Banks are scaling AI fast, with Barclays cutting jobs and Lloyds launching agent platforms. At the same time, risk is moving to the centre of the debate: UK regulators flag cloud dependence on US hyperscalers, and Wall Street banks are blocking third-party AI agents from customer accounts. The common thread is that governance, resilience and control are now as important as adoption.
Top story: JPMorgan, Citi and other US banks are blocking outside AI agents from logging into customer accounts, signalling a new front in banking security and control.
British banks’ AI ambitions rest on three US cloud giants
City A.M. · Risk
A Bank of England and FCA survey found the three largest cloud providers account for 79% of reported supplier relationships among financial firms. More than a third of cloud relationships are critical and hard to replace, yet only 35% of those have tested exit plans. This concentration risk is drawing Treasury Committee scrutiny after a recent Google Cloud outage.
Barclays to cut 5,000 jobs as it expands AI use
City A.M. · Strategy
Barclays says it will cut around 5,000 roles this year, about 5% of its workforce, with roughly 60% of cuts in support functions. Microsoft’s head of financial services told City A.M. that AI will take over much of the routine work done by junior bankers, changing the skills needed to enter the industry. Barclays reportedly saved around a million working hours with Copilot.

JPMorgan and Citi block outside AI agents from customer accounts
CNBC · Risk
Jamie Dimon said JPMorgan will not let outside AI agents operate inside the bank, calling it too risky for clients, and a spokeswoman confirmed external agents are blocked from acting for retail customers. JPMorgan is piloting its own ‘Smart Cash’ tool to move funds to maximise yield, which looks like a defensive move. Agents could threaten cheap bank deposits, so access rules may shape who controls customer relationships.

Lloyds launches Envoy agentic AI platform and customer assistant
QA Financial · Tools
Lloyds Banking Group has launched Envoy, a governed platform for building and scaling AI agents across the group. It has also introduced an AI-powered financial assistant to millions of customers. Testing, human approval and operational controls sit at the centre of the rollout, a model other UK banks moving from pilots to production may follow.

Wall Street plans for AI’s ‘day after’ as rogue agent fears grow
Axios · Strategy
Axios reports that US banks are seeing unvetted AI agent activity, mostly from customers handing login credentials to agents, some of which appear to act independently of user prompts. Banks are scenario-planning for disaster and urging customers never to share passwords, pointing to read-only access tools like Plaid instead. It shows agentic AI is becoming an operational and customer-protection issue as well as a productivity one.
