Good morning. A few things worth your attention before the week gets going.

The FT’s piece on the “Italianisation” of Britain’s finances is worth sitting with. The framing — investors drawing parallels between UK fiscal credibility and Italy’s history of political drift and budgetary slippage — is pointed. It lands at a moment when gilt markets are already sensitive to any signal that the government’s spending envelope is under pressure. Nothing has blown up, but the tone from overseas investors is clearly souring, and that matters for how the DMO’s autumn issuance is received.

On UK politics, Starmer’s position is wobbling loudly enough that David Lammy felt the need to go on the record denying any departure timetable. The trigger is the Makerfield by-election next month, where Andy Burnham is expected to stand. Lammy called the leadership speculation a “spectacular own goal.” Whether or not Starmer is actually going anywhere, the noise itself is a distraction from the spending review and creates uncertainty around the policy agenda for the second half of the year.

The FT’s Iran war fuel cost story is the global macro item that matters most this week. The piece puts the additional US petrol and diesel bill from the conflict at $40bn — more than the cost of repairing the country’s bridges or fixing air traffic control. Separately, the FT reports that mortgage costs are rising in North America and Europe despite rates being on hold, with Middle East conflict cited as a driver through energy and risk-premium channels. That’s a meaningful transmission mechanism to watch if the conflict persists or escalates.

On Iran specifically, Trump has sharpened his language — “the clock is ticking” and there “won’t be anything left” if a deal isn’t reached. The US Treasury Secretary is simultaneously pushing G7 partners to adopt US-led sanctions. The UAE has attributed a drone strike near a nuclear plant to Iran or its proxies. The combination of rhetorical escalation, sanctions pressure, and physical incidents in the Gulf raises the tail risk on energy supply meaningfully.

Russia appears to be losing ground in Ukraine for the first time since October 2023, according to The Economist’s territory tracker. It’s a single data point, but if it marks a genuine inflection it has implications for how long Western defence spending commitments hold politically and how the eventual negotiating dynamic shapes up.

On tech, the Musk-OpenAI trial is entering its final days with trustworthiness of Sam Altman as a central theme. Nothing dispositive yet, but the outcome will affect how OpenAI’s governance is perceived ahead of any IPO process.

UK CPI data for April is due Wednesday morning — the first read since the energy price cap rise in April, and the number that will most directly shape expectations for the Bank’s June meeting.
