The bleak backdrop to John Healey’s Budget

By the Editorial Team · Monday, October 19, 2026

The IMF has raised the UK's growth forecast for 2026 and supported plans to reduce the budget deficit, driven in part by strong performance in AI-related sectors and slight GDP growth in August. However, ongoing fiscal pressures mean tax increases are likely soon, and rising interest rates could further challenge the government's efforts to balance economic expansion with deficit reduction.

Britain’s fiscal outlook remains challenging despite recent signs of economic resilience, underscoring the likelihood of tax increases in the near future. The International Monetary Fund (IMF) recently revised its UK growth forecast for 2026 upward from 1% to 1.3%, a modest but notable improvement that contrasts with the widespread expectation of worsening economic conditions. The IMF also endorsed the UK government’s plan to reduce the budget deficit, projecting a decline from 4.4% of GDP in 2025/26 to 1.6% by 2030/31, though this strategy depends heavily on future spending cuts and tax rises yet to be tested.

August’s GDP figures showed a slight 0.1% monthly increase, lower than the 0.4% growth recorded in the preceding two months, but still above economists’ expectations and suggestive of a potential 1.5% annual growth rate. Analysts attributed this resilience to several factors. First, global economies, including the UK, have adapted better than in past oil price shocks, partly due to reduced energy intensity and diversified energy sources. Second, investment in artificial intelligence (AI)-related sectors—such as computing services and infrastructure—has been a significant driver of demand growth. AI-related industries, comprising under 5% of UK GDP, contributed roughly 20% of GDP growth in the year to the second quarter and continue to support expansion.

However, these positive developments are tempered by looming financial pressures. A new round of tax increases appears inevitable, whether in the upcoming Budget or by next year. Moreover, interest rates may rise further in the United States, with the likelihood of three additional hikes, creating upward pressure on UK rates possibly as soon as the Bank of England’s November meeting. Such changes occur amid concerns over US stock market valuations and a volatile bond market, both of which could have ripple effects on the UK economy.

Upcoming economic data this week are expected to shape market reactions to the Chancellor’s Budget. Labour market figures due soon may reveal weakening employment growth and easing wage increases, while retail sales data are unlikely to prompt significant shifts. Inflation numbers, anticipated on Wednesday, are projected to jump from 3.1% in August to around 3.6% in September. With utility price increases scheduled for January and the ongoing impact of higher energy costs, inflation could rise to approximately 4.2% early next year, surpassing the Bank of England’s 2% target by a considerable margin.

Also on Wednesday, public finance figures for September are set for release. Strong nominal GDP growth may have bolstered tax revenues enough to balance increased expenditures, potentially resulting in monthly borrowing around £22 billion—consistent with Office for Budget Responsibility (OBR) forecasts. Yet, borrowing for the fiscal year remains about £8 billion above OBR expectations, highlighting the persistent scale of Britain’s fiscal challenges.

Overall, while the UK economy shows unexpected signs of vitality amid global uncertainty, the government faces a difficult path to restore fiscal stability without jeopardising growth. The Chancellor’s forthcoming Budget will be closely watched by markets for signals on how these competing priorities will be managed.
