The term standardized approach (or standardised approach) refers to a set of credit risk measurement techniques proposed under Basel II capital adequacy rules for banking institutions.
Under this approach the banks are required to use ratings from External Credit Rating Agencies to quantify required capital for credit risk. In many countries this is the only approach the regulators are planning to approve in the initial phase of Basel II Implementation.
The Basel Accord proposes to permit banks a choice between two broad methodologies for calculating their capital requirements for credit risk. The other alternative is based on internal ratings.
The summary of risk weights in standardized approach
There are some options in weighing risks for some claims, below are the summary as it might be likely to be implemented.
NOTE: For some "unrated" risk weights, banks are encouraged to use their own internal-ratings system based on Foundation IRB and Advanced IRB in Internal-Ratings Based approach with a set of formulae provided by the Basel-II accord. There exist several alternative weights for some of the following claim categories published in the original Framework text.
