This note outlines a concrete proposal for a euro area CFC that could help smooth both country-specific and common shocks. Specifically, it proposes a macroeconomic stabilization fund financed by annual contributions from countries used to build up assets in good times and make transfers to countries in bad times, as well as a borrowing capacity in case large or persistent shocks exhaust the fund’s assets. The note also discusses several features aimed at avoiding permanent transfers between countries and making the CFC function as automatically as possible—to limit the scope for disputes over its operation—both of which are important points to make it politically acceptable.
