Saudi Arabia is sending more crude back through Hormuz — the exact chokepoint it spent the war routing around. Aramco sold about 20 mn barrels to Asian refiners this week for ship-to-ship pickup in the Gulf of Oman, just outside the strait, with cargoes loading through September and October, traders familiar with the matter told Bloomberg. Buyers included Chinese state-owned and independent refiners, alongside other importers in East Asia.

That's a sharp scale-up on where the outside-Hormuz transfer system stood in August, when Aramco moved at least 4 mn barrels to China through the same ship-to-ship model — a rough comparison, since the two figures cover different windows, but the direction is clear. The shift comes as the Kingdom's main workaround, the East-West Pipeline, stays offline with no confirmed restart date, pushing Aramco back toward the route it built the pipeline to avoid in the first place.

Why it matters: For six months, the East-West Pipeline let Saudi Arabia sidestep the worst of the Hormuz risk that's throttled other Gulf exporters since the Iran war began. With the pipeline down, Aramco isn't choosing between Hormuz and a safer route — it's choosing between Hormuz and idle barrels. Scaling up outside-Hormuz sales this fast signals Riyadh is accepting more strait exposure rather than leaving crude stranded, even with tanker traffic through Hormuz still a fraction of pre-war levels.

Nobody agrees on when the pipeline comes back

The public and private timelines don't match. The pipeline should be flowing again soon, US Energy Secretary Chris Wright told CNBC (watch, runtime: 04:06): “It's still a detailed assessment, but I think it will be measured in days.” Saudi Arabia is also taking steps to move more oil out of Hormuz with US military assistance, he added, Reuters reports. Citigroup is on the same page on timing: a note from analysts including Francesco Martoccia, said operations on the line should resume “soon,” with stockpiles at the Kingdom's west coast export terminals covering exports in the meantime, Asharq Business reports. But sources close to the repair work gave Reuters a wider range — one said the damage could take five to six weeks to fix, another said partial pumping could resume sooner while repairs continue.

Riyadh's own timeline splits the difference. The Kingdom is pushing for a partial restart within days, but full repairs could take six to eight weeks, the Wall Street Journal reports, citing people familiar with the matter — wider than Reuters' five-to-six-week estimate. The pipeline is more likely to stay offline until around early October, Dalga Khatinoglu, an energy analyst, tells EnterpriseAM.

Washington's help has limits: The US has resisted Saudi requests for direct military intervention beyond intelligence support, three sources tell Reuters — a constraint that helps explain the gap between Wright's public optimism and the private estimates.

The buffer only buys time

That cushion is shrinking fast, and now there's a number attached to it. Yanbu's stocks have fallen by more than 7 mn barrels over the past two months to around 9 mn barrels as of Monday, per Kpler data cited by the Journal — leaving the Kingdom only a few days of export cover if the pipeline stays down. Cargo schedules are already showing it: at least one Asian refiner has been told its Saudi cargo will be delayed, while several others were still waiting on revised loading schedules Monday.

“There have been no loadings today from Yanbu although there is oil in storage so that is puzzling. It might be that there is congestion at Ain Sukhna or a problem with tanker availability as VLCCs now have to take a longer route to Asia,” Kate Dourian, board member at the Energy Institute's Middle East branch, tells EnterpriseAM.

Aramco also has crude stored in Egypt, at Ain Sokhna and Sidi Kerir, buying extra time for Mediterranean deliveries — but the repair itself looks slow. Satellite imagery shows extensive work underway at the last pumping station before Yanbu, while two other stations appear to have suffered more limited damage, Dourian says. The old Tapline, once a ready-made bypass, was converted years ago to carry natural gas — and it's unclear whether it could be repurposed for crude fast enough to matter this time, Dourian notes.

Egypt helps — but only with crude that already made it west

The Egypt route only works once Saudi crude has already crossed the peninsula. When Houthi pressure made Bab Al Mandab more dangerous earlier this summer, Aramco could send crude through the East-West Pipeline to Yanbu, ship it north to Ain Sokhna, pump it across Egypt through the 2.5 mn bbl/d Sumed pipeline, and reload at Sidi Kerir on the Mediterranean. Saudi deliveries to Ain Sokhna had averaged around 755k bbl/d this year, with roughly 18.4 mn barrels in storage at Ain Sokhna and 19.5 mn barrels at Sidi Kerir.

