UK Faces Steepest Growth Cut Among G20 Due to Iran War

• The UK is expected to see the largest reduction in economic growth among G20 countries due to the Iran war, with growth forecast to fall to 0.7% in 2026 from a previous estimate of 1.2%.

• The OECD has downgraded UK growth projections due to rising energy prices and global oil supply disruptions, with a prolonged conflict potentially causing significant energy shortages and higher food prices according to analysis.

• The UK's economy is particularly vulnerable to the war, as it relies heavily on international trade and fuel imports, making it more exposed to global energy shocks.

The OECD has revised UK inflation forecasts upward to 4% for 2026, driven by surging energy prices and disrupted supply chains from the Middle East conflict.

What Impact Is the Iran War Having on the UK Economy?

The UK government's official growth forecast has also been reduced due to the war, with the Office for Budget Responsibility acknowledging the economic challenges. The OECD emphasized the need for targeted policies to support households and businesses affected by energy price rises.

Rising energy prices are already being felt in the UK, with gas prices nearly doubling and inflation expectations rising sharply among consumers. This has led to increased costs for retailers and businesses, with some anticipating price increases to offset rising expenses.

What Are the Risks for Global Economic Stability?

Prolonged high energy prices could dampen global economic growth and increase inflationary pressures, according to the OECD. Disruptions to Middle East exports and higher energy prices may worsen the global economic outlook, particularly for energy-dependent nations like the UK.

The OECD also warned that sustained energy shocks could force central banks, including the Bank of England, to reconsider monetary policy, potentially leading to further inflation and limited rate cuts.

What Is the Outlook for UK Inflation and Policy Response?

The UK's current inflation rate of 3.0% is considered misleading as it reflects pre-war conditions. Analysts predict inflation will likely rise above 4% in the coming months due to ongoing energy price increases and supply chain disruptions.

The Bank of England faces the challenge of managing inflation without harming economic growth, with some experts suggesting a potential rate hike if inflationary pressures persist. The UK government has ruled out broad-based energy support measures but has emphasized fiscal discipline to manage risks.
