## Why this matters

Strait of Hormuz controls ~20% of global oil flow; any fee or control change directly impacts India's energy security and inflation. The story tests grasp of international law, UNCLOS, and India's maritime diplomacy for GS2/GS3.

## In plain words

The Strait of Hormuz is a narrow sea lane between Iran and Oman through which about one-fifth of the world's crude oil moves every day. Because it is so narrow, whoever controls the strait can effectively decide which ships pass and which wait. For decades, Iran claimed the right to regulate passage, while the global shipping industry insisted on free transit under international law.

Now, after a brief war in 2026 and a ceasefire, Iran and Oman are negotiating a deal to reopen the strait. The proposal splits the waterway into two one-way lanes: Iran would manage ships entering the Gulf, Oman would manage ships leaving. Both countries would charge a "service fee" to pay for coastal patrols and for cleaning up oil spills that threaten coral reefs and marine life. The United States objects, arguing that any toll violates the freedom of navigation guaranteed by the United Nations Convention on the Law of the Sea.

Think of the strait like a narrow bridge on a busy highway. If the towns on each side start charging a toll to maintain the bridge and plant trees nearby, drivers may welcome the cleaner, safer crossing—but if the toll is too high or the collectors are under sanctions, most trucks will simply stop using the bridge.

## Key facts

- Service fees under the emerging deal will fund security provisions and maritime environmental preservation in the Strait of Hormuz.
- Strait of Hormuz is a critical chokepoint for ~20% of global oil supplies and other vital cargo.
- Deal proposes separate Iran-controlled inbound routes and Oman-controlled outbound routes for shipping.
- Fee structure remains a key contention point, with the US demanding toll-free passage for commercial vessels.

## How we got here

The Strait of Hormuz has been a flashpoint since the 1980s "Tanker War," when Iraq and Iran attacked each other's oil shipments. In 1982, the United Nations Convention on the Law of the Sea (UNCLOS) set rules for transit passage, allowing ships to pass quickly without paying tolls, though coastal states can charge for specific services like pilotage. In February 2026, a joint U.S.-Israeli military campaign escalated into a wider conflict with Iran, damaging infrastructure and disrupting shipping. A temporary ceasefire in April 2026 left about 2,000 vessels stranded, carrying roughly 21 billion litres of oil, according to CNN reporting. On June 17, 2026, U.S. President Trump and Iranian President Pezeshkian signed a Memorandum of Understanding (MOU) to negotiate a permanent settlement within 60 days. Iran's parliament then passed legislation imposing a transit fee of about $2 million per voyage. Meanwhile, the U.S. Treasury's Office of Foreign Assets Control (OFAC) had designated the Persian Gulf Strait Authority (PGSA) as a Specially Designated National (SDN) on May 27, 2026, complicating any deal that uses that body as the fee collector.

## The bigger picture

**International — UNCLOS vs. Sovereign Control**

Under UNCLOS Article 26, coastal states may charge only for specific services rendered, not a general toll for passage. Iran's proposed $2 million fee per voyage, reported by Eye on Diplomacy, tests this limit. The U.S. insists on toll-free transit, while Iran argues the fee funds security and environmental protection. The PGSA, designated as an SDN entity by OFAC on May 27, 2026, cannot lawfully receive dollar payments, forcing negotiators to consider a civilian body.

→ International law permits service fees but prohibits arbitrary tolls; sanctions on the collector create a compliance hurdle.

**Economic — Energy Security and Shipping Costs**

About 20% of global oil transits Hormuz. During the 2026 crisis, over 150 vessels were anchored or delayed, leaving 120–150 million barrels idle—equal to six‑seven days of normal throughput, per GoMarkets data. A new fee, even if called a service charge, could raise freight rates and insurance premiums, ultimately affecting oil prices in importing countries like India.

→ Any fee increases shipping costs, potentially raising India's import bill and inflation.

**Environmental — Marine Ecosystem Protection**

The strait sits between the warm Persian Gulf and the cooler Gulf of Oman, creating a nutrient-rich transition zone that supports coral reefs, plankton blooms, whale sharks, dolphins and turtles, as documented by CNN. Oil spills and anchor damage from stranded ships threaten this biodiversity. The proposed fee aims to fund coastal patrols and spill-response, aligning with SDG 14 (Life Below Water).

→ Revenue earmarked for environmental protection could mitigate ecological damage from heavy tanker traffic.

**Political — Geopolitical Realignment in West Asia**

The deal envisions Iran controlling inbound lanes and Oman outbound lanes, a division that reflects Oman's traditional mediator role. The U.S. MOU of June 17, 2026, seeks a permanent settlement covering Hormuz, Iran's nuclear program and sanctions. However, the UN snapback sanctions reimposed in September 2025 remain formally in force, limiting how quickly the PGSA can be delisted.

→ The proposed split governance mirrors Oman's balancing act between Iran and the West.

## The big debate

**Should the Strait of Hormuz impose service fees for security and environmental protection, or must passage remain entirely toll-free?**

**For**
- Fees can fund coastal patrols and rapid oil-spill response, protecting the fragile marine ecosystem.
- A transparent, service-cost tariff through regulated banks satisfies UNCLOS Article 26 and ensures accountability.
- Revenue sharing between Iran and Oman promotes regional cooperation and stabilises the waterway.

**Against**
- Any fee, even if labelled a service charge, sets a precedent for taxing global commons and raises shipping costs.
- The designated collector, PGSA, is an SDN entity; operators risk sanctions if they pay, making the deal commercially unviable.
- The U.S. and GCC reject IRGC-linked administration of the chokepoint, viewing tolls as coercive leverage.

