Central Bank Digital Currency (CBDC)

Abstract

This chapter examines Central Bank Digital Currencies (CBDCs), which are digital representations of a nation’s fiat currency issued by central banks. It explains the reasons for the increasing global interest in CBDCs, attributable to the proliferation of decentralized finance instruments such as cryptocurrencies, which present risks including money laundering and terrorism financing. In contrast to decentralized cryptocurrencies, CBDCs are government-backed, centralized and regulated. The chapter enlists the advantages of CBDCs, encompassing enhanced transaction speed, efficiency, privacy and financial security. The chapter further elaborates on various global initiatives in CBDC development. Countries like China, India, Nigeria, Jamaica and The Bahamas have implemented CBDCs with varying degrees of success. China has pioneered the endeavor with its e-yuan. India has launched two forms of CBDCs: CBDC-Wholesale (CBDC-W) for financial institutions and CBDC-Retail (CBDC-R) for the general public. Additionally, the chapter investigates the technological aspects of CBDCs, such as their integration with distributed ledger technology (DLT), smart contracts and different models of issuance (wholesale versus retail). Challenges pertaining to privacy, security, scalability and interoperability were also examined, underscoring the necessity for judicious design and regulation. The chapter concludes by asserting that CBDCs represent the future of digital finance, providing central banks with enhanced control over monetary policy while promoting financial inclusion and reducing dependence on private payment systems.
