The White House has requested an additional $87bn from Congress to fund a military campaign against Iran, a move that threatens to destabilise global markets and ignite a fresh wave of economic uncertainty across Britain. The UK Treasury, in a confidential briefing leaked to the press, has warned that a war in the Middle East could trigger a sharp rise in oil prices, push inflation back above target and damage consumer confidence just as families are beginning to recover from the cost of living crisis.
President Trump’s demand, made in a late-night address from the Oval Office, represents a dramatic escalation in rhetoric against Tehran after weeks of tensions over nuclear enrichment and proxy attacks in the Gulf. The proposed sum, which exceeds the annual budgets of entire federal departments, would cover air strikes, naval deployments and the deployment of ground troops for an initial three month period. Congressional leaders are divided, with Republicans under pressure to fall in line and Democrats accusing the president of dragging the country into an unwinnable quagmire.
But for working families in Manchester, Glasgow and Newcastle, the real alarm is sounding from Threadneedle Street. The Treasury’s internal modelling suggests that a war scenario could push the price of Brent crude above $150 a barrel, adding £800 to the average household energy bill. Petrol prices, already stubbornly high, would climb past £2 a litre. Businesses dependent on imported raw materials would face a fresh squeeze on margins, leading to price rises for everything from clothes to electronics.
The Bank of England would be forced to choose between raising interest rates to curb inflation or holding steady to avoid choking off the fragile recovery. Either path carries pain. Higher rates would hit mortgage holders and renters already struggling with the highest housing costs in a generation. Lower rates would let inflation erode wages, which are only now beginning to outpace price rises after two years of stagnation.
Unions are already mobilising. The RMT and Unite have called emergency meetings to discuss industrial action if the government imposes any cuts to public services to cover the cost of a war effort. The defence budget, already stretched by commitments to Ukraine and the modernisation of the nuclear deterrent, cannot absorb a new conflict without significant trade-offs. Austerity 2.0 is not something the Treasury is willing to contemplate, but the numbers are unforgiving.
Meanwhile, the human cost is impossible to calculate. Military analysts estimate that an invasion of Iran would require at least 150,000 troops, drawing heavily on British reservists and special forces who would be expected to contribute to any coalition operation. The US has already sounded out London about providing logistical support and use of bases on Cyprus and Diego Garcia. The Prime Minister, facing a leadership challenge from his own backbenches, is flying to Washington for emergency talks this weekend.
For ordinary people, the prospect of another Middle Eastern war is a grim reminder that the peace dividend of the 1990s has long been spent. The cost of living crisis that began with the pandemic and was exacerbated by Ukraine is far from over. A conflict with Iran would plunge millions back into fuel poverty, push food prices higher and leave families wondering whether the politicians in Westminster and Washington care about their struggles at all.
This is not a question of foreign policy idealism, but of basic economics. The Treasury’s warning is stark: without a swift diplomatic solution, the contagion will spread from the Gulf to the high street. And for those already counting every penny, there is no room for another shock.
