Iran closes Strait of Hormuz, traffic falls to 6% of normal as demands mount

The Strait of Hormuz, a narrow corridor through which roughly a fifth of the world’s oil supply normally flows, is effectively closed. Iran’s Supreme National Security Council Secretary Mohsen Rezaei confirmed the closure will remain in place until the United States changes its behavior and fulfills specific commitments demanded by Tehran.

The shutdown, which began February 28, 2026, following U.S. and Israeli military strikes on Iranian positions, has now stretched into its sixth month with no credible resolution in sight.

A chokepoint living up to its name

Think of the Strait of Hormuz as the world’s most consequential single-lane road. When it works, roughly 74 ships pass through daily. As of August 22, 2026, that number has collapsed to just four.

That is traffic running at approximately 6% of pre-crisis levels.

Iran’s Islamic Revolutionary Guard Corps has been the enforcement arm of the closure, requiring vessels to submit to vetting and approval processes before any transit is considered. The United States disputes Iran’s characterization of total control, maintaining that limited passages remain possible under American naval oversight.

Mohsen Rezaei, appointed SNSC secretary on August 9, has laid out Tehran’s conditions plainly. The U.S. must end military operations against Iran and its regional allies, lift existing sanctions along with the naval blockade, and withdraw American forces from the region. A June 2026 memorandum of understanding between the two countries was supposed to ease tensions and restore commercial traffic. That agreement has produced little tangible movement.

What $94 oil tells you about market fear

Brent crude has climbed to around $94 per barrel, a price level that reflects something beyond ordinary supply-and-demand math. That premium is what traders call a war-risk premium — the extra cost baked into oil prices when the shipping routes carrying that oil might get a vessel seized or worse.

The Strait of Hormuz sits between Iran and the Arabian Peninsula and connects the Persian Gulf to the Gulf of Oman. Saudi Arabia, the UAE, Kuwait, Iraq, and Qatar all rely on it as their primary export corridor.

How this plays out from here

Iran’s demands, taken together, would require the U.S. to fundamentally reverse its posture in the Middle East — withdrawing forces, dropping sanctions that have been in place for years, and conceding that its military actions against Iran were unjustified. Washington has shown no public indication it intends to meet any of those conditions.

The June memorandum that has gone largely unimplemented suggests both sides have at least sat across a table.
