Device Applications of Nonlinear Dynamics
This book is devoted to applications of complex nonlinear dynamic phenomena to real systems and device applications. In recent decades there has been significant progress in the theory of nonlinear phenomena, but there are comparatively few devices that actually take this rich behavior into account. The text applies and exploits this knowledge to propose devices which operate more efficiently and cheaply, while affording the promise of much better performance.
The Rise of Payment and Contracting Platforms
This Note explores the design and governance of platforms to enhance cross-border payments in line with public policy goals. While much innovation in recent years has more narrowly targeted end-user frictions, the vision in this paper is based on the mandate of the IMF, governed by the central banks and finance ministries of 190 member countries. Cross-border payments present the foundation for the global financial system, and its functioning is overseen by the IMF.
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.
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.
Cyber Resilience of the Central Bank Digital Currency Ecosystem
Over 100 central banks around the globe are exploring central bank digital currencies (CBDCs) to modernize payment systems. They aim to explore potential benefits, risks, and the broad range of new capabilities CBDCs might offer. Some view CBDC exploration as an opportunity to rethink their existing, legacy payment systems and build a resilient and secure infrastructure using modern technologies. However, a CBDC creates a vast and complex ecosystem that amplifies existing risk exposures and surfaces new ones. Given the implications of issuing a CBDC, it should be seen as a fundamental change in the way the central bank operates. This note considers experiences from live CBDCs and is informed by experiments conducted by central banks and international institutions for domestic use. It also draws from cybersecurity and resilience frameworks from standard-setting bodies.
Central Bank Digital Currency: Progress And Further Considerations
The paper briefs the Executive Board on the further considerations on CBDC. These cover the positioning of CBDC in the payments landscape, cyber resilience of the CBDC ecosystem, CBDC adoption, CBDC data use and privacy protection, implications for monetary policy operations, and cross-border payments with retail CBDC.
Positioning Central Bank Digital Currency in the Payments Landscape
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 payme...
Central Bank Digital Currency Adoption
Among the countries that have launched central bank digital currency (CBDC) or are conducting large-scale pilots, adoption remains slow and limited due to various challenges such as lack of public awareness and trust, preference for existing payment methods, and inadequate incentives for intermediaries. Central banks cannot take it for granted that CBDC, once launched, will be adopted and scaled up easily. Forming part of the CBDC Virtual Handbook, this paper aims to encourage policymakers to consider CBDC adoption early on, by arguing that successful CBDC adoption hinges not only on technical readiness and operational robustness, but also on strategic policy and design choices that target end-user and intermediary involvement from the outset. The paper introduces The REDI Framework which outlines various regulatory strategies, education/communication initiatives, design/deployment choices, and incentive mechanisms to prepare for CBDC adoption.
