What did the Bank of England say about AI on 30 September 2026?

The Bank of England published three pieces on AI on the same day. The first was the record of the Financial Policy Committee’s September meeting, which opened its summary with: “Rapid advances in AI capabilities have increased cyber and operational resilience risks.”

The committee pointed to recent incidents in which frontier AI models, tested by their developers, took actions nobody intended. It said: “Recent frontier AI test-environment incidents, where autonomous models have taken unexpected actions, reinforce the FPC’s calls for firms to prepare for AI-related cyber and operational risks.” It asked firms to work with the Cross Market Operational Resilience Group, the Frontier AI Information Sharing Forum and the AI Consortium.

The second was the Systemic Risk Survey for the second half of 2026, based on 57 firms surveyed between 27 July and 24 August. Risks surrounding artificial intelligence were cited by 63% of respondents, up 32 percentage points, making AI the third most cited source of risk. The Bank wrote that “this suggests AI-related risks are becoming a mainstream concern for market participants.”

The third was an article by the Governor, Andrew Bailey, titled “Frontier AI and the question of governance”. It said: “A sensible starting point is rigorous model testing, conducted before and after deployment.” And it closed with: “The challenge before us is, therefore, not whether to embrace AI. It is how to make sure that, as these systems become more capable, society retains the capacity to govern them.”

Why does the Bank of England link AI to gilt yields and growth?

The FPC’s concern is not only operational. Its record says: “growth prospects and fiscal outlooks depend in part on expectations that AI development and adoption will generate significant productivity gains. A reassessment of those expectations could therefore affect not only AI-related asset valuations but also sovereign debt markets.”

The committee noted that “Gilt yields and US Treasury yields had reached levels not seen since 2008”. It cited a Morgan Stanley estimate of around $450 billion of global AI-related debt issuance as of early September, and said that AI hyperscaler issuance “had nevertheless accounted for 47% of GBP corporate bond issuance so far this year”.

For a financial firm in London, that is a reminder that AI shows up in two places on the risk register. One is the firm’s own use of AI. The other is its exposure to markets whose pricing now depends partly on what AI delivers. The Governor returned to the theme in Istanbul on 8 October 2026: “AI safety and financial stability are therefore becoming increasingly connected. Safely deployed, we should see AI as a growth opportunity.”

What has the government said about AI and the economy?

The government’s message in the same weeks was about adoption and skills. On 28 September 2026 the Chancellor, John Healey, confirmed £15 million a year of additional funding to restore the Union Learning Fund in England, which gov.uk describes as “helping working people gain new skills, progress at work and adapt as technology, including AI, changes the workplace.”

The same announcement said the National Wealth Fund would “create and support a further 130,000 jobs across the UK by 2030”, in sectors including AI and technology, and set out £100 million over two years for mayor-led apprenticeship services. It added: “The Budget will set out details how apprenticeship brokerage expansion and Union Learning Fund are fully funded”.

On 9 October 2026 the Prime Minister, Andy Burnham, told the Innovation Nation Summit in Manchester: “We cannot speak about innovation today without mentioning AI.” The speech also set out new powers for the Regulatory Innovation Office: “New sandboxing powers will allow us to suspend rules temporarily, giving innovators the space to test out ideas more freely.” It also promised to “ensure more UK pension capital is invested specifically in British-based, high-growth companies.”

These statements sit alongside policy already in place for the sector. HM Treasury’s Financial Services AI Adoption Plan, published on 14 July 2026, set out ten recommendations. We covered what it means for smaller firms in our Budget 2026 explainer.

What do the latest UK economic figures show?

Every figure below is the latest official release at the time of writing on 15 October 2026, with its publication date.

