Corridor Brief
Strait of Hormuz
A single point of failure for a fifth of the world's oil — the world's tightest tanker chokepoint, watched from an elevated-and-rising shore, with hundreds of loitering events recorded across the corridor (Global Fishing Watch).
~21M
barrels of oil a day transit this strait — roughly one fifth of global petroleum liquids, through a channel two miles wide at its narrowest.

Assessment
The Strait of Hormuz carries roughly one fifth of the world's seaborne oil through a channel two miles wide at its narrowest, with no overland alternative at scale. Free terrestrial tracking is sparse across the strait, leaving a meaningful share of transiting traffic unobserved by conventional AIS.
Against that coverage gap, several hundred loitering events have been recorded inside the corridor (Global Fishing Watch). The bordering shore is assessed elevated by the Sabian convergence engine.
