Real-time monitoring of the world's most critical oil chokepoint
The Strait of Hormuz is the 21-mile-wide waterway through which roughly 20% of the world's oil and about a third of seaborne LNG transit. As of 2026 the strait is under IRGC naval blockade, forcing major oil tankers around the Cape of Good Hope and adding roughly 14 days to Asia-Europe routes. For the underlying geography and history, see our explainer on why the Strait is the world's most critical oil chokepoint and our reference page on what percentage of world oil passes through Hormuz. For the resulting market move, see the Oil & Energy dashboard.
IRGC Navy has deployed mines, fast-attack boats, and anti-ship missiles. Commercial shipping insurance suspended for the region.
