The Iran Conflict and European Energy Security: Short- and Mid-Term Implications

This crisis is the strongest argument yet for accelerating clean-energy deployment as a hard security imperative.

Situation Overview

The US-Israeli strikes on Iran launched on 28 February 2026 have triggered a cascading energy-security crisis with direct consequences for Europe. Tehran’s retaliatory missile and drone salvos have struck Gulf energy infrastructure, disrupted shipping through the Strait of Hormuz. This forced QatarEnergy — operator of the world’s largest single-site LNG export complex — to halt operations at both Ras Laffan and Mesaieed industrial complexes and declare force majeure on contracted cargoes (Bloomberg, CNBC).

Saudi Aramco’s 550,000 bpd Ras Tanura refinery — one of the largest in the Middle East — underwent a precautionary shutdown after debris from intercepted drones caused a fire on March 2; the facility was struck again on March 4 by a drone (no significant damage reported), establishing a pattern of repeated targeting of Gulf energy infrastructure (Bloomberg, Reuters/Zawya).

The Strait of Hormuz has moved from severe disruption to effective closure. On 2 March, a senior IRGC official formally declared the strait closed and threatened to fire on any vessel attempting transit. By 4 March, the IRGC Navy claimed “complete control” of the waterway. Traffic dropped from approximately 70% initially to near-zero by March 1–2; at least five tankers have been struck and two crew killed.

Approximately 3,200 ships — roughly 4% of global tonnage — are idle in the Gulf, with another 500 waiting outside (Clarksons Research). One tanker (Pola) made a rare dark transit with AIS switched off. Major container lines including Maersk and Hapag-Lloyd suspended all Hormuz transits.

Iran does not need to maintain a formal blockade: insurance repricing, electronic interference, and demonstrated willingness to attack vessels create commercial paralysis through self-deterrence (Euronews, Al Jazeera). Roughly 20 million bpd of oil — a fifth of global consumption — and about one-fifth of global LNG trade transit the Strait (Bruegel).

 

Short-Term Impacts (Days to Weeks)

Natural gas is the more acute vulnerability. European benchmark gas prices (Dutch TTF) surged from the low 30s to intraday highs above 63 EUR/MWh — the 52-week range high — though settlement has oscillated between 50–60 EUR/MWh amid extreme volatility.

Goldman Sachs revised its April 2026 forecast to 55 EUR/MWh from 36; Goldman further estimated a month-long Hormuz closure could push European gas prices up 130% from pre-crisis levels (Bloomberg). The QatarEnergy halt is among the most significant unplanned LNG outages in the industry’s history, temporarily removing roughly one-fifth of global LNG export capacity.

Europe enters this crisis in a weaker position than in previous years. EU gas storage stood at approximately 30% of capacity at end-February 2026, well below last year’s levels (roughly 40% at the same point in 2025) (Euronews). German inventories were at ~20.5%, France similarly low. If the Qatari outage persists beyond 30 days, the EU may be forced to trigger the Gas Demand Reduction Plan far earlier than anticipated.

Although Qatar’s direct share in European LNG imports is 12–14%, the indirect impact is far greater: over 80% of Qatari LNG normally goes to Asia, and disruption forces Asian buyers onto global spot markets, intensifying competition for remaining cargoes from the US and Australia. This mirrors the 2022 dynamic: fewer molecules, more buyers, spiralling prices.

On oil, Brent rose to approximately $82/barrel (+6–13% depending on session), with JPMorgan warning a multi-week Hormuz squeeze could push prices above $100 (CNBC). OPEC+’s decision on 1 March to add 206,000 bpd from April is symbolic rather than material: if Hormuz is constrained, production targets offer limited relief — logistics, not quotas, determine deliverable supply (France 24).

OPEC+ spare capacity is concentrated in Saudi Arabia and the UAE (~2.5 million bpd combined per IEA), and both face the same transit risks.

 

Mid-Term Outlook (Weeks to Months)

If the conflict remains limited and Hormuz reopens, a gradual price correction is plausible but not guaranteed. Damage to Qatari LNG infrastructure will require assessment and repair on an uncertain timeline. Saudi Arabia has begun rerouting some crude exports to Red Sea ports to avoid Hormuz, but this offers partial relief at best.

A significant policy signal emerged on 4 March: Norway’s Energy Minister Terje Aasland stated that the Iran crisis could reopen the EU debate over banning Russian gas imports — an implicit acknowledgment that the EU’s phased ban (spot LNG already restricted in early 2026, pipeline gas scheduled for late 2027) may be unsustainable under current conditions (Reuters via Zawya). The EU itself, however, told member states it sees “no immediate effect” on gas supply security — a position at odds with a 75% weekly price spike.

The macroeconomic impact compounds Europe’s fragile recovery. As ING economists warned, the Iran conflict could not have come at a worse time: the eurozone had just emerged from stagnation, and its recovery was already undermined by US tariff uncertainty — meaning Europe now faces an energy shock on top of a trade shock (NL Times).

