An Integrated Financial Framework for the Banking Union: Don’t Forget Macro-Prudential Supervision

This essay reviews the sequencing of the functions of supervision, resolution, deposit insurance and the fiscal backstop in the Banking Union. All these functions deal with the soundness of individual banks. In the run-up to the 2007-2009 financial crisis, we overlooked the bigger picture of the stability of the wider financial system. This essay puts forward a concrete proposal for conducting macro-prudential policy in the prospective Banking Union. We suggest giving the lead on applying macro-prudential tools in the Banking Union to the ECB to foster a coherent approach, with important input from the national competent authorities to allow for much needed differentiation at the national level. Next, we argue that the ECB should separate the macro-prudential and micro-prudential functions. Otherwise, we may again be bogged down by the details of individual banks (micro), while losing sight of emerging imbalances in the wider financial system (macro).
