Global crude prices declined on Wednesday as Saudi Arabia rerouted oil shipments through Oman following drone strikes that damaged its critical East-West pipeline. The workaround eased immediate supply fears, though diesel markets remained near record highs amid ongoing Middle East tensions and tightened Russian exports.
Oil markets reacted quickly on Wednesday, September 16, 2026, to alternative shipping arrangements in the Middle East following drone attacks that damaged a major Saudi pipeline connecting eastern production facilities to the Red Sea. Brent crude futures fell 83 cents, or 0.76%, to $107.92 a barrel by 08:01 GMT, while U.S. West Texas Intermediate futures dropped $1.41, or 1.33%, to $104.42 a barrel, according to market data.
The pullback followed a steep two-day rally. Both major benchmarks had surged more than $3 in the previous session after shipping industry sources confirmed that crude loading operations at Saudi Arabia’s Yanbu export hub were suspended and that Riyadh had canceled several cargo deliveries scheduled for European customers.
Ship-to-Ship Transfers Off Oman Ease Red Sea Disruptions
To offset the loss of its key land bridge to the Red Sea, Saudi Arabia began offering additional crude cargoes to Asian refiners through ship-to-ship transfers near Oman’s Sohar port, according to people familiar with the arrangements cited by energy reporting platforms. This swift tactical response helped calm traders who feared a prolonged and total constraint on Saudi export volumes.
UBS analyst Giovanni Staunovo noted that the reports of Saudi exports through the Gulf suggested that concerns about the potential scale of the disruption were easing.
Before the pipeline attacks, Yanbu had served as Saudi Arabia’s primary alternative export outlet because maritime traffic through the Strait of Hormuz faced persistent security threats. Preliminary shipping data showed only four visible vessel transits through the Strait of Hormuz on Tuesday, down from seven on Monday and well below the 10-day average of 18.
The Strategic Vulnerability of Saudi Arabia’s East-West Pipeline
Janiv Shah, vice president of oil commodity markets at Rystad Energy, explained that loadings at Yanbu had functioned as a vital rescue option because the kingdom relied heavily on the Red Sea route to bypass Hormuz. Without the East-West pipeline, Saudi Arabia lacks other domestic pipelines with comparable scale and capacity.
“The harsh reality is that the East-West pipeline is Saudi’s key insurance policy against the Strait of Hormuz risk. Without the East-West pipeline, Saudi Arabia loses its main land bridge from eastern oil fields to the Red Sea.”

Professor Mark Goh from the National University of Singapore Business School added that while Riyadh could tap overseas stockpiles or redirect crude to domestic refining, those options remain severely constrained by logistics and cannot provide a long-term replacement for the pipeline. Market observers estimate that oil storage at Yanbu port has fallen below 15 million barrels down from nearly 21 million barrels in July, a volume sufficient for only a few days of exports at current operational rates.
U.S. Crude Inventories and Record European Diesel Pressures
Downward pressure on oil prices was reinforced by inventory data from the United States released by the Energy Information Administration. U.S. crude inventories fell by approximately 640,000 barrels last week, a draw significantly smaller than the 1.62 million barrel reduction expected by analysts in a Reuters poll. Simultaneously, U.S. gasoline and distillate inventories rose, with diesel stockpiles recording larger-than-expected gains.
Product markets, particularly diesel, continued to reflect severe regional supply constraints. European gasoil futures settled at a record high, driven by the loss of Middle East diesel and jet fuel supply alongside ongoing disruptions at major Russian refineries due to Ukrainian attacks and extended Moscow fuel export restrictions.
Market analysts note that while alternative routing through Oman has prevented an immediate physical catastrophe, geopolitical risk premiums remain exceptionally high. As repair work continues on the damaged pipeline infrastructure, market participants continue to monitor whether regional diplomatic efforts will successfully reopen the Strait of Hormuz or if further escalation will disrupt maritime transit channels.
