Strait of Hormuz

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 vessels have been recorded dark or loitering inside the corridor — a concentration consistent with ship-to-ship transfer and sanctions-evasion behaviour. The bordering shore is assessed elevated, with Iran the principal source of pressure and an active enforcement history on this route.

Assessment: the corridor combines high strategic value, thin conventional visibility, and a large concealed-vessel population — the conditions under which sanctioned or high-risk cargo moves undetected. Vessels transiting or transferring here warrant elevated scrutiny pending positive identification against the dark-vessel and radar record.
