How Should Central Banks Explore Central Bank Digital Currency?
Digitalization of the economy provides both challenges and opportunities. Central banks should ensure that they have the capacity to continue to meet their policy objectives in the digital age. It is in this context that central bank digital currency (CBDC) should be evaluated. If designed appropriately, CBDCs could allow central banks to modernize payment systems and future-proof central bank money as the pace and shape of digitalization continues to evolve. However, the decision to proceed with CBDC exploration and an eventual launch would need to be jurisdiction specific, depending on the degree of digitalization of the economy, the legal and regulatory frameworks, and the central bank’s internal capacity. This paper proposes a dynamic decision-making framework under which the central bank can make decisions under uncertainty. A phased and iterative approach could allow central banks to adjust the pace, scale, and scope of their CBDC projects as the domestic and international environment changes.
Capital Flow Management Measures in the Digital Age (2)
This fintech note looks at how capital flow measures (CFMs) could be implemented with central bank digital currency (CBDC), and what benefits, risks and complexities could arise. There are several implications of the analysis. First, CBDC ecosystems should generally be designed such that they can accommodate the introduction of CFMs. Second, thanks to the programmability of the payment infrastructure given by the new digital technologies, certain CFMs could likely be implemented more efficiently and effectively with CBDC compared to the traditional system. Third, implementing CFMs requires central banks to collaborate on practices and standards. Finally, CFMs on CBDC need to operate alongside traditional CFMs.
A Guide to Central Bank Digital Currency Product Development
As central bank digital currency (CBDC) projects progress around the world, there is increased need for a project management methodology that is appropriate for CBDC. This paper develops a CBDC-specific project management methodology that establishes a common terminology and offers guidance to development teams on best practices for addressing the complex requirements and risks associated with CBDC. It is centered on an original five-step approach called the “5P Methodology”: preparation, proof-of-concept, prototypes, pilots, and production. The methodology emphasizes a phased approach to CBDC research and development, with strong focus on research preparation, experimentation and testing, risk management, stakeholder engagement, and cyber resilience.
Fintech and Financial Services
A new wave of technological innovations, often called “fintech,” is accelerating change in the financial sector. What impact might fintech have on financial services, and how should regulation respond? This paper sets out an economic framework for thinking through the channels by which fintech might provide solutions that respond to consumer needs for trust, security, privacy, and better services, change the competitive landscape, and affect regulation. It combines a broad discussion of trends across financial services with a focus on cross-border payments and especially the impact of distributed ledger technology. Overall, the paper finds that boundaries among different types of service providers are blurring; barriers to entry are changing; and improvements in cross-border payments are likely. It argues that regulatory authorities need to balance carefully efficiency and stability trade-offs in the face of rapid changes, and ensure that trust is maintained in an evolving financial system. It also highlights the importance of international cooperation.
Central Bank Risk Management, Fintech, and Cybersecurity
Based on technical assistance to central banks by the IMF’s Monetary and Capital Markets Department and Information Technology Department, this paper examines fintech and the related area of cybersecurity from the perspective of central bank risk management. The paper draws on findings from the IMF Article IV Database, selected FSAP and country cases, and gives examples of central bank risks related to fintech and cybersecurity. The paper highlights that fintech- and cybersecurity-related risks for central banks should be addressed by operationalizing sound internal risk management by establishing and strengthening an integrated risk management approach throughout the organization, including a dedicated risk management unit, ongoing sensitizing and training of Board members and staff, clear reporting lines, assessing cyber resilience and security posture, and tying risk management into strategic planning.. Given the fast-evolving nature of such risks, central banks could make use of timely and regular inputs from external experts.
Digital Currencies and Energy Consumption
Whether in crypto assets or in CBDCs, design choices can make an important difference to the energy consumption of digital currencies. This paper establishes the main components and technological options that determine the energy profile of digital currencies. It draws on academic and industry estimates to compare digital currencies to each other and to existing payment systems and derives implications for the design of environmentally friendly CBDCs. For distributed ledger technologies, the key factors affecting energy consumption are the ability to control participation and the consensus algorithm. While crypto assets like Bitcoin are wasteful in terms of resources, other designs could be more energy efficient than existing payment systems.
Transforming Public Finance Through GovTech
Digital divide across countries and within countries continues to persist and even increased when the quality of internet connection is considered. The note shows that many governments have not been able to harness the full potential of digitalization. Governments could play important role to facilitate digital adoption by intervening both on supply (investing in infrastructure) and demand side (increase internet affordability). The note also documents significant dividends from digital adoption for revenue collection and spending efficiency, and for outcomes in education, health and social safety nets. The note also emphasizes that digitalization is not a substitute for good governance and that comprehensive reform plans embedded in National Digital Strategies (NDS) combined with legal and institutional reforms are needed to ensure that governments can reap full benefits from digitalization and manage the risks appropriately.
Programmability in Payment and Settlement
Programmability in payment and settlement has yet to realize its potential to support policy goals such as efficiency, safety, and innovation. This paper proposes a comprehensive framework for understanding and evaluating programmability. It explores two key dimensions: external programmatic access, which is the ability for external participants to access the system data and functions with code, and internal programmatic capabilities, the extent to which internal execution of programs is supported and guaranteed. By developing strategies based on these dimensions, financial institutions, regulators, and related actors can better improve resilience, reduce costs and interoperability, all while managing associated risks. The resulting hybrid systems are coordinated efforts balancing the advantages of permissionless blockchains, such as composability, with regulatory requirements and a wider range of technologies. The paper describes these programmatic models to inform and guide the development of digital finance, bridging policy discussions with technical considerations.
ASAP: A Conceptual Model for Digital Asset Platforms
This working paper inaugurates the "Technology Fundamentals for Digital Finance" series, concentrating on the technical aspects of financial Digital Assets. The series aims to facilitate the use of a clear terminology in a nascent platform-oriented paradigm of financial infrastructures, by laying the groundwork for technical discussions on digital asset standards. The paper introduces a conceptual model named ASAP (Access, Service, Asset, Platform) for Digital Asset Platforms (DAP), leveraging insights from IT industry practices and experiments by central banks. The ASAP model is illustrated through examples and use cases of tokenized assets, to demonstrate the possible usage and merits of modeling Digital Asset Platforms with four layers. Just as the utilization of a seven-layer model (often refered to as TCP/IP) has been fundamental to the interoperability of the internet, it is anticipated that the four-layer ASAP model for Digital Asset Platforms will similarly promote cross-platform interoperability, including across various jurisdictions, paving the way for a more cohesive digital asset ecosystem.
Estimating Digital Infrastructure Investment Needs to Achieve Universal Broadband
We develop a detailed model to evaluate the necessary investment requirements to achieve affordable universal broadband. The results indicate that approximately $418 billion needs to be mobilized to connect all unconnected citizens globally (targeting 40-50 GB/Month per user with 95 percent reliability). The bulk of additional investment is for emerging market economies (73 percent) and low-income developing countries (24 percent). We also find that if the data consumption level is lowered to 10-20 GB/Month per user, the total cost decreases by up to about half, whereas raising data consumption to 80-100 GB/Month per user leads to a cost increase of roughly 90 percent relative to the baseline. Moreover, a 40 percent cost decrease occurs when varying the peak hour quality of service level from the baseline 95 percent reliability, to only 50 percent reliability. To conclude, broadband policy assessments should be explicit about the quantity of data and the reliability of service provided to users. Failure to do so will lead to inaccurate estimates and, ultimately, to poor broadband policy decisions.