**The balanced take:** A carefully calibrated service fee that is civilian-administered, SDN-compliant, and limited to actual costs can reconcile environmental needs with free transit. However, unless the collector is delisted or replaced, the deal remains a diplomatic text with little commercial effect.

## Answer it in Mains

**Discuss the implications of the proposed Iran-Oman deal on the Strait of Hormuz for regional stability and global energy security.** *(GS2)*

How to attack it: Introduce the strait's strategic importance, outline the deal's inbound-outbound split, analyse UNCLOS provisions, then examine geopolitical reactions and India's energy interests.

Quote this: Cite UNCLOS Article 26, OFAC SDN designation of PGSA (27 May 2026), and the June 2026 MOU between Trump and Pezeshkian.

**How can environmental concerns be balanced with the principle of freedom of navigation in critical maritime chokepoints?** *(GS3)*

How to attack it: Explain the ecological sensitivity of Hormuz, describe the proposed service-fee model, contrast with UNCLOS transit passage, and suggest a cooperative funding mechanism.

Quote this: Reference CNN report on marine species (dolphins, turtles, whale sharks) and SDG 14 as a normative framework.

**The Strait of Hormuz is not merely a waterway but a geopolitical lever. Critically examine this statement in light of recent developments.** *(Essay)*

How to attack it: Open with the 2026 crisis, discuss the weaponisation of transit through fees and sanctions, analyse the dollar-yuan dimension, and conclude with the need for multilateral governance.

Quote this: Use the $2 million fee per voyage and the General License X (23 June 2026) to illustrate the intersection of finance, sanctions, and geography.

## Prelims quick-fire

- **[Geography]** Strait of Hormuz connects Persian Gulf to Gulf of Oman; ~20% of global oil transits here (GoMarkets 2026). — *Often asked as a map-based question; remember it lies between Iran and Oman.*
- **[International]** UNCLOS Article 26 permits coastal states to charge fees only for specific services, not general passage tolls. — *Distinguish Article 26 (service fees) from Article 38 (right of transit passage).*
- **[Body/Institution]** OFAC designated the Persian Gulf Strait Authority (PGSA) as an SDN on 27 May 2026 (HormuzToll). — *SDN = Specially Designated National; means U.S. persons cannot deal with the entity.*
- **[International]** UN snapback sanctions on Iran were triggered in September 2025 by UK, France, Germany (Eye on Diplomacy). — *Snapback mechanism is part of JCPOA; China and Russia dispute its legitimacy.*
- **[Data]** During April 2026 crisis, ~2,000 vessels carrying 21 billion litres of oil were stranded (CNN). — *Use to illustrate scale of disruption; 21 billion litres ≈ 132 million barrels.*
- **[International]** General License X issued 23 June 2026 authorises dollar payments for Iranian oil until 21 August 2026. — *License is temporary, tied to the 60-day MOU window; not a permanent lifting of sanctions.*
- **[Data]** Iran's parliament passed legislation imposing ~$2 million transit fee per voyage (Eye on Diplomacy 2026). — *Fee is per voyage, not per barrel; meant for security and environmental purposes.*

## What should happen

1. **Replace the PGSA with a joint civilian authority including Oman, as suggested by HormuzToll analysis.** A non-sanctioned body would allow global operators to pay lawfully through the regulated banking system. *(hormuztoll.com)*
2. **Align any fee strictly with UNCLOS Article 26 service-cost principles and publish the rate schedule.** Transparency prevents the fee from being seen as an arbitrary toll and reduces legal challenges. *(UNCLOS)*
3. **Use part of the revenue for a dedicated marine-spill response fund covering the Persian Gulf and Gulf of Oman.** This directly addresses the environmental dimension and supports SDG 14 targets. *(SDG 14)*
4. **Secure a parallel OFAC general license that explicitly authorises dollar payments to the new civilian collector.** Without such a license, banks and insurers will continue to treat transactions as high-risk. *(General License X)*

## Jargon, demystified

- **UNCLOS (United Nations Convention on the Law of the Sea)** — A 1982 treaty that sets legal framework for all ocean uses, including rules for transit passage and service fees in straits. *(Article 26 is key for service fees; Article 38 for transit passage.)*
- **SDN (Specially Designated National)** — A list maintained by U.S. OFAC of individuals and entities with whom U.S. persons are prohibited from dealing. *(PGSA was added to SDN list on 27 May 2026, blocking dollar transactions.)*
- **PGSA (Persian Gulf Strait Authority)** — An Iranian body proposed to administer shipping in Hormuz; currently designated as an SDN entity by the U.S. *(Central to the 'collector' controversy; replacing it with a civilian body is one solution.)*
- **OFAC (Office of Foreign Assets Control)** — A division of the U.S. Treasury that enforces economic sanctions and maintains the SDN list. *(Issued General License X on 23 June 2026 authorising dollar oil payments.)*
- **MOU (Memorandum of Understanding)** — A formal agreement between parties that outlines intentions and plans, but is not a legally binding treaty. *(The 17 June 2026 MOU set a 60-day negotiation window for Hormuz and nuclear issues.)*
- **Snapback sanctions** — A mechanism in the JCPOA allowing parties to quickly reimpose UN sanctions if Iran violates nuclear commitments. *(Triggered by UK, France, Germany in September 2025; still formally in force.)*
