Iran’s armed forces have made their position blunt: the Strait of Hormuz reopens when they say it does, how they say it does, and under conditions they define. This latest declaration removes any ambiguity about who holds the leverage over one of the world’s most critical chokepoints.
Roughly one-fifth of the world’s oil trade passes through the Strait of Hormuz.
A collapsed deal and renewed hostilities
A memorandum of understanding between the US and Iran, negotiated around June 17-18, 2026, was designed to cease hostilities and allow toll-free commercial passage through the strait for 60 days. By early July 2026, the MoU had collapsed entirely, with both sides accusing the other of violations.
Between July 12 and 14, renewed strikes between US and Iranian forces escalated tensions further. Disputes over traffic routes to and from the strait made it clear that even the concept of “reopening” was being defined very differently by each side.
Iran’s position now is that any commercial vessel passing through requires coordination with the Iranian Revolutionary Guard Corps navy. The IRGC has imposed specific technical limitations on passage, effectively turning international waters into a controlled corridor. Ships can transit, but only with explicit IRGC permission and under conditions that Tehran dictates.
Oil markets and the supply squeeze
Shipping traffic through the Strait of Hormuz remains significantly below normal levels. The strait has been a conflict focal point since Iran effectively imposed a blockade in late February 2026.
A Polymarket event is currently tracking whether shipping traffic will return to normal levels by July 31, 2026.
