Kiffmeister’s #Fintech Daily Digest (20230909)*

How should central banks explore central bank digital currency?

The IMF published a paper (co-written by yours truly) that proposes a dynamic central bank digital currency (CBDC) 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. 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.

A guide to central bank digital currency product development

The IMF published a paper that 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.

Open banking, shadow banking and regulation

The Bank of England (BoE) published a paper that argues that open banking will create diverse banking models: competitive banks (serving depositors who adopt open banking) and monopolistic banks (serving the other depositors). In equilibrium, at the margin, the profit of competitive and monopolistic banks should be equal. Hence, the system-wide impact of any policy change cannot be judged solely by the impact on a typical monopolistic or competitive bank, the impact on relative profitability also matters since this can lead banks to move from one banking type to another.
