An analysis by The Zioneer assesses that the Houthi declaration of a 'total maritime blockade' on Saudi Arabia is aimed at disrupting the flow of approximately 4.5 million barrels of oil per day exported via the East-West pipeline to the Red Sea port of Yanbu. The report notes alternative routes for Saudi oil, including the Suez Canal and a longer route around Africa, but highlights the operational challenges.
The Zioneer has published a detailed analysis of the Houthi movement's 'total maritime blockade' declaration, assessing its primary target as the East-West oil pipeline that carries approximately 4.5 million barrels per day from the Persian Gulf to the Red Sea port of Yanbu. The analysis was released at 16:07 Jerusalem on Monday, following a rapid sequence of reports earlier today that began at 15:04 Jerusalem.
The story unfolded in quick succession: at 15:04 Jerusalem, an initial unverified report cited a Houthi military spokesman declaring a naval siege on Saudi Arabia. Minutes later, Houthi spokesman Yahya Saree formally announced an immediate ban on all ships bound for Saudi Arabia, framing it as a 'siege for siege' equation. The Houthi movement then officially declared a maritime blockade, with a report noting that Saudi oil exports via Yanbu had tripled to 1.75 million barrels per day in March 2026. The Zioneer's analysis now builds on that figure, examining the impact on the 4.5 million bpd pipeline capacity.
As The Zioneer reported on July 18, Yanbu port was targeted by an Iranian missile attack, highlighting its strategic vulnerability. The Houthi blockade follows the effective closure of the Strait of Hormuz amid U.S.-Iran tensions, which has forced Saudi Arabia to rely on the Red Sea route for exports. The analysis notes potential alternative routes, including the Suez Canal and a longer voyage around Africa, but cautions that these may be economically unviable for East Asian markets.
It remains unclear how the Houthis intend to enforce the blockade, and whether Saudi Arabia will seek international naval escort operations or other measures to ensure continued exports. The analysis also notes that the pipeline's loading facilities at Yanbu limit throughput, which may constrain the impact of the blockade.
