How a Week of War Erased a Year of LNG Surplus: The Iran Conflict's Shock to Global Energy

In the span of seven days, the global liquefied natural gas market has undergone a transformation that analysts had considered a tail-risk scenario just weeks ago. A market that was widely expected to be awash in surplus supply through 2026 has flipped into what Morgan Stanley now calls a "rapidly emerging deficit" — with devastating consequences for energy-importing nations across Asia and Europe [1][2].

The catalyst was not a gradual tightening of supply fundamentals. It was war.

The Before Picture: A Market Bracing for Glut

Before February 28, 2026, the consensus view on global LNG markets was remarkably comfortable. New liquefaction projects coming online in the United States — including the Golden Pass and Plaquemines terminals — combined with expansions in Africa and the Middle East, were expected to push the global LNG market into an oversupply of roughly 6 million tonnes in 2026, according to Morgan Stanley's pre-conflict estimates [1][3]. The total market was sized at approximately 420 million tonnes per year.

Spot LNG prices in Asia had been trading in the low-to-mid teens per million British thermal units (MMBtu), while European benchmark Dutch TTF gas futures sat in the low €30s per megawatt-hour [4]. Analysts at Goldman Sachs, Wood Mackenzie, and the International Energy Agency were all broadly aligned: 2026 was supposed to be the year buyers regained leverage.

Then the United States and Israel launched joint military strikes on Iran on February 28, killing Supreme Leader Ali Khamenei and unleashing a cascade of retaliatory actions that would fundamentally reshape energy markets within days [5][6].

The Dominoes Fall: From Drone Strikes to Force Majeure

The retaliatory sequence was swift and devastating for energy infrastructure. On March 2, Iran's Islamic Revolutionary Guard Corps launched drone strikes targeting energy facilities in neighboring Qatar — a nation that, while not a belligerent in the conflict, found itself in the geographic crosshairs [7][8].

Two drones struck Qatar's energy infrastructure: one targeting a water tank at Mesaieed Industrial City and another hitting a facility at Ras Laffan Industrial City — the single largest LNG export complex on Earth [8][9]. QatarEnergy, the state energy firm, immediately halted production at both sites and subsequently declared force majeure on LNG shipments to all of its buyers worldwide [7][10].

The significance of this shutdown cannot be overstated. Ras Laffan alone accounts for roughly 20% of global LNG production. Approximately 80% of its output serves customers in Asia — primarily China, Japan, India, and South Korea [7][11]. In one stroke, the world's most important LNG facility went dark.

"This is the energy equivalent of shutting down the Suez Canal and the Panama Canal simultaneously," one London-based commodities trader told the Financial Times. QatarEnergy's CEO later told the same paper that the country would not be able to restart LNG production until "the conflict raging in the Middle East ends completely" [12].

The Strait of Hormuz: An Insurance-Driven Shutdown

The Qatar drone strikes were only half of the supply disruption. The other half came from the effective closure of the Strait of Hormuz, the narrow waterway through which roughly 20% of global daily oil supply and nearly all of Qatar's LNG exports transit [5][6].

Iran's IRGC issued explicit warnings prohibiting vessel passage through the strait. Attacks on commercial shipping followed. Within days, tanker traffic through the chokepoint dropped first by approximately 70%, with over 150 ships anchoring outside the strait to avoid the danger zone [5]. Soon after, traffic fell to effectively zero.

But it was not just military threats that sealed the strait. As CNBC reported, the shutdown became "insurance-driven" — marine insurers withdrew coverage for vessels transiting the waterway, and shipping companies refused to risk passage without it [6]. Maersk, MSC, Hapag-Lloyd, and CMA CGM all issued guidance to their fleets to avoid the area [5].

The result: a double disruption. Even if Qatar's physical LNG infrastructure could be repaired or restarted, the gas would have no way to reach buyers. The strait carries 19% of global LNG flows and 14% of refined petroleum products [5][6].

Markets in Shock: Prices Explode

The market reaction was immediate and severe. On March 2, benchmark Dutch and British wholesale gas prices surged by almost 50%, while Asian LNG spot prices jumped nearly 39% [7]. By March 4, Asian LNG spot prices had more than doubled to three-year highs, reaching $25.40 per MMBtu [1][3].

The European TTF benchmark climbed from the low €30s to over €60/MWh within days. By March 9, as the war entered its second week, TTF had pushed close to €70/MWh — roughly double its pre-conflict level [4][13]. Oil markets were equally shocked: Brent crude surged to $92.69 per barrel, while West Texas Intermediate spiked to $90.90, with WTI posting its largest weekly gain in futures trading history [5].

Morgan Stanley's commodities team, led by analyst Devin McDermott, issued a note on March 8 that crystallized the new reality: the pre-war surplus of 6 million tonnes had been effectively wiped out. "Any extension in the Qatar LNG outage beyond one month quickly brings a deficit," the analysts wrote [1][2]. If the shutdown persists, prices could breach $30/MMBtu [3].

Goldman Sachs followed with its own revised forecasts, raising second-quarter 2026 TTF and JKM (Japan-Korea Marker) price estimates substantially [14].

Asia at the Epicenter

The nations hit hardest sit in East Asia. Japan imports 95% of its crude oil from the Middle East and is among the world's largest LNG buyers. South Korea sources 70% of its oil and 20% of its LNG from the region [15]. Both countries activated emergency procurement protocols within 48 hours of the Qatar shutdown.

