Saudi Aramco East-West Pipeline Shutdown Drives Brent to $109.44 as Saudi Exports Lose Their Hormuz Bypass

Brent crude settled at $109.44 per barrel on Monday's ICE close, up 4.83%, after Saudi Arabia shut down the East-West Crude Oil Pipeline following drone attacks on a pumping station near Riyadh and Madinah. West Texas Intermediate settled at $104.79 per barrel on Monday's CME close, up 4.74%. Monday's closes mark the highest settlements for both benchmarks since May 2026, extending a rally of nearly 9% over five trading sessions.

The Pipeline Shutdown

The East-West Crude Oil Pipeline, known as the Petroline and operated by Saudi Aramco, connects the Eastern Province near Abqaiq to the Red Sea export hub at Yanbu. Running 1,201 kilometres across the Arabian Peninsula, the system carries up to 7 million barrels per day at full capacity. Saudi Aramco ramped the Petroline to full capacity by March 2026 after US-Iran conflict severely restricted tanker traffic through the Strait of Hormuz. Saudi authorities shut the pipeline Monday following multiple drone attacks launched from inside Iraq, which damaged a major pumping station and caused fires at the facility.

Both Saudi Export Routes Now Disrupted

With the Petroline offline, Saudi Arabia has lost its only functioning bypass for Gulf crude exports. Before the shutdown, the pipeline moved approximately 5 million barrels per day to Yanbu export terminals, with the remaining 2 million barrels per day supplying domestic west coast refineries. Saudi crude that previously flowed through Yanbu must now reach markets via Ras Tanura and Jubail on the Persian Gulf, through the Strait of Hormuz, where US-Iran tensions have severely restricted tanker movements. Saudi officials have provided no restart date; sources briefed on the damage told The Washington Times that repairs could take three to five weeks.

Alberta Oil Sands Post Historic CAD Netbacks

Alberta oil sands producers are generating their highest per-barrel Canadian dollar revenues in years as triple-digit WTI prices flow through to Western Canadian Select. WCS priced at approximately $92.79 per barrel on Monday, reflecting the WCS-WTI differential of approximately US$12 per barrel forecast by the Alberta Energy Regulator for 2026. At Monday's Bank of Canada spot rate of 1.3874 CAD/USD, that translates to roughly $128.73 per barrel in Canadian dollars. Established in-situ and mining operations carry sustaining costs of $35 to $45 CAD per barrel, leaving a spread of more than $80 CAD per barrel at current WCS prices.

Suncor Energy holds the largest combined exposure through its base plant north of Fort McMurray, a 58.74% operating stake in Syncrude Canada alongside partner ExxonMobil, and the Fort Hills oil sands operation. Imperial Oil, 70% owned by ExxonMobil, produces bitumen at Cold Lake and holds a stake in Syncrude. Canadian Natural Resources operates the Horizon Mining Complex, one of the largest oil sands mines in Canada by production volume. Cenovus Energy, with its Foster Creek and Christina Lake in-situ assets, adds substantial Athabasca exposure at current prices.

From Goldman at $85 to $109 in Six Days

When Houthi forces struck Saudi Arabia's Jazan refinery and other energy sites on September 8, Goldman Sachs was still projecting year-end Brent at $85 per barrel. At that time, as Oil Authority reported, the East-West pipeline was intact and running at capacity, serving as the functional backstop for Gulf export flows. Goldman then raised its year-end target alongside HSBC and Bank of America, as covered in Oil Authority's subsequent analysis. Monday's shutdown removes the central assumption behind those revised forecasts: a functioning Red Sea bypass capable of absorbing a partial Hormuz disruption.

Analyst Views and Diplomatic Calendar

Ahmad Assiri, analyst at Pepperstone, said Monday that "should such an important pipeline disruption persist, markets will be forced to reprice crude much higher." The Iran-GCC diplomatic meeting scheduled in Muscat was postponed at the request of regional countries, with Tehran and Muscat agreeing to reschedule, according to The National. Waleed Said at GivTrade noted that an "unusually large geopolitical premium" has kept both benchmarks above $100 even as central banks maintain restrictive monetary policy. Goldman Sachs has estimated that Brent could climb above $120 per barrel if average Gulf output in 2027 remains 4 million barrels per day below pre-conflict levels, and Monday's shutdown makes that scenario more plausible.
