Baghdad's confirmation narrows the attribution question on the attack that took the pipeline offline, while the International Energy Agency reports Saudi crude supply at its lowest in more than three decades.
Iraq's Prime Minister's Office said on Sunday that its investigation confirmed the drones used in the attack on Saudi Arabia's East-West pipeline were launched from Maysan Governorate in southern Iraq.
That is a narrower and more consequential statement than it first appears. It is an official government finding on the origin of the attack, replacing several days of analyst inference. It does not name a responsible group, and it does not establish a chain of command. The attribution question is tighter than it was on Friday. It is not closed.
The pipeline itself has been offline since drone strikes on . It carries crude across Saudi Arabia from the eastern producing region to the Red Sea terminal at Yanbu, which is the route that exists specifically so that Saudi exports do not have to pass through the Strait of Hormuz. With it down, the workaround is gone. Yanbu's storage is reported to cover only five to seven days of throughput, and as much as 4% of global oil supply sits behind the outage.
Aramco has disclosed no reopening timeline and no quantified production or export impact. That absence is now the central unresolved fact in the entire oil complex, and it has been unresolved for five days.
The supply number
The International Energy Agency has reported that Saudi crude supply fell to its lowest level in more than three decades. That is a striking figure, and how the comparison is drawn matters. A crude-only measure and a crude-plus-condensate measure produce different answers, as do a monthly average and a spot reading, and the figure has been quoted without specifying which. The direction is unambiguous. The precise comparison is not.
A prior restoration is not a forecast
The same pipeline was attacked and restored earlier this year, with throughput returning to roughly 7 million barrels a day in April. It is tempting to read that episode as a timeline for this one. It should not be. Different attack, different damage, different repair. The April episode is useful only as evidence that this asset is repeatedly targeted and that Saudi Arabia has restored it before.
What to watch
The disclosure that would move this market most is not another diplomatic development. It is Aramco or the Saudi Ministry of Energy putting a date on the pipeline's return, or a number on what the outage has cost in export volume. Until one of those exists, the market is pricing an outage of unknown duration, which is the most expensive kind.
