Key Takeaways:
A US Navy F/A-18 Super Hornet disabled an oil tanker attempting to breach the Strait of Hormuz blockade, bringing the total to eight vessels struck since April 13.
The US military disabled an unladen oil tanker in the Gulf of Oman on Monday after it ignored orders and attempted to sail to an Iranian port, the eighth vessel struck since the naval blockade began in April.
"Marivex is no longer sailing to Iran," US Central Command said in a statement, confirming the Palau-flagged vessel's engineering and steering spaces were hit by a precision munition fired from an F/A-18 Super Hornet assigned to the USS Abraham Lincoln.
Since the blockade's launch on April 13, US forces have disabled eight non-compliant tankers, diverted 134 vessels for inspection and allowed 42 ships carrying humanitarian aid to pass, according to Central Command. All 24 Indian crew members aboard the Marivex were rescued by Omani authorities and evacuated to Masirah Island, Indian officials said.
The escalation threatens to tighten global oil supply through the Strait of Hormuz, a chokepoint that handles about 21 percent of the world's petroleum consumption. Brent crude prices face upward pressure as traders price in the risk of further disruptions to Iranian oil exports and potential retaliatory actions.
The Marivex was traveling without cargo when it failed to respond to US directions in international waters south of the Strait of Hormuz, Central Command said. The vessel had previously been sanctioned by US authorities for alleged links to Iran, according to Reuters.
The blockade represents the most aggressive US maritime interdiction effort in the region since the Tanker War of the 1980s, when the US Navy reflagged Kuwaiti tankers and escorted them through the Persian Gulf during the Iran-Iraq War. During that period, attacks on commercial shipping pushed oil prices sharply higher and prompted a multilateral naval response.
The sustained blockade removes a meaningful volume of Iranian crude from global markets at a time when OPEC+ supply management has already tightened spare capacity. Iran exported roughly 1.5 million barrels per day before the blockade, according to tanker tracking data, much of which flowed through the Strait of Hormuz. Each disabled tanker reinforces the credibility of the interdiction effort, raising the cost and risk for any vessel attempting to move Iranian oil.
The rescue of the Marivex's 24 Indian crew members highlights the human dimension of the blockade. The All India Seafarers Union said it received distress communication from a crew member shortly after the fire broke out, calling the incident a matter of serious concern. Indian authorities coordinated across government agencies to ensure the seafarers' security.
Shipping insurers are likely to raise premiums for vessels transiting the Gulf of Oman and Strait of Hormuz, adding to operating costs for the global tanker fleet. War risk premiums for the region have already increased since the blockade began, according to industry sources.
