Europe is confronting a significant energy crisis, with natural gas reserves plummeting to historically low levels, a situation the energy consultancy Wood Mackenzie attributes in part to the ongoing war in Iran.
Storage sites across the continent are currently just above 50% capacity, a considerably low figure for this time of year. This contrasts sharply with previous years when storage sites typically reached 90% capacity. Consequently, Europe is expected to enter the winter months with only approximately 75% of its storage capacity filled, a concerning deficit.
Massimo Di Odoardo, vice president of gas research at Wood Mackenzie, warned that the combination of low storage levels and intense competition for liquefied natural gas (LNG) will inevitably lead to elevated energy prices. "Low European inventories, strong Asian demand and limited new LNG supply growth almost guarantee elevated prices through this winter and into 2027," he stated.
LNG imports into Europe have notably slowed since the conflict in Iran began. Data from Kpler indicates that July imports are on track to total just 6.3 million metric tons, the lowest recorded since September 2024. A significant factor contributing to this decline is the resurgence of Asian demand for LNG, which has attracted a record four million tons of U.S. supply in June and July, diverting cargoes that might have otherwise gone to Europe.
Following a temporary opening of the Strait of Hormuz after a U.S.-Iran interim peace deal in April, there was hope that Qatar, a major global LNG supplier, would rapidly restore exports. However, renewed blockades of the strait amidst escalating tensions between the U.S. and Iran have extinguished these hopes. The European market is thus increasingly alarmed by the convergence of low inventories, weak imports, and a deteriorating supply outlook.
Benchmark European gas prices surged above €60 per megawatt hour last week, surpassing their previous peak during the Iran war and reaching their highest level since early 2023. While higher prices are expected to eventually draw additional LNG cargoes to Europe, even with potential import recovery, the region is likely to enter winter with gas inventories well below the targeted 80% storage level.
Bryn Jones, head of fixed income at Rathbones Asset Management, highlighted the critical nature of the situation. "Natural gas inventories are at record lows in Europe at a time they should be increasing to build stocks for the winter. Energy independence is becoming key for Europe," he noted.
The European Union has recently introduced an electrification action plan aiming to position Europe as the world's first "electro-powered" continent. The plan projects that doubling electrification to 46% by 2040 could result in annual savings exceeding €250 billion on fossil fuel imports. Compared to the 2021-2022 period, Europe is considered better positioned to handle gas supply disruptions. Dependence on Middle Eastern LNG is limited, with Qatar supplying only about 6% of imports, while the U.S. has become the primary supplier. With LNG constituting approximately 50% of EU gas imports, the region's supply base is significantly more diversified than during previous energy crises.
Samantha Dart, an analyst at Goldman Sachs, cautioned that Europe has "only small room for error" in its gas stockpiling efforts, with limited time remaining for storage injections before the heating season commences on November 1.
Diesel Market Under Strain
Europe is also facing considerable challenges in the diesel market, which has emerged as another critical area of energy stress. The continent relies heavily on diesel imports, and the fuel is vital for both transportation and industry, as well as serving as feedstock for heating oil. Typically, consumers and distributors build inventories during summer months to prepare for colder weather, but current inventories have been declining.
The war in Iran has disrupted key Middle Eastern supply routes and reduced diesel exports, forcing consumers to draw down existing stocks and pushing inventories to multi-year lows. European diesel inventories are at their lowest levels since 2022. Concurrently, U.S. stocks, the world's largest diesel exporter, fell to a 23-year low in May before recovering slightly by mid-July, according to the U.S. Energy Information Administration.
Policy decisions from major fuel exporters have further compounded the situation. China has restricted fuel exports since the Iran conflict began, aiming to conserve domestic supplies, with its future production and export plans remaining uncertain. Russia, previously the world's second-largest diesel exporter, imposed a ban on diesel exports in July following Ukrainian drone attacks that damaged refining facilities and reduced domestic fuel availability. Prior to this, Russia was exporting nearly one million barrels per day, representing about 12% of global diesel exports.
The ban has led to a dramatic increase in refining margins, with European diesel crack spreads recently reaching a record high of nearly $65 per barrel. These elevated prices are beginning to impact demand. The International Energy Agency reported that diesel demand in Europe dropped by over 6% in April. While some of this decline may be attributed to the ongoing shift towards gasoline-powered and electric vehicles, persistently high prices are also forcing consumers and businesses to reduce consumption.
Even if Middle Eastern tensions de-escalate quickly, the damage to global inventories is substantial. Both LNG and diesel markets are expected to remain undersupplied for months as nations work to rebuild stocks and compete for limited available supplies. This leaves Europe's energy security increasingly reliant on unpredictable factors, such as the weather. A mild winter could provide a buffer, but a prolonged cold spell increasing heating demand would expose the precarious state of Europe's energy system, potentially pushing the continent to the brink of a serious crisis after years of successive shocks.
