Artificial intelligence promises to transform the global economy, but this does not guarantee the stability of stock market valuations. According to an analysis published on the European Central Bank (ECB) blog, a correction in US tech stock prices remains likely, even if AI fulfills its technological promises.
European Exposure to the 'Magnificent Seven'
The risk of a sharp decline on Wall Street has direct implications for the Eurozone. Data reveals a massive concentration of capital in the seven largest US tech companies (Alphabet, Amazon, Apple, Meta, Microsoft, Nvidia, and Tesla):
- Eurozone households hold a direct exposure of approximately €440 billion.
- Insurance companies and pension funds have invested an additional €440 billion.
In total, roughly €880 billion of European capital depends on the performance of the "Magnificent Seven." A significant retreat in these stocks could erode household wealth, dampen consumer confidence, and cause losses in institutional portfolios.
The Paradox of Success and Expectations
The analysis highlights a critical distinction: technological success does not necessarily equate to investment profitability. Current valuations sit well above historical averages, meaning the market has already priced in exceptionally high growth rates.
If the actual results of AI, however positive, fail to meet the "ultra-optimistic" scenario envisioned by investors, stock prices may fall. Investment psychology often drives cycles of excess, where capital inflows push prices away from fundamental economic realities.
Limited Room for Response
Unlike the dot-com collapse of the early 2000s, today's policymakers have fewer tools at their disposal. High levels of public debt and the cost of servicing it limit governments' capacity for fiscal support, while interest rates do not offer the same maneuvering room for central banks in the event of a combined crisis.
