IBM is making it easier for traditional banks to move money onchain by connecting its Digital Asset Haven platform to Swift’s blockchain-based shared ledger. The new beta integration allows financial institutions to initiate tokenized-deposit transactions using familiar ISO 20022 payment messages instead of building entirely new blockchain-specific workflows.
IBM Bridges Traditional Banking and Blockchain
IBM announced the integration on September 24 as part of an expansion of IBM Digital Asset Haven, its infrastructure platform for banks, governments and regulated organizations managing digital assets.
A new ISO 20022 Messaging Adapter allows Digital Asset Haven customers to connect with permissioned blockchain networks, including Swift’s shared ledger.
That creates an important bridge between traditional banking infrastructure and tokenized money.
Instead of requiring banks to completely redesign their payment systems around blockchain technology, IBM’s adapter translates familiar payment instructions into transactions that can interact with Swift’s blockchain infrastructure.
The new system includes:
- Integration between IBM Digital Asset Haven and Swift’s shared ledger
- Support for tokenized bank deposits
- Existing ISO 20022 payment messages
- Access to permissioned blockchain networks
- 24/7 movement of tokenized value
- Beta availability for participating financial institutions
Swift Already Has 17 Banks Testing Tokenized Deposits
IBM isn’t connecting to an experimental blockchain with no institutional users.
Swift’s shared ledger is already being used by 17 financial institutions across six continents to pilot tokenized-deposit transactions.
Participating banks include Citi, HSBC, UBS, BNY, Wells Fargo, BNP Paribas, Standard Chartered, DBS and MUFG Bank, among others.
Swift says the infrastructure allows participating banks to move tokenized deposits around the clock—including nights and weekends—before completing final settlement through existing financial infrastructure.
That distinction is important.
The shared ledger acts primarily as an orchestration layer connecting bank-issued tokenized deposits. Banks maintain control over their assets and funding, while final settlement continues through existing systems.
What Exactly Is a Tokenized Deposit?
A tokenized deposit isn’t the same thing as a traditional cryptocurrency or even a typical stablecoin.
It represents a customer’s deposit at a regulated bank in tokenized form. The digital token remains a liability of that bank, similar to money held in a conventional bank account.
That can potentially allow banks to combine the protections and regulatory structure of traditional deposits with blockchain features such as 24/7 transfers, programmability and faster movement between institutions.
IBM’s integration could make adopting that infrastructure easier because financial institutions can continue using messaging standards they already understand.
IBM Gives Banks an On-Premises Option
IBM also announced an on-premises version of Digital Asset Haven running on IBM Z and LinuxONE infrastructure.
That means highly regulated institutions don’t necessarily have to place their digital-asset infrastructure in a public cloud.
Banks can instead operate the platform inside their own data centers while maintaining control over sensitive information, digital assets and cryptographic keys.
IBM says its Crypto Express hardware security modules can keep private keys inside protected hardware environments.
The on-premises deployment is also currently in beta.
Swift’s Blockchain Push Is Moving Quickly
Swift announced its blockchain-based shared ledger at Sibos 2025 and developed it with input from more than 40 financial institutions.
The system moved from concept toward activation in approximately nine months. In July, Swift announced that the first 17 banks were preparing to pilot live tokenized-deposit transactions.
Swift says its network already connects approximately 12,500 financial institutions across more than 200 markets, giving the company a potentially enormous distribution network if tokenized deposits move beyond their current pilot stage.
The shared ledger uses an Ethereum Virtual Machine-compatible architecture based on Hyperledger Besu, but Swift operates the infrastructure while participating banks maintain control over their assets.
Traditional Finance Keeps Moving Onchain
IBM’s integration arrives as tokenized deposits gain momentum across global banking.
Canada’s six largest banks recently announced they are exploring a shared tokenized-deposit system, while institutions including HSBC, JPMorgan and Citi have been developing blockchain-based payment and deposit infrastructure.
Swift’s approach could potentially connect many of those individual banking systems rather than requiring every institution to operate inside the same proprietary blockchain ecosystem.
That may be the bigger story behind IBM’s announcement. Banks don’t necessarily have to abandon decades of financial infrastructure to move money onchain. IBM is instead building a bridge between the messaging systems they already use and Swift’s emerging blockchain network—bringing tokenized deposits into traditional banking without forcing banks to rebuild everything from scratch.
