# Regulation B final rule on disparate impact (April 2026): Equal Credit Opportunity Act (Regulation B) — final rule amending disparate impact, discouragement and special purpose credit program provisions

Source: https://www.bankingnewsai.com/ai-regulation/documents/cfpb-regulation-b-final-rule-2026
Last updated: Aug 26, 2026

Published April 22, 2026 at 91 FR 21620 and effective July 21, 2026, the CFPB's Regulation B final rule provides that ECOA does not authorize disparate-impact liability (the 'effects test'), narrows the prohibition on 'discouragement' to statements of intent to discriminate, and restricts special purpose credit programs, including barring race, color, national origin or sex as the common characteristic. The rule was proposed November 13, 2025 and finalized as proposed. It did not amend the adverse-action notice requirements in section 1002.9.

## Key points

- Removes the effects-test language from Regulation B and its commentary; the Bureau's position is that ECOA's text authorizes only disparate-treatment claims.
- Discouragement (1002.4(b)) now covers statements expressing intent to discriminate on a prohibited basis, not statements that merely create a negative impression; encouraging statements are not discouragement.
- Special purpose credit programs: for-profit creditors face added conditions, and programs may not use race, color, national origin or sex as the common characteristic.
- Commenters argued disparate-impact liability was essential for AI-driven underwriting and algorithmic marketing; the Bureau finalized the rule anyway.
- Docket CFPB-2025-0039, RIN 3170-AB54; the proposed rule was issued November 13, 2025, with corrections published at 91 FR 9191 (Feb. 25, 2026).
- Adverse-action notice rules (1002.9) and the specific-reasons requirement are unchanged.

## What changed for banks

For AI in lending this is the most consequential CFPB action since 2022. Disparate impact was the primary legal theory under which model outcomes — not intent — could be challenged, and the basis for 'less discriminatory alternative' testing. Its removal from Regulation B shifts AI fair-lending risk toward disparate treatment (including proxy variables), HUD's Fair Housing Act rules for mortgages, state laws such as New York's and Colorado's, and private litigation over the rule's validity. Explainability obligations for adverse action are untouched.

## FAQ

### Do banks still need to test AI credit models for disparate impact after the 2026 Regulation B rule?

The CFPB no longer recognizes disparate-impact liability under ECOA as of July 21, 2026, but prudential regulators' fair-lending exams, the Fair Housing Act for mortgages, state laws and potential litigation over the rule mean most banks continue outcome testing as a risk-management practice.

### Did the 2026 rule change adverse-action notices?

No. Section 1002.9's requirement to give specific principal reasons within 30 days is unchanged and applies equally to machine-learning models.
