As conflict between U.S.-Israeli forces and Iran effectively shutters the Strait of Hormuz, Saudi Arabia has activated a 45-year-old contingency plan to bypass the blockaded waterway and keep global crude markets afloat.

The centerpiece of this strategy is the East-West pipeline, a 1,200-kilometer artery that transports crude from the kingdom’s eastern fields to the Red Sea port of Yanbu. 

Long considered a redundant relic of the 1980s Iran-Iraq War, the line is now the primary exit point for Saudi exports.

State-owned oil giant Saudi Aramco has rapidly reoriented its logistical center of gravity toward the west due to the lingering threat of Iran closing the Strait of Hormuz. 

In June 2025, the East-West pipeline emerged as a viable alternative, with Pakistan considering using it for the oil imports if the Strait of Hormuz is closed— a situation currently witnessed amid the ongoing conflict in the Middle East. 

Ship-tracking data shows crude exports from Yanbu reached a five-day average of 3.66 million barrels per day through Friday—nearly half of the nation’s prewar total and a fourfold increase from normal levels.

"The East-West pipeline is looking like a strategic masterstroke right now," said Jim Krane, energy fellow at Rice University. 

"The entire global economy is better off with the line in operation."

The pipeline’s importance cannot be overstated. Roughly 20 million barrels of oil normally transit the Strait of Hormuz daily. Without the Saudi bypass, global supply shocks would likely be far more severe. 

Currently, Brent crude sits at approximately $112.19 a barrel, up 55% since the conflict began three weeks ago.

However, the route is not without peril. On Thursday, an Iranian strike on the Samref refinery in Yanbu briefly halted loadings, underscoring the vulnerability of the infrastructure. 

Additionally, tankers departing Yanbu must navigate the Bab el-Mandeb Strait, where Houthi militants hold a potential "veto" over Red Sea traffic.

Aramco CEO Amin Nasser recently called the situation the "biggest crisis" the regional industry has ever faced. 

Despite the tension, Aramco has signaled it can permanently expand the line’s capacity to 7 million barrels per day.

For now, a flotilla of at least 25 supertankers remains stationed at Yanbu. 

While other regional producers like the UAE and Iraq struggle with their own bypass routes, the world remains tethered to the Saudi "lifeline" to prevent a total energy collapse.
