IBM Adapter Enables Banks to Use Existing Messages for Blockchain-Based Money Movement

IBM has released an adapter that allows banks to use their existing payment messages to instruct tokenized deposit transactions on Swift's blockchain ledger. This is a significant step towards making blockchain-based money movement routine for regulated banks.

The IBM Digital Asset Haven ISO 20022 Messaging Adapter eliminates the need for banks to build entirely new operational systems to communicate with a distributed ledger, which was previously the largest obstacle to bank participation in the Swift blockchain pilot.

The adapter translates existing payment application messages into the corresponding on-chain transaction instructions for Swift's shared ledger, using the standard ISO 20022 format. This means that compliance workflows, KYC checks, and sanctions screening remain anchored to the existing banking system, without requiring staff retraining on blockchain-native tooling.

As of September 25, 2026, seventeen first-mover institutions are piloting tokenized deposit transactions on the network, including Citi, HSBC, UBS, BNP Paribas, Standard Chartered, and Wells Fargo. The ledger has already recorded live cross-border transactions, with financial institutions like First Abu Dhabi Bank and Citi demonstrating that tokenized commercial bank money can support cross-border payments from the Middle East and Africa.

IBM also released a beta on-premises deployment of Digital Asset Haven, allowing regulated institutions to run the full platform inside their own data centers on IBM Z and IBM LinuxONE hardware, with no dependency on public cloud infrastructure. The on-premises configuration keeps both the solution layer and the key management layer entirely within the client's own environment.
