Barclays is among five major UK lenders that have moved to block or restrict outside artificial-intelligence agents from customer accounts, according to a Yahoo Finance report published on Sunday, November 8. HSBC, Nationwide, NatWest and Lloyds were also named.
Some of the restrictions specifically prevent an agent from making transactions on a customer's behalf without the customer directly approving the action. The report said the banks are acting before a confirmed wave of automated account activity, rather than responding to identified losses or a known breach.
Account access remains the key issue
The concern is that personal finance bots could act unexpectedly, mismanage money or make unsuitable payments. Responsibility would also be difficult to establish if an autonomous agent made a mistake while operating inside a customer's account.
Lloyds chief financial officer Will Chalmers said the bank had not seen signs of AI agents accessing accounts, while adding that it was guarding against the risk. The Financial Conduct Authority is working with the financial sector and other regulators on rules for AI agents in finance. Until a common framework emerges, individual lenders are deciding how much access to permit.
The debate extends beyond security. The report cited the possibility that large numbers of customers could use AI tools to move deposits toward better-paying savings products at the same time. McKinsey has warned that savers could shift up to 700 billion pounds from low-yield accounts, while a movement of 5% to 10% of bank balances could reduce banks' deposit profits by a fifth or more. These estimates describe a potential industry risk, not a forecast for Barclays.
What the move means for Barclays
For Barclays, tighter access rules may reduce near-term risks from unauthorized or poorly controlled automated activity. They could also slow the bank's participation in a developing distribution channel if customers increasingly expect personal AI assistants to compare products, manage savings or initiate payments.
UK payment authentication rules already require most payments to be approved in a mobile banking application, often with a fingerprint or face scan. That keeps a customer involved at the final stage, although the exact effect of the new restrictions depends on the wording of each lender's account terms and on future regulation.
