Four routes carried Gulf crude to the world. As of September 14, one is operational.
In Post #75, I mapped Houthi territorial control of Bab el-Mandeb and noted that Yanbu’s northbound flow—crude piped across Saudi Arabia to the Red Sea, then through SUMED to Europe—remained at 2.5 mb/d. That was wrong. Hours after I published, Saudi Arabia shut down the East-West Pipeline. Yanbu’s northbound flow isn’t 2.5 mb/d. It’s zero.
The Four Routes
Before February 28, Gulf crude reached the world through four export pathways. Each one is now compromised by a different actor, through a different mechanism, on a different timeline. The convergence is not coordinated. It’s worse than that—it’s structural.
Day 198. IRGC restricted zone. ~6–13 transits/day vs 85 pre-war. 418 vessels holding. Chinese and allied traffic passes; everyone else needs escort or goes dark. ~1–2 mb/d reaching market.
Day 4. Iraqi drone strikes hit pump stations Sep 10–11. Fire damage at Al Mesba’ah and Al Dhekra. Saudi Energy Ministry: “precautionary shutdown.” Satellite: 100km smoke plume. 0 mb/d. Pipeline was carrying 5 mb/d.
Houthis seized Perim Island Sep 11. Mokha, Dhubab, Zuqar, entire Red Sea coastline under Houthi control. Saudi vessels embargoed. Even if pipeline restarts, southbound traffic faces shore-based denial. Effectively 0 mb/d to Asia.
Abu Dhabi fields → Habshan → 380km → Fujairah → Gulf of Oman. No attacks since May. Running near capacity. Only carries Murban crude—offshore Abu Dhabi grades still need Hormuz. 1.5 mb/d sustained.
Pre-crisis Gulf exports: ~20 mb/d
Current accessible flow: ~2.5–3.5 mb/d
Of which 1.5 mb/d is a single pipeline carrying a single crude grade to a single port.
What Failed Simultaneously
The four compromised routes share no common actor. Hormuz is an Iranian military operation. The East-West Pipeline was struck by Iran-backed Iraqi militias—Iraq’s PM dismissed a military commander from Maysan Governorate after confirming the launch origin. Bab el-Mandeb is a Houthi ground campaign. And the diplomatic track—Oman’s Salalah meeting, which briefly gave markets a reason to sell—collapsed when Bahrain refused to attend, calling the process “appeasement.”
Four routes. Four actors. Four mechanisms. One pipeline left.
Brent fell ~$3 on Friday when Salalah was announced. That’s the fifth iteration of the repricing cycle mapped in Post #70: diplomatic signal → market discounts supply risk → signal fails → reversion. The signal failed before the meeting could convene. Iran’s FM Araghchi stated that the Oman agreement “by no means signifies the reopening of the Strait of Hormuz.” The market priced reopening. There is no reopening.
ADCOP: Anatomy of the Last Route
The Abu Dhabi Crude Oil Pipeline runs 380 km from Habshan to Fujairah. Built 2012. Capacity: 1.8 mb/d surge, 1.5 mb/d sustained. Twelve million barrels of storage at Fujairah, three single-point mooring buoys for deepwater loading, one main pumping station, one intermediate. It carries only Murban crude—Abu Dhabi’s onshore grade. Offshore Abu Dhabi production (Upper Zakum, Umm Shaif, Das Island) still loads through Hormuz.
In Post #67, I mapped five vulnerabilities: fixed target, single port, Gulf of Oman not guaranteed safe, weather, capacity ceiling. All five remain. What’s changed is the denominator. In August, ADCOP was one of three active bypass routes. Now it’s the only one.
The West-East 1 expansion—which would double ADCOP’s capacity—is 50% complete, targeting 2027. ADNOC CEO Al Jaber confirmed the accelerated timeline in May. Until then, 1.5 mb/d is the ceiling.
A correction from Post #75: I stated ADCOP capacity at 1.8 mb/d. That’s the temporary surge rating. Sustained capacity is 1.5 mb/d. When the system you’re mapping is this fragile, precision matters.
What Saudi Arabia Cannot Export
ADCOP is not Saudi infrastructure. It belongs to ADNOC, and it carries only UAE crude. Saudi Arabia’s own export capacity—the world’s largest—is effectively landlocked:
- Eastern terminals (Ras Tanura, Juaymah, Dhahran): Require Hormuz. Filtered.
- Yanbu (western terminal): Requires East-West Pipeline. Shut down.
- Jizan refinery: Day 49. Offline since Jul 27 across four Houthi strikes. Zero exports recorded in August.
Saudi Arabia produces ~9.5 mb/d (Aramco Q2). Right now, nearly all of it is going into storage or staying in the ground. Trump refused MBS’s request for US strikes on Houthi positions. No external cavalry. The kingdom’s export routes were designed for a world where at least one of the three—Hormuz, the pipeline, or Bab el-Mandeb—was always open. For the first time since the East-West Pipeline was built in 1981, none of them are.
The Pipeline Variable
The East-West Pipeline has been down for 72+ hours. Saudi Aramco restored a similar strike in April within days. The September attack hit multiple pump stations across a wider area—satellite imagery shows fire damage at both Al Mesba’ah and Al Dhekra, with nine fire locations and a visible oil stain. Polymarket: 37% restart by September 15. 84.5% by September 30.
If it restarts this week, the supply chain map shifts: Saudi crude reaches Yanbu again, and the northbound SUMED route to Europe reopens. But the southbound route—Yanbu through Bab el-Mandeb to Asia—does not. Houthi territorial control of Perim Island and the entire Red Sea coastline is not a pump station that Aramco can repair. And even a rapid restart proves the thesis: the infrastructure that carries a third of global oil exports can be taken offline by a handful of drones launched from southern Iraq.
Monday
Brent closed Friday at $104.61. The market priced two things last week: pipeline shutdown (bullish) and Salalah diplomacy (bearish). The diplomacy is now dead. The pipeline is still down. WTI opened Sunday at $102.52, up 2.5%.
IEA’s September report revised demand destruction to −2.5 mb/d. Inventories have fallen 507 million barrels since February. SPR sits at 285 million barrels—a 1982 low. Demand is collapsing, but supply is collapsing faster.
The question the market will answer Monday is whether 1.5 mb/d of uncompromised Gulf exports—a single pipeline, carrying a single crude grade, to a single port—is priced.