With the East-West Pipeline down, that supply chain has nothing new feeding it. Sumed can route around Bab Al Mandab, but it can't route around a broken pipeline — the crude has to reach Yanbu first. Once the barrels already stored at Yanbu and in Egypt are drawn down, there's no obvious way to replenish them from Saudi Arabia's eastern fields.

That's already showing up in Mediterranean flows. Only around 2.1 mn barrels are currently scheduled to move from Sidi Kerir to Poland in September, down from 6.6 mn barrels in August. Polish refiner Orlen, which gets around 40% of its crude from Aramco, is replacing the shortfall with US, Algerian, and Norwegian barrels. Aramco has also already delayed some deliveries to European customers directly from Yanbu, pushing European crude prices higher — a squeeze that predates this week's outside-Hormuz sales.

For Asian buyers, the Egypt route was never the answer anyway. “Saudi barrels can be redirected through Egypt and Sumed pipeline but it creates logistical bottlenecks given VLCCs cannot pass the Suez canal, so must unload via the pipeline and be picked up by another vessel in the Mediterranean. It is also not the principal demand centre of Asia and consequently adds around 25 days sailing time,” energy analyst Sasha Foss tells EnterpriseAM.

The fallback is now the plan

This is the workaround Aramco has been testing since summer — now it's running at scale. The company has already piloted a model in which crude loads at Ras Tanura, crosses the strait aboard shuttle vessels and is transferred ship-to-ship to long-haul tankers waiting outside the Gulf near Fujairah and Sohar.

The scale-up comes despite Hormuz getting riskier, not safer. Commercial vessel traffic through the strait fell to just four transits on Monday, from ten a day earlier and around 125 a day before the war. Dourian had flagged the open question before this week's sales: whether Riyadh would risk scaling shuttle operations back up after Saudi-linked tankers came under attack, or whether more vessels would instead cross without broadcasting their positions.

The constraint has shifted from how much Aramco can produce to how much it can move. “Production capacity is not the important metric in the current conflict, the key issue is the ability to bring oil to market,” Jamie Ingram, managing editor at Middle East Economic Survey (MEES), tells EnterpriseAM. Saudi export infrastructure can handle substantially more crude than it's currently moving, he adds — the routes feeding international markets are what's constrained, which is why additional export options matter well beyond this specific outage.

If the pipeline stays down and Hormuz sales can't fill the gap, the next move is a production cut. Khatinoglu expects Saudi Arabia could be forced to cut output by another 2-2.5 mn bbl/d if it can't increase exports through Hormuz while the pipeline remains offline — a scenario that gets more likely the longer Wright's’ “days” timeline slips.

Asia is where the squeeze lands

Bab Al Mandab may be physically open, but it hasn't returned to normal commercial use. Tanker traffic through the strait remains well below pre-2023 levels, Ingram says — operators are still willing to make the crossing largely because they believe their cargo or trading profile leaves them relatively insulated from Houthi targeting, including tankers carrying Russian oil. The Houthis' territorial advances around the strait have also made it easier for them to threaten shipping and tighten pressure on the route, he adds.

That's part of why Asian refiners are pulling back from the western route rather than the eastern one. Some buyers have grown reluctant to lift Saudi crude from Yanbu or Sidi Kerir because avoiding Bab Al Mandab on the return leg means routing around Africa — adding weeks to the voyage and pushing up freight costs. Chinese refiners haven't loaded Saudi crude from either Yanbu or Sidi Kerir since August, Reuters reports, leaving the eastern Saudi terminals and the outside-Hormuz transfer system as the more workable, if riskier, route for Asian barrels. Asian refiners have also asked Aramco directly for updates on their upcoming Yanbu loadings, Bloomberg reports.

The bottom line

The immediate disruption is to barrels and shipping; the fiscal squeeze, if it comes, will take longer to reach Riyadh's flagship investment plans. Saudi Arabia and its Gulf peers have roughly USD 3 tn in oil-revenue reserves and sovereign funds that could cushion weaker budget revenues for some time, Khatinoglu argues. Some discretionary spending has already been curtailed, Ingram notes, but Riyadh has so far shown a willingness to run sizeable budget deficits rather than pull back from projects tied to economic growth and diversification. A prolonged export squeeze would likely show up first in higher borrowing and cuts to lower-priority spending, well before it forces a broader retreat from the kingdom's core diversification agenda.
