Riyadh Weighs a Bigger Pipeline to a Port the Houthis Now Threaten

Correction, November 1, 2026: The search description still said Saudi Arabia plans the pipeline expansion with Kuwait, Bahrain and Qatar and that Yanbu cannot load what the pipeline carries. As the October 12 correction says, the talks are preliminary, no expansion has been agreed and the Yanbu loading limit had no source; the description and a FAQ heading now match the article.

Correction, October 12, 2026: An earlier version of this article said the East-West Pipeline had been expanded and that Saudi Arabia was negotiating the expansion with Kuwait, Bahrain and Qatar. Reuters, not Arab News, reported on July 7 that Saudi Arabia was in preliminary talks with unnamed neighbours, and no expansion has been agreed. The earlier version also gave a Yanbu loading ceiling of about 4.5 million barrels per day that has no source, misattributed the Kuwait Petroleum Corporation chief executive’s remarks to a Bloomberg interview, and used a Houthi statement and an Abdulmalek al-Houthi quote that could not be verified. It misdated the Houthi attack on Abha to July 20 and gave an unsourced count of six missiles, wrongly said the coalition had not carried out an airstrike in Yemen for four years, dated the pipeline’s conversion to 7 million barrels per day to 2019 rather than 2026, and included unsourced figures for interceptor stocks, construction times, Aramco’s cash flow, Bab al-Mandeb oil flows and the kingdom’s deficit record. These have been corrected or removed.

DHAHRAN — Saudi Arabia is in preliminary talks with neighbouring states on adding up to 2 million barrels per day to the East-West Pipeline at the same moment the Houthis have declared a maritime blockade on Saudi vessels, whose Red Sea exports leave from Yanbu — the only port the expanded pipeline can reach. The expansion would raise the Petroline’s capacity from 7 million to 9 million barrels per day. Bloomberg reported in March that Yanbu’s crude exports had reached about 5 million barrels per day.

Kuwait Petroleum Corporation CEO Sheikh Nawaf Al-Sabah told the Atlantic Council Global Energy Forum in June that Kuwait was “in discussions with our brothers in Saudi Arabia and in the emirates” about pipeline capacity, according to Reuters. Aramco declined to comment. The sequencing is instructive: the expansion was conceived as a Hormuz bypass. The July 20 blockade declaration has turned the bypass route into a contested corridor.

What Is the East-West Pipeline Expansion?

The East-West Pipeline, known commercially as the Petroline, is a 1,200-kilometre twin pipeline system running from Abqaiq in Saudi Arabia’s Eastern Province to Yanbu on the Red Sea. It entered service in 1981, built amid fears that the Iran-Iraq war would cut off shipping through the Strait of Hormuz.

Capacity was later raised to 7 million bpd, a level the line reached in March 2026. That expansion required no new steel in the ground. Aramco converted a second pipe, originally built to carry natural gas liquids, to crude oil service. The infrastructure already existed in the same corridor.

The current proposal is structurally different. According to Reuters, citing five sources close to the matter, Saudi Arabia is in preliminary talks with some neighbours to add up to 2 million bpd of capacity, raising the system’s ceiling from 7 million to 9 million bpd. Reuters said it was unclear whether that would mean upgrading existing infrastructure or building a new pipeline.

Aramco CEO Amin Nasser confirmed in March 2026 that the existing pipeline was operating at full capacity, with approximately 5 million bpd earmarked for export through Yanbu and roughly 2 million bpd feeding west coast refineries. One source told Reuters the expansion would take years, cost billions of dollars and require changes to Saudi crude’s pricing mechanism. No specific budget, engineering contract, or target date has been disclosed.

Can Yanbu Handle the Barrels the Pipeline Already Carries?

Bloomberg reported in March that Yanbu’s crude exports had reached about 5 million barrels per day. Neither Aramco nor the Reuters report on the expansion talks addressed whether Yanbu’s terminals could load an additional 2 million bpd.

Any limit at the port would not be set by the diameter of steel between Abqaiq and Yanbu. It would be set by the number of tanker berths, the tidal depth at approach channels, and the rate at which very large crude carriers can be loaded, turned, and cleared for departure. None of these variables change by adding pipeline capacity inland.

If Riyadh simultaneously plans to expand Yanbu’s terminal infrastructure — new berths, dredged approaches, additional tank farms — the pipeline capacity increase would be a prerequisite, not a solution. But no port expansion was mentioned in the Reuters report. Aramco declined to comment on the pipeline talks. The Saudi and Bahraini government communications offices did not immediately respond to Reuters.

Who Proposed the Expansion — and When?

The talks predate the Houthi blockade. Sheikh Nawaf Al-Sabah, CEO of Kuwait Petroleum Corporation, told the Atlantic Council Global Energy Forum in June that Kuwait was “in discussions with our brothers in Saudi Arabia and in the emirates,” according to Reuters. The Reuters report, citing five unnamed sources, ran on July 7 — thirteen days before Yahya Saree’s July 20 embargo declaration.

