Saudi Aramco is strategically rerouting its crude oil exports to bypass the vital, yet now perilous, Strait of Hormuz.
The immediate catalyst for this decision is the effective shutdown of the Strait of Hormuz, a chokepoint for nearly a fifth of the world's oil supply. Escalating conflict with Iran, including direct threats and attacks on vessels, has brought tanker traffic to a standstill. This has forced Saudi Arabia to find an alternative route to get its oil to global markets.
The causal chain is quite clear. First, the geopolitical flare-up made the strait physically unsafe for passage. Second, maritime insurers reacted swiftly by cancelling war-risk coverage or hiking premiums to prohibitive levels, making the route economically unviable. Third, faced with this double blockade, Aramco activated its long-standing contingency plan: the East-West Pipeline, also known as Petroline, which transports crude overland to the Red Sea port of Yanbu.
However, this pipeline is only a partial solution. The Strait of Hormuz normally sees about 15 million barrels per day (mb/d) of crude pass through. The Petroline, even at its maximum estimated capacity of 5-7 mb/d, combined with a similar pipeline in the UAE, still leaves a global supply shortfall of 6 to 8 mb/d. This rerouting, therefore, cushions the blow but cannot fully compensate for a closed Hormuz.
This pivot to Yanbu is not a sudden improvisation but the result of years of strategic planning. Past events, such as the 2019 drone attacks on the Abqaiq and Khurais facilities and persistent threats in the Red Sea from Houthi militants, have highlighted the vulnerability of relying on a single chokepoint. These incidents spurred Saudi investment in building redundancy into its export infrastructure, which is precisely what we see being utilized today.
In essence, while Aramco's decisive action keeps a significant portion of its oil flowing, it doesn't eliminate the market's risk. The world will continue to feel the impact of a constrained Hormuz through higher oil prices, elevated shipping costs, and a persistent 'risk premium'. Moreover, the new route simply shifts the risk from the Strait of Hormuz to the Red Sea's Bab el-Mandeb strait, another vulnerable chokepoint.
