Several significant ramifications for international law are evident from the standpoint of research. First, the authority and reach of international law are called into question by the growth of cross-border operations and the emergence of global players functioning outside of the official interstate system. Second, the exclusivity of international law is weakened by the growing institutionalization of this field and the emergence of private governance systems. Third, the normative authority of international law is weakened by the expanding normative influence of private entities. The organizational framework that supports international law is also reshaped because of states’ efforts to re-regulate their economic roles and support the progressive de-nationalization of institutional elements to conform to globalization. Digital currencies are reshaping and evolving our global financial systems and have sparked systematic shifts in regulation and legal discourse. This chapter looks at the evolving regulatory landscape regarding the digital currencies that exist, from cryptocurrencies and stablecoins to central bank digital currencies. The growth of this type of digital assets has also necessitated that policymakers respond comprehensively to financial stability, consumer protection, and financial crime prevention issues. The emergence of digital currencies is reshaping our financial ecosystem and the consequences of these currencies for preexisting regulatory structures become increasingly urgent for commentators, legal practitioners, and scholars to appreciate. Central bank digital currencies (CBDCs), such as China’s Digital Yuan or the European Digital Euro, are digital, legal tender national currencies that are regulated and issued by central banks, and they could fundamentally change monetary policy and payment systems.
