A federal regulator said on Tuesday it is seeking input on rewriting decades-old rules aimed at encouraging bank lending in low-income communities.

The move by the Office of the Comptroller of the Currency (OCC) to seek public comment is an initial step by regulators to rewrite the 1977 Community Reinvestment Act (CRA) rules, which banks say have become outdated since they were last updated in the 1990s.

The rules are aimed at preventing discriminatory lending and so-called redlining by requiring banks to extend mortgages and other types of credit to low-income communities where they take deposits.

Regulators regularly grade banks on their compliance, and lenders that do not make the grade face limits on their ability to expand through mergers, acquisitions or adding new branches until issues are addressed.

The OCC shares responsibility for enforcing CRA rules with the Federal Deposit Insurance Corporation and Federal Reserve, which did not sign off on Tuesday’s consultation.
