UK Economy Grew Faster than Expected in February Ahead of Iran War

Why It Matters

The unexpected February growth offers a brief reprieve for a struggling economy, but the IMF downgrade and rising energy costs threaten to reignite inflation and stall recovery, influencing monetary policy and consumer finance.

Key Takeaways

• UK GDP rose 0.5% in February, biggest monthly gain since Jan 2024
• Services sector contributed 0.5% growth, covering finance, retail, hospitality
• Construction output jumped 1.0%, while production rose 0.5% in February
• IMF cut UK 2024 growth forecast to 0.8% amid Iran war energy shock
• Mortgage rates surged, prompting lenders to pull hundreds of deals

Pulse Analysis

The February GDP surprise reflects a narrow window of resilience in the UK’s post‑pandemic recovery. While economists had penciled in a modest 0.1% rise, the Office for National Statistics reported a 0.5% increase, the strongest monthly expansion since early 2022. This uptick arrived just before the Iran‑Israel conflict sparked a global energy shock, prompting the International Monetary Fund to slash its 2024 growth projection for the UK to 0.8%. The IMF’s revision underscores how geopolitical volatility can quickly erode fiscal optimism, especially for an economy already grappling with elevated inflation.

Sector‑by‑sector analysis shows the services industry—accounting for three‑quarters of UK output—matched the overall 0.5% gain, buoyed by finance, retail and hospitality. Meanwhile, construction posted a 1.0% surge and production rose 0.5%, indicating that energy‑intensive activities such as mining and transport are holding up despite higher fuel costs. However, the war‑driven spike in petrol, diesel and heating‑oil prices threatens to reignite price pressures, potentially pushing inflation back above the Bank of England’s 2% target and complicating the central bank’s rate‑setting calculus.

Policy implications are already materialising. Mortgage rates have climbed to levels not seen since last spring, prompting lenders to withdraw hundreds of deals and tightening credit conditions for households. Politicians from both sides of the aisle cite the data to argue for fiscal stimulus, yet the Bank of England remains cautious, prioritising inflation control over growth support. As the energy shock persists, analysts expect the February boost to fade, leaving the UK vulnerable to a slowdown that could test the resilience of its labour market and consumer spending in the months ahead.
