Europe Heads Into Winter With Gas Storage at Two Decade Low

Natural gas supply risks are mounting as Europe heads winter with storage about 63% full; its US listed fund proxy, UNG, was $10.87, up 0.09% on September 23.

Europe heads winter with storage near a two decade low

European gas storage stood at about 63% of capacity, the weakest level for this point in the year in nearly two decades and below the five year average, according to Gas Infrastructure Europe. The shortfall follows a cold 2025 to 2026 winter that drew down inventories, leaving policymakers and gas network operators needing a strong refill season.

The refill has fallen behind. Europe entered spring and summer needing to buy gas for storage while also meeting higher demand for electricity during heatwaves. But the war in Iran and the sharp reduction in Qatari liquefied natural gas supply upset those plans. Qatar’s LNG cargoes were caught behind the Strait of Hormuz, narrowing the supply available to buyers elsewhere.

Now the Netherlands has become the first European Union member state to warn that it will miss its storage target. That warning points to a tougher refill effort across the region, though low inventories do not mean supply is immediately at risk. The concern is what happens if storage remains depleted as heating demand rises.

Europe has relied on favorable winter conditions in recent years to ease pressure on gas supplies. The present storage position makes another mild winter helpful, but it does not remove the challenge of securing enough fuel before December. Analysts have also warned that the European Union could miss even its flexible goal of reaching 75% full by November 1.

Qatari supply losses intensify the contest for LNG

Europe is competing with Asian buyers for LNG cargoes that can reach customers without passing through the Strait of Hormuz. The contest has grown sharper because Asian importers are also seeking alternatives to contracted Qatari supply that did not arrive during the previous six months. Europe is losing that contest for readily available cargoes, complicating efforts to refill storage.

The disruption arrived during the seasonal window when Europe normally builds inventories for winter. With less LNG available internationally, buyers are pursuing a smaller pool of flexible shipments. The source material provides no production figures for Qatar or other suppliers, so it does not quantify lost output. It does describe a major reduction in available Qatari cargoes and the resulting squeeze on global supply.

Price signals have made the buying task harder. For much of the summer, European gas futures for near delivery traded above contracts for later dates. That pricing structure, together with elevated costs, discouraged stockpiling. Yet storage still needs filling before the heating season, leaving buyers to pursue supply even when conditions are unfavorable.

The geopolitical outlook remains central. Gas flows have been more affected than oil flows by the largely closed Strait of Hormuz, and the conflict’s course leaves uncertainty about when Qatari cargoes might resume. Without those shipments returning soon, Europe must rely more heavily on LNG sourced from elsewhere while facing Asian competition for the same supply.

European gas prices and the UNG market proxy

European benchmark prices at the Dutch Title Transfer Facility rose this month to their highest level since 2023. Liquefied natural gas prices in northwest Europe also reached a three year high. Those moves reflect the supply squeeze and uncertainty over whether Europe can secure enough fuel before winter, rather than a single change in demand.

The United States Natural Gas Fund, LP Unit, trades as UNG and offers a market proxy, not a direct quote for European gas or LNG. On September 23, the fund was at $10.87, up 0.09% on the day. Its 52 week range was $9.54 to $11.85. Those figures show the fund’s own trading level and should not be read as the price of gas at the European TTF hub.

The supplied market data does not include a dollar index reading or a direct measure of how currency moves affected natural gas. The small daily change in UNG therefore cannot establish whether the dollar supported or weighed on gas prices. The stronger evidence in the available material concerns inventories, LNG availability and competition among buyers.

Analysts have warned that missing the 75% storage goal could force European buyers to make purchases at higher prices, adding further upward risk. Prices are still far below the records reached in 2022, but Wood Mackenzie said in late July that Europe was nearing energy crisis territory. It also reported that spot prices had climbed 50% since mid June, when the now defunct US and Iran agreement effort was announced.

Lower consumption cushions, but does not erase, the risk

Europe uses about 10% to 15% less natural gas than it did in 2021. A larger renewable share in electricity generation has reduced gas use, while industries have adjusted to tighter markets and higher prices after years of abundant supply, including Russian gas. That demand reduction gives the region some protection compared with its earlier dependence.

It does not guarantee comfortable supplies this winter. Gas is needed both to refill storage and to meet energy demand, and the source material identifies summer heatwaves as a factor lifting electricity needs. If inventories remain low and LNG stays constrained, the cushion from lower consumption may not be enough to prevent a costly winter.

Households are already facing the effects of higher gas costs. The timing differs by country because energy markets pass wholesale prices through to consumers at different speeds. In the United Kingdom, the regulator has raised the household energy price cap by 4% for October through December, putting bills on course for a three year high at the start of winter.

Bill Farren Price, a distinguished research fellow at the Oxford Institute for Energy Studies, has warned that Europe could depend more heavily on just in time LNG this winter, while facing an even steeper storage refill task in summer 2027. That risk persists across different possible paths for the Iran conflict.
