ABSTRACT
Digital currencies have the potential to improve the speed and efficiency of payments and to broaden financial inclusion. The principal goal is to facilitate payments among consumers on a day-to-day basis as an alternative to cash, both domestically and across national borders. This Article begins by critically examining and critiquing the ongoing progress of trying to develop retail digital currencies, focusing on the two most feasible approaches: central bank digital currencies ("CBDC"), and privately issued currencies that are backed by assets having intrinsic value ("stablecoins"). The Article then analyzes how these digital currencies should be regulated and supervised, exploring their similarities and differences. Both CBDC and stablecoins raise innovative legal issues as well as the types of legal issues normally associated with money and payment systems, although in novel contexts. If widely used, stablecoins could also impair central banks' abilities to control monetary policy and possibly undermine confidence in the value or operational continuity of currencies, which could threaten international monetary and financial stability. Stablecoin regulation must also address those potential threats.
