Central Bankers Clash Over the Future of Stablecoins and Tokenized Deposits

A sharp philosophical divide over the future of private digital money has emerged between senior central bankers on both sides of the Atlantic. Speaking at a conference in Dubrovnik, Croatia, Bank of England policymaker Megan Greene predicted that the market’s current fixation on stablecoins will likely fade into irrelevance within the next five years. Instead, she expects tokenized deposits—digital versions of traditional commercial bank accounts—to become the dominant layer of the digital financial system.

While stablecoins have surged in popularity over recent years, Greene pointed out that their market issuance has noticeably leveled off in recent months. She noted that while there is technically space in the broader ecosystem for central bank digital currencies, private stablecoins, and digital deposits, the legacy banking sector will ultimately force a shift. Once traditional commercial banks collectively recognize that they run a direct risk of losing their foundational deposit bases to non-bank crypto issuers, they will aggressively pivot to protect their territory by tokenizing their own deposits. In short, Greene suspects that five years from now, regulators and investors will wonder why they spent so much time discussing stablecoins in the first place.

U.S. Federal Reserve policymaker Christopher Waller offered a starkly different counter-perspective on the exact same panel, explicitly defending private stablecoins. Rather than viewing them as a systemic threat to traditional banking infrastructure, Waller characterized stablecoins as a genuine financial innovation that can meaningfully reduce real-economy transaction costs. He strongly cautioned against regulatory overreach, arguing that these private-sector instruments should not be quashed by excessive or reactionary rules. The debate highlights a lingering tension among global financial authorities: while some regulators view private stablecoins as an unstable risk to domestic bank deposits, others see them as an efficient evolutionary step for mainstream payments.
