Following a framework agreement with the United States, Iran is now requiring all commercial vessels to request permission to transit the Strait of Hormus. Despite this new requirement, passage through the vital waterway will remain free of charge, at least initially. The policy applies to all commercial shipping traffic. This request process is currently set to last for a period of 60 days. The move comes amid ongoing tensions in the region and appears to be a shift in Iranian maritime policy. Details regarding the application process have not been fully disclosed, but the requirement signals increased Iranian oversight of shipping in the Strait.
