UK GDP grew 0.3% in March, the first month after the Iran conflict began, defying expectations of a contraction and highlighting sectoral strength.
The United Kingdom’s economy expanded by 0.3% in March 2026, the first month after the outbreak of the Iran war, surpassing analysts’ forecasts of a decline [1]. Growth was driven by both services and output, while production slipped slightly, suggesting a mixed but overall robust performance amid emerging geopolitical shocks.
Key takeaways
The Office for National Statistics reported that the UK’s economy grew by 0.3% in March, marking the first month of growth after the Iran war erupted in April [1]. Economists had expected a contraction, anticipating that the conflict would dampen trade and investment flows. Instead, the data showed a modest expansion, with the services sector—particularly wholesale and retail trade—adding a 0.3% increase to the monthly figure. Output, measured across manufacturing and other non‑service activities, rose sharply by 1.5%, while traditional production fell by 0.2% [1].
Chancellor Rachel Reeves hailed the numbers as proof that “the right economic plan” is taking effect, warning that a leadership contest could “plunge the country into chaos” [1]. Shadow chancellor Mel Stride, however, argued that political turmoil was “destabilising Britain’s economy” [1]. The divergent political commentary underscores the delicate balance between economic performance and political stability.
While the UK’s domestic data suggest resilience, the broader regional outlook remains precarious. Iran entered the war already weakened, with inflation above 50% and a sharply depreciated rial by late 2025 [2]. The conflict has damaged key export sectors—petrochemicals and metals—reducing export revenues that previously generated $25‑30 billion annually [2]. Analysts project that over the next two to four months Iran will face “severe stagflation,” with high inflation, rising unemployment and falling real incomes [2].
Even though the UK’s growth figures do not directly reflect Iranian economic distress, the proximity of the two economies and the potential for disrupted trade routes—particularly through the Strait of Hormuz—could introduce indirect pressures on British businesses reliant on Middle‑East energy supplies. The situation highlights the importance of monitoring how regional instability may translate into supply‑chain and price effects for the UK.

The decline was driven by drops in administration, support, arts, and entertainment, with reports suggesting that the cancellation of sporting events in the Middle East due to the Iran conflict negatively impacted related British firms.
Real GDP grew by 0.7% in the three months to April compared to the preceding three-month period.
The UK total goods and services trade deficit widened by GBP7.7 billion to reach GBP9.9 billion in the three months to April.
The March GDP increase signals that the UK economy can absorb short‑term geopolitical shocks, at least in the immediate term. However, the political commentary warns that domestic leadership disputes could erode confidence and offset these gains. Moreover, the deteriorating economic conditions in Iran—characterised by soaring inflation and export disruptions—pose a risk of longer‑term spillovers, especially for sectors linked to energy and trade. Policymakers will need to balance domestic fiscal strategies with vigilance over external shocks as the region’s instability evolves.
