Andrew Bailey, governor of the Bank of England and chair of the Financial Stability Board (FSB), has warned G20 finance ministers and central bank governors that the most advanced “frontier” artificial intelligence models could destabilise the global economy. In a two-page letter, he said these systems are displaying increasingly sophisticated autonomy, problem-solving skills and potentially harmful capabilities.
What did Bailey tell the G20?
Bailey’s letter, sent in his role as the world’s top financial stability watchdog, flagged that frontier AI models are evolving faster than regulators can track, gaining abilities that go beyond routine automation. He described these systems as showing signs of independent decision-making and problem-solving that could carry unintended consequences if deployed across financial markets without adequate oversight.
Frontier AI models are showing increasingly sophisticated autonomy and problem-solving abilities, as well as threat capabilities, the letter warned.
Why does this matter for financial stability?
The core concern is that as banks, asset managers and other institutions increasingly rely on advanced AI tools for trading, risk assessment and decision-making, errors or unforeseen behaviour by these systems could ripple through interconnected global markets. Because AI models can act at speed and scale far beyond human capacity, a malfunction, manipulation or unexpected autonomous action could amplify shocks rather than contain them, potentially triggering a broader economic downturn.
Bailey’s intervention adds a heavyweight voice to a growing chorus of policymakers, technologists and economists who have raised alarms about AI’s systemic risks. His position atop the FSB gives the warning particular weight, since the board coordinates financial regulation among the world’s major economies and advises the G20 on emerging threats to global economic stability.
What happens next?
The letter is expected to inform discussions among G20 finance ministers and central bankers about whether existing financial regulations adequately address risks from advanced AI deployment. While no immediate regulatory measures were announced alongside the letter, Bailey’s warning signals that oversight bodies may soon need to develop coordinated frameworks specifically targeting frontier AI’s role in financial markets.