A sustained $15/barrel oil increase could add roughly half a percentage point to European inflation over 12 months, depending on pass-through dynamics. The ECB, due to publish new projections on 19 March, will likely revise its energy assumptions sharply upward from its December baseline of 29.6 EUR/MWh for gas and $62.5 for crude (Reuters).

China is reportedly pressuring Tehran to keep Hormuz open (Bloomberg) — though Beijing may simultaneously seek discounted Iranian crude via the “dark fleet,” dampening its incentive for full de-escalation. The IEA has signalled readiness to coordinate a strategic petroleum reserves release, noting member states hold over 1.2 billion barrels of emergency stocks (Bloomberg).

 

Escalation Scenarios (as of 4 March)

The appointment of Mojtaba Khamenei as Iran’s new Supreme Leader — reportedly under IRGC pressure — and Tehran’s explicit refusal to negotiate with the United States significantly alter the probability distribution across scenarios. A short conflict lasting two to three weeks, with Hormuz reopening, now appears less plausible: the new leadership signals continuity of confrontation, not de-escalation.

Were it to occur, prices would correct toward 40–50 EUR/MWh and the refill season would be compressed but not derailed. A protracted standoff of four to eight weeks — now the baseline scenario — would sustain prices above 50–60 EUR/MWh, likely triggering EU demand-reduction measures, a coordinated IEA reserve release, and the EU Gas Coordination Group (which convened on 4 March) moving to crisis-response mode.

A regionalization scenario — with direct attacks on Gulf production infrastructure across multiple states — would constitute a systemic shock comparable to 2022, pushing Brent above $100. The repeated drone strikes on Ras Tanura (March 2 and 4) and Iran’s demonstrated willingness to strike Qatari LNG facilities suggest that energy infrastructure has already become an explicit instrument of escalation.

 

Policy Implications for Central Europe

For Central Europe, the Iran crisis arrives on top of an already acute supply disruption. The Druzhba pipeline — the sole conduit for Russian crude to Slovakia and Hungary — has been offline since a Russian drone strike damaged infrastructure near the Brody oil hub on 27 January 2026. Successive restart deadlines have been missed, including the latest on 4 March.

Slovakia declared a national energy emergency; Hungary blocked a EUR 90 billion EU loan to Ukraine until flows resume. Both governments accuse Kyiv of deliberately prolonging the outage, while Ukraine says the pipeline was extensively damaged and repair under ongoing Russian bombardment is dangerous.

The European Commission and EU Council President Costa personally requested inspection access during their 24 February Kyiv visit but were denied on security grounds. On 4 March, Putin met Hungarian Foreign Minister Szijjártó specifically to discuss the Druzhba standoff, with the Kremlin describing Ukraine’s actions as “blackmail.”

Fico-Zelenskyy talks are proposed for March 6 or 9, though prospects remain uncertain (Financial Times, Kyiv Independent, EUobserver).

Slovakia and Hungary thus face a dual supply squeeze unique in the EU: pipeline crude from Russia cut since January, global energy markets convulsed by Hormuz since February. Slovak Deputy Foreign Minister Marek Eštok stated after the extraordinary EU foreign ministers meeting that the combination of Hormuz closure and Druzhba disruption “would directly threaten Slovakia’s energy security” — an official confirmation of the dual-squeeze dynamic (STVR).

Slovakia’s Slovnaft refinery is configured almost exclusively for Russian crude; the alternative Adria pipeline via Croatia remains limited in capacity and politically contested. The Druzhba standoff has already fractured EU solidarity — blocking the 20th Russia sanctions package and the Ukraine aid loan — and the Iran crisis risks deepening this rift by raising the political cost of energy insecurity in Budapest and Bratislava.

This is the first energy crisis of the post-Russia era that originates outside Europe — and it is maritime and system-wide rather than supplier-specific. Post-2022 diversification toward LNG (Swinoujscie, Krk, German FSRUs) reduced dependence on Russia but did not eliminate geopolitical exposure.

If Qatari LNG contracts trigger force majeure and Asian buyers outbid European utilities for spot cargoes, Central European LNG infrastructure risks significant underutilization by late spring. Bruegel has outlined contingency recommendations including coordinated monitoring of LNG cargo diversions to Asia, EU-wide demand reduction, and coordinated storage refill (Bruegel).

For Central European governments, immediate priorities are: resolving the Druzhba impasse through credible international inspection; pre-authorizing demand curtailment playbooks; coordinating LNG procurement against intra-EU bidding wars; and addressing interconnector bottlenecks limiting regasified LNG flows into landlocked markets.

No diversification of hydrocarbon suppliers eliminates geopolitical risk — it merely shifts its geography. This crisis is the strongest argument yet for accelerating clean-energy deployment as a hard security imperative.
