US banks are pursuing shared blockchain infrastructure through BankChain Alliance, a network targeting a 2027 launch. Thirty-nine United States state banking associations have announced plans for the banking sector project.
The network is designed to support stablecoins, tokenised deposits and smart payments. Banks would design and operate it, with interoperability with other networks as a core goal.
An Observer Research Foundation analysis describes the initiative as a response to competitive pressure. Author Sauradeep Bag argues that US banks want programmable payments built around deposits rather than outside their own balance sheets.
US Banks Seek Shared Infrastructure
Kathy Kraninger, interim chair and chief executive officer of the Florida Bankers Association, described the project’s intended reach. The aim is regulated, secure infrastructure accessible to financial institutions of any size.
That includes small community banks unable to build such a system alone. BankChain Alliance is seeking a technology partner to lead development, according to the analysis.
The planned launch remains dependent on regulatory approval and banks’ participation. Bag identifies meaningful transaction volumes as important, alongside institutions choosing a shared network over proprietary systems.
The analysis places the alliance alongside blockchain efforts already undertaken by large US banks and international institutions. It presents the project as extending that approach to small and mid-sized banks.
Deposit Tokens Remain Claims On Banks
Bag distinguishes stablecoins from tokenised deposits by how the instruments operate. A tokenised deposit remains a deposit, sits within existing bank regulation and can pay interest.
It also remains a claim on a specific bank. The analysis says such deposits move less easily between banks than bearer instruments circulating on public blockchains.
BankChain Alliance and similar consortium efforts seek to address that friction. A deposit token issued by one member institution would be recognised across the wider network.
For US banks, the analysis links faster transfers to questions about lending capacity. Banks accept deposits redeemable at any moment while funding mortgages and business loans repaid over many years.
Bag cites research by Federal Reserve economists Rosie Levy and Srini Ramaswamy, published in August 2026. The researchers examined how faster, more interest-sensitive deposits could affect banks’ long-term lending.
They estimated a US$580 billion capacity loss if tokenisation reduced deposits’ effective duration by 10 percent. A 10-percent increase in sensitivity to interest rates would remove a further US$700 billion, the analysis reports.
Other Networks And Regulatory Questions
The analysis says JPMorgan’s Kinexys platform has processed more than US$3 trillion in cumulative transactions. It expanded in January 2026 to the Canton Network alongside its original private infrastructure.
Citi integrated Citi Token Services with its round-the-clock dollar clearing system in September 2025. Separately, The Clearing House is developing a bank-owned tokenised deposit network targeting the first half of 2027.

Bag says the practical questions for US banks include selecting a capable technology partner and securing approval. The alliance must also persuade institutions to connect to shared infrastructure rather than build separate alternatives.
