Iran Announces Strait Of Hormuz Is Open To All Ships If They Cooperate With Its Navy
15 May 2026

Iran announced that the Strait of Hormuz remains open to commercial traffic, but ships must cooperate with the Iranian Navy.
The Iranian Navy has officially declared that the Strait of Hormuz remains open for international commercial traffic, provided that vessels strictly cooperate with Iranian maritime authorities during transit. This critical chokepoint, which handles a significant portion of the world's oil supply, requires heightened vigilance from tankers and bulk carriers navigating near the Persian Gulf. Masters and shipping companies must monitor updates from the United Kingdom Maritime Trade Operations (UKMTO) to ensure safe passage through these volatile international waters.
Operational compliance in the Strait of Hormuz is governed by the UN Convention on the Law of the Sea (UNCLOS), particularly the provisions regarding transit passage. Vessels must adhere to SOLAS Chapter V, Regulation 34, which mandates voyage planning to ensure safety of navigation. Furthermore, adherence to ISPS Code requirements is essential for security-level compliance. Compliance departments must verify that all bridge teams are familiar with the latest maritime security directives to avoid potential detentions or escalations that could trigger insurance and P&I club liabilities.
Masters and navigating officers must exercise extreme caution when transiting this region. These professionals are required to maintain a continuous listening watch on VHF Channel 16 and ensure that Automatic Identification Systems (AIS) remain active at all times. It is critical to verify that the vessel’s security plan is updated and that bridge teams are briefed on communication protocols with Iranian naval patrols to prevent any misunderstandings that could jeopardize the safety of the crew and cargo.
