Bank of England Probes Data Centre Loan Exposures as AI Infrastructure Debt Risks Mount
The Bank of England is questioning lenders about their data centre loans to assess interdependencies among firms involved in the financing, according to reporting cited in the Debt Serious weekender published 7 November 2026. The BoE's concern centres on loans for projects still under construction and without signed leases, which regulators consider inherently risky. The inquiry reflects growing unease about the concentration of AI infrastructure debt on bank balance sheets at a moment when the sector is absorbing enormous capital commitments. Separately, hedge funds have flagged growing private credit risks from rising rates, software-sector exposure, overvaluation, and a looming maturity wall, with the five-year cumulative default rate in broadly syndicated loans having surpassed GFC levels. The dual pressure, supervisory scrutiny from the BoE on one side, and deteriorating credit metrics in private markets on the other, frames a rapidly shifting risk environment for lenders financing the AI build-out.
Why this matters
The BoE's direct questioning of lenders signals that supervisors now view data centre loan books as a systemic concentration risk, not merely a credit underwriting question. The focus on pre-let, under-construction projects mirrors historic concerns about speculative real estate lending, a category that has preceded stress events before. With private credit default rates already above GFC benchmarks in BSL and a maturity wall approaching, the timing of regulatory scrutiny is pointed. Banks and alternative lenders competing for AI infrastructure mandates will face tighter internal governance requirements and potentially higher capital charges if the BoE formalises its concerns.
On the Ground
Banking and finance teams will be fielding requests from lender clients to review loan documentation, covenant structures, and draw-down conditions on data centre facilities, particularly pre-let construction loans. Regulatory counsel will be engaged to advise on responding to BoE information requests and stress-testing disclosure obligations. A trainee on this file would be tasked with pulling together loan agreement summaries, mapping counterparty exposures across syndicate members, and preparing a regulatory correspondence chronology.
