Key Takeaways
  • • March market turbulence—triggered by German policy shifts and U.S. tariff uncertainty—produced sharply divergent hedge fund performance, with major multi-strategy funds posting losses while niche strategies and smaller, more agile funds generated positive returns.
  • • Citadel and Millennium Management declined -0.8% and -2.0% for Q1 2025, respectively, while ExodusPoint gained 3.5% and Balyasny Asset Management returned 2.5%, demonstrating significant performance dispersion among top-tier multi-strategy vehicles.
  • • Deleveraging in early March forced large hedge funds to face margin calls and cut equity exposure, with losses concentrated in market-sensitive stocks including U.S. mega-cap technology names; however, some funds profited from secondary exposures including swap spreads and macro positions.
  • • German 10-year bonds experienced their largest weekly selloff since 1990, the euro posted its biggest monthly gain since 2022, and the S&P 500 fell 5% in its worst week in six months, creating both challenges and opportunities across hedge fund strategies.
  • • Asia-based multi-strategy funds demonstrated relative stability; Singapore's Dymon Asia Capital returned 2.8% for Q1, suggesting geographic and structural diversification insulated some managers from peak March volatility.
Summary
March 2025 marked a pivotal month for global hedge funds, with market dislocations stemming from German policy uncertainty and escalating U.S. tariff concerns producing stark performance divergence. German 10-year government bonds suffered their largest weekly selloff since 1990, while the euro appreciated by its largest monthly margin since 2022. The S&P 500 fell approximately 5% during its worst week in six months, creating a challenging environment for conventional equity-long strategies.

The largest multi-strategy hedge funds bore the brunt of March volatility. According to sources familiar with the performance data, Citadel returned -0.8% for the quarter, while Millennium Management posted -2.0%. Both firms, among the world's largest hedge fund operators, faced margin calls as risky markets forced deleveraging. UBS noted in a March 27 client communication that major funds moved quickly to raise cash and mitigate losses, while attempting to preserve profitable positions in secondary areas such as swap spreads and macro exposures. Portfolio losses centered on market-sensitive equities, particularly the largest U.S. technology stocks that experienced broad-based declines.

Conversely, more specialized and nimble strategies capitalized on March dislocation. ExodusPoint generated positive March performance that produced a 3.5% quarterly return, while Balyasny Asset Management finished Q1 up 2.5%. These results underscore the advantage smaller, specialized funds maintained in rapidly shifting markets. Asia-based multi-strategy funds demonstrated relative resilience; Singapore's Dymon Asia Capital returned 2.8% for the quarter, suggesting that geographic diversification and structural differences in regional capital market exposures provided some cushion against peak volatility.
