The ongoing conflict in Iran is projected to lead the government to seek an additional £30 billion in borrowing this year, as per expert warnings. This anticipated strain on the economy sets the stage for a challenging period ahead for Chancellor Rachel Reeves and the Labour Party.
Heightened pressure is mounting on the government to take significant financial measures to alleviate the burden of rising energy costs on both low-income households and energy-intensive businesses. Recent data from the Office for National Statistics indicates that government borrowing for the year ending in March totaled £132 billion, a decrease of almost £20 billion compared to the previous year and £700 million below the forecast by the Office for Budget Responsibility (OBR).
Elliott Jordan-Doak, senior UK economist at Pantheon Macroeconomics, cautions that any short-term benefits for Ms. Reeves may be overshadowed by a more challenging fiscal year in 2026/27. While the surge in petrol prices may bring in higher VAT revenue for the Treasury, additional revenues from windfall taxes on North Sea oil producers could be offset by an expected economic downturn due to the energy crisis.
Furthermore, businesses under strain are likely to cut jobs, potentially leading to a significant rise in UK unemployment, as warned by former Bank of England rate-setter Michael Saunders, now at Oxford Economics. These job losses could further strain the welfare budget and reduce income tax receipts.
The government is also facing increased costs for borrowing due to higher interest rates on UK government bonds. In March, debt interest payments amounted to £3.2 billion, although lower inflation at the beginning of the year helped reduce this figure by £1.3 billion compared to the previous year. However, with inflation on the rise post the Iran conflict, the debt interest bill is expected to increase.
Thomas Pugh, chief economist at RSM UK, projects that this year’s borrowing could exceed pre-war OBR forecasts by £30 billion. He suggests that as long as the surge in borrowing is temporary, there may not be an immediate need for additional tax hikes. Conversely, Lindsay James, an investment strategist at Quilter, anticipates that tax adjustments will likely be necessary to stabilize public finances, potentially impacting economic growth.
Chief Secretary to the Treasury, James Murray, emphasized that the government’s deficit has decreased by £19.8 billion due to strategic borrowing reduction efforts. Despite the challenging global landscape, Murray affirmed the government’s commitment to managing costs efficiently, enhancing energy security, and curbing borrowing and debt.
Recent fiscal changes, such as last year’s increase in employer national insurance contributions, led to a 19% surge in tax receipts to £206.8 billion, the highest since 2022/23. Debt interest costs decreased in March but rose to £97.6 billion over the full year, marking the second-highest annual level on record.
Jordan-Doak of Pantheon Macroeconomics estimates that the government’s interest payments will surpass initial projections by £12 billion this year. The evolving economic landscape post the Iran conflict necessitates careful financial planning and strategic decision-making to navigate the challenges ahead.