Japan's government immediately contacted American, Australian, and Canadian LNG producers about emergency spot cargoes [15]. But the arithmetic is sobering: Japan holds only two to four weeks of LNG reserves. South Korea's reserves range from nine to 52 days depending on whether government or independent estimates are used [15].

Analysts at the Atlantic Council warned that both nations could face "electricity and industrial rationing within four to eight weeks" if Gulf LNG supplies are not restored or replaced [11][15].

Pakistan and Bangladesh face an even more dire situation. As BusinessToday reported, both nations — heavily dependent on Qatari spot cargoes — are "staring at an energy abyss," with Pakistan's already fragile power grid facing potential collapse [16].

China, the world's largest LNG importer, is somewhat better positioned with more diversified supply chains that include pipeline gas from Central Asia and Russia. But it too relies heavily on Qatari LNG and is scrambling to secure alternative cargoes [11].

Europe's Uncomfortable Déjà Vu

For Europe, the crisis carries painful echoes of the 2022 energy shock that followed Russia's invasion of Ukraine. The continent is once again facing the prospect of competing with Asian buyers for scarce LNG molecules on the spot market [4][17].

The starting position is worse than many realize. EU gas storage entered 2026 at roughly 46 billion cubic metres at the end of February — compared to 60 bcm in 2025 and 77 bcm at the same point in 2024 [17]. Storage levels sit at around 30% full, well below the previous year.

Making matters worse, Russia's Deputy Prime Minister Alexander Novak announced that Russian LNG exporters would redirect some previously Europe-bound cargoes to Asia [17]. Moscow is reportedly considering redirecting all of its LNG exports to the Asia-Pacific region and signing long-term contracts with "friendly countries" [17]. Such a move would deprive the EU of another 12% of its LNG supply precisely when Qatari volumes have vanished from the market.

The Bruegel think tank in Brussels warned that Europe now faces a "gas storage scramble" — needing to fill storage ahead of next winter while competing against Asian buyers who are willing to pay premium prices [17][18].

America's Windfall — and Its Limits

The United States, now the world's largest LNG exporter, finds itself in an unusual position: geopolitically entangled in the conflict that is simultaneously generating windfall profits for its energy sector [19][20].

US LNG firms like Cheniere Energy and ExxonMobil stand to reap enormous gains as desperate international buyers bid top dollar for available American cargoes. Cheniere's stock price hit an all-time high of $255.15 on March 6, reflecting investor expectations of surging revenues [21].

But there are critical constraints. US LNG export terminals are already operating at near-full capacity, meaning there is little room to increase the volume of exports — only the price at which existing volumes are sold [19]. The infrastructure bottleneck means the US cannot single-handedly replace Qatar's missing 80-plus million tonnes of annual capacity.

Moreover, increased appetite for US LNG exports is likely to drive up domestic natural gas prices, creating political headaches at home even as energy companies celebrate overseas demand [19][20]. The Henry Hub natural gas spot price, the US benchmark, had already shown volatility in early 2026 before the conflict, and further upward pressure seems inevitable.

There is also an uncomfortable irony: the Trump administration's war on Iran — partially motivated by a desire to project American energy dominance — has created exactly the kind of global supply crisis that could fuel domestic inflation and consumer backlash [12][20].

The North Field Expansion: A Delayed Future

Perhaps the most consequential long-term impact of the conflict lies in what it does to future supply. Qatar's North Field East expansion — a massive $30-billion-plus project designed to add 32 million tonnes per year of LNG capacity — has been pushed back to at least 2027 [22][23].

The expansion was the single largest source of new LNG supply expected to enter global markets later this decade, forming the cornerstone of Qatar's plan to lift total production to 142 million tonnes per year by 2030 [22]. While the onshore processing plants were physically struck, offshore expansion activities — drilling and platform installation — have been paralyzed by the closure of the Strait of Hormuz [23].

Morgan Stanley has already removed approximately 1 million tonnes from its 2026 supply forecast due to the delay [1][2]. If the conflict extends for months, the knock-on effects on global LNG supply could persist well into the late 2020s, fundamentally altering the market's trajectory from the anticipated era of abundance to a prolonged period of scarcity.

What Comes Next

The outlook depends entirely on the duration and resolution of the conflict. If hostilities end within weeks and Qatar can restart operations at Ras Laffan within a month, the market disruption — while severe — may prove transient. Morgan Stanley notes that a one-month outage roughly erases the surplus; anything longer creates a deficit [1].

But the signals are not encouraging. QatarEnergy's CEO has indicated no restart is possible while fighting continues. The Strait of Hormuz remains effectively closed. And the North Field expansion delay ensures that even a rapid resolution would leave a lasting mark on global supply forecasts.

For energy-dependent nations in Asia, the crisis is accelerating a strategic rethink. Japan, South Korea, and others are expected to double down on energy diversification — investing in renewables, floating storage and regasification units, underground gas storage facilities, and pipeline interconnections to reduce their dependence on Gulf LNG [15].

For Europe, it is a grim reminder that the continent's energy security remains fragile, its dependence on volatile global LNG markets only partially addressed since the 2022 Russian supply shock [17][18].

And for the global LNG industry, the war has demonstrated with brutal clarity that the difference between surplus and shortage can be measured not in years of gradual market evolution, but in days of geopolitical upheaval. A market that was supposed to be comfortably oversupplied in 2026 is now, as Morgan Stanley's analysts put it, staring at a deficit — and the meter is still running [1][2].
