Hormuz Has 20 mb/d of Traffic and 2.7 mb/d of Bypass

Roughly 20 million barrels of crude and condensate move through the Strait of Hormuz every day. The sum of all existing pipeline bypass capacity that could actually be mobilised in an emergency sits somewhere around 2.7 million barrels per day. That ratio is the whole story.

This is not a hypothetical vulnerability that might emerge under the wrong conditions. It is a structural engineering reality that has persisted for decades, and every “alternative route” announced over that period has failed to close it. Political leaders and company communications routinely cite pipeline projects as proof of bypass resilience. This piece tests those claims against delivered capacity, not headline capacity.

Here is exactly what the infrastructure can and cannot do, so you can weigh any future disruption headline or bypass announcement against a factual baseline rather than a political one. By the time you finish this, you will hold a working mental model of the numbers, not just a vague sense that the strait matters.

What “bypass capacity” actually means, and why the definition matters

The phrase sounds simple. If a pipeline is rated at 7 million barrels per day, surely that is 7 million barrels of Hormuz traffic it can absorb. The number on the datasheet feels like the answer.

It is not the answer. Three different figures hide inside every pipeline: the rated capacity of the pipe, the operational throughput it actually carries day to day, and the genuine spare capacity left over for emergency rerouting. Only the third number matters in a crisis, and it is almost always the smallest.

Consider the two systems that carry the regional bypass load today. Saudi Arabia’s Petroline runs at roughly 2 mb/d under routine conditions against a ceiling of 4.5-5 mb/d. The UAE’s ADCOP line runs near 1.1 mb/d against a ceiling of 1.5-1.8 mb/d. What is left over, not what the pipe could theoretically hold, is the bypass.

Approximately 20 mb/d transits the Strait of Hormuz. The genuinely available spare bypass capacity that could be mobilised in the first weeks of a crisis sits between roughly 0.5 mb/d and 3.7 mb/d, depending on port and loading constraints.

The reason redundant infrastructure rarely gets built is commercial, not technical. Cross-border pipelines require tens of billions in capital, approvals from multiple governments, and they sit commercially stranded in normal times. Nobody funds an idle asset that only earns its keep during a war.

The bypass capacity gap between official announcements and verified engineering reality has been consistently wider than governments acknowledge, a pattern that holds across every major assessment published through late 2026.

Why port terminals, not pipelines, set the ceiling

Here is the constraint most bypass claims ignore entirely. Petroline is rated at 7 mb/d, but the Yanbu terminal on the Red Sea can only load vessels at 4.5-5 mb/d. The pipe is not the bottleneck. The port is.

A pipeline cannot move oil faster than its terminal can pump it onto ships. Expanding that ceiling means building new berths, adding storage tanks, and upgrading loading arms, each of which adds years and capital to any bypass timeline. When you see a headline pipeline capacity figure, the real question is always what the port at the far end can actually load.

The Petroline port limitations at Yanbu are a documented constraint: while the pipe is rated at 7 mb/d, the terminal’s actual export capability sits between 4 and 4.5 mb/d, confirming that the port, not the pipeline, is the operational ceiling in any bypass scenario.

The two pipelines that exist today, and the one arriving in 2027

Only two systems currently move oil around the strait. Add them up carefully, because the tally you build here is the ceiling everything else is measured against.

Start with Petroline. It runs approximately 1,200 km across Saudi Arabia to Yanbu, rated at 7 mb/d but constrained by the terminal to 4.5-5 mb/d. With roughly 2 mb/d already flowing under normal operations, genuine spare capacity lands at 2-3 mb/d. That is the single largest bypass asset in the region.

Now ADCOP. It runs about 400 km to Fujairah on the Gulf of Oman, sidestepping Hormuz entirely, with a capacity of 1.5-1.8 mb/d. It normally operates near its ceiling at 1.1 mb/d, leaving only around 700,000 b/d of spare capacity.

Add those two together and the current emergency ceiling is modest: at best around 3.7 mb/d, and in tighter loading scenarios far less.

The one genuinely near-term addition is the UAE’s second crude line to Fujairah, running parallel to ADCOP. Because it sits entirely inside the UAE, it carries no cross-border political risk. Construction began in 2025, roughly $3 billion has been invested, and it was reported about 50% complete as of May 2026, with the Fujairah port expanding alongside it.

