UK economy grew faster than expected ahead of Iran war

The UK economy saw its biggest monthly rise in February in more than two years, official figures show.

The Office for National Statistics (ONS) said the economy grew by a faster-than-expected 0.5%, while it revised its estimate for January up to 0.1% after previously saying the start of the year had seen no growth.

The figures cover a period before the outbreak of the US-Israeli war with Iran on 28 February, which has caused a major energy shock and experts warn risks a global recession if it is prolonged.

This week the International Monetary Fund (IMF) cut its estimate for UK growth this year, warning it was set to be the hardest hit of the world's advanced economies.

The IMF said it expected the UK to grow by 0.8% this year, down from the 1.3% prediction it had made in January before hostilities began.

The Fund said the downgrade was due to the impact of the war, with fewer interest rate cuts now predicted and an expectation that the impact of higher energy prices will linger into next year.

Most economists had forecast the UK's economy would grow by just 0.1% in February. The monthly increase is the biggest since January 2024 when the economy also grew by 0.5%.

The ONS said the key services sector - which accounts for more than three-quarters of the economy - grew by 0.5%, which was the fourth consecutive monthly rise.

Production output also grew by 0.5% in the month, and construction rose by 1.0%.

In the three months to February, a less volatile measure in comparison to the monthly numbers, GDP also grew by 0.5% - up from 0.3% in the three months to January.

The National Institute of Economic and Social Research called the latest expansion in the economy "sizeable" but said it expected slower growth in March.

Associate economist Fergus Jimenez-England said: "Unfortunately, the latest energy price shock has likely pulled the rug on this momentum, with another year of above-target inflation and a softening labour market likely to come."

Drivers in the UK have seen petrol and diesel prices rise sharply since the war broke out.

Heating oil users have also been hit by steep increases, although households under Ofgem's energy price cap will be shielded from rising energy prices until July.

The economic ripple effects from the conflict could push up inflation - the rate at which prices rise - which before the conflict was on track to fall back to the Bank of England's 2% target by spring.

A pick-up in inflation could also affect interest rates, which prior to the war were expected to fall. However, the prospect of higher inflation has prompted speculation rates will be held steady or even rise this year.

The change in expectations has already had an effect on the mortgage market. Hundreds of deals have been pulled by UK lenders, with average mortgage rates rising to levels not seen since last spring and summer.

Ruth Gregory, deputy chief UK economist at Capital Economics, said the "bumper" growth in February was "probably already extinguished" by the Iran war.

But she said it was encouraging that some of the sectors most exposed to the rise in energy prices had performed well, such energy-intensive mining, transport and retail.

James Murray, Chief Secretary to the Treasury, said growth "only happens when the economy is on solid ground".

"That's why in a changing world our plan to restore stability, boost investment and deliver reform is the right one to build a more stronger more resilient Britain."

Shadow chancellor Sir Mel Stride welcomed the growth but said this week's IMF downgrade showed "our economy is totally unprepared for the recent energy shock".

He said Reeves's choices "have left us poorer, with soaring unemployment and the highest inflation in the G7".

The Liberal Democrats' Treasury spokesperson, Daisy Cooper, said the positive figures were "already in the rear view mirror as the UK is driven into a precarious economic crisis".

She said the Iran war would "add hundreds to family bills" and called for the government to cut 12p off a litre of fuel and reduce transport prices.
