For decades, Saudi Arabia’s oil advantage was usually measured underground. Enormous reserves, low production costs and the ability to raise output quickly. The turmoil of 2026 is adding another metric. For an exporter exposed to geopolitical chokepoints, what increasingly matters is not only the cost of producing a barrel, but the cost and reliability of delivering it.
That distinction has become unusually visible this month. Saudi Arabia resumed tanker loadings at the Red Sea port of Yanbu after restarting the East-West Pipeline, which had been shut following drone attacks on September 11. Reuters reported on September 29 that pipeline flows had recovered to roughly 2-2.65 million barrels per day, with Kpler expecting 3-4 million bpd in the following days. Restoring the pre-attack rate of about 5.5 million bpd could take another month.
Geography as an asset and a vulnerability
Saudi Arabia possesses something most Gulf producers lack. Large-scale access to two seas. Its East-West Pipeline carries crude from the producing regions in the east to Yanbu on the Red Sea, allowing exports to bypass the Strait of Hormuz.
The infrastructure is substantial. Aramco says the roughly 1,200-kilometre system can handle about 7 million bpd, while the U.S. Energy Information Administration describes it as Saudi Arabia’s principal alternative to the maritime chokepoints around the Arabian Peninsula. Earlier this year, Aramco highlighted the pipeline, west-coast terminals and storage capacity as central elements of its supply resilience.
During the disruption of Gulf shipping, this flexibility became strategically valuable. Reuters estimated that Saudi Arabia diverted around 4 million bpd through the pipeline toward the Red Sea when flows through Hormuz were constrained.
But September demonstrated the limitation of geographical diversification. Risk can be shifted without being eliminated. An exporter that avoids Hormuz becomes more dependent on pumping stations, Yanbu, Red Sea shipping lanes and ultimately the security environment around Bab el-Mandeb.
The new cost of a barrel
This is where the economics of oil security are changing.
According to Reuters, quoted war-risk insurance premiums for Saudi-linked tankers calling at Yanbu rose from below 1% of vessel value in early July to around 3% in September. For Saudi ports farther south, premiums could reach 7%, while chartering a tanker was estimated at more than $500,000 a day. A war-risk premium alone could add roughly $3 million to a voyage from Yanbu and considerably more on some higher-risk routes.
These are not production costs in the conventional sense, but economically they perform a similar function. They determine how much value remains in a barrel once it reaches the buyer.
The old model of energy security focused heavily on spare production capacity. The emerging model requires spare logistical capacity as well alternative pipelines, terminals, storage, tanker access, insurance arrangements and multiple export directions.
The key question is whether such redundancy should now be treated as permanent strategic infrastructure rather than emergency backup. Building excess capacity appears expensive in peaceful periods. In a crisis, however, the ability to switch coasts can be worth more than marginal reductions in extraction costs.
The Russian parallel
Russia provides an imperfect but useful comparison. Its challenge has been driven primarily by sanctions rather than by the physical geography confronting Saudi Arabia, but the result has been similar. Logistics became part of the oil price equation.
After European demand collapsed following 2022, Russian producers redirected much of their seaborne crude toward China, India and Turkey and increasingly relied on a tanker network operating outside traditional Western shipping and insurance systems. For several years, this adaptation helped preserve export volumes despite sanctions.
The lesson for Saudi Arabia is not that it should reproduce Russia’s system. Rather, it is that control over production alone is no longer enough. Tankers, financing, insurance, storage and the political reliability of maritime corridors can become strategic assets comparable to pipelines and oilfields.
From spare capacity to spare routes
Yanbu’s reopening reduces immediate pressure, but it does not restore the old assumption that Saudi oil can always reach markets cheaply through one secure alternative route. The Gulf and the Red Sea now carry different combinations of military, infrastructure and insurance risk.
Saudi Arabia therefore enters a new phase of energy strategy. Its traditional advantage – spare barrels – increasingly needs to be accompanied by spare routes.
The broader implication extends beyond the Kingdom. In a more fragmented geopolitical system, the competitive position of an oil exporter may increasingly depend on a new calculation not simply how cheaply can the barrel be produced, but how many politically and commercially viable ways exist to deliver it?
