“For our analysis on CBDC [Central Bank Digital Currency] in particular for general use, we tend to establish the equivalence with cash, and there is a huge difference there. For example in cash, we don’t know for example who is using a hundred dollar bill today; we don’t know who is using a one thousand peso bill today. A key difference with a CBDC is that the central bank will have absolute control on the rules and regulations that determine the use of that expression of central bank liability. And also, we will have the technology to enforce that. Those two issues are extremely important, and that makes a huge difference with respect to what cash is.” ~ Agustín Carstens, the general manager of the Bank for International Settlements (the central banker’s bank) at a 2020 IMF event, Cross-Border Payments—A Vision for the Future.
