Swift to Add Blockchain-Based Ledger to Its Infrastructure Stack in Groundbreaking Move

Published: September 29, 2025

Swift today announces that it will add a blockchain-based shared ledger to its technology infrastructure, a pivotal step for global finance that promises to make instant, always-on cross-border transactions possible at unprecedented scale.

Swift already has kicked off work with a group of more than 30 financial institutions globally to design and build the ledger, focused on a first use case of real-time 24/7 cross-border payments and starting with a conceptual prototype by Consensys. Swift will work at pace to complete the prototype in phase one and define its future phases of work.

The ledger will extend Swift's financial communication role into a digital environment, facilitating banks’ trusted and scalable movement of regulated tokenised value across digital ecosystems. Swift’s focus is on the infrastructure – the types of tokens that will be exchanged on the ledger is the territory of commercial and central banks and Swift will work with them on how to complement and make use of this new infrastructure.

It is envisaged that the ledger -- a secure, real-time log of transactions between financial institutions -- will record, sequence and validate transactions and enforce rules through smart contracts. It will be built for interoperability, both with existing and emerging networks, while maintaining the trust, resilience and compliance synonymous with Swift and critical to the secure functioning of global finance.

Announcing the ledger at Swift’s annual flagship Sibos conference in Frankfurt today, Swift CEO Javier Pérez-Tasso commented “We provide powerful and effective rails today and are moving at a rapid pace with our community to create the infrastructure stack of the future. Through this initial ledger concept we are paving the way for financial institutions to take the payments experience to the next level with Swift’s proven and trusted platform at the centre of the industry’s digital transformation.”

Financial institutions from 16 countries are providing Swift feedback on the design of the ledger, and, following successful development and proof of concept, Swift will work with its global community on implementation. The group of banks working on the design includes:
