Central bankers demand AI kill switches to curb market volatility

Bank of England Deputy Governor Sarah Breeden proposed implementing mechanisms akin to market circuit breakers or emergency kill switches to force a halt on trading if faulty AI models cause systemic disruption. These concerns reflect a growing consensus among policymakers that traditional, multi-year rulemaking cycles are incompatible with technology that shifts in mere weeks.

Financial stability risks are compounded by the way AI development is being funded. Tobias Adrian of the International Monetary Fund highlighted a dangerous mismatch between the long-term capital requirements of physical AI infrastructure and the short-term maturity of the debt used to finance it. This structural fragility, paired with a potential correction in AI-related asset prices, remains a primary focus for the Bank for International Settlements, which warned of significant macro-financial dangers in its June 28 report.

Christine Lagarde, President of the European Central Bank, noted that the speed of AI advancement now dwarfs traditional cybersecurity threats, leaving regulatory defenses perpetually in catch-up mode. Meanwhile, UK Financial Conduct Authority Chief Executive Nikhil Rathi emphasized that regulators must pivot toward agile, industry-cooperative approaches rather than relying on standard, slow-moving legislative processes. The urgency is further underscored by geopolitical tensions, as Austria recently urged the European Union to secure independent access to frontier models following U.S. export restrictions on companies like Anthropic.
