Iran Changes Hormuz Tactics as Attacks Put Shipping Under Pressure
Iran is changing its approach to shipping in and around the Strait of Hormuz, two senior Iranian officials told Reuters on 14 October 2026. They said a goal was to frustrate efforts to lower oil prices before the US midterm elections.
Their account comes alongside maritime warnings documenting projectile strikes, drone attacks and threats to commercial crews. The officials' explanation of Tehran's political aim is an attributed claim; the incidents provide separate evidence of the danger facing vessels using the route.
A wider area of pressure
The officials told Reuters the changes concerned the type and pace of attacks, with operations extending beyond the strait. A US military official separately described Iranian use of small boat spotters after damage to radar capabilities. Those operational accounts came from unnamed officials.
Public maritime records give a more concrete picture of what crews encountered. The Joint Maritime Information Center's 8 October advisory recorded attacks on tankers and liquefied natural gas carriers, alongside a vessel threatened by radio and ordered to turn back.
The advisory distinguished attacks from suspicious activity and disruption. Those categories should not be combined into a single count of ships struck, particularly when an incident is reported several days after it happened.
What the warnings establish
One documented attack involved the tanker ON PEACE on 5 October. The advisory, citing India's Ministry of External Affairs, said 12 crew members were injured and evacuated after an unidentified projectile struck the vessel.
Other entries described vessels continuing their voyages after attacks and crews escaping injury. Iran International's 13 October review of subsequent UKMTO warnings counted 12 commercial ships attacked over a week, including six on 11 October. Some attacks became public only after later warnings were issued.
An unidentified projectile does not establish responsibility for each individual incident. The same JMIC assessment nevertheless documented IRGC harassment and maintained a severe threat level for Hormuz.
A small passage with global exposure
Hormuz connects the Persian Gulf with the Gulf of Oman between Iran and Oman. The US Energy Information Administration calculated that about 20 million barrels of oil a day passed through it in 2024, equivalent to roughly 20 percent of global petroleum liquids consumption.
Around 20 percent of global LNG trade also used the route that year, primarily from Qatar. These are historical baseline figures, not measurements of current wartime traffic.
Brent crude settled at $106.06 a barrel on 14 October, Reuters reported. The price reflects several supply factors; it cannot be attributed solely to an Iranian political strategy.
Blockade and competing claims
JMIC's advisory also confirmed continued enforcement of the US blockade of Iranian ports. Restrictions on access to those ports are distinct from a blanket closure of international transit through Hormuz.
CENTCOM rejected Iran's claim to control the strait in an October statement reported by Anadolu. Competing declarations of control have not removed the practical danger: commercial operators still face attacks, routing pressure and navigation interference. For energy markets, the crucial measure is whether ships and cargo can move safely and consistently.
