broker Surveys

Constraints on the supply of credit by prime brokers affect hedge funds' leverage and performance. Using dealer surveys and hedge fund regulatory filings, we identify individual funds' credit supply from the availability of credit under agreements currently in place between a hedge fund and its prime brokers. We find that hedge funds connected to prime brokers that make more credit available to their hedge fund clients increase their borrowing and generate higher returns and alphas. These effects are more pronounced among hedge funds that rely on a small number of prime brokers, and those ...

Dealers actively manage their inventories away from their limits by selling longer-term securities and ...

Sizing hedge funds' Treasury market activities and holdings

Hedge funds play an increasingly important role in U.S. Treasury (UST) cash and futures markets, a role that has been widely discussed following the March 2020 U.S. Treasury sell-off. In this note, we analyze hedge funds' holdings of UST securities and their UST market activities in normal times and in times of financial market stress using regulatory data from the SEC Form PF.
