Cryptocurrency and Financial Crime: Opportunities and Challenges for Regulation

Abstract

Abstract The rapid growth of cryptocurrencies has redefined the global financial landscape, enabling decentralized and borderless transactions. While digital assets offer efficiency, innovation, and financial inclusion, they have also introduced new avenues for financial crime. This chapter critically examines the intersection of cryptocurrency and illicit financial activity, with a focus on typologies such as money laundering, terrorist financing, ransomware payments, investment fraud, and tax evasion. Through an analysis of real-world cases and peer-reviewed research, this chapter highlights how features such as pseudonymity, decentralized finance, and privacy-enhancing technologies have complicated regulatory enforcement and forensic tracking. This chapter also provides a comparative overview of global regulatory responses, including frameworks from the United States, European Union, Singapore, India, and China, as well as guidance from international institutions such as the Financial Action Task Force and the Organization for Economic Co-operation and Development. Key challenges such as legal ambiguity, technological complexity, and institutional fragmentation are explored in depth. In response, this chapter identifies emerging opportunities to strengthen oversight, including blockchain analytics, regulatory sandboxes, supervisory colleges, and capacity-building initiatives. It concludes by recommending a coordinated, adaptive, and risk-based regulatory approach that balances innovation with accountability.
