The move follows a U.S. naval strike on three Iranian oil tankers after Tehran launched ballistic missiles at American warships amid escalating regional conflict.
Exclusion Zone Warnings and Sanctions Threats in the Gulf
Tehran’s Supreme National Security Council announced that it will implement a new maritime barrier outside the vital waterway aimed at vessels attempting to transit the strait. Mohsen Rezaei, the new head of the council, outlined the parameters of the planned restriction during an appearance on state television.
According to the official announcement, the zone will stretch from the line of the American naval blockade toward the Strait of Hormuz and extend into the Persian Gulf. Authorities stated that any identified ship entering the designated sector with the intent to pass through the strait will be placed on an Iranian sanctions list.
“Any ship that enters this area with the intention of passing through the Strait of Hormuz and is identified will be placed on our sanctions list.”

The announcement arrived with few operational specifics regarding enforcement dates or exact coordinates.
Naval Clashes and Tanker Strikes Near Regional Waters
The standoff escalated sharply over the weekend following a direct exchange of fire between Iranian and American forces. The Islamic Revolutionary Guard Corps (IRGC) claimed its Aerospace Force targeted a U.S. aircraft carrier and a navy destroyer with ballistic missiles, asserting both vessels sustained damage and withdrew from the engagement area.
U.S. Central Command offered a distinctly different accounting of the same engagement. Military officials confirmed that two U.S. warships were targeted by Iranian ballistic missiles while patrolling regional waters, but maintained that both vessels successfully evaded the incoming ordnance. No American personnel were harmed in the attack.
In immediate retaliation for the missile volleys, American forces struck three Iranian crude oil tankers. The conflict itself traces back to February 28, when initial U.S. and Israeli airstrikes struck Iranian territory. Brief lulls, including a temporary June ceasefire memorandum, have repeatedly collapsed as both sides trade economic and military blows.
Commercial Shipping Caught in the Crossfire
Commercial vessels navigating the vital waterway continue to absorb the impact of the hostilities. Emirati authorities reported that a tanker owned by Abu Dhabi’s state-owned Adnoc oil and gas company was struck by a missile while transiting the strait, though company officials confirmed there were no casualties among the crew.
To enforce economic pressure, the U.S. military has maintained a blockade involving more than 20 warships. As of September 6, the naval blockade had redirected 92 commercial ships and disabled three.
Dueling Claims Over Unmanned Vessels and Oil Flows
Friction over maritime access also generated conflicting operational claims. The IRGC asserted that its navy successfully attacked a remotely operated, unmanned U.S. military vessel attempting to enter a protected zone near the Strait of Hormuz. The U.S. military promptly dismissed the Iranian claim as a total lie.
Despite the persistent threat profile, energy markets have maintained partial flows. U.S. Energy Secretary Chris Wright reported that an average of nine million barrels of oil per day continue to move through the strait, supported by regional pipelines and U.S. naval escorts. Wright estimated that these measures have preserved roughly two-thirds or more of pre-conflict flows.
Conversely, Iranian officials insist that domestic production and export channels remain resilient. Rezaei maintained in his broadcast interview that the country continues to sell oil daily, utilizing a shadow fleet to bypass international restrictions and the American blockade.
Stiff Conditions for Reopening the Waterway
Diplomatic efforts to secure a permanent framework for the strategic waterway remain stalled. The Supreme National Security Council issued an uncompromising list of prerequisites for reopening the Strait of Hormuz, stating that the passage will remain restricted until Washington corrects its behavior and permanently ends military operations.
Tehran’s demands include lifting the naval blockade, withdrawing American forces from the area, completely compensating Iran for war damages, lifting all economic sanctions, and unconditionally releasing frozen assets. While Omani mediators described ongoing discussions as taking place in a constructive atmosphere, Iranian Foreign Minister Abbas Araghchi blamed the breakdown of the interim June accord on what he termed U.S. violations of the agreement.
With the 60-day negotiation window approaching its final week and regional leaders expressing deep wariness toward foreign mediators, the prospect of a lasting maritime settlement remains distant as both sides prepare for further confrontation.
