The Iran War’s Shadow Over Britain’s Budget

The latest analysis from the National Institute of Economic and Social Research (NIESR) paints a stark picture: the UK government is facing a perfect storm of economic pressures due to the ongoing conflict in the Middle East. As new Prime Minister Andy Burnham navigates his first budget, he will be forced to make some very difficult choices.

The NIESR’s forecast is clear: inflation is set to rise to 3.8% over the next seven months, forcing Chancellor John Healey to find an extra £24 billion by the end of the decade to maintain services and real-terms welfare payments. This is a staggering figure that highlights the significant impact of the Iran war on the UK’s economy. The thinktank has cut its forecast for the chancellor’s spending headroom in the budget from just over £7 billion to nearer £3 billion – a drop of £4 billion.

The economic cost of this conflict cannot be overstated. The NIESR predicts that the UK will suffer £28 billion in lost growth over two years compared with forecasts in January, as higher energy prices and uncertainty weigh on the economy. This is a sobering reminder of the true price of military intervention – and one that should give policymakers pause.

New commitments on defense or household support must be funded through taxation or savings elsewhere, not through further borrowing, according to the NIESR. Piling more debt onto the already crippling burden of Britain’s national debt will only exacerbate future economic shocks. The government’s total debt has reached almost £3 trillion – 95% of annual national income – and shows no signs of abating.

The NIESR’s director, David Aikman, is right to caution against the temptation to ease the strain on public finances by raising the level of borrowing. This would be a short-sighted decision that ignores the long-term consequences for Britain’s economic stability. The government must take bold action to address these pressing issues.

Burnham’s plans to improve adult social care, provide NHS-style services free at the point of use by 2035, and support the 1 million young people classified as not in education, employment or training are vital initiatives that must be funded sustainably – through taxation, savings, or a combination of both. The road ahead will be treacherous.

The NIESR expects inflation to average 3.1% in 2026, peaking at 3.8% in February 2027 after energy price cap adjustments. This is a prolonged period of economic uncertainty that demands a robust response from policymakers. Burnham’s budget will be a crucial test of his mettle: can he balance the books while delivering on his election promises?

The stakes are high, and the consequences of failure severe. Britain cannot afford to repeat the mistakes of the past when short-sighted fiscal policies led to economic catastrophe. This is a moment for bold action – not timid tinkering. The new Prime Minister must summon the courage to make the difficult decisions needed to secure Britain’s economic future.

The Bank of England officials meet on Thursday, and financial markets expect them to hold interest rates steady before raising them to 4% later in the year. But the real test of Britain’s economic resilience lies not with monetary policy but with the government’s willingness to confront its fiscal challenges head-on. The clock is ticking – will Burnham rise to the challenge?
