Stablecoins have emerged as pivotal instruments in the evolving digital financial ecosystem, promising the transactional efficiency of cryptocurrencies while mitigating their notorious price volatility. This research paper examines the legal and regulatory dimensions of stablecoins, with a comprehensive comparative analysis of approaches taken by key jurisdictions including the United States, European Union, United Kingdom, Japan, Singapore, and Hong Kong. It discusses the underlying mechanics of stablecoins, their real-world use cases, and the legal complexities surrounding their issuance, reserve management, redemption rights, and systemic risks. Through real-world and hypothetical scenarios, the paper highlights how divergent regulatory treatments affect the use and enforceability of stablecoins in cross-border transactions. The work evaluates pressing regulatory concerns such as financial stability, consumer protection, monetary sovereignty, and illicit finance, while identifying unresolved legal questions and the implications of central bank digital currencies (CBDCs) on the future of private stablecoins. The analysis concludes with a forward-looking perspective on how global regulation might shape the role of stablecoins in mainstream financial systems and international commerce.
