UK Economy Grows 0.3% in March Despite Iran War Shock

BBC Business reported Thursday that the UK economy grew 0.3% in March, defying analyst expectations of a modest contraction. The data, published by the Office for National Statistics, surprised markets still absorbing the early tremors of the Iran war.

Front-Loading Drives Unexpected Expansion

The ONS attributed much of the momentum to anticipatory spending. Consumers and businesses appeared to pull purchases forward, bracing for price increases they expected the conflict to trigger. Car sales, fuel stockpiling and leasing activity were among the sectors where this behaviour was most visible. Retailers reported motorists rushing to fill tanks as petrol prices climbed sharply through the month.

For the full first quarter, the UK economy expanded 0.6%. That is the fastest quarterly pace in a year and, among G7 nations that have reported so far, the strongest reading of the group.

Chancellor Rachel Reeves welcomed the data, telling the BBC the economy “is growing strongly.” She pledged to outline further support for households and businesses affected by the war in the coming week. Reeves also used the briefing to caution that internal Labour Party turbulence over the prime minister’s position risked destabilising the recovery at a critical moment.

Background: IMF Already Flagged UK Vulnerability

The strong March print arrives despite a warning from the IMF last month that Britain faced the steepest economic damage from the Iran conflict among advanced economies. Higher energy import costs and supply-chain exposure were cited as primary risks. Those pressures had not fully fed through in March, analysts say, but are expected to intensify through the second quarter.

Yael Selfin, chief economist at KPMG, told the BBC that households now face mounting strain as energy, petrol and food costs all climb simultaneously. She noted that disruptions to fertiliser supply chains were likely to push grocery prices higher, weighing on disposable incomes and overall demand in the months ahead.

Business Owners Warn Margins Are Shrinking Fast

On the ground, the picture is already darkening. Rory O’Keeffe, commercial director at Essex-based medical device maker Europlaz Technologies, said polymer prices rose five to ten percent almost immediately after the war began. Some suppliers are now refusing to confirm pricing until the moment of delivery, making forward planning nearly impossible.

At a play centre in Chelmsford, co-owner Boston Mace said cost pressures had eclipsed every prior crisis the business survived, including a pandemic, a fire, a flood and a theft. Families are visiting but skipping food purchases, compressing margins further.

The ONS data offers a brief moment of relief. Economists widely expect that relief to be short-lived.
