The UK government is facing a formidable challenge as rising oil prices and inflation, driven by the ongoing conflict in Iran, threaten to complicate the upcoming autumn budget. Analysts from the National Institute of Economic and Social Research (NIESR) warn that Prime Minister Andy Burnham will inherit a precarious fiscal landscape, requiring tough decisions to navigate a burgeoning economic crisis.
The Economic Fallout from the Iran Conflict
Since the strait of Hormuz has been largely closed since March, oil prices have surged, briefly exceeding $100 a barrel. This disruption is anticipated to push inflation to unprecedented levels, projected to reach 3.8% in the next seven months. As a result, Chancellor John Healey will need to identify an additional £24 billion by the end of the decade to maintain essential public services and welfare payments.
NIESR has revised its forecast for the Chancellor’s available spending capacity, slashing it from over £7 billion to approximately £3 billion. The Office for Budget Responsibility had previously estimated that the Treasury had around £22 billion in spare funding over and above existing commitments. However, with energy prices soaring, the economic growth outlook has dimmed, with the UK expected to see a mere 1.1% growth rate this year—down from earlier predictions.
A Challenging Inheritance for Burnham
David Aikman, director of NIESR, highlighted the tough terrain that Burnham must navigate, citing inflation’s erosion of public spending and the UK’s already high borrowing costs. He warned against the temptation to fund new initiatives through increased borrowing, suggesting that such a move could exacerbate financial woes in the future.
Burnham, who recently took office, has already made several ambitious pledges, including reforms to adult social care and enhanced support for over a million young people currently classified as NEET (not in education, employment, or training). However, with total government debt nearing £3 trillion—equivalent to about 95% of national income—any reliance on borrowing could further inflate the debt burden.
Forecasting Future Challenges
Stephen Millard, NIESR’s head of macroeconomic forecasting, noted that while the UK economy showed resilience in the first half of the year, a slowdown is imminent. Even if peace is restored in the Middle East soon, inflation will likely continue to rise. The Chancellor will be faced with tough choices on funding recent policy announcements, from VAT cuts on electricity to subsidised transport fares.
Millard suggested prioritising tax reforms over raising existing taxes, advocating for a land value tax to replace council tax and stamp duty. He highlighted the importance of addressing tax avoidance among wealthy individuals and corporations to bolster revenue.
The Inflation Outlook
NIESR’s latest economic outlook predicts that inflation will average 3.1% in 2026, peaking at 3.8% in February 2027 following adjustments to energy price caps. The thinktank now estimates it will take until early 2029 for inflation to revert to the Bank of England’s target of 2%, a delay from its previous forecast of 2028. As financial markets brace for the Bank of England’s upcoming meeting, analysts expect interest rates to remain steady for now, with a potential increase to 4% later in the year.
Why it Matters
The intersection of rising oil prices and inflation, exacerbated by geopolitical tensions in the Middle East, poses significant risks for the UK economy. The challenges facing Prime Minister Burnham could reshape public service funding and welfare commitments, impacting millions of citizens. As the government grapples with these economic pressures, the decisions made in the forthcoming budget will not only define Burnham’s leadership but also determine the financial stability of the UK for years to come.
