Iran’s Revolutionary Guard attacked two ADNOC oil tankers in the Strait of Hormuz on August 13, the latest in a campaign that has functionally blockaded the world’s most critical oil chokepoint since mid-July, collapsing daily vessel transits from a historical average of 120 to just 14 and pushing global energy supply routes into uncharted territory.
The assault brings to at least 18 the number of ADNOC vessels targeted since the U.S.-Israel-Iran conflict erupted in late February 2026, a toll that includes one fatality and 20 injured crew members. UAE authorities have formally labeled the Revolutionary Guard’s actions as piracy and demanded Tehran restore freedom of navigation, but Iran counters that it maintains absolute military control over its territorial waters — a claim backed by the near-total paralysis of commercial shipping.
Kpler tracking data quantifies the strategic damage: the strait, which normally carries roughly 20% of global oil consumption, has seen its throughput reduced to a trickle. Iran’s blockade, imposed in retaliation for intensive U.S. strikes on southern Iranian positions, has effectively weaponized geography. Approximately 70 commercial vessels have come under fire, suffered projectile impacts, or faced boarding attempts since hostilities began, rendering international naval patrols largely ineffective at restoring normal flow.
For energy markets, the implications extend far beyond immediate supply disruption. The Hormuz crisis has introduced a structural risk premium that current pricing barely reflects, while forcing a costly rerouting of cargoes around the Cape of Good Hope. With neither side showing willingness to de-escalate and the legal framework for maritime security in the Gulf effectively suspended, the strait’s status as a reliable energy artery is no longer a planning assumption — it is an open question.
