Key takeaways
- GFS Pride and Cape Dao sank on 13 to 14 October, bringing IMO-based counts of commercial vessels sunk in the war to three.
- IMO, UKMTO and CENTCOM figures measure different things, so incident counts and flow claims cannot be merged into one number.
- Reuters reported that two senior Iranian officials confirmed a tactical pivot against ships on unauthorised routes about ten days earlier.
- War-risk insurance now runs at 6% to 10% of a ship's value, so costs carry much of the pressure.
The Singapore-flagged container ship GFS Pride sank on 14 October, a day after an unidentified projectile struck it. The Antigua and Barbuda-flagged dry bulk carrier Cape Dao sank on 13 or 14 October, more than three weeks after a projectile hit it on 23 September. The Maritime and Port Authority of Singapore (MPA) confirmed that all 21 GFS Pride crew members were evacuated without injury. One Indian crew member of Cape Dao was killed in the 23 September strike. International Maritime Organization (IMO) casualty data, cited by Reuters, gCaptain and CNBC, count the two ships as the second and third commercial vessels sunk since the war began on 28 February 2026.
This analysis uses the two losses as an entry point to a narrower question: why the contest over the Strait of Hormuz is being fought through risk as well as through physical closure. The working thesis is the author's assessment, not an established finding. Oil can still move through the strait under escort, but insurance, freight and crew costs carry much of the pressure, which makes the waterway closer to an asymmetric economic siege than a simple blockade. Sources disagree on the numbers, so each figure below keeps its source, date and scope.
What the sinkings do and do not show
GFS Pride (2,824 TEU, or twenty-foot equivalent units, managed by UAE-based GFS Ship Management FZE) caught fire after the 13 October strike. The MPA condemned the attack as unprovoked and a breach of international law. The Islamic Revolutionary Guard Corps (IRGC) Navy claimed, via Tasnim, that the ship hit a naval mine on an "unauthorized route." UKMTO attributed the strike to an unidentified projectile, and the maritime risk firm MARISKS said Iran's mine account fitted a psychological operations campaign meant to deter commercial shipping. A sister ship, GFS Giselle, took hull damage from an unidentified projectile on 14 October and reached safe anchorage with all 22 crew unharmed.
Cape Dao, managed by UAE-based Peonies Shipmanagement FZE, shows a different feature of anti-ship strikes. The vessel sank weeks after the hit. A struck ship can therefore take weeks to flood or capsize, so casualty and loss counts lag the attacks that cause them. The first sinking was the Maltese-flagged container ship Safeen Prestige, struck in March and later lost north of Hormuz. The IRGC also seized the container ship MSC Francesca in April, which is a seizure rather than a sinking. Crisis.Zone's March report on a Thai bulk carrier struck in the strait recorded the earlier pattern of attacks reaching beyond tankers.
The tallies differ by source and date:
- IMO (mid-September, reported by Marine Insight): 80 attacks on ships in and around the strait and 20 seafarers killed.
- IMO incident list (cutoff 5 October): 93 incidents in the Strait of Hormuz and the wider Middle East, and 24 seafarer deaths.
- IMO incident list, cited by gCaptain (14 October): more than 100 confirmed incidents and at least 24 seafarer deaths.
- UKMTO (UK Maritime Trade Operations), per an Iran International tally: 12 commercial vessel attacks between 5 and 11 October, including six vessels (five tankers and one container ship) on 11 October alone.
- Al Jazeera, citing UKMTO: 15 separate attacks between 6 and 14 October, 11 of them in the final four days.
- UKMTO incident reports, cited by Reuters (14 October): more than 20 vessels attacked in October, mostly oil tankers.

The cost of passage
The volume data point the same way. Before the war, roughly 125 to 140 large commercial vessels crossed the strait each day, carrying about a fifth of global oil and LNG trade, according to Al Jazeera and gCaptain. In the week to 11 October, vessel traffic remained about 75% below pre-conflict levels, Iran International reported.
The financial friction is larger than the volume loss suggests. War-risk insurance now runs at 6% to 10% of a ship's value, which can reach $20 million for a supertanker sailing through the Gulf, Fortune reported on 10 October. Freight for tankers in Hormuz reached a record $1.3 million a day. Tanker captains can earn $100,000 a month for transiting the strait, against about $15,000 normally, plus $50,000 per trip, according to sources cited by the Financial Times, while ordinary sailors can earn four to six times their normal rates. Oil that moves under escort still arrives at a higher price, and under these conditions the cost of risk, not the physical flow, has become the main lever.

What to take from the two sinkings
As of 15 October, three commercial vessels have been sunk in this war, according to IMO-based reporting. IMO data cited by gCaptain on 14 October show more than 100 confirmed incidents and at least 24 seafarer deaths. The more consequential pattern lies in the gap between what moves and what it costs to move it. CENTCOM and the IRGC each assert control, and the data they cite measure different things. The IRGC's mine explanation for GFS Pride is disputed by the maritime risk firm MARISKS, and attribution of most strikes rests on Iranian officials' remarks to Reuters, since UKMTO has not named a party.
Earlier Crisis.Zone reporting recorded the dispute over control of the strait in April and Tehran's March warning of $200 oil. Both contests continue. The open question is whether the political clock that Iranian officials describe, running to 3 November, will tighten or loosen the pressure on shipping. The evidence available as of 15 October does not settle it.
