Programmability is at the heart of ongoing work on the future of money and payments by central banks around the world. Despite its potential, there is growing concern that programmability conflicts with the provision of “good” money. This paper overviews key principles of “good” money and argues that the discourse on programmability inadequately differentiates between programmable money, which is generally negatively viewed, and programmable payments, which is generally accepted as part of the future. We provide a framework for programmable monetary systems that sharply distinguishes between programmable money and programmable payments. We show that our framework nests a broader set of financial arrangements and revisit the debate on programmability in the design of monetary systems.
