The UK budget is facing severe pressure as the ongoing Iran war drives up oil prices and inflation, according to a leading thinktank. The National Institute of Economic and Social Research (NIESR) warns that Prime Minister Andy Burnham must navigate “very difficult trade-offs” in the next autumn budget. With oil prices briefly exceeding $100 per barrel and the Strait of Hormuz nearly closed, the economic outlook has darkened.
How the Iran War Affects the UK Economy
The conflict in the Middle East has disrupted global energy markets, pushing inflation to an expected 3.8% over the next seven months. The NIESR projects that Chancellor John Healey will need to find an extra £24 billion by the end of the decade to maintain public services and welfare payments. This is a sharp increase from earlier forecasts, as the government’s fiscal headroom shrinks from £7 billion to just £3 billion.

The Impact on Growth and Spending
Economic growth is expected to slow to 1.1% this year and remain at that pace through 2027. The thinktank estimates that the UK will lose £28 billion in growth over two years compared to January forecasts. Higher borrowing costs, already the highest in the G7, and cost-of-living pressures compound the challenge. David Aikman, NIESR director, warns against increasing borrowing to ease the strain, calling it a mistake that would lead to future crises.
| Metric | Previous Forecast | Current Forecast |
|---|---|---|
| Inflation Rate | 2.5% | 3.8% |
| Fiscal Headroom | £7bn | £3bn |
| GDP Growth (2025) | 1.5% | 1.1% |
| Extra Spending Needed by 2030 | N/A | £24bn |
Key Takeaways from the NIESR Report
- Oil price surge from Iran war drives inflation above 3.8%.
- UK chancellor faces £24bn shortfall for maintaining services.
- Growth downgraded by 1.1% this year and next.
- Borrowing to fund public spending is risky, says thinktank.
- Cost-of-living crisis persists, especially for low-income households.
What This Means for UK Households
Higher inflation erodes purchasing power, while slower growth could lead to job losses and reduced public services. The government must balance spending commitments with fiscal discipline. Analysts recommend targeted support for the most vulnerable rather than broad stimulus.
FAQ
How does the Iran war affect UK oil prices?
The conflict disrupts supply through the Strait of Hormuz, a key chokepoint for oil tankers. This pushes global oil prices above $100 per barrel, increasing costs for UK consumers and businesses.
What is the UK government's fiscal headroom?
Fiscal headroom refers to the spare capacity in the budget above existing spending commitments. The NIESR estimates it has shrunk from over £7bn to near £3bn due to higher inflation and borrowing costs.
Will the UK raise taxes to cover the budget shortfall?
The thinktank advises against increased borrowing and suggests difficult trade-offs, which may include tax rises or spending cuts. No final decisions have been announced yet.
In summary, the Iran war is creating a challenging economic environment for the UK. With inflation rising, growth slowing, and public finances under strain, policymakers face tough choices. Stay informed as the situation evolves to better manage your personal finances and investments.
