BoE Governor Bailey: More Pre- and Post-Deployment Testing Needed for AI Models Before Regulation

Bailey's framing puts testing ahead of rulemaking, effectively making the central bank's regulatory timetable contingent on evidence that doesn't yet exist. That matters for AI developers and financial firms eyeing deployment in UK markets, since it implies supervision will follow demonstrated safety rather than fixed deadlines. The open question is whether this pre- and post-deployment testing becomes a de facto gatekeeping standard, and who ends up defining what counts as sufficient.
