Iran War Pushes Global LNG Trade into Gray Market
Miles Bennett
Four months into the US-Israeli war against Iran, Qatar is shipping LNG out of the Persian Gulf "dark" — transponders off, escorts paired — as the world's most transparent energy trade slides toward oil-market shadow tactics.
What does "going dark" actually look like?
Qatar now orders tankers to switch off AIS transponders — automated beacons that let maritime authorities track a ship's position — near Ras Laffan, the world's largest LNG export terminal, and to stay dark through the Strait of Hormuz.
Ships move in pairs, a "mini-convoy" formation: one vessel sails under a Pakistan-Iran transit agreement, the other trails it and uses the lead ship as a safety beacon through the strait.
This means → these cargoes are not smuggled; they are legitimate shipments forced to trade transparency for survival in a war zone.
How much is getting through — and does it help?
In May alone, at least four Qatari tankers slipped through the strait dark. Abu Dhabi's national oil company Adnoc moved the same number the same way.
That volume is only a fraction of pre-war flows, but for buyers like India and Bangladesh — now paying double on the spot market for replacement supply — any cargo is relief.
In plain terms = the dark shipments are a trickle, not a fix. But when prices have already doubled, every tanker that arrives matters.
Why is the LNG industry uniquely vulnerable?
LNG was long defined by high transparency: specialised ships and terminals made cargoes trackable port-to-port, underpinning the fuel's reputation for reliability.
Dark shipping dismantles that transparency directly. Asian consumers are already questioning whether LNG can still be called reliable after two supply crises in just over four years.
This reflects a deeper blow: the war is not just disrupting price and volume — it is eroding the trust architecture the entire LNG market was built on.
How did Russia's "shadow fleet" become the playbook?
The first signs of LNG dark shipping appeared in 2023, when US sanctions hit Russian gas exports. Moscow built a parallel fleet for its Arctic LNG 2 project, copying oil-industry shadow tactics to serve mainly Chinese buyers.
Neither Qatar nor Abu Dhabi is under sanctions, but analysts note both borrowed the dark-shipping playbook from Russia's experience.
This means → dark shipping has jumped from a sanctions-evasion tool to a wartime survival tool — different motive, same method, spreading across industries.
How long could this last?
MST Marquee senior energy analyst Saul Kavonic expects dark shipping to persist as long as Iran tries to control passage through Hormuz — and potentially beyond any peace deal.
Windward maritime-intelligence analyst Michelle Wiese Bockmann put it bluntly: the freedom-of-navigation foundation that global seaborne trade relies on has "suddenly ceased to exist."
In plain terms = even a ceasefire would not instantly erase the Hormuz risk premium. Once dark shipping becomes standard operating procedure, returning to the old transparent model will take a long time.