When these conversations began, Yanbu was an uncontested export route. The Strait of Hormuz was the problem: the war that began in February had halted shipping through the strait, and Gulf producers had shut in as much as 12 million bpd, according to Reuters. The pipeline was the answer to Hormuz, and expanding it was a way to give the corridor Saudi Arabia had built to outlast Hormuz the capacity to replace the strait entirely.

The Houthi blockade changed the arithmetic overnight. Yanbu exports bound for Asian buyers must transit south through the Bab al-Mandeb strait. The formal embargo, announced by Saree on July 20, put Yanbu’s southbound crude exports at direct risk.

“We affirm the right of our great people to respond to the blockade with a blockade.”

The Houthis cited what they called Saudi Arabia’s “unjust and oppressive siege” of Yemen for nearly 12 years. The expansion talks were designed for a world in which Yanbu was the safe route. That world ended when the Houthis declared the maritime blockade that placed Yanbu under the same category of contested corridor that the pipeline was built to avoid at Hormuz.

Why Would Kuwait, Bahrain, and Qatar Want In?

Kuwait, Bahrain, and Qatar share one structural vulnerability: all three depend heavily on the Strait of Hormuz for crude and LNG exports, according to Reuters. Their tankers must transit the strait, where Iranian naval capabilities and the collapse in commercial traffic have created conditions that leave tanker fleets exposed to interdiction, insurance withdrawal, or outright closure. A connection to the East-West Pipeline would give each state, in theory, access to the Red Sea corridor — routing their crude west through Saudi territory to Yanbu.

Iraq’s Kirkuk-Ceyhan pipeline to Turkey provides another overland bypass. It runs below capacity because of disputes and repeated shutdowns, according to Reuters. The pipeline that exists is underused. The pipeline that is proposed does not yet exist. For Kuwait, Bahrain, and Qatar, the Saudi route is the obvious option.

Indian National Security Adviser Ajit Doval arrived in Riyadh on July 20 to discuss maritime corridors and energy security — the same day as the blockade declaration. The pipeline talks and the Doval visit address the same underlying problem: the survival of Gulf energy exports when both sea lanes are compromised.

Qatar’s involvement carries a specific political charge. Doha is one of the mediators between the United States and Iran. The same government that is mediating a potential ceasefire with Iran is, according to three sources cited by Reuters, considering an export alternative via Saudi territory — an arrangement that would structurally align Qatar’s energy infrastructure with Riyadh’s.

This is not a contradiction so much as a description of what small-state survival requires when both maritime corridors are under threat. Qatar cannot mediate its way out of Hormuz dependence. If Hormuz traffic stays depressed, Doha needs a physical alternative regardless of whether its diplomacy succeeds. The pipeline talks represent a parallel track — economic security running beneath the public diplomatic layer, involving the same capitals, serving the same governments that appear on opposite sides of the mediation table.

Bahrain faces an additional layer of exposure. It has no bypass route, and its Sitra refinery was struck by Iranian missiles several times, according to Reuters. Bahrain’s government did not immediately respond to Reuters’ requests for comment on the pipeline talks.

The Houthi Threat to Yanbu

The Petroline was built to route crude away from the Strait of Hormuz and the Iranian missile threat to eastern Saudi terminals. Yanbu was supposed to provide distance. Against an adversary in Yemen, the margin is real but not decisive.

Saree warned of “comprehensive and decisive escalation” against “any foolish act committed by the reckless Saudi enemy.” The threat envelope could extend to oil infrastructure — not only Yanbu’s port but the pipeline’s western segments that run through open terrain before reaching the terminal.

The Saudi defence posture offers limited reassurance. When the Houthis fired missiles and drones at Abha on July 13, the coalition said air defences dealt with them. After that attack, Saudi authorities closed four southern airports by NOTAM. Air defence allocation between eastern terminals, western terminals, and population centres is not publicly disclosed.

The pipeline’s eastern origin point compounds the vulnerability. The Petroline begins at Abqaiq — the same processing facility that was struck by drones and cruise missiles on September 14, 2019, temporarily shutting down 5.7 million bpd. A strike on the facility could disrupt the pipeline regardless of its expanded capacity, cutting off both the 5 million bpd export flow and the 2 million bpd feeding western refineries. The bypass route depends on the same node that demonstrated its vulnerability seven years ago.

How Long Would It Take to Build?

The Saudi expansion proposal remains at the preliminary-talks stage, and no budget, contract or timetable has been reported. One source told Reuters it would take years to complete.

The Houthi blockade is operational now. Hormuz has been disrupted since late February. The expansion addresses none of these timelines. It is an infrastructure investment premised on the persistence of chokepoint risk beyond the current crisis — a bet that the conditions of 2026 will still obtain years from now.

The earlier conversion misleads anyone who treats it as a template. That expansion — from 5 million to 7 million bpd — was quicker because Aramco converted an existing NGL line that already ran through the same corridor. The steel was already in the ground. Reuters said it was unclear whether an additional 2 million bpd would mean upgrading existing infrastructure or building a new pipeline. If it means new pipe, it is construction, not a conversion.

