A few countries have introduced central bank digital currencies (CBDCs), China is trialling a prototype yuan with 200 million users, India is gearing up for a pilot and some 130 countries representing 98% of the global economy are exploring digital cash. Commercial bankers fret about the costs and possible deposit bleeds as customers could move money into central bank accounts, while developing countries worry that an easily accessible digital dollar, euro or yuan could cause havoc in their systems. DEFINING A GLOBAL STANDARDA key unknown is whether the U.S. Federal Reserve or Bank of Japan will launch retail CBDCs. "The current adoption level of eNaira has been reflective of the early stage of CBDC awareness," the country's central bank said in a written response to questions, adding it had been "consistent" with expectations.
