Executive Summary

The Strait of Hormuz represents one of the most critical chokepoints in the global energy system.

Approximately 20 million barrels per day (mb/d) of crude oil and petroleum liquids transit through this narrow corridor, alongside a substantial share of global LNG volumes.

This paper presents a structured stress-test scenario of a full Hormuz closure.

The analysis demonstrates that while partial mitigation exists — most notably via Saudi Arabia’s East–West pipeline — the global energy system remains fundamentally constrained not by resource availability, but by transport infrastructure and route security.

A net supply loss of 12–13 mb/d (approximately 12–13% of global supply) would produce a price shock in the range of $180–$300+/bbl, with cascading second-order effects across refining, gas markets, and the broader global economy.

In a chokepoint-constrained world, the value of hydrocarbons is determined not only by their geological abundance, but by their deliverability.

SECTION 1

Global Energy System Baseline

Understanding the magnitude of a Hormuz disruption requires establishing the current operational baseline. The following parameters define the system’s dependency on this corridor.

TABLE 1 — KEY SYSTEM PARAMETERS (2025/2026 BASELINE)

PARAMETER	VALUE / ESTIMATE
Global oil demand	~102 mb/d
Hormuz oil & liquids transit	~20 mb/d
Hormuz share of global supply	~19–20%
LNG share transiting via Hormuz	20–25% of global LNG
OPEC+ spare capacity (total)	~3–5 mb/d
Spare capacity inside Gulf (constrained)	~2–4 mb/d

A critical structural vulnerability is that a large portion of available spare capacity is geographically located within Gulf producer states — rendering it largely inaccessible during a Hormuz closure event.

SECTION 2

Scenario Definition: Full Closure

This stress test models a complete cessation of tanker passage through the Strait — the most severe but analytically instructive case. The scenario parameters are defined as follows:

No tanker passage through the Strait of Hormuz — military interdiction or mine deployment assumed
Conflict-driven insurance withdrawal from the war risk market, effectively grounding commercial shipping
Maximum utilisation of all available alternative pipeline and overland infrastructure
Strategic Petroleum Reserves (SPRs) activated across IEA member states
Duration: modelled on a 90-day sustained closure — sufficient to generate structural market dislocation

⚠

ANALYTICAL NOTE

The SPR buffer of IEA members covers approximately 1.4 billion barrels in aggregate — providing roughly 14 days of full Hormuz replacement capacity, or a partial buffer of 30–40 days at reduced drawdown rates. It mitigates but does not eliminate shock.

SECTION 3

Supply Shock Quantification

Against the 20 mb/d at risk, the following alternative infrastructure represents the realistic mitigation capacity available within a 30–60 day activation window.

TABLE 2 — ALTERNATIVE ROUTE CAPACITY ASSESSMENT

ALTERNATIVE ROUTE / INFRASTRUCTURE	CAPACITY (MB/D)	CONSTRAINTS
Saudi Arabia East–West Pipeline (Petroline)	~5.0	Currently underutilised; pump & terminal upgrades needed
UAE Fujairah Pipeline (ADCO/ADNOC)	~1.5	Operating at partial capacity; bypass capacity confirmed
Iraq–Turkey Kirkuk–Ceyhan Pipeline	~0.5	Subject to geopolitical friction; historically unreliable
Other overland / rail / minor routes	~0.5	Marginal and slow to mobilise
Total Mitigation Capacity	~7.0–8.0 mb/d	Upper bound under optimistic assumptions

TABLE 3 — NET SUPPLY SHOCK SUMMARY

PARAMETER	VOLUME (MB/D)
Volumes at risk (Hormuz transit)	~20
Maximum mitigation (all alternatives)	~7–8
Net supply loss to global markets	~12–13 mb/d
As percentage of global supply	~12–13%

This positions a full Hormuz closure as the single largest supply disruption scenario in modern oil market history — exceeding both the 1973 Arab Oil Embargo (~4.3 mb/d) and the 1979–80 Iranian Revolution impact (~5.6 mb/d) in absolute volume terms.

SECTION 4

Price Response Dynamics

Historical and econometric data provide a basis for price response modelling. The following ranges reflect consensus estimates from the IEA, IMF, and independent commodity research — adjusted for current market structure.

TABLE 4 — ESTIMATED BRENT CRUDE PRICE RESPONSE BY SUPPLY SHOCK MAGNITUDE

SUPPLY SHOCK (%)	VOLUME LOST (MB/D)	ESTIMATED BRENT RANGE	SCENARIO ANALOGUE
~2–3%	~2	$95–$115/bbl	Libya disruption 2011
~5%	~5	$120–$150/bbl	Large OPEC+ cut scenario
~10%	~10	$150–$220/bbl	Combined Gulf disruption
~12–13%	~12–13	$180–$300+/bbl	Full Hormuz Closure

It bears emphasis that these ranges represent fundamental supply-demand effects alone. Market panic, speculative positioning, war-risk insurance repricing, and logistics bottlenecks systematically amplify realised prices beyond fundamental equilibria — particularly in the initial weeks of disruption.

