The Iran Conflict: Nuclear, Regional and Diplomatic

A 14-point US–Iran memorandum signed at Versailles on 17 June 2026 opened a 60-day ceasefire and briefly reopened the Strait of Hormuz, sending Brent crude down to around $78 a barrel, but that fragile de-escalation has since broken down. According to Het Laatste Nieuws and Le Soir, the United States launched fresh airstrikes on Iran overnight on 9 July, and Iran retaliated against US Gulf allies, with explosions reported in Bahrain, Kuwait and Qatar (Al Jazeera, Het Laatste Nieuws). President Trump warned the escalation could be "far worse," while the IMF cut its 2026 global-growth forecast citing the war (Al Jazeera). For Belgium, the fastest transmission channel is energy: renewed disruption at the Hormuz chokepoint has pushed Brent back toward $79 (Het Laatste Nieuws / ING), feeding eurozone inflation, ECB policy and pressure on Belgian households, hauliers and chemical producers.

Through June, the fighting repeatedly outran the diplomacy. US Central Command said its strikes were defensive responses to Iranian attacks on US forces and commercial shipping, and reported disabling the tanker M/T Jalveer after its crew failed to follow orders; India's shipping minister said a separate US strike killed three Indian sailors. Iran, for its part, declared Hormuz closed to unapproved vessels after renewed US strikes, and its Revolutionary Guard claimed it targeted the US Navy's Fifth Fleet in Bahrain, which released footage of what it said was intercepted Iranian drone debris.

Energy infrastructure became an explicit target of rhetoric. Trump said on 11 June that US forces could seize Kharg Island, which Euronews reported handles about 90% of Iran's crude exports. The EIA said very limited Hormuz traffic had already forced Middle East producers to cut output sharply and forecast Brent averaging about $105 a barrel in June and July, warning normal flows might not return before early 2027.

The June memorandum interrupted this pattern, but only briefly. According to Het Laatste Nieuws and Le Soir, the United States launched fresh airstrikes on Iran overnight on 9 July with deaths reported, and Iran retaliated against US Gulf allies, with explosions reported in Bahrain, Kuwait and Qatar (Al Jazeera). Trump warned the escalation could be "far worse" (Euronews, Le Soir), marking a clear return to open conflict.

The interim deal was built through intense, disputed mediation. Pakistan's PM Shehbaz Sharif said on 12 June that the US and Iran had agreed wording, while Iran's foreign ministry insisted Tehran had made no final decision; a senior US official put signing prospects at 80–85% but stressed the deal was not final. After several slipped deadlines and Qatari shuttle diplomacy to Tehran, US officials and PM Sharif said Trump and Iran's leadership signed the memorandum at Versailles on 17 June.

As described by the parties and corroborated across international reporting, the 14-point text opened a 60-day ceasefire and negotiating window, lifted the US naval blockade, issued temporary oil and banking sanctions waivers, and committed Iran to reopen Hormuz toll-free during the window, with talks on down-blending highly enriched uranium under IAEA supervision. Oil markets treated the signature as short-term relief: the AP cited Brent falling to $78.31.

But the deal was politically fragile from the outset. Iranian negotiator Mohammad Bagher Ghalibaf signalled Tehran still expected to charge shipping fees after the toll-free period, Republican senators including Ted Cruz attacked the concessions, and Israel — not a party to the memorandum — said it would not withdraw from zones it occupies. That fragility has now been borne out: the renewed strikes and Gulf retaliation reported on 9 July mean the ceasefire agreed in June has, in effect, broken.

Belgium is not a party to the war, and the corpus is consistent that its exposure runs through energy and prices rather than direct involvement. The chain is well documented: Hormuz disruption raises Brent crude, which feeds eurozone inflation and hence ECB policy, and lands on Belgian households, hauliers, airlines and energy-intensive chemical producers through fuel bills and supply contracts. The ECB said on 11 June that oil-price pressure from the Iran war contributed to euro-area inflation risks, and the article on Kharg Island noted the same producers and federal energy officials would feel any sustained oil or shipping shock.

The macro picture had already darkened before the July relapse. The World Bank cut its 2026 global-growth forecast to 2.5% — its weakest since the COVID-19 shock — with the AP reporting a eurozone forecast of just 0.8%, and on 9 July the IMF cut its 2026 global-growth forecast citing the Iran war (Al Jazeera). Brent's move back toward $79 (Het Laatste Nieuws / ING) reverses part of the June relief.

On supply resilience, the IEA says Belgium meets its oil-security obligations through APETRA-managed emergency stocks, and EU oil-stock rules require member states to hold emergency reserves for supply crises; the European Commission separately notes gas storage helps absorb supply shocks. These buffers are the practical backstop if Hormuz flows stay disrupted, though they cushion rather than cancel price transmission.

Whose ceasefire terms? Trump vs Iran — Trump said Iran's reported description of the draft did not match terms the US said were agreed in writing, and US officials framed the memorandum as performance-based, with sanctions relief and unfrozen assets tied to Iranian compliance. Iranian state-linked accounts, by contrast, presented fewer immediate concessions and emphasised early economic relief and recognition of sovereignty over the waterway — a genuine gap over what was actually signed.

Hormuz: toll-free passage vs future transit fees — US officials said the memorandum required Iran to restore commercial traffic through Hormuz toll-free for at least 60 days, with the US lifting its naval blockade. Iran's chief negotiator Mohammad Bagher Ghalibaf repeatedly signalled that Tehran still expects to assert control and charge ships for transit services after that window — leaving the central maritime term contested even as the deal was signed.

The "100 million barrels" claim: Trump vs his own Energy Secretary — Trump said a secret US military effort helped more than 200 commercial ships and 100 million barrels of oil transit Hormuz despite Iranian restrictions. US Energy Secretary Chris Wright told lawmakers he was not aware of millions of barrels being taken out as Trump described, and shipping-data estimates cited by analysts recorded far fewer confirmed transits — an unresolved dispute the corpus does not harden into fact.

What to watch next

The immediate question is whether the 9 July strikes harden into a sustained new phase of the war or prove containable. Trump warned the escalation could be "far worse" (Euronews, Le Soir), and Iran has shown it will strike US Gulf hosts — Bahrain, Kuwait and Qatar — which raises the risk to both shipping and the energy facilities concentrated around the strait.

On the deal, watch whether any element of the June memorandum survives, or whether the toll-free Hormuz arrangement and sanctions waivers lapse entirely. Two structural disputes were never settled and will shape any revival: Iran's claim, via Ghalibaf, to charge transit fees after the 60-day window, and the unresolved nuclear file, where the IAEA board's 10 June resolution demanded disclosure of the 440.9 kg of uranium enriched to 60% and access it says it has been denied.

For Belgium specifically, the markers are Brent's trajectory around and above $79, the next ECB signals on energy-driven inflation, and whether APETRA and EU emergency-stock mechanisms are invoked. The World Cup fixture against Iran has passed, but the energy relationship it symbolised — a distant war transmitted through a chokepoint into Belgian prices — remains the live story.
