Oman has announced that it will keep the Strait of Hormuz open for shipping without charging any fees and has designated two temporary routes to the north and south of the existing shipping lane to ensure the safe passage of vessels leaving the region.
These measures were implemented amid heightened security risks following the start of the war between the United States and Israel against Iran on February 28. The strait, a vital route for about one-fifth of the world’s oil and liquefied natural gas (LNG) supplies before the conflict, has faced significant disruptions, limiting commercial shipping and destabilizing global energy markets.
Ensuring safety and new traffic schemes
In a notice to mariners, Oman stated that the existing Traffic Separation Scheme (TSS) in the strategic waterway is currently unsafe to use. Instead, vessels transiting the strait can utilize temporary routes located north and south of the existing shipping lanes. The TSS, adopted by the UN maritime agency in 1968, established route lanes through Iranian and Omani waters in the strait.
According to Oman, these measures reflect its responsibility towards the strait, its significance to the global economy, and its commitment to international law and freedom of navigation, citing agreements reached between the United States and Iran. Navigational safety remains a top priority, and due to the increased risk of collisions, a gradual, controlled movement of vessels is required.
Phased plan and responsibilities of participants
Under a phased plan developed by the International Maritime Organization (IMO) in coordination with Omani authorities, vessels will be grouped and given individual instructions on departure times and routes. Before being allowed to transit, vessels will be directed to a designated waiting area in international waters.
Vessels using Oman’s eastern route must maintain communication with shore authorities and comply with all navigational instructions. Ship owners and captains remain responsible for conducting independent risk assessments before voyages. Vessels are required to keep their Automatic Identification System (AIS) activated during transit and report any navigational hazards to the Oman Maritime Security Center.
In its statement, Oman noted that transit fees through the Strait of Hormuz will not be charged, in accordance with the results of recent negotiations between the United States and Iran. Iran and Oman began discussions on the future administration of navigation and maritime services in the waterway on Tuesday, June 23, 2026. While the temporary agreement between the U.S. and Iran allows for the free transit of commercial vessels for 60 days, the negotiations are expected to address long-term arrangements, including any costs associated with maritime services after this period.