Oil price formation in a disruption scenario is not governed by equilibrium — it is governed by fear of non-delivery. The first bid is never the last.

SECTION 5

LNG and Gas Market Disruption

The Strait of Hormuz is simultaneously a critical LNG corridor — channelling exports from Qatar (the world’s second-largest LNG exporter), along with volumes from the UAE and Iran.

A closure would impose severe disruptions on global gas markets, with regionally differentiated impacts.

TABLE 5 — REGIONAL GAS MARKET IMPACT ASSESSMENT

REGION	LNG DEPENDENCY	PRIMARY IMPACT	RISK LEVEL
Europe	Moderate-High	Extreme TTF price escalation; demand destruction	Critical
Japan & South Korea	Very High	Severe supply competition; LNG spot prices spike	Critical
China	High	Pipeline rerouting possible but insufficient; price shock	High
India	Moderate	Competitive bidding disadvantage; industrial curtailment	High
Industrial Sectors (global)	Varies	Shutdown risk: fertilisers, petrochemicals, aluminium	High

Gas markets — unlike oil — lack the geographic arbitrage flexibility available through crude re-routing. LNG infrastructure is point-to-point, with limited vessel re-direction capacity and no equivalent pipeline bypass. The transmission channel of economic disruption through gas is therefore faster and more severe than through crude oil markets alone.

SECTION 6

Systemic Second-Order Effects

Beyond immediate price impact, a sustained Hormuz closure propagates through the global economy via multiple structural channels.

Refinery Configuration Constraints

A substantial share of global refinery capacity is configured to process medium-to-heavy sour crude grades characteristic of Gulf production. Light sweet Atlantic Basin crudes — the natural replacement — cannot be fully substituted without significant investment in refinery adaptation. This crude quality mismatch introduces a supply-side friction independent of volume.

Strategic Reserve Limitations

IEA member strategic reserves provide meaningful but time-limited relief. At maximum coordinated drawdown rates (~4 mb/d), SPR coverage provides approximately 30–40 days of partial buffer. Beyond this window, market conditions deteriorate structurally unless alternative supply routes are fully operational.

Shipping and Insurance Markets

War-risk insurance premiums surge immediately, potentially exceeding the cost of cargo on marginal routes
Tanker diversion costs increase effective landed price of alternative-route crude by $15–$40/bbl
Port congestion at Fujairah, Oman, and Red Sea terminals constrains throughput capacity
Crew willingness to transit adjacent waters contracts, further reducing effective shipping capacity

SECTION 7

Winners and Losers: A Geopolitical Redistribution

A Hormuz closure is not uniformly destructive. It produces a structural redistribution of value across the global energy system, defining a new geopolitical hierarchy of energy security.

▲ RESILIENT PRODUCERS — STRUCTURAL PREMIUM

United States (Permian, GoM)
Brazil (Pre-Salt, deepwater)
Norway (North Sea)
Guyana (Stabroek Block)
Suriname (in 2028, Block 58; Block 52)
Canada (oil sands, Atlantic)

▼ HIGHLY EXPOSED CONSUMERS — ACUTE VULNERABILITY

Japan & South Korea
India
China
European Union
Pakistan & Bangladesh
Southeast Asian manufacturing economies

Atlantic Basin producers gain a structural premium precisely because their logistics chains are entirely chokepoint-free.

This geographic advantage — historically a minor pricing factor — becomes a dominant value driver under disruption conditions. For Guyana and Suriname in particular, this reinforces the strategic case for accelerated monetisation of offshore resources.

SECTION 8

Strategic Interpretation

The global energy system is not constrained by resources — it is constrained by infrastructure and transport vulnerability. Hormuz is not a geological risk; it is a geopolitical one.

Saudi Arabia’s Petroline offers genuine but partial resilience. At full utilisation, it displaces approximately 25% of Hormuz oil volumes — meaningful, but insufficient to prevent systemic shock. It also carries no LNG. The corridor’s vulnerability is therefore structural, not incidental.

The key strategic inference is not simply that Hormuz is risky. It is that the global energy system has knowingly concentrated risk in a single 21-nautical-mile passage, and has failed to invest in proportionate redundancy. This is a systemic design failure — not an unforeseen event.

SECTION 9

Implications for Energy Strategy

The Hormuz stress test produces a set of durable strategic imperatives that apply at the level of corporate asset strategy, national energy policy, and multilateral system design.

