ECB President Lagarde Warns AI Could Amplify Financial System Vulnerabilities

ECB President Christine Lagarde has warned that the greatest risk posed by artificial intelligence in the financial sector is not the technology itself, but its potential to exacerbate systemic vulnerabilities. Currently, the European Central Bank has completed targeted reviews of AI and cybersecurity at 109 banks and will send letters to their chief executives urging stronger risk defense capabilities. Lagarde also called for the establishment of a globally coordinated regulatory framework for AI to prevent the misuse of technology from triggering a systemic financial crisis.
As AI permeates the financial system at an unprecedented pace, regulators are concerned that the seeds of the next financial crisis may already be silently embedded in algorithms and models.

Speaking in Venice on Wednesday, Lagarde cautioned that the greatest risk of this technological revolution is not the technology itself, but its capacity to amplify the fragility of the financial system, potentially culminating in a new financial crisis.

She noted that the development of AI is irreversible, and the core task of regulators is to ensure that the public benefits from technological dividends while being shielded from potential risks. As AI systems continue to grow in capability, their influence is rapidly spreading into the economic and financial spheres, with financial stability set to become one of the most formidable challenges ahead. She stated: “In modern history, the forces that have destroyed the most jobs and erased the most savings are not technology, but financial crises.”

AI is reshaping the financial system, and Lagarde has highlighted new focal points of risk. In recent years, the application of AI in the financial industry has expanded rapidly, penetrating areas such as risk management, trade execution, and customer service, covering nearly all aspects of banking and financial institution operations.

However, Lagarde pointed out that the real concern lies in the emergence of new risk concentration points as more institutions rely on similar models, algorithms, and data sources. In the event of system misjudgment, attacks, or herd behavior, the impact could far exceed that of traditional financial risk events.

She emphasized that AI is reshaping the financial system from within, not only creating new channels for risk accumulation but also opening new attack vectors for malicious actors. Unlike previous technological revolutions such as the internet and mobile communications, AI’s impact is not limited to increased production efficiency but may directly influence the operational mechanisms and risk transmission pathways of financial markets.

To identify potential risks early, the ECB has incorporated AI-related risks into its bank regulatory framework. Lagarde revealed that the ECB has conducted specialized reviews of 109 banks, focusing on assessing their capacity to respond to cyberattacks and AI-related risks.
At present, most of the identified issues have been rectified, but regulatory efforts are far from over.

Next, the European Central Bank (ECB) will send formal letters to chief executive officers of major banks, urging them to further enhance their awareness and response capabilities regarding AI risks, and to prepare for sustained investment. Lagarde emphasized that building defense systems against AI attacks, improving data security, and strengthening operational resilience all require substantial resource and capital allocation from banks.

At the European level, Lagarde called for accelerating the integration of capital markets while strengthening regulatory coordination to enhance the overall resilience of the financial system against technological shocks. She stated that ensuring this technological revolution does not evolve into a financial crisis is one of the most important ways the European Central Bank serves the people of Europe.

On this basis, Lagarde further elevated AI risk governance to a central position on the global agenda. She pointed out that the development of artificial intelligence inherently transcends national borders, and regulatory measures by a single country or region alone are insufficient to effectively contain risks. The international community urgently needs to establish a globally coordinated regulatory framework to achieve cross-border governance of AI.
