Key Takeaways
- Saudi Arabia’s East-West pipeline was running at 35% utilization before the Hormuz crisis — leaving 4.5 million b/d of theoretical bypass capacity effectively dormant
- Goldman Sachs estimated only ~900,000 b/d was actually rerouted in the first four days of disruption, against a theoretical ceiling of 3.6 million b/d on the Saudi line alone
- The IEA’s 3.5-5.5 million b/d “alternative pipeline capacity” figure is a nameplate number, not an operational readiness number — a critical distinction every energy security model has conflated
- The IPSA pipeline (Iraq to Saudi Arabia, 1.65 million b/d design capacity) has been mothballed since 1990 and was not reactivated as of March 2026
- The correct Hormuz disruption risk premium is derived from demonstrated utilization rates (35%/75%), not nameplate capacity — a structural mispricing across virtually every current energy security model
What Is Hormuz Bypass Capacity?
Bypass capacity refers to pipeline infrastructure designed to move Gulf oil and gas to export terminals without transiting the Strait of Hormuz. The two primary active bypasses are Saudi Arabia’s East-West Crude Pipeline (Petroline) running from the Eastern Province to Yanbu on the Red Sea, and the UAE’s Habshan-Fujairah pipeline (ADCOP) running to the Gulf of Oman. A third pipeline — the Iraqi Pipeline through Saudi Arabia (IPSA) — exists at design capacity of 1.65 million b/d but has been inactive since 1990.
Operational readiness is distinct from nameplate capacity. It refers to the volume a pipeline can realistically reroute on short notice, based on current utilization levels, receiving terminal storage availability, and tanker positioning at the outlet port.
Opening
When Amin Nasser told customers on March 9 that Saudi Aramco was “bringing the East-West pipeline to full capacity in the next couple of days,” he was making a promise his infrastructure had spent the last decade refusing to keep.
Nasser had a compelling case on paper. The East-West Petroline was designed for 5 million barrels per day (b/d) and upgraded to a stated 7 million b/d. The UAE’s Habshan-Fujairah pipeline added another 1.5 million. Together: more than enough to absorb the 4 million b/d that had disappeared from Hormuz flows after conflict disrupted traffic in early March 2026.
Goldman Sachs measured the reality: 900,000 b/d actually rerouted in the first four days. Against a theoretical ceiling of 3.6 million b/d on the Saudi line alone.
This is not a story about a surprise. It is a story about a security architecture that was never actually tested — because testing it would have meant using it.
The 35% Problem
Before March 2026, Kpler estimated the Saudi East-West pipeline was running at 35% utilization.
That number requires explanation. The pipeline wasn’t broken. It wasn’t sanctioned. It wasn’t awaiting regulatory approval. Saudi Arabia had every operational incentive and logistical ability to run more oil through it. It simply didn’t.
The implicit logic of energy security planning assumes bypass infrastructure is “available” in the way a fire extinguisher is available — unused until needed, then immediately operational. The Goldman data dismantles that assumption. A pipeline running at 35% doesn’t suddenly perform at 100% because a geopolitical crisis demands it. It performs at 35%, plus whatever incremental ramp-up logistics, crew positioning, tanker availability, and storage capacity at the receiving terminal will allow.
The UAE situation was more honest about its limits. The Habshan-Fujairah pipeline was at 75% utilization before the crisis — much closer to genuine operational baseline. That left only 400,000 b/d of incremental capacity. With that constraint baked in, ADNOC’s March 6-7 announcements about “maintaining supply continuity” were technically accurate and practically underwhelming. Total UAE oil flows in March were tracking toward 2.21 million b/d — less than half of February’s volume, the lowest since June 2016.
The combined pipelines that were supposed to make Hormuz manageable were delivering, at their best, roughly 1.5 million b/d in incremental rerouted supply against a 4 million b/d disruption.

What the Conventional Narrative Gets Wrong
The “protect the Strait” framework has dominated US security planning, Gulf diplomatic architecture, and energy investor risk modeling for forty years. Its logic is internally coherent: Hormuz is the chokepoint, so securing Hormuz secures the supply.
The March 2026 data reveals a different failure mode — one the framework was structurally unable to see.
