A quiet overnight, but a few things worth flagging.

The TUC is pushing the new Chancellor, John Healey, to order a full review of the OBR ahead of the 28 October Budget. The argument is that the watchdog’s forecasting methodology systematically undervalues the returns on public investment, which constrains what Healey can credibly commit to spending. Whether Healey bites matters a lot for the fiscal headroom debate — if the OBR’s multipliers shift even modestly, the arithmetic of the Budget changes. Worth watching whether the Treasury distances itself from this or lets it run.

Trump has revived his threat to remove Fed governor Lisa Cook, despite the Supreme Court ruling in June that she could remain in post while legal proceedings continue. The timing is pointed — it keeps pressure on the Fed ahead of any rate decisions and signals the White House hasn’t accepted the Court’s position as the end of the matter. Markets have largely priced in Fed independence risk, but any escalation here would move the dollar and rates expectations quickly.

OpenAI has disclosed it paused development of its Astra model after it hit what the company calls a “critical cybersecurity threshold” — meaning the model had reached a capability level where it could independently identify and execute attacks on well-defended real-world systems. This is the first time OpenAI has publicly acknowledged halting a model mid-development on safety grounds of this specific type. It will sharpen the regulatory conversation in Westminster and Brussels about where capability thresholds should sit and who decides them.

Spain has reimposed border controls on Italy in response to Italy’s own controls, which were introduced after roughly 78,000 migrants crossed from Morocco into Ceuta. The tit-for-tat is widening the Sánchez-Meloni rift and putting further strain on Schengen norms. For anyone watching European political risk, this is another data point on the fragmentation of the EU’s internal border framework ahead of the next migration policy cycle.

The Moonshot AI start-up is targeting a Hong Kong listing to raise fresh capital, according to the FT. Chinese AI firms seeking public markets via Hong Kong rather than New York is a pattern worth tracking — it reflects both US listing restrictions and Beijing’s preference for keeping strategic technology capital onshore.

UK heatwave conditions are expected to return next week, with temperatures potentially reaching 35°C. For energy traders, that means demand spikes; for anyone modelling productivity or logistics disruption, it is the fifth such event this year.

The next scheduled event to watch: the UK’s July GDP print is due Monday 11 August.
