The US-Iran ceasefire is the story of the day. A two-week truce was struck just an hour before Trump’s deadline to escalate expired, with Iran agreeing to safe passage through the Strait of Hormuz in exchange for a halt to the US-Israeli bombing campaign that’s been running for 40 days. This is consequential for energy markets first and foremost — Brent crude dropped as much as 15% on the news — but the durability of the deal is genuinely uncertain. Iran is already saying talks in Pakistan don’t guarantee a permanent end to hostilities, and as the BBC notes, the path to this truce may have permanently shifted how allies and rivals read American reliability.

The oil move matters directly. A 15% drop is a significant deflationary pulse for the global economy, and it will feed through to UK fuel costs and headline CPI fairly quickly. Worth watching whether the MPC adjusts its inflation calculus if the ceasefire holds.

Starmer is heading to the Middle East to “support and sustain” the truce — sensible optics, modest substance. The UK has limited leverage here but being present matters for trade relationships in the Gulf and for any eventual reconstruction diplomacy.

The BBC’s framing that this deal came “at a high cost” — meaning concessions that signal American strategic retreat — echoes a Rafael Behr piece in the Guardian arguing that Europe cannot count on a post-Trump America returning to the old order. Both are worth reading together. The argument that the US’s reliability as a security guarantor is structurally damaged, regardless of who wins in 2026 or 2028, is gaining serious analytical weight.

On tech: US agencies (FBI, NSA, CISA) have issued a joint advisory warning that Iranian hackers have escalated attacks on American critical infrastructure in direct response to the war. With a ceasefire now in place, watch whether this activity continues or pauses — persistent cyber operations would be a signal that Iran isn’t treating the truce as genuine.

A $1.3bn VC fund from Eclipse focused on “physical AI” — robots, industrial systems, autonomous hardware — is a useful data point on where serious money thinks the next wave of AI value creation sits. Less chatbot, more factory floor.

Watch over the next 48 hours: Whether Iran’s “conditional” framing of the Hormuz reopening translates into actual shipping movement, and whether oil holds its losses or bounces on scepticism about the truce’s longevity.
