Monday through Friday, European gas traders watched the same negotiation cycle play out again. Washington said a deal was close. Tehran said the terms were being misrepresented. Trump posted something on Truth Social. Markets moved. Then Trump added a condition, or Iran pushed back on a clause, or the ceasefire was briefly violated somewhere near the strait, and prices moved back. By Friday, the TTF front-month contract was trading at €49.2 per megawatt-hour — almost exactly where it started the week, and roughly 35 to 40% above where it was on February 27, the day before everything changed.
The memorandum of understanding between the United States and Iran has not been signed. The Strait of Hormuz remains effectively closed. This is now the third consecutive week in which a deal has been described as imminent by at least one government, and in which no deal has materialised.
What the week actually produced
Monday opened with TTF above €49/MWh, extending the previous session’s gains after the weekend brought no diplomatic progress. Iran had fired several ballistic missiles toward Kuwait and Bahrain; American and allied forces intercepted them. The US struck an Iranian military ground control station on Qeshm Island in response. Vance, when asked whether the ceasefire was holding, said it was “a little messy” but “very much holding.” The ceasefire, now in its seventh week, has been punctuated by enough “defensive strikes” and “warning shots” that calling it a ceasefire requires some generosity with the definition.
By midweek, Al Jazeera’s analysis — published Thursday — summarised the state of play with unusual directness: both sides are closer to a deal than they were a month ago, but the Wall Street Journal had reported, citing unnamed US officials, that Trump told his aides he would consider ending the ceasefire entirely if any American troops were killed in Iranian strikes. That is not the posture of a government about to sign a framework agreement. It is the posture of a government keeping its options open, which is a different thing.
The Soufan Center’s June 1 assessment, still the clearest outside read of where things stand, had put the structural problem plainly: both sides are trying to present any eventual agreement as a victory, and the definitions of victory are incompatible. Iran wants its frozen assets unfrozen before it commits to nuclear restrictions. The US wants Iranian compliance verified before it releases anything. Neither of those positions has moved.
The clause that is holding everything up
The public version of the draft MOU — reported in sufficient detail by Axios, CNN, the Times of Israel, and PBS to be considered reliable — contains terms that both sides have separately described as agreed and as not agreed, depending on the day.
On the Hormuz reopening, the US position is that the strait must be “immediately open” to “unrestricted shipping traffic in both directions” the moment the MOU is signed, with no tolls. Iran’s position, as described by its state outlet Fars, is that it will open the strait “based on its predetermined arrangements,” which may include inspecting vessels, providing security services, and levying fees. Those two things are not compatible, and neither side has publicly moved.
On the nuclear question, Treasury Secretary Bessent told reporters there would be no sanctions relief until Iran agreed to turn over its highly enriched uranium. A senior Iranian source told Reuters that Tehran has not agreed to hand over its HEU stockpile and that the nuclear issue is not part of the preliminary agreement at all. Iran currently holds 440.9 kilograms of uranium enriched to 60% purity — a short technical step from weapons-grade. The IAEA has verified that figure. Whether it gets disclosed or diluted or transferred will not be settled in a 60-day memorandum. It is the argument that has defined US-Iran relations for twenty years.
What the MOU can do is create a 60-day window during which both sides negotiate those harder questions. What it cannot do is resolve them. The confusion — in markets, in press coverage, and apparently in the negotiations themselves — comes from treating the MOU as the agreement, rather than as a framework for reaching one.
What the storage data says about Europe’s exposure
While Washington and Tehran negotiate, European gas system operators are watching a different set of numbers.
Storage started the 2026 injection season at around 28% full, below last year’s 35% at the same point. The EU target is to reach 90% storage by November 1 — the threshold that, based on experience from 2021 and 2022, provides reasonable confidence of getting through a cold winter without extraordinary measures. Reaching 90% from 28% by November 1 requires a sustained injection rate above 3,566 GWh per day throughout the April-to-September window, according to EnergyRiskIQ’s modelling. That pace is materially higher than the rates achieved in recent years, in a summer where the LNG flows that would normally support injection are disrupted.
The ACER April assessment put the numbers in starker terms: TTF spot and forward prices have doubled their pre-conflict levels, and elevated forwards are sustained until at least mid-2027. If the Hormuz disruption persists from April to December 2026 with no additional piped gas, EU spot LNG requirements would rise to around 56 billion cubic metres — a demand figure that the market would struggle to supply at any price without significant demand destruction elsewhere. Winter 2025-26 was already colder than recent winters, particularly in Q1 2026, which drew down inventories faster than expected. The injection season that followed started from a weakened position.
The electricity market amplifies the problem. Gas accounts for 18 to 20% of EU electricity generation, but because of the bloc’s marginal pricing system, it disproportionately drives power costs across the grid. When TTF is elevated, day-ahead electricity prices in Italy and Germany run at €120 to €150 per MWh; France and Spain, with more diversified generation mixes, hold closer to €60 to €80 per MWh. The Hormuz disruption is not hitting Europe evenly, and the countries most exposed — Italy and Germany — are also the two countries most significantly behind on their 2030 climate targets, with the industrial competitiveness problems that implies.
The alternative supply routes, and their limits
There is a version of the energy analyst’s argument that says European gas markets are not as exposed as the TTF price implies, because alternative supply routes exist. It is worth engaging with that argument honestly, because it is partly right.
