The UK economy has recorded an unexpected 0.3% growth in March, marking the first full month of the ongoing Iran war. This surprising development suggests that the conflict has not yet taken as severe a toll on economic activity as many had feared. According to the Office for National Statistics (ONS), this performance aligns with recent surveys indicating that UK businesses have managed to sustain momentum despite escalating fuel prices.
Economic Indicators Show Resilience
In March, the UK’s gross domestic product (GDP) grew by 0.3%, a figure that exceeded economists’ forecasts of a 0.2% decline. This follows a revised growth of 0.4% in February, down from an initial estimate of 0.5%, and a stagnation in January at 0%. Over the first quarter of 2026, GDP climbed by 0.6%, a significant improvement from the mere 0.1% growth recorded in the previous quarter, and it reflects a 1% increase compared to the same period last year.
The ONS attributes this growth largely to positive trends across the services sector, particularly in computer programming and advertising, which have both seen robust performance. Additionally, the construction sector has returned to growth, further bolstering overall economic performance.
Consumer Spending and Caution
However, not all sectors are thriving. A notable 2.2% drop in sports, amusement, and recreation activities hints at a cautious consumer sentiment, as households reduce discretionary spending in light of anticipated inflationary pressures. This downturn underscores the potential vulnerabilities within the economy as the conflict in the Middle East continues to unfold.
March’s GDP figures serve as an early indicator that, despite the turmoil stemming from the Iran war, the UK economy is holding up better than many analysts had predicted. The closure of the Strait of Hormuz has led to sky-high oil and gas prices, yet business operations and consumer spending have shown surprising resilience.
Government Response and Future Outlook
Chancellor Rachel Reeves seized on the positive data, asserting that the government’s economic strategy is effective in navigating the challenges posed by the conflict. “The choices I have made as chancellor mean our economy is in a stronger position as we deal with the costs of the war in Iran,” she stated. Reeves also addressed Labour party dynamics, emphasising the need for stability and continuity in economic leadership during turbulent times.
Despite the encouraging figures, the Bank of England has cautioned that higher interest rates may be on the horizon as inflation is expected to rise further. March saw inflation jump to 3.3%, up from 3% in February, with the war contributing significantly to this increase. The bank warns that the energy supply shock could soon impact GDP growth, particularly if consumer incomes and business investments begin to falter.
Mixed Signals for the Future
Looking ahead, economists express caution regarding sustained growth. Yael Selfin, chief economist at KPMG, predicts that the adverse effects of the Iran war will likely become more pronounced in the second quarter, with rising costs and diminishing demand expected to constrain activity.
Fergus Jimenez-England from the National Institute of Economic and Social Research echoed this sentiment, noting that while retail sales and purchasing manager indices have remained stable, these indicators may reflect a temporary rush to spend before anticipated price increases.
Why it Matters
The UK’s unexpected growth amidst the Iran war highlights the complex interplay between geopolitical events and economic performance. While current figures suggest resilience, the looming threat of inflation and potential supply chain disruptions could reshape the economic landscape in the near future. Policymakers and businesses alike must remain vigilant, adapting to the evolving circumstances that could impact the economy’s trajectory in the months to come.
