Strait of Hormuz shipping disruptions rise as Iran‑US MoU collapses

International shipping firms are avoiding the US‑controlled alternative corridor along Oman's coast after a series of Iranian strikes on vessels attempting to use the route. Kpler data shows transits through the Strait of Hormuz fell to seven ships on the first day of the renewed US naval blockade, down from 21 the day before. The Persian Gulf Strait Authority reported 56 confirmed incidents and 17 seafarer deaths, while more than 200 non‑Iranian vessels applied for Iranian transit permits, 79% of which were approved, with tankers accounting for 41% and China and India each representing roughly a fifth of the destinations.

Iran has also threatened to involve Yemen's Houthi group to close the Bab al‑Mandeb Strait, a Red Sea gateway, prompting concerns of further disruption to global oil markets; crude prices fell about 2% after the threat was reported. Analysts note that the memorandum of understanding (MoU) signed between the United States and Iran promised “safe passage” for commercial vessels but left key questions unanswered, such as who will administer the route and whether fees can be charged. Iran argues it may impose maritime‑service fees after the 60‑day period, while the United States has reimposed its blockade on Iranian ports following renewed attacks on commercial ships. The legal ambiguity and renewed hostilities have kept traffic through the strait far below pre‑war levels.
