IBM Connects Banking Platform to Swift Blockchain for 24/7 Payments

IBM has taken another step toward bringing blockchain technology into traditional banking, connecting its Digital Asset Haven platform to Swift’s new blockchain-based shared ledger. The integration, announced on September 24, allows participating financial institutions to instruct transactions involving tokenized bank deposits through Swift’s ledger using the existing ISO 20022 messaging standard.

In practical terms, banks can use their familiar payment infrastructure to initiate digital money transfers around the clock, including nights and weekends, rather than relying entirely on traditional banking-hour windows.

Swift launched its blockchain-based ledger earlier this year with a group of 17 financial institutions participating in its initial tokenized-deposit pilot. The initiative is designed to allow regulated banks to move tokenized deposits across borders while maintaining existing compliance and risk-control processes.

IBM’s Digital Asset Haven provides the infrastructure needed for financial institutions to connect to permissioned blockchain networks, including Swift’s shared ledger.

The new beta integration includes an ISO 20022 messaging adapter. This means banks can continue using a payment messaging format they already understand instead of having to build completely new blockchain-specific workflows.

IBM says financial institutions participating in Swift’s program have already tested tokenized deposits using Digital Asset Haven.

Tokenized deposits are digital representations of money held as deposits at regulated banks. Rather than introducing a new cryptocurrency, the approach allows banks to put existing forms of bank money onto blockchain infrastructure for faster and more programmable transactions.

One important detail is that 24/7 transaction instructions do not mean every part of the traditional banking settlement process has suddenly become fully blockchain-based.

Swift says its ledger can allow participating banks to move tokenized deposits around the clock before final settlement takes place through existing financial systems. IBM likewise describes the system as supporting 24/7 digital-asset movement while final settlement continues through established infrastructure.

That distinction is important because it means the new system is being built alongside existing banking infrastructure rather than immediately replacing it.

Alongside the Swift integration, IBM announced an on-premises beta version of Digital Asset Haven.

The deployment is designed to run inside a financial institution’s own data centre on IBM Z and LinuxONE systems, allowing organizations to manage digital assets without relying on public-cloud infrastructure.

IBM says the setup is intended to give banks greater control over their digital-asset operations, including key management and security.

Swift currently connects more than 12,500 financial institutions across more than 200 markets. Its blockchain ledger is initially being tested by 17 banks, making the current rollout a relatively small pilot compared with Swift’s broader global network.

The development highlights a broader shift in financial services: instead of blockchain existing separately from traditional banking, major financial institutions are increasingly exploring ways to connect blockchain-based assets and settlement systems to the infrastructure banks already use.

For now, IBM’s Swift integration remains in beta. Its wider impact will depend on how successfully banks scale tokenized deposits and whether blockchain-based payment infrastructure can eventually support larger volumes of real-world cross-border transactions.

The direction, however, is becoming clearer: traditional banks are experimenting with blockchain without necessarily abandoning the regulated financial systems they already depend on.
