European Central Bank assesses euro area risks from a potential US AI stock correction

In a new blog post, the European Central Bank assesses the euro area financial stability risks from a potential correction in highly valued US technology stocks. Drawing on past technological revolutions, the authors argue that a market pullback is likely at some point regardless of whether current valuations reflect rational expectations or investor overconfidence, although its timing and scale cannot be predicted. Euro area households have about EUR 440 billion of exposure to US technology equities, largely through mutual funds and exchange-traded funds, while insurers and pension funds also have significant exposure to the Magnificent Seven stocks. Redemptions following a sharp correction could force funds to sell assets and amplify market declines. The euro area faces a lower risk of a domestically driven crash because its equity valuations and technology-sector concentration are lower, but close historical correlation with US markets means a US correction could affect euro area sentiment, financing conditions and hiring.
