IBM Connects Digital Asset Platform With Swift to Bring Banks Closer to 24/7 Payments

Key Points

• IBM has integrated its Digital Asset Haven with Swift’s blockchain-based shared ledger.
• The setup allows banks to use ISO 20022 messaging for tokenized deposit transactions.
• Swift’s network connects around 12,500 financial institutions in more than 200 markets.
• 17 financial institutions are already piloting the system following its earlier launch.
• IBM is also offering on-premises deployment on IBM Z and LinuxONE, giving regulated banks greater control over digital assets and private keys.

IBM is making another push into the digital side of banking, this time by connecting its Digital Asset Haven platform with Swift’s blockchain-based shared ledger. The idea is fairly straightforward. Banks can use existing financial messaging standards to work with tokenized deposits without having to completely rebuild the systems they already use.

The integration uses ISO 20022 messaging, a standard already widely used in financial services. IBM says this can allow institutions to instruct tokenized deposit transactions through familiar banking workflows while taking advantage of digital assets that can move around the clock.

That could matter as banks experiment with tokenized versions of traditional financial assets. Instead of treating blockchain-based transactions as a completely separate system, the IBM and Swift setup is designed to connect them with existing banking infrastructure.

Swift's network gives the project a fairly large potential reach. The organization connects around 12,500 financial institutions across more than 200 markets. According to FF News, 17 first-mover banks are already piloting these types of transactions following the launch of Swift's shared ledger initiative at Sibos 2025.

The other major part of IBM's announcement is security. IBM is introducing an on-premises deployment option for Digital Asset Haven on its IBM Z and LinuxONE systems. That means highly regulated financial institutions can run the platform inside their own data centers instead of relying entirely on a public cloud environment.

For banks handling assets such as stablecoins and tokenized deposits, keeping control of sensitive information and cryptographic keys can be a major consideration. IBM says its infrastructure can use Crypto Express hardware security modules, allowing private keys to remain within the secured environment.

IBM also points to a reported 99.999999% system availability for the infrastructure. The setup includes confidential computing capabilities designed to separate production, testing and development environments. IBM says auditable key ceremonies can also help institutions meet documentation and compliance requirements.

The bigger piece of the announcement is the attempt to make tokenized transactions fit into the systems banks already understand. ISO 20022 provides standardized messaging, so financial institutions do not necessarily have to create completely new messaging workflows specifically for distributed ledger technology.

That could lower some of the technical hurdles for banks interested in tokenized deposits. Instead of replacing their existing compliance and messaging infrastructure, institutions can potentially connect digital asset operations with familiar processes.

IBM's Tom McPherson, General Manager of IBM Z and LinuxONE, said financial institutions are moving toward a model where traditional and tokenized assets need to operate alongside each other. He said the infrastructure needs to combine digital asset capabilities with the security, resiliency and regulatory requirements expected by regulated financial institutions.

The move also shows how the financial industry is gradually trying to connect traditional banking infrastructure with blockchain-based systems. Tokenized deposits are still an emerging area, but IBM and Swift are focusing on the practical side of making them work within existing banking operations.

For banks, the appeal is less about replacing everything they already have and more about adding digital asset capabilities without giving up control over security, messaging and compliance.
