Summary
Ken Griffin, founder and CEO of Citadel, spoke exclusively with CNBC's Sara Eisen on May 5, 2026, at the Milken Global Conference in Beverly Hills to discuss geopolitical risks and market implications arising from escalating U.S.-Iran tensions and the closure of the Strait of Hormuz. The interview occurred as renewed tensions between the U.S. and Iran emerged, though U.S. officials confirmed a cease-fire remained formally in place.
Griffin maintained his previously stated concern—articulated in April 2026—that Strait of Hormuz closure could trigger a global recession through elevated energy prices. When asked whether his outlook had shifted since those earlier warnings, Griffin indicated his analysis remained consistent, emphasizing the critical importance of understanding how long the current geopolitical stalemate would persist. He noted that while the United States military had performed effectively in containing Iranian military capabilities, the fundamental challenge of reopening the straits remained unresolved and difficult to forecast with precision.
The CEO highlighted the key uncertainty facing markets: the duration of the stalemate and the timeline for potential strait reopening. This uncertainty creates substantial risk for energy markets, global supply chains, and broader macroeconomic stability. Griffin's comments underscore the concern held by leading alternative investment managers regarding geopolitical tail risks and their potential to disrupt inflation expectations and economic growth trajectories—factors central to portfolio construction and risk management for institutional investors and hedge funds monitoring commodity exposure and macro positioning.
