The recent US and Israeli strikes on Iran have raised significant risks to Europe's energy security, with analysts warning that any extended interruption to liquefied natural gas (LNG) flows from the Middle East could deliver a massive blow. Europe relies on LNG imports for about a third of its domestic demand. A prolonged disruption, potentially caused by the closure of the Strait of Hormuz or a shutdown of Qatari LNG production, would have severe repercussions across the continent.

Immediate Market and Supply Impact

The attack prompted QatarEnergy to shut down production from its giant North Field, though the extent of damage and duration of the halt are unknown. This news caused a fresh surge in European gas prices, with the benchmark TTF price closing more than 35% higher. The Strait of Hormuz is a critical chokepoint, transiting a fifth of global LNG supply. Its closure would immediately tighten global spot availability, forcing Europe into competition with Asian buyers for flexible cargoes—a scenario reminiscent of the 2021-2023 energy crisis.

Europe's Vulnerable Position

Qatar is Europe's third-largest LNG supplier, accounting for 8% of the region's imports in the latter half of last year, behind the US (57%) and Russia (17%). The timing of the conflict exacerbates Europe's exposure, as gas storage levels are currently unusually low. Storage at the end of last month was 46 billion cubic metres, 23% less than the 60 Bcm held at the same point in the previous year. Any import disruption could hinder storage refill operations, increasing pressure on industrial energy costs. Higher gas prices would feed into power prices and industrial margins, potentially triggering renewed coal demand and pressure for demand-side savings, especially if oil and gas prices spike in tandem.

Responses and Strategic Considerations

The European Commission is closely tracking price and supply developments and will convene an Energy Task Force with member states. The UK government stated it is monitoring the situation closely, citing strong and diverse energy supplies. Analysts recommend Europe prepare by:

• Monitoring for possible diversion of LNG cargoes to Asia.
• Developing a gas demand reduction strategy.
• Ensuring more coordinated gas storage refilling operations in the coming months.

Long-Term Outlook and Divergent Views

Over the medium term, global supply could theoretically fill a gap left by prolonged Qatari outages, given 240 million tonnes of new LNG capacity under construction. However, reaching a stable operating state would involve significant price volatility. A short outage would have minimal effects on Europe. Views on securing future energy supplies vary. One perspective emphasizes boosting domestic oil and gas production as more reliable, less carbon-intensive than imported LNG, and less vulnerable to geopolitical disruption. A contrasting view argues that accelerating the transition to renewable energy is essential to durably shield Europe's economy from recurrent external shocks by reducing structural dependence on oil and LNG imports.
