Joachim Nagel, President of the German Central Bank, endorses the rollout of euro stablecoins and a retail euro Central Bank Digital Currency (CBDC) to increase Europe's payment system independence. He highlights that these digital currencies can reduce cross-border costs and enable programmable payments by financial institutions using central bank money. Nagel warns that if US dollar stablecoins dominate the market over euro stablecoins, it could undermine European monetary policy and sovereignty.
