LONDON (Reuters) -A milestone move by the European Central Bank toward launching a digital euro within a few years means the time has come for the newest incarnation of money to prove its worth.
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.
The ECB's move on Wednesday to establish a pilot that could lead to a digital currency for the 20 countries that use the common currency, making it the first heavyweight Western central bank to formally forge ahead, could become a global blueprint.
Supporters say CBDCs will modernise payments with new functionality and provide an alternative to physical cash, which seems in terminal decline.
But questions remain why CBDCs represent an advance, with uptake low in countries such as Nigeria that have adopted them, as well as protests against the ECB’s plans, showing public concern about snooping.
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.
'WHAT IS MONEY?'
The ECB's plan «is a very big deal, and a lot of the rest of the world is watching this closely», said Josh Lipsky, who runs a global CBDC tracker at the Atlantic Council.
