UK diesel prices hit 198.32p per litre today and will almost certainly surpass the all-time record of 199.09p over the weekend, according to the RAC. Petrol has climbed nearly 12p in September alone, now averaging 173.6p — a four-year high. Since the Iran War began on 28 February, diesel has risen 55p per litre and petrol more than 40p. These are not marginal moves; they represent a structural repricing of energy costs flowing directly from the Strait of Hormuz disruption through global crude markets into every UK forecourt. Bank of England Governor Andrew Bailey made the implications explicit at an Oxford economics conference. "It's going to be harder to maintain that stance, the longer we have high energy prices," he said, effectively signalling that interest rate rises are now a question of timing, not principle. This puts UK households in a vice: energy costs rising at the pump while mortgage costs rise at the bank. Bailey also disclosed that the BoE is using large language models to test how its communications land with markets — a notable operational detail about central bank modernisation. Oil markets offered a sliver of hope. Brent crude dipped 0.4% to $106.15 per barrel on reports that US and Iranian negotiators in New York are exploring "a phased path out of war." Earlier in the session crude had been down over 1%. The diplomatic signal is real but fragile — prices remain at levels that guarantee continued pump-price escalation for weeks even if a ceasefire materialised tomorrow, given the lag between wholesale and retail pricing. The consumer confidence picture is split across the Atlantic. UK confidence picked up modestly, though there are concerns the recovery is fading as energy costs bite. In the US, the University of Michigan consumer sentiment index dropped to 48.1 in September from 51.7 in August — a four-month low and 12% below a year ago. Republican sentiment is down 20% since January 2026; Democrats down 13%. Buying conditions for durables ticked up slightly, but only because consumers want to purchase before prices rise further — a classic inflation-expectations ratchet. US government borrowing costs continued their march higher. The 30-year Treasury yield hit 5.5185%, a 22-year high not seen since 2004. Yet Wall Street opened up, with the Dow gaining 267 points to 51,617, partly on news that Trump and Xi Jinping agreed a two-month extension of the US-China trade truce. ING's Lynn Song noted the summit delivered "plenty of symbolic goodwill" including pandas but "little substantive progress" on trade barriers, AI competition, or Taiwan. In corporate news, Elon Musk's X reported its first UK revenue increase since the 2022 acquisition — revenues of £46.4m, up 61% on 2024, with pre-tax profits doubling to £1.58m. However, advertising income remained flat at £22.9m; the revenue jump came from inter-company services to its parent, rising from £6.9m to £23.6m. The platform disclosed a $4.5m advertising hit in Q1 from Iran War disruption. X's UK wage bill surged from £14.5m to £47m, driven by £28m in share-based payments for 84 staff. Ofcom is investigating Grok AI's generation of sexualised and child sexual abuse imagery. Elsewhere, Chancellor Healey appointed Labour manifesto writer Ravinder Athwal as senior special adviser ahead of the 28 October budget, fuelling election speculation. Greece's PM Mitsotakis spoke about Athens's push to attract hedge funds after billionaire Chris Rokos announced plans to leave the UK. Santander's banking app went down for customers.
