Robability Models Of Migration Hydrocyclone

Stress Testing Probability of Default and Migration Rate

Basel II implementation requires the estimations of probability of default PD and migration rate under hypothetical or historically observed stress scenarios Typically financial institutions first forecast selected macroeconomic variables under these stress scenarios and then estimate the corresponding stressed PD and migration rates These stressed parameters are in turn used in
