The Supply of 'Safe' Assets and Fiscal Policy

Abstract

This study looks at the interrelationship between fiscal policy and safe assets as there is surprisingly little analysis about this beyond fleeting references. The study argues that from a certain point more public debt will not “buy” more safety: countries face a kind of “safe-assets Laffer curve” with a maximum amount of safe assets at some level of indebtedness. The position and “stability” of this curve depend on a number of national and international factors, including the international risk appetite and, as a more recent factor, QE policies by central banks. The study also finds evidence of declining safe assets as reflected in government debt ratings.
