The most significant development overnight is the escalation in the US-Iran conflict. American strikes have hit infrastructure in southern Iran — airports, bridges, a rail station — and US marines have boarded a vessel in the Strait of Hormuz. Iran has retaliated by striking targets across the Gulf, with Al Jazeera reporting hits on Bahrain, Qatar, Oman, Jordan and Syria. A tanker was also struck by an unknown projectile near Khasab, just east of the strait, sustaining minor structural damage. The UKMTO confirmed the crew are safe and the vessel is proceeding to port. With the strait now actively contested, energy traders will be watching shipping flows closely. Any sustained disruption to tanker transit would feed directly into oil prices and European energy costs.

At home, Andy Burnham is being formally confirmed as Labour leader today at a special conference. His shadow cabinet is already generating friction — multiple Labour MPs, some on the record, are questioning the appointment of Shabana Mahmood as shadow chancellor, citing a lack of economic profile and what one senior ally described as limited collaborative instincts. Whether Burnham can hold his coalition together matters for how credible Labour’s fiscal positioning looks heading into the next election cycle.

China has formally objected to the British Steel nationalisation. Beijing’s response was predictable but worth noting for anyone tracking the trajectory of UK-China economic relations, which have been deteriorating steadily.

The Philadelphia semiconductor index is on course for its worst weekly performance since last April’s liberation day selloff, as the AI trade goes into reverse. No single catalyst is being cited, but the move is broad enough to suggest positioning rather than a specific news event.

Trump Media is reportedly planning to sell high-speed access to the president’s Truth Social posts — milliseconds ahead of general availability — to large trading firms. If accurate, this is a formalised market-moving information product built around presidential communications. The regulatory and market integrity questions are obvious.

SpaceX aborted its second Starship V3 launch attempt after engines failed to ignite at the point of ignition. The stock dropped more than 4% in after-hours trading before recovering some ground. The company said the next attempt is likely within a few days.
