10 October 2026 | OilWatch analysis
Saudi Arabia has its Hormuz bypass running again, and Middle East crude exports are back at pre-war volume on Kpler's estimates. What has not come back is resilience. The barrels now reach market on more legs, and more of those legs are within range of someone who wants to break them.
This week showed the exposure. Saudi Arabia's civil aviation authority said attacks on Abha airport on Tuesday 6 October and Riyadh's King Khalid International on Wednesday 7 October killed three foreign residents and injured 36; the Houthis claimed both (Al Jazeera, 7 Oct). Two further attacks on the Riyadh airport on Thursday 8 October killed three Saudi nationals and injured several others, the authority said on 9 October; Saudia said one of the dead was its employee (Reuters via Investing.com, 9 Oct; Reuters via MarketScreener, 9 Oct). These are separate counts: six people killed across the three days.
The authority said the second attack on 8 October struck a Saudia aircraft. How the damage was caused, whether by a direct hit or by debris from an interception, has not been officially established; three people briefed on the matter told Reuters on 8 October that shrapnel from an interception or another projectile was responsible (Reuters via Al-Monitor, 8 Oct). The Houthis have also warned workers at Saudi energy plants that the plants would be targeted.
None of this is evidence that the East–West Pipeline or Yanbu was hit this week. It is evidence that the group threatening the Red Sea exit is escalating against the kingdom itself.
The summer showed how fragile the sea leg is
The case that sea-lane risk constrains the bypass does not rest on theory alone. Something close to it was observed this summer, though the measurements are less clean than they first look.
The Houthis declared a maritime embargo on Saudi Arabia on 20 July. Visible loadings at Yanbu then fell, but how far depends on who is counting. For the week beginning 3 August, Vortexa put Yanbu loadings at 2.38 mb/d, Kpler at 1.78 mb/d and AXSMarine at 0.85 mb/d. Analysts said every Yanbu cargo since 23 July had involved vessels without continuous AIS coverage, so part of the apparent fall may be ships that loaded unseen (Reuters via OilMonster, 13 Aug).
For August as a whole, Vortexa estimated Yanbu loadings at 3.2 mb/d and Kpler at 1.5 mb/d, the lowest since the war began on either measure. Reuters attributed the decline to intensifying Houthi attacks near Bab el-Mandeb (Reuters via gCaptain, 10 Sep). Some cargoes went north instead: loadings at Sidi Kerir, the Mediterranean end of Egypt's SUMED pipeline, hit a record 2.17 mb/d in early August, about 90% of it Saudi crude, according to Vortexa.
What this establishes is limited but important. These are terminal loadings and tracked cargoes, not metered pipeline throughput, and the providers' monthly estimates differ by 1.7 mb/d. They do show that a threat to the sea route coincided with a sharp drop in visible Red Sea loadings and a shift north, weeks before drones from Iraq forced the pipeline shut.
What 5.8 million barrels a day does and does not tell us
On 6 October Energy Minister Prince Abdulaziz bin Salman told a forum in Bahrain that East–West Pipeline flows were back to 5.8 mb/d as of that morning. Argus reported it as a flow in barrels per day; Reuters reported the oil pumped had reached 5.8 million barrels; Al Jazeera and Saudi Gazette framed it as capacity restored (Argus, 6 Oct, also reproduced by World Ports; Reuters via Khaleej Times, 6 Oct; Al Jazeera, 6 Oct; Saudi Gazette, 6 Oct). It was the first throughput figure from Riyadh or Aramco since drones launched from Iraq forced the line shut on 10–11 September. Aramco restarted it on 22 September at reduced rates (OilPrice, 6 Oct).
Three different things are easy to conflate:
| Measure | What it means | Public evidence, 10 Oct |
|---|---|---|
| Reported throughput | 5.8 mb/d on the morning of 6 Oct | Ministerial statement; no published series |
| Restored operating capacity | What the repaired line can carry | Not independently reported |
| Demonstrated sustainable throughput | Flow held over weeks and corroborated | Not yet shown |
Private estimates in the days before the statement varied widely. Industry sources put flows near 2 mb/d and Kpler at 2.65 mb/d at the end of September; a source told Bloomberg that Aramco was pumping close to 6 mb/d by 2 October; Argus sources had put flows at 5.5 mb/d a week before 6 October (Bloomberg, 2 Oct, summarised by Egypt Oil & Gas). Argus sources also say three of the line's 11 pumping stations were damaged in September, one significantly, while the pipe itself was not. Whether 5.8 mb/d is sustainable on that station set is a separate OilWatch engineering question; this article does not settle it.
