UK CFOs show rising AI optimism but keep wallets closed amid economic uncertainty

UK CFOs Embrace AI Optimism as Sentiment Doubles in Two Years

AI optimism among UK CFOs has reached a striking milestone, with 73% of finance chiefs at Britain's largest companies now expressing confidence that artificial intelligence will improve business performance, according to the latest Deloitte survey 1

1

. This represents a dramatic shift from 59% at the end of 2025 and just 39% two years earlier 2

2

. The surge in confidence comes from a group not typically prone to exuberance, making the trend particularly noteworthy as the corporate case for AI moves from assumption to audit.

Deloitte polled 58 CFOs between July 1 and July 13, most from FTSE-listed companies and large private companies 1

1

. Their warming view of AI stands as one of the few metrics moving decisively upward in the quarterly survey, even as business confidence itself had sunk to a six-year low earlier in 2026 1

1

. The steady climb in sentiment matters because finance chiefs are ultimately the ones asked to demonstrate where investment dollars went and what returns materialized.

Geopolitical Risks Ease While Domestic Concerns Persist

The broader context shows an uneven thaw in corporate anxieties. Concern about geopolitical risks fell to 68 on the survey's 0-to-100 scale, down from 79 at the start of 2026 2

2

. Worry about energy prices and supply disruption eased to 60 from 70 in the first quarter, tracking the calming of tensions in the Middle East over the summer 1

. However, concerns about poor productivity and weak domestic competitiveness in the UK economy remained largely unchanged at 63 2

.

Debapratim De, Deloitte UK Chief Economist who assumed the role in June, noted that "the global economy has so far weathered the shock from the conflict in Iran better than many had feared" 2

. Yet he emphasized continuity in CFO behavior: "CFOs continue to prioritise cost reduction and cash control in this environment" 1

Cautious Spending Despite Growing Belief in AI Improving Business Performance

The enthusiasm for AI carries significant caveats when it comes to actual investment. While 96% of UK CFOs expect companies to raise technology investment over the next five years, and 77% believe that spending will lift productivity and growth, few anticipate measurable gains within the next 12 months 1

1

. This gap between conviction and near-term payoff reflects a defensive stance that favors cost reduction and cash control over expansion, even as curiosity about AI's potential grows.

Where money does flow, finance chiefs consistently favor cost-cutting AI applications that streamline operations over customer-facing initiatives that dominate marketing narratives around the technology 1

1

. Risk appetite remains subdued and well below its longer-run average, indicating that optimism has not yet translated into willingness to bet the balance sheet on AI 1

What This Means for Britain's AI Ambitions Amid Economic Uncertainty

The mismatch between belief and spending extends beyond finance departments. A BCG survey this year found most chief executives think their own boards are rushing AI transformation, suggesting the gap between boardroom appetite and operational results runs throughout the C-suite 1

1

. This matters for Britain's AI ecosystem, where startups are now valued at roughly $256bn 1

1

. CFOs warming to the technology provides demand-side support for that supply-side ambition, though the translation to actual spending remains incomplete.

The direction aligns with what McKinsey recently concluded: the productivity payoff from AI is real but conditional 1

1

. Research showing that time freed up by AI is often quietly wasted helps explain why belief and measurable return remain separate items on the ledger. Whether the 73% optimism figure represents a ceiling or a staging post will become clearer in Deloitte's next quarterly reading. For now, the people who sign the cheques are more willing to believe in AI than to spend as though they already do.
