A Toll on a Strait Nobody Owns: The 20% Hormuz Fee That Lasted a Day
The proposal was withdrawn within twenty-four hours, but it priced India's exposure precisely — 90% of LPG, 60% of LNG and 40% of crude pass through one channel
What happened
The fee was withdrawn, so the temptation is to treat it as a non-event. The opposite is true: a proposal that never took effect produced the clearest available quantification of Indian vulnerability, and a clean test of whether the law of the sea holds when a great power tests it. Learn the legal rule and the arithmetic together — transit passage is the doctrine, and $2 billion per dollar per barrel is what it protects.
How Much of India's Energy Passes Through One Channel
Share of Imports Transiting the Strait of Hormuz
| Crude imported annually | 1.8–2 bn barrels |
| Cost of every $1/barrel move | ~$2 billion |
| Estimated cost of a 20% fee | ~$9 billion/yr |
| Oil imports, Mar–May 2026 | $48.88 bn (+47% YoY) |

The Strait of Hormuz connects the Persian Gulf to the Gulf of Oman and the Arabian Sea, bounded by Iran to the north and Oman and the UAE to the south.
●It is the world's most important oil transit chokepoint.
●Legally it is governed by Part III of the United Nations Convention on the Law of the Sea (UNCLOS), 1982, which establishes the regime of transit passage through straits used for international navigation: ships and aircraft enjoy continuous and expeditious passage, which coastal states shall not impede, and no charges may be levied merely for passage.
●This is distinct from innocent passage through the territorial sea, which may be suspended in certain circumstances; transit passage cannot.
●The regime is widely regarded as customary international law, and therefore binding on states that have not ratified UNCLOS — a category that includes both the United States and Iran.
●The International Maritime Organization's position aligns with UNCLOS. India's exposure is concentrated: about 40 per cent of crude oil, 60 per cent of LNG and 90 per cent of LPG imports come from West Asia through this channel, against overall import dependence of roughly 88 per cent for oil, 60 per cent for LPG and about half for natural gas.
●Pre-conflict vessel transits ran up to 140 a day.
Transit passage is not a privilege granted by the littoral states — it is a right that survives their objection, which is why a toll on Hormuz was legally stillborn regardless of who proposed it.
◎ In Simple Words
The Strait of Hormuz is a narrow sea passage in West Asia through which a large share of the world's oil and gas is shipped. Someone suggested charging ships 20 per cent of their cargo value to pass through it, then dropped the idea a day later. For India this mattered a great deal, because almost all of its cooking gas imports and much of its oil and LNG travel through that one channel. The law of the sea says ships have a right to pass through international straits freely and cannot be charged tolls — no country owns the water in the middle.

2. Coastal states may levy charges on vessels solely for the exercise of transit passage.
3. It is widely regarded as customary international law.

Frequently Asked
· People also askWhat was the proposed Hormuz transit fee?
A 20 per cent charge on commercial vessels transiting the Strait of Hormuz, announced by the US President as a reimbursement fee and withdrawn within a day, to be replaced by trade and investment arrangements. It was legally unworkable from the outset.
GS2 · IRPart III of UNCLOS guarantees transit passage through international straits, which cannot be impeded or charged for — a rule regarded as customary international law and therefore binding even on states that have not ratified the Convention.
SOURCE Outlook India; UNCLOS
How dependent is India on the Strait of Hormuz?
Heavily and unevenly. About 40 per cent of India's crude oil, 60 per cent of its LNG and 90 per cent of its LPG imports transit the Strait. Overall import dependence is roughly 88 per cent for oil, 60 per cent for LPG and around half for natural gas.
GS2 · GS3LPG is the binding vulnerability: crude is fungible and can be re-sourced at a freight penalty, but LPG has a narrower supplier base, long-term contracts and terminals configured for particular origins.
SOURCE Petroleum Planning and Analysis Cell
What would the fee have cost India?
Assuming 30 per cent of oil imports continued through the Strait, roughly $9 billion a year on the oil import bill alone — before any effect on LNG, LPG, fertilisers and industrial inputs. Every $1 per barrel movement costs India about $2 billion.
GS3 · EconomyIndia imports between 1.8 and 2 billion barrels of crude annually, and imports had already risen 47 per cent year on year to $48.88 billion over March to May 2026, so the base on which any shock would operate was already elevated.
SOURCE Trade and petroleum data, 2026
What is transit passage and how does it differ from innocent passage?
Transit passage applies to straits used for international navigation: ships and aircraft enjoy continuous and expeditious passage that coastal states shall not impede or suspend. Innocent passage applies to the territorial sea and may be suspended in defined circumstances. Only transit passage is non-suspendable.
GS2 · IRThat distinction is what makes a toll on Hormuz legally impossible rather than merely contested — no charge may be levied for the exercise of transit passage.
SOURCE UNCLOS, 1982, Part III
Does UNCLOS bind the US and Iran if they have not ratified it?
On this point, yes. The transit passage regime is widely regarded as customary international law, which binds states independently of treaty ratification. Neither the United States nor Iran has ratified UNCLOS, yet neither can lawfully levy charges on passage through an international strait.
GS2 · IRThe International Maritime Organization's position aligns with UNCLOS, and India has consistently advocated that navigation through international waterways remain free and accessible to all.
SOURCE UNCLOS; International Maritime Organization
What can India do to reduce this exposure?
Three tracks on different horizons: immediate sourcing diversification and strategic petroleum reserves; medium-term domestic substitution, notably compressed biogas for the heavily Hormuz-dependent LPG; and long-term electrification of cooking and transport, which removes the exposure rather than hedging it.
GS3 · EconomyUnlike China, India has no viable overland pipeline alternative — proposed routes through Pakistan or across the Himalaya have foundered on geopolitics and terrain — leaving sea routes as effectively the only channel.
