Fifty kilometers wide. That is all that separates the Persian Gulf from the Gulf of Oman — and, by extension, Europe from an energy crisis it cannot negotiate its way out of.
The Strait of Hormuz handles roughly 20 million barrels of liquid fuels every day, about 19% of global supply, including nearly 14 million barrels of crude — a third of all seaborne oil trade. Qatar and the UAE ship virtually all of their liquefied natural gas through it. When Iran closed the strait on February 28, following the US-Israeli military campaign, Europe’s gas market went into a kind of suspended animation that has lasted nearly three months. It has not recovered. Nor has the diplomacy that might end it.
What the numbers look like from Brussels
The TTF — the Dutch Title Transfer Facility, Europe’s benchmark natural gas futures contract — is the most honest real-time measure of how nervous the continent’s energy traders are. Before the conflict, it sat at around €40 per megawatt-hour. As of May 25, it has edged back below €49/MWh, near a six-week high, a level that reflects neither panic nor relief — just deep uncertainty about what happens next.
Bank of America’s stress-test models put the plausible range for TTF at €40 to €150/MWh under current conditions, with an extreme scenario that could push past the all-time high of €240/MWh hit in August 2022 during the Russia crisis. The difference this time, analysts warn, is the speed of the shock. In 2022, Russian pipeline gas fell gradually, giving Europe months to scramble for alternatives from Norway, the United States, and elsewhere. This time, LNG from Qatar and the UAE stopped almost overnight. European storage levels are now hovering near the same dangerous lows they hit four years ago.
Bank of America calculates that every month of continued disruption drains roughly 10% of European gas storage capacity. If the outage stretches to ten weeks, TTF prices in the first quarter of 2027 could exceed the 2022 record. The math is not complicated; the politics that produced it are.
UNCTAD’s shipping tracker puts the human scale of the blockade in starker terms: vessel traffic through the Strait of Hormuz has fallen 95.3% since February 28. European crude prices are up 53%. Global food commodity prices have risen 6% — a figure that matters because the Middle East accounts for 40 to 50% of globally traded urea, the nitrogen fertilizer that underpins roughly half of the world’s food production. Almost all of it moves through Hormuz. Energy insecurity and food insecurity, it turns out, share the same chokepoint.
A timeline of the talks — and what they did to prices
For European energy traders, the US-Iran negotiation has functioned as an on-off switch. Here is how it has played out.
February 28 — The strait closes
Following US and Israeli strikes on Iran, Tehran announces the closure of the Strait of Hormuz. Daily ship transits fall from around 130 vessels to fewer than 10 — a drop of more than 90%. LNG exports from Qatar and the UAE come to a near-total halt. European energy markets lurch sharply higher.
Early March to mid-April — Markets reprice for a long blockade
With no diplomatic off-ramp in sight, traders begin building a structural risk premium into prices. Bloomberg NEF warns that oil markets are facing the worst supply shock since the 1990 Gulf War. European crude is up more than 50% from pre-conflict levels. Brussels begins internal discussions about tapping strategic reserves. A single LNG tanker from Abu Dhabi’s Das Island facility — the Mubaraz — sits anchored in the Gulf for weeks, unable to move.
April 19–21 — First talks, Islamabad
Washington sends a negotiating team to Pakistan, which has offered to mediate. Iran’s parliament security committee chair publicly says there are “no plans” for talks with the United States. Iranian advance teams arrive anyway. The signals are contradictory enough that markets barely move — TTF dips slightly on the headline, then reverses when Tehran walks back its participation.
April 28 — The Mubaraz moves
The stranded LNG tanker reappears in waters west of India — the first confirmed sign that an LNG vessel has transited the strait since the closure. It is a small data point, but markets take it as a signal that the blockade has soft edges. TTF pulls back briefly.
May 1–3 — Iran tables a proposal; Trump rejects it
Iran submits a 14-point negotiating framework through Pakistan. Its demands: full US military withdrawal from the region, the lifting of the naval blockade, war reparations, and a permanent ban on Israeli vessels using the strait. Trump calls the proposal unsatisfactory and says Iran “has not yet paid a high enough price,” threatening renewed airstrikes. New York crude futures fall more than 5% intraday — not because peace looks closer, but because an escalating conflict raises the prospect of deeper, longer disruption. The USS Gerald R. Ford carrier strike group leaves the Middle East the same day, leaving the Lincoln and the Bush.
