The Credit Transition Model (CTM) is Moody’s proprietary issuer -level model of rating transitions and default. It provides projections of probabilities of rating transitions and default for over 7000 bond and loan issuers. probability of default. Credit ratings are set by rating agencies such as Standard and Poor's or Moody's, but larger banks and nancial companies often have their own internal rating system used on its counterparties. In particular, rating migrations will be estimated using a Markov chain framework, where migra- Table I Measured Spread From Treasury This table reports the average spread from treasuries for AA, A, and BBB bonds in the financial and industrial sectors. For each column, spot rates were derived using standard Gauss-Newton non-linear least squared methods as described in the text. Treasuries are reported as annualized spot rates. Corporates are Over each time span, lower ratings correspond to higher default rates (see chart 4 and chart 25), and this relationship holds true when broken out by rating category and by rating modifier (see tables 24 and 26), as well as by region (see table 25). As the Gini ratios show, the ability of corporate ratings to serve as effective measures of relative The creditMigrationCopula takes as input a portfolio of credit-sensitive positions with a set of counterparties and performs a copula-based, multifactor simulation of credit rating migrations. Counterparty credit rating migrations and subsequent changes in portfolio value are calculated for each scenario and several risk measurements are reported. ratings across the globe.

Credit Rating Migration Risk. The migration-based multi-factor copula (creditMigrationCopula) is similar to the creditDefaultCopula object. As described in Credit Simulation Using Copulas, each counterparty’s credit quality is represented by a “latent variable” which is simulated over many scenarios. The latent variable is composed of a series of correlated factors which are weighted based on the counterparty’s sensitivity to each factor.
