Iran's Islamic Revolutionary Guard Corps (IRGC) declared the Strait of Hormuz closed to all ships on July 11, 2026 [1, 2, 3].
This closure threatens one of the world's most critical maritime chokepoints, potentially disrupting global energy supplies and escalating military tensions between Tehran and Washington.
The IRGC navy announced that the Strait of Hormuz is closed to all vessels [2]. An IRGC spokesperson said, "The Strait of Hormuz is closed to all ships until further notice" [1]. The ban prohibits any vessel from passing through the narrow waterway located between Oman and Iran [2, 3].
Officials cited two primary drivers for the decision. The IRGC said the closure will remain until the United States ends its military interventions in the region [1]. Additionally, the ban follows an incident where the IRGC fired warning shots at a ship [1, 3].
The U.S. has responded to the escalation by demanding that Iran publicly state the Strait of Hormuz remains open for all [2]. The IRGC statement said that the shutdown is effective until further notice [3].
Naval forces from the IRGC are currently monitoring the waterway to enforce the prohibition [1, 2]. The move comes amid heightened volatility in the region as the two nations clash over military presence and regional influence.
“"The Strait of Hormuz is closed to all ships until further notice."”
The closure of the Strait of Hormuz is a high-stakes geopolitical lever. Because a significant portion of the world's oil and liquefied natural gas passes through this narrow corridor, any prolonged blockade could trigger a global energy price shock and force a direct military confrontation between the U.S. and Iran to ensure the freedom of navigation.
