The pipeline that was the world's Plan B just went dark

Saudi Arabia's East-West line is down, Yanbu has a week of oil in the tanks, and $4.31 gas may be the cheap part.

In brief

Saudi Arabia's East-West line is down, Yanbu has a week of oil in the tanks, and $4.31 gas may be the cheap part. This outage matters less for the 4 million barrels a day it moves than for what it was: the only route around the Strait of Hormuz. With it down, there is no backup left. Originally reported by Yahoo…

The main line is down

The main line is down

Houthi strikes shut Saudi Arabia's East-West pipeline over the weekend. It normally moves about 4 million barrels a day to the Red Sea port of Yanbu, roughly 4% of global supply.

“The single most important pipeline in global oil trade is offline”

Five to seven days

Tanks already sitting at Yanbu can keep tankers loading for 5 to 7 days. Egypt's Ain Sukhna and Sidi Kerir terminals add a few more. One source told Reuters repairs could run five to six weeks.

It hit a weak market

Saudi output had already slid to 6.2 million barrels a day in August, down from 10.9 million in February. The IEA expects global supply to fall 5.7 million barrels a day this year, about 6%.

The world lost its Plan B

The East-West line matters more than its volume suggests. It is the workaround for the Strait of Hormuz, which has been disrupted on and off for months. Take out the workaround and nothing is left behind it.

“Take out the workaround, and the world loses its Plan B.”

Brent went vertical

Brent settled at $109.51 on September 9, up from $87.77 on August 26. WTI closed at $97.26 after starting July near $69.74. Both sit above $100 now.

Nobody has spare barrels

The EIA cut its OPEC spare capacity forecast to 2.5 million barrels a day for 2027, down from 3.8 million. There is no obvious idle barrel waiting to fill the hole.

“There is no obvious replacement barrel sitting idle.”

It spreads past the pump

Gas is $4.31 a gallon, above the EIA's $4.00 pain threshold. August CPI rose 0.4%, the 10-year Treasury hit 4.95%, and sentiment sits at 55.2. Diesel prices feed food, freight, and anything on a truck.

What to watch next

An Aramco or energy ministry statement on restart timing is the signal. Silence past day seven means open-ended. Also watch for an SPR release and any OPEC+ move on unwinding cuts.

“$4.31 gasoline will look cheap by Halloween.”

The short version

This outage matters less for the 4 million barrels a day it moves than for what it was: the only route around the Strait of Hormuz. With it down, there is no backup left.
