United States and Iran sign Versailles memorandum to reopen Hormuz
The United States and Iran have signed a preliminary memorandum intended to end a 110-day conflict and restore commercial traffic through the Strait of Hormuz, according to U.S. officials and statements by President Donald Trump, French President Emmanuel Macron and Pakistani Prime Minister Shehbaz Sharif. The document gives Washington and Tehran 60 days to negotiate a final settlement, links wider sanctions relief to nuclear talks, and requires Iran to restore safe passage through the Strait of Hormuz, with a 60-day toll-free period. U.S. officials say the text also covers Lebanon and Iran’s regional allies, although Israel is not a party to the memorandum. The immediate consequence is energy-market relief, but the agreement is politically fragile: Iran says it may charge shipping fees later, European leaders want follow-up talks on missiles and regional activity, and critics argue the deal front-loads economic gains for Tehran.
Trump's America: From the First Term to Now
A living dossier on Donald Trump's political project, from the 2016 victory through the post-2020 contested period to his return to the White House in January 2025 — and the political, legal, economic and institutional consequences still unfolding.
For Belgian residents, commuters, SMEs, hauliers, farmers and energy-intensive firms, the direct channel is prices: the deal could ease fuel, gas and fertiliser pressure if shipping resumes. For EU officials and Belgium’s federal energy and foreign-policy teams, the test is whether a U.S.-Iran bargain stabilises a chokepoint that affects European inflation and security without sidelining EU leverage on Iran’s nuclear programme, ballistic missiles and regional armed groups.

The G7 (Canada, France, Germany, Italy, Japan, the UK, the U.S. and the EU) has backed implementation while seeking broader constraints on Iran.
Background
The ’s 2012 analysis described as the world’s most important oil transit chokepoint and said 2011 flows were almost 17 million barrels per day, about 35% of seaborne traded oil. The waterway has repeatedly been a flashpoint: U.S. forces escorted tankers during the 1987-1988 , U.S. naval forces shot down over the in 1988, and has periodically threatened closure during nuclear and sanctions crises. The 2015 nuclear agreement offered sanctions relief for nuclear limits, but the withdrew in 2018, weakening the framework that European governments had tried to preserve.
The wider picture
The memorandum tests whether energy security can force a diplomatic reset after military escalation. It also shows a shift from multilateral diplomacy toward a narrower U.S.-Iran transaction, with Europe seeking influence from the outside. China, states, and all sit in the background because , oil exports and are linked in the deal’s consequences.
Why now
The immediate trigger is the signing and public circulation of the memorandum during G7 diplomacy, after months of conflict and pressure to reopen . Markets and governments now need to know whether the document is an enforceable pause or only the start of another bargaining round.
What to watch
Watch the Switzerland meeting, any publication of the memorandum text, shipping volumes through Hormuz, U.S. Treasury waiver details, IAEA access arrangements, Iran’s position on post-60-day fees, and Israeli or Hezbollah actions that could test the Lebanon clause.
What happens next
U.S. and Iranian delegations are expected to use the 60-day window to negotiate a final settlement, including nuclear terms and sanctions sequencing. A planned Switzerland meeting could clarify who signs what, how Hormuz security is verified, and whether any final arrangement seeks UN Security Council endorsement. Israel’s response and Hezbollah-related implementation remain key uncertainties.
Potential consequences
If the memorandum holds, lower crude and gas prices could reduce pressure on European inflation and Belgian transport costs before winter storage season. If it collapses, markets could quickly reprice the risk of renewed blockade, tanker insurance costs and regional strikes. Diplomatically, a U.S.-Iran bilateral framework could also leave the EU with less direct leverage unless European governments secure a role in follow-up talks.
Impact
Local — The most concrete Belgian local effect is likely at petrol stations, logistics depots and ports such as Antwerp-Bruges, where fuel costs, shipping schedules and insurance assumptions feed quickly into margins. No Belgian authority has announced a region-specific measure tied to this memorandum, so the impact is economic rather than municipal.
International — The deal is primarily a U.S.-Iran bargain, but Europe is directly exposed through energy prices, Gulf shipping security and the future of Iran nuclear diplomacy. France’s role at Versailles and G7 support give European governments visibility, yet the negotiating channel appears dominated by Washington, Tehran and mediators such as Pakistan.
What it means for you
Belgian readers should not expect instant normalisation at the pump or on energy bills. The practical signal is direction rather than certainty: if tankers resume and insurers return, price pressure should ease; if implementation stalls, businesses and households should expect renewed volatility in fuel, gas and freight-linked costs.
Opposing perspectives
- Trump administration / U.S. officials
U.S. officials frame the memorandum as a practical off-ramp: reopen Hormuz, stop the shooting, and use the 60-day window to turn a battlefield stalemate into nuclear negotiations. In that reading, immediate oil waivers are not a surrender of leverage but the price of preventing a wider economic shock.
- Iranian negotiators / Tehran
Mohammad Bagher Ghalibaf’s public line presents the document as proof that U.S. pressure failed. Tehran’s strongest argument is that Iran kept enrichment and sovereignty questions on the table, avoided shipping its uranium abroad at this stage, and forced Washington to discuss sanctions relief and Hormuz access rather than dictating surrender terms.
- European G7 governments
European G7 governments welcome the reopening of Hormuz because it relieves energy and inflation pressure, but their strongest concern is that the memorandum leaves missiles and regional armed groups unresolved. Their frame is implementation first, then a broader follow-on agreement covering Iran’s nuclear, ballistic and regional activity.
- Israel and U.S. hardliners
Israeli leaders and U.S. hardliners see the bargain as too permissive because Iran receives early economic benefits while retaining bargaining room on enrichment, missiles and regional allies. Their strongest argument is that the deal may stabilise markets while weakening deterrence if verification and enforcement are not clarified quickly.
