BIS Warns AI Investment Bubble Could Trigger Global Recession

The Bank for International Settlements warned in its June 2026 annual economic report that an investment bubble in artificial intelligence could trigger a global financial crisis and economy-wide recessions. The institution noted that five major US hyperscalers, including Microsoft, Meta, and Amazon, are projected to spend over $1 trillion on AI infrastructure across 2025 and 2026, with capital expenditures currently outpacing earnings and free cash flow.

Comparing the current trend to historical manias like the dot-com boom and 1830s canal mania, the BIS cautioned that a failure to deliver productivity payoffs could lead to a protracted investment bust. The report identified systemic risks stemming from high leverage and debt-heavy nonbank structures, which could cause cascading defaults if investor optimism fades or central banks tighten policy to fight inflation.

Beyond financial volatility, the BIS highlighted labor displacement risks as AI competes directly with human cognitive abilities. Supply-side bottlenecks in semiconductors and electricity are already impacting consumers, contributing to inflationary pressures. These factors, combined with record-high public debt and a "sovereign-financial stability nexus," leave the global economy vulnerable to sharp drops in sovereign bond values.

General Manager Pablo Hernández de Cos emphasized that while a recent ceasefire between the U.S. and Iran helped avoid extreme scenarios regarding the Strait of Hormuz, policymakers must urgently reduce debt and prioritize price stability to avoid costly future adjustments.
