Top central banking figures from the United States and the United Kingdom clashed over the future of digital currency this weekend at the 32nd Dubrovnik Economic Conference in Croatia. The diverging perspectives highlight a growing geopolitical rift regarding how global financial superpowers plan to manage the explosion of private, dollar-pegged digital assets.
Federal Reserve Governor Christopher Waller delivered a forceful defense of stablecoins, arguing that private digital currencies inherently expand the global dominance of the U.S. dollar. Conversely, Bank of England policymaker Megan Greene offered a starkly pessimistic view, predicting that the current stablecoin market is merely a temporary phenomenon destined to collapse as traditional commercial banks finally modernize their own digital infrastructure.
The U.S. Case for Digital Dollarization
Waller framed stablecoins not as a threat, but as an aggressive tool for extending American monetary policy. According to coverage from Seeking Alpha, Waller argued that when foreign populations adopt dollar-backed stablecoins to escape their own volatile local currencies, they are effectively entering a fixed exchange rate system.
This dynamic forces foreign markets to “import US monetary costs,” functionally increasing the Federal Reserve’s influence over global retail transactions. Waller also noted that stablecoins introduce much-needed competition into a stagnant payment system, driving down transaction fees across the board.
Perhaps most significantly, Waller used the panel to publicly declare the death of Central Bank Digital Currencies (CBDCs). He noted that almost every major central bank in the world has functionally abandoned their sovereign digital currency projects, dismissing them as “a solution in search of a problem.” Currently, only the European Central Bank (ECB) and China remain heavily invested in developing state-backed digital currencies.
The U.K. Rebuttal: The Rise of Tokenized Deposits
Megan Greene countered Waller’s optimism by projecting a rapid extinction event for private stablecoins. She argued that the demand for these assets will “soon fade” entirely over the next five years.
Greene’s thesis, as reported by Investing.com, centers on the inevitable adoption of “tokenized deposits”—digital, blockchain-integrated versions of traditional commercial bank deposits.
She acknowledged that commercial banks have been incredibly slow to innovate in this space because they “don’t want to lose the fees” associated with legacy banking infrastructure. However, Greene argued that as stablecoins continue to successfully siphon away traditional deposits, major banks will be forced to adapt. Once commercial banks offer tokenized deposits backed by their massive institutional weight and regulatory security, Greene believes retail users will abandon private stablecoins entirely.
What the Split Means for the Future of Global Finance
The philosophical divide between the Federal Reserve and the Bank of England signals a highly volatile regulatory environment for the digital asset industry in 2026. If Waller’s vision holds, the U.S. is positioning itself to tacitly encourage the proliferation of dollar-pegged stablecoins as a vehicle for digital imperialism, exporting the dollar’s dominance without needing to build a complex, politically unpopular CBDC.
If Greene’s prediction is accurate, the current multi-billion dollar stablecoin market is living on borrowed time. Traditional banking institutions, despite their current inertia, possess the regulatory lobbying power and capital to crush private stablecoin issuers once they finalize their own blockchain-integrated deposit systems.
