THE BOTTLENECK
Hormuz is 33 km wide at its narrowest, with shipping lanes just 3 km in each direction. Roughly 21 million barrels of oil pass through daily — about 21% of global consumption — and the deepest channel hugs the Iranian coast.
THE PIPELINE'S ORIGINAL PURPOSE
The East-West Pipeline — Petroline — was built in 1981 during the Iran-Iraq War, when Tehran threatened Gulf shipping. Saudi Arabia ran a 1,200 km line from Abqaiq to Yanbu on the Red Sea, designed for exactly the contingency that has now arrived.
WHY ALTERNATIVES ARE LIMITED
Saudi Arabia's East-West Pipeline and the UAE's Habshan-Fujairah line together can move roughly 6.5 million barrels a day around Hormuz — less than a third of normal flow. There is no pipeline solution at all for Qatari LNG, Kuwaiti crude, or Iraqi southern exports.
THE SPARE CAPACITY MATH
Saudi Arabia holds most of the world's spare capacity — the volume producers can bring online within 90 days. Cutting 2 million barrels a day in a crisis is not a sacrifice; it is the cushion vanishing. Once spare capacity drops below 2m bbl/day, any further disruption moves prices exponentially, not linearly.
THE 2019 PRECEDENT
In May 2019, Houthi drones struck two Petroline pumping stations 320 km west of Riyadh. Months later, cruise missiles and drones hit Abqaiq — the processing complex that feeds the pipeline — knocking out 5.7 million barrels a day for weeks. The bypass infrastructure is itself a target.
THE PRICE FLOOR
Aramco's $32.5 billion quarter signals what the producers gain when chokepoints close: scarcity rents flow to the seller with the only working route. Saudi Arabia is simultaneously the country most exposed to Hormuz disruption and the country with the most to gain from it staying disrupted just long enough.
