Cash use in most countries is falling slowly. On the margin, younger adults favor cash substitutes over cash. For older adults it is the reverse. Revealed preference tied to a changing population age structure seems to be the main influence on the demand for cash and why it is falling. Cash use may continue to fall, and card use (the main cash substitute) may fall by more, if CBDC is issued. The extent of this reduction depends on the demand for retail CBDC and the incentives (primarily transaction fees) that can play a determining role in CBDC adoption and use.
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.
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.
Digitalization is reshaping economic activity, shrinking the role of cash, and spurring new digital forms of money. Central banks have been pondering wheter and how to adapt. One possibility is central bank digital currency (CBDC)-- a widely accessible digital form of fiat money that could be legal tender. This discussion note proposes a conceptual framework to assess the case for CBDC adoption from the perspective of users and central banks. It discusses possible CBDC designs, and explores potential benefits and costs, with a focus on the impact on monetary policy, financial stability, and integrity. This note also surveys research and pilot studies on CBDC by central banks around the world.
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.
“A brilliant and lucid new book” (John Lanchester, New York Times Magazine) about why paper money and digital currencies lie at the heart of many of the world’s most difficult problems—and their solutions In The Curse of Cash, acclaimed economist and bestselling author Kenneth Rogoff explores the past, present, and future of currency, showing why, contrary to conventional economic wisdom, the regulation of paper bills—and now digital currencies—lies at the heart some of the world’s most difficult problems, but also their potential solutions. When it comes to currency, history shows that the private sector often innovates but eventually the government regulates and appropriates. Using examples ranging from the history of standardized coinage to the development of paper money, Rogoff explains why the cryptocurrency boom will inevitably end with dominant digital currencies created and controlled by governments, regardless of what Bitcoin libertarians want. Advanced countries still urgently need to stem the global flood of large paper bills—the vast majority of which serve no legitimate purpose and only enable tax evasion and other crimes—but cryptocurrencies are like $100 bills on steroids. The Curse of Cash is filled with revealing insights about many of the most pressing issues facing monetary policymakers, from quantitative easing to alternative inflation targeting regimes. It also explains in detail why, if low interest rates persist, the best way to reinvigorate monetary policy is to implement fully effective and unconstrained negative interest rates. Provocative, engaging, and backed by compelling original arguments and evidence, The Curse of Cash has sparked widespread debate and its ideas have moved to the center of financial and policy discussions.
New technologies are driving transformational changes in the global financial system. Virtual currencies (VCs) and the underlying distributed ledger systems are among these. VCs offer many potential benefits, but also considerable risks. VCs could raise efficiency and in the long run strengthen financial inclusion. At the same time, VCs could be potential vehicles for money laundering, terrorist financing, tax evasion and fraud. While risks to the conduct of monetary policy seem less likely to arise at this stage given the very small scale of VCs, risks to financial stability may eventually emerge as the new technologies become more widely used. National authorities have begun to address these challenges and will need to calibrate regulation in a manner that appropriately addresses the risks without stifling innovation. As experience is gained, international standards and best practices could be considered to provide guidance on the most appropriate regulatory responses in different fields, thereby promoting harmonization and cooperation across jurisdictions.
Theoretical and empirical analysis of de jure dollarization. With the persistent instability of international financial markets, emerging economies are exploring new ways to reduce exposure to capital flow volatility. Some analysts argue that financially open economies are best served by more flexible regimes, while others argue in favor of extreme exchange rate regimes that have a strong commitment to a fixed parity or dispense with an independent currency. The successful launch of the euro has made more realistic the prospect of replacing a national currency with a strong foreign one. Recent examples include the adoption of the US dollar by Ecuador and El Salvador. The introduction of a foreign currency as sole legal tender, termed full (de jure) dollarization, has been the center of much political and academic debate. This book provides a comprehensive analysis of the issues from both theoretical and empirical perspectives. The topics discussed include the role of balance sheet effects, the linkage between currency risk and country risk, the impact of dollarization on trade, financial integration and credibility, the implications of dollarization for the lender of last resort, and the institutional and political economy aspects of dollarization.

Technology is changing the landscape of the financial sector, increasing access to financial services in profound ways. These changes have been in motion for several years, affecting nearly all countries in the world. During the COVID-19 pandemic, technology has created new opportunities for digital financial services to accelerate and enhance financial inclusion, amid social distancing and containment measures. At the same time, the risks emerging prior to COVID-19, as digital financial services developed, are becoming even more relevant.
