Default is nothing more than a particular, albeit extreme, example of a rating migration, and upgrade, the calculated credit risk in migration mode is for the pricing of credit derivatives as well as credit risk management.

This causes changes to their Credit aluationV Adjustment (CVA), which is the market avlue of counterparty credit risk. The higher counterparty credit risk, the more the protection against default of that counterparty should cost, e.g. in form of a credit default swap. by risk rating. KPMG’s Sixth Annual Survey of Bank Credit Risk Management Practices revealed that 51% of all bank respondents use migration analysis. Of those banks with assets greater than $10 billion, 70% report using migration analysis.

The bond rating is an important indicator to evaluate a company’s credit quality, as well as their default probability. Simulate Credit Rating Migration Risk. Simulate credit portfolio value changes due to credit rating migrations using copulas. The creditMigrationCopula object 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.
