IMF nudges up UK 2025 growth outlook, sees more inflation

British finance minister Rachel Reeves and Bank of England Governor Andrew Bailey will attend annual IMF meetings in Washington this week, where participants will discuss how the world is adjusting to President Donald Trump’s new tariffs.
The IMF predicts the UK economy will grow at an annual rate of 1.3 per cent this year and next; An upward revision of 0.1 percentage point for 2025 and a downward revision of 0.1 percentage point for 2026 compared to the last forecast in July.
The Bank of England also published a similar forecast in August.
“This is the second consecutive upgrade to the IMF’s growth forecast for this year,” Reeves said in response to Tuesday’s change. he said. “But I know this is just the beginning. For a lot of people, our economy seems stuck.”
The IMF’s forecast for the UK comes alongside a broader update to its global forecasts; These estimates generally show slightly less impact on advanced economies than the initially feared impact from the highest U.S. tariffs in a century. Britain’s growth rate is the second fastest in the Group of Seven Advanced Economies this year and the third fastest in 2026, behind the US and Canada. The IMF said the upward revision to Britain’s 2025 growth reflected strong growth in the first half of the year. But overall growth in 2025 and 2026 is still estimated to be 0.4 percentage points below the figure the IMF predicted in October 2024, before Trump was elected.
Much of Britain’s economic growth also reflects historically high levels of immigration.
On a per capita basis (a better indicator of average living standards) the IMF predicts Britain’s gross domestic product will rise by 0.4% this year and 0.5% in 2026. Although the latter is the weakest estimate in the G7, it is close to Britain’s historical average in the decade leading up to the 2016 Brexit referendum.
The IMF said consumer price inflation is forecast to average 3.4% this year and 2.5% next year, the highest level in the G7 and an upward revision since its April forecast.
High inflation is limiting the BoE’s ability to cut interest rates and contributing to the new government borrowing cost being the highest in the G7.
The IMF said higher inflation partly reflected one-off increases in regulated prices and was “expected to be temporary, with labor market easing and moderate wage growth eventually helping inflation return to target by the end of 2026 – several months earlier than the BoE expected.”
The IMF predicts that the UK unemployment rate will remain at 4.7% this year and next, the current four-year high.
