Central Bank Digital Currency Data Use and Privacy Protection


Book Description

This note offers a framework to help countries navigate, as well as tools to help them manage, the trade-offs between CBDC data use and privacy protection. It addresses retail CBDC, as data access and privacy-preserving considerations in a wholesale environment are similar to those of the traditional RTGS systems. It emphasizes the role of institutional arrangements, data collection, access and storage policies, design choices, and technological solutions. At a given level of preference for privacy, central banks can facilitate better use of CBDC data through robust transparency and accountability arrangements, sound policies, and judicious adoption of privacy-by-design approaches including the use of privacy-enhancing technologies.




Legal Aspects of Central Bank Digital Currency: Central Bank and Monetary Law Considerations


Book Description

This paper analyzes the legal foundations of central bank digital currency (CBDC) under central bank and monetary law. Absent strong legal foundations, the issuance of CBDC poses legal, financial and reputational risks for central banks. While the appropriate design of the legal framework will up to a degree depend on the design features of the CBDC, some general conclusions can be made. First, most central bank laws do not currently authorize the issuance of CBDC to the general public. Second, from a monetary law perspective, it is not evident that “currency” status can be attributed to CBDC. While the central bank law issue can be solved through rather straithforward law reform, the monetary law issue poses fundmental legal policy challenges.




Designing Central Bank Digital Currencies


Book Description

We study the optimal design of a central bank digital currency (CBDC) in an environment where agents sort into cash, CBDC and bank deposits according to their preferences over anonymity and security; and where network effects make the convenience of payment instruments dependent on the number of their users. CBDC can be designed with attributes similar to cash or deposits, and can be interest-bearing: a CBDC that closely competes with deposits depresses bank credit and output, while a cash-like CBDC may lead to the disappearance of cash. Then, the optimal CBDC design trades off bank intermediation against the social value of maintaining diverse payment instruments. When network effects matter, an interest-bearing CBDC alleviates the central bank's tradeoff.

As in previous years, one of the goals of the IFIP Summer School was to encourage the publication of thorough research papers by students and emerging scholars. The papers combine interdisciplinary approaches to bring together a host of perspectives, such as technical, legal, regulatory, socio-economic, social or societal, political, ethical, anthropological, philosophical, or psychological perspectives. *The summer school was held virtually.




The Rise of Digital Money


Book Description

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.




Cash Use Across Countries and the Demand for Central Bank Digital Currency


Book Description

The level and trend in cash use in a country will influence the demand for central bank digital currency (CBDC). While access to digital currency will be more convenient than traveling to an ATM, it only makes CBDC like a bank debit card—not better. Demand for digital currency will thus be weak in countries where cash use is already very low, due to a preference for cash substitutes (cards, electronic money, mobile phone payments). Where cash use is very high, demand should be stronger, due to a lack of cash substitutes. As the demand for CBDC is tied to the current level of cash use, we estimate the level and trend in cash use for 11 countries using four different measures. A tentative forecast of cash use is also made. After showing that declining cash use is largely associated with demographic change, we tie the level of cash use to the likely demand for CBDC in different countries. In this process, we suggest that one measure of cash use is more useful than the others. If cash is important for monetary policy, payment instrument competition, or as an alternative payment instrument in the event of operational problems with privately supplied payment methods, the introduction of CBDC may best be introduced before cash substitutes become so ubiquitous that the viability of CBDC could be in doubt.




Central Bank Digital Currency's Role in Promoting Financial Inclusion


Book Description

Financial inclusion is a key policy objective that central banks, especially those in emerging and low-income countries, are considering for retail central bank digital currency (CBDC). If properly designed to address the barriers to financial inclusion, CBDCs have the opportunity to gain acceptance by the financially excluded for digital payments. CBDC can then serve as an entry point to the broader formal financial system. CBDC has special aspects that may benefit financial inclusion, such as being a risk-free and widely acceptable form of digital money, availability for offline payments, and potentially lower costs and greater accessibility. However, CBDC is not a panacea to financial inclusion, and additional experience is needed to fully understand its potential impact.




Central Banking and Monetary Policy in the G20: Paradigms and Challenges


Book Description

Behind productive and prosperous economies are independent central banks that implement effective monetary policies. This observation is especially valid for the G20, which comprises the world’s top twenty economies in terms of gross domestic product and the largest stakeholders of the global economic system. These economies include Argentina, Australia, Brazil, Canada, China, France, Germany, India, Indonesia, Italy, Japan, Mexico, Russia, Saudi Arabia, South Africa, South Korea, Turkey, the United Kingdom, the United States, and the European Union. Three features of this book, which focuses on central banking and monetary policy in the G20, an intergovernmental platform, stand out: Firstly, as contemporary theories and global practices confirm, the main purpose of central banks is to ensure monetary and price stability, not despite the government but in cooperation with it. This principle is strongly emphasized here. Governments, which must maintain fiscal discipline, are key to the success of central banks in combating inflation and deflation. Secondly, since the authors of the book chapters come from various countries and academic institutions, the book offers a range of perspectives and intellectual richness. Without deviating from the book's main axis, the authors examine the changing paradigms in central banking and the increasing challenges of monetary policy. This examination is based on developed and emerging economies, integrations, financial organizations, and economic crises within the G20, informed by significant sources. Thirdly, this book offers university researchers, professional business practitioners, and curious readers the opportunity to explore and reflect on new concepts such as green central banking, digital money, and interest-free monetary policies, which have gained prominence in the wake of the global COVID-19 pandemic, alongside mainstream topics. It is hoped that this book, consisting of 14 chapters, will inspire those who wish to conduct new and renewed academic studies on global central banks and monetary policies and will fill a gap in the literature.




Implications of Central Bank Digital Currencies for Monetary Policy Transmission


Book Description

This fintech note presents an analysis of the implications of central bank digital currency (CBDC) for monetary policy. In our framework, the implications of CBDC issuance on monetary policy are intermediated by its impact on key parts of the macroeconomic environment. The note also makes a distinction between “level effects”—whereby the introduction of CBDCs could tighten or loosen financial conditions as a shock—and “transmission effects,” whereby CBDCs change the impact of a given monetary policy shock on output, employment, and inflation. In general, the effects of CBDCs on monetary policy transmission are expected to be relatively small in normal times; however, these effects can be more significant in an environment with low interest rates or financial market stress.




Some Lessons from Asian E-Money Schemes for the Adoption of Central Bank Digital Currency


Book Description

This paper synthesizes four lessons from the experiences of six Asian e-money schemes for central banks as they consider adopting central bank digital currency (CBDC): (i) CBDC should embody four attributes: trust, convenience, efficiency, and security; (ii) CBDC service providers can facilitate CBDC adoption through four channels: leveraging digital technology, targeting use cases, developing business models, and complying with legal and regulatory requirements; (iii) central banks could incentivize CBDC service providers to develop these four channels when considering CBDC adoption; and (iv) central banks may be able to establish data-sharing arrangements that preserve privacy while leaving room for CBDC service providers to explore the economic value of data.
