The CAMELS rating is assigned by government regulators on a scale of 1 to 5, with 1 and 2 being assigned to financial institutions that are in the best fundamental condition. A rating of 4 or 5 often indicates serious problems that require immediat action or careful monitoring. A rating of 5 is given to an institution that has a high probability of failure within the next 12 months.
The CAMELS rating is never relased to the public, and is kept confidential. For this reason, the private bank-rating companies use proprietary formulas in an attempt to replicate it. Because no rating service is identical, investors and clients should consult multiple ratings when analyzing their financial institution.
