Digital Finance and Regulatory Competition is a book addressing the question of whether the worlds leading financial centres Hong Kong, London, and New York engaged in regulatory competition with one another through their formulation of the rules to govern distributed ledger technology (DLT)-based financial products and services in their respective jurisdictions during the period 2008-2022. In light of this, the book furnishes a clear and cohesive framework to understand the influence of regulatory competition in the worlds major financial centres, utilising a narrative lens built on a comparative study of legal, regulatory, and policy instruments. The outcome is an exhaustive and thought-provoking analysis which distils observations regarding the regulation of DLT-based financial products and services and the potential implications for the future regulation of other novel technologies in the financial services industry.
