The pressure on Hormuz has stripped energy security back to a basic issue: supply volume is not enough. It depends on whether routes remain usable when political risk rises, and on what infrastructure remains available when one passage becomes uncertain. For Europe, the South Caucasus is not a substitute for the Gulf. Its value is narrower: an existing corridor that reduces route concentration in a European system already forced to build redundancy.

Hormuz and the Return of Route Risk

Recent pressure on the Strait of Hormuz has clarified a problem for Europe’s energy security. The issue is whether normal routes remain dependable under political stress. Market expectations now turn on route confidence as much as supply volume: reports of diplomatic movement over the Strait can move oil prices sharply.[1]

Hormuz is not simply a price event; it is a test of route confidence. Tanker movements, insurance costs, producer schedules, storage, and government expectations become parts of the same security problem. The South Caucasus gains significance in this context as one element in Europe’s search for strategic redundancy. It does not substitute for the Gulf, but it reduces route concentration where Europe has few durable alternatives.

“A chokepoint crisis does not merely threaten supply; it tests whether route architecture can still function under political stress.”

The scale of the Hormuz problem lies in the mismatch between normal flows and available alternatives. Nearly 20 million barrels per day of oil moved through the Strait in 2025, while available bypass capacity through Saudi and Emirati routes is estimated at only 3.5 to 5.5 million barrels per day.[2]

Saudi Arabia’s Red Sea route and the UAE’s connection to Fujairah reduce exposure, but they cannot absorb the full volume normally moving through Hormuz. A disruption there is not an ordinary supply adjustment. The price rises because the risk is higher, but this does not produce additional transit capacity. Physical stress, not just market volatility, appears if traffic is impeded for long enough. The same logic extends beyond crude oil, since Gulf LNG flows, especially from Qatar, also depend on the Strait.[3]

Europe’s Redundancy Problem

For Europe, the lesson reaches beyond the immediate Middle East crisis. Since 2022, Europe has reorganized energy policy around diversification: more LNG, more Norwegian gas, more North African supply, tighter storage discipline, demand management, renewables, and selective pipeline diversification. In 2025, Norway supplied 31 percent of EU gas imports, the United States 26 percent, North Africa 13 percent, and Azerbaijan and Qatar 4 percent each; LNG rose from 20 percent of EU gas imports in 2021 to 45 percent in 2025.[4]

Storage changes the problem from another direction. It does not diversify origin, but it changes the timing and political exposure of supply. Fuller storage, multiple LNG terminals, functioning interconnectors, and disciplined winter demand do not make the system invulnerable. It has more ways to absorb a shock without converting price pressure immediately into physical scarcity.

The numbers describe a system already being redesigned. Europe’s energy security now depends on who supplies energy, how it moves, through which corridors, under what political conditions, and with what reserve capacity if one route becomes unreliable.

The South Caucasus Corridor

South Caucasus energy is already embedded in physical infrastructure. The Southern Gas Corridor (SGC) links the Caspian basin to Europe through the South Caucasus Pipeline (SCP) across Azerbaijan and Georgia, the Trans-Anatolian Natural Gas Pipeline (TANAP) across Türkiye, and the Trans-Adriatic Pipeline (TAP) across Greece and Albania, with the Adriatic route into Italy.[5] This is not a line on a map. It crosses producing territory, mountain transit, Turkish infrastructure, Balkan and Adriatic segments, and the Italian entry point into the European gas system.

The South Caucasus thus has a regional role. Azerbaijan is the production and political anchor; Georgia and Türkiye are also part of the route logic. The corridor’s strategic significance lies in its function as a non-Hormuz, non-Russian, pipeline-based route from the Caspian to European markets. Once route reliability becomes a policy criterion, the states along that corridor become part of Europe’s security architecture.

Azerbaijan will replace neither the Gulf nor the volumes Europe lost from Russia. Its importance is more limited, and therefore more credible. Azerbaijani gas already reaches European markets through an established pipeline system. Supplies to the EU have grown since 2021, SOCAR’s European reach has widened, and Azerbaijan supplied 12.5 billion cubic meters of natural gas to EU member states in 2025.[6]

The 2022 EU–Azerbaijan energy memorandum gave the relationship a clear policy framework, aiming to increase SGC capacity toward at least 20 billion cubic meters annually by 2027 while linking gas cooperation to renewables, methane reduction, and the wider energy transition.[7] Azerbaijani gas remains a relatively small part of Europe’s total import balance, but it is especially important in certain national or regional markets such as Italy, Greece, Bulgaria, and other Balkan and south-central European markets.

This pipeline gas moves through established corridors and does not compete for LNG cargoes, tanker availability, regasification slots, or crisis-driven spot prices. It can also help preserve storage during a winter or route shock. Azerbaijan’s deliverable gas can significantly alter the stress level for individual countries, particularly when other routes are congested or exposed.

Europe’s Hard Policy Choice

That is why policy must be implemented as investment discipline. Enabling conditions must be real for the SGC’s role to expand. More Caspian gas requires upstream availability, expanded transmission capacity, bankable demand, financing, and long-term commercial commitments. TAP’s first expansion is modest, adding 1.2 billion cubic meters per year from 2026 under long-term contracts. Further growth depends on market tests and infrastructure investment.[8]

“Strategic redundancy becomes real only when political interest is converted into contracts, capacity, financing, and usable routes.”

Pipeline expansion does not follow from political appetite alone. Capacity is booked, financed, built, and supplied through decisions that have to outlast a single crisis cycle. Buyers, producers, and transmission operators need durable demand to justify investment.

The constraint applies throughout the corridor, including upstream and transit segments such as the SCP, where any larger expansion claim requires careful capacity assessment. Strategic redundancy cannot be obtained by declaration. Europe has to support the contractual and regulatory conditions under which additional reliable routes can be expanded. That is the hard edge of redundancy policy.

The Caspian Option

Discussions of future gas deliveries from Turkmenistan, green-energy corridors, electricity links, and deeper Caspian–European coordination belong to the same strategic logic: Europe is looking for routes that diversify not only suppliers, but also political pathways.[9] These projects all face the same limiting conditions: infrastructure, financing, market integration, and the conversion of political interest into bankable commitments.

These possibilities do not offer a near-term substitute for Gulf flows. They show instead that the SGC could become a wider connectivity platform, provided European policy moves beyond declarative interest toward practical support. Corridor infrastructure creates options; it does not create them automatically. For Europe, the value of that prospect lies in optionality, not in immediate volume.

The immediate Hormuz shock may recede, but the strategic lesson will remain. The episode reinforces a lesson already visible since 2022: energy security has again become a question of physical routes, political reliability, and redundancy under stress. South Caucasus energy cannot remove Europe’s exposure to global chokepoints, but it can reduce the brittleness of Europe’s energy system at the margin where real infrastructure matters. It should be treated as part of Europe’s route-security strategy after Hormuz. For the EU and its member states, interest in the corridor now has to become practical and financial support.
