The Office of the Comptroller of the Currency (OCC) issued a proposal this week that would scrub references to credit ratings from its regulations, as required by the Dodd-Frank Act. In effect, the rule would end the practice of banks relying on credit ratings to determine the risk of default for underlying loans before issuing โ€œinvestment gradeโ€ securities. Instead, banks will have to makes those determinations on their own.

The agency proposed that issuers of securities backed by mortgages, student loans, and other debt,  must have an โ€œadequate capacity to meet the financial commitments under the security for the projected life of the asset or exposure.โ€
