We investigate how bank charter value affects risk for a sample of OECD banks by using standalone and systemic risk measures before (2000-2006), during (2007-2009) and after (2010-2013) the global financial crisis. Prior to the crisis bank charter value is positively associated withrisk-taking and systemic risk for very large ―too-big-too-fail‖ banks and large U.S. and European banks but such a relationship is inverted during and after the crisis. A deeper investigation shows that such a behavior before the crisis is mostly relevant for very large banks and large banks with high growth strategies. Banks' Business models also influence this relationship. In presence of strong diversification strategies, higher charter value increases standalone risk for very large banks. Conversely, for banks following a focus strategy, higher charter value amplifies systemic risk for very large banks and both standalone and systemic risk for large U.S. and European banks.
