Hormuz Attacks Hit Record as Iran Expands Its Maritime Siege
Ship attacks near the Hormuz Strait have reached a historic high, with Iran striking vessels hundreds of kilometers from the chokepoint itself. The escalation is throttling crude flows and forcing global buyers to reconsider their energy supply chains.
The numbers no one is talking about
Twelve ships reported attacks near the Hormuz Strait in a single week — the highest tally since the United States and Israel opened hostilities with Iran. On October 11 alone, six vessels were struck, setting a daily record. That week followed ten reported attacks the week before, and four more came in during the days that followed.
But the headline number misses the real story. The attacks are moving farther from the strait itself. A Nicaraguan-flagged tanker called the Petrol Dolphin was hit by drones over 250 kilometers away, near Oman’s Sohar anchorage. Another vessel was struck more than 500 kilometers from Hormuz, off northern Qatar. A third attack hit waters near the UAE’s Al Jazira Al Hamra. Iran is not defending a chokepoint anymore. It is wageing a widening maritime campaign.
What is Iran trying to do
Martin Kelly, CEO of Orbital Risk Intelligence, told BBC Verify that Iran has adapted its strategy precisely because its control over the strait is weakening under US and partner naval presence. The goal, according to Kelly, is not merely to damage individual ships but to deter others from sailing at all. When attacks happen almost daily, sometimes multiple times per day, the calculus changes for shipowners, insurers, and charterers.
The Iranian Revolutionary Guard Corps has confirmed it is targeting ships beyond the strait and announced new deployment patterns across the region. Its navy warned explicitly that operations would not be confined to Hormuz. That is not rhetorical posturing. The data shows it.
The crude flow is already contracting
Before the war, approximately 17 million barrels per day moved through the strait. By late September, that figure had recovered to roughly 15 million. As of October 13, Kepler data puts it at about 12.6 million — and declining. The rebound that emerged after the initial shock of conflict is stalling.
Gulf Arab exporters have shifted to a shuttle system to keep tankers moving. Multiple smaller vessels cross the strait, then offload into larger tankers near the Oman coast, avoiding the most dangerous stretches. Iran considers these transfer routes unauthorized and has threatened them. The system works for now, but it adds cost, complexity, and delay to every barrel that crosses the gulf.
US Navy escort requests surged 85 percent in the first ten days of October compared to the same period in August. More protection is buying time, but it is not free, and it is not a permanent solution.
Who gets hit when the violence spreads
The Petrol Dolphin attack illustrates how far the risk has extended. Eleven Indian crew members were rescued. Two remain missing. The GFS Pride container ship sank after being struck by unidentified projectiles; all 21 crew survived. Iran’s IRGC released video of the sinking and claimed the vessel was carrying 2,500 containers of contraband on an unauthorized route. Whether that claim holds up matters less than the fact that Iran is now publicly justifying strikes on commercial vessels far from Hormuz.
When attacks reach Qatari and Emirati waters, they are no longer confined to the traffic lanes that feed global oil markets. They touch LNG exports, regional trade routes, and the broader commercial shipping network that any major economy depends on.
The shadow fleet angle that English-language coverage is underplaying
Here is where the story extends beyond the Gulf. The war has intensified a debate that was already building: should buyers outside the region, particularly in Asia, stop purchasing Iranian crude altogether — or continue buying at discounts and accept the risk?
Iran’s exports have been largely blocked by US sanctions and the wartime blockade, but the shadow fleet — older tankers operated by opaque ownership structures, often flying flags of convenience — has kept some volumes moving through informal channels. When violence escalates, those vessels become both more necessary and more vulnerable. They operate where insured tankers hesitate to go. They carry cargo that mainstream markets have rejected. And when they are struck, as the Petrol Dolphin was, the human and commercial toll falls on the least protected participants in the system.
Major Asian importers — China, India, and others — have historically bought discounted Iranian oil through these channels. The current escalation forces a sharper choice. Continuing to source through shadow fleet tankers means accepting higher insurance premiums, longer detours, and the possibility of direct attacks. Stopping purchases entirely means finding替代 volumes at higher prices in a market that is already tightening.
What happens next
The immediate trajectory is clear: more attacks, more escorts, more costs. Insurers will raise war-risk premiums. Charter rates will climb. Some tankers will simply opt out of the region until the threat recedes.
The broader implication is what English-language coverage has yet to fully connect. This is not a local shipping disruption. It is a stress test for the global energy supply chain. The Hormuz Strait handles roughly a fifth of worldwide oil consumption. Every million barrels per day that fails to cross it puts upward pressure on prices everywhere — Tokyo, Shanghai, Mumbai, Rotterdam.
Iran has signaled that the campaign will widen. The US and its partners have signaled they will keep lanes open. The question is how long either side can sustain that posture before the economic and human costs force a recalibration. For buyers outside the region, the shadow fleet debate is no longer abstract. It is the difference between paying a premium for safe cargo or gambling on cheap barrels that may never arrive.
