Oil prices extended their advance on Tuesday, with Brent crude hovering near $107 a barrel and West Texas Intermediate above $102, as attacks on Saudi energy infrastructure underscored the fragility of key Middle East export routes. The latest disruption—a shutdown of Saudi Arabia's East-West pipeline—has shifted market focus from demand worries to the physical availability of barrels.
Pipeline outage removes a crucial escape route
The East-West pipeline, which carries crude from Saudi Arabia's eastern fields to the Red Sea port of Yanbu, was closed after a drone attack blamed on Iran-backed militias in Iraq. Regional officials indicated repairs could take three to five weeks. According to Rystad Energy, the pipeline had been moving between 2.6 million and 4 million barrels per day since late August—at the upper end, roughly 4% of global supply.
Janiv Shah of Rystad Energy told AP that the jump in Brent already reflects a meaningful loss of supply, and cautioned that Saudi inventories can cushion exports only temporarily if the outage persists.
Shipping bottlenecks tighten the physical market
The pipeline shutdown would be less disruptive if alternative routes were operating normally, but they are not. Traffic through the Strait of Hormuz remains far below pre-war levels, while Houthi pressure around Bab el-Mandeb threatens another major passage linking the Red Sea with global markets. Melius Research estimated that about 3 million barrels per day moved through Bab el-Mandeb in early September, but told AP that flows may now be effectively zero.
The result is not simply a geopolitical risk premium. It is a logistics problem that can raise freight costs, delay cargoes, and force refiners to compete more aggressively for available barrels. Vivek Dhar of Commonwealth Bank of Australia told The Wall Street Journal that Chinese crude imports are rising while meaningful new non-OPEC+ supply outside the Middle East may not arrive until 2027. He also sees an increasingly plausible scenario in which global oil and refined-product inventories provide only five to 11 weeks of cover.
Oil above $100 raises a wider inflation problem
The squeeze is already spreading beyond crude futures. US diesel averaged a record $6.23 a gallon on Monday, showing how disrupted energy flows can quickly feed into transport and production costs. Melius Research analysts told AP that an inflationary spillover is becoming increasingly likely, particularly with the US harvest and heating seasons approaching.
WTI's move above the high-$90s leaves momentum tilted higher, with the previous cycle peak around $107 a key technical reference. But the bigger question is now physical rather than technical: how quickly Saudi Arabia can restore its pipeline, and whether enough crude can safely move through Hormuz and the Red Sea in the meantime.
For investors, the episode highlights the limits of Saudi Arabia's Plan B—the strategy of using spare capacity and alternative routes to offset disruptions. With the East-West pipeline down and Hormuz traffic constrained, the kingdom's ability to guarantee supply is being tested. As Brent hits $107.66, the market is pricing in a prolonged period of tightness. Meanwhile, the US has surpassed Saudi Arabia and Russia as the top oil exporter, a shift that could provide some buffer but not enough to offset Middle East disruptions.
With gold holding near $4,300 as the Fed decision looms, oil's rise adds another layer of complexity to the inflation outlook. The coming weeks will be critical in determining whether the pipeline can be repaired quickly or whether the market must adapt to a longer-term supply squeeze.
