The Islamic Revolutionary Guard Corps (IRGC) warned that all vessels transiting the Strait of Hormuz must use routes designated by the organization [1, 2].
This directive increases tension in one of the world's most critical oil chokepoints, where Iran seeks to maintain control following the announcement of a new Omani shipping route [1, 3].
Between June 25 and June 27, 2026, the IRGC said that any vessel attempting to transit the waterway without their approval is acting in a manner that is "unacceptable and dangerous" [1, 2]. The move is intended to ensure safe passage while asserting Iranian authority over the strategic waterway [1, 3].
Lawmaker Ebrahim Azizi reinforced the government's stance on autonomy during this period. Azizi said, "We will use our frozen assets without seeking Washington's approval" [3].
Simultaneously, the IRGC appears to have rejected efforts to establish a direct communication channel with the U.S. military to prevent accidental escalations. An IRGC official said, "There will be no direct communication between the US and Iranian military" [1].
The warning comes as the IRGC monitors the implementation of the new Omani route, which may alter traditional traffic patterns in the region [1]. The Iranian military continues to insist that its oversight is necessary for regional security, despite opposition from international shipping interests [1, 2].
“It is unacceptable and dangerous to transit the Strait of Hormuz without our approval.”
By mandating specific transit routes and rejecting a military hotline with the U.S., Iran is signaling a shift toward more aggressive territorial assertion. This strategy leverages the Strait of Hormuz as a geopolitical tool to counter Western influence and respond to regional changes, such as the new Omani shipping route, potentially increasing the risk of maritime confrontations.
