On 6 September 2026<\/strong>, Iran\u2019s new Supreme National Security Council secretary, Mohsen Rezaei<\/strong>, told state television that Tehran will announce an exclusion zone \u2014 also described as a restricted or prohibited belt \u2014 outside the Strait of Hormuz<\/strong>. The zone, he said, will start at the line of the United States naval blockade<\/strong>, run toward the strait, and continue into the Persian Gulf. Any ship that enters the area with the intention of transiting Hormuz, and is identified, will be placed on Iran\u2019s sanctions list.<\/strong> Coordinates, start date and enforcement rules were not published. Rezaei said the announcement would come in the coming days and weeks.<\/p>\n

The statement landed one day after the United States said it had struck three Iranian oil tankers<\/strong> in response to ballistic-missile fire at U.S. warships, and on the same weekend Iran claimed it had hit an unmanned U.S. vessel trying to enter the strait \u2014 a claim Washington dismissed as false. Those exchanges sit on top of a war that opened on 28 February 2026<\/strong> and has already turned Hormuz from a routine energy corridor into a contested checkpoint. What is new here is not another claimed strike on a named tanker. It is a legal-operational overlay<\/strong>: a second, Iranian-drawn belt whose edges have not been charted, sitting seaward of a U.S. blockade whose own line Tehran has not defined in public.<\/p>\n

That geometry is the immediate commercial problem. The U.S. military says more than 20 warships<\/strong> are supporting a weeks-long blockade aimed at Iranian ports and oil liftings. As of Sunday, 6 September<\/strong>, Washington said the operation had redirected 92 commercial ships and disabled three<\/strong>. Rezaei, for his part, said the strait was \u201ccompletely closed and under the control of the armed forces,\u201d claimed that only seven or eight<\/strong> essential-goods ships were now moving versus more than 100 before the closure, and said Iran and Oman would shortly sign an agreement on a new corridor whose entry and exit points would sit under Iranian control. Those Iranian traffic figures should be treated as a political claim, not a voyage plan. They still tell operators what Tehran intends to enforce: approved corridor or sanctions exposure<\/strong>.<\/p>\n

For owners, charterers and hull underwriters the gap between \u201cannounced\u201d and \u201ccharted\u201d is the risk. A vessel that is already standing off in the Gulf of Oman, waiting for a U.S. escort window, a war-risk quote, or a Gulf discharge, may now find that the water it is sitting in is later declared part of the exclusion zone. Rezaei\u2019s wording \u2014 identified ships intending to pass Hormuz \u2014 is broad enough to catch AIS-on tankers, dark or spoofed shadow-fleet units, and innocent transits that merely approach the blockade line<\/strong>. Until official coordinates, notice-to-mariners language and a start time are issued, masters cannot prove they were outside the belt. That uncertainty will feed war-risk pricing, club circulars and charter-party safe-port \/ war-risk clauses even before a single new waypoint is published.<\/p>\n

There is a second-order cargo problem. U.S. Energy Secretary Chris Wright said on Sunday that an average of about nine million barrels of oil a day<\/strong> were still moving through the strait, a figure that sat above recent independent tracker averages and that he tied to U.S. Navy escort cover. An Iranian sanctions list layered on top of a U.S. blockade raises the chance that the same hull is treated as non-compliant by both sides: redirected or disabled by one navy, listed by the other. Product, condensate and LNG cargoes that still have a Gulf load or discharge window should be repriced as political cargo<\/strong>, not as delayed but otherwise normal fixtures. Crews remain the first constraint. A paper sanctions listing is not a missile, but it can precede boarding, diversion or a later kinetic event if Tehran treats the list as a targeting cue.<\/p>\n

What Operators Should Note<\/h2>\n
    \n
  • Do not treat the exclusion zone as in force until coordinates, a start time and a notice to mariners exist<\/strong> \u2014 but do treat the announcement as enough to reopen voyage, insurance and clause reviews now.<\/li>\n
  • Plot the last known U.S. blockade line and Iranian territorial-sea \/ TSS limits on the same bridge pack<\/strong>, and keep a written record of why the ship is where it is (awaiting escort, weather, orders). Rezaei\u2019s belt starts at a line Tehran has not published.<\/li>\n
  • Assume identification can mean AIS, radar, boarding or open-source tracking<\/strong>. Dark or spoofed transits are more likely to be treated as hostile, not as a way to stay off a sanctions list.<\/li>\n
  • Ask P&I, hull war-risk and cargo underwriters, in writing, how an Iranian listing would be treated<\/strong> \u2014 as a sanction, as a war peril, or as an uninsured political risk \u2014 before the next Gulf fixture is fixed.<\/li>\n
  • Re-read CONWARTIME, VOYWAR, safe-port and deviation clauses<\/strong> for any ship that might approach the blockade line, even if the nominated load or discharge port is on the Arab side of the Gulf.<\/li>\n
  • Keep Hormuz, the U.S. blockade and any Iran\u2013Oman \u201capproved corridor\u201d as three separate control points<\/strong> in the passage plan. A corridor whose entry and exit sit under Iranian control is not a clearance from U.S. interdiction, and the reverse is also true.<\/li>\n
  • Hold crew-change, stores and bunker calls outside the prospective belt<\/strong> until the zone is charted or formally dropped. Do not put a relief crew into a waiting area that may later be listed.<\/li>\n<\/ul>\n

    Regulas Shipping will keep matching Rezaei\u2019s exclusion-zone language against published coordinates, U.S. blockade tallies and actual Gulf of Oman waiting patterns so operators can see when a political announcement becomes a charted restriction.<\/p>\n","protected":false},"excerpt":{"rendered":"
