Banks are developing their own tokenized deposit chains, according to Sergey Nazarov, co-founder of the blockchain oracle network Chainlink. Nazarov said the move could reshape financial systems by improving efficiency and interoperability while preserving regulatory safeguards. The statement, made public this week, offers a rare window into how traditional finance is approaching blockchain technology — not through public networks like Ethereum, but through private, permissioned systems built in-house.
Why banks are choosing tokenized deposits
Tokenized deposits are digital representations of commercial bank money. Unlike stablecoins, which are typically issued by non-bank entities and backed by reserves, tokenized deposits are direct liabilities of the banks that issue them. That distinction matters. It means they can operate within existing regulatory frameworks rather than requiring new ones. Nazarov's comments suggest banks see this as a way to get the speed and programmability of blockchain without stepping outside the perimeter that supervisors already oversee.
The appeal is straightforward. Tokenized deposits can settle instantly, around the clock, and can be programmed to execute complex transactions automatically. For banks, that's a potential upgrade over traditional correspondent banking, which can take days to clear cross-border payments. It's also a defensive play: if customers migrate to stablecoins for fast, cheap transactions, banks risk losing deposits and fee revenue. By building their own tokenized systems, they keep those flows on their own balance sheets.
The interoperability question
Nazarov's point about interoperability gets at a thornier problem. If every major bank builds its own tokenized deposit chain, the financial system could fragment into a patchwork of walled gardens. A payment from one bank's chain to another's would require a bridge or a common protocol. That's where Chainlink comes in. The company provides oracle services that connect blockchains to external data and to each other. Its technology is already used by several financial institutions for cross-chain messaging and settlement experiments.
Still, the vision Nazarov describes is not a single shared ledger. It's a network of separate bank chains that can talk to one another. That's a meaningful difference from the original crypto ideal of one open, permissionless network. The banks want control over who can access their systems and under what conditions. Regulators want that too. The result is likely to be a hybrid model: private chains for issuance and settlement, with interoperability layers connecting them when needed.
Tokenized deposits could blur the line between traditional finance and crypto — but not in the way early enthusiasts hoped. Rather than replacing banks, the technology may end up entrenching them. Stablecoin issuers like Tether and Circle would face new competition from bank-issued deposits that carry implicit government backing and direct access to central bank reserves. Decentralized finance protocols, which rely on stablecoins as collateral, might eventually accept tokenized deposits too, though that would require regulatory clarity that doesn't yet exist in most jurisdictions.
Nazarov didn't name specific banks or timelines. He also didn't say whether the chains would be built on public networks or private ones. But his comments align with a broader trend: major financial institutions are moving from pilot projects to production systems. JPMorgan has its own tokenized deposit system, and several central banks are exploring wholesale digital currencies that would settle between institutions. The difference now is that the infrastructure is maturing, and the regulatory environment — at least in some regions — is becoming more accommodating.
The regulatory tightrope
Banks building tokenized deposit chains won't escape scrutiny. Deposit insurance, anti-money laundering rules, and capital requirements all still apply. The question is how supervisors will treat these new digital liabilities. If a tokenized deposit functions like a traditional deposit, it should be regulated like one. But if it can be transferred peer-to-peer without the bank's involvement, the picture gets murkier. Nazarov's mention of regulatory safeguards suggests the banks are designing their systems with those concerns in mind — permissioned access, identity verification, and transaction monitoring built into the chain itself.
That's a departure from the ethos of public blockchains, where anonymity and censorship resistance are features, not bugs. But it may be the only way to get institutional adoption at scale. The next step is likely to be more announcements from banks and infrastructure providers about specific deployments. Chainlink, for its part, is positioning itself as the connective tissue between these emerging systems. Whether that vision pans out depends on how quickly banks can agree on standards — and how far regulators will let them go.
