# US Treasury Prohibits US Persons from Availing Iran’s Hormuz Safe Passage Services

*New US sanctions bar American entities from using Iran’s government-provided transit guarantees for Strait of Hormuz passage.*

## Why this matters

The story tests UPSC's favourite overlap: energy security, sanctions architecture, and the global commons. It also illustrates how a single designation can paralyse commercial reality despite a diplomatic 'reopening'.

## In plain words

Imagine the Strait of Hormuz as a narrow, crowded bridge that carries one-fifth of the world's oil. For decades, Iran and the US have argued over who controls the toll booth on that bridge. In May 2026, Iran created a new body called the Persian Gulf Strait Authority (PGSA) to manage the strait and collect fees. On 27 May 2026, the US Treasury's Office of Foreign Assets Control (OFAC) added the PGSA to its Specially Designated Nationals (SDN) list, labelling it an instrument of Iran's Islamic Revolutionary Guard Corps (IRGC). This means any American person or company dealing with the PGSA—even paying a 'service fee' for safe passage—faces severe penalties.

The practical effect is a paradox. A June 2026 Memorandum of Understanding (MOU) between the US and Iran aims to reopen the strait, but the entity designated to run it is now sanctioned. The US Treasury has clarified that this exposure applies 'regardless of payment method, including cash, digital assets, and in-kind arrangements' [hormuztoll.com](https://hormuztoll.com/news/2026/06/14/sanctioning-the-collector/). So, a shipowner paying in Chinese Yuan, Bitcoin, or even crude oil barrels still violates US sanctions.

Think of it like a city declaring a road 'open' but simultaneously putting the toll operator on a 'do not pay' blacklist. The road is diplomatically open, but commercially closed for most drivers. Insurers like the Lloyd’s Market Association have already terminated cover for vessels paying these fees, leaving the global fleet stuck between a diplomatic promise and a compliance wall.

## Key facts

- U.S. Treasury has barred U.S. persons from receiving services from Iran’s government related to “guarantee of safe passage” through Hormuz.
- U.S. has imposed sanctions on Iran’s Persian Gulf Strait Authority, established in May 2026 to manage the waterway.
- Iran seeks 5-7% cargo value fees for Hormuz transit, creating compliance issues for global shipping firms due to U.S. sanctions.
- Lloyd’s Market Association clause terminates insurance for vessels paying any Hormuz transit fees, compounding industry challenges.

## How we got here

The current crisis stems from a February 2026 war between Iran and a joint US-Israeli military campaign, which escalated a 2025 conflict that devastated Iranian infrastructure. A ceasefire was formalised via a Memorandum of Understanding (MOU) signed by President Trump and Iranian President Masoud Pezeshkian on 17 June 2026 [eyeondiplomacy.substack.com](https://eyeondiplomacy.substack.com/p/the-dollar-iran-doesnt-need-why-a). This MOU set a 60-day clock for negotiations on Iran's nuclear program, the Strait's status, and sanctions.

Concurrent to this, the UN reimposed sanctions on Iran in September 2025 after Britain, France, and Germany triggered the JCPOA's 'snapback' mechanism over non-compliance—a move disputed by China and Russia but treated as binding by the US and Europe. Against this backdrop, Iran established the PGSA in May 2026 to administer the strait and levy a 5-7% cargo value fee. The US response was the SDN designation of the PGSA on 27 May 2026, followed by guidance (SB0507) confirming that crypto or yuan payments do not evade sanctions [hormuztoll.com](https://hormuztoll.com/news/2026/06/14/sanctioning-the-collector/).

## The bigger picture

**Economic — Sanctions vs. Commercial Viability**

The PGSA designation creates a 'bifurcation' where the strait is 'open' in diplomatic text but 'closed' in commercial fact. The Lloyd’s Market Association has terminated insurance for vessels paying transit fees. Since global shipping relies on dollar-based financing and Western insurance, the 5-7% fee sought by Iran becomes impossible to pay lawfully under the current OFAC regime [hormuztoll.com](https://hormuztoll.com/news/2026/06/14/sanctioning-the-collector/).

→ Sanctions exposure overrides payment method, paralyzing global shipping insurance and finance.

