Secretary of State Marco Rubio testified before the Senate Foreign Relations Committee that Iran has mined 'large segments' of the Strait of Hormuz, significantly expanding the known extent of explosive threats in this critical maritime chokepoint for global oil shipments [1]. Rubio stated that Iran is also firing on commercial ships and emphasized that any agreement with the U.S. must require Iran to cease these actions, refrain from charging tolls for transit, and assist in removing the mines it has laid [1].
The Strait of Hormuz is a vital artery for the global energy market, with approximately 20% of global oil supplies passing through prior to the outbreak of war between the U.S., Israel, and Iran on February 28 [1]. Since the escalation, oil tanker traffic through the strait has plummeted due to Iranian threats, resulting in what has been described as the largest supply disruption in history [1].
President Donald Trump initially expressed skepticism about Iran's mining activities, but later ordered the U.S. Navy to 'shoot and kill' any vessels deploying mines and accelerated mine-clearing operations in the strait [1]. Despite these efforts, Rubio and other officials acknowledge that Iranian mines continue to pose a significant obstacle to the resumption of normal commercial shipping more than a month after the U.S. began clearing operations [1]. The exact number and locations of remaining mines are unknown, according to Jack Kennedy of S&P Global Market Intelligence, who noted that traffic is unlikely to return to prewar levels until comprehensive demining is completed [1].
The Pentagon has reportedly destroyed numerous mines and over 40 minelaying vessels, according to a White House official, who characterized the disruptions as 'short-term, temporary' [1]. However, the White House did not provide specific figures on the number of mines believed to remain in the strait [1].
CONCLUSION
Iran's extensive mining of the Strait of Hormuz has caused an unprecedented disruption in global oil supply, with commercial traffic unlikely to recover until a thorough demining effort is completed. U.S. officials continue to demand immediate action from Iran, while ongoing military operations have yet to fully resolve the threat.
