Digital central bank money, which is also referred to as central bank digital currency, or CBDC, would be another form of money alongside cash and deposits in central bank accounts that would be issued by a central bank. Deposits in central bank accounts in their existing form can be accessed only by a limited group of users, chiefly monetary policy counterparties of the Eurosystem. Depending on how it is designed, digital central bank money, on the other hand, would either offer new functions for the central bank’s existing counterparties (wholesale CBDC) or be available to users beyond selected counterparties. In the latter case – digital central bank money that can be used by enterprises and households – the term retail CBDC is also used. Up until now, digital central bank money has mainly been discussed as a concept, but it is clearly attracting growing interest in central bank circles. Indeed, some countries are already running practical tests on the use of central bank digital currency.
