A World Overleveraged on Optimism? Report Questions AI-Fueled Market Rally

A new global economic report is questioning whether the world is overleveraged on optimism, particularly regarding artificial intelligence. It warns that “stretched valuations” in the stock market pose a major risk to an otherwise resilient economy, suggesting the current rally may be built on a fragile foundation of hype.
The analysis, which comes from a preeminent financial institution, highlights that AI-related spending has been a “significant contributor to investment growth recently.” However, it cautions that if markets reassess the technology’s short-term profitability, the resulting “correction” in share prices could trigger a “rather sharp” decline in the aggregate investment that has been propping up the economy.
This warning about a potential tech bubble is a key reason for the report’s “dim” long-term outlook, a pessimism that exists despite an upgrade to this year’s global growth forecast to 3.2%. The institution clearly sees a dangerous disconnect between market sentiment and the real economic challenges ahead.
These challenges include the still-to-be-felt impact of US trade tariffs, which are expected to depress business investment over the medium term. The report also flags the economic damage from restrictive immigration policies as another headwind that financial markets seem to be ignoring.
For countries like the UK, which faces its own battle with G7-leading inflation, a global market downturn sparked by a loss of faith in AI would be a significant blow. It would complicate an already difficult policy environment and underscore the report’s central theme: the current optimism is dangerously mismatched with the underlying risks.
