US Rejects Iran’s Draft Hormuz Plan Proposing Ban on US, Israeli Vessels US dismisses Iran’s draft Strait of Hormuz management plan that proposes barring US and Israeli ships, reaffirms free transit rights for all vessels. International Relations · 12 Aug 2026 · GS: GS2, GS3, Essay · Exam yield: High WHY THIS MATTERS The Strait of Hormuz is the world's most critical oil chokepoint, with about one-fifth of global consumption passing through it daily. Any shift in its governance directly impacts global energy security, shipping laws, and India's energy imports, making it a high-yield topic for IR and security segments. IN PLAIN WORDS The Strait of Hormuz is a narrow strip of water between Iran and Oman that serves as the only sea route from the Persian Gulf to the open ocean. For decades, it has been treated as an international waterway where all countries have the right to pass freely under international law. Currently, this principle is being tested because Iran and the United States are negotiating a temporary deal to reopen the strait after recent conflicts. Iran has proposed a new management plan that would permanently change the rules. This draft suggests banning ships from the United States and Israel, and those carrying Israeli cargo, until war damages are paid. It also implies Iran wants to charge fees for passage. The United States has firmly rejected this, stating that no single country controls the strait and that temporary routes will require no approvals or tolls. The core issue is whether a geographic chokepoint can be used as a political weapon or must remain neutral. Think of the Strait like a public road connecting a neighborhood to the main highway. Iran is acting like a homeowner who wants to put up a gate and only let in friends, while the US insists it must remain an open public road for everyone. The current talks are trying to find a temporary fix for the 'roadblock' without setting a precedent that allows the homeowner to permanently control the road. KEY FACTS • US official stated the Strait of Hormuz is an international waterway with no party controlling transit lanes or approvals • Iran’s draft plan, per Fars news, proposes barring US/Israeli ships and Israel-linked cargo until damages are compensated • Temporary Hormuz routes will require no approvals, permissions or tolls under the US position HOW WE GOT HERE The Strait of Hormuz has been a flashpoint since the 1980s Tanker War, but tensions escalated sharply in 2025-2026. A conflict erupted in February 2026 between Iran and a joint US-Israeli military campaign, leading to devastating infrastructure damage in Iran. A ceasefire was announced on April 8, 2026, followed by 45-day truce negotiations. On June 17, 2026, a Memorandum of Understanding was signed by President Trump and Iranian President Masoud Pezeshkian to end the war. This MOU set a 60-day clock for broader talks covering Iran's nuclear program and the strait's status. Meanwhile, the US Treasury designated the Persian Gulf Strait Authority (PGSA) as a sanctions entity on May 27, 2026, complicating any deal involving Iranian administration of the waterway. THE BIGGER PICTURE International — Freedom of Navigation vs. Sovereign Control The US position relies on the principle of 'Transit Passage' under UNCLOS Article 26, asserting that the strait is an international waterway open to all vessels regardless of flag. Iran's draft plan challenges this by asserting riparian rights to exclude specific national vessels. This creates a clash between customary international maritime law and regional security claims, potentially setting a precedent for other chokepoints like the Malacca Strait. → US asserts UNCLOS-based free transit; Iran asserts sovereign right to restrict adversaries. Economic — Energy Security and Shipping Costs Approximately 20 million barrels per day of oil transit the strait, representing about one-fifth of global consumption and 30% of seaborne oil trade [gomarkets.com](https://www.gomarkets.com/en-eu/articles/refreshed-ver-the-hormuz-crisis-explained-what-happens-when-the-worlds-key-oil-chokepoint-stops-flowing-copy). Iran has passed legislation imposing a roughly $2 million transit fee per voyage [eyeondiplomacy.substack.com](https://eyeondiplomacy.substack.com/p/the-dollar-iran-doesnt-need-why-a). If Iran's ban or fee structure is implemented, it would disrupt global supply chains, increase insurance premiums, and impact India's crude import bill. → Disruption threatens 20 million bpd flow; Iran proposes $2M per voyage fee. Political — Sanctions Regime vs. Maritime Administration A major hurdle is the US Treasury's designation of the Persian Gulf Strait Authority (PGSA) as a Specially Designated National (SDN) on May 27, 2026 [hormuztoll.com](https://hormuztoll.com/news/2026/06/14/sanctioning-the-collector/). The PGSA is viewed as an IRGC instrument. Any deal reopening the strait