The UK government has stepped up contingency planning for supply chain disruptions linked to the Iran war, with officials monitoring stock levels across critical sectors. The more pointed concern is the NHS’s exposure to Gulf petrochemical supply chains — syringes, IV bags, gloves, catheter casings, active pharmaceutical ingredients — much of which moves through shipping lanes now effectively stalled. This isn’t a theoretical risk; NHS chiefs are already flagging it. For anyone with healthcare or industrials exposure, the question of how long the Gulf standstill persists is no longer background noise.

The Iran peace process has hit another wall. Trump called off the planned trip by Steve Witkoff and Jared Kushner to Pakistan for indirect talks with Tehran. Iran had already said there were no plans for a direct meeting. Both sides appear to be walking away from the table simultaneously, which makes a near-term de-escalation harder to price in. The Strait of Hormuz demining timeline — weeks even with allied naval support, per FT reporting — remains the binding constraint on any shipping normalisation.

On Keir Starmer, the weekend brought open briefing from Labour MPs about his judgement and leadership. Starmer’s response was to insist the “majority” of the parliamentary party backs him. That’s a low bar to be publicly asserting, and the fact he felt the need to say it at all tells you something about where internal confidence sits heading into a week that will likely include further pressure on his economic positioning.

Google has committed up to $40 billion into Anthropic, following Amazon’s investment earlier in the week. The scale is notable — this is Google effectively buying strategic optionality in the frontier model race while also being a competitor through Gemini. For anyone thinking about cloud infrastructure and AI compute concentration, the Anthropic cap table is now a proxy for the entire hyperscaler rivalry.

Google Cloud’s CEO Thomas Kurian separately made the case this week that proprietary AI chips and in-house models give Google a credible path to close the gap on AWS and Azure. The Anthropic investment and the cloud growth story are connected: Google needs Anthropic’s model traction to pull enterprise workloads onto its infrastructure.

The Washington correspondents’ dinner shooting incident is worth noting for context — Trump was unharmed, a suspect is in custody on firearms and assault charges, and there is no indication of a broader threat. It does not appear to have market implications.

The IMF’s World Economic Outlook update is due Monday, which will be the first formal multilateral growth forecast revision to incorporate the tariff escalation of the past month.
