Almost ten years on from the global financial crisis this thesis asks whether banks in the U.K. have learned lessons from the 2008 crisis and if these systemically important institutions are now safer. Using original empirical research including elite interviews and documentary analysis this thesis outlines how banks have responded to the institutional and structural weaknesses highlighted by the crisis to the extent that we might identify examples of learning and change. The analysis suggests that following the financial crisis different banks have taken very different paths. While some institutions have become more risk averse and display positive signs of lesson learning others have shown little evidence of change. Discussions around agency, institutional path dependency and structural competitive pressures are used to explain these inter-bank variations.