• Growth: monthly GDP rose 0.4% in July 2026, and 0.4% in the three months to July (ONS, 11 September 2026). GDP grew 0.5% in the second quarter (ONS, 30 September 2026). The August estimate was due on 15 October.
• Business investment rose 1.8% in the second quarter and was 5.2% above a year earlier (ONS, 30 September 2026).
• Inflation: CPI was 3.1% in the 12 months to August 2026, up from 2.9% (ONS, 16 September 2026). The September figure is due on 21 October.
• Jobs: unemployment was 4.9% in May to July 2026 and regular pay growth was 3.5% (ONS, 15 September 2026). The next release is on 20 October.
• Interest rates: Bank Rate was held at 3.75% on 17 September 2026 by six votes to three, with three members preferring 4%. The next decision is on 5 November 2026 (Bank of England).
• Public finances: borrowing was £18.3 billion in August 2026, £3.5 billion more than the OBR forecast (ONS, 22 September 2026).

Costs are the immediate pressure for many firms. In the Bank of England’s Decision Maker Panel for September 2026, published on 2 October and based on 1,993 responses, 70% of firms expected lower margins because of the energy shock.

How widely are UK businesses using AI automation?

The ONS Business Insights and Conditions Survey, published on 8 October 2026 and covering September, found that 30% of all UK businesses use at least one AI technology, up from 9% when the question was first asked in September 2023. Among businesses with 10 or more employees the figure is 38%, and among those with 250 or more it is 51%.

Among businesses with 10 or more staff that use AI, 38% said administrative and clerical roles were the most affected, and 6% reported a reduction in headcount as a result. The ONS classes these as official statistics in development.

There is an important gap for our readers. The survey does not cover finance and insurance, so there is no official ONS figure for AI use in UK financial firms. Firms should not assume they are ahead or behind. The reliable comparison is the time a workflow takes today against the time it takes after AI automation, measured on their own cases.

Investment intentions are subdued across the wider economy. The British Chambers of Commerce Quarterly Economic Survey, published on 7 October 2026 and based on more than 4,300 firms, found only 17% planned to increase investment, “a post pandemic low”. The CBI’s Financial Services Survey for the third quarter, published on 1 October, found that financial services firms “expect to increase investment in land & buildings and IT over the next twelve months”.

What does this mean for AI automation in London’s financial firms?

The Bank and the government are not pulling in opposite directions. One is saying use AI to grow, the other is saying be able to govern what you use. For a firm with 10 to 250 people, that turns into five practical steps.

1. Put AI on the risk register. List each AI tool and agent, what data it touches and who owns it. That gives the board something concrete when it asks about the Bank’s warning.
2. Test before and after go-live. Bailey’s starting point applies at any size. Run a new agent beside the existing process on live cases before switching over, and keep checking it afterwards.
3. Keep a person at every point where the work leaves the firm. Reports, returns, payments and client messages should be approved by a named person.
4. Measure against a baseline. With growth modest and margins under pressure, AI spending has to show a saving in staff time that the firm itself has recorded.
5. Report it in the MI pack. A short monthly section on AI use, incidents and results keeps senior managers informed. Our agents can prepare the numbers for MI and board packs.

What should financial firms watch before the Budget on 28 October?

• 21 October: September inflation and public finances (ONS).
• 28 October: the Budget and the OBR’s Economic and fiscal outlook, including how the skills and apprenticeship measures are funded.
• 5 November: the Bank of England’s next interest rate decision and Monetary Policy Report.
• 20 November: the closing date for the ICO’s call for evidence on agentic AI, which will inform a statutory code of practice on AI and automated decision-making.

None of these dates changes the rules for using AI in a regulated firm. The FCA’s published position is that it does not plan to introduce extra regulations for AI, and existing rules already apply to what AI does on a firm’s behalf. We look at what the recent agent incidents teach firms in our guide to AI agents for financial firms.

How can a London financial firm try AI automation without a large budget?

BraivIQ is a UK AI agency, based in London, that builds AI agents for financial firms. Every engagement starts with a 14-day Proof Run on the firm’s own exports, read-only, which times one workflow on real cases and shows every mismatch before any build begins.

Our agents prepare reconciliations, onboarding files and report checks, and a person approves every output. They never give advice, make investment or client decisions or move money. The senior team behind BraivIQ has delivered digital products for six UK banking brands.
