Abstract
Instability in the Strait of Hormuz, a critical maritime artery through which approximately 20% of the world’s oil and a significant share of Liquefied Natural Gas (LNG) transit, represents a severe vulnerability for global civil aviation. This paper analyzes the systemic implications of energy flow disruptions, highlighting the structural limits of European energy independence, price multipliers, airline response strategies, and long-term perspectives related to Sustainable Aviation Fuels (SAF).

Introduction
The stability of global civil aviation is facing a new phase of stress, comparable to the energy crises of 2008 and the operational distortions of the post-pandemic recovery. Persistent instability in the Strait of Hormuz impacts not only the price of crude oil but also the physical availability of jet fuel, directly affecting the resilience of the entire aviation ecosystem.
1. Structural Limits of European Energy Independence
- Middle Distillate Dependency: Europe suffers from a structural deficit in jet fuel production, relying heavily on imports.
- Supply Chain Vulnerability: A significant portion of the European supply chain is tied to Middle Eastern refining hubs (e.g., Kuwait, Saudi Arabia, UAE).
- Refining Capacity: Current European refining capacity is near saturation and is not optimized to maximize jet fuel yields.
- Industrial Reconversion: The timeframes required for industrial reconversion are incompatible with short-term geopolitical shocks.
2. Price Multipliers: Beyond Supply and Demand
- Global Arbitrage: Realignment of flows toward high-growth economies (China and India) forces European buyers into competitive bidding.
- Logistical Risk Premium: A sharp increase in insurance premiums and maritime freight costs for tankers operating in high-risk zones.
- Operational Rerouting: Flight paths avoiding sensitive airspaces result in longer flight times, leading to double-digit increases in fuel consumption per trip.
3. Carrier Response: Rationalization and Capacity Discipline
- Selective Capacity Reduction: Strategic removal of frequencies on low-margin or non-profitable routes.
- Accelerated Fleet Renewal: Expediting the phase-out of older, less fuel-efficient aircraft.
- Dynamic Pricing: Aggressive implementation of variable fuel surcharges to offset operational volatility.
4. Summer 2026 Outlook: Controlled Stress Scenarios
- Price Pressure: Significant fare increases on high-density leisure routes.
- Secondary Hub Vulnerability: Risk of localized fuel shortages at smaller airports, leading to increased "fuel tankering" (carrying extra fuel from departure), which further inflates total consumption.
- Connectivity Contraction: A reduction in peripheral connectivity, particularly within the low-cost carrier (LCC) segment.
5. SAF as a Structural Response: The Europe–Africa Axis
- Sustainable Production: Leveraging renewable energy and biomass through dedicated industrial infrastructure.
- Strategic Partnerships: Identification of African nations (e.g., Morocco, Egypt, Namibia) as key partners due to high renewable energy potential and geographical proximity.
- Scalability Constraints: A 3–5 year window for plant commissioning, with longer timelines to achieve industrial-scale volumes.
- Bankability Conditions: The need for regulatory stability and long-term "off-take" agreements to secure necessary investments.
Conclusions
The crisis in the Strait of Hormuz underscores the structural vulnerability of civil aviation, which remains dependent on a globalized and inflexible energy supply chain.
- Short-term: Alternatives are limited and lack immediate scalability.
- Medium-to-long term: The development of SAF and geographical diversification of production are mandatory for survival.
The industry is facing a paradigm shift: operational efficiency and energy security have transitioned from environmental goals to essential conditions for systemic resilience.
