European natural gas prices have climbed to their highest levels since 2023 due to escalating conflicts in the Middle East, reigniting energy security concerns across the continent four years after the onset of the Russia-Ukraine war.

The price of natural gas in Europe has risen 53% since last Friday as shipping through the critical Strait of Hormuz has nearly halted, and attacks by Iran on Qatar have forced the world's second-largest liquefied natural gas (LNG) supplier to suspend production.

Henning Gloystein, an energy expert at Eurasia Group, stated, "This is a double blow. Europe had just emerged from an industrial energy crisis and is now confronting a new one."

On Wednesday, an LNG tanker originally bound for France diverted across the Atlantic towards Asia, marking the first vessel to change course and indicating heightened competition from Asian economies for available supplies.

According to data from commodity intelligence firm Kpler, the 'BW Brussels,' carrying Nigerian LNG, turned south in the direction of the Cape of Good Hope.

The intensified competition for LNG cargoes comes as Europe recovers from an unusually cold winter that significantly drained its natural gas reserves.

Simeone Tagliapietra, a senior fellow at the Bruegel think tank, noted, "Stocks have never been this low at this time of year. Refilling storage for next winter needs to start now. If replenishment must occur at current prices, it will place a substantial burden on Europe."

Data from Gas Infrastructure Europe shows that EU gas storage levels are currently below 30%, compared to a five-year average for the same period of approximately 45%.

Countries such as the Netherlands, Sweden, Croatia, and Latvia have particularly low reserve levels.

An EU official indicated that it remains possible to refill storage to 90% before next winter, adding that member states did not call for coordinated price-limiting measures during a meeting on Wednesday morning.

Dutch Prime Minister Mark Rutte said on Tuesday that the Netherlands is not at risk of running out of gas, though the government is preparing unspecified support measures. He emphasized, "The current priority is to replenish gas reserves as quickly as possible."

A senior energy trader mentioned that EU storage facilities typically see little withdrawal after late March, and given the current warm weather, "we have almost stopped withdrawing."

Since 2022, the EU has diversified its supplies, reducing dependence on Russian gas by increasing imports from the United States and securing more supply from Norway.

Only about 10% of Europe's LNG comes from Qatar. However, if competition for supplies from other sources continues to drive up prices, inflation could rise significantly and dampen economic growth, particularly in countries like Italy and Germany that rely more heavily on LNG imports.

Even before this week's price surge, eurozone inflation had risen to 1.9% in February, exceeding market expectations.

European Central Bank Chief Economist Philip Lane warned that a prolonged conflict in the Middle East could lead to a "significant spike in energy-driven inflation alongside a sharp decline in economic output." Nevertheless, current European gas prices, around €48.77 per megawatt-hour, remain far below the peak of €340 reached in 2022.

Some analysts have speculated that an extreme option to bolster European gas supplies would be to extend imports from Russia. The EU had planned to begin phasing out Russian LNG imports starting in April, beginning with short-term contracts and covering all contracts by the end of the year.

However, analysis firm Rystad stated that such a proposal would be highly politically contentious and face opposition from the United States, which has significantly increased its LNG exports to Europe since Russian supplies declined, making the scenario "highly unlikely."

On Wednesday, Russian President Vladimir Putin suggested that gas supplies to Europe could be cut off before the EU's ban takes effect, though he described the comment as merely "thinking aloud."

The ongoing conflict may push Europe closer to the United States. German Chancellor Friedrich Merz discussed trade relations with Donald Trump in Washington on Tuesday.

If the Middle East conflict persists, analysts expect governments to implement other measures to control prices, though many of these could conflict with Europe's climate goals.
