ECB Warns of Potential Financial Stability Risks from Excessive AI Optimism

The European Central Bank (ECB) has warned of potential financial stability risks due to excessive optimism over artificial intelligence (AI). According to a recent report, European households have approximately 440 billion euros in exposure to US technology stocks.

The ECB researchers compared the current AI enthusiasm with past technological revolutions such as the railway boom of the 19th century and the dot-com bubble. They argue that a correction in US technology stocks is likely, even if AI ultimately delivers expected productivity gains and profits.

The report suggests that investors may demand a higher risk premium as AI adoption becomes widespread, putting downward pressure on valuations. Excessive optimism can lead to prices being pushed beyond what fundamentals justify, making markets vulnerable to a sharper decline when sentiment changes.
