NextFin News - Global gas demand is headed for its first annual decline since 2022 as the Iran war pushes prices higher, disrupts LNG flows and forces buyers to curb consumption, the International Energy Agency said in its latest quarterly gas market assessment. The warning matters because it shows a market that had been expecting a broad LNG supply wave is now contending with a major supply shock, a sharp jump in volatility and a demand response that is doing part of the balancing work.
The IEA said the effective closure of the Strait of Hormuz has removed almost 20% of global LNG supply from normal flow patterns and has driven prices in Asia and Europe to their highest levels since the 2022/23 energy crisis. In its Q2-2026 Gas Market Report, the agency said that every month without LNG cargoes transiting the strait implies around 10 bcm of LNG supply loss, a scale large enough to force industrial users, power generators and spot buyers to change behavior quickly.
The report said the conflict has already altered near-term gas fundamentals and medium-term investment expectations. Loadings from Qatar and the United Arab Emirates dropped by 9.5 bcm year on year, global LNG production fell by 8% or 4 bcm in March, and LNG deliveries were down by 2% or 1 bcm year on year in that month because shipping delays soften the immediate impact of a supply shock. Even after some easing in April, deliveries were still down by 10% year on year in the first 20 days of the month, underscoring how slowly the market can reroute volumes when a chokepoint is disrupted.
The demand response is the other side of the story. The agency said natural gas demand fell in key LNG-importing markets in March, with weather, higher prices and policy-driven fuel switching combining to reduce consumption. That is the critical reason the IEA is now talking about a possible annual decline: the war is not only cutting supply, it is also raising the clearing price enough to discourage use in price-sensitive markets. In Asia, where a number of countries are already stepping up demand-side measures and fuel switching, the adjustment is especially visible.
The broader backdrop helps explain why the shock is so disruptive. The IEA’s Global Energy Review showed that global gas demand grew by 2.8% in 2024, then slowed to 1% in 2025, or about 40 bcm, as weaker industrial activity and relatively high spot LNG prices weighed on consumption. Demand in Asia Pacific effectively flatlined in 2025, China’s gas demand rose only about 2% after a 7% increase in 2024, India’s use fell 3.5%, and U.S. consumption rose just over 1%. That already left the market less resilient than during the pre-crisis expansion phase; the Iran war has now landed on top of that softer demand profile.
That is why the IEA’s latest assessment reads less like a temporary price spike and more like a structural reset. The market entered 2026 expecting a stronger supply wave from new LNG projects in North America, Canada, Africa and elsewhere. Instead, the conflict in the Middle East has delayed the return of that surplus, reduced flows from key exporters and made buyers more cautious just as inventories and seasonal demand were still being balanced. The result is a tighter market not only for this quarter, but for the planning horizon that traders, utilities and industrial users actually price against.
What Changed In The Market
The central change is that the gas market is being forced to absorb a geopolitical supply shock at the same time as demand is becoming more elastic. In normal circumstances, higher prices mainly ration marginal consumption. Here, the shock is larger: the IEA says the closure of Hormuz has taken away almost 20% of global LNG supply from normal routing, while the March data show both production and deliveries falling in parallel. That combination means the market is not simply paying more for the same molecule; it is rearranging physical flows, ship schedules and end-user behavior all at once.
This matters because LNG is the most flexible part of the global gas system, but it is still constrained by liquefaction, shipping and receiving capacity. When Qatar and the UAE lose loadings, Europe and Asia do not instantly replace them. The IEA’s estimate that each month without LNG cargoes through Hormuz represents roughly 10 bcm of supply loss provides a scale for the interruption. A disruption that large can only be absorbed through some mix of higher prices, stock draw, alternative routing and lower demand.
Prices are the immediate transmission channel. The IEA said Asian and European prices reached their highest levels since the 2022/23 energy crisis. That comparison is important because it frames the current move not as a mild rebound, but as a return to the kind of stress that previously forced governments and companies into emergency procurement, conservation campaigns and fuel substitution. The market is once again being asked to respond to a crisis premium rather than a normal seasonal signal.
“The crisis has profoundly distorted short-term market fundamentals and is altering the medium-term outlook for natural gas.”
That assessment from the IEA captures why this story is bigger than one quarter of volatility. The agency is not describing a one-off price spike; it is saying the war has shifted the expected trajectory of supply growth and the timing of new LNG capacity. That is exactly the kind of change that can pull forward demand destruction in 2026 even if the market stabilizes later.
