The National Institute of Economic and Social Research (Niesr) has revised its growth projections for the UK, highlighting a 0.5 percentage point reduction for 2026, bringing the forecast down to 0.9%, and a 0.3 percentage point drop for 2027, now estimated at 1%. This downgrade emerges against a backdrop of escalating economic pressures primarily driven by the ongoing conflict in Iran, suggesting significant implications for the UK’s fiscal landscape.
Economic Impact of the Iran Conflict
Niesr warns that the financial repercussions from the war in Iran may result in a staggering £35 billion hit to the UK economy this year, coupled with an increased risk of recession. The think tank points to the direct correlation between rising energy prices and the economic health of the nation, asserting that even under optimistic conditions, growth rates for the next two years are expected to remain sluggish.
Chancellor Rachel Reeves has acknowledged the gravity of the situation, stating that “nothing is off the table” as the government explores options for a targeted support package aimed at alleviating the pressure on households grappling with surging energy costs.
Inflationary Pressures and Monetary Policy Challenges
In its assessment, Niesr has highlighted that the UK is acutely vulnerable to global energy shocks, exacerbated by the conflict. David Aikman, director of Niesr, remarked, “This is a serious blow to the government’s mission to get the UK economy growing again.” The report emphasises that even if hostilities were to subside quickly, households would still face the burden of elevated energy prices, which could diminish disposable income and overall economic activity.
Under a pessimistic scenario where oil prices surge to $140 per barrel, the think tank warns that the UK could experience a more severe inflation shock than currently anticipated. Such a scenario could potentially push inflation rates above 5%, compelling the Bank of England to enact its largest interest rate hike since Black Wednesday in 1992, with a potential increase of 1.5%.
Even in a more moderate scenario, Niesr anticipates that the Bank of England will raise interest rates by a quarter point to 4% in July, though speculation surrounds the possibility of an earlier increase.
Local Elections and Political Ramifications
With local elections approaching, the Labour Party, led by Keir Starmer, finds itself under increasing pressure. The economic fallout from the Iran conflict is projected to add nearly £24 billion to UK government borrowing by the decade’s end, substantially eroding Chancellor Reeves’s fiscal headroom. Stephen Millard, Niesr’s deputy director, cautioned that financial markets might be overly optimistic in their assumptions regarding oil prices, predicting that a decline to $65 per barrel may not materialise.
As the government grapples with these challenges, the yield on 10-year UK government bonds has surged above 5%, indicating a sharp increase in borrowing costs. Such developments raise concerns regarding the country’s fiscal stability, particularly as inflationary pressures mount.
In recent statements to the House of Commons, Reeves articulated the need for targeted support, distinguishing it from broad measures that may exacerbate inflation. She referenced the previous government’s costly untargeted support, which ultimately led to higher inflation and interest rates.
Why it Matters
The UK’s economic landscape is at a critical juncture as geopolitical tensions continue to disrupt global energy markets, with far-reaching implications for fiscal policy and household stability. The deteriorating growth forecasts signal an urgent need for decisive action from the government, as the intertwining effects of inflation and rising borrowing costs threaten to undermine economic recovery. As the nation prepares for local elections, the political ramifications of these economic forecasts may profoundly influence party dynamics and public trust in government leadership.
