European Central Bank President Christine Lagarde warned Wednesday that artificial intelligence could trigger dangerous financial crises and urged global governance modeled on Cold War nuclea
European Central Bank President Christine Lagarde warned Wednesday that artificial intelligence could trigger dangerous financial crises and urged global governance modeled on Cold War nuclear treaties.
- Lagarde said AI could trigger financial crises more damaging than past technology-driven job losses.
- She urged worldwide AI governance resembling Cold War nuclear non-proliferation treaties.
- The ECB stress-tested 109 banks against a severe AI-powered cyberattack scenario.
The remarks came during a speech in Venice, the bluntest warning yet from a central bank chief on AI and financial stability. Lagarde said the deeper danger is not the technology itself but the market turmoil it could unleash across the economy. As these systems grow more powerful, she added, they keep pushing further into finance and into everyday economic life.
She framed crises, not machines, as the force that has stripped more from jobs and savings than any technology before it. The ECB has already subjected 109 banks to a severe AI-driven cyberattack scenario, and most of the weaknesses it exposed have since been addressed, the central bank said.
Lagarde said she will write to bank chief executives, urging them to treat resilience as serious spending rather than a box to tick. She warned that AI could reshape the financial sector from within, creating fresh concentrations of risk and new openings for those who would do harm. Even sound regulation, she conceded, cannot hold the technology back.

The non-proliferation comparison is rare for a sitting ECB president, borrowed from treaties that held because rival powers accepted shared limits. "We cannot stop artificial intelligence, even with our sound regulations," she said.
Her appeal follows a sharper alarm from International Monetary Fund chief Kristalina Georgieva, who spoke in Brussels last week. She warned that advanced models like Anthropic's Mythos could be turned against the financial system, and called the technology "just the beginning."
Regulators have flagged that such tools can find and exploit flaws across major operating systems and browsers, even when handled by non-experts.
The IMF has concluded that AI can help attackers breach defenses faster than banks can patch them, and it has flagged the absence of any global cybersecurity authority to coordinate a response. Lagarde made a parallel case, calling for a European capital markets union and tighter oversight of a technology that ignores borders.
For months the ECB has pushed eurozone lenders toward tougher cyber defenses, with the Financial Stability Board urging similar safeguards. In May the IMF warned that extreme cyber losses could strain bank funding, raise solvency concerns, and disrupt trading across the wider market. Venice marked the moment Lagarde lifted that worry from the cyber desk into the core of monetary policy.
