The Pipe Came Back

> Saudi Arabia restarted the pipeline that carries its oil around the Strait of Hormuz, and the oil price fell more than two dollars on the news. The terminal at the other end has loaded nothing since 11 September. What the restart actually buys depends on which of two things stopped the cargoes, and the evidence now points both ways.

On 10 September drones flew out of Maysan province in southeastern Iraq and struck the East-West Pipeline in the Riyadh and Medina areas. The Saudi Energy Ministry stopped the line the next day as a precaution. That pipe had been moving between four and five million barrels a day across the country to Yanbu on the Red Sea, close to five percent of world supply, and it was the kingdom's answer to a Strait of Hormuz that shippers have spent months avoiding.

On 22 September Riyadh restarted it. Brent fell more than two dollars a barrel to its lowest since 8 September.

The line is pumping at a low rate. Tanker trackers record no crude loading at Yanbu since 11 September, the day the pipe stopped. Multiple pumping stations were disabled while the pipeline itself came through largely intact, and Aramco is building a bypass around the damaged sections. Full repairs run four to six weeks on the best current estimate. That bypass should carry around two to two and a half million barrels a day within about a month, roughly half of what Yanbu was shipping before the drones arrived.

The announcement moved the price. The cargoes have yet to move at all.

There is a reason the market took the restart at face value. In April a pumping station on this same line was hit and output fell to 700,000 barrels a day. Three days later Saudi Arabia announced full capacity restored. That figure has been doing quiet work in everyone's assumptions ever since. It describes a line that kept running while crews repaired it. September shut the line to zero, and a repair clock measured against a press release will always flatter itself.

Two explanations fit the eleven days, and they point at different futures.

The first is mechanical. Disabled pumping stations stop oil reaching the coast, the coast is otherwise fine and Yanbu resumes when the bypass is welded. On this reading the loading halt began the day the pipe stopped because the pipe stopping is the entire cause. The tanker trackers say so directly.

The second is maritime. The Houthis declared an embargo on Saudi vessels in July and hold Mocha, Mayyun Island and the Yemeni approaches to Bab al-Mandab. They claim attacks on an Aramco facility at Yanbu itself. They damaged an Italian Eurofighter at a Saudi air base on 17 September. Chinese refiners had already stopped lifting from Yanbu in August over precisely this risk, well before any drone reached the pipeline. On this reading the pipe is the easy half, and a full terminal changes nothing that a tanker captain weighs.

Aramco has told at least three Asian refiners informally that Yanbu cargoes will be liftable soon. That is the seller talking. The buyers have not answered anywhere visible.

The figure that separates these readings is a loaded cargo at Yanbu with a destination. One tanker filling and sailing settles it for the mechanical case. Weeks of a repaired line feeding a quiet berth settles it for the other. Riyadh is meanwhile selling more Gulf barrels into China and South Korea, which holds for as long as ships keep crossing a strait that carried seventeen of them last weekend against a pre-war norm near 125 a day.
