Abstract

The paper explores the precarious balance between modernizing monetary systems by means of digital
currencies (either issued by the central bank itself or independently) and safeguarding financial stability
as also ensured by tangible payment (and saving) instruments like paper money. Which aspects of modern payments systems could contribute to improve the way of functioning of today’s globalized economy? And, which might even threaten the above mentioned instable equilibrium? This survey-paper aims, precisely, at giving some preliminary answers to a complex – therefore, ongoing – debate at the scientific as well as the banking and the political level.
