Iran’s new Persian Gulf Strait Authority vets Hormuz transits — hours after Trump and Xi declared the strait “must remain open.” Washington demands Tehran surrender enriched uranium; Tehran demands sanctions lifted and Hormuz sovereignty recognized.

THE BOTTLENECK
Hormuz is 33 km wide at its narrowest, but the shipping lanes are just 3 km each — two inbound, two outbound, separated by a 3 km buffer. Roughly 21 million barrels of oil pass through daily, about a fifth of global consumption.
THE GEOGRAPHY OF LEVERAGE
The strait sits between Iran and Oman, not Iran and any Arab Gulf state. Iran's coastline runs along the entire northern edge, and the deepest shipping channel hugs the Iranian side — which is why Iranian naval positioning matters disproportionately to anyone else's.
THE LEGAL CLAIM
Under UNCLOS Article 38, ships have a right of transit passage through international straits — coastal states cannot suspend passage or impose conditions. Iran signed UNCLOS in 1982 but never ratified it, and has long argued Hormuz is governed by its own domestic law. A 'Strait Authority' that vets transits is the operational expression of that doctrine.
THE TANKER WAR PRECEDENT
From 1984 to 1988, Iran and Iraq attacked over 400 commercial ships in the Gulf. Oil prices spiked briefly but markets adapted — tankers were reflagged under US and Kuwaiti flags and escorted by warships. The lesson planners took then still holds: disruption is easier to threaten than to sustain.
WHY IT CAN'T BE BYPASSED
Saudi Arabia's East-West Pipeline (5 million bbl/day) and the UAE's Habshan-Fujairah pipeline together could reroute maybe a third of Gulf exports. Fujairah — where this tanker was anchored — is itself the bypass terminal. Seizing a ship there is a deliberate signal that the workaround isn't a workaround.
THE INSURANCE CHOKEPOINT
Lloyd's of London war-risk premiums — not the seizures themselves — are what actually close a shipping lane. Once premiums spike past a threshold, commercial vessels reroute or refuse charter regardless of how many ships are actually being taken. The financial chokepoint is tighter than the physical one.
