The Relationship between default and economic cycle for retail portfolios across countries: identifying the drivers of economic downturn

In this article, we collect consumer delinquency data from several economic shocks in order to study the creation of stress test models. We leverage the Dual-time Dynamics modeling technique to better isolate macroeconomic impacts whenever vintage-level performance data is available. The stress test models follow a framework described here of focusing on consumer-centric macroeconomic variables so that the models are as robust as possible when predicting the impacts of future shocks. We consider the Mexican Peso Crisis / Tequila Effect by examining Argentina; Asian Economic Crisis by considering Thailand, Indonesia, and Singapore; the Hong Kong SARS recession; and the relative lack of recessions in recent data from Canada and Australia.
