By using the spatial econometrics methodology, this paper investigates the contagion of the risk taking by banks in the US banking sector during 2001 to 2012. In addition, the contagion signals up to the Subprime crisis in 2008 are analyzed and different channels of contagion are studied in order to identify fragile groups of banks. Our analysis reveals that there is no significant contagion transmitted to the whole banking system. However, we observe that the bank contagion is significantly spread locally and for the group of banks that share similar characteristics related to size and bank regulations.
