IBM Adds Swift Ledger Beta for Tokenized Deposits to Digital Asset Haven

Key Takeaways

• IBM’s beta ISO 20022 messaging adapter connects Digital Asset Haven to Swift’s blockchain ledger.
• Participating banks can use standard payment messages to instruct tokenized deposit transactions.
• A separate on-premises beta lets institutions manage digital assets inside their own data centers.

IBM announced on September 24 a beta messaging adapter connecting Digital Asset Haven to Swift’s blockchain-based shared ledger.

The new beta ISO 20022 messaging adapter lets financial institutions instruct tokenized deposit transactions using existing payment messaging standards.

IBM said financial institutions participating in Swift’s program have already tested tokenized deposits on the ledger through Digital Asset Haven.

Banks Retain Existing Payment Processes

The adapter lets banks build on existing payment message formats and operational procedures rather than blockchain-specific workflows. Participating financial institutions can continue using their own compliance processes, according to IBM.

Swift says the ledger supports 24/7 bank-issued tokenized deposits, with final settlements taking place through existing systems.

A transaction involving DBS Bank in Singapore and Citibank in New York illustrates that structure. DBS said on September 7 that it had completed a dollar payment with Citi’s New York office on September 5 using tokenized deposits through Swift’s ledger.

The ledger coordinated payment commitments and recorded interbank liabilities without holding the funds.

Swift Ledger Builds on Earlier Bank Pilots  

Swift announced the ledger at Sibos 2025 using a prototype built alongside Consensys, with input from more than 40 financial institutions. Seventeen institutions are participating in its initial tokenized-deposit use case. On a global scale, IMB said Swift connects 12,500 institutions across more than 200 markets.  

On July 9, 2026, Swift said its ledger is ready for initial use, with 17 banks from six continents preparing to pilot live transactions. The infrastructure moved from concept to activation in nine months.

According to Swift, the shared system connects bank-issued tokenized deposits held on the ledgers of individual institutions. Its initial focus is cross-border payments, with potential future applications including programmable money.

For banks, the intended benefits include more efficient liquidity use and payment availability across time zones. Swift said the design preserves the compliance, credit, and operational controls embedded in existing payment processing.

IBM Adds On-Premises Deployment

Alongside the Swift connection, IBM introduced an on-premises beta for Digital Asset Haven. The on-premises beta is designed to run on IBM Z and IBM LinuxONE systems within clients’ own data centers, without public-cloud dependency.

“The financial services industry is entering a new era where tokenized and traditional assets will need to move side by side,” said Tom McPherson, General Manager, IBM Z and LinuxONE. “As institutions modernize payments and prepare for a future of always-on transactions, they need infrastructure that combines innovation with the security, resiliency, and regulatory compliance requirements of regulated banking. By connecting to Swift’s shared ledger and extending IBM Digital Asset Haven to on-premises environments, IBM is helping clients participate in emerging digital asset networks while prioritizing control of their most critical financial operations.”

IBM introduced Digital Asset Haven in October 2025 in collaboration with wallet infrastructure provider Dfns. The platform combines custody, transaction management, and settlement capabilities for banks, governments, and regulated businesses.

It also includes policy-based transaction approvals and cryptographic key management across multiple blockchain networks.
