- Citi and Swift completed a major digital settlement trial that linked fiat and digital currencies without changing the current money system.
- The trial used existing Swift infrastructure with blockchain connectors to create a hybrid settlement model.
- The approach aims to cut settlement risk while preparing the industry for scalable digital asset transactions.
Citi and Swift completed a trial that is being viewed as a serious step toward modern settlement systems. The trial confirmed that fiat and digital currencies can settle against each other in a Payment-versus-Payment setup without altering the structure of the current banking system.
Tom Zschach noted that the real development is not the creation of new forms of money but the pattern the industry is now testing.
A global bank and a major financial utility were able to experiment inside existing rules, showing that modernization does not require a redesign of the money layer.
The test combined Swift’s network with blockchain-based tools. The setup linked traditional rails with distributed ledger networks, allowing both sides of the transaction to move in sync.
The aim was to demonstrate that settlement can become faster while reducing operational risk.
Ayesa Latif, who oversees FX products at Citi, said the work helped outline the type of infrastructure needed for digital currencies as banks move toward practical use cases.

Hybrid Model Bridges Blockchain and Traditional Finance
The experiment introduced an example of a hybrid model with blockchain technology included in the existing financial systems rather than substituting them.
Jonathan Ehrenfeld, who is the head of strategy at Swift, said that the organization was in a position to become the lone secure bridge connecting tokenized markets and the traditional financial system.
That opinion was assisted by the trial based on Swift’s current reach and additional orchestration layers of transactions based on digital value. It is also published at a time when tokenized systems are experiencing high growth.
Citi GPS projects the stablecoin market will grow to $1.9 trillion by 2030 as regulation becomes more certain and applications are expanded. The volume of monthly transactions in stablecoins is approaching USD1 trillion, and it provides an idea of the activity of these networks.
Despite this action, the conversion between fiat and digital currencies is still challenging because of the structural variations between bank accounts and blockchain wallets. This is the gap that the initiative of Citi and Swift targets to fill.
How the Trial Achieved Synchronized Settlement
Citi and Swift developed a messaging standard that monitored all the trade initiation to settlement confirmation. It identified the transaction data requirements that are unique to both fiat and digital asset transactions.
The model employed escrow functionality to cope with the fact that the transactions in blockchain are irreversible, and yet both parties are in line. An overall coordinator synchronized every action such that the payment legs would settle simultaneously.
The test involved USDC tokens on the Sepolia testnet on Ethereum so as to approximate almost real-life conditions. Both companies will keep on improving the model with the industry partners as both strive to achieve scalable digital asset settlement standards.