that leaves the PGSA as the collector of fees creates a contradiction: the strait would be 'open' diplomatically but 'closed' commercially for dollar-system operators who cannot legally pay a sanctioned entity. → PGSA is SDN-designated; commercial reopening requires a non-sanctioned civilian administrator. Historical — Evolution of the 'Islamabad Memorandum' Clauses The current negotiations reference 'Point five' of the Islamabad Memorandum, which envisioned toll-free passage for 60 days and a dialogue on long-term administration led by Oman [scenarica.substack.com](https://scenarica.substack.com/p/short-paper-long-assets). Iran's current counterproposal seeks oversight of one lane entirely, moving away from the shared regional mechanism initially proposed by Oman. This reflects a historical pattern of Iran leveraging geography during negotiations. → Current draft rejects Omani regional model; seeks direct Iranian lane oversight. THE BIG DEBATE Should Iran be allowed to impose transit fees or restrict passage for specific national vessels in the Strait of Hormuz? For: • Riparian states argue they bear the security burden and environmental risk, justifying service fees for navigation safety. • Iran claims compensation for infrastructure damage from the 2026 conflict, viewing fees as reparations rather than tolls. • Proponents cite the Malacca Strait model where voluntary fees support regional maintenance and security. Against: • US argues UNCLOS guarantees free transit passage without tolls, prohibiting discriminatory bans based on flag. • Commercial operators warn that SDN-designated collectors make lawful transit impossible for global dollar-based fleets. • Energy importers fear politicizing chokepoints creates instability in global supply chains and spikes inflation. The balanced take: While riparian states deserve support for navigation safety, discriminatory bans violate international maritime law. The solution lies in a civilian, non-sanctioned joint authority collecting service fees, balancing Iran's economic needs with global free transit rights under UNCLOS. ANSWER IT IN MAINS Discuss the strategic significance of the Strait of Hormuz for global energy security and the challenges posed by the recent US-Iran standoff over transit rights. (GS2) How to attack it: Introduce the geography and volume (20m bpd). Discuss the clash between UNCLOS free transit and Iran's proposed ban/fees. Analyze the PGSA sanctions hurdle. Conclude with need for multilateral oversight. Quote this: Reference the 60-day MOU clock and the PGSA SDN designation [hormuztoll.com](https://hormuztoll.com/news/2026/06/14/sanctioning-the-collector/). How does the concept of 'Freedom of Navigation' apply to international straits, and what are the implications of weaponizing chokepoints for the global economy? (GS3) How to attack it: Define freedom of navigation via UNCLOS. Use Hormuz as a case study for economic weaponization (fees/ban). Link to India's energy security and inflation risks. Suggest de-escalation via regional mechanisms.

[geopoliticsunplugged.substack.com](https://geopoliticsunplugged.substack.com/p/hormuz-on-a-knife-edge-rising-hormuz) — Treasury guidance overrides diplomatic signaling. WHAT SHOULD HAPPEN 1. Establish a joint civilian authority with Omani participation to replace the PGSA. This removes the IRGC-linked SDN entity, allowing global operators to pay fees lawfully. (Suez/Panama model referenced in [hormuztoll.com](https://hormuztoll.com/news/2026/06/14/sanctioning-the-collector/)) 2. Implement a 'service-fee' model compliant with UNCLOS Article 26 instead of 'tolls'. This distinguishes between illegal passage taxes and legitimate charges for navigation aids. (UNCLOS Article 26) 3. Utilize the 60-day toll-free window to finalize a regional security dialogue. This builds confidence and separates immediate commercial needs from long-term political disputes.

(Know the countries it lies between and the approximate oil flow (20m bpd).) • UNCLOS (United Nations Convention on the Law of the Sea) — An international treaty that defines maritime zones and rights, including 'Transit Passage' which prohibits tolls in straits. (Article 26 is key for the 'service fee vs toll' distinction.) • SDN (Specially Designated Nationals and Blocked Persons List) — A US Treasury sanctions list; dealing with entities on this list is prohibited for US persons and dollar-system banks. (PGSA was added to this list on May 27, 2026.) • PGSA (Persian Gulf Strait Authority) — An Iranian body designated to manage Hormuz transit; designated as an IRGC instrument and sanctioned by the US Treasury. (The 'collector' problem: operators cannot pay a sanctioned body.) • Transit Passage — The right of ships and aircraft to pass through a strait used for international navigation without delay or tolls. (Core legal principle the US is invoking against Iran's draft plan.)