Securing the Strait is a military problem. Pipeline underutilization is a commercial and political problem. The Gulf states had every incentive to route significant volumes through their bypasses for decades. The East-West pipeline wasn’t kept at 35% because of an engineering constraint. It was kept there because Hormuz was cheaper, more convenient, and — until it wasn’t — perfectly reliable.
Energy security investment, in other words, crowded out energy security preparedness. The same economics that made Hormuz indispensable also made the bypass redundant enough to atrophy.

The IPSA Ghost
The most blunt confirmation of this argument sits in the data: the Iraqi Pipeline through Saudi Arabia (IPSA) — 1,568 km, 1.65 million b/d design capacity — has been mothballed since 1990.
Thirty-six years. No verified reporting of reactivation as of March 2026.
The IPSA pipeline is not a rounding error. At design capacity, it would represent roughly 8% of what was lost when Hormuz flows fell from 20.8 million to 16 million b/d. Instead, it is infrastructure archaeology — a monument to the proposition that bypass capacity only matters if someone is paid to maintain it.
The three pipelines together — Saudi East-West, UAE Habshan-Fujairah, and IPSA at design capacity — could theoretically move 10.15 million b/d. Actual rerouted flow in the immediate crisis period: under 1.5 million b/d on the most generous reading.
The gap between theoretical and operational capacity isn’t a technical problem that more investment solves. It is a structural consequence of decades of treating bypass infrastructure as insurance that would always pay out on demand.
What Investors and Policymakers Are Pricing Wrong
The current market response is pricing Hormuz as the variable. The disruption is the shock; bypass capacity is the buffer; recovery timeline is the question.
The data suggests the pricing model has the causality inverted.
Bypass operational readiness should have been the leading indicator of energy security resilience. Instead it was unmeasured, because no framework existed to measure it. The IEA’s own estimate of combined alternative pipeline capacity — 3.5 to 5.5 million b/d — is a capacity number, not a readiness number. Those are different quantities, and conflating them produced a false sense of systemic buffer.
The practical implication for investors: the correct risk premium for Hormuz disruption is not derived from pipeline nameplate capacity. It is derived from demonstrated operational utilization rates. At 35% and 75% respectively, the two primary bypasses had a combined actual spare capacity of roughly 1.5 to 2 million b/d — not 6.5 to 7 million b/d. That is a structural underestimate in every energy security model that used the theoretical ceiling.
For policymakers: the question worth asking is not “how do we protect the Strait?” The question is “why have we allowed the systems designed to make the Strait less critical to atrophy toward irrelevance?”

Scenarios
Scenario 1: The Pipeline Ramp (Probability: 40%)
Saudi East-West achieves 60-70% utilization within 30-45 days. Real rerouted volumes reach 2.5-3 million b/d. Spot markets stabilize, but structural undersupply persists for Qatar LNG customers into Q2 2026. Asian buyers — South Korea, India, Bangladesh, Thailand — pay $20+/MMBtu for spot cargoes throughout the adjustment period.
Implication for investors: Medium-term price normalization. Position for spread compression in Q3.
Scenario 2: The Utilization Ceiling (Probability: 45%)
Pipeline ramp stalls at 45-50% utilization due to tanker positioning constraints at Yanbu and Fujairah storage saturation. Real rerouted volumes plateau at 1.5-1.8 million b/d. The 4 million b/d Hormuz deficit cannot be meaningfully offset. Brent structural premium persists through Q2. Asian LNG buyers complete structural diversification away from sole reliance on Qatari supply.
Implication for investors: Extended premium. Review LNG contract counterparty exposure.
Scenario 3: Commercial Logic Reasserts (Probability: 15%)
The crisis resolves faster than current assessments suggest — not because pipelines perform, but because commercial pressure on Iran from China (80% of Qatar’s LNG flows to Asia) forces a faster Hormuz reopening than military logic alone predicts. China has already pressed Iran directly to keep the Strait open. Bypass underperformance becomes a footnote rather than a structural lesson.
Implication for investors: Sharp reversal. Spike positions carry significant downside if Chinese mediation accelerates.
Why This Matters
“The bottleneck wasn’t the Strait. It was that no one had seriously operated the bypass at scale since the last time it mattered.”
The energy security architecture built around Hormuz protection has spent forty years solving for the wrong constraint.
The vulnerability was never whether the Strait could be disrupted. It was always whether the bypass systems designed to absorb that disruption had been maintained at operational scale. A pipeline at 35% utilization is not a backup. It is a memory of a backup.
