UK Economy Faces Energy Price Shock as Iran War Drives Oil Surge and IMF Cuts Growth Forecast
The UK economy is facing significant headwinds from the global energy price shock triggered by the Middle East conflict, with the International Monetary Fund cutting Britain's growth forecast by more than any other G7 nation, even as February GDP data showed stronger-than-expected growth of 0.5% before the crisis escalated.
Background
The ongoing conflict in the Middle East, particularly the Iran war and the closure of the Strait of Hormuz — a critical choke point for approximately 20% of the world's oil trade — has sent energy prices surging globally. Brent crude futures have risen sharply, with the actual cost to acquire a barrel estimated at between $120 and $160 when insurance and shipping premiums are factored in.
Key Developments
UK Chancellor Rachel Reeves has announced expanded support for energy-intensive businesses, and the government is planning to scrap an extra carbon charge paid by fossil fuel power stations — a move welcomed by industry. Ministers have also set out a £600 million scheme to help businesses with energy bills. However, the IMF has cautioned against "generous" energy support packages for households, warning they could increase demand and worsen the crisis.
The FTSE 100, which hit the 10,000 mark for the first time earlier in 2026 — hailed by Reeves as a "vote of confidence in Britain's economy" — is now facing volatility. Tesco has warned that its profits could fall due to uncertainty caused by the Iran war, while EasyJet has flagged that rising oil prices will hit its profits. Intertek, the FTSE 100 testing and inspections company, rejected a £7.9 billion takeover bid from a Swedish private equity firm.
The British Business Bank this week announced its largest-ever fund commitment: a £100 million cornerstone investment in Apposite Healthcare Growth I, a fund supporting the growth of UK-based health technology companies. The investment aims to address a shortage of scale-up capital in the life sciences sector.
Why It Matters
The energy price shock is threatening to derail the UK's economic recovery. Analysts at JP Morgan warn that the oil price spike could make the February growth figures short-lived, while Capital Economics suggests growth may slow to a crawl. The IMF's decision to cut the UK's forecast by more than any other G7 nation underscores the particular vulnerability of the British economy to energy price volatility.
What's Next
Unions and business groups are scheduled to meet the government to discuss the cost-of-living crisis. The Bank of England's Monetary Policy Committee will be closely watching inflation data as it weighs the timing of any further interest rate decisions. Read more at The Guardian.
