Federal Reserve Governor Christopher Waller and Bank of England policymaker Megan Greene expressed contrasting views on the future of stablecoins at the Dubrovnik Economic Conference. Waller suggested that the growth of dollar-backed stablecoins could enhance the global influence of U.S. monetary policy, describing stablecoins as mere payment tools without inherent risks. In contrast, Greene argued that tokenized deposits might replace stablecoins within a few years, questioning the relevance of stablecoins in five years. She likened central bank digital currencies to a "turtle," stablecoins to a "rabbit," and tokenized deposits to a "rhino," predicting the rhino would ultimately prevail.
