Two separate cargo-ship losses near the Strait of Hormuz have made the dangers of transiting the waterway newly visible—but the sinkings were not the result of two attacks in the same 24-hour period.
The Singapore-registered container ship GFS Pride was struck on October 13, caught fire and sank; all 21 crew members were evacuated safely. A second Singapore-registered container ship, GFS Giselle, was struck the following day, suffered hull damage and reached a safe anchorage with all 22 crew safe. The bulk carrier Cape Dao’s loss followed a different timeline: it was hit on September 23, killing one crew member and prompting the evacuation of 26 others. After weeks under tow for salvage, it began sinking on October 13 and was later reported lost. The Pride and Cape Dao are the two sinkings; the Giselle is evidence that attacks are reaching other vessels too.
Who caused the damage remains unsettled. Singapore’s Maritime and Port Authority described the strikes on its ships as involving “unknown projectiles” and named no attacker. Iran’s Revolutionary Guard, meanwhile, said a container ship sank after hitting a naval mine while using what it called an unauthorised route. Maritime security firm MARISKS said there was no independent evidence confirming the mine account. The cause of the Pride’s sinking, and the identity of whoever struck either ship, therefore should not be treated as established fact.
The losses also need to be seen against a longer record, not treated as proof that the two sinkings were part of one coordinated operation. By October 14, the International Maritime Organization’s regional incident log listed 113 confirmed incidents and 24 seafarer deaths. Its entries include damage to tankers, gas carriers, container ships and bulk carriers. The evidence points to a broad and sustained threat to commercial shipping—not, by itself, conclusive attribution of every attack to one actor.
That threat grew out of the war that began on February 28, when the United States and Israel launched strikes on Iran. Iran retaliated across the region and sought leverage over the strait through threats and attacks on commercial vessels. An April ceasefire and a June U.S.-Iran memorandum intended to lead to a wider settlement collapsed amid renewed fighting and formally expired in August. Meanwhile, Washington’s blockade of Iranian ports and a renewed sanctions campaign have added another front to the contest over Gulf shipping.
Iran’s reasons for escalating are partly a matter of attributed claims. Two senior Iranian officials told Reuters that Tehran had changed its tactics against ships it considers to be violating its restrictions, seeking to keep oil prices high and influence November’s U.S. midterm elections. One said the decision came from Iran’s top leadership. Those accounts suggest a deliberate effort to make passage costly and uncertain, but they do not establish who was responsible for the Pride or Cape Dao attacks.
What is at stake extends well beyond the vessels and their owners. Before the war, around 20 million barrels of oil a day passed through Hormuz, about a quarter of global seaborne oil trade; the route also carries roughly 19% of global liquefied natural gas trade. Saudi and Emirati pipelines can bypass the strait, but their combined spare capacity is estimated at 3.5–5.5 million barrels a day—far short of normal oil flows—and they cannot replace Gulf LNG exports. Asian importers, Gulf exporters and buyers of fuel and other cargoes all have reason to worry about prolonged disruption.
For shipowners, the risk is both physical and financial. In July, insurance broker Marsh reported that additional war-risk premiums for Hormuz transits had reached 7.5%–10% of a vessel’s value, while underwriters were becoming less willing to offer spot coverage. That is a dated measure, not a current quote, but it shows how risk can become a direct cost or a reason to defer a voyage. Oil exports through the strait averaged 8.5 million barrels a day in the week ending October 12, CNBC reported—nearly 40% below pre-war levels—after September flows had recovered with U.S. military assistance to tankers. A return to attacks threatens that recovery.
The near-term test is whether ship operators keep transiting, and whether insurers and governments can make those voyages tolerable without widening the military confrontation. The United States is already enforcing its blockade and has helped guide tankers through the strait; Oman, meanwhile, has joined an EU-backed pledge opposing tolls and restrictions as negotiations with Iran over the waterway’s future continue. The IMO has called for renewed cooperation to restore unhindered navigation. None of those steps yet amounts to a settled safe-passage arrangement. Until the political dispute eases, the two wrecks are likely to weigh on decisions made voyage by voyage—by crews, shipowners and insurers, as well as by governments watching the energy and trade that still depends on Hormuz.