Norway has been a reliable swing supplier throughout the crisis. Norwegian pipeline exports account for roughly a third of EU gas supply and are not affected by Hormuz. US LNG cargoes, which route through the Atlantic rather than the Gulf, have been arriving in record numbers. Kpler forecast European LNG imports reaching 145 million tonnes in 2026, up significantly from prior years, and northwest European import terminals — including the FSRU facilities deployed in Germany, Belgium, and the Netherlands since 2022 — have capacity to absorb additional volumes.
The problem is quantity and timing. Even with increased US and Norwegian supply, the volumes lost from Qatar and the UAE — which shipped almost all their LNG through Hormuz — cannot be fully replaced in the summer injection window. Qatar is the world’s largest LNG exporter. The Ras Laffan complex, already damaged in the early weeks of the conflict, accounts for a significant share of global liquefaction capacity. Replacing Qatari volumes with US cargoes requires those cargoes to be available, to be price-competitive with Asian buyers also seeking alternatives, and to arrive in European terminals at the right pace to support injection. All three conditions are under pressure simultaneously.
ABN AMRO’s gas market monitor, published before the conflict, had projected TTF averaging €26/MWh in summer 2026, conditional on timely delivery of new US and Canadian LNG capacity. That projection assumed the Strait of Hormuz was open. It assumed the injection season started from a normal storage position. Neither condition holds. The gap between where prices were expected to be and where they are — around €49 versus the projected €26 — is the cost, in euros per megawatt-hour, of three months of failed negotiations.
Why Brussels is watching Islamabad, not Vienna
The EU has formal mechanisms for energy market emergencies. The Gas Coordination Group, chaired by the Commission, can facilitate emergency storage sharing between member states. The IEA can coordinate strategic reserve releases. The Commission can invoke Article 13 of the Gas Regulation to declare an emergency and mandate supply to protected customers. None of these tools affects the price. They affect distribution. They ensure that households get gas before industrial users in a shortage, and that member states with more storage share with those who have less. They are the managed-descent toolkit, not the prevention toolkit.
Prevention requires the strait to open. The strait opens if and when Washington and Tehran agree on terms that both can describe as a win. That negotiation is being mediated by Pakistan, with Qatar as a secondary channel. The EU is not in the room.
Kaja Kallas has said publicly that the Hormuz closure “hurts the global economy and helps Russia fund its war.” That framing — linking the Middle East crisis to the Ukraine conflict — is an attempt to put European interests on the geopolitical record in a way that obligates Washington to at least acknowledge the connection. It has not changed the pace of the talks, which is not Kallas’s fault. The EU’s leverage in this specific negotiation is close to zero.
What Brussels can do, and what several member state energy ministers are already doing, is accelerate the alternative supply conversations that will matter if the MOU is not signed before September. That means longer-term offtake agreements with US LNG suppliers, additional regasification capacity where permitting allows it, and renewed conversations with Norway about whether Equinor can sustain higher-than-planned production rates through the winter. None of those conversations have the immediate impact of a signed MOU. All of them will matter more than the MOU if the current negotiating pattern — agreement imminent, deal not finalised, ceasefire a little messy — extends into autumn.
The scenario no one is planning for publicly
European governments are not, in their public communications, planning for the scenario in which the MOU is not signed and the Hormuz disruption extends through the 2026–27 winter. They are planning for resolution, or at minimum for a partial opening that allows some LNG flows to resume. The political cost of planning publicly for the worst case — which would involve mandatory demand reduction, emergency industrial curtailments, and potentially very high household energy bills — is high enough that no government wants to front-run it.
The private planning is different. Energy security officials in Berlin, Paris, and Brussels have been running scenario analyses since March. The Bank of America stress-test range of €40 to €150/MWh for TTF under current conditions has not been superseded by anything more reassuring from the major analytical houses. ACER’s modelling shows sustained elevated prices through mid-2027 even on relatively optimistic assumptions about supply recovery. ING’s pre-conflict projection — that Europe would exit winter 2025–26 with storage around 25% full — turned out to be approximately right. The injection season that began from that level, into a disrupted LNG market, is the one that will determine whether the 2026–27 winter is manageable or not.
The MOU, if signed, would change that calculus significantly. A ceasefire extension with a committed Hormuz reopening and mine clearance within 30 days would allow Qatari and Emirati LNG to begin flowing again in July. European storage could plausibly reach 75 to 80% by November, below the 90% target but within the range of manageable. That is the optimistic scenario, and it requires the deal to be real and the mine clearance to happen on schedule.
If it does not, the numbers are considerably less comfortable.
Where this leaves the week’s verdict
TTF closed the week at €49.2/MWh. The MOU is unsigned. The ceasefire is holding in the loose, contested way that “holding” has come to mean in this conflict. The June 5 talks that were flagged as the next fixed point produced no announcement. The next fixed point is not yet publicly known.
For European energy markets, the week of June 1 to 6 was one more week of the same. Prices elevated, storage below target, LNG flows below what the injection season needs, and the negotiation that would change all of that still circling the same unresolved clauses — the Hormuz opening conditions, the frozen assets, the HEU stockpile — that have separated the two sides since the draft was first reported in late May.
The summer is not long.
