The Iranian Revolutionary Guard Corps stopped four oil tankers on June 25, 2026 [1], after the vessels attempted to transit the Strait of Hormuz without coordination [1].

This escalation in the Strait of Hormuz threatens one of the world's most critical oil transit chokepoints. Any disruption to the flow of energy through these waters can trigger immediate global market volatility and increase regional military tensions.

According to reports, the IRGC deployed missiles and drones to intercept the four tankers [1]. The Revolutionary Guard said that the vessels were violating navigation rules by attempting to pass without the required coordination, which the organization considers a threat to the maritime security of Iran [1].

An IRGC spokesperson said, "It is unacceptable to announce a route through the Strait of Hormuz without coordination with Iran" [1]. The organization said that the intercept was a necessary response to the lack of permission.

An IRGC commander said, "We stopped four tankers that tried to pass the strait without permission" [2]. The operation occurred in the waters between Iran and the United Arab Emirates [1].

While the IRGC reported stopping four vessels, other reports indicated that three Iranian oil tankers were waiting for permission to transit the strait at the time [1]. A Tehran spokesperson said that crossing Hormuz requires coordination with the Revolutionary Guard [1].

The IRGC continues to assert its authority over the waterway, citing the need for strict adherence to its navigation protocols to ensure regional stability [1].

“"It is unacceptable to announce a route through the Strait of Hormuz without coordination with Iran."”

The use of missiles and drones to enforce coordination rules signals a more aggressive posture by the IRGC in controlling the Strait of Hormuz. By treating uncoordinated transit as a security threat, Iran is asserting a level of maritime sovereignty that challenges international norms of freedom of navigation, potentially leading to increased naval presence from global powers to secure energy corridors.