Infrastructure redundancy must be priced as a strategic asset — pipeline bypass capacity, deepwater export terminals, and FLNG offshore solutions carry a geopolitical option value that traditional DCF analysis systematically underestimates.
Chokepoint exposure must be explicitly priced into asset valuations — discount rates applied to Gulf-linked assets should incorporate a geopolitical risk premium commensurate with Hormuz dependency.
Regional energy system formation accelerates — the strategic case for autonomous supply corridors (West Africa to Europe, Guyana/Suriname to Atlantic markets) strengthens structurally under this scenario.
Gas requires earlier infrastructure certainty than oil — due to LNG’s inflexibility, gas monetisation decisions demand a longer-term commitment to route security than equivalent oil developments. FLNG and Gas-to-Shore hybrid solutions that bypass chokepoints carry premium strategic value.
Sovereign energy security policies must stress-test chokepoint scenarios — nations that fail to model Hormuz closure as a base-case planning scenario are not managing geopolitical risk; they are deferring it.

SECTION 10

Conclusion

A full Hormuz closure would represent one of the most severe and structurally disruptive energy supply events in modern history. The analysis presented here demonstrates that net supply losses would reach approximately 12–13 mb/d, driving crude prices into a range of $180–$300+/bbl and simultaneously triggering acute disruption across global LNG and gas markets.

The central lesson is not merely that Hormuz is dangerous — that has been known for decades. It is that the global energy architecture has accepted an extraordinary level of concentrated route dependency, without commensurate investment in structural redundancy. The stress test exposes this as a systemic vulnerability, not a residual risk.

For producers, investors, and policymakers alike, the Hormuz scenario reframes the fundamental value proposition of energy assets: location and logistics matter as much as subsurface resource quality. In a world of increasing geopolitical fragmentation, chokepoint exposure is no longer an externality — it is a central variable in asset value.

The most valuable barrel is not the one that exists — but the one that can always be delivered.

SECTION 11

Alignment with Shell Energy Scenarios

11.1 Scenario Framework Context

Shell’s scenario framework — particularly the Waves, Islands, and Sky 1.5 pathways — provides a structured qualitative lens through which systemic energy risks can be mapped and interpreted. These scenarios are not forecasts. They are exploratory models designed to stress-test strategic assumptions under varying geopolitical, economic, and technological conditions.

11.2 Scenario Mapping of a Hormuz Closure

TABLE 6 — SHELL SCENARIO MAPPING: HORMUZ CLOSURE RELEVANCE

SHELL SCENARIO	HORMUZ CLOSURE PROBABILITY	STRUCTURAL ALIGNMENT
Islands	High	Fully consistent — geopolitical fragmentation, energy nationalism, route insecurity
Waves	Low–Moderate	Temporary disruption; market and institutional mechanisms absorb shock rapidly
Sky 1.5	Low	Reduced fossil dependency limits systemic impact; transition investment accelerates

A full closure aligns most closely with the Islands scenario, characterised by geopolitical fragmentation, the regionalisation of supply chains, and the dominance of national energy security over global market efficiency.

11.3 Structural Characteristics: Islands Scenario

Energy security systematically dominates economic optimisation in national policy
Trade routes become contested, unreliable, or subject to political leverage
Regional energy blocs with autonomous supply corridors emerge and solidify
Infrastructure redundancy transitions from cost item to strategic priority
Trust-based multilateral coordination erodes; bilateral agreements dominate

Within this framework, a Hormuz disruption is not an outlier event but a logical structural manifestation of systemic fragmentation — a predictable consequence of the scenario’s underlying dynamics.

11.4 Model Implications and System Predictions

Shell’s scenario logic does not predict specific events such as a Hormuz closure. However, it does anticipate the conditions that make such events more probable and more severe. Specifically, the Islands scenario would lead analysts to expect:

Increased frequency and severity of supply disruptions linked to geopolitical deterioration
Persistent oil price volatility with embedded geopolitical risk premiums
A strategic shift from “just-in-time” to “just-in-case” energy infrastructure design
Acceleration of regional energy autonomy investments, including chokepoint bypass solutions
Reduced effectiveness of multilateral responses (IEA SPR coordination) under fragmented governance

11.5 Critical Insight

A Hormuz closure is not an outlier within future energy scenarios — it is a stress test that reveals which scenario the world is already moving toward.

This analysis quantitatively reinforces Shell’s qualitative frameworks by demonstrating the precise magnitude of disruption (~12–13 mb/d supply loss) and the systemic amplification effects that follow. The numbers give flesh to the scenario’s bones.

11.6 Strategic Implication

The convergence of geopolitical fragmentation and energy infrastructure vulnerability suggests that future energy systems will be defined less by the distribution of geological resources and more by logistical resilience, route security, and the strategic geography of export infrastructure.

The transition underway is not only an energy transition — it is a transition from global efficiency to regional resilience.
