Why do rating agencies monitor the issues already rated?
A rating is an opinion given on the basis of information available at a particular point of time. As time goes by, many things change, affecting the debt servicing capabilities of the issuer, one way or the other. It is, therefore, essential that as a part of their investor service, rating agencies monitor all outstanding debt issues rated by them. In the context of emerging developments, the rating agencies often put issues under credit watch and upgrade or downgrade the ratings as and when necessary. Normally, such action is taken after intensive interaction with the issuers.
