BackgroundCore Concept

Background

The Strait of Hormuz is the world's most critical maritime energy chokepoint — a narrow waterway approximately 33 kilometres wide at its narrowest point, separating Iran to the north from Oman and the UAE to the south. It connects the Persian Gulf to the Gulf of Oman and the broader Indian Ocean, and serves as the sole maritime exit for oil and gas exports from Saudi Arabia, Iraq, Kuwait, the UAE, Qatar, and Iran itself. Roughly one-fifth of global oil and LNG flows — with up to 140 vessel crossings per day at peak — transit through its two navigable shipping lanes of approximately 3 kilometres each (inbound and outbound), separated by a 3-kilometre median zone. No viable alternative export route exists for most Gulf producers at comparable cost or speed.

The legal framework governing the strait is rooted in UNCLOS (United Nations Convention on the Law of the Sea), specifically Articles 37–44, which enshrine the doctrine of transit passage. This doctrine guarantees all ships and aircraft the right of continuous and expeditious passage through straits used for international navigation. Critically, this right is explicitly non-suspendable — no coastal state may legally close the strait or impose mandatory tolls on commercial vessels. Iran, while a party to UNCLOS, has historically contested the scope of these rights, asserting that national security interests justify greater managerial authority over Hormuz traffic. This interpretive tension between Iranian sovereign claims and the UNCLOS transit passage regime is the enduring structural fault line underlying every Hormuz crisis.

The Islamic Revolutionary Guard Corps (IRGC) Navy — designated a Foreign Terrorist Organisation by the United States in 2019 — has been the primary instrument of Iranian coercive maritime strategy, conducting vessel seizures, mine-laying threats, and harassment operations in the Gulf. Iran most notably threatened closure during the 2011–2012 sanctions crisis over its nuclear programme, establishing a pattern of using Hormuz as a strategic bargaining lever.

The Topic Explained

The proposed Iran-Oman deal, as reported, would fundamentally restructure the legal and operational status of the Strait of Hormuz. Under the arrangement, commercial ships would pass through Iranian territorial waters on both inbound and outbound legs of their journey — a formulation that would, in practice, give Tehran a supervisory role over all traffic entering the Gulf. Iran is reportedly seeking transit fees of 5–7% of cargo value, while Oman is negotiating for a lower rate of around 3%, and the United States insists on zero fees. The proposal to make fees nominally 'voluntary' is being floated as a face-saving compromise, though analysts note that the implied threat of Iranian interdiction would make non-payment practically untenable for commercial shippers.

This arrangement would represent a direct challenge to the UNCLOS transit passage doctrine, which prohibits coastal states from imposing fees or conditions on international shipping through straits. …
