Bank of England flags stretched AI valuations, AI debt and circular financing

See how this story connects

The Bank of England’s July 2026 Financial Stability Report said AI equity valuations were more stretched and AI firms now make up around half of the S&P 500 by value, while hyperscalers took over 15% of year-to-date US investment-grade issuance and AI issuers 41% of non-refinancing US high-yield issuance. It explicitly flagged circular financing, where tech firms invest in AI companies that then buy their products, plus off-balance-sheet data-centre vehicles; a modelled 45% US equity fall cut UK GDP by 2.2 percentage points.

Why it matters

The Bank of England named circular financing and off-balance-sheet data-centre vehicles as risks, and modelled a 45% US equity fall cutting UK GDP by 2.2 percentage points.
