Europe's natural gas market is facing its most severe supply shock since 2022, fueled by escalating Middle East conflicts. A combination of factors—including production halts in Qatar, shipping disruptions in the Strait of Hormuz, and threats from Russia to cut off supplies—has pushed the continent's gas storage levels to their lowest seasonal point in years, casting a shadow of a renewed energy crisis.

Since military actions against Iran began, the European benchmark gas price, TTF, has surged by 67%, briefly exceeding €54 per megawatt-hour, its highest level since 2023.

QatarEnergy recently announced a suspension of LNG production following attacks on its facilities, while shipping through the Strait of Hormuz—a vital passage handling roughly one-fifth of global LNG trade—has effectively stalled. In a notable shift, a vessel originally bound for France abruptly diverted toward Asia this week, marking the first Atlantic route diversion amid tightening supply.

Further unsettling the market, Russian President Vladimir Putin suggested on March 4 that, since the EU plans to eventually ban Russian gas imports, Russia might proactively cut off supplies and pivot to emerging markets. European gas storage currently stands at just 30% capacity, 15 percentage points below the five-year average for this time of year. The critical refill period, normally used to rebuild reserves, is now under strain from both shrinking supply and soaring prices.

Rising energy costs threaten to rekindle inflation. Eurozone consumer prices unexpectedly accelerated to 1.9% year-on-year in February, exceeding expectations even before the latest energy price surge. European Central Bank Chief Economist Philip Lane warned that prolonged conflict in the Middle East could trigger a "significant energy-driven inflation spike and a sharp output decline." European stock markets fell over 3% on Tuesday, while government borrowing costs in the UK, Italy, and Greece also jumped.

The immediate trigger for the crisis was retaliatory strikes by Iran on Qatari energy infrastructure. QatarEnergy, a state-owned firm, suspended LNG output after two facilities were attacked. As the world’s second-largest LNG supplier, the shutdown of its Ras Laffan export hub sent shockwaves through global gas markets.

Although EU imports from Qatar account for only 8–10% of its total supply, the interconnected nature of global LNG markets means that disruptions can have ripple effects far beyond direct trade shares. According to an analyst at Global Energy Monitor, the halt will "have a material knock-on effect on global LNG markets until production resumes, and it's unclear when that will be."

Meanwhile, the Strait of Hormuz—often called the "chokepoint" of global energy trade—has seen shipping effectively halted, cutting off a major artery for Middle Eastern energy exports. Heightened geopolitical tensions have amplified concerns over long-term supply disruption.

Morgan Stanley warned in a recent report that current TTF prices reflect only one to two weeks of supply disruption. In an extreme scenario where Qatar’s halt lasts for months, prices could surge toward €100, approaching 2022’s squeeze levels. However, the bank noted that Europe’s current fundamentals are stronger than in 2022, suggesting a less severe supply-demand imbalance.

Asian buyers, heavily reliant on Qatari LNG, are now competing with Europe for alternative supplies. Signals of a bidding war have emerged. A vessel carrying Nigerian LNG originally destined for France rerouted toward Asia via the Cape of Good Hope, marking an escalation in intercontinental competition for gas.

An analyst at Argus Media noted that Europe "will need to outbid Asia to replenish storage adequately before next winter." LNG shipping charter rates have climbed as European and Asian gas prices soar. In contrast, the United States, with ample shale gas output, has maintained stable domestic prices and remains a key exporter.

Amid an already tense market, Putin’s comments introduced further uncertainty. He suggested that Russia could preemptively cut gas supplies to Europe, given the EU’s planned import ban. Although characterized by some as offhand, the remarks carry psychological weight at a sensitive time.

Analysts suggest that if Russia acts before the formal ban takes effect, Europe’s refill challenge would intensify. The EU has legislated a full ban on Russian LNG and pipeline gas, with the former taking effect in early 2027. While resuming Russian LNG imports remains a theoretical option, it is considered politically explosive and unlikely.

Europe’s low gas storage exacerbates the crisis. EU-wide reserves are below 30% of capacity, well under the seasonal average. Germany’s storage is at just 21%, a record low for this period. Several other member states also face thin reserves. Italy is particularly exposed, with over one-third of its LNG imports coming from Qatar.

A senior fellow at Bruegel think tank noted, "Storage has never been this low at this time of year. Refilling for next winter must start now, and doing so at these prices would be a heavy burden." The European Commission has called an emergency meeting to assess national storage levels, with discussions likely on reinstating mandatory storage targets eased last year.

According to Capital Economics, if prices remain at current levels, eurozone inflation could rise by 0.5 percentage points. Earlier warnings from the ECB already highlighted risks of energy-driven inflation and falling output.

Some officials struck a more optimistic tone, suggesting that refilling storage to 90% by next winter remains feasible. A senior energy trader noted that net withdrawals typically stop after late March, and with warmer weather, "we have basically stopped drawing gas."

Despite echoes of 2022, key differences remain. Then, Europe had to hastily build alternative supply chains from scratch. Today, the EU sources nearly 58% of its LNG from the U.S., reducing dependence on Russia from 45% in 2021 to 13% last year. Supply availability is stronger, though high prices pose a distinct challenge.

A director at the Centre for European Reform noted that "this crisis is about price, not immediate physical shortage." Still, elevated energy costs could squeeze European industry, where power prices are already double those in the U.S. and 1.5 times those in China. Industrial firms like Siemens Energy and BASF have seen sharp stock declines this week. If gas prices persist, inflation pressures may lead markets to bet on the ECB maintaining higher interest rates for longer.
