UK GDP posts 0.4% Q2 growth as Iran war tests resilience
Quarter‑two GDP rose 0.4% as the services sector steadied the UK economy, but analysts warn the lift may be fleeting.
The Office for National Statistics said the United Kingdom’s gross domestic product expanded by 0.4 per cent between April and June, with a surprise 0.3 per cent jump in June that outpaced most forecasts. The figure matches Bloomberg’s consensus for the quarter but revises May’s flat growth back to zero.
Why the modest gain matters
Even as the war in Iran pushes oil prices higher, the British economy has managed to absorb the shock, suggesting households and firms are still coping with elevated costs. Yet the uplift stems partly from one‑off events, a World Cup run and an unusually warm summer, that are unlikely to repeat.
The services sector was the main driver, posting a 0.5 per cent rise over the three‑month period. Manufacturing held steady, while construction eked out a modest 0.3 per cent gain.
"The economy has proven resilient, but seasonal quirks are flattering activity in the first half of the year," said George Brown, senior economist at Schroders.
What policymakers face
Yael Selfin, chief economist at KPMG, warned that "temporary tailwinds are likely to fade, and higher prices continue to squeeze households’ purchasing power". Liz McKeown of the ONS added that growth slowed in the second quarter after a strong start to 2026, signalling a potential cooling trend.
Prime Minister Andy Burnham and Chancellor John Healey now confront a budget that must balance fiscal pressure with the risk of a prolonged Strait of Hormuz blockage. Treasury models suggest GDP could slip to 0.3 per cent growth if the waterway stays closed, while the Bank of England has signalled a possible rate hike under the same scenario.
Independent forecasters at EY and Capital Economics flag a recession risk if oil and gas supplies from the Gulf remain disrupted, noting that government spending has been a key growth engine. The upcoming budget is expected to focus on devolution and regional investment, but limited fiscal headroom may force tax increases of around £25bn.
Looking ahead
Analysts agree that the next few months will test whether the economy can sustain its pace without the boost from seasonal events. Higher energy costs and tighter borrowing conditions are set to filter through to both consumers and businesses, likely tempering growth as the year progresses.
