The Bank for International Settlements (BIS) warns that the global surge in artificial intelligence (AI) investment poses growing macrofinancial risks, particularly if funding conditions tighten or returns disappoint. In its annual economic report, BIS says AI-related capital flows increasingly move through “loosely regulated” non-bank channels, including hedge funds and private credit, rather than traditional bank lending. The report highlights concerns about opaque financing structures, high levels of debt, and concentrated investment tied to large AI and related infrastructure spending.

BIS also cautions that an AI downturn could trigger a fast, sharp adjustment in markets, with knock-on effects in credit conditions. Several outlets describe BIS concern that a bust could disrupt credit markets comparably to past systemic events, and could contribute to an economic slowdown.

While acknowledging that AI spending supports growth, the BIS framing emphasizes potential vulnerabilities from leverage and fast unwinds in investor and credit exposures. Separate reporting notes a parallel warning from Taiwan’s central bank chief about AI bubble risks, aligning with broader concerns about market overheating and valuation complacency.
