Key takeaway

A 20% Q1 global LNG supply cut meets a 6 bcm tightened EU injection target inside an unchanged regasification envelope.

The Oxford Institute for Energy Studies (OIES) published Quarterly Gas Review Issue 32 in April 2026, assessing the Q1 2026 global LNG supply cut at approximately 20% on the Iran war and Hormuz closure, and quantifying the EU additional injection requirement at 6 bcm more than Summer 2025 ¹.

OIES is the Oxford-based independent research body specialising in global energy markets; its Quarterly Gas Review is the reference document for trading desks sizing global LNG balances. A 20% Q1 supply cut is an exceptional loss by any historical comparison, and the institute's assessment is the closest thing the market has to an agreed figure for what the Hormuz closure did to first-quarter global supply.

The figure pairs with a corroborating primary estimate from the IEA April Oil Market Report. Two independent quantifications of the same order of magnitude give forward analysis a stable base to work from, and the OIES view narrows the uncertainty band on any mid-year resumption scenario. The closure of the pre-conflict Qatari supply bridge underlines how much of the 20% is now structural rather than transitional.

The 6 bcm shortfall versus last summer is the tighter ask inside a tighter global market. EU injection has matched rather than exceeded prior-year pace; the step-up required through May and June has not begun. Closing the gap depends on peripheral estates compensating for the German shortfall, constrained by the regasification envelope ENTSOG itself treats as fixed for the season. If Germany does not flip from net withdrawal before the 25 April ban , the OIES target moves out of reach inside the existing infrastructure. March's one-off surge in European LNG inflows was front-loading before the ban; the Q2 calendar does not contain another such window.

Deep Analysis

In plain English

The Oxford Institute for Energy Studies is a respected independent research body that studies global gas and energy markets. It recently published a report finding that the world's supply of liquefied natural gas (LNG gas cooled to liquid form for shipping) fell by about 20% in the first three months of 2026 compared to the same period last year. This happened because Qatar and the UAE, two of the world's biggest gas exporters, had their tanker routes blocked by the conflict closing the Strait of Hormuz. The report also found that Europe needs to find an extra 6 billion cubic metres of gas this summer on top of what it imported last summer just to reach a safe level for next winter.

Deep Analysis

Root Causes

The 20% Q1 supply cut is the direct consequence of Ras Laffan's role as the single largest LNG export complex in the world. QatarEnergy's force majeure declaration after the March strikes removed a 77 Mtpa complex roughly 17% of global LNG export capacity from the accessible supply chain in a single announcement. No individual complex in global LNG history had been so comprehensively removed from service while nominally intact.

The IEA mid-year resumption base case implies the disruption is reversible, but the 90-day minimum delay is a constraint on Qatari infrastructure assessment rather than diplomacy. Even under ceasefire conditions, Ras Laffan requires physical inspection, export pipeline integrity checks, and tanker scheduling reconstruction before loading can resume at full rates.

What could happen next?

Consequence
The IEA and OIES figures together constitute a cross-validated supply baseline that market participants will use to price Q3 and Q4 forwards, anchoring hedging costs for European utilities through mid-year.
Risk
If the Iranian transit count dispute is material and the true cut is 12-14% rather than 20%, the 6 bcm additional requirement shrinks but no public revision mechanism exists before the June quarterly update.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: The 1973 Arab oil embargo cut global oil supply by approximately 7% over four months, but the price effect was a 400% spike because the market had no visible adjustment mechanism and consuming governments had no Strategic Petroleum Reserves at meaningful scale. The 2026 LNG disruption is structurally different: LNG storage and regasification infrastructure provides a physical buffer the 1973 oil system lacked, and strategic gas reserves are now mandated across the EU.

Counter-parallel: The 2005 Hurricane Katrina disruption removed approximately 15% of US Gulf Coast LNG import capacity for three months a percentage broadly comparable to the 2026 Hormuz disruption in magnitude.

That episode resolved without a durable supply shift because Gulf Coast infrastructure rebuilt faster than projected. The 2026 scenario differs because the constraint is not physical infrastructure damage but a diplomatic-military standoff with a minimum 90-day resolution timeline even in the optimistic case.

Consensus view: The OIES 20% Q1 supply cut assessment is consistent with independently derived Kpler tracking data showing Qatari and UAE LNG loadings fell approximately 18-22% in Q1 2026 versus the same quarter in 2025, giving the figure a cross-validated base that makes it the market reference number rather than one analytical position among several.

Counter-view: Iran's Ministry of Petroleum publicly disputes the 20% figure, arguing that Iranian-approved transits via the CENTCOM carve-out mechanism sustained a higher actual throughput than Western analysts recorded, and that the effective supply cut is closer to 12-14% when Iranian-facilitated transits are counted. Iranian shipping analysts at the National Iranian Tanker Company (NITC) argue Western cargo-tracking data systematically undercounts AIS-dark vessels.

Key tension: Whether the OIES/Kpler 20% figure is the correct base for refill-season planning, or whether the true supply cut is smaller than assessed a question that materially affects the 6 bcm additional injection requirement and the pace needed to close it.

Different Perspectives

LNG spreads desk

The JKM-TTF arb flipped to a TTF premium of roughly USD 0.6/MMBtu on 15 July, the first time this cycle Europe has outbid Asia, yet no Atlantic cargo has rerouted west. Until a cargo actually moves, the desk reads the Hormuz premium as unconfirmed and the EUR 55 print as vulnerable to a fast reversal.

United States

Washington reimposed a blockade on Iranian ports and a 20% Strait of Hormuz cargo toll on 13 July, driving TTF's 9% two-session rally to EUR 54.995/MWh. The posture is again setting Europe's gas benchmark by sentiment rather than by any confirmed change in cargo flows.

EDF

EDF slipped the Bugey 3, Golfech 2 and Chooz 2 restarts to 19, 22 and 25 July, pushing all three past the 20 July Bugey heat exemption, after river-cooling limits on the Rhone, Garonne and Meuse forced the cuts. The same thermal ceiling has capped the fleet in every major heatwave since 2003, and this cycle is no exception.

German power desk

German day-ahead power climbed from EUR 126 to EUR 156/MWh over 14-16 July as the heat dome held, flipping the clean spark spread positive for the first time since 14 July. Gas-for-power demand is now back in competition with mandate storage injection right as the injection margin itself is thinning.

EU carbon and storage regulators

EUA carbon broke EUR 81/tonne on 13 July as the ETS Market Stability Reserve's scheduled withdrawals met fresh fuel-switching demand from France's nuclear curtailment. Brussels' mandatory storage-fill rule kept German and French injection running regardless of the TTF swings, the mechanism working as designed four years after the 2022 shock.

Equinor

Equinor returned its Asgard field from maintenance on 11 July, lifting Gassco's exit nominations to 319.8 mcm/day just as TTF round-tripped on Hormuz risk. The restart gave Norway spare pipeline capacity to help Europe absorb the gas rally without drawing down storage, reinforcing its role as the post-2022 swing supplier.
