A group of US banks is planning to launch a nationwide blockchain network called BankChain by 2027. The network is designed as shared infrastructure for tokenized deposits and onchain payments, part of a growing push by banks to build their own rails rather than rely on public chains.
Why banks are building their own chain
BankChain isn't the first bank-led network of its kind, but it's one of the most ambitious in the US. The idea is simple: give banks a common, permissioned ledger where they can settle tokenized deposits with each other directly, cutting out the slow and costly intermediaries that typically sit between institutions.
The move comes as more banks experiment with tokenized money. Rather than each institution running its own private ledger, a shared network lets them move funds without needing to convert to traditional payment systems at every step.
What BankChain will actually do
The network's focus is on tokenized deposits and onchain payments. That means banks issue digital representations of their customer deposits on the chain, and those tokens can be transferred between banks in near real time. The target is to have the system live by 2027, though a lot of the technical and regulatory details are still being worked out.
There's no single company in charge. The banks are working together, which is unusual in an industry where competitors rarely share core infrastructure. But the pitch is that a shared network is more useful than a siloed one—if every bank is on the same chain, then payments between any two institutions just work.
Tokenized deposits, explained
Tokenized deposits aren't the same as stablecoins. A stablecoin is a separate token backed by reserves, while a tokenized deposit is a digital representation of an actual bank deposit. It's still money you hold at a bank, just wrapped in a token that can move on a blockchain.
That distinction matters for regulation. Bank deposits are already insured and supervised, so tokenized versions stay within the banking system. The banks are betting that regulators will be more comfortable with a bank-run network than with letting stablecoin issuers take over the payment rails.
What to watch next
BankChain is still in the planning stage. The group hasn't publicly named which banks are involved or announced a specific technical design. The 2027 deadline gives them room to figure out the details, but also sets a clock—if banks can't agree on standards, the project could slip.
The bigger question is whether other banks will want to join. A network is only useful if enough institutions are on it, and so far the group hasn't said how many banks have signed up. That's the number to watch in the coming months.
