The National Institute of Economic and Social Research (Niesr) has revised its growth projections for the UK, signalling a concerning economic landscape as the fallout from the ongoing conflict in Iran begins to take its toll. The thinktank has lowered its growth estimates for 2026 by 0.5 percentage points to 0.9%, and for 2027 by 0.3 percentage points to 1%. This downgrade reflects a broader trend of instability that threatens the nation’s economic recovery.
Economic Pressures from Global Conflicts
Niesr’s findings highlight a bleak outlook for the UK economy, predicting a potential £35 billion hit this year, which could push the nation towards recession. The escalation of tensions in the Middle East, particularly the Iran conflict, has exacerbated existing pressures on the economy, making it increasingly difficult for the government to maintain fiscal stability.
Chancellor Rachel Reeves acknowledged the severity of the situation, stating that “nothing is off the table” as the government considers introducing a targeted support package to assist households dealing with rising energy costs. This statement underscores the urgency of the situation as families brace for increased financial strain.
Inflation and Interest Rates: A Balancing Act
Niesr’s report warns that the UK is highly vulnerable to global energy price shocks, a reality underscored by the current situation. Even in a best-case scenario, the economy is expected to grow at a slower pace, with inflation pressures mounting. The thinktank projects that if oil prices surge to $140 a barrel, inflation could rise above 5%, prompting the Bank of England to consider a significant interest rate hike, potentially the largest since the early 1990s.
On Tuesday, Brent crude was trading at around $111 a barrel, which, while lower than the worst-case scenario, still poses significant risks for the UK economy. Niesr predicts that even under more optimistic conditions, the Bank of England may raise interest rates from 3.75% to 4% in July. This scenario is further complicated by the upcoming policy meeting, where a rate increase cannot be ruled out.
Local Elections and Political Pressure
As Labour faces mounting pressure ahead of local elections, the economic forecast presents a formidable challenge for the party and its leaders. Niesr estimates that the economic fallout from the Iran conflict could add nearly £24 billion to government borrowing by the decade’s end, diminishing Reeves’s fiscal space significantly. Such developments could undermine Labour’s financial strategies and exacerbate public scrutiny.
Stephen Millard, deputy director at Niesr, noted the precarious situation, suggesting that current assumptions about oil prices may be overly optimistic. He remarked, “Either way, the [Bank’s] monetary policy committee is going to have to raise rates this year, and the chancellor is going to have some very tough calls.”
The Broader Economic Landscape
The rising costs of borrowing are evident, with yields on 10-year UK government bonds surpassing 5% this week, the highest levels seen in years. This increase reflects investor concerns about the UK’s economic trajectory as inflation continues to challenge policymakers. Reeves has emphasised the importance of targeted support, arguing against blanket measures that could exacerbate inflation and lead to higher interest rates.
Why it Matters
The revisions in the UK’s economic growth forecasts underscore the intricate interplay between global events and domestic financial health. As the conflict in Iran continues to unfold, the implications for the UK economy could be profound, impacting everything from household budgets to government fiscal policies. The government’s response will be critical in navigating these turbulent waters, and citizens are left wondering how these changes will affect their daily lives. With rising energy costs and the spectre of recession looming, the stakes are high for the UK’s economic future.
