European gas buyers could face a second procurement challenge after winter, competing with Asian buyers for LNG cargoes to refill storage in 2027. Depleted inventories could keep summer prices and procurement costs elevated. The International Energy Agency (IEA) has warned that low storage buffers could prolong global gas tightness well into 2027.
In a scenario combining a cold winter with continued LNG disruption, European Union gas storage could fall to extremely low levels by the end of March. Even without that outcome, materially depleted inventories would require large injections in spring and summer, when Asian buyers are also securing cargoes for seasonal needs. Low stocks at end-March would keep procurement costs elevated after heating demand subsides.
The risk could build in two stages: prompt prices may rise during winter as stored gas runs low, followed by firm summer prices as storage operators seek large injection volumes. That refill premium could flatten or invert the normal relationship between winter and summer contracts. A weak winter-summer spread would reduce the commercial incentive for utilities and industrial buyers to inject gas.
Policymakers can set storage targets, but where the market does not provide a sufficient carry, the cost of building inventories would ultimately fall through regulated charges, government support, strategic procurement or higher retail tariffs. The refill challenge will coincide with the EU phase-out of Russian LNG from January 2027 and continued uncertainty around Qatari supply.
With those supplies in question, US LNG is expected to take a larger share of Europe’s marginal gas balancing. That would leave the market more exposed to the reliability of US liquefaction, Atlantic freight costs and the prices Asian buyers are willing to pay.
Summer 2027 contract prices, weekly storage withdrawals and LNG arrivals will indicate how much winter pressure carries into the injection season. The first quarter of 2027 is likely to retain a significant scarcity premium unless withdrawals are unusually light. If end-March stocks fall below roughly 20%, summer refill demand could support prices after heating demand fades; a level above 35% would materially reduce that risk.
