Strait of Hormuz Transits Collapse 77% to Just Five Vessels in a Single Day

Summary

Vessel-tracking data showed only five ships transited the Strait of Hormuz on 30 July 2026, down from 22 the previous day, a 77% single-day collapse, with all five routed through the Iranian-side channel. Analysts at Kpler said on the same day that persistent maritime security risk and war-risk insurance costs have become the primary constraints on Gulf crude exports. By contrast the Bab el-Mandeb strait remained comparatively active with 47 transits on 30 July, 27 entering the Red Sea and 20 departing. The Strait of Hormuz normally carries around 20% of global seaborne oil.