The LNG situation is an accelerant. Japan’s 27-year QatarEnergy supply agreement and Mitsui’s minority stake negotiations — both confirmed at the LNG 2026 Doha conference — reflect long-term confidence in Qatari supply continuity. If the bypass infrastructure performance of March 2026 becomes the reference case, that confidence may need a significantly larger risk adjustment than any of those agreements currently contain.
Policy Recommendations
For energy investors: Reprice Hormuz disruption risk using operational utilization rates (35%/75%), not nameplate capacity. The real buffer was never 6.5-7 million b/d. It was 1.5-2 million b/d.
For corporate strategists: Review LNG supply contracts for force majeure clauses and alternative sourcing provisions. QatarEnergy’s force majeure declaration on March 4 demonstrates this is not a theoretical risk.
For emerging market officials: Countries with high Qatar LNG dependency — South Korea, India, Bangladesh, Thailand — should treat the spot procurement crisis as a structural signal, not a temporary disruption. Diversification decisions made under emergency conditions are rarely optimal.
Bottom Line
Hormuz was the headline. The bypass capacity gap is the story.
Every energy security model that used nameplate pipeline capacity as its resilience metric was, in practice, overstating the world’s ability to absorb exactly this disruption. The data is now public. The analytical framework needs to catch up.
Frequently Asked Questions
Q: Why did Saudi Arabia’s bypass pipeline fail to absorb the Hormuz disruption?
The Saudi East-West pipeline was operating at only 35% utilization before the crisis. A pipeline at that utilization level cannot reroute at full capacity on short notice. Goldman Sachs estimated that only ~900,000 b/d was actually rerouted in the first four days, against a theoretical ceiling of 3.6 million b/d. The constraint was not capacity — it was operational readiness: tanker positioning at Yanbu, receiving terminal storage, and crew logistics all required time to scale.
Q: What is the difference between pipeline nameplate capacity and operational readiness?
Nameplate capacity is the maximum volume a pipeline is engineered to carry under ideal conditions. Operational readiness is the volume it can realistically reroute on short notice based on current utilization, available storage at the outlet terminal, and tanker availability at the export port. The IEA’s widely cited figure of 3.5-5.5 million b/d for Gulf bypass alternatives is a nameplate number. The operational readiness figure in March 2026 was closer to 1.5-2 million b/d.
Q: How much oil normally flows through the Strait of Hormuz?
In the first two months of 2026, flows averaged 20.8 million barrels per day — approximately 20% of global petroleum liquids consumption and 26.6% of global seaborne oil trade. By early March 2026, Kpler vessel-tracking data showed flows falling to approximately 16 million b/d following the conflict with Iran, a reduction of roughly 4 million b/d.
Q: What is the IPSA pipeline and why does it matter?
The Iraqi Pipeline through Saudi Arabia (IPSA) is a 1,568 km pipeline running from Al-Zubair, Iraq to Yanbu, Saudi Arabia with a design capacity of 1.65 million b/d. It has been mothballed since 1990 following the Gulf crisis and was not reactivated as of March 2026. Its continued inactivity illustrates the central argument: bypass infrastructure that is not actively maintained cannot perform when needed.
Q: What should energy investors do differently after the March 2026 Hormuz disruption?
Investors should recalibrate Hormuz disruption risk models to use pipeline operational utilization rates rather than nameplate capacity. At pre-crisis utilization rates of 35% (Saudi) and 75% (UAE), the real incremental bypass buffer was approximately 1.5-2 million b/d — not the 6.5-7 million b/d figure derived from nameplate capacity. LNG contract counterparty exposure should also be reviewed given QatarEnergy’s March 4 force majeure declaration at Ras Laffan.
Q: Could the Northern Sea Route replace Hormuz LNG flows?
No. The Northern Sea Route (NSR) is not a meaningful substitute for Hormuz LNG at present. Total NSR cargo volumes fell 2.3% year-on-year in 2025 to 37.02 million tonnes across all cargo types. Only 5 LNG tanker transits of the full NSR were recorded in 2025. Arctic LNG 2 — the primary NSR LNG project — is only 50% complete and faces critical bottlenecks including a shortage of Arc7 ice-class tankers and sanctions limiting shipyard access.
