NextFin News - Saudi Aramco is in talks with Asian refiners to formalize a regular shuttle service that carries crude through the war-risk zone of the Strait of Hormuz for ship-to-ship handoff outside the chokepoint, as the kingdom fights to defend its market share in Asia after attacks on its cross-country pipeline cut off its main Red Sea export route.
The talks mark a strategic pivot for the world's largest oil exporter. For months, Riyadh had been trying to bypass the strait entirely, sending oil across the Arabian Peninsula through the East-West pipeline to the Red Sea port of Yanbu. When drone attacks halted that pipeline on Sept. 10, Saudi Arabia found itself forced back to the waterway it had spent months and billions trying to avoid.
The stakes are concrete. Asia buys the bulk of Saudi crude - China alone accounts for 22 percent of Saudi oil exports, followed by South Korea at 14 percent, Japan at 13 percent, India at 10 percent and the United States at 5 percent. Every week that volumes stay constrained is a week in which buyers in those markets test alternatives from the Americas, West Africa and the North Sea.
The Situation: A Wartime Workaround Becomes a Regular Service
The arrangement under discussion is a ship-to-ship transfer, or STS, operation. Smaller shuttle tankers brave the strait with their transponders switched off to avoid detection, then offload their cargo onto much larger very large crude carriers waiting in the relatively safer waters of the Gulf of Oman, near Fujairah in the United Arab Emirates and Sohar in Oman. The shuttle tankers then turn around quickly for another run, while the big vessels sail on to Asia with the risk portion of the voyage already behind them.
This is not a new idea for the region - it is the same wartime workaround that Abu Dhabi National Oil Co. has been running. What is new is the move from ad hoc spot deals toward a formalized, scheduled service. Saudi Aramco has already sold about 20 million barrels of spot crude to Asian refiners for September and October pickup from locations just outside the strait, according to traders familiar with the matter. The buyers included Chinese state-owned and independent processors and other importers in East Asia. Saudi Aramco declined to comment.
The volumes tell the story of how much capacity the workaround now carries. Ship-to-ship transfers of liquid cargo in the Gulf of Oman averaged 3.7 million barrels a day from the start of the war on Feb. 28 through Sept. 21, up from just 160,000 barrels a day in 2025, according to shipping analytics firm Kpler. The pace accelerated sharply in September, averaging 8.2 million barrels a day from Sept. 1 to Sept. 24.
"Our understanding is that the region is gradually meeting its current operational limits, also evident by the sheer scaling of operations," Panagiotis Krontiras, a tanker freight analyst at Kpler, said.
Why the Pipeline Route Collapsed
The East-West pipeline, also known as the Petroline, runs 1,200 kilometers from the Abqaiq oil complex in Saudi Arabia's Eastern Province to Yanbu on the Red Sea. It was built during the Iran-Iraq War in the 1980s for exactly this scenario - to allow Saudi oil to bypass trouble in the strait. Its stated capacity is 7 million barrels a day, up from 5 million barrels a day after a 2026 conversion of a second line from natural-gas liquids to crude.
The pipeline's importance was underscored by the production collapse that followed its disruption. Saudi crude production fell to 6.24 million barrels a day in August, down 23 percent from July and the lowest monthly average since 1990, according to OPEC data - a fall of roughly 1.9 million barrels a day driven by the Houthi maritime ban and attacks on Red Sea coastal infrastructure.
Saudi Energy Minister Prince Abdulaziz bin Salman said on Tuesday that oil pumped through the East-West pipeline reached 5.8 million barrels a day. The kingdom had aimed to restore about half of the pipeline's capacity within days of the Sept. 10 halt, with full capacity possible in about six weeks, according to people familiar with the matter.
The Yanbu terminal at the western end of the line has an export capability of 3 million barrels a day, though it usually handles 1 million to 1.5 million barrels a day. Even at full pipeline capacity, a large share of Saudi exports still needs to flow through the Gulf - the strait normally carries about 20 million barrels a day of crude oil and products.
