Application of External Ratings
Banks have the options to select credit rating agencies of their choice for both risk weighting and risk management purposes. However Banks do not have permission from RBI to “cherry pick” the assessments provided by different credit rating agencies. If a bank decides to employ the ratings of particular credit rating agencies, for a known type of claim, it can use the ratings of those credit rating agencies. Nevertheless, some of these claims may be rated by other chosen credit rating agencies whose ratings the bank has decided not to use. But banks are not permitted to use one agency’s rating for one corporate bond, and at the same time using another agency’s rating for another exposure to the same counter-party. Anyway it is allowed, when the respective exposures are rated by one of the selected credit rating agencies, whose ratings the bank has decided to use. External assessments for one entity within a corporate group cannot be used to risk weight other entities within the same group.
It is obligatory on the part of banks to disclose the names of the credit rating agencies that they use for the risk weighting of their assets. Risk Weight Mapping of Long Term Ratings of the chosen Domestic Rating Agencies are as under.
Risk Weight Mapping of Short Term Ratings of the Domestic Rating AgenciesWhere “+” or “-” notation is attached to the rating, the corresponding main rating category risk weight should be used. For example, A+ or A- would be considered to be in the A rating category.
Where “+” or “-” notation is attached to the rating, the corresponding main rating category risk weight should be used for A2 and below, unless specified otherwise. For example, A2+ or A2- would be considered to be in the A2 rating category and assigned 50 per cent risk weight.
