The Bank for International Settlements, which acts as a bank for central banks, has released a new paper on retail central bank digital currencies. Central banks from Canada, Europe, Japan, Sweden, Switzerland, England, and the US are exploring the use of CBDCs for retail purposes. The group of central banks first published a paper in October 2020 and has now released a new paper called "Central bank digital currencies: ongoing policy perspectives." The banks are considering the need to ensure ongoing retail access to central bank money amidst ongoing changes in finance, technology, and society. They also see private innovation as an important factor in creating CBDCs.
