Ship attack reports near Hormuz reach record high as oil exports slow

BBC News | Joshua Cheetham, Thomas Copeland, Alison Benjamin

Twelve commercial ships reported attacks in and around the Strait of Hormuz between 5 and 11 October, marking the highest weekly tally recorded by the UK Maritime Trade Operations since hostilities began. Six strikes occurred on Sunday alone, including a drone strike against the Nicaragua-flagged tanker Petro Dolphin off Sohar, Oman.

Iranian forces are expanding their targeted zone. The escalating harassment follows increased US Central Command maritime escort operations accompanying shuttled commercial tankers along Oman's territorial waters. In response, the Islamic Revolutionary Guard Corps Navy has repositioned formations to disrupt traffic beyond the narrow choke point. Daily oil flows exiting the strait fell to 12.6 million barrels on 13 October, down from 15 million late last month and a pre-war baseline of 17 million barrels. Meanwhile, Iranian petroleum exports remain completely stalled under a US naval blockade. Recent strikes also sank the container ship GFS Pride and damaged tankers off Qatar and the United Arab Emirates.

Comment

US Central Command's decision to expand escorted transits along Oman's territorial waters has altered the geographic distribution of naval friction across the Persian Gulf. By funneling merchant traffic through coastal shuttle routes to evade core choke points, coalition protection forces have inadvertently concentrated commercial targets near Sohar Anchorage and UAE coastal zones. In response, the IRGC Navy's adoption of a dispersed deployment formation exploits these predictable shuttle assembly areas beyond the immediate Strait of Hormuz.

This spatial expansion of uncrewed aerial vehicle and missile strikes over 500 kilometres from the primary choke point creates severe friction for UKMTO monitoring and merchant routing coordination. This widening risk perimeter imposes compounding war-risk insurance premiums and crew shortages that reduce the net energy throughput of the Omani shuttle corridor despite direct US Navy protection.

Strategic Question for Discussion
As the IRGC Navy expands long-range drone strikes toward assembly zones near Sohar Anchorage, which factor will exert greater influence over Gulf oil throughput — US Navy convoy capacity or commercial war-risk insurance thresholds?
The trajectory indicates that commercial war-risk insurance thresholds will dictate operational continuity long before coalition naval capacity reaches its operational limits. While US Navy escorts can suppress localized tactical threats, skyrocketing hull insurance rates and crew safety concerns at off-strait anchorages like Sohar will ultimately force commercial shipowners to halt shuttle sailings.
