The IMF is frequently approached by central banks seeking guidance on the balance between central bank digital currency (CBDC), fast payment systems (FPS), and electronic money (e-money) solutions. Common questions arising include: Do central banks need a CBDC when already equipped with other well-established digital payments systems? For central banks with less-developed solutions: Should central banks establish one system over the other? This discussion is then compounded by the reality of constrained resources. This note focuses on the comparison of retail CBDC—that is, the presence of digital central bank money available to the general public—with FPS and e-money systems from a payments perspective, and how CBDC may support a jurisdiction’s vision on payments in the digital age. The note does not seek to advocate for CBDC over an FPS or e-money. The balance of arguments for any one system may change over time, and the choice may not be mutually exclusive in many jurisdictions. In the future, it is possible to envisage the coexistence of an FPS, e-money, and CBDC in many payment landscapes across the world. Through good design, all three systems could meet central bank objectives such as payments efficiency and supporting financial inclusion; some benefits are unique to CBDC, such as maintaining access to central bank money in an increasingly digitalized age. While central banks will make choices unique to their circumstances, it remains important for central banks to establish a strategy that allows them (at minimum) to monitor trends and core benefits of multiple solutions as developments occur, to allow them to plan, adapt, and drive developments in their payments landscape.

This book delves into the intricacies of digital assets. With the increasing reliance on crypto and the potential adoption of digital currencies by central banks, our monetary system is at a critical point. The importance of taking the next step has become even more stringent, as evidenced by this systematic scientific reconstruction. Divided into five concentric parts, the book starts with a historical, technical and financial introduction to digital assets. It then explores the changing role of central banking and monetary economics in the upcoming era. Finally, it focuses on the broad legal issues arising from the new digital landscape, not shying away from exploring forward-thinking solutions and policies for the future. With the contributions of prominent international experts in the field, this collection supplies a transdisciplinary analysis based on the belief that complex phenomena can only be handled by complex solutions. This groundbreaking work aims to be more than just an academic treatise; it is a must-read for students, scholars, financial professionals, and all those who want to understand the emerging digital currency reality that many have yet to fully recognise.

In an era defined by rapid technological advancement, the nature of money finds itself at a crossroads, presenting both opportunities and challenges for global financial systems. The rise of Central Bank Digital Currencies (CBDCs) stands as a testament to this paradigm shift, offering the promise of efficiency, transparency, and financial inclusion. However, amidst the burgeoning interest in CBDCs, a pressing problem emerges: the lack of comprehensive understanding and insight into their development on a global scale. Recognizing this critical gap, Global Developments in Central Bank Digital Currency emerges as a guide for clarity in the complex landscape of monetary evolution. By synthesizing insights from diverse regions and jurisdictions, this book offers a holistic view of CBDC initiatives, unraveling the intricate web of motivations, challenges, and implications. From Africa to Asia, from Europe to Oceania, the book delves into country-specific developments, shedding light on the role of politics, culture, and informal institutions in shaping CBDC adoption.

Payments and financial market infrastructures are vital components of modern economies, yet they have often been overlooked by economists. However, any economic exchange, including financial market transactions, is matched by a payment leg, and the safety, efficiency, and immediacy of the payment, and the problem of linking the two legs of the transaction (“delivery-vs-payment”), remain universal challenges. The consequences of inefficiencies or interruptions in payment and settlement systems have immediate and significant impacts on the real economy. Moreover, payments and financial market infrastructures are also a matter of strategic importance for nation-states, and being excessively dependent on foreign providers has been proven to be a significant risk, as they can be “weaponized." This book provides a concise yet thorough introduction to payments and financial market infrastructures, exploring various types of risks, retail payments, payment systems, cross-border payments, central counterparties, FX operations, and central securities depositories. The final chapter investigates payment innovations, including unbacked crypto-assets (e.g. Bitcoin), stablecoins, and central bank digital currencies. The text outlines key activities and risk management frameworks, as well as examining the operational mechanics of different payment systems. The book emphasizes the importance of understanding the nature of transfer of financial claims and liabilities through the process of payment and settlement, providing financial account representations of payments wherever useful. The book concludes that the payment and financial market infrastructure space has been shaken by recent innovations, which are expected to lead to seismic shifts in payment technology, practices, and market structures.

This open access book tells the story of how Sweden is becoming a virtually cashless society. Its goal is to improve readers’ understanding of what is driving this transition, and of the factors that are fostering and hampering it. In doing so, the book covers the role of central banks, political factors, needs for innovation, and the stakeholders involved in developing a cashless ecosystem. Adopting a historical standpoint, and drawing on a unique dataset, it presents an academic perspective on Sweden’s leading role in this global trend. The global interest in the future of cash payments makes the Swedish case particularly interesting. As a country that is close to becoming a cashless economy, it offers a role model for many other countries to learn from - whether they want to stimulate or reduce the use of cash. This highly topical book will be of interest to politicians, researchers, businesses, financial service providers and payment service providers, as well as fintech start-ups, regulators and other authorities.

This paper marks the launch of a new IMF series, Fintech Notes. Building on years of IMF staff work, it will explore pressing topics in the digital economy and be issued periodically. The series will carry work by IMF staff and will seek to provide insight into the intersection of technology and the global economy. The Rise of Digital Money analyses how technology companies are stepping up competition to large banks and credit card companies. Digital forms of money are increasingly in the wallets of consumers as well as in the minds of policymakers. Cash and bank deposits are battling with so-called e-money, electronically stored monetary value denominated in, and pegged to, a currency like the euro or the dollar. This paper identifies the benefits and risks and highlights regulatory issues that are likely to emerge with a broader adoption of stablecoins. The paper also highlights the risks associated with e-money: potential creation of new monopolies; threats to weaker currencies; concerns about consumer protection and financial stability; and the risk of fostering illegal activities, among others.
