Iran says it will fence off a restricted shipping zone outside the Strait of Hormuz. Will Tehran declare it in force by Sept 13?

Iran's Supreme National Security Council said in early September 2026 that it would establish a restricted shipping zone outside the Strait of Hormuz, but Tehran had not formally declared the zone in force by the Sept. 13 deadline. Council Secretary Mohsen Rezaei said on Sept. 6-7 that Iran would designate an area running from the U.S. Navy's blockade line through the strait and into the Persian Gulf, warning that vessels transiting without coordinating with Tehran would face sanctions affecting insurance and future port access.
The announcement came a day after U.S. forces struck three Iranian oil tankers on Sept. 5, in retaliation for Iranian missile and drone attacks on U.S. warships, part of a broader Hormuz standoff that had already pushed daily tanker transits to their lowest level since May. Iranian officials described the zone only as forthcoming "in the coming days," and no formal notice to mariners or enforcement mechanism was confirmed by Sept. 13.
The community leaned toward yes at 67%, expecting Tehran to follow through quickly given the escalating tanker war. Instead, the announcement remained a stated intention rather than a declared, enforced restriction by the deadline, a community miss.
