The US-Iran MoU: a ceasefire that destabilises more than it soothes

The memorandum of understanding signed on 17 June at the Palace of Versailles between Washington and Tehran, in force at once, stops the fire but settles nothing. It validates Iranian leverage over Hormuz, sidelines Israel and fractures a US political class now critical on both flanks. A sourced read of the geopolitical consequences and the US political risk.

On the announcement of the deal on 15 June, markets applauded: the S&P 500 closed up 1.6%, near its record, and oil fell nearly 5%, to its lowest since early March. That is perhaps the only simple thing in this memorandum.

On 17 June, Donald Trump signed with Iran a memorandum of understanding, a 14-point MoU, over a dinner with Emmanuel Macron at the Palace of Versailles, the day after the G7. The agreement took effect at once: the Strait of Hormuz reopens and the US naval blockade is lifted. It extends the ceasefire of the war launched on 28 February, when the United States and Israel had struck Iran and killed its supreme leader. The strait becomes free again, but for 60 days only, the blockade disappears within 30 days, Iran can export its oil from the signing, and sanctions relief remains conditional on Iranian compliance. Everything else, starting with the nuclear file, is deferred to a final agreement to be negotiated in 60 days. This is the direct sequel to the 2026 Iran war and the reopening of Hormuz.

What the MoU settles, and what it dodges

The market relief rests on one fact: the route that carries about 20% of world energy reopens. But most of the substantive issues are pushed back. The highly enriched uranium remains buried under the bombed sites, with no public Iranian commitment to surrender it. Trump told the New York Times that Iran would be allowed to enrich at a low level, reversing the total-dismantlement demand that had justified the war. The text also provides for a reconstruction plan of at least $300bn, backed by the United States and regional Gulf partners.

The 14-point MoU: settled now, deferred Settled now · Ceasefire (Lebanon included) · Hormuz reopened, free for 60 days · Naval blockade lifted within 30 days · Iranian oil exports authorised Deferred to a final deal · Nuclear and enriched uranium · Definitive lifting of sanctions · Withdrawal of US forces · Reconstruction fund ~$300bn 14 points read to the press on 17 June; MoU signed at Versailles, in force.

For the specialists, this is not peace. The Stimson Center and the Atlantic Council underline that the MoU resolves neither the nuclear file, nor the missiles, nor Iranian support for regional militias, that bilateral relations are not restored and that nothing substantial is secured. The most awkward reminder is that Trump claims to have ended a war he himself started.

The imbalance of concessions

The detail circulating, relayed notably by Washington Post journalist Aaron Blake and cross-checked by Axios and Fortune, shows a very asymmetric exchange. On the US side: ceasefire, lifting of the naval blockade, withdrawal of forces within 30 days, reconstruction funding, a commitment to lift “all types of sanctions”, waivers for oil exports, and asset unfreezing. On the Iranian side, two lines: return Hormuz traffic to its pre-war level, under Iranian arrangements, and “reiterate” that it will not seek the weapon. Concrete and irreversible on one side; on the other, the restoration of a strait that Tehran itself had closed, and the repetition of a promise it was already making.

A one-way exchange: who concedes what What Washington gives (7) · Ceasefire (Lebanon included) · Lifting of the naval blockade · Withdrawal of forces (after final deal) · Reconstruction funding (~$300bn) · End of "all types of sanctions" · Oil-export waivers · Asset unfreezing (tens of $bn) What Tehran gives back (2) · Hormuz traffic restored free 60 days, then fees · "Reiterates" not to seek the weapon nuclear status quo maintained Breakdown of the draft MoU (text not officially published).

On the money, caution with the big numbers. The reconstruction fund is announced at around $300bn, but Vice President Vance asserts it would be funded by a “Gulf coalition”, not by Washington, and conditioned on compliance with nuclear commitments. The asset unfreezing, for its part, is counted in tens of billions, not hundreds: the draft reported by the Mehr agency mentions $24bn over the 60 days of negotiation, a figure Washington calls “completely false”, drawn from a total stock estimated at around a hundred billion of which only a fraction is liquid, on the order of $30 to $50bn per the JCPOA precedent. The defensible order of magnitude is therefore a potential financial benefit north of $300bn, spread out and conditional, not an immediate transfer of 600.

