3% Drop in LNG Supply Threatens to Extend Global Market Tightness Into 2027
Key Facts
The International Energy Agency warned on November 3, 2026, that low European gas inventories could keep global gas markets tight beyond the start of 2027. EU storage sites are entering the 2026-2027 heating season with their lowest inventories since 2013, the agency said. The warning comes as liquefied natural gas supplies decline, leaving markets increasingly reliant on them to make up the shortfall. The agency said tightness could persist "deep into 2027." The outlook puts European winter supply in competition with global demand for available cargoes.
The agency expects global liquefied natural gas supply to fall 3% in 2026, or nearly 20 billion cubic meters. At the same time, it expects global gas demand to decline by about 1.5%, or roughly 65 billion cubic meters, during the same year. The agency attributes the demand decline to lower consumption in the Middle East and Europe, and to some energy consumers in Asia switching from gas to coal. Weaker demand partly offsets the impact of tighter supply, but does not remove the pressure to refill low European inventories. The balance between cargo availability and when they are needed therefore remains central to the market outlook.
The agency links the supply shock to the effective halt of LNG flows through the Strait of Hormuz, which cut loadings from Qatar and the UAE by more than 60 billion cubic meters between March and October 2026. The shock pushed gas prices in Asia and Europe to their highest levels since the 2022-2023 gas supply crisis. The impact of reduced flows is not limited to the lost volumes, as importing countries compete for cargoes that can be redirected flexibly between markets. The agency said declining Qatari and Emirati supplies came as Europe still needs gas to meet seasonal demand and rebuild inventories. This makes disruption to the maritime corridor a direct factor in global market tightness.
The agency warned that low European inventories, alongside limited storage options for LNG importers in Asia and South America, could intensify competition for flexible cargoes in the coming months. This could put upward pressure on spot prices, particularly at peak demand. The market is more sensitive because a flexible cargo may be sought in more than one region at the same time, while some countries cannot store large volumes in advance. The agency said these conditions "could intensify competition for a limited number of flexible LNG cargoes." The short-term price path may therefore depend on how winter demand coincides with Europe's need to replenish supplies.
European winter risks also depend on the weather and supply security. According to the agency, Europe could become more exposed to shortages if the coming winter is colder than expected, or if technical failures or other disruptions occur. In that case, withdrawals from storage could rise when starting inventory levels are historically low. This does not mean a specific shortage will occur, but it leaves less room to absorb demand surprises or supply disruptions. The agency said these seasonal risks come on top of the supply tightness linked to LNG flows.
The impact of low inventories extends beyond the heating season: the agency said they could increase the need for gas injections to refill storage during the summer of 2027. The refill process would keep European buyers in the cargo market after peak winter demand ends, potentially prolonging competition for global supplies. Against this backdrop, the agency on November 3 released its 2026 Global Gas Security Review and fourth-quarter Gas Market Report. It said growth in LNG supply, particularly from North America, and flexible trading arrangements are helping markets cope with the Hormuz shock. But it added that gas supply security risks remain acute.
