New Attack on Strait of Hormuz Shipping Deepens Fears Over Global Oil Supplies
A fresh report of an attack on a vessel transiting the Strait of Hormuz has intensified fears that the widening Middle East conflict could further disrupt one of the world’s most important energy corridors. The UK Maritime Trade Operations (UKMTO) said on Sunday that a vessel was struck by a projectile while moving through the strategic waterway, although the extent of damage and the condition of the crew were not immediately known.
The latest incident comes as commercial shipping through Hormuz is already operating under severe pressure. The waterway has become increasingly dangerous following a series of attacks involving tankers and other vessels, with the International Maritime Organization listing 75 confirmed maritime incidents in the region as of September 10.
The danger to energy supplies has grown further after Saudi Arabia temporarily shut its 1,200-kilometre East-West oil pipeline following a drone attack. The pipeline had become a critical alternative route while shipping through Hormuz was disrupted, carrying an estimated 4 million to 5 million barrels of oil a day, equivalent to roughly 4% to 5% of global supply.
The combination of threats to both maritime routes and alternative pipelines has alarmed oil markets. Brent crude moved back above $100 a barrel during the past week as traders assessed the possibility of prolonged disruptions, while attacks on tankers have raised concerns that the conflict could directly affect the physical movement of crude rather than merely increase geopolitical risk premiums.
The shipping threat is not limited to a single incident. Earlier this month, two supertankers carrying Saudi crude were struck by unknown projectiles while sailing outbound through Hormuz. Each tanker had loaded around 2 million barrels of Saudi crude, according to shipping data cited by Reuters.
On September 9, Iran said it had attacked 10 vessels near the Strait after the United States sank five Iranian oil tankers. The escalation represented one of the largest waves of attacks on commercial shipping since the conflict began and sent Brent crude above $100 a barrel.
The security situation has also changed how tankers operate. Industry participants reported that some vessels are switching off automatic identification systems, making them harder to track, while operators are deploying additional anti-drone measures. Estimates of the amount of oil still moving through Hormuz vary widely, from around 6 million to 10 million barrels per day, reflecting the difficulty of monitoring shipping in the increasingly dangerous environment.
The Strait is particularly important because it connects the Persian Gulf with the Gulf of Oman and the wider Indian Ocean. A prolonged disruption therefore threatens not only Gulf producers but also refiners and consumers across Asia and other major importing regions.
The risk extends beyond delayed deliveries. A successful strike on a heavily loaded tanker could cause a major fire, sinking or oil spill, creating an environmental emergency in addition to an energy crisis. Dozens of vessels have already been damaged in the broader region, although the IMO’s confirmed incident list shows that many attacks have so far resulted in no reported pollution.
Washington has warned that the threat to commercial shipping remains high. A U.S. Maritime Administration advisory says Iranian forces continue to threaten and conduct strikes against commercial vessels in the Persian Gulf, Strait of Hormuz and Gulf of Oman, with threats including missiles, armed drones and unmanned surface vessels.
Diplomatic efforts are continuing, but expectations for an immediate breakthrough remain limited. Iran is expected to participate in talks with Gulf Arab states in Oman on Monday over the future of navigation through Hormuz. Iranian officials have indicated that reopening the waterway would depend on conditions that include recognition of Iran’s control over the passage, a demand rejected by Washington.
For global energy markets, the latest attack therefore represents more than another isolated maritime incident. It comes at a moment when alternative oil infrastructure is also facing attacks and when shipping companies are already reducing or cautiously managing movements through Hormuz.
If attacks continue, the consequences could extend from higher crude prices to rising freight and insurance costs, tighter fuel markets and renewed inflationary pressure. The immediate question for oil traders is no longer simply whether Hormuz can remain open, but how much energy can safely pass through it while the conflict continues to escalate.
