The Office for Budget Responsibility (OBR) has issued a stark warning regarding the potential fallout from the ongoing conflict in Iran, highlighting that the UK economy could experience a “very significant” impact. As geopolitical tensions rise and energy prices spike, the outlook for inflation remains precarious, with the OBR acknowledging increased uncertainty in its latest projections.
Inflation Projections Under Threat
In a recent update accompanying the Chancellor’s spring statement, the OBR revised its inflation forecast for the year, now predicting a drop to 2.3% in 2026, down from an earlier estimate of 2.5%. This adjustment reflects not only a response to the recent volatility in oil and gas prices but also a broader trend of weakening inflationary pressures, buoyed by falling food and energy costs.
David Miles, a member of the OBR’s budget responsibility committee, stated, “Our central expectation had been that inflation would fall back towards the Bank of England’s 2% target early this year and will be around that level at the end of the year. However, there must be more uncertainty around that right now.” The conflict’s toll on global energy supplies complicates this outlook, as the risk of further spikes in prices looms large.
Growth Forecasts Downgraded
Alongside concerns over inflation, the OBR has also downgraded its economic growth projections for the UK. The economy is now expected to expand by just 1.1% in 2026, a reduction from the previous estimate of 1.4%. This revision is attributed to a slowdown in growth late last year, easing conditions in the labour market, and disappointing data from recent business surveys.
Chancellor Rachel Reeves acknowledged the shift in growth expectations but remained optimistic about a recovery, asserting that growth would accelerate to 1.6% in both 2027 and 2028. She emphasised the government’s commitment to a robust economic strategy, stating, “I have the right economic plan for the UK.”
Unemployment Trends and Fiscal Outlook
Current estimates suggest that unemployment in the UK is set to peak at approximately 5.33% in 2026, a slight uptick from the previous forecast of 4.9%. Recent data from the Office for National Statistics (ONS) revealed that unemployment has already reached a five-year high of 5.2%. Despite these challenges, the OBR anticipates a gradual decline in unemployment rates post-2026.
Moreover, the government’s borrowing projections have been revised downward, potentially easing fiscal pressures. The reduced borrowing costs, spurred by diminishing yields on government bonds, have expanded the government’s headroom to meet fiscal objectives to £23.6 billion, compared to £21.7 billion in the previous budget.
Economist Elliott Jordan-Doak remarked, “There were few major surprises in today’s spring statement, with the Chancellor delivering the well-flagged ‘boring budget’ that we and the market were expecting.” However, he cautioned that the rapid developments in the Middle East could quickly render the current fiscal forecasts outdated.
Market Reactions and Long-Term Implications
Market sentiment remains cautious as analysts reflect on the potential long-term implications of the Iran conflict. Peter Arnold, chief economist at EY UK, noted, “The underlying improvement in the UK’s fiscal position was supported by higher actual and expected tax receipts, driven largely by a stronger equity market performance since November. Yet there may now be doubts around how sustainable this stock market performance can be if the conflict in the Middle East persists.”
With the spectre of geopolitical instability hanging over the economic landscape, UK policymakers face a challenging road ahead. The interplay between rising energy costs and inflationary pressures could influence decisions at the Bank of England, particularly as the central bank aims to maintain its inflation target.
Why it Matters
The unfolding situation in Iran poses a significant risk not just to the UK economy but to global markets as well. As prices fluctuate and uncertainties mount, businesses and consumers alike must brace for potential disruptions. Policymakers will need to navigate these turbulent waters carefully to mitigate adverse effects on growth and employment, all while maintaining fiscal discipline in an increasingly unpredictable global environment.
