At Least 24 Ships Hit in Two Weeks as Oil Shipments Plunge and Iran Warns Vessels Against Switching Off Tracking Systems


US-Israel-Iran War Latest News: The growing danger to commercial shipping in the Strait of Hormuz is forcing energy markets and the global shipping industry to confront a fresh supply threat. As attacks on tankers and cargo vessels intensify during the US-Israel war against Iran, shipping operators face rising security risks, while oil exporters struggle to maintain shipments through one of the world’s most important maritime corridors.

Reports indicate that at least 24 vessels came under attack over two weeks, while daily oil transit through the strait dropped sharply on October 11.

The latest escalation also raises questions about whether ships can safely navigate the waterway as Iran increases warnings against vessels that disable their tracking systems. With diplomatic efforts stalled, the shipping crisis could further disrupt global energy supplies and increase costs for consumers and businesses.

US-Israel-Iran War Latest News: UKMTO Reports Fresh Tanker Attack in Strait of Hormuz

The UK Maritime Trade Operations (UKMTO) agency reported that a tanker was struck by an unidentified projectile while passing through the Strait of Hormuz. Authorities are investigating the incident, and officials have not immediately released further details about the projectile or the extent of the damage.

The latest report follows a series of attacks on commercial vessels in and around the strategic waterway. According to the Financial Times, at least 18 vessels came under attack between October 1 and October 11, while other European security sources recorded six additional incidents during the period. The New York Post also reported that six vessels were targeted on October 11 alone, citing UKMTO data. 

The incidents have affected tankers carrying crude oil and refined petroleum products, as well as cargo vessels. The reported attacks have increased pressure on shipping companies to reassess routes, security arrangements and the risks of sending vessels through the Gulf.

US-Israel-Iran War Latest News: Oil Shipments Through Hormuz Drop to 2.9 Million Barrels

The shipping attacks have coincided with a steep decline in oil movements through the Strait of Hormuz, a key route connecting Gulf energy producers with international markets.

Maritime analytics firm Kpler reported that oil flows through the strait averaged 15.5 million barrels per day in September, approaching the pre-war range of approximately 17 million to 20 million barrels per day. However, transit volumes fell to just 2.9 million barrels on October 11, according to reports on the latest shipping data.

The seven-day average also dropped to 43% below pre-war levels, indicating that the disruption extends beyond a single day’s decline.

Lower transit volumes can delay deliveries to refineries and increase competition for available supplies. Shipping companies may also face higher costs as they seek safer routes, while buyers could encounter longer delivery times and greater uncertainty over fuel availability.

US-Israel-Iran War Latest News: Iran Warns Ships Against Switching Off Transponders

Iran’s Islamic Revolutionary Guard Corps (IRGC) has issued a warning to vessels that switch off their navigation and identification systems while travelling through the Strait of Hormuz.

The warning follows reports that some ships have disabled their transponders to avoid detection while passing through the waterway. Iranian officials have linked such activity to alleged illegal oil smuggling and warned that vessels operating without tracking signals could face military action. IranWire reported on October 12 that the IRGC Navy had threatened ships disabling their navigation and identification systems.

The warning adds another layer of risk for ship operators. Turning off tracking systems can make it harder for other vessels and maritime authorities to identify a ship’s location, while keeping them active may expose its movements to hostile forces.

The situation leaves shipping companies facing difficult security decisions as they try to move cargo through a corridor that remains vital to global trade.

US-Israel-Iran War Latest News: Think Tank Warns Iran Could Improve Anti-Ship Missile Capabilities

The Institute for the Study of War, a Washington-based think tank, has warned that Iran could be strengthening its ability to target vessels at sea.
“Iran may be developing its anti-ship missile capabilities to improve its ability to target vessels,” the think tank said in its latest analysis.
The assessment adds to concerns that the attacks could become more difficult to counter if Iran improves its ability to strike ships. The threat also extends beyond the immediate passage through the Strait of Hormuz, with earlier incidents reported in nearby Gulf waters, including off Qatar.

At least a dozen ships were attacked during the week ending October 5, according to reports, marking the highest weekly total since the conflict began. The subsequent rise in incidents has heightened concerns about the safety of crews and the possibility of further interruptions to maritime traffic.

US-Israel-Iran War Latest News: Oil Prices and Fuel Costs Face Further Pressure

The decline in oil shipments through Hormuz has added to uncertainty in global energy markets. Brent crude has remained above $105 per barrel amid concerns that further attacks could restrict supplies, while fuel prices in the United States have also stayed elevated.

According to the American Automobile Association figures cited in reports, average US petrol prices remained above $4.31 per gallon over the preceding month, while diesel reached $6.27 per gallon on Tuesday.

If attacks continue to restrict shipments, refiners and fuel buyers may need to compete for supplies available through other routes. That could raise transportation and insurance costs, with potential knock-on effects for businesses and consumers.

However, the final impact on oil prices will depend on how long the disruption lasts, whether producers can maintain exports and whether diplomatic or security measures restore confidence in shipping through the strait.

The immediate challenge is restoring safe passage for commercial vessels while preventing the conflict from spreading further across the Gulf. Ship operators will continue to monitor UKMTO advisories, security warnings and the status of shipping routes before making transit decisions.

The number of reported attacks, the decline in oil flows and Iran’s warnings over tracking systems all point to a difficult operating environment for maritime trade. Until security improves, the Strait of Hormuz will remain a major source of uncertainty for energy markets.

A sustained recovery in shipping volumes could ease pressure on oil supplies. Further attacks, however, could deepen disruptions, increase transport costs and prolong volatility in international crude markets.
