At the tenth annual conference of the European Systemic Risk Board (ESRB), ECB President Christine Lagarde identified three critical areas where artificial intelligence poses systemic risks to the financial system. She noted that nearly nine out of ten significant euro area banks currently use generative AI, while seven out of ten EU securities market firms plan to increase their AI investments. Lagarde warned that as AI agents gain more autonomy, they may pursue goals in unintended ways, leading to market misalignment and potential collusion. Additionally, she highlighted that rapid advancements in AI capabilities could shorten the time between a cyber exploit and widespread automated attacks from weeks to hours, challenging traditional defense mechanisms.

The speech emphasized the concentration risk associated with reliance on a few frontier AI models, primarily developed in the United States and China. Lagarde referenced a June incident where a US export-control directive led to an abrupt suspension of access to two advanced models for European users, illustrating how geopolitical tensions can directly impact financial infrastructure. She argued that such dependencies create national security concerns, as loss of access could disrupt trading strategies and vulnerability assessments across the sector. The ESRB Advisory Scientific Committee also cautioned that widespread use of similar models might cause firms to react identically to shocks, reinforcing price movements and amplifying volatility.
