The UK is set to face one of the highest inflation rates this year in the G7, as rising global energy costs linked to geopolitical tensions, including those involving Iran, put pressure on prices and growth. However, there is no confirmed OECD statement explicitly ranking the UK as the second-highest after the United States, and such rankings vary depending on forecasts and updates. The OECD has indicated that external shocks, particularly in energy markets, are contributing to inflationary pressure while also weakening growth, creating conditions similar to a stagflationary environment.
What the OECD says
The OECD’s interim outlook suggests UK inflation could remain above earlier expectations, though specific figures such as a 4 per cent average for 2026 and a precise revision from 2.5 per cent should be treated cautiously as forecasts change frequently across reports. Growth projections for the UK have been revised downward in recent assessments, reflecting weaker demand and higher input costs. The OECD has highlighted that energy market volatility, particularly in oil and gas, is a key driver of inflation, while supply chain pressures, including fertiliser costs, can contribute to food price increases over time. Across the G7, inflation outcomes differ by country, and while the United States may face strong energy-related pressures, it is not consistently ranked as having the highest inflation in all OECD projections. Similarly, UK growth is expected to be relatively weak compared to some peers, though exact rankings alongside countries such as Italy depend on evolving forecasts.
Why the UK is exposed
The UK is relatively exposed because it relies on imported energy and key industrial inputs that influence domestic prices. Increases in oil and gas prices tend to pass through into transport, manufacturing, and household costs. Global instability affecting energy supply routes can therefore have a noticeable impact on inflation dynamics. This exposure is more significant in a context of modest underlying growth and fragile business confidence. Business surveys have pointed to slower activity alongside rising input costs, suggesting that inflationary pressure is not purely temporary but linked to broader economic conditions.
Policy implications
For the Bank of England, the situation creates a policy trade-off. Elevated inflation would normally justify tighter monetary policy, but weaker growth complicates that response, particularly when inflation is driven largely by external energy prices rather than domestic demand. Interest rate decisions, therefore, need to balance controlling inflation against the risk of slowing the economy further. For the government, the OECD’s analysis underlines that global energy shocks linked to geopolitical tensions are having economic consequences. Policy responses may include strengthening energy resilience, providing targeted support to households and businesses, and improving supply chain stability. However, such measures cannot fully offset global price pressures. The broader outlook suggests a period where inflation remains relatively elevated while growth stays subdued, with external shocks playing a significant role.
