The détente between Washington and Tehran has sent a shiver through oil markets, with Brent crude sliding 4% this morning. But don't be fooled by the dip in pump prices. The real story for British households is the lagged effect on food costs and energy bills.
The deal, which eases sanctions on Iranian oil exports, adds roughly 1 million barrels per day to global supply. That's a short-term salve for inflation, but it's a bandage on a haemorrhage. The structural drivers of high prices: tight refining capacity, chronic underinvestment in new production, and the green transition's demand for scarce minerals.
The Treasury will welcome any respite from soaring gilt yields, but the consumer's basket is stickier. Food inflation, already at 14%, will take months to moderate as wholesale prices trickle down. Meanwhile, the pound's rally against the dollar offers some succour to importers, but the trade-weighted index remains below pre-pandemic levels.
The Office for Budget Responsibility's fiscal headroom, that elusive creature, may expand by a few billion pounds if oil stays below $80 a barrel. Don't bet on it. Geopolitical risk is a two-way street: this deal could unravel faster than a Libor scandal.
British households should brace for energy bills to remain elevated through 2025. The era of cheap fossil fuels is over. The market is pricing in a new normal where volatility is the only constant.
Central bankers, meanwhile, are caught between the rock of inflation and the hard place of recession. The Bank of England's Monetary Policy Committee will be watching the oil price caps like hawks. For the average family in Manchester or Margate, the bottom line is this: you will feel the pinch at the supermarket till and the thermostat long after the headlines fade.
