Summary: Iran said the Strait of Hormuz would be open to commercial vessels during a 10-day Lebanon ceasefire, but shipping firms and the IMO are seeking clear, verifiable assurances about safety before resuming transit. Key concerns include the risk of sea mines, coordination requirements with the IRGC, and a Tehran-imposed lane near Larak Island that could create navigational and insurance challenges. Major carriers are monitoring the situation or convening crisis teams while markets reacted with lower oil prices and higher stocks.
Strait of Hormuz Declared Open — Shipping Firms Demand Clear Proof of Safety Before Resuming Transit

Shipping companies have cautiously welcomed Iran’s announcement that the Strait of Hormuz will be open to commercial traffic during a 10-day Lebanon ceasefire, but industry leaders and international agencies say they need clear, verifiable assurances — especially about mines and designated safe lanes — before vessels resume passage.
What Iran Said
Iran’s Foreign Minister, Abbas Araghchi, said the strait would be open to all commercial vessels during the ceasefire period. A senior Iranian official told Reuters that commercial ships, including U.S. vessels, may transit but must coordinate movements with Iran’s Islamic Revolutionary Guard Corps (IRGC). Transit would be limited to lanes Iran deems safe, and military vessels would remain barred.
Industry And International Response
The International Maritime Organization (IMO) said it is "verifying the recent announcement related to the reopening of the Strait of Hormuz, in terms of its compliance with freedom of navigation for all merchant vessels and secure passage," according to IMO Secretary-General Arsenio Dominguez.
The Norwegian Shipowners’ Association urged clarification on multiple fronts — including the presence of mines, any Iranian conditions on passage, and how such an arrangement would work in practice. "If this represents a step towards an opening, it is a welcome development," said Knut Arild Hareide, the association’s CEO.
Shipping association BIMCO warned members to be cautious: "The status of mine threats… is unclear and BIMCO believes shipping companies should consider avoiding the area," said Jakob Larsen, BIMCO’s chief safety and security officer.
Safety And Navigational Concerns
A U.S. Navy advisory seen by Reuters likewise flagged that mine threats in parts of the strait are not fully understood and recommended that ships consider avoidance. Analysts also highlighted navigational complications: Kpler lead freight analyst Matt Wright said a Tehran-imposed route through territorial waters near Larak Island could present practical navigation challenges and raise compliance and insurance questions.
Carrier Reactions
German carrier Hapag-Lloyd said it is working to enable its ships to transit the strait "as soon as possible," while its crisis committee works to resolve outstanding questions within 24–36 hours. Danish group Maersk said it is closely monitoring the security situation and will act on its own risk assessments. France’s CMA CGM and Norwegian tanker group Frontline declined to comment.
Wider Impact
U.S. President Donald Trump said Iran had agreed to never close the strait again and that it was removing sea mines. The Strait of Hormuz remains one of the world’s most important maritime chokepoints; past disruptions forced shippers to suspend sailings, reroute cargo and rely on costly detours to maintain flows in and out of the Gulf. Markets reacted to the announcement with a drop in oil prices and modest gains in global stocks.
