Analysts at Morgan Stanley estimated a digital euro can suck away 8% from the customer deposits of Eurozone banks. 90% of the world’s central banks are working on cryptocurrencies. The estimate of the analysts is simply based on a bear-case scenario where all the Europeans above the age of 15 would transfer 3000 Euros into an ECB-controlled digital wallet. Theoretically, the reduction in Euro Area total deposits defined as households & non-financial corporation deposits will be 873 billion euros or 8%. 3000 euros of deposits would be equivalent to converting 17%-30% of total deposits & 22%-51% of total household deposits.
