IMF upgrades UK growth forecast for 2026 but warns energy prices and rates to bite in 2027

Chancellor says government will look to provide 'breathing space' for households ahead of Budget

The International Monetary Fund has upgraded its forecast for UK economic growth this year to 1.3%, up from 1% predicted in July, but warned that higher energy prices and interest rates will slow the economy in 2027 as the fallout from the US-Iran war remains 'highly uncertain'.

The UK economy is expected to expand more than previously thought in 2026 before facing a slowdown next year, the International Monetary Fund has said. In its latest World Economic Outlook, the IMF said the UK would grow by 1.3% this year, an upgrade from its July forecast of 1%. The revision comes as economies worldwide have proved more resilient to the energy price shock caused by the US-Iran conflict, though the organisation cautioned that the economic consequences of the war remain "highly uncertain".

Chancellor John Healey said the government would look to "provide some breathing space" for households in the Budget, which will be announced on 28 October. Healey is finalising the tax and spending plans for Andy Burnham's government against a backdrop of surging government borrowing costs, placing pressure on him to ensure the plans are credible with financial markets. The UK relies on these markets to borrow money.

IMF Chief Economist Silvana Tenreyro told BBC News that the UK's process of managing its debts stands out among major economies. "As you know, the UK has already started the consolidation process and it is the country that basically stands out, along with India," she said at the launch of the World Economic Outlook.

The IMF said the UK is one of the only major economies on course to stabilise levels of national debt. It projects the UK will reduce its annual borrowing by nearly four percentage points of GDP from 2025 to 2031, significantly more than the rest of the G7, many of which are increasing their deficits over that period. The UK is also projected to have the lowest annual borrowing in the G7 in 2031, and the longest maturity of debt, locking in lower rates for longer.

Analysis

Why This Matters

  • UK households face a mixed outlook: better growth in the near term but a squeeze from higher energy prices and interest rates in 2027.
  • The IMF's upgrade offers some political cover for the government ahead of its Budget, but surging borrowing costs constrain the chancellor's room for stimulus.
  • The UK's debt management strategy is being held up as an example among G7 peers, which may influence further fiscal discipline.

Background

The IMF's World Economic Outlook is a closely watched global forecast. The UK has been navigating the aftermath of the US-Iran war, which caused energy price spikes. The government, led by Prime Minister Andy Burnham and Chancellor John Healey, is preparing its first Budget amid pressure to maintain market confidence. The UK's borrowing costs have risen, testing the government's fiscal credibility.

Key Perspectives

[Chancellor and government]: Sees the upgraded growth as positive and promises household support in the Budget, but must balance spending with market expectations. [IMF]: Praises the UK's fiscal consolidation trajectory, noting it stands out among advanced economies, but warns that the conflict's economic impact remains highly uncertain. [Households and businesses]: Face immediate relief from upgraded growth but are bracing for higher energy bills and interest rates next year, which could dampen consumer spending and investment.

What to Watch

  • The Budget on 28 October for specific measures to cushion energy price rises.
  • UK borrowing costs and bond yields in the lead-up to and after the Budget.
  • Further IMF updates as the US-Iran situation evolves, which may lead to further revisions.
