Iran has effectively turned the world’s most critical oil shipping route into a controlled checkpoint, forcing vessels to seek clearance from the military before passing through the Strait of Hormuz.

Shipping intelligence reports say Tehran has already implemented a “de facto toll booth regime” in the strategic waterway. The move comes even as Iranian lawmakers prepare legislation to formally charge vessels for transit.

The development threatens to reshape global shipping through a chokepoint that carries roughly a fifth of the world’s oil supply.

IRGC tightens grip on the world’s busiest oil corridor

The system is controlled by Iran’s powerful Islamic Revolutionary Guard Corps navy, which now requires ships to submit documentation and obtain clearance codes before entering a controlled transit corridor.

According to maritime reports, vessels must provide ownership records, cargo details, crew lists and final destinations. The information is screened by the IRGC’s Hormozgan command for sanctions and “geopolitical vetting”.

If approved, ships receive routing instructions and an escort through Iranian territorial waters near Larak Island.

Traffic collapses as shipping lanes fall silent

The impact has been immediate. Since mid-March, dozens of vessels have used the IRGC-controlled route while traditional commercial lanes have largely emptied.

On Tuesday only four ships crossed the strait, according to maritime intelligence data. Several large vessels were seen waiting north of Larak Island, apparently queuing for authorised transit.

Others appear to be avoiding the system entirely, hugging the Omani coastline or switching off location transmitters to bypass Iranian oversight.

Some ships already paying tolls

Reports indicate that at least two vessels have paid direct transit fees, with payments settled in Chinese yuan. Many other crossings appear to have been secured through diplomatic intervention rather than cash payments.

Iranian officials argue the charges are justified because Tehran provides security in the waterway. Lawmakers say proposed legislation will formally establish Iran’s authority to collect fees from oil tankers and cargo ships.

Legal minefield for global shipping companies

The arrangement puts international shipping firms in a legal trap. The IRGC is designated as a terrorist organisation by the United States, meaning any payments could trigger criminal liability under US law.

Legal experts warn even indirect payments could be considered “material support” to a banned group. UK and EU sanctions regimes offer no protection either.

With billions in global trade at stake, security advisers say shipowners are scrambling for guidance as the strait — long treated as open international waters — risks becoming a militarised toll road.

Iran imposes 'toll booth regime' to allow Strait of Hormuz passage

Outstanding. A million dollars per ship to finance Iran's defence. Only nations not involved in supporting the US and Israel need apply. The others will be bombed.

Terroris extortion will be bombed ,the western countries faces recession otherwise

Mark Felton compares a possible US invasion of the Hormuz Strait with the attacks on Allied ships off Okinawa in 1945.

He notes the similarities of some of the weapons used by the Japanese then compared to those available to the Iranians today.

The thing is this is illegal. If companies are found to have been paying Iran, they could find themselves under sanction, essentially put out of business. They would not only be guilty of transferring funds to a sanctioned state, but also complicit in undermining international maritime rules. The tolls would be paid either to the Iranian Port Authority or to the IRGC, both of which are explicitly sanctioned organisations by the US. So they would face sanctions from the US. The EU and UK takes a different view, as they will accept such payments were made under "duress, forced for safety". Moreover, the insurers might withdraw insurance from shipping companies, because they have an absolute requirement to comply with international law. Such actions would mean these ships will be denied entry to ports worldwide, will not be able to pass through the Panama or Suez canals, may struggle to obtain bank financing, and see their charter business dry up.

UNCLOS establishes a legal right to "transit passage". This is why nations often come to near blows in the South China Sea, during FONOPS.

Sanctioned by the US, they must be quaking in their boots! They have the oil & countries are buying so <deleted> sanctions! Pay up or shut up.

Or how about this. You can use the Strait freely. But we won't sell you any oil because you're allies of the US and Israel. Sorry, we're sanctioned.
