Summary
Global hedge funds endured their worst monthly performance in more than four years during March 2026, as escalating conflict between the US, Israel, and Iran triggered acute volatility across equities, fixed income, and commodities. The S&P 500 declined 4.63% in the quarter while the Nasdaq 100 fell 4.87%, forcing institutional investors to reassess positioning in macro-sensitive strategies that had delivered exceptional returns in 2025. The forced liquidations were broad-based: Goldman Sachs data showed hedge funds selling global equities for a fourth consecutive month at the fastest pace in 13 years.
Ken Griffin's Citadel, operating with $69 billion in assets under management as of March 1, faced mixed results across its multistrategy platform. The flagship Wellington fund declined 1.9% in March but remains up approximately 1% year-to-date. However, the firm's Global Fixed Income Fund—more directly exposed to macro turbulence—fell 8.2% in March and is down 5.5% for the full year. Citadel's fixed-income and macro trading operations shed roughly $1 billion in value during the period. Griffin publicly acknowledged that investors were caught "flat-footed" by the geopolitical crisis, describing it as a case where market participants underestimated the resilience and strategic positioning of adversaries.
Citadel was not alone in suffering losses. ExodusPoint declined 4.5% in March and 2% for the quarter; Balyasny Asset Management fell 4.3% in March and 3.8% for Q1; Brevan Howard's Master and Alpha Strategy funds were down 2.4% and 1.7% respectively through early March; and Diego Megia's Taula Capital, managing $7 billion, dropped more than 3% at the start of the month. Millennium Management's flagship fund lost 1.2% in March, reducing year-to-date gains to 1%. PIMCO's Commodity Alpha Fund, a relative-value strategy, declined more than 20% year-to-date, with acute losses recorded in early March.
Performance divergence during the crisis week proved instructive for allocators. While Citadel's Wellington lost 2% and its Global Fixed Income Fund fell 4.75% in a single week, D.E. Shaw's Oculus gained 0.3% and its composite fund gained 2.2% during the identical period. This dispersion reflected differences in risk allocation, hedge responsiveness, and macro concentration rather than fundamental manager quality—all institutions operate at world-class levels. The episode crystallized a critical question for family offices and institutional investors: performance during crisis weeks reveals not alpha generation ability but rather the robustness of risk infrastructure and the effectiveness of defensive positioning prior to exogenous shocks.
