TL;DR
Oxford Economics says AI spending added around 0.2 percentage points to UK GDP growth last year and is set to repeat that in 2026, the Telegraph reported on 3 November. Without that boost, it puts underlying UK growth at about 1% a year. Lead economist Adam Slater warned that a reversal in AI momentum would leave the risk of recession “substantial”.
The consultancy’s concern is about dependence more than the size of the contribution. “Strip out the AI boom and the picture for the advanced economies is one of sluggish growth,” Slater told the paper. It places Britain among the largest beneficiaries of AI investment, alongside Sweden, Japan, Canada and the US.
We have read the Telegraph’s account, not the underlying Oxford Economics note, so the method behind the 0.2-point estimate is not something we can assess here.
A weak backdrop
The warning lands on an economy with little slack. According to the Telegraph, August growth was only 0.1%, and spending tied to the AI build-out helped avoid a contraction that month. It also reports that the Office for Budget Responsibility has cut next year’s growth forecast to 1%, as households and firms deal with higher fuel and energy bills from the Iran war.
Markets have supplied the trigger for the concern. The Nasdaq had its weakest month in over a year and a half in October, and Alphabet lost $500 billion in value in a single day. Deutsche Bank’s Peter Sidorov said worry had moved from chip stocks to the question of whether huge infrastructure outlays would earn “adequate returns”. Oracle fell 5% after announcing plans to raise $20 billion.
The UK’s own exposure
Much of the UK’s AI investment is physical. On the same day as this report, Drax and Brookfield announced a data centre plan that could exceed £20 billion, and the Budget’s data centre covenant is designed to speed such projects up. In our view, those projects rest on the same investor confidence now being questioned.
A contribution of 0.2 points is modest in absolute terms, but it looks larger against growth this weak.
Looking Forward
The figures to watch are quarterly investment data and whether large projects reach final investment decisions. For UK boards, the practical point is that AI now carries macroeconomic exposure as well as a technology budget line: firms planning around AI-led growth should test what happens to their assumptions if the spending slows, not only if the tools disappoint.
