The Office for Budget Responsibility (OBR) has raised alarms about the potential for significant repercussions on the UK economy stemming from the ongoing conflict in Iran. Recent spikes in oil and gas prices, attributed to heightened tensions in the Middle East, have cast a shadow over the nation’s inflation outlook, leading to a series of revised economic forecasts.
Inflation Outlook Dims
In its latest projections, the OBR acknowledged that the recent violence in the Middle East could substantially alter its previous predictions. David Miles, a member of the OBR’s budget responsibility committee, indicated that the situation has rendered the inflation outlook “particularly uncertain.” While the organisation had initially anticipated inflation would fall to the Bank of England’s 2% target by early this year, recent developments have complicated this expectation.
“We had central expectations that inflation would return to around 2% by year-end,” Miles stated. “However, the recent volatility has injected a layer of uncertainty into those forecasts.” The OBR now estimates inflation will decrease to 2.3% in 2026, a slight revision from its previous estimate of 2.5%. This adjustment reflects a combination of greater economic slack and declining prices in key sectors such as food and energy.
Growth Projections Adjusted
Alongside inflation adjustments, the OBR has also downgraded its growth forecast for the UK economy. The latest figures suggest GDP will grow by a modest 1.1% in 2026, down from an earlier projection of 1.4%. This reduction is attributed to a slowdown in growth observed in late 2025, a loosening labour market, and lacklustre business survey data.
Despite the immediate challenges, the OBR remains cautiously optimistic about the years ahead. Growth forecasts for 2027 and 2028 have been revised upward, with both years now expected to see a 1.6% expansion. Chancellor Rachel Reeves shared these insights during her spring statement, asserting that while the economy will face hurdles, a recovery is on the horizon.
Unemployment Trends and Government Borrowing
The unemployment outlook has also shifted, with the OBR projecting that the jobless rate will peak at approximately 5.33% in 2026, a slight increase from its earlier forecast of 4.9%. Recent statistics from the Office for National Statistics (ONS) have indicated that unemployment has hit a five-year high of 5.2% as of December.
On a more positive note, the OBR has revised down its borrowing projections through 2031. This is largely due to lower yield on government bonds, which has increased the government’s fiscal headroom to £23.6 billion, up from £21.7 billion reported in November. Experts suggest that improved fiscal conditions may provide some leeway for the Chancellor.
Elliott Jordan-Doak, a senior economist at Pantheon Macroeconomics, remarked, “The Chancellor’s spring statement was largely predictable, reflecting the anticipated ‘boring budget’ that we expected. However, the swift developments in the Middle East could make these fiscal forecasts feel outdated.”
Market Reactions and Future Concerns
The situation in the Middle East poses a potential threat to not only the UK economy but also global markets at large. Peter Arnold, EY UK chief economist, noted that while the UK’s fiscal position has shown signs of improvement, the sustainability of this performance is now in question. “If the conflict in the Middle East continues, we may see increased volatility in global equity markets, which could undermine recent positive trends,” he warned.

The immediate future remains uncertain as the UK balances its economic strategy against the backdrop of geopolitical tensions.
Why it Matters
The implications of the conflict in Iran extend beyond the immediate region, affecting global oil prices and, in turn, the UK economy’s stability. With inflation forecasts and growth projections now more precarious, the government’s fiscal strategy will be put to the test. As the situation develops, both consumers and investors alike will be closely monitoring how these uncertainties unfold, making it crucial for policymakers to navigate these challenges effectively.
