Artificial intelligence is rapidly becoming part of modern finance, from hedge funds and trading firms to retail investment apps used by ordinary investors. But a new study by researchers from the European Central Bank, Stanford University, Deutsche Bundesbank, Stanford HAI, the Centre for Economic Policy Research, and the University of Naples Federico II warns that AI could also create new threats to financial stability.
The study examines how AI systems behave during moments of financial stress. The researchers argue that the future stability of markets may depend not only on economic conditions, but also on the specific type of AI making investment decisions.
Their central finding is simple but striking: different AI systems react to financial uncertainty in completely different ways, and some may actually increase the risk of panic-driven market behaviour.
Two Types of AI, Two Very Different Behaviours
The researchers tested two major kinds of AI investors in a simulated financial market.
The first type was Q-learning algorithms, a form of reinforcement learning already used widely in algorithmic trading. These systems learn through trial and error, adjusting their behaviour based on rewards and losses over time.
The second type was large language models, or LLMs, similar to the AI systems powering advanced chatbots and reasoning tools today. Unlike Q-learning systems, LLMs do not slowly learn through repeated experience. Instead, they analyze situations and make decisions using reasoning and context.
The researchers placed both AI systems inside a classic “mutual fund redemption” model. In this setup, investors must decide whether to keep their money invested or withdraw it early. Their decisions depend not only on economic fundamentals, but also on what they believe other investors will do.
The framework mirrors the logic behind bank runs, market panics, and even modern stablecoin collapses.
