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.

Financial inclusion is a key policy objective that central banks, especially those in emerging and low-income countries, are considering for retail central bank digital currency (CBDC). If properly designed to address the barriers to financial inclusion, CBDCs have the opportunity to gain acceptance by the financially excluded for digital payments. CBDC can then serve as an entry point to the broader formal financial system. CBDC has special aspects that may benefit financial inclusion, such as being a risk-free and widely acceptable form of digital money, availability for offline payments, and potentially lower costs and greater accessibility. However, CBDC is not a panacea to financial inclusion, and additional experience is needed to fully understand its potential impact.

This fintech note presents an analysis of the implications of central bank digital currency (CBDC) for monetary policy. In our framework, the implications of CBDC issuance on monetary policy are intermediated by its impact on key parts of the macroeconomic environment. The note also makes a distinction between “level effects”—whereby the introduction of CBDCs could tighten or loosen financial conditions as a shock—and “transmission effects,” whereby CBDCs change the impact of a given monetary policy shock on output, employment, and inflation. In general, the effects of CBDCs on monetary policy transmission are expected to be relatively small in normal times; however, these effects can be more significant in an environment with low interest rates or financial market stress.
