According to Nic Carter, there is no effective definition of a Central Bank Digital Currency (CBDC) that does not also encompass the reserve balances that commercial banks hold at the Federal Reserve. Carter's analysis, shared via a tweet, suggests that this existing financial infrastructure effectively functions as a wholesale CBDC. This perspective challenges the common narrative around the future implementation of a digital dollar and implies that a form of CBDC is already integrated into the U.S. banking system, a critical consideration for traders evaluating the potential impact of new digital currencies on assets like Bitcoin (BTC) and the broader crypto market.