The Cost of the Shuttle: Insurance and Freight
The shuttle model works, but it is expensive. War-risk insurance for a strait transit is running at 40 times the peacetime rate, according to market trackers. Trade press has quoted single VLCC voyages at up to $10 million, against roughly $250,000 in peacetime. A modern VLCC is valued at $100 million to $150 million; at a normal premium of 0.15 percent, war-risk coverage costs roughly $150,000 to $225,000 per voyage. At crisis premiums of 5 percent, that jumps to $5 million to $7.5 million per transit.
Six insurance clubs and quotas have pulled out of covering the zone, which Lloyd's Joint War Committee has listed as a high-risk area covering the Arabian Gulf. At that level, spot transit is priced beyond the reach of most operators even while the strait remains physically passable.
The economics explain why Aramco, rather than the buyers, is absorbing the strait portion of the journey. Under the deals being struck, buyers pick up the crude outside the strait - they are not responsible for the high-risk transit. That shifts the insurance and security burden onto the seller, but it keeps the cargo moving and, more importantly, keeps the customer from walking.
There is also a hidden cost that does not show up on an insurance invoice: the shuttle model consumes tanker capacity. A VLCC that spends days doing short back-and-forth shuttle runs is not available for long-haul voyages, tightening the global fleet exactly when longer detours around Africa are also soaking up ships. That is why freight rates have become a second oil shock inside the first one.
The Market Reaction
Oil prices have been whipsawed by the competing forces of disruption and workaround. On Oct. 7, Brent crude futures rose 93 cents, or 0.92 percent, to $101.51 a barrel, while U.S. West Texas Intermediate rose 82 cents, or 0.92 percent, to $90.25, as the market weighed Houthi attacks on Saudi Arabia against increased supplies of Middle East crude. A day earlier, Brent had fallen to $97.72 a barrel, down 2.60 percent, as Middle East exports recovered.
The message from the market is clear: traders are watching whether the workarounds can keep barrels flowing, not whether the strait is theoretically closed. Crude exports from the Middle East exceeded pre-war levels on four days during the last week of September, shipping data showed, underscoring the resilience of regional oil flows despite attacks on ships passing through the strait.
But resilience has a price, and it is being paid in margins. The shuttle model consumes tanker capacity, and war-risk premiums have become a de facto tax on every barrel that moves through the Gulf. The market is not pricing a full closure - it is pricing a permanently more expensive normal.
The Bigger Fight: Market Share in Asia
The formalization push is about more than moving barrels. It is about keeping customers. Saudi crude and petroleum products sales generated 606.5 billion riyals, or $162 billion, for state coffers in 2025, accounting for more than half of government revenues.
Sustained disruption would cut deep into public finances. UBS Research now forecasts the 2026 budget deficit reaching 5 percent of gross domestic product against an original target of 3.3 percent.
The competitive threat is structural, not temporary. Production in the Americas is expected to exceed 32 million barrels a day by 2030, according to analysis cited in market reporting. That puts pressure on Gulf producers to secure reliable export routes and protect their market share in Asia as alternative supplies grow.
"The missing barrels are also higher sulphur crude. Saudi grades such as Arab Light and Arab Medium are difficult to replace, like-for-like, because the alternatives available from the U.S., Kazakhstan and much of the North Sea are generally lower in sulphur content. That puts particular pressure on refiners configured for Middle East crude, many of them in Asia, which takes the largest share of Saudi exports," Rishi Rajanala, a research specialist in oil Americas at LSEG Data & Analytics, said.
That sulphur advantage is Saudi Arabia's moat - but a moat does not matter if the customer cannot physically receive the cargo. Some European refiners with cancelled Saudi cargoes are already sourcing crude from the North Sea and seeking cargoes from the Americas and Central Asia. Once a refiner qualifies an alternative supplier during a crisis, the next time Saudi cargo is late, the alternative is one phone call away.
Cyclical or Structural: What This Really Is
This is the question that determines how to read the story. The disruption itself is cyclical - conflicts de-escalate, pipelines are repaired, insurance markets normalize. The 1980s tanker war in the same strait eventually passed, and traffic returned.
But the response is structural. The shuttle service being formalized is not a temporary fix that will be unwound when peace returns. It is a permanent addition to Saudi Arabia's export toolkit, alongside the pipeline bypass and the Red Sea routes. Once buyers are accustomed to picking up cargo outside the strait, and once the tanker fleet is configured around shuttle operations, the trade pattern does not simply revert.
