What is CRA? The Community Reinvestment Act (CRA) is a law intended to encourage depository institutions to help meet the credit needs of the communities in which they operate, including low- and moderate-income (LMI) neighborhoods, consistent with safe and sound banking operations. (CRA does not encourage the extension of unsafe or unsound credit.)