May 5–8 — A one-page memo, 48 hours to respond
Trump calls the odds of a deal “very high,” then adds that reaching one is “perhaps a very large assumption.” The whiplash is characteristic. On May 6, US media report that Washington has delivered a one-page, 14-point memorandum of understanding to Tehran via Islamabad: Iran reopens the strait and caps its nuclear program; the US lifts some sanctions and unfreezes Iranian assets. Sources describe it as the closest the two sides have come to agreement since the conflict began. Iran is given 48 hours to respond.
On May 8, skirmishes break out near the strait again. Trump says the ceasefire is still in effect and that talks are going “very well.” TTF drops as traders price in a slightly higher probability of resolution.
May 18–19 — Sanctions relief, tentatively
A source close to both negotiating teams tells reporters that Washington has agreed in principle to a temporary sanctions waiver on Iranian oil exports — administered by the Treasury Department’s Office of Foreign Assets Control — to run during the negotiating period. Neither government confirms it. Oil prices rise. European gas edges lower. Vice President Vance says negotiations have made “significant progress” but confirms the US has a Plan B. Markets do not know what to do with that.
May 23–24 — The deal that wasn’t
On May 23, Trump posts that the two sides have “basically” reached a deal. Secretary of State Rubio, speaking in India, says good news could come “within hours.” Overnight crude futures drop sharply. The reported terms: a 60-day memorandum of understanding, the strait reopens and Iran clears its mines, the US lifts the port blockade and allows Iranian oil sales, and both sides begin negotiations on Tehran’s nuclear program.
Then Trump walks it back. The probability of a deal, he says, is “about fifty-fifty.” He tells his negotiating team not to rush because “time is on America’s side.” Iran’s military issues a statement that it is ready to respond to “any aggression.” A senior US official tells CNN the deal will not be signed on the 24th. Details are still being worked out.
May 25 to now — Waiting for June 5
The next round of formal talks is expected on June 5. Trump reaffirms that the blockade remains fully in force until a deal is signed and verified. TTF holds below €49/MWh — not high enough to suggest a new crisis, not low enough to suggest the old one is over.
Europe watches from the sidelines
The EU is among the largest energy importers in the world and has no seat at this table. Israel has complained about being shut out of the US-Iran talks; Europe was never in the conversation to begin with.
The costs are concrete. European crude is up more than 53% since February. Industrial electricity prices are running at levels that undercut the competitiveness goals of the EU’s Industrial Acceleration Act, the bloc’s flagship push to rebuild manufacturing capacity. Gas storage is near the 2022 danger zone, and unlike 2022, there is no slow-motion pipeline wind-down to manage — the supply cut was immediate.
The fertilizer exposure adds another layer of vulnerability. The Middle East supplies 40 to 50% of globally traded urea. The region’s output travels almost entirely through Hormuz. A sustained blockade does not just raise energy prices; it raises food prices with a lag of several months, running through agricultural input costs into supermarket shelves. European inflation, which the ECB has spent years bringing down, faces a new imported pressure that no interest rate decision can address.
What Brussels can actually do is limited: activate emergency reserve mechanisms, coordinate storage sharing among member states, and make representations to Washington through diplomatic channels. None of that changes what happens in Islamabad or Tehran.
The same trap, different pipeline
Europe’s current exposure is, in part, the consequence of its last crisis. After Russia’s full-scale invasion of Ukraine in 2022, the EU spent enormous political and financial capital weaning itself off Russian pipeline gas. It diversified toward US LNG, Qatari LNG, and Norwegian pipeline flows. That diversification was real and necessary. It also meant that when the Strait of Hormuz closed, a large share of the supply Europe had built its post-Russia strategy around went offline simultaneously.
The structural lesson is uncomfortable: Europe replaced dependence on a pipeline it could not control with dependence on a shipping lane it cannot protect. The geography changed; the vulnerability did not.
A report published this morning by Euronews flags a parallel problem in the digital economy — Europe risks falling into a similar “dependency trap” in artificial intelligence, with core compute, frontier models, and cloud infrastructure concentrated in a handful of US technology companies. The EU faces, in other words, the same strategic question in two different sectors: how do you build genuine autonomy when the global infrastructure you depend on is owned by someone else?
The price of politics
TTF, May 25: €48.7/MWh.
That number will move again when the next statement comes out of Washington or Tehran — up if talks collapse, down if a deal looks real, sideways if Trump says both things in the same press conference, which he has done before.
The June 5 talks are the next fixed point on the calendar. Whether they produce a 60-day memorandum, a breakdown, or another round of deliberate ambiguity from both sides is genuinely unknown. What is known is that European storage operators, utility executives, and finance ministers are watching Islamabad rather than Brussels for the answer to the most consequential question facing the EU’s economy this summer: will the gas be there when winter arrives?
