Major banks including NatWest, Bank of America, ING, ASB Bank, and Capital One have released a report detailing security risks associated with AI shopping agents. The report warns that these tools, which autonomously select products and process payments, currently outpace industry standards and consumer protections.
Why it matters
The rapid growth of autonomous purchasing tools has created a disconnect between consumer financial interests and automated decision-making. Banks are now initiating discussions with policymakers to establish transparency standards and safeguards for AI agents that interact directly with cardholder data.
Data from John Lewis indicates that AI-originated search traffic reached 2.5 per cent in September 2026, representing an increase from 0.3 per cent in the same month of the previous year.
The players
NatWest
A British retail bank providing financial services and digital security oversight.
Bank of America
A multinational investment bank and financial services holding company.
John Lewis
A major UK-based retail chain tracking consumer digital traffic and search behavior.
The details
AI shopping agents function by autonomously selecting products and executing transactions on behalf of users. The report identifies specific vulnerabilities regarding how these agents handle financial information, noting that AI systems often input card details directly into third-party retail websites. Furthermore, concerns exist regarding how retailers may influence the underlying recommendations generated by AI chatbots.

The Tech Race
This report highlights a rapid acceleration in the shift of e-commerce traffic from human to AI-originated search as measured by retail metrics. The development underscores a growing competition between the rapid deployment of autonomous agents and the establishment of industry-wide financial safeguards.
Users of AI shopping assistants face potential risks related to data privacy and unauthorized access to stored card details. Consumers should remain cautious regarding how much financial information is provided to automated agents until new transparency standards are implemented.
The takeaway
The gap between AI capability and current security standards remains a primary concern for the financial industry. Readers should monitor upcoming policy discussions regarding AI transparency and consumer protection protocols for updates on future retail regulations.
