Record Ship Attacks Near Hormuz Raise New Questions Over Global Oil Security
October has seen 28 reported attacks on commercial vessels around the Strait of Hormuz, the highest monthly total on record, with more than 30 supertankers damaged since the Iran war began and 11 of them hit this month, according to Reuters.
The Strait of Hormuz, a narrow passage critical to global oil exports, is enduring its most intense month of shipping attacks on record.
There have been 28 confirmed and reported incidents targeting commercial ships around Hormuz so far in October, according to shipping tallies cited in public reporting. Reuters reports that since the Iran war began, more than 30 supertankers have been damaged, including 11 this month alone. Supertankers are the largest class of crude carriers and move large volumes of oil and refined products from Gulf states to international markets.
Even when strikes don’t sink vessels, they cause structural damage, force emergency responses and delay voyages. That disruption ripples through port operations and shipping schedules, with knock‑on effects for delivery times and costs.
For crews on board, each passage through Hormuz now carries sharper risk. Watch routines tighten, lighting tactics change at night, and route adjustments become part of standard operating procedures. Operators must weigh whether to accept higher threat levels or adjust movements in an area where geography leaves few viable alternatives.
Shipowners, charterers and insurers are recalculating. War‑risk premiums typically react to both the number and severity of incidents. A month with record activity pressures insurers to reassess how they price voyages through the strait and what security measures they treat as necessary.
For Gulf exporters such as Saudi Arabia, the UAE, Kuwait, Iraq and Qatar, the concentration of attacks undermines confidence that oil and fuel can move reliably through their main maritime outlet. Pipeline routes that bypass Hormuz exist but have limited capacity and can’t fully replace seaborne flows.
Strategically, the run of attacks underscores how easily pressure at a maritime chokepoint can reach far beyond the immediate region. Even without a formal blockade, any steady pattern of damage to ships can make owners hesitate, push up costs for buyers and force naval forces to commit more assets to protection.
Energy markets react not only to physical disruption but also to perceived risk. Traders monitor ship routing, port congestion and incident reports around Hormuz alongside political signals from Tehran, Washington and Gulf capitals.
Key signals to watch now include any shift in naval deployments by outside powers, updated guidance from major maritime insurers on coverage terms in the area, and visible changes in routing or speeds by large crude carriers transiting the strait.
