UK banks push agentic AI toward customers, raising new consumer risks

Gillian Tett

The rapid push by banks toward agentic artificial intelligence marks a qualitative shift in financial services that goes well beyond familiar chatbots and analytical tools. At YourDailyAnalysis, we view this transition as the start of a new phase of digitalization in which the central challenge is no longer algorithmic capability, but the governance of autonomous systems capable of making and executing financial decisions on their own.

The defining feature of agentic AI is its ability to act, not merely to recommend. This fundamentally changes the risk profile for retail customers. An error in a generative system may result in incorrect advice; an error in an agentic system can trigger a sequence of financial transactions executed at speed and without timely human intervention. In our assessment, it is this combination of autonomy and velocity that underpins growing regulatory concern.

Early pilot programs in the UK banking sector indicate a deliberate move toward deploying agentic AI not only in internal operations, but also in customer-facing products. Analysts at YourDailyAnalysis note that this elevates the importance of trust architecture: transparent decision logic, explicit customer consent, and the ability to instantly suspend automated actions. Without these safeguards, even value-adding use cases – such as automated savings allocation or personalized budgeting – risk eroding confidence rather than enhancing it.

The UK regulatory framework stands out relative to other jurisdictions. Structured testing environments and phased deployment models lower the barrier between experimentation and production. We believe this regulatory flexibility helps explain why British banks are advancing more quickly than many of their European peers in consumer-oriented agentic AI applications.

Risks, however, extend beyond individual users. Systemic vulnerability arises not from the failure of a single agent, but from the synchronized behavior of many autonomous systems responding to the same signals. At Your Daily Analysis, we view scenarios involving mass fund transfers, automated deposit reallocations, or simultaneous investment actions as potential amplifiers of volatility and liquidity stress, particularly during periods of market instability.

Reliability remains another constraint. Agentic AI systems are still prone to flawed reasoning and contextual misinterpretation, especially in complex advisory settings. We believe the most dangerous outcomes in financial services are not obvious malfunctions, but persuasive yet incorrect decisions that appear rational and are therefore harder to detect and challenge.

The economics of deployment also remain uncertain. Despite strong interest, a significant share of agentic AI projects may fail to scale. Infrastructure costs, deep integration with core banking systems, and expanding compliance requirements raise the threshold for commercial viability. At YourDailyAnalysis, we expect a period of natural selection in which only solutions demonstrating clear operational and economic value will persist.

Our conclusion is that 2026 will represent a transition year for agentic AI in retail banking. Initial large-scale deployments are likely to coincide with tighter regulatory oversight and more demanding risk-management standards. Ultimately, success will favor institutions that embed agentic AI within transparent, controllable and reversible decision frameworks. For the industry, this is less a race to automate than a competition to establish trust, accountability and resilience.
