Rachel Reeves braces for ‘bad news’ as US-Iran war to hit UK economy’s GDP growth

Chancellor Rachel Reeves is expected to be dealt another fiscal blow as the British economy appears set to experience another month of stagnation.

The Office for National Statistics (ONS) will release gross domestic product (GDP) data for May on Thursday, with forecasters anticipating either flat growth or a further 0.1 per cent contraction.

 

April saw output shrink by 0.1 per cent, representing the first decline since August 2025 and a marked slowdown from the 0.3 per cent expansion recorded in March.

The US-Israel conflict with Iran has created significant headwinds for the UK economy, with Chancellor Rachel Reeves acknowledging it was “not a war we wanted or joined, but one that will have an impact at home”.