On completion in early-to-mid 2027, it should add around 1.8 mb/d. Here is the cumulative tally:

1. Current combined spare capacity: up to approximately 3.7 mb/d.
2. Plus the second UAE pipeline: an additional 1.8 mb/d.
3. Total projected bypass capacity by 2027: roughly 5-5.5 mb/d.

Even with that new line online, the combined system covers less than 30% of normal Hormuz traffic. For anyone holding energy assets or supply-chain-exposed positions, that is the verified supply floor: the maximum that could be rerouted within 18-24 months is a small fraction of what a serious disruption would remove.

The five-year horizon: why 12 mb/d on paper is not 12 mb/d in practice

Stretch the timeline to five years and a much larger number appears. Stated ambitions across the region point toward combined bypass capacity of 12-13 mb/d, with Saudi Arabia reportedly weighing an East-West expansion of 1-2 mb/d and a goal of pushing total capacity toward 9 mb/d by the end of 2029. That figure gets cited as evidence the problem is being solved.

Now take it apart. Construction on the Saudi expansion had not begun as of September 2026, so the timeline is aspirational rather than committed. And even a fully realised programme carries a drag most announcements skip over: approximately 3.1 mb/d of that projected capacity is already consumed by normal pre-crisis operations.

Strip out what is already committed and the net new bypass contribution falls to 9-10 mb/d. Against roughly 20 mb/d of Hormuz throughput, that is about half of what a full closure would require, in the best case, in five years.

Iraq’s four routes and why none of them resolve the gap

Iraq is often floated as the missing piece, but its own pre-crisis Hormuz throughput was around 3.6 mb/d, more than the combined Saudi and UAE spare capacity. Each of its four theoretical routes carries a distinct blocking constraint:

• Kirkuk-Ceyhan: design capacity 1.4-1.6 mb/d, but flowing at only about 250,000 b/d as of March 2026 under a one-year extension agreed in August 2026, with no comprehensive Baghdad-KRG revenue-sharing deal in place.
• IPSA: design capacity 1.65 mb/d, inactive since 1990.
• Syria route: proposed at 2-3 mb/d, still in feasibility study, with 3-5 years of construction if ever approved.
• Jordan-Aqaba: proposed at 1-2.5 mb/d, facing financing gaps and an unstable transit corridor.

A pipeline with 1.65 mb/d of design capacity, the IPSA line, has sat idle since 1990. That is the precedent for how regional political disputes strand major infrastructure indefinitely, not for years but for decades.

Building a genuinely new Iraqi network to the Mediterranean would cost around $20 billion and take at least a decade. A US envoy suggested these projects could make Hormuz an afterthought by 2030; regional specialists discount that given the multi-government approvals every route depends on.

The gap between the ambition figure and the engineering reality means that even in 2030, a sustained closure would still produce a supply shock no currently approved or funded pipeline combination could fully absorb. Learning to separate announced capacity from deliverable capacity is the core skill for reading any energy security claim, whether it appears in a government white paper or an investor presentation.

The LNG reality: not a gap but a wall

Oil has an inadequate bypass. Gas has none at all.

Liquefied natural gas (LNG) bypass capacity through the Strait of Hormuz is structurally zero across every planning horizon through 2030. This is not a shortfall to be managed down over time. It is an absolute constraint.

The reason is physical. Natural gas has to be cooled into liquid form to travel by sea, so replacing the maritime route would require both an overland pipeline to a port outside the strait and an entirely new liquefaction terminal at the far end. Neither exists, and neither has been approved.

The exposure numbers make the stakes plain. Around 20% of globally traded LNG passes through the strait. Qatar exported roughly 81.5 Mt in 2025, about 18.7% of global LNG trade, all loaded at Ras Laffan inside the Persian Gulf. Approximately 93% of Qatar’s exports and 96% of the UAE’s transit Hormuz.

There is one gas pipeline in the region, the Dolphin line from Qatar to the UAE and Oman, but it carries gas rather than LNG and has almost no spare capacity. Qatar’s flagship expansions do not change the routing picture:

1. What North Field East and South do: add liquefaction capacity at the existing Ras Laffan facilities.
2. What they do not do: create any alternative export route that avoids the strait.

