A prolonged closure of the Strait of Hormuz for six months would tip the global economy into recession, according to Citadel’s Ken Griffin.

(P1) A continued closure of the Strait of Hormuz lasting six months or more would push the world into a global recession, Citadel CEO Ken Griffin said Tuesday. The warning from the billionaire hedge fund manager highlights the severe economic stakes of the ongoing U.S.-Iran standoff, which has already sent U.S. gasoline prices above $4 per gallon.
(P2) "The real issue here is the liquidity mismatch between the wealthy investors and the duration of the investments,” Griffin said in a separate interview with the Financial Times regarding private credit, a statement that underscores his focus on systemic risks. His Hormuz warning was delivered to CNBC on May 5.
(P3) The geopolitical chokepoint, responsible for about 21% of global oil trade, has seen tensions escalate, impacting multiple markets. Average U.S. gas prices have hit $4.18 a gallon, their highest point since the conflict began. Meanwhile, the U.S. administration is preparing fertilizer initiatives for farmers hit by rising costs, and budget airlines are seeking $2.5 billion in government aid to offset jet fuel prices, according to the Wall Street Journal.
(P4) The standoff has become an "economic waiting game," said Kristian Coates Ulrichsen, a fellow at Rice University’s Baker Institute, with both the U.S. and Iran testing each other's economic pain thresholds. While Iran faces a potential collapse with only 12 to 22 days of oil storage capacity remaining, a recent poll from the Associated Press and NORC shows 76 percent of Americans disapprove of the administration's handling of the cost of living.
The immediate spike in gasoline prices tells only part of the story, with experts warning of a more significant, delayed inflationary wave. Because oil and natural gas are critical inputs for manufacturing and logistics, higher energy costs are slowly cascading through global supply chains.
“The effects move slowly and appear in places people do not connect to energy,” says Tibor Besedes, a professor of economics at Georgia Tech. “Oil and natural gas are part of the cost structure for an enormous range of goods.”
The strait is a key corridor for naphtha, a feedstock for plastics, packaging, and pharmaceuticals. It also handles one-third of global urea exports, a key fertilizer component, where prices have already climbed sharply. Experts suggest the full impact on food prices may not be felt for another six to 12 months. Unlike other logistical blockages, the Strait of Hormuz has no scalable alternatives, with existing pipelines able to replace only a fraction of the 20 million barrels per day that normally pass through.
The economic pressure is not distributed evenly. While Iran is losing up to $250 million per day and facing what President Trump called a "State of Collapse," some of its regional rivals are benefiting.
According to a Goldman Sachs analysis, Saudi Arabia is set for a revenue windfall. The kingdom has been able to divert the bulk of its crude exports to the Red Sea, allowing it to capitalize on higher prices that more than offset lost shipments through the strait. The United Arab Emirates, by contrast, is likely suffering a steep fall in oil income. For the United States, the Strategic Petroleum Reserve provides a buffer, but experts note a gap remains between enabling capacity and sustaining resilience.
The last disruption on this scale was the tanker war of the late 1980s. As negotiations between the U.S. and Iran remain deadlocked, the next two weeks will be "critical" in determining whether Iran's production cuts outpace the impact of rising oil prices on the global economy, according to Bloomberg Economics.