Pipeline barrels are not export barrels. The line also feeds west-coast refineries, power stations and desalination plants. Two figures are often set side by side, but they are drawn on different boundaries:
- Pipeline side. Bloomberg's source said that of close to 6 mb/d pumped, about 4.5 mb/d was available for export after supplying west-coast refineries. That figure is net of refinery feed.
- Terminal side. Kpler estimated in late July that Yanbu can sustainably load about 4.5–4.7 mb/d of crude, including domestic deliveries; in June about 0.6 mb/d of Yanbu's 4.76 mb/d of movements stayed inside Saudi Arabia (Kpler, 28 Jul). That figure is gross of domestic shipments.
Because one is net of domestic use and the other gross of it, and current domestic shipments from Yanbu are not public, the two cannot be compared directly. We therefore draw no conclusion here about whether the pipeline, the terminal or the sea route is the binding constraint today. The narrower point holds: any pipeline figure overstates delivered exports by whatever is used at home, and terminal and shipping limits apply on top. Domestic demand is itself moving; Argus reports Aramco shut its 400,000 b/d Jizan refinery after a Houthi attack in early September.
Bab el-Mandeb: contested coast, unproven sea lane
Before the July embargo, most Yanbu crude exports left the Red Sea southward through Bab el-Mandeb: in June, Kpler counted about 3.3 mb/d of 4.1 mb/d heading to Asia that way (Kpler, 28 Jul). Since then more has gone north, and the current split is not published. Not every Saudi barrel depends on the strait, but the Asia trade still largely does.
Control of the shore has changed hands. Houthi forces took Mocha on 10 September and pushed to the Hanish islands (Reuters via gCaptain, 10 Sep). On 5 October Saudi-backed government forces said they had retaken the coast around the strait up to Mocha. Reuters could not verify the extent of the gains, the Houthis called the claims baseless, and Reuters noted the group could still strike ships with drones from other positions (Reuters via bdnews24, 6 Oct). On 9 October Saudi Arabia's ambassador to Yemen said in a social media post that Bab el-Mandeb had been cleared of Houthis. Reuters could not verify that claim, and reported that Houthi forces remained in Mocha, a little way up the coast, while government forces fought for nearby hills overlooking the area (Reuters via MarketScreener, 9 Oct).
Even confirmed control of the coast would not make the lane safe. Missiles and drones outrange a front line, and shipowners and insurers decide whether a corridor is usable. That shows up in loadings, transit counts and war-risk premiums, not in communiqués. Kpler counted about 32 vessels a day through Bab el-Mandeb in early August, against about 50 before the embargo (Reuters via OilMonster, 13 Aug).
The Houthis' record against Saudi oil assets is not clean. Argus reports Aramco shut Jizan after a Houthi attack in early September. The group has since claimed strikes on Aramco facilities at Yanbu on 24 September and Rabigh on 5 October; Saudi Arabia has not confirmed either, and on 24 September an air-defence unit intercepted a missile and a drone in the wider Yanbu region (Al Jazeera, 24 Sep; Reuters via bdnews24, 6 Oct). Saudi officials disputed an earlier claim on an Aramco facility in Riyadh (OilPrice, 6 Oct). Claims are not hits. But the prior on a hit is not zero.
There is a northern exit. Crude can cross Egypt through the 2.5 mb/d SUMED pipeline or transit Suez, where a single tanker can carry at most about 1 million barrels. Kpler judged the northern route physically credible but unproven at full scale, and identified the return of empty tankers southbound through Suez as its tightest constraint (Kpler, 28 Jul). Oil is not stranded when Bab el-Mandeb closes. It gets slower and dearer.
Volume is back. The routing is what changed.
