Citadel founder and CEO Ken Griffin said Tuesday that a prolonged closure of the Strait of Hormuz would push the world into a global recession [1, 2].

The warning highlights the extreme vulnerability of international trade and energy markets to geopolitical instability in the region between Oman and Iran. Because the waterway is a primary artery for oil flows, any significant disruption threatens the stability of the global economy [2, 5].

During an interview on CNBC’s program “The Exchange” with Sara Eisen, Griffin focused on the timeline of such a disruption. He said, "If the Strait of Hormuz stays shut for six months, the world will go into a recession" [1]. According to reports, a closure lasting between six and 12 months would trigger this economic downturn [3].

Griffin said the current state of the global economy is in a "very treacherous moment" [4]. He noted that while the international community would suffer, the U.S. would be relatively insulated from the worst effects. Griffin said, "The United States would be largely shielded because of its energy independence" [2].

The Strait of Hormuz remains one of the most strategically important chokepoints in the world. A shutdown would choke the oil flows that underpin global industrial activity, making a recession nearly impossible to avoid if the lockdown persists [2, 5].

"If the Strait of Hormuz stays shut for six months, the world will go into a recession."

This assessment underscores the shift in global economic risk, where energy security has become a primary driver of macroeconomic stability. While U.S. domestic production provides a buffer against supply shocks, the interdependence of global markets means that a collapse in energy access for other nations would likely trigger a secondary economic crisis within the U.S. through reduced trade and financial contagion.
