Key Points:
- Bank of England policymaker Megan Greene warns that the popularity of stablecoins could fade soon as commercial banks introduce tokenized deposits.
- Greene predicts that within five years, digital versions of traditional bank deposits will replace stablecoins as the primary form of private digital money.
- U.S. Federal Reserve Governor Christopher Waller offered a contrasting view on the same panel, defending stablecoins as useful, cost-reducing innovations.
- Commercial banks have delayed the development of digital deposits to protect fee revenues, but rising competitive pressure will likely force a shift in strategy.
The global stablecoin market is facing a critical crossroads as central bankers debate the long-term viability of private digital currencies. Speaking on Sunday, May 31, 2026, at the 32nd Dubrovnik Economic Conference in Croatia, Bank of England policymaker Megan Greene presented a challenging outlook for the digital asset industry. Greene argued that the current massive demand for stablecoins might soon fade, giving way to tokenized deposits, which represent digital versions of traditional, regulated bank deposits. Her remarks inject a dose of caution into a sector that has recently experienced rapid mainstream integration through consumer fintech apps.
Greene, who serves as an external member of the Bank of England’s Monetary Policy Committee, delivered a stark timeline for this transition. “I think tokenized deposits are probably going to take over from stablecoins and five years from now, I suspect we might wonder why we were talking about stablecoins,” she told attendees during a panel discussion on stablecoins and monetary policy. This perspective suggests that the current era of stablecoin dominance is merely a temporary phase of financial technology, rather than the permanent foundation of a new global payments architecture.
The shifting dynamic will likely depend on how commercial banks react to the threat of losing traditional deposits to digital assets. Greene pointed out that while markets currently exist for central bank digital currencies, stablecoins, and tokenized deposits, traditional commercial banks will emerge as the ultimate winners. Once these institutions realize they risk losing their core deposit bases to private crypto assets, they will rapidly pivot to defend their ground. By deploying their own blockchain-based, regulated digital deposits, banks can offer retail and corporate clients a much safer, fully insured alternative to algorithmic or fiat-backed stablecoins.
Historically, commercial banks have hesitated to develop their own digital or tokenized deposit systems. Greene explained that this delay stems from a desire to protect lucrative existing transaction fee revenues. “Digital deposits haven’t taken off because commercial banks don’t want to lose the fees,” she observed during the Dubrovnik panel. However, she emphasized that banks will lose these fees regardless of their actions as decentralized networks and fintech competitors expand. Once commercial bankers accept this inevitable reality, she expects them to channel significant capital and research into building out native, tokenized deposit infrastructures.
Greene’s cautious stance contrasted sharply with the views of U.S. Federal Reserve Governor Christopher Waller, who shared the Dubrovnik stage with her. Waller defended stablecoins as valuable, cost-reducing payment instruments. He argued that regulators should not quash these private financial innovations with excessive or restrictive rules. Waller’s defense reflects a more hands-off approach often favored by some U.S. financial regulators, who view dollar-pegged stablecoins as a tool to reinforce the global dominance of the U.S. dollar in international trade and remittance corridors.
This policy debate arrives at a moment of intense commercial activity for stablecoins, even as their overall issuance has recently plateaued. Major consumer fintech companies are aggressively integrating dollar-backed rails into their platforms. For instance, SoFi recently launched its SoFiUSD stablecoin on both the Ethereum and Solana blockchains. At the same time, Block’s Cash App began rolling out support for USD Coin across Solana, Ethereum, Polygon, and Arbitrum to its 59 million monthly active transacting users. The massive success of these product rollouts shows that consumers value instant, cheap settlement, but it also increases the urgency for central banks to establish strict regulatory guardrails.
Central bankers remain deeply concerned about the broader systemic risks posed by private stablecoins to national economies. Greene raised several flags regarding their stability, highlighting how easily these assets can facilitate illicit financial transactions and bypass standard anti-money laundering controls. Additionally, policymakers fear that a massive flight of capital from commercial banks into stablecoins could diminish the efficacy of national monetary policy. During economic shocks, sudden and large-scale withdrawals of bank deposits into stablecoins could trigger liquidity crises, making it harder for central banks to manage interest rates and control inflation.
The Bank of England has historically taken a highly conservative stance on digital assets to shield the traditional banking sector from systemic risk. Earlier proposals suggested imposing strict caps of £20,000 on individual holdings and £10 million on corporate holdings of stablecoins to prevent sudden bank runs. However, Bank of England Deputy Governor Sarah Breeden recently indicated that the central bank might relax some of these conservative limits in response to feedback from the financial services industry. Regulators are currently exploring more flexible frameworks that balance financial stability with the need to encourage technological innovation in the United Kingdom’s financial markets.
Ultimately, the transition of the digital asset landscape will depend on which technology can deliver the most secure and efficient means of exchange. While stablecoins currently enjoy a first-mover advantage as the primary currency of decentralized finance, tokenized deposits backed by licensed, commercial banking systems represent a formidable challenger. As Megan Greene’s warning suggests, the financial industry is only in the opening chapters of this digital money evolution. Whether stablecoins remain a permanent payments layer or simply serve as a temporary bridge to highly regulated, bank-backed digital deposits will shape the global financial system for decades to come.
