Iran is cementing its control over the Strait of Hormuz, a critical global oil chokepoint, by demanding detailed information from vessels and forcing them to detour into Iranian waters before being vetted by the Islamic Revolutionary Guards Corps. In some cases, ships have had to pay for passage. This has led to a 90% drop in traffic through the strait, sending global oil prices soaring and creating shortages, especially in Asian nations dependent on Persian Gulf producers.

Why it matters

The Strait of Hormuz is one of the world's most important maritime chokepoints, handling about a third of global seaborne oil trade. Iran's actions to restrict passage through the strait are having major ripple effects on the global energy market and economy, contributing to skyrocketing oil prices, fuel shortages, and threats to food security in many countries.

The details

Iran is now requiring vessels to provide detailed information and detour into Iranian waters before being vetted by the Islamic Revolutionary Guards Corps before being allowed to transit the strait. In some cases, ships have had to pay fees to Iran for passage. This has led to a 90% drop in traffic through the strait since the start of the war, sending global oil prices up sharply and creating supply shortages, especially in Asian nations that rely on Persian Gulf oil producers.

• Iran began formalizing its 'toll booth' regime in the Strait of Hormuz at the start of the war in 2026.
