**Summary**: Fresh details confirm Saudi Arabia’s key East–West pipeline remains shut after drone attacks, threatening up to 4% of global crude supply if flows are not restored within days. With Yanbu export hub stocks only offering short‑term cover, markets will price in an elevated Middle East disruption premium, especially given simultaneous tensions around the Strait of Hormuz.

## Detail

New reporting specifies that Saudi oil exports equivalent to up to 4% of global supply are at risk if the country’s damaged East–West pipeline (Petroline) does not restart within days. The line, normally carrying about 4 million barrels per day from eastern fields to the Red Sea port of Yanbu, is currently shut after drone attacks. While existing inventories at Yanbu can temporarily maintain loadings, they are finite; a multi‑day to multi‑week outage would begin to curtail actual export availability.

The immediate supply-side impact is twofold. First, there is a direct risk of lost seaborne exports via the Red Sea once Yanbu stocks draw down. Second, with the pipeline offline, Saudi Arabia becomes more dependent on Gulf export terminals and, by extension, on safe passage through the Strait of Hormuz. This concentrates route risk at a time when Hormuz has already seen a vessel hit and explicit Iranian linkage of strait reopening to U.S. policy concessions. Even if Saudi production volumes are not yet cut, the effective flexibility of Saudi export logistics is materially reduced, which is what the market will price.

The primary assets affected are Brent and WTI crude, Middle East crude benchmarks (Dubai/Oman), time spreads, and freight rates on both Red Sea and Gulf routes. Directional bias is firmly bullish for flat price and for prompt spreads, with a likely steepening of backwardation if the outage persists beyond a few days. Risk premia should also widen in related FX (stronger USD vs. high‑beta petro FX if risk sentiment deteriorates) and in regional sovereign CDS.

Historically, drone and missile attacks on Saudi infrastructure (e.g., Abqaiq–Khurais in 2019) have produced multi‑percent intraday spikes in Brent as traders reassessed both immediate supply loss and the vulnerability of critical assets. While current information points to a logistics bottleneck rather than physical field damage, the potential 4% at‑risk figure is large enough to justify a >1% move in major crude benchmarks.

If repairs restore flows within several days, the impact will be significant but transient, with some unwinding of the spike. A prolonged outage (weeks) or further attacks would shift this from a short‑term logistics shock to a structural risk-premium repricing, with sustained upside pressure on crude and refined product cracks.

**AFFECTED ASSETS:** Brent Crude, WTI Crude, Dubai Crude, Gasoil futures, Arab Light OSPs, Oil tanker freight rates (Red Sea, Persian Gulf), Saudi CDS, Energy equities (IOCs, NOCs, oilfield services)
