TITULIZACIóN HIPOTECARIA EN ESPA A: UNHA ANáLISE DO RISCO PARA AS ENTIDADES ORIXINADORAS

This paper examines the systemic risk reaction of banks' stocks negotiated in the Spanish stock market to Mortgage Backed Securities. We use an event study methodology for securitization registration and issue dates from 1993 to 2010. The paper provides empirical evi-dence that securitization has a positive impact on the increase of Spanish bank's systematic risk on the days following the registration and issue dates.