Why it destabilises

The strategic problem is simple to state: the deal validates the leverage Iran seized by force. Reopening a strait that was free before the war, lifting its own blockade and unfreezing assets, is to reward the energy hostage-taking. The strait’s free passage lasts only 60 days anyway: the chief Iranian negotiator has already warned that Tehran will then collect fees on traffic, and called the MoU a failure for Washington. Tehran, whose leadership has become even more opaque after the death of its chiefs, believes it has won the standoff, and intelligence assessments cited by CNN indicate a resumption of drone production and military reconstruction, while the stock of more than 440 kg of enriched uranium remains beyond any control, deferred to the final agreement.

Second shockwave: Israel was kept out of the negotiations, conducted via Qatar. Netanyahu was caught off guard, and Trump criticised him publicly after an Israeli strike on Beirut, while Israel-Hezbollah fighting continues in Lebanon, whose inclusion in the ceasefire is itself contested. A major ally sidelined and displeased is the risk of a unilateral action that would blow up the 60 days. Finally, tolerating Iranian enrichment creates a proliferation precedent that worries the Gulf capitals.

The political crisis brewing in Washington

This is perhaps where the deal is most explosive. It fractures Trump’s own camp. Republican hawks, Ted Cruz, Lindsey Graham, Roger Wicker, Thom Tillis, and former adviser John Bolton, judge the agreement weaker than the 2015 JCPOA, the very one Trump had denounced. A White House confidant speaks of a “low-rent humiliation”. Facing them, the wing hostile to endless wars and candidates worried about gasoline prices ahead of the midterms mostly want out.

A Republican camp fractured over the deal Hawks: against "humiliation", "worse than the JCPOA" Cruz, Graham, Wicker, Tillis, Bolton Trump: triumph "historic peace", claims the win ends a war he started Anti-war: relieved exit the conflict, lower gasoline Moreno, and opinion mostly against the war Democrats attack from both sides; Congress was kept out of the text before its release. Sources: The Hill, NBC News, CNN, PBS, Foreign Policy (May-June 2026).

Three fault lines make the situation politically unstable. The narrative first: Trump launched the war to dismantle the Iranian nuclear programme, and he exits by authorising it at a low level, which frontally contradicts Pete Hegseth and the casus belli. The cost next: an unpopular war, at least $29bn and 13 US service members killed, to reopen a route that was already open. The method finally: Congress discovered the text as it was already circulating abroad, and the Senate advanced a war-powers measure. With a falling approval rating and midterms approaching, Trump is in a classic bind: a majority of Americans reject the war, but the price of exiting it, money and enrichment for Tehran, is precisely what his own hawkish base will not forgive. The criticism has moreover spilled beyond his camp: Senate Democratic leader Chuck Schumer judges that Iran won on nearly every one of the 14 points and that the country is worse off than before the war. Trump, for his part, added that he found it acceptable for Iran to keep some ballistic missiles, and warned that absent a final agreement within 60 days, they would go back to bombing.

The strategic balance sheet

This memorandum stops the fire, and that is real. But it settles none of the causes of the conflict, it enshrines Iran’s strategic gain, it cracks the axis with Israel, and it opens trench warfare in a US political class critical on both flanks, six months from the midterms. The destabilisation is therefore not a paradox: a ceasefire that distributes rewards without closing anything leaves all the tensions active, simply displaced from the battlefield to the negotiating table and Congress. Now signed and in force, the agreement opens a 60-day countdown: the delegations’ meeting on Friday in Switzerland is to launch the nuclear talks, but a unilateral Israeli strike, the reinstatement of Hormuz fees or a deadlock on uranium would be enough to reignite everything. Oil fell 5%. The risk, for its part, only changed address.
