HSBC, Nationwide, NatWest, Barclays and Lloyds have all moved to block AI agents from customer accounts, The Telegraph reported on 8 November, including in some cases specific bans on making transactions on a customer’s behalf without their direct involvement. The newspaper said the bans are understood to be pre-emptive, with no signs yet that AI bots are accessing accounts.
By our count, that brings to 12 the financial firms in our coverage that have said or been reported to block outside AI agents since 27 October: the five big US banks, Royal Bank of Canada, Charles Schwab and these five UK lenders.
Business Pill · Agentic Commerce
An evergreen Business Engineer explainer on agentic commerce: what changes when the shopper is an AI agent. It explains the general idea only and does not discuss the banks in this story.
The key insight: HSBC, Nationwide, NatWest, Barclays and Lloyds have moved to block AI agents from customer accounts, The Telegraph reported, taking to 12 the financial firms in our coverage reported to block outside AI agents, by our count.
The Telegraph said banks are concerned that bots could “go rogue and mismanage people’s money, with no clear rules as to who would be responsible in that scenario”. Manus Costello, chief financial officer at Standard Chartered, said last week: “We need to be very careful that those tools are safe for customers and safe for us before we allow them in”.
Will Chalmers, chief financial officer of Lloyds, said the bank had not seen any sign of AI agents accessing bank accounts but added: “We do guard against that type of risk, and we take it very seriously”, according to the newspaper.
Rick Wurster, chief executive of Charles Schwab, said the company was actively blocking between 10 and 20 clients a week from using AI agents, the Telegraph reported. “We don’t want someone just giving their password to Muse, and letting Muse come in and take action on that client’s behalf”, Wurster said. “We can’t control it, the client can’t control it, something could go wrong and who’s liable?”
Financial firms reported blocking outside AI agents from customer accounts in FourWeekMBA’s coverage since 27 October 2026: five US banks (American Banker, 27 October), Royal Bank of Canada and Charles Schwab, and five UK banks (The Telegraph, 8 November). The count of 12 is FourWeekMBA’s tally, not an industry survey.
What Was Posted on X
‼️ Five of Britain’s biggest banks, from HSBC to Barclays, fear that AI agents will go rogue, so they are locking AI agents out of customer accounts.
Some have banned agents from making payments without the customer directly involved. It is unclear who pays if a bot mismanages someone’s money.
The other fear is profit. McKinsey says AI advice could move up to £700bn, about $ 900bn, out of low-paying savings accounts.
Banks fear agents acting in unison could pull deposits at once, a bank run “at machine speed.”

Intel Cyber Digest posted on X that five of Britain’s biggest banks, from HSBC to Barclays, are locking AI agents out of customer accounts, that some have banned agents from making payments without the customer directly involved, and that McKinsey says AI advice could move up to £700bn out of low-paying savings accounts. This piece takes its figures from The Telegraph’s 8 November article, not from the post.
The Money at Stake for Banks
The Telegraph also cited a McKinsey warning that savers could shift up to £700bn out of accounts that offer little or no returns and into savings products on the advice of AI chatbots. If just 5pc to 10pc of bank balances are moved this way, the profits lenders make on deposits could drop by a fifth or more, the newspaper reported.
The Financial Conduct Authority is working with the City and other regulators to develop rules to govern AI agents in finance, the newspaper said. Sources close to the regulator told it that decisions on AI access are up to the banks. In the UK, the paper noted, strict authentication rules mean most payments must be approved through a mobile banking app.
Our Count So Far
On 27 October, American Banker reported that JPMorganChase, Citi, Bank of America, Wells Fargo and Morgan Stanley were blocking external AI agents, as we reported in 5 Big Banks Block AI Agents Like Muse, BofA Puts Risk on You. That piece also cited Royal Bank of Canada and Charles Schwab blocking Meta’s Muse. The five UK names reported on 8 November take the count of financial firms to 12, by our count.
Update (9 Nov): the run-risk concern. The Telegraph’s report also said there are fears that AI agents “acting in unison could pull deposits from a bank at the same moment, triggering a run at machine speed.” It noted that Anthropic and OpenAI have launched personal-finance products that plug into people’s accounts, but that those services only read financial information rather than taking action on users’ behalf. Intel Cyber Digest’s summary of the report is embedded below.
As we read the report, the UK moves are described as pre-emptive: the Telegraph said there are no signs yet that AI bots are accessing accounts, and Lloyds’ finance chief said the bank had not seen any.
As we read the quotes, the question the banks raise is liability: Schwab’s chief executive asked “who’s liable?”, and the Telegraph wrote that there are no clear rules on who would be responsible.
As we read our count, the moves now span the US, Canada and the UK, and a marketplace outside finance, MercadoLibre, has also kept outside agents away from its inventory.

“We can’t control it, the client can’t control it, something could go wrong and who’s liable?”
Three Implications
FOR AI AGENT MAKERS The Telegraph reported that Schwab is blocking between 10 and 20 clients a week from using AI agents.
FOR UK REGULATION The Financial Conduct Authority is working with the City and other regulators on rules for AI agents in finance, the newspaper said.
FOR BANK DEPOSITS The Telegraph cited a McKinsey warning that savers could shift up to £700bn on the advice of AI chatbots.
The analysis says: “Everything downstream is a consequence of value migrating from the thing you talk to toward the thing you delegate to.”
As we read it, the banks are deciding whether the agent a customer delegates to may act inside their accounts, and for now the five UK lenders are saying no. The analysis does not discuss the banks.
What Is Not Established
The Telegraph does not quote the banks’ new terms, and we could not find the clause text on the five banks’ own websites. The report does not say when each bank made its change or which agents each one names. The count of 12 is our tally of firms named in our coverage and the reports it cites, not a survey of the industry. We did not contact the banks.
This Week In The AI Supercycle
The Great Convergence of Capital, Power, and Geopolitics
This week’s issue: for two years the AI build-out was priced as a supply story, and last week as a credit story. This week it was priced as a permission story, and the answer arrived as a cost, not a ban.
HSBC, Nationwide, NatWest, Barclays and Lloyds have moved to block AI agents from customer accounts, the Telegraph reported, joining five big US banks, Royal Bank of Canada and Charles Schwab in our count of 12 financial firms. The bans are understood to be pre-emptive, with no signs yet of bots accessing accounts, the newspaper said.
