UK Banks Complete World’s First Interbank Tokenized Deposit Transactions for Remortgages and Marketplace Payments

Overview

On September 24, 2026, Barclays, NatWest, HSBC and several other UK lenders executed the world’s first interbank transactions using tokenized deposits. The trial marked a milestone in moving bank‑issued digital cash beyond a single institution’s ledger.

Transaction Details

The banks deployed the tokenized deposit infrastructure for two distinct use cases: settling remortgage agreements and conducting a marketplace‑payment test.

In the remortgage scenario, tokenized deposits were transferred between participating banks to finalize loan repayments, demonstrating that the digital cash could settle cross‑bank obligations.

The marketplace‑payment test involved a simulated purchase‑sale transaction on a digital commerce platform, with tokenized deposits serving as the settlement medium for the trade.

Implications

By completing interbank flows, the trial shows that tokenized deposits can operate across multiple banks’ ledgers, a step toward broader adoption of programmable bank money in the UK financial system.
