2nd March 2026
The recent surge in oil prices, driven by conflict in the Middle East and the closure of the Strait of Hormuz on 1st March 2026, is expected to increase UK inflation and dampen economic growth.
While the UK economy has become significantly less energy-intensive since the 1970s, it remains highly sensitive to global supply chain disruptions and imported fuel costs.
Economic Impact on the UK
Inflation Spike: Analysts warn that if Brent crude remains near $100 per barrel, it could add 0.6 to 0.7 percentage points to global inflation. In the UK, every 10% increase in oil costs historically adds approximately 0.4 percentage points to domestic inflation.
Slower Interest Rate Cuts: The Bank of England had been expected to continue cutting interest rates in March 2026. However, renewed inflationary pressure may force the Bank to maintain a restrictive posture for longer.
Subdued Growth
High energy costs act as a "tax" on consumers and businesses, reducing disposable income and squeezed margins. UK GDP growth for 2026 is already forecast at a modest 0.9%.
Stock Market Volatility
While the broader market may face pressure, UK-listed oil majors like BP and Shell, along with defence stocks, may see share price gains, potentially helping the FTSE 100 outperform other indices.
When Changes Will Occur
The timing of these effects varies by sector:
Immediate (Days): Fuel prices at the pump typically react within weeks of a crude oil spike. Market volatility for oil-linked stocks and safe havens like gold began immediately on March 2, 2026.
Short-Term (Weeks)
Increased transport and logistics costs will begin filtering through supply chains, potentially affecting retail prices for goods by late March or April 2026.
Medium-Term (Months)
The Ofgem energy price cap is already set to fall by 7% on April 1, 2026 (to £1,641 for a typical household) due to previous wholesale declines. However, the current surge could lead to a significant increase when the cap is next reviewed for the July-September period.
