Digital Money Across Borders

"Rapid ongoing progress with digital technologies has increased the prospects for adoption of new forms of digital money for both domestic and international transactions. These include central bank digital currencies (CBDCs) and the so-called global stable coins (GSCs) proposed by large technological companies or platforms. This paper explores the complex interactions between the incentives to adopt and use CBDCs and GSCs across borders and discusses the potential macro-financial effects."--Abstract.

Cross-border payments are expensive, slow, and opaque. These problems reflect multiple frictions, many of which boil down to limited trust among counterparties. Trust plays a central role in exchanging credit-based money. End users need to trust the issuers of money, and issuers must trust users to satisfy financial integrity requirements. Transactions are possible only where trust links exist. Interoperability between different forms of money can thus be conceptualized as the network of trusted links necessary for transactions. Traditionally, across borders, trust links involve exclusive bilateral credit relationships among correspondent banks. However, the fixed costs required to build these links foster an expensive and concentrated system. This paper interprets different payment arrangements in terms of the implied trust structures. It discusses how the tokenization of money alters trust links and allows for a potentially more efficient market structure to exchange money. The paper ends with a suggested global marketplace to trade tokenized money directly across borders.

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.

The rapid advent of digital money (DM) and assets raises questions about its implications for the functioning of the international monetary system (IMS). The low transaction costs of digital technologies, their accessibility and ease of automation, and their integration into existing digital services may bring opportunities in the form of higher financial interconnectedness and inclusion but may also add to risks. This paper explores the possible implications of DM for the IMS from the perspective of cross-border payments, international reserves and the supply of global safe assets, and the global financial safety net. To help inform the discussion, the paper presents empirical analyses of the effect of payment efficiency on international currency adoption for payment/transaction purposes as well as on reserve currency holdings, along with an illustrative modeling scenario of a DM-induced shock for the potential demand for global financial safety net resources.

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.

Many central banks are currently exploring the possibility of issuing retail central bank digital currency (CBDC). While the primary objective varies between jurisdictions, many central banks consider improved cross-border payments as a potential benefit and previous work has shown that CBDC can help overcome some of the frictions in cross-border payments. CBDC is a safe and liquid asset reducing the number of financial intermediaries and the settlement risk. Designing CBDC systems for cross-border payments is not fundamentally different from tailoring other payment systems. However, the roles and responsibilities might be slightly different in a CBDC system, and the central bank may play a more pivotal role given CBDC’s nature as public money as opposed to commercial bank money. This note draws lessons from ongoing experimentation and research to identify design and policy considerations when developing retail CBDC systems so it may be compatible for cross-border payments. The note focuses on retail CBDC—a CBDC primarily targeting households and non-financial firms—and leaves wholesale CBDC considerations for future work, although many of the discussions are applicable to wholesale CBDC and other forms of money as well.

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.

The global central banking community is actively exploring Central Bank Digital Currencies (CBDCs), which may have a fundamental impact on both domestic and international economic and financial stability. Over 40 countries have approached the IMF to request assistance through CBDC capacity development (CD). Current IMF CBDC CD efforts have focused on facilitating peer learning and developing analytical underpinnings for staff advice to member countries. CD missions have aimed at helping country authorities answer questions about how to think about CBDCs. With more available country experiments and empirical evidence, IMF CD will evolve to provide increased value-added advice more tailored to country circumstances and more solidly anchored in empirical and analytical work, and strengthen synergies with surveillance. This paper sketches a multi-year strategy to address frequently asked questions related to CBDC and outlines the process for developing a CBDC Handbook which will document emerging lessons, analytical findings, and policy views. The paper (1) explains the IMF’s approach to CBDC CD; (2) summarizes member countries’ emerging questions and challenges regarding CBDC; and (3) introduces the CBDC Handbook by motivating its scope and elucidating its governance structure.
