Saudi East-West Pipeline Disruption Threatens 4% of Global Supply
Saudi Arabia's "East-West Pipeline," connecting eastern oil fields to the Red Sea port of Yanbu, was forced to shut down after being attacked by multiple drones from September 10 to 11. The pipeline has a daily transport capacity of 4 to 5 million barrels of crude oil, accounting for about 4% of global crude oil supply. Industry sources indicate that the current inventory at Yanbu can only sustain exports for 5 to 7 days.
The attacks targeted several pump stations along the pipeline, reportedly carried out by Iran-aligned militia from Iraq's southeastern Maysan province. The Iraqi Prime Minister's office confirmed this on September 13. Satellite images show black smoke along the pipeline south of Medina, and NASA detected abnormal heat signals in the area. The Saudi Foreign Ministry confirmed injuries and damage to facilities but did not disclose specific casualty figures.
This approximately 1,200-kilometer pipeline, operated by Saudi Aramco, transports crude oil from the eastern Abqaiq oil field across the country to the Red Sea port of Yanbu, bypassing the Strait of Hormuz. Saudi Arabia has temporarily closed it as a precautionary measure, with engineering teams assessing the extent of the damage. Repair timelines vary, with some sources suggesting 5 to 6 weeks, while others indicate that some sections may be repaired while partially restoring transport.
At the request of the Iraqi Prime Minister, Saudi Arabia stated it will not retaliate at this stage but reserves the right to take "all necessary measures" to protect its interests. Iraq has dismissed a military commander and condemned the attack. Analysts believe this action may have been ordered by Iran, aiming to coordinate with the objectives of the Houthi forces in Yemen, but no organization has publicly claimed responsibility.
This is not an isolated incident in the current Middle East situation. Since the outbreak of war between the U.S. and Israel against Iran in February, the Strait of Hormuz has been closed since March. The Houthi forces have continued to advance along the Red Sea coast, and Saudi crude oil production has plummeted from 10.9 million barrels per day two months before the conflict to 6.2 million barrels per day in August, the lowest level in thirty years. This pipeline disruption adds a new gap to an already significantly reduced supply.
Following the news, international oil prices briefly surpassed $100 per barrel, reaching a multi-month high, with a weekly closing increase of about 8%. Global fuel prices have surged to historical peaks, exacerbating inflation pressures in various countries, and U.S. Treasury yields have risen to their highest levels since the 2008 financial crisis. The most directly impacted are Saudi crude oil buyers reliant on the Yanbu port and Egypt's Ain Sukhna and Sidi Kerir transshipment facilities. If the pipeline is not repaired before the 5 to 7 days of inventory are exhausted, global refineries and traders will be forced to seek alternative sources from the U.S., Russia, and other origins, driving up spot premiums and freight costs.

The Saudi "East-West Pipeline" has previously been a high-value target in regional conflicts— in 2019, the Houthi forces used drones to attack facilities along this pipeline, leading Saudi Arabia to temporarily suspend some shipments. This attack occurs against the backdrop of Saudi crude oil production being halved from 10.9 million barrels per day to 6.2 million barrels per day due to the U.S.-Israel war against Iran that erupted in February this year, indicating that Saudi Arabia has repeatedly faced the dual pressure of "production capacity being forced to shrink due to regional conflicts and external transport routes being targeted" rather than a single isolated incident.
In terms of funding and resources, this supply disruption directly impacts crude oil buyers and traders reliant on exports from Yanbu and the two Egyptian transshipment ports. Once inventories are exhausted, global refineries and trading companies must urgently source supplies from U.S. shale oil, Russia, and other alternative origins, paying higher spot premiums and freight costs. Funds are effectively shifting from "stable long-term contracts" to "urgent high-priced spot purchases." Meanwhile, rising oil prices and U.S. Treasury yields reaching levels not seen since the 2008 crisis indicate that funds are also moving from risk assets to safe-haven assets, simultaneously raising global inflation pressures and interest rate hike expectations.
This aligns with previous incidents such as the 2019 attack on Saudi Abqaiq facilities, which led to a near halving of global crude oil supply, and the 2022 energy crisis in Europe triggered by the Russia-Ukraine conflict, both of which belong to the same category of "critical node attacks leading to global price reassessment." The commonality is that the attack targets are precisely chosen at points of high production concentration that are difficult to replace in the short term. The current Middle East situation is in an extremely tense phase, with "multiple fronts (Iran, Yemen, Iraqi militias) applying pressure simultaneously and the Strait of Hormuz closed for half a year." The East-West Pipeline represents Saudi Arabia's last alternative route to bypass the Strait of Hormuz.
Essentially, this is a transfer of pricing power triggered by geopolitical conflict—when the Strait of Hormuz has been continuously closed since March and Saudi Arabia has become highly reliant on the East-West Pipeline as a land alternative route, whoever can control or attack this pipeline indirectly holds the pricing power over 4% of global crude oil supply. The mechanism is that the global crude oil market has long viewed Middle Eastern supply as a "high-certainty benchmark." Once this last alternative route is proven to be precisely targetable, the market will reprice the "stable supply premium" originally attributed to Saudi Arabia as a "geopolitical conflict premium." This explains why, upon the news, oil prices and U.S. Treasury yields surged simultaneously.
