According to Odaily, Joachim Nagel, the President of the German Central Bank, expressed uncertainty regarding the maximum amount consumers should hold of the potential digital Euro during a speech in Rome. Nagel referenced research by economists at the European Central Bank, suggesting that a per-person holding of 3000 digital Euros could effectively mitigate the impact on banking liquidity risks. However, the latest research from the German Central Bank indicates that the optimal amount may lie between 1500 and 2500 digital Euros per person. Nagel stated that further research will be conducted to determine the best value for this upper limit.
