Reuters and UKMTO reported September 13 that a projectile struck a vessel transiting the Strait of Hormuz, causing a fire and forcing crew evacuation.
Iran said one person was killed and four wounded aboard an Iranian commercial ship struck off Qeshm Island in the strait.
The attack came one day before a regional meeting in Oman on September 14 where Iran plans to present a proposed maritime corridor agreed with Muscat.
Foreign Minister Abbas Araghchi told Al-Araby Al-Jadeed the agreement with Oman does not in any way mean reopening the Strait of Hormuz.
Tehran would reopen the waterway only if Washington returns to commitments under the Islamabad memorandum, Araghchi added.
Saudi Arabia shut its 1,200-kilometre East-West pipeline as a precaution after drone strikes on September 12.
The pipeline had been moving about 4 million to 5 million barrels per day as the main bypass for Middle East oil while Hormuz traffic stayed impaired.
Traders told Reuters Yanbu storage could sustain Red Sea exports for five to seven days if the pipeline remains offline.
After that window, as much as 4 percent of global oil supply could be at risk on top of the millions of barrels per day already lost to Hormuz disruption.
BC Insight and TFI accounts put roughly 45 to 50 percent of globally traded sulfur normally transiting Hormuz, with commercial sulfur cargoes near zero since the February conflict.
Houthi advances along the Red Sea coast and Perim Island capture add pressure on Bab el-Mandeb as an alternative corridor.
For Alberta recovered sulfur on the Vancouver stem, a weekend that closes both Hormuz and Saudi's Red Sea bypass tightens the Pacific swing-supplier window.
Canadian export volumes rose in 2025 and early 2026 as Middle East seaborne stayed shut; any further freight escalation raises insurance and voyage-cost floors on competing Gulf cargoes.
Desk read: September 13 is a freight crisis print, not a price quote. Watch Monday's Oman meeting for corridor language and whether Yanbu storage forces another Red Sea routing scramble.
