Macroprudential policies and Brexit: A welfare analysis

Author

  • Margarita Rubio

Abstract

Brexit will bring many economic and institutional consequences. Among other, Brexit will have implications on financial stability and the implementation of macroprudential policies. One immediate effect of Brexit is the fact that the United Kingdom (UK) will no longer be subject to the jurisdiction of the European Supervisory Authorities (ESAs) nor the European Systemic Risk Board (ESRB). This paper studies the welfare implications of this change of regime, both for the UK and the European Union (EU). By means of a Dynamic Stochastic General Equilibrium model (DSGE), I compare the pre-Brexit scenario with the new one, in which the UK sets macroprudential policy independently. I find that, after Brexit, the UK is better off by setting its own macroprudential policy without taking into account Europe's welfare as a whole. Given the small relative size of the UK, this implies just slight welfare loss in the EU.
