Central bankers debate stablecoins versus tokenized deposits

TLDR

Central bankers are split on whether future digital money rails will be dominated by stablecoins or by tokenized bank deposits.

1. US Fed governor Christopher Waller defends dollar stablecoins as safe payment tools that can extend US monetary reach, while UK policymaker Megan Greene expects tokenized deposits to overtake them.
2. Greene and others worry that stablecoins drain bank deposits and complicate regulation, whereas tokenized deposits keep money inside banks under familiar rules and supervision.
3. For crypto users this points to a likely mix of public stablecoins, bank-issued tokens, and CBDCs, with regulation deciding which grows fastest and where real on-chain liquidity sits.

Deep Dive

1. What Central Bankers Are Arguing

At the Dubrovnik Economics Conference, US Federal Reserve governor Christopher Waller described dollar-backed stablecoins as a straightforward payment instrument that "brings competition into the payments world" and is "nothing dangerous" when properly regulated. He also argued that widespread use of dollar stablecoins lets other countries "import US monetary conditions," effectively extending US monetary policy abroad as if under a soft fixed exchange rate.

On the same panel, Bank of England policymaker Megan Greene took the opposite side, saying that "five years from now, I suspect we might wonder why we were talking about stablecoins" and predicting tokenized deposits will dominate instead. She framed the race as CBDCs (the tortoise), stablecoins (the hare), and tokenized deposits (the rhino), and said she would "put money on the rhino" according to conference coverage.

2. Why Tokenized Deposits Look Safer To Regulators

Greene and other officials highlight several perceived problems with stablecoins: they can be "not truly stable" if reserves or risk management are weak; they are used in some illicit flows; and, crucially, they pull deposits out of the banking system. That makes it harder for central banks to steer credit conditions through banks, and raises questions about who backstops runs on stablecoins.

Tokenized deposits, by contrast, are just regular bank deposits represented as on-chain tokens. They sit on bank balance sheets, stay under bank capital and liquidity rules, and are usually covered by deposit insurance. For regulators, that preserves existing oversight while still allowing 24/7 programmable transfers.

This is why Greene argues that once banks accept they will lose fee income anyway, they will invest heavily in digital deposits, and why legislators in the US and EU are debating whether they need special rules for deposit tokenization on top of standard banking law.

3. What It Means For Crypto Rails And Users

For crypto markets, the debate is not "stablecoins die, tokenized deposits win," but how these instruments will coexist and where liquidity concentrates.

1. Policy fights over stablecoin yield and bank competition have already slowed major US bills like the Digital Asset Market Clarity Act, which would set federal rules for stablecoins and trading platforms.
2. At the same time, large banks and infrastructures are building tokenization rails, from commercial-bank deposit tokens to securities platforms that settle on public chains such as Stellar and Ethereum, expecting big growth in tokenized assets over the next several years.
3. Ethereum, Solana and similar networks are positioning as settlement layers for both regulated stablecoins and tokenized real-world assets, tying their long term demand to whether regulators greenlight these models at scale.

Conclusion

Central bankers are not rejecting crypto-style money so much as negotiating which version fits their mandates: privately issued stablecoins, bank deposit tokens, or CBDCs. That choice will shape where real-world assets and payments settle on-chain, and which networks see durable demand. For now, expect overlapping experiments, regulatory friction, and a gradual tilt toward models that keep central banks control over monetary policy while still tapping blockchain efficiency.
