United States and Iran sign framework to reopen Strait of Hormuz
The United States and Iran have signed an interim framework intended to halt the Iran war, reopen the Strait of Hormuz and start a new nuclear negotiation period. Pakistan's Prime Minister Shehbaz Sharif said the agreement took effect immediately and that Iran would reopen the strait while the United States lifted its naval blockade. U.S. officials said the memorandum gives negotiators 60 days to pursue a final deal, includes steps on Iran's highly enriched uranium, and waives rather than permanently removes some sanctions. Markets treated the signature as a short-term supply relief: market data cited by the Associated Press showed Brent crude falling to $78.31 early Thursday, below recent crisis peaks but still above pre-war levels. The strategic question is whether maritime traffic, insurance and nuclear diplomacy can normalise faster than political opposition in Washington, Tehran and the wider region can unravel the deal.
For Belgian households, drivers, hauliers, farmers, airlines and energy-intensive SMEs, the immediate issue is not diplomacy in the abstract but the price chain that runs from crude oil and shipping insurance into diesel, petrol, air fares, fertiliser and consumer prices. The International Energy Agency's March report said the Hormuz disruption hit crude, refined products and LPG flows, so a credible reopening could ease pressure felt across Belgium's transport and food sectors. EU policymakers in Brussels also have a direct stake because sanctions, nuclear monitoring and Gulf maritime security remain European security files.
The Strait of Hormuz (narrow waterway between Iran and Oman) is the key Gulf shipping route for oil, refined products and liquefied natural gas. Shehbaz Sharif (Pakistan's prime minister since 2024) presented Pakistan as a mediator in the U.S.-Iran framework. Masoud Pezeshkian (Iran's president since 2024) is the Iranian signatory named in U.S. accounts of the deal. Donald Trump (U.S. president, returned to office in 2025) signed the memorandum during the G7 summit period in France. The International Energy Agency (Paris-based intergovernmental energy body founded in 1974) tracks oil markets and emergency reserves. The International Atomic Energy Agency (UN-linked nuclear watchdog created in 1957) is relevant because the framework points to uranium dilution and future verification. Hezbollah (Iran-backed Lebanese armed movement and political party) matters because the memorandum touches Lebanon. The G7 (Canada, France, Germany, Italy, Japan, the United Kingdom, the United States and the EU) frames the allied response.
Background
The Strait of Hormuz has been a recurring flashpoint since the Iran-Iraq tanker war of the 1980s, when attacks on Gulf shipping drew U.S. naval escorts. In 1988, U.S. forces fought Iran in Operation Praying Mantis after a U.S. frigate hit a mine. The 2015 Joint Comprehensive Plan of Action temporarily constrained Iran's nuclear programme before the United States withdrew in 2018. In 2019, tanker attacks and ship seizures again raised fears of a Hormuz crisis. The International Energy Agency's March 2026 report said the latest conflict created the largest supply disruption in global oil-market history.
The wider picture
The deal tests whether energy chokepoints can be stabilised through a transactional ceasefire while deeper strategic disputes remain unresolved. Iran gains relief from immediate blockade and sanctions pressure; Washington gains a path to reopen shipping and restart nuclear talks. Gulf states, Europe and Asian importers gain breathing room, but only if Hormuz is treated as reliably open by shipowners and insurers.
Why now
The story is timely because Pakistan's prime minister said on 17 June 2026 that the signed memorandum had immediate effect, and markets reacted on 18 June with lower oil prices and higher Asian equities. The trigger is the signature, not merely another round of talks.
What to watch
Watch whether the planned Switzerland contacts proceed, whether Iran and the United States publish or clarify the memorandum text, whether tanker traffic and insurance rates normalise, and whether IAEA-linked uranium steps are specified inside the 60-day negotiating period described by U.S. officials.
Opposing perspectives
- Energy-market analysts
AP quotes Rice University's Baker Institute energy researcher Jim Krane as arguing that reopening Hormuz helps a tight market immediately, because oil stocks are low and any extra Iranian or Gulf supply relieves pressure. This view treats the framework first as an energy-security stabiliser, while warning that a later oversupply cycle is possible if production elsewhere has already ramped up.
- U.S. Republican Iran hawks
AP quotes Senators Bill Cassidy and Ted Cruz as arguing that the framework rewards coercion by easing sanctions while leaving Iran with future leverage over Hormuz tolls and unresolved nuclear questions. Their strongest case is that short-term price relief may come at the cost of normalising Iranian control over a global maritime chokepoint.
- G7-aligned de-escalation camp
Axios reports that Emmanuel Macron said the signature could reopen Hormuz and support lasting peace. This camp's strongest argument is that a flawed interim framework is preferable to an open-ended war that keeps energy markets, Lebanon, Gulf shipping and nuclear diplomacy in crisis at the same time.
