Bank of England Governor Andrew Bailey called for international cooperation on Tuesday to address growing artificial intelligence threats, warning that the United States cannot achieve its safety ambitions alone.
Speaking before his address to financial executives at the Mansion House dinner in London, Bailey emphasized the necessity of coordinated global action.

The warning followed a temporary ban by US President Donald Trump on foreigners accessing Anthropic's Claude Mythos AI model.
Although the restriction was lifted weeks later, cybersecurity experts warned that such powerful digital tools pose potential risks to international cyber defenses.
Bailey argued that the interconnected nature of modern digital networks makes unilateral isolationism impossible for any single nation attempting to build strong cyber defenses.
"We've got to get better international understandings of how we deal with the introduction of frontier AI," Bailey said.
The governor stressed that global collaboration is essential to prevent dangerous digital tools from falling into the hands of bad actors.
"The US can't achieve what it sensibly wants to achieve, in terms of strengthening defences, on its own because it is a highly interconnected system," Bailey said.
He further elaborated on the cross-border vulnerabilities of digital systems during his formal address to financial leaders.
"No country can seal itself off from the cross-border nature of systems that are prevalent today," Bailey said.
The call for international AI standards coincided with a speech from Chancellor Rachel Reeves, who defended her economic record as she prepares to exit the Treasury.