One source told Reuters that the expansion would require changes to Saudi crude’s pricing mechanism — a detail that passed without significant analysis but that carries broad implications. Adjusting the pricing formula for a 9-million-bpd pipeline feeding a Red Sea port could affect benchmark references used by Gulf producers whose crude competes with Arab Light in Asian markets. Kuwait and Qatar, if they joined, would be directly implicated in those adjustments. The pricing renegotiation may prove as complex as the engineering.

Abu Dhabi Is Already Building Its Own Bypass

The UAE offers an instructive comparison. The UAE has completed about half of a new west-east pipeline to Fujairah on the Gulf of Oman that will double the existing line’s 1.8 million bpd capacity when it opens next year, according to Reuters. Unlike Yanbu, Fujairah is not covered by the Houthi blockade declaration. The port sits on the Indian Ocean side of the chokepoint, not within the approaches of another.

The Abu Dhabi bypass exits outside both chokepoints. Saudi Arabia’s bypass routes around one chokepoint and into the contested approaches of another.

The difference is that Abu Dhabi’s new line is due to open next year, while the Saudi expansion is still at the preliminary-talks stage.

The Fiscal Arithmetic

Saudi Arabia’s first-quarter 2026 deficit was SAR 125.71 billion. The 2026 budget had projected a full-year deficit of SAR 165.4 billion. Crude prices carry a war premium, but it has not translated into fiscal relief because of the volume problem: Saudi exports through eastern terminals have been curtailed by the Hormuz disruption, and the Yanbu corridor that absorbed the redirected flow now faces the Houthi embargo.

The expansion would cost “billions of dollars,” according to one source cited by Reuters — the only cost guidance in that report.

The war premium that was supposed to buoy revenues has been offset by the volume losses the war itself created. Aramco’s August Arab Light official selling price for Asian buyers was set at negative $1.50 versus the Oman/Dubai benchmark — a signal that even with elevated crude prices, Saudi barrels are being discounted to compete for cargoes that can no longer follow their traditional shipping routes.

The expansion, then, is capital expenditure that will not generate a single additional barrel of revenue for years, committed at a moment when the kingdom is running a deep deficit and the port at the far end of the pipeline sits inside the Houthi blockade zone. Riyadh is either betting that the Houthi embargo will fail and the Red Sea corridor will reopen as the primary Saudi export route — a bet with fiscal consequences if it is wrong — or it is proceeding with an infrastructure plan that predates the blockade and has not been re-evaluated in light of it.

Neighbours’ interest suggests the former reading. The absence of any reported port expansion suggests the latter. A pipeline expansion without a matching port plan would be a planning document that has not been updated.

Both readings terminate at the same place: the first barrel the expansion carries is years away. Every barrel between now and then must move through infrastructure that either already exists and is contested, or that was built for a threat environment two chokepoints simpler than the one Saudi Arabia faces in July 2026.

The pipeline’s 7-million-barrel-per-day ceiling also bears on Saudi Arabia’s ceasefire calculus: see what the East-West Pipeline ceiling means for Saudi export revenue.

Frequently Asked Questions

Has Saudi Arabia expanded the East-West Pipeline before?

Yes. Aramco converted a parallel NGL line within the existing pipeline corridor to crude service. The conversion raised capacity from approximately 5 million to 7 million bpd. No new pipeline was laid — the infrastructure already existed in the same right-of-way. Reuters said it was unclear whether the current proposal of up to 2 million bpd would mean upgrading existing infrastructure or building a new pipeline. New pipe would place it in a different construction category, with a longer timeline and higher cost.

Could Saudi Arabia build a new Red Sea export port alongside Yanbu?

A new Red Sea crude export terminal of comparable scale would require environmental assessments, land acquisition, breakwater construction and tank farm development, and would take years. No such project has been announced or, based on available reporting, discussed in the current round of negotiations.

What happens to Kuwaiti or Qatari crude loaded at Yanbu under the Houthi embargo?

Saree’s July 20 declaration was aimed at Saudi Arabia, and reports said it did not specify what the embargo would cover. A Kuwaiti or Qatari cargo loaded at Yanbu and transiting Bab al-Mandeb southbound would follow the same route as a Saudi one. The embargo risk could extend to any GCC producer that uses the Yanbu corridor.

What is the Iraqi Pipeline in Saudi Arabia, and could it supplement the Petroline?

The Iraqi Pipeline in Saudi Arabia, known as IPSA, is not part of the expansion talks Reuters reported. Bringing an idle line back into service would require comprehensive inspection, probable segment replacement and a bilateral agreement between Saudi Arabia and Iraq. Iraqi crude moved across Saudi territory to the Red Sea would face the same blockade risk as Saudi barrels.

The tanker U-turns on July 21 — a VLCC carrying 2 million barrels for China and an Aframax with 700,000 barrels bound for India both reversing for Suez — provided the first commercial evidence of the blockade’s effect on Yanbu. The Xin Long Yang, initially diverted, later reapproached Bab al-Mandeb, Gulf News reported on July 23.