No alternative gas pipeline or overland route has been approved, financed, or commenced for either Qatar or the UAE, and assessments through late August 2026 confirm that position holds through 2030.

If you buy Qatari or UAE LNG under long-term contracts, this structural zero matters enormously. A serious Hormuz disruption does not reduce your supply; it removes it. That is a qualitatively different risk from the partial-bypass situation on the oil side, and utilities and gas-exposed investors need to price it as such.

US LNG as a Qatari substitute carries its own ceiling: US liquefaction capacity and shipping fleet constraints mean substitution volumes would fall well short of the roughly 81.5 Mt Qatar exported in 2025, even under a fully coordinated emergency response.

The secondary chokepoint problem, and what the price models say

Even the modest oil bypass that does exist comes with a catch. Routing crude through Petroline to Yanbu or through a proposed Jordan-Aqaba line does not remove chokepoint risk. It relocates it.

Oil heading to Asian markets from the Red Sea must still pass through the Bab-el-Mandeb Strait at the mouth of the Red Sea, a corridor already under strain. Rerouted crude shipments through Bab-el-Mandeb climbed to roughly 7.2 mb/d by April 2026 amid regional conflict, showing how fast the alternative congests. Bypassing Hormuz can mean simply concentrating the risk one strait to the west.

Bab-el-Mandeb disruption compounds the problem in a way the headline bypass numbers do not capture: congestion at both chokepoints simultaneously removes the partial offset that pipeline rerouting is supposed to provide.

Partial offsets exist. Full utilisation of spare pipelines combined with Strategic Petroleum Reserve (SPR) releases can soften a shock, though not remove it.

According to modelling attributed to Goldman Sachs, a full one-month closure could add $10-15/bbl, dropping to around $12/bbl with full pipeline use and roughly $10/bbl once SPR releases are factored in. These figures remain unverified independently and should be read as conditional estimates rather than settled numbers.

Separate modelling attributed to the Federal Reserve Bank of Dallas suggests a major closure could push WTI toward $98/bbl in Q2 2026 and reduce global real GDP growth by an annualised 2.9 percentage points for that quarter. That estimate is also unconfirmed and should be treated as one scenario among several.

The exposure is heavily concentrated. Roughly 80% of affected Gulf exports head to Asia, which puts four economies at the front line:

• China: the largest single destination for Gulf crude.
• India: highly import-dependent and price-sensitive.
• Japan: reliant on both Gulf oil and LNG.
• South Korea: similarly exposed across oil and gas imports.

What this converts to for you is calibration, not anxiety. Knowing the bypass ceiling and the secondary chokepoint exposure lets you stress-test energy-linked positions against specific price and GDP scenarios rather than an unquantified geopolitical worry.

What the bypass gap means for the decade ahead

The picture resolves into three tiers. Oil has a modest and slowly improving bypass that remains structurally inadequate. LNG has no bypass at all. And even the oil routes that exist shift concentration risk toward Bab-el-Mandeb rather than eliminating it.

That structure is unlikely to change within any credible planning window. Even a fully realised five-year expansion leaves about 3.1 mb/d pre-committed to normal operations and delivers net new bypass of 9-10 mb/d against roughly 20 mb/d of throughput. History reinforces the caution: bypass announcements reliably follow supply shocks and then stall once prices stabilise, a pattern visible after Suez in 1956, the 1980s Tanker War, and the 2019 Gulf attacks.

So when the next bypass announcement lands, run it through three questions:

1. How much of the stated capacity is genuine spare, and how much is already committed to normal operations?
2. What is the terminal loading constraint at the destination port, and does it cap the headline pipe figure?
3. Does the route bypass Hormuz only to create fresh exposure at Bab-el-Mandeb?

For anyone pricing energy risk over a multi-year horizon, the structural conclusion is that the Hormuz bypass gap is not a problem being solved inside a credible window. Positions built on the assumption that it will be solved are likely mispriced.

Oil shock resilience strategies at the national and portfolio level have evolved since the 1970s, with SPR coordination, demand-side flexibility, and fuel-switching capacity now factored into most serious scenario analyses of a sustained Gulf disruption.
