UK Economy Sees Unexpected 0.3% Growth in March Amid Iran War

The UK economy defied expectations by growing 0.3% in March, according to the Office for National Statistics (ONS), despite the challenges posed by the Iran war. This growth, driven by a strong services sector, including computer programming and advertising, contradicts economists’ predictions of a 0.2% contraction. Chancellor Rachel Reeves attributed the success to the government’s economic plan, emphasizing it as a reason to maintain stability. However, economists caution that the war’s full impact has not yet been felt, warning of potential slowdowns and increased borrowing. The UK now leads G7 nations in GDP growth for the first quarter of 2026, ahead of pending Japanese data.

The growth comes amidst higher energy costs due to the war, which had been expected to dampen economic activity. Instead, the services sector expanded broadly, with GDP per capita increasing by 0.9% year-over-year. Experts like Rob Wood advise caution, suggesting the growth might be inflated by companies preparing for supply disruptions. Simon Pittaway of the Resolution Foundation forecasts the war will slow growth, reduce household incomes, and increase government debt.

Politically, the timing of the positive economic news could support Prime Minister Sir Keir Starmer’s position amid a potential leadership challenge, with the government arguing for the efficacy of its economic strategy.
