According to sources familiar with the matter, Saudi Aramco has communicated to at least two European refining clients that they will not receive any crude oil allocations next month. This follows the recent attack on a critical pipeline connecting Saudi Arabia to the Red Sea. The decision is reported to apply across the board to all European buyers, disrupting the steady monthly supply these clients typically rely on through term contracts.

Saudi Aramco has not yet responded to requests for comment outside of regular business hours. The East-West Pipeline was forced to shut down last week after a drone strike. A source indicated on Wednesday that partial operations could resume within days, with full restoration expected within six weeks.

European refineries generally collect Saudi crude at Egypt's Mediterranean port of Sidi Kerir, which is connected to the Red Sea via pipeline. The pipeline outage has triggered panic buying among some of Saudi Aramco's customers. Poland's PKN Orlen has issued more than a dozen tenders since Friday in an effort to secure alternative supply barrels. According to the International Energy Agency's monthly oil market report, OECD European countries imported 577,000 barrels per day from Saudi Arabia in June.

Why is this pipeline so significant? Global supply was already stretched by months of tensions in the Strait of Hormuz, and the closure of the East-West Pipeline has delivered another blow to the market. This pipeline traverses the Arabian Peninsula for roughly 1,200 kilometers, linking Saudi Arabia's major eastern oilfields to the port of Yanbu on the Red Sea coast. Before the conflict escalated in late February, the pipeline carried only 2.8 million barrels per day, well below its capacity of 7 million barrels per day. However, following the disruption in Hormuz shipping, Saudi Aramco quickly ramped up throughput to maximum levels.

While some crude is also directed to Saudi's domestic market, exports from Yanbu have not fully compensated for the pre-war export level of around 7 million barrels per day. Still, Saudi oil exports recovered to about 4.7 million barrels per day in June, representing approximately 5% of global supply. Yanbu's export capability is vital for capping the rise in oil prices.

Even during the pipeline outage, Saudi Arabia can rely on inventories at the Yanbu terminal to load cargoes. However, Nicholas Dell, oil analyst at Energy Aspects, points out that stocks at Yanbu are nearing historical lows. He suggests Riyadh is unlikely to completely drain its storage tanks, which could further constrain export capacity from the port. Dell also warns that tightness at Yanbu could create ripple effects, leading to more delays and cancellations at Egypt's Sidi Kerir terminal. Saudi Arabia commonly ships crude through the Suez Canal to Sidi Kerir for customers to pick up.

Where to Begin: For market watchers, the immediate focus will be on the pace of repairs to the East-West Pipeline and the drawdown rates at Yanbu. The coming weeks will be crucial in determining whether these logistical pressures translate into sustained price volatility for global crude benchmarks.
