This paper deals with credit risk in the Uruguayan aggregate economy andtherefore correspond to financial stability purposes. To analyze the risk associ-ated with a portfolio of loans a nonlinear parametric model based on Merton’sapproach is used, in which a default event occurs if the returns of the economicagent falls below a certain threshold that depends on macroeconomic variables. The estimated models can help to understand the relationship between creditrisk and macroeconomic indicators. The results obtained can be consideredfor estimating the credit risk module in the stress tests framework of the localbanking system. ”Elasticities” of impact of the relevant macroeconomic factoron credit risk are reported for corporate and households lending, both in localcurrency and dollars. The parameters are obtained by the statistical technique ofMaximum Likelihood, where the function to maximize contains a latent randomfactor that is assumed to have normal distribution.