There is also a regional asymmetry that matters. Europe has already been managing a post-Russia supply reconfiguration, so any additional LNG disruption tends to hit spot pricing and storage strategy quickly. Asia, by contrast, is where much of the incremental long-term gas demand has been expected to come from. When the IEA says Asian countries are adopting demand-side and fuel-switching measures, it is describing a region that is no longer simply absorbing more gas as it grows. The war is making price a more active governor of demand than policymakers and traders had expected earlier in the year.
That is one reason the IEA’s demand warning is credible. A market that was already growing more slowly in 2025 is easier to tip into contraction when a supply shock raises prices fast enough to change behavior. This is not a model built on one country or one customer; it is a broad adjustment across importers, industrial users and power generators.
Why The Demand Outlook Turned Softer
The demand forecast is softening because the shock is hitting the market in three ways at once: it is making gas more expensive, it is making supply less reliable and it is encouraging substitution. Those are distinct channels, and the IEA is seeing evidence of all three. When prices jump to the highest levels since the last energy crisis, power systems and industrial buyers begin shifting toward cheaper alternatives where they can. When supply routes become uncertain, buyers become reluctant to overcommit. And when policymakers see energy security risks, they accelerate efficiency and fuel switching.
The demand pullback in March was therefore not just weather-driven. The IEA explicitly linked the decline in key LNG-importing markets to a combination of weather, higher prices and demand-side policy measures. That matters because it makes the demand response more durable than a one-off cold- or warm-weather move. A policy-induced switch away from gas can persist after prices normalize if governments continue to push efficiency, electrification and alternative fuels.
China remains central to the medium-term picture. Even before the Iran war, the IEA had already said China would account for almost half of global gas demand growth between 2022 and 2026 in the medium-term outlook. That makes Chinese buying behavior crucial to whether global gas demand merely slows or actually contracts in a given year. If China continues to grow more slowly than previously expected, the rest of the market has less room to absorb a shock from the Middle East.
Meanwhile, mature markets are not providing much offset. The earlier IEA medium-term outlook said demand from mature markets in Asia Pacific, Europe and North America had peaked in 2021 and was set to decline by 1% annually through 2026. The new crisis fits that framework: mature markets are structurally less able to provide incremental growth when prices spike. Instead, they are the first to cut usage, optimize fuel mix and squeeze efficiencies out of their systems.
That is why the current episode feels different from a normal supply scare. In a market with strong underlying demand, higher prices can be absorbed by growth. In a market where demand was already slowing from 2.8% in 2024 to 1% in 2025, a major supply disruption can more easily push consumption negative. The IEA is effectively saying the Iran war has arrived just as the gas market was losing momentum.
“After their heyday between 2011 and 2021, the world’s gas markets have entered a new and more uncertain period that is likely to be characterised by slower growth and higher volatility.”
That quote from Keisuke Sadamori is relevant because it frames the transition that now seems to be playing out in real time. Gas is no longer a one-way growth story. It is a volatile market where geopolitics, climate, policy and supply-chain constraints can change the demand path much faster than the industry can build new infrastructure.
What The Market Is Watching Next
The next test is whether the supply shock remains concentrated in the Middle East or broadens into a longer-lived global LNG shortage. If the Strait of Hormuz remains effectively closed for longer, the IEA’s estimate of roughly 10 bcm of LNG supply loss per month becomes the key number to watch, because it defines how long global buyers must keep rationing demand. If the disruption eases, the market can unwind some of the premium relatively quickly, but the damage to planning assumptions will linger.
Traders and utilities will also watch whether the delayed LNG supply wave eventually arrives on time from North America, Canada and Africa. The IEA said the conflict is expected to delay a significant amount of new LNG capacity that had been on track to come online in the second half of this decade. That is a bigger issue than near-term pricing because it affects the market’s margin of safety for 2026 and beyond. A delayed supply wave means any future shock will hit a tighter system.
For policymakers, the central issue is energy security. The IEA’s report underscores that Europe and Asia are again exposed to a supply chain that can be interrupted by geopolitics well before the market fully adapts. For industry, the issue is cost. Higher gas prices are already squeezing power generators, chemicals producers and other fuel-intensive users that cannot fully pass through the increase.
The analytical bottom line is that the Iran war is not just adding a risk premium to gas. It is accelerating the market’s shift from a period of expanding supply and slower demand growth into one defined by episodic shortages, more visible demand destruction and a more fragile balance between regions. If the current disruption persists, 2026 may be remembered not as the year LNG abundance arrived, but as the year the market discovered how quickly abundance can be deferred.
What looks like a temporary geopolitical shock is increasingly behaving like a demand-shaping event. The IEA’s message is that gas is now being priced, consumed and planned as a volatile security commodity, not as a steady growth fuel.
