How the Iran Conflict Affects the Global Energy Markets

Going into 2026, the dominant story in global energy markets was not a war. It was a glut.

After a decade of construction, American LNG export terminals were finally hitting their stride. Golden Pass, Plaquemines Phase 2, Corpus Christi Stage 3 - roughly 36 million tonnes of new annual export capacity was set to come online this year alone.[1] The forecast was near-universal: too much supply chasing too slowly growing demand. Spot prices would soften. The Asia-Europe spread would compress. For import-dependent economies that had been paying crisis-level prices since 2022, relief was finally visible on the horizon.

That forecast is now gone.

In seven days, a single geopolitical event has restructured global energy markets in ways that will take years to fully price in. Understanding what actually happened - and what it reveals about the fragility of the system underneath - matters far beyond the immediate headlines.

What the Market Expected

The logic behind the glut forecast was straightforward. The United States had spent the better part of a decade building out LNG infrastructure on the back of its shale revolution, and the capacity was arriving all at once.[1] Meanwhile, renewable deployment was accelerating globally, eating into the incremental gas demand growth that LNG producers were counting on. Analysts at major banks were already warning that the industry's ambition to grow global LNG production by 50% by 2030 risked destroying its own price floor.[2]

For the energy transition, this mattered. Cheap LNG competes directly with wind, solar, and battery storage in the markets - primarily across Asia - where the fuel-switching decisions of the next decade will actually be made. When gas is cheap, coal-to-gas switching looks rational and coal-to-renewables looks expensive. The glut was a transition timeline story as much as a commodity one. And for the technologies designed to make intermittent renewables dispatchable - storage chief among them - cheap gas is the most formidable economic competitor they face.

Then came the last week of February.

Seven Days That Erased a Year of Forecasts

The US-Israel strikes on Iran triggered an immediate cascade of energy supply disruptions that, together, represent the most severe shock to global energy markets since Russia's invasion of Ukraine in 2022.

Qatar - the world's second-largest LNG exporter, responsible for roughly 20% of global LNG supply - suspended all production at its Ras Laffan and Mesaieed facilities following drone strikes on its infrastructure.[3] Simultaneously, the Strait of Hormuz, through which around 20 million barrels of oil per day and 20% of global LNG trade transits, experienced an effective commercial shutdown as insurers withdrew war-risk coverage and major shipping operators including Maersk, Hapag-Lloyd, and CMA CGM suspended operations.[4]

The price reaction was historic. US crude posted its largest weekly gain since futures trading began in 1983. Brent surged 28% - its biggest weekly move since April 2020.[5] European benchmark gas prices rose more than 60%.[6] Daily freight rates for LNG tankers jumped over 40% on the first day of the Qatar shutdown alone.[3]

On March 9, Morgan Stanley confirmed in a client note what the market was already sensing: the Qatar outage has erased most of the projected 2026 LNG surplus, and any extension of the production halt beyond one month "quickly brings a deficit."[7]

The glut is gone. The deficit is arriving instead.

The Structural Problem the Price Spike Is Hiding

Here is what the market pricing does not yet fully reflect.

The instinctive response to an LNG supply shock is to ask: who can fill the gap? In 2022, when Russian pipeline gas was cut off, the answer was US LNG - and American exporters ramped to meet European demand. That substitution logic is already being applied to the current crisis.

It won't work the same way. US LNG export facilities are running at 95–98% utilisation.[8] There is no meaningful spare capacity to deploy. The new terminals coming online in 2026 will add volume across the year, but they cannot be accelerated on demand. The cavalry is already riding at full speed.

This exposes something that import-dependent economies have been able to avoid confronting for years. Diversifying your fossil fuel suppliers is not the same as achieving energy security. When supply sources are geographically concentrated - and the Persian Gulf is the most concentrated energy geography on earth, routing roughly one-fifth of global oil and one-fifth of global LNG through a 21-mile waterway[4] - then spreading contracts across multiple suppliers provides far less protection than the paperwork implies.

Think of it this way: five power plants feeding your grid through a single transmission line. The line goes down, and all five plants become simultaneously irrelevant. That is the structure of Gulf LNG dependence. The 2022 crisis made this argument with Russian pipeline gas. The 2026 crisis makes it again, at larger scale, with seaborne LNG - except this time, the 2022 solution of switching to seaborne alternatives is itself the thing that's been cut off.

The technologies that break this logic share one characteristic: they don't move. A solar panel generates where it stands. A battery stores where it sits. Neither requires a chokepoint, a tanker, an insurer, or clearance through 21 miles of someone else's territorial waters. The energy security case for distributed generation and storage has always been argued in abstract terms - resilience, sovereignty, independence. This week produced the concrete price tag for the alternative.

What This Means for the Transition

There is a version of this crisis that extends fossil fuel dependency, and a version that accelerates the break from it. Which one materialises depends on decisions being made right now in the boardrooms and energy ministries of every major importing nation.

The dependency-extension path is the easier one in the short term: sign more long-term LNG contracts, build more regasification terminals, lock in supply chains that extend fossil fuel infrastructure by another twenty to thirty years. The shock provides political cover. The fear is real and the infrastructure gets built.

The other path has never had a clearer argument behind it. The energy strategist Kingsmill Bond said it plainly this week: "Asian policymakers will look at this and be less encouraged to go down the gas route."[9] Higher fossil fuel prices improve the economics of alternatives directly - making solar, wind, and storage more competitive without any policy support required. And critically, they create the fiscal and political urgency to move faster than any subsidy regime ever has.

Britain is a useful reference point for where that path leads. Over the past twelve months, combined wind and solar generation exceeded gas generation across all four seasons - the first time this milestone has been reached - with January 2026 setting a record of 10.87 TWh from wind and solar alone.[10] What makes that number meaningful is not just the generation - it's that the grid held. High penetration of variable renewables without adequate flexibility and storage behind it produces instability, not security. Britain's investment in both is what turns a wind record into a grid resilience story. The Hormuz closure moves UK gas prices. It does not threaten UK electricity supply. That distinction is the whole point.

The question energy ministers are now asking is not whether to reduce import dependence. It's how fast storage technology can make that reduction real.
