AI-enabled fraud is raising concerns about trust in financial services, and G7 finance ministers have agreed to simulate how the global system would withstand cyber-attacks. The Guardian’s Heather Stewart also reports that the UK plans to put AI safety on the agenda for its G20 presidency next year.

What happened
Stewart’s column describes warnings from IMF managing director Kristalina Georgieva that AI could make digital fraud more prolific, from fake celebrity adverts to scams targeting confidence in banks. Bank of England governor Andrew Bailey raised concerns about responsibility when AI agents act on people’s finances. The column says JPMorgan chief executive Jamie Dimon has said the bank will not let digital agents operate on customers’ behalf.
There are policy steps alongside the warnings. G7 finance ministers announced simulations to test the financial system’s resilience to cyber-attacks. The UK has pledged to take up AI safety during its G20 presidency next year. Stewart also says a US taskforce is setting up a way for AI labs to report breaches, hacks and jailbreaks, without requiring pre-launch model testing.
Why it matters
The concern is not only whether criminals can break into a bank. AI-generated scams could erode trust, while agents moving money between providers could create new questions about who is responsible when something goes wrong. These are risks officials and Stewart describe, not evidence that a wave of AI-driven financial failures has already happened.
The announced simulations offer a practical test of institutional resilience. They will not settle every question about agent liability or consumer fraud, but they are more useful than another round of solemn warnings with no exercise attached.
Our read
This is a serious policy discussion, not a forecast that financial chaos is around the corner. The useful distinction is between threats already being discussed, such as more prolific fraud, and possible knock-on effects from financial agents that regulators are still trying to understand. The simulations will matter most if their results lead to specific fixes, rather than a reassuring report that resilience was simulated successfully.
What to watch
- What the G7’s cyber-attack simulations test, and whether they lead to concrete changes.
- Whether the UK sets out what AI safety on its G20 agenda will involve.
- How regulators address responsibility when an AI agent makes or executes a financial decision.
Discussion spark: Should financial AI agents be kept out of people’s accounts until responsibility for their mistakes is clear, or would that block useful services without stopping the risks?