The same logic applies to the buyers. Every Asian refiner that qualifies an alternative supplier during this crisis - a U.S. Gulf Coast grade, a West African crude, a Brazilian barrel - has opened a door that will not fully close. The relationship is re-established; the next time Saudi cargo is late, the alternative is one phone call away.
So the right read is: a cyclical shock that is triggering a structural rewiring of the oil trade. The shock will fade. The rewiring will not.
The evidence floor for this call: a structural claim needs evidence of a permanent regime change in rules, infrastructure, or industry structure. Here the evidence is the infrastructure itself - STS capacity built out more than fifty-fold, from 160,000 barrels a day in 2025 to more than 8 million barrels a day in September, new pickup points established at Fujairah and Sohar, and buyers reconfigured to accept delivery outside the strait. None of that is undone when a ceasefire is signed.
The Counter-Thesis: The Workarounds Are Working
The strongest case against the alarmist read is simple: the oil is moving. Middle East exports have surpassed pre-war levels. The strait has never been fully closed - it has just gotten expensive. And Iran has an incentive to keep some traffic flowing, because a total closure would destroy the oil revenue it still earns and invite a wider war.
This argument has real force. A chokepoint that is merely pricey does not create the supply shock that a chokepoint that is closed would create. The U.S. military said it had aided the passage of 660 million barrels of oil through Hormuz since May - a substantial flow, even if far below the roughly 20 million barrels a day that moved before the war.
But this counter-thesis misses the point of what Saudi Arabia is doing. Riyadh is not pricing for today's flow; it is pricing for the risk that today's flow stops tomorrow. The shuttle service is insurance against the single event that would actually matter: a day when nothing gets through. And the fiscal math means Riyadh cannot afford to find out whether that day comes. With a budget deficit projected at 5 percent of GDP, every barrel of lost export revenue hits a state budget already under pressure from ambitious domestic spending.
The falsifying signal for the structural-rewiring thesis is specific: if Middle East crude exports through the strait return to pre-crisis routing patterns - meaning buyers resume taking delivery at Gulf terminals and transiting normally, with war-risk premiums back below 5 times peacetime levels - within six months of a durable ceasefire, then the trade pattern has reverted and the structural call is wrong. If, instead, STS pickups outside the strait remain above 3 million barrels a day a year after hostilities end, the rewiring is permanent.
What to Watch
Three signals matter most in the coming months:
- Pipeline restoration: The East-West pipeline reached 5.8 million barrels a day of flows by Oct. 6, according to the Energy Minister. Any official timeline for a return to the full 7 million barrels a day would immediately reduce the pressure on the shuttle route.
- STS throughput: Kpler's data on Gulf of Oman transfers is the real-time gauge of whether the workaround is scaling or hitting its ceiling. The September average of 8.2 million barrels a day is close to what analysts describe as the region's operational limit.
- Insurance pricing: The 40-times-peacetime war-risk rate is the market's verdict on danger. A sustained move below 10 times would signal that the strait is returning to normal commerce.
For investors and traders, the exposure runs through several channels: crude benchmarks such as Brent and WTI, tanker rates where the VLCC market is being tightened by shuttle duty, and the fiscal position of Gulf states whose budgets depend on uninterrupted oil revenue.
The Bottom Line
Saudi Arabia's move to formalize Hormuz shuttles is an admission as much as an adaptation. The world's largest oil exporter has concluded that it cannot wait for the strait to become safe again - it must build a system that works while the strait is dangerous.
The base case is that the shuttle service keeps enough barrels moving to prevent a true supply shock, with Brent range-bound between $95 and $110 as the market balances disruption against demonstrated resilience. The upside case is a fresh attack on pipeline or terminal infrastructure that takes more capacity offline, pushing Brent toward the $120 level that some analysts have flagged. The downside case is a negotiated de-escalation that reopens normal routing faster than expected, sending prices back toward the $80s.
The central judgment: this is not the prelude to a supply shock. It is the market's proof that it has learned to live with the disruption - and that the real story is not the oil that is stuck, but the trade patterns that are being rewritten while everyone watches the price.
Saudi Arabia is not betting that the Strait of Hormuz will reopen. It is betting that it no longer needs to.
