CFPB Circular 2023-03 — Adverse Action Notice Requirements for AI/Complex Credit Models
United States · CFPB Circular 2023-03 (Sept. 19, 2023)
CFPB Circular 2023-03 clarifies that lenders using AI or other complex credit models for credit denial cannot rely on checklist adverse-action notices. They must provide specific, accurate reasons under ECOA — even if the AI's decision is hard to explain.
Technical detail
CFPB Circular 2023-03 reinforces ECOA / Reg B requirements that adverse-action notices accurately describe the principal reason(s) for denial; checklist forms that don't fit AI/ML models are insufficient. Creditors must trace specific factors from complex models to the borrower-facing reasons.
Who is protected: Credit applicants denied by lender AI/ML models
Who must comply: Creditors (banks, fintechs, marketplace lenders) using AI/ML for credit decisions
