- Bank of England deputy governor Sarah Breeden questioned whether guardrails are needed "analogous to circuit breakers or kill switches" to halt market-wide trading if faulty AI models cause meltdown, speaking at the ECB's annual Sintra meeting.
- European Central Bank President Christine Lagarde warned AI poses a "major risk," telling Les Echos that model acceleration is outpacing the defense funding required to counter it.
- UK Financial Conduct Authority CEO Nikhil Rathi said the traditional rulemaking cycle "simply doesn't work" for AI moving in "weeks or months," calling for "new tools" and more collaborative oversight.
- Bank for International Settlements warned on June 28 that AI "exuberance" could trigger "disruptive macro-financial feedback loops" if central banks tighten policy to contain inflation.
- Breeden said AI-related debt financing was rising rapidly, increasing the financial stability consequences of any fall in AI asset prices.
- IMF Monetary and Capital Markets Director Tobias Adrian flagged a "potential maturity mismatch" between the duration of physical AI assets and the duration of the debt funding them.
Why it matters: The US leads in AI investment while Europe's financial system has fewer capital channels into AI than US equity markets; over-cautious European regulation could widen that gap as AI companies seek lower-compliance jurisdictions, leaving Europe exposed to systemic risks it cannot govern.
