Central banks and macroprudential policy. Some reflections from the Spanish experience

The view that central banks must play a greater role in preserving financial stability has gained considerable ground in the aftermath of the crisis and macroprudential policy has become a central pillar to deal with financial stability. The policy frame of macroprudential policy, its toolbox and interactions with other policies is not completely established yet, though. In this context, Spain’s ten-year experience with its dynamic provision is a key reference. The analysis shows that, during the current financial crisis, dynamic provisions have proved useful to mitigate —to a limited extent— the build-up of risks and, above all, to provide substantial loss absorbency capacity to the financial institutions, suggesting that it could be an important tool for other banking systems. However, it is not the macro-prudential panacea: it needs to be complemented and be consistent with the rest of policies, either within the macro-prudential or in the broader context of macroeconomic management, including monetary policy. While there is a higher awareness of the contribution of monetary policy to financial stability, its role is in practice limited. The case of the euro area is particularly telling in this respect: macro-financial imbalances developed in sectors where financial integration was low and the effects hence were confined to the domestic economies. The asymmetry between a supranational monetary policy plus macroprudential surveillance and domestic implementation of macroprudential policies raises a set of issues which are worth exploring.
