The Leverage of Hedge Funds and the Risk of Their Prime Brokers
Hedge fund leverage amplifies prime brokers’ counterparty risk and threatens financial stability. The paper quantifies leverage across strategies such as global macro and equity long short and links it to broker stress. It introduces risk migration to describe default risk shifts under market shocks. Analysis of 2005--2023 data shows a 1% leverage increase raises broker default probability by 0.15%, notably in discretionary credit strategies. Lower-volatility funds can still strain brokers. More regional and liquidity analysis.
What it examines
This paper investigates how hedge fund leverage affects the financial risk taken on by their prime brokers. Using panel data and econometric models with controls for endogeneity, the authors analyze leverage patterns across different investment strategies to assess the resulting risk exposure and robustness of their findings.
What it concludes
Results show higher leverage increases prime broker risk, especially in strategies like global macro and event-driven funds. The study suggests brokers enhance risk monitoring and regulators consider leverage limits. Future research could explore other markets, additional risk factors, and stress-test scenarios to improve risk management frameworks.
Evidence objects
Hedge fund leverage amplifies prime brokers counterparty risk, varying sharply across strategies like global macro and equity long--short, revealing a critical channel for financial instability spotlighted by new empirical measures.
