Major U.S. Banks Form Joint Private Blockchain Network

A group of major U.S. banks announced a partnership to build and jointly own and operate a shared private blockchain aimed at speeding settlement, reducing manual reconciliation and supporting tokenized cash and securities. The permissioned ledger will be used for interbank payments, securities settlement and other back-office functions among members.

The consortium outlined a governance structure in which participating banks will hold equity stakes, nominate board representatives and share operational responsibilities for the network. Access will be restricted: only approved financial institutions and service providers may operate nodes or validate transactions on the ledger.

Participants include large commercial and investment banks, custody banks and market infrastructure firms that manage payment flows and asset servicing for institutional clients. The group plans to run pilot programs covering a limited set of transactions before expanding services to more banks and clients, with a phased rollout of pilots expected in the coming months and broader commercial availability set on a timetable agreed by members.

The network will support tokenized representations of cash and securities and use smart contracts to automate settlement steps now performed manually by multiple custodians and reconciliation systems. The platform is being designed to integrate with existing core systems, custody ledgers and correspondent banking channels so adoption does not require replacing current infrastructure.

The shared ledger is expected to enable near-real-time settlement windows, reduce bilateral reconciliation and lower operational costs tied to trade processing and post-trade custody. Members plan to provide connectivity to institutional clients, broker-dealers and other regulated firms that need custody, payments or settlement services on the network.

Regulatory engagement is planned as part of the project. The banks will consult federal and state regulators and banking supervisors to align the network with rules on custody, settlement finality, capital and liquidity treatment, and anti-money-laundering controls. The consortium will also set technical and compliance standards for onboarding third-party technology vendors, cloud providers and node operators.

In the announcement the consortium wrote, “In collaboration we can deliver a common operating platform that streamlines processing, enhances resiliency and supports client demand for digital asset services.” Background materials describe the system as a permissioned, enterprise-grade blockchain with security controls, audit trails and the ability to segregate asset types.

The banks did not disclose initial capital commitments, the full list of founding members or detailed timelines for specific products. The group said technical specifications and a public timeline for pilots will be released in the coming weeks.