**International — US Hegemony and the Global Commons**

The US action asserts extraterritorial reach over a global common. While the MOU promises reopening, the US insists on stripping the PGSA of its role or lifting the designation. The GCC, the operator class, and the IMO have rejected IRGC administration of the chokepoint, highlighting the tension between Iranian sovereignty and international navigation rights under UNCLOS.

→ US secondary sanctions challenge the traditional concept of freedom of navigation in global chokepoints.

**Political — Diplomatic Text vs. Institutional Reality**

The June 2026 MOU creates a contradiction: it seeks to reopen the strait while the US has sanctioned the administrator (PGSA). The US Treasury's SB0507 guidance explicitly states sanctions apply 'regardless of payment method' [hormuztoll.com](https://hormuztoll.com/news/2026/06/14/sanctioning-the-collector/). This forces a choice: replace the PGSA with a civilian body (Suez model) or lift the designation, creating a political dilemma for the administration.

→ Diplomatic agreements are hollow if the implementing institutions remain sanctioned.

**Historical — Snapback and the JCPOA Architecture**

The current sanctions sit atop the September 2025 UN 'snapback' triggered by France, Germany, and the UK due to Iranian non-compliance with the JCPOA. Although China and Russia dispute the legitimacy of this snapback, it remains the legal basis for US and European pressure. This historical layer explains why a simple 'waiver' like General License X is temporary and doesn't undo the underlying legal structure [eyeondiplomacy.substack.com](https://eyeondiplomacy.substack.com/p/the-dollar-iran-doesnt-need-why-a).

→ Current tensions are rooted in the 2025 JCPOA snapback, not just the 2026 conflict.

## The big debate

**Should the US lift the SDN designation on the PGSA to facilitate the June 2026 Hormuz reopening MOU?**

**For**
- Lifting the designation is necessary to match diplomatic intent with commercial reality, allowing the 60-day MOU to succeed.
- A civilian administration model for the strait, similar to the Suez Canal Authority, ensures stability and global trade flow.
- Continued sanctions on the collector will keep insurance premiums high and oil supply constrained, hurting the global economy.

**Against**
- Lifting the designation legitimises an IRGC instrument, contradicting the US compliance posture built since April 2026.
- The Treasury guidance confirms that payment method (crypto/yuan) does not evade sanctions; the entity itself is the risk.
- The GCC, IMO, and global operators have already rejected IRGC administration of the chokepoint on security grounds.

**The balanced take:** The impasse requires an institutional solution: replacing the PGSA with a neutral, civilian body. This satisfies US security concerns while allowing the MOU's commercial reopening, avoiding the choice between legitimising the IRGC or stalling the deal.

## Answer it in Mains

**Discuss the implications of unilateral sanctions on global commons like the Strait of Hormuz, with reference to recent US designations.** *(GS2)*

How to attack it: Introduce the PGSA designation and the 2026 MOU. Analyse the tension between US extra-territorial sanctions and freedom of navigation. Conclude with need for multilateral mechanisms like UNCLOS.

- **[Data]** Strait of Hormuz transports roughly 20% of global oil; Iran seeks 5-7% cargo value as transit fee. — *5-7% is the fee demand; 20% is the oil flow stat.*
- **[Body/Institution]** Lloyd’s Market Association clause terminates insurance for vessels paying Hormuz transit fees to PGSA. — *Insurance is the 'invisible' bottleneck in shipping sanctions.*
- **[International]** MOU signed by Trump and Pezeshkian on 17 June 2026 set a 60-day negotiation window [eyeondiplomacy.substack.com](https://eyeondiplomacy.substack.com/p/the-dollar-iran-doesnt-need-why-a). — *60-day clock is a key timeline for current affairs.*

## What should happen

1. **Replace PGSA with a neutral civilian authority** Transitioning from a military-security body to a civilian one aligns with the Suez/Panama model accepted globally. *(Suez Canal Authority model)*
2. **Issue specific OFAC exemptions for transit fees** Creating a narrow carve-out for 'service fees' separate from IRGC funds would allow commercial transit.
3. **Formalise the 60-day MOU into a UN-backed resolution** A new UNSC resolution could terminate the 2025 snapback sanctions legally, providing certainty to banks. *(UN Security Council)*
4. **Establish a multi-national escrow for transit fees** Holding fees in a third-party account ensures Iran gets revenue without violating direct sanctions.