The headline numbers look like recovery for crude. Kpler's 6 October note put exports from the Gulf of Oman coast and the Red Sea at 6.7 mb/d, more than double pre-war, keeping total Middle East crude exports at pre-war levels (Reuters via Oman Observer, 8 Oct). Standard Chartered estimates Saudi crude exports rebounded to about 6.9 mb/d in September from 2.45 mb/d in August (OilPrice, 6 Oct). These are crude figures. They say nothing about whether refined-product supply has recovered.
The composition is the story. Standard Chartered puts Gulf crude and condensate exports outside Iran at about 16.5 mb/d in September, near pre-war, but only about 60% crossed Hormuz against 83% before the war. The rest moved through bypass pipelines, alternative ports and ship-to-ship transfers.
Hormuz itself is not normalising. Kpler counted seven commodity-vessel transits on 6 October, the fewest since 23 July, and estimated crude crossing at no less than 10.1 mb/d, 74% of pre-war. Those counts exclude ships sailing with AIS off. Most of the week's fall was in ship-to-ship transfers in the Gulf of Oman, and maritime security sources said attacks on Hormuz tankers in the preceding week were the highest of the war. UKMTO reported a tanker struck by an unknown projectile during a Hormuz transit on 2 October, and projectiles striking a tanker north of Qatar, with casualties, on 7 October. It attributed neither (Shafaq News, 2 Oct, citing UKMTO warning 148-26; Reuters via Oman Observer, 8 Oct).
So the same crude volume now rests on more nodes, several of them newly loaded and newly targeted. That is the difference between availability and deliverability.
Trump's pause covers one actor
President Trump said on 8 October that the US would not attack Iran before the 3 November midterms and called talks with Tehran productive (Reuters via Al-Monitor, 8 Oct). The statement followed reports that US military planners had been preparing options for renewed strikes; CNN reported he had not ruled them out until that post, and that he said the blockade of Iranian ports would remain in full force (CNN via KRDO, 8 Oct).
The pledge is a statement about US strikes on Iran before a date. It is not a ceasefire, it does not end contingency planning, and it does not bind Iran, the Houthis or Iraqi militias. None of the attacks described above were American.
Six checks that will settle it
OilWatch will separate changes in threat from changes in delivered supply using six tests. Not all of them can be run from public reporting, and the table says which.
| Check | Measure | Data access | OilWatch watch-level |
|---|---|---|---|
| Pipeline throughput | Weekly average flow, not a single reading | Public: ministry and Aramco statements, wire and Argus reporting. A series needs commercial data | Sustained below 5 mb/d, or a new shutdown |
| Yanbu loadings | Crude loaded, 7-day average, on more than one provider | Commercial: Kpler, Vortexa, LSEG, Signal Ocean. Public only as press summaries | Below 4 mb/d for two weeks on two or more providers |
| Southern exit | Laden Yanbu tankers passing Bab el-Mandeb | Commercial AIS plus satellite; weakened by dark voyages | Southbound share falling while loadings hold |
| Northern substitution | Saudi crude via SUMED (Sidi Kerir) and Suez | Commercial tracking; partial public data from press and the Suez Canal Authority | A sustained rise, confirming rerouting and its cost |
| Cost of passage | Red Sea war-risk premium; Yanbu–Asia freight | Commercial: brokers and insurers; occasional press | Premium rising faster than Hormuz equivalents |
| Verified damage | Confirmed hits on terminals, pump stations, laden ships | Public: UKMTO, JMIC, Saudi and Aramco statements, wire reporting | Any confirmed hit on Yanbu, Rabigh or the pipeline |
Two rules apply to all six. A cargo loaded with AIS off is unobserved, not absent: we report provider ranges rather than a single figure, and do not count dark voyages as lost exports. The watch-levels are OilWatch editorial choices for when to look harder. They are not historical thresholds and have not been externally validated.
On current evidence, Saudi Arabia has neither lost its export system nor regained its old resilience. It has restored crude volume by leaning on Yanbu and the Red Sea, the route whose visible loadings fell sharply after the July embargo. The bypass is working. Its weakest link is now the water beyond it.
