Saudi Pipeline Shutdown Exposes Vulnerabilities in Kingdom's Oil Export Strategy

Saudi Arabia's East-West Pipeline, built as a redundancy to bypass the Strait of Hormuz, has been temporarily shut down due to drone strikes attributed to Iranian-backed militias in Iraq. This forced closure threatens about 4% of global oil supplies, with Rystad Energy estimating that up to four million barrels per day moved through the pipeline as of late August.

The pipeline's importance to global oil flows is undeniable, and its vulnerability highlights the limitations of Saudi Arabia's redundancy model. The Kingdom's export network relies on several routes, including Hormuz, Bab el-Mandeb, and Suez/SUMED, but these alternatives are not entirely independent.

Data shows that while traffic through Hormuz has decreased from 21.6 million barrels per day in Q4 2025 to 4.9 million in Q2 2026, flows through the Suez Canal and SUMED pipeline have remained relatively stable at approximately 5.8 million barrels per day.

However, Saudi Arabia's ability to make use of these alternative routes depends on its ability to move crude to the Red Sea, which is critical for flexibility and scale. The East-West Pipeline and Yanbu are key nodes enabling this movement, but they themselves are vulnerable to disruption.
