The International Monetary Fund (IMF) is "working hard" on a concept of a global infrastructure that would ensure interoperability of settlements between digital currencies issued by national central banks. Such a platform would avoid an under-utilization of so-called central bank digital currencies (CBDCs), managing director Kristalina Georgieva told a conference in Rabat, Morocco.

"We are working on a principle of interoperability," she said. Such concept would involve a shared infrastructure that would avoid the emergence of "settlement blocks," which is the "last thing we want" to avoid further economic fragmentation, Georgieva said.
