ECB Economists Warn AI Boom May End in Correction

Five European Central Bank economists have published an analysis warning that the current AI-driven stock market boom could still end in a correction, even if investor enthusiasm proves rational and the technology delivers on expectations.

The analysis points to previous technological revolutions, including railways, electricity, radio, and the internet, where genuinely transformative technologies attracted investment and pushed company valuations higher before markets subsequently corrected.

The economists argue that it's not a matter of whether AI is successful or not, but rather how financial markets adapt as expectations about the technology align with economic reality.

Euro area investors have significant exposure to US technology equities, with an estimated £376.4 billion (€440 billion) in household exposure and considerable indirect exposure through mutual funds and exchange-traded funds.

The analysis warns that a sharp correction could prompt investors to redeem money from funds, forcing those funds to sell assets, which could push valuations lower and trigger additional redemptions.
