The European gas market once again reminds Brussels of the difference between political decisions and economic incentives. Underground storage is not as full as regulators would like, traders are counting margins, and industry continues to pay for energy restructuring. The question is no longer only whether there will be enough gas for the winter, but how much guaranteeing its availability will cost.
Ninety percent on paper
European energy security increasingly resembles a complex equation where politicians define the desired outcome but do not control all the variables. According to estimates by Politico, at the beginning of October the filling level of EU underground gas storage was about 70% - one of the weakest indicators for this period in many years. For a continent that made stockpiling a central element of its strategy after the energy crisis of 2022, this is a troubling signal.
Particularly uncomfortable is the comparison to the 90% benchmark. However, there is an important legal detail here: after the review of European rules in 2025, the target storage filling level became more flexible, and the allowable period for achieving it was extended. Therefore, the 70% indicator alone does not prove a violation of current EU requirements. It indicates something else: the margin of safety before the winter season has turned out to be smaller than in previous years.
The difference between 70% and 90% is not an abstract twenty percentage points. With the total capacity of European storage exceeding 100 billion cubic meters, we are talking about significant additional volumes of gas. However, to automatically call them a physical supply deficit would be incorrect. Storage is just one of the sources of market supply alongside pipeline imports, LNG supplies, and current production.
When the market does not want to execute the plan
The paradox of European gas policy is that Brussels needs high reserves, while private traders do not always benefit from creating them. Usually, a company buys gas in the summer, injects it into storage, and sells it at a higher price in the winter. But this model only works when the difference between summer and winter prices covers storage, financing, and risks.
When summer gas becomes more expensive due to geopolitical upheavals, and the winter premium remains insufficient, the economics of injection deteriorates. Companies find it more profitable to sell fuel today than to hold it until the cold arrives. The regulator can set a target but cannot create profitability through a single decree.
Herein lies the contradiction between energy security and market logic. For the state, gas in storage is an insurance reserve. For the trader, it is an asset with storage costs and alternative capital costs. If society wants a larger reserve than the market is willing to finance, the difference must be paid for through special mechanisms, guarantees, or subsidies. There is no such thing as free energy security.
Industry pays first
For households, the main risk is not necessarily physical interruption of supply. The European gas infrastructure has become more diversified after 2022, and the capacities for receiving LNG have increased. The European Commission stated on October 8 that the system is capable of meeting winter demand even with lower storage levels. However, the sufficiency of gas does not mean its affordability.
According to estimates by the Institute for Energy Economics and Financial Analysis (IEEFA), as of October 3, European storage was only filled to 72.4%, and the potential need for consumption reduction in the winter could reach 14 billion cubic meters, or about 7% of last year's winter demand. This is a scenario estimate, not a fixed deficit. Instead of limiting consumption, Europe could attract additional imports, but analysts estimate the corresponding additional costs at around €3 billion.
The most sensitive to price pressure are energy-intensive industries: chemicals, metallurgy, fertilizers, glass, and other sectors where gas is not just fuel but a crucial component of the cost structure. They compete with producers in the US and Asia, where the structure of energy costs may be more favorable. However, stating that all of Europe's heavy industry has already reduced consumption by 20% or has massively relocated overseas would be excessive generalization. The real consequences vary depending on the country, enterprise, and industry.
Thus, European gas security has two different prices. The first is the cost of physically providing for the population and critical infrastructure. The second is the loss of competitiveness for enterprises that cannot pass on the more expensive energy to the buyer. And it is often the second price that remains beyond optimistic statements about successfully getting through the heating season.
American gas and the European price of independence
The abandonment of a significant portion of Russian energy resources has changed not only supply routes but also the nature of risk. Previously, Europe was overly dependent on one major pipeline supplier. Now, it is more dependent on the global LNG market, where cargoes compete for buyers, and prices respond to wars, logistics, and demand in other regions.
The impact of the conflict around Iran and supply disruptions through the Strait of Hormuz has been particularly significant. European prices have risen, and low storage levels have heightened vulnerability to a cold winter. At the same time, it cannot be argued that Asia always outbids European offers: LNG flows shift depending on regional price differences. In early October, Reuters reported that significant volumes of American LNG continue to flow to Europe.
The US has indeed gained new opportunities due to the rise in European demand for LNG. American exporters benefit from market expansion, while individual industrial investors benefit from relatively affordable energy within the country. However, to call the United States the sole beneficiary of Europe's problems would be to ignore the interests of other suppliers, transportation companies, and European enterprises that also operate in this market.
The main problem for Brussels is not that diversification was unnecessary. It has reduced strategic dependence on Russia. The problem is that geopolitical independence does not guarantee economic affordability. Europe has obtained more alternative routes, but at the same time, it has felt the global competition for energy resources more acutely.
In the winter of 2026-2027, the EU enters not with empty gas storage and not facing inevitable energy collapse. It enters with a smaller reserve, more expensive risk insurance, and a more complex choice between budgetary costs, industrial competitiveness, and energy security.
Gas in Europe is most likely going to be available. The question is, how much industry can afford at its price.
