The United States has initiated enforcement of a maritime blockade targeting Iranian trade, confirmed by a new advisory from the United Kingdom Maritime Trade Operations (UKMTO). Effective from April 13, 2023, restrictions on access are being applied to Iranian ports and coastal areas, covering the Arabian Gulf, Gulf of Oman, and Arabian Sea east of the Strait of Hormuz. This enforcement includes vessels of any flag that engage with Iranian maritime activities, aligning with earlier communications from U.S. Central Command regarding the impartial execution of the blockade.
While UKMTO has not declared the Strait of Hormuz itself closed, it emphasized that non-Iranian transit should remain unobstructed. However, vessels may encounter military presence and potential inspections. This advisory reflects the increasingly complex environment in these strategic waters, where overlapping control measures and risks prevail. The restrictions encompass all Iranian coastline activities, effectively establishing a maritime boundary around Iranian trade rather than solely focusing on the strait.
Vessels currently in Iranian ports have been given a limited timeframe to depart, with additional details forthcoming. Remaining uncertainties may deter shipowners from returning to the region. As the situation evolves, U.S. President Trump has heightened his rhetoric, asserting that any Iranian vessels approaching U.S. blockade zones will be treated with force, thereby indicating a zero-tolerance stance against disruptions in this vital energy corridor.
