Recently, the seemingly unstoppable march of AI deployment across the world economy has rarely been out of the news. As financial services firms increasingly adopt AI-driven tools within their businesses, a key question has been how regulators will respond and whether they have clearly articulated their expectations for AI usage and governance across the sector.
Earlier today (19 October 2026), the UK Financial Conduct Authority (FCA) published a speech by its Chief Data, Information and Intelligence Officer, Jessica Rusu, on the FCA's approach to AI adoption within the financial services industry. This was accompanied by the launch of a new FCA publication on good practices and areas for improvement in relation to AI in financial services. The speech and guidance document are partly a response to the earlier Mills Review on AI and the future of retail financial services, published in July 2026.
For firms that have been following the FCA's public discussions until now around the risks and benefits of AI usage, the content of Ms Rusu's speech and the new guidance document are unlikely to come as a surprise. They both largely reinforce, rather than revolutionise, the FCA's existing approach, but they are indicative of the increasing importance of this issue to the regulator.
We have set out some of the key points from the speech and the guidance document below, although firms should ensure that they read the guidance in full and consider the FCA's expectations in light of their current AI usage.
KEY ACTION POINTS FOR FIRMS
- The FCA guidance is clear that it does not create new regulatory expectations and that firms should assess what is appropriate and proportionate in light of their own AI deployment and the associated risks in their business. As a result, not every observation in the FCA guidance will be relevant to every type of firm.
- The formalisation of FCA expectations in the guidance is a strong indication that AI governance and risks are rising up the regulator's supervisory agenda. Firms should therefore review their existing AI policies and procedures (both their general policies and those governing more specific areas, such as the use of AI-driven recording and transcription tools) against the guidance and ensure that they would be able clearly to articulate their approach to governance, operational resilience and ensuring good outcomes in connection with AI if they were asked.
- Firms should clearly map their usage of AI within their businesses, as well as their potential wider exposure to AI models (for example, through third-party service providers who may themselves be dependent on AI tools). The firm's assessment of what is appropriate and proportionate for its business model will need to be underpinned by a solid understanding of the applicable AI touchpoints.
- Where a firm's deployment of AI models is at an early stage of sophistication, with limited AI autonomy and more extensive human involvement, the firm may be able to conclude that the usage is relatively low risk and some elements of the guidance are therefore less relevant. Conversely, as AI usage becomes more embedded with increasing business dependencies and greater autonomy for the AI model, the regulator's expectations are likely to increase.
- Demonstrating clear oversight and accountability will be key. This can be structured in different ways according to the structure of the firm's business and the way in which AI has been deployed, but the FCA will expect the firm to be able to explain who has day-to-day oversight of AI models and who has ultimate accountability for deployment and the firm's overall AI strategy.
- Given the increasing risks of cyber-attacks as frontier AI models become ever more advanced, the FCA recommends that firms should consider cyber insurance. Firms may therefore wish to review existing insurance policies or to explore whether appropriate insurance is available at an affordable cost.
