The ongoing conflict in Iran could have a profound impact on the UK economy, according to the Office for Budget Responsibility (OBR), with inflation forecasts now shrouded in uncertainty. In light of recent spikes in oil and gas prices, the budget watchdog has adjusted its economic projections, indicating a slower growth trajectory for 2026 and a rise in unemployment over the next few years.
Inflation Outlook Gloomy Amid Middle East Turmoil
The OBR has issued a stark warning regarding the potential fallout from the escalating violence in the Middle East, stating that such conflicts could dramatically affect both global and national economic stability. Following attacks in the region, the OBR expressed concerns that inflation would be particularly unpredictable, especially in light of rising energy costs.
David Miles, a member of the OBR’s budget responsibility committee, noted that the outlook for inflation has become increasingly uncertain in recent days. “What will happen to inflation is particularly uncertain in the past few days,” he said. Initially, the OBR had anticipated that inflation would drop to the Bank of England’s target of 2% by the end of this year, but recent developments suggest that this may no longer be the case.
Growth and Unemployment Projections Revised
The OBR has also revised its growth forecasts downward, predicting the UK’s GDP will increase by just 1.1% in 2026, down from a previous estimate of 1.4%. This adjustment is linked to a slowdown in growth late last year and a loosening labour market. The unemployment rate is now projected to peak at approximately 5.33% in 2026, a notable increase from earlier forecasts.

Chancellor Rachel Reeves addressed these findings in Parliament, asserting that while the economy is expected to grow more slowly than initially thought, there would be recovery in subsequent years, with growth rates of 1.6% anticipated for both 2027 and 2028.
Fiscal Health Shows Signs of Improvement
Despite the grim outlook for inflation and growth, the OBR has lowered government borrowing projections for the years leading up to 2031, providing a potential silver lining for the Chancellor. The reduction in borrowing costs, attributed to a decline in government bond yields, has expanded the government’s fiscal headroom to £23.6 billion, compared to £21.7 billion in November.
Elliott Jordan-Doak, a senior economist at Pantheon Macroeconomics, remarked that the spring statement by the Chancellor aligned with expectations, calling it a “boring budget.” However, he cautioned that the fiscal forecasts may appear outdated due to the rapid developments occurring in the Middle East.
Market Reactions and Future Considerations
Peter Arnold, EY UK chief economist, highlighted that the UK’s improved fiscal position has been bolstered by stronger tax receipts, primarily driven by improved equity market performance. However, he warned that prolonged conflict in the Middle East could jeopardise this market stability, leading to increased volatility.

As the situation continues to evolve, experts and policymakers alike will need to carefully monitor how these international developments affect the UK’s economic landscape.
Why it Matters
The ramifications of the Iran conflict extend far beyond the region, with the potential to destabilise the UK economy at a critical juncture. Fluctuations in inflation and growth projections can significantly impact everyday consumers, influencing everything from the cost of living to job stability. As the situation unfolds, it is crucial for both the government and the public to remain vigilant and informed about how these global events may reverberate at home.
