Britain’s biggest banks have completed the first live customer transactions using tokenized sterling deposits, marking a significant step toward putting blockchain-based commercial bank money into real-world payments.

The transactions were carried out through the Great British Tokenised Deposit (GBTD) initiative, coordinated by UK Finance and involving Barclays, HSBC UK, Lloyds Banking Group, Monzo, Nationwide, NatWest and Santander. UK Finance announced the transactions on Sept. 24.
Tokenized deposits are digital representations of conventional commercial-bank deposits. Unlike privately issued stablecoins, they remain claims on regulated banks while adding blockchain capabilities such as programmability, conditional payments and automated settlement.
The pilots included two remortgage transactions in which funds were locked in a customer’s account and automatically released when the property transaction was completed. The system also tested a consumer marketplace payment in which money was released only after the purchased goods were exchanged. Reuters reported that the transactions were the first interbank transfers using tokenized deposits.
The transactions were executed on infrastructure developed by Quant, providing a shared platform through which tokenized deposits from different banks can move between institutions. The participating banks say interoperability is critical if tokenized commercial-bank money is to become a viable payments infrastructure rather than a collection of isolated bank systems.
The initiative is now moving toward broader applications. Further pilots are expected to test digital-asset settlement, linking tokenized customer money with blockchain-based assets to enable delivery-versus-payment transactions. Participating banks also plan to issue digital debt instruments that can be traded and settled using tokenized deposits. UK Finance said further pilots will demonstrate digital-asset settlement and tokenized debt instruments.
The development comes as central banks and financial institutions globally explore alternatives to stablecoins for blockchain-based settlement. Tokenized deposits offer a way to bring commercial-bank money onto digital networks while retaining the regulatory protections and banking relationships associated with traditional deposits.
The Bank of England has also been involved through its Synchronisation Lab, where the GBTD initiative is exploring how tokenized commercial-bank money could interact with central-bank money and support atomic settlement.
For Britain’s financial sector, the latest transactions represent a shift from proof-of-concept projects toward live, interoperable infrastructure for programmable money.
The next test will be whether the technology can move beyond pilots and support larger volumes of payments, digital securities and asset transactions across the UK’s banking system.
