Iran ready to announce restricted zone in Strait of Hormuz, security council secretary claims

What Happened

Mohsen Rezaei, Secretary of Iran's Supreme National Security Council, said on Sunday via state media that a restricted zone would be announced outside the Strait of Hormuz in coming days and would include areas in the Gulf. He added that maps of ships' passage in the Strait of Hormuz, agreed upon with Oman, would also be signed in coming days. The announcement follows mutual strikes: on Saturday the IRGC claimed that the Iranian Navy targeted three oil tankers traveling through the Strait of Hormuz and three US-affiliated ships in retaliation for three oil tankers hit earlier in the day by US forces. CENTCOM did not confirm those strikes. Earlier, CENTCOM announced that US forces had struck three Iranian oil tankers, including one off the coast of Kharg Island near Iran's key oil export hub, which it said was retaliation for the IRGC launching ballistic missiles at two US Navy ships.

Why It Matters

The Strait of Hormuz is a critical chokepoint for global oil transit. A restricted zone announced by Iran's Supreme National Security Council, combined with reciprocal US-Iran strikes on oil tankers and naval assets, signals escalation risk in a waterway where Iranian and US authority claims directly collide. Signed passage maps with Oman could formalize or contest routing rules, affecting shipping security and oil markets.

Watch For

Monitor whether Iran formally announces and enforces the restricted zone, whether Oman confirms and signs the passage maps, and whether CENTCOM or the US Navy respond to IRGC claims of strikes on US-affiliated ships. Watch for further Iranian or US strikes on oil tankers and naval vessels, and any impact on commercial shipping and oil prices in the Gulf.
