Iran threatens to close Hormuz routes along Oman's coast
Mohammad Reza Naqdi, an adviser to the Revolutionary Guards, said on 7 October that 'illegal' Hormuz routes along Oman's coast would soon be closed. The same day foreign ministry spokesman Baghaei announced agreement with Oman on the coordinates of a seven-mile safe corridor.
According to a Reuters report published by BOE Report, Naqdi claimed on 7 October that several routes along Oman's coast had been opened by blasting rocky passages and were being used for oil smuggling. He argued that the strait is closed and under the full control of Iran's armed forces. Majid Mirahmadi of the Revolutionary Guards said only 10 ships a day pass through the strait, against a pre-war average of 125. The same Reuters report cites Kpler data showing Gulf crude exports rising to 18.3 million barrels a day on a seven-day average on 30 September, above pre-war levels on 14 days in September.
Gulf News reported that foreign ministry spokesman Esmaeil Baghaei said on 7 October that Iran and Oman had agreed on the geographic coordinates of the entry and exit corridors. The two countries also agreed on how to notify the relevant international maritime body. The corridor is seven miles wide and its entrance runs through Iranian territorial waters; the framework was set up on 25 August. According to Gulf News, Tehran links a full reopening of the strait to US commitments under the Islamabad understanding, and the deal does not guarantee unconditional passage to every ship.
The threat targets transits made without Iran's approval. An AIS count by Hormuz.now recorded 17 ships through the strait on 5 October, 7 on 6 October and 10 on 7 October; this count misses ships with transponders switched off and uses a pre-crisis baseline of 84.8. The gap between Iran's baseline of 125 and the AIS baseline of 84.8 shows that the two sides measure the same strait differently. CBS News says 40% of the region's oil no longer uses Hormuz at all, while the US has redirected 130 ships since 14 July.
Talay assessment
Bottom line
On 7 October Tehran sent two messages at once: it will close free passage along Oman's coast and funnel traffic into a seven-mile corridor through its own territorial waters. This is less an attempt to shut the strait than to license passage through it. Kpler's export figure of 18.3 million barrels shows the Gulf does not yet depend on that licence; if the threat is carried out, that buffer will shrink.
Likely effects
- Freight and insuranceNegativeWeeks
If the route along Oman's coast is targeted, every transit without Iranian approval faces the risk of attack, and AIS transits, already down to 10 on 7 October, could fall further.
- Pipeline bypassesNegative1–6 months
The 40% of flows that avoid Hormuz increase reliance on Saudi and UAE pipelines; since these are also targets, the risk of concentration at a single point grows.
- Türkiye's import routesNegative1–6 months
If crude and product cargoes from the Gulf to Türkiye are forced into the Iranian corridor, the risk of delays and extra costs feeds into the energy bill.
Possibilities, ranked
- 1Threat applied selectively50%
Iran pressures transits along Oman's coast with warnings or seizures but does not close the route entirely.
Watch: New UKMTO reports of stoppages or firing off Musandam and Khasab
- 2Corridor goes to international notification30%
Iran and Oman notify the coordinates to the international maritime body and some shipowners begin using the seven-mile corridor.
Watch: Formal notification of the coordinates to the IMO and insurers' recognition of the corridor
- 3Coastal route effectively closed20%
Attacks halt transits along Oman's coast and AIS transits settle permanently in single digits.
