Bank Deposits Just Learned to Move Like Tokens

Seven of Britain’s largest banks moved real customer money as blockchain tokens this week, not in a lab but in production. Barclays, HSBC, Lloyds Banking Group, Monzo, Nationwide, NatWest and Santander completed live transactions under UK Finance’s Great British Tokenised Deposit initiative, the first time a tokenised bank deposit has crossed from one major UK institution to another and settled as legal tender rather than a simulation.

What actually happened

Lloyds, NatWest and Barclays carried out two live remortgage payments using tokenised deposits, moving money between the banks involved in each transaction on a shared ledger instead of through the usual correspondent rails. Separately, a group of three banks including HSBC ran a customer-to-customer payment that simulated a purchase on an online marketplace, the kind of transaction where fraud and delayed settlement are both common complaints.

The work sits under UK Finance’s Regulated Liability Network project, and this phase carries its own name: the Great British Tokenised Deposit initiative, or GBTD. Quant supplied the technology layer, with EY and Linklaters advising on the business case and legal structure respectively.

Why a tokenised deposit is not a stablecoin

A tokenised deposit is an ordinary bank deposit represented on a shared ledger instead of a bank’s internal core system. The money stays a liability of the issuing bank and keeps the legal status and protections of a normal deposit, including deposit insurance. That is the opposite design choice from a stablecoin, which is typically issued by a non-bank against a reserve of assets and carries no equivalent guarantee. Banks have spent the last two years worried that stablecoins would pull deposits off their balance sheets; tokenising the deposit itself is their answer, keeping the liability on the bank’s books while giving it some of the programmability that makes stablecoins attractive.

The slow road to this week

UK Finance’s Regulated Liability Network work began in November 2022 and moved through a 2024 experimentation phase involving Barclays, Citi, HSBC, Lloyds, Mastercard, NatWest, Nationwide, Santander, Standard Chartered, Virgin Money and Visa, which tested programmable payments and the locking and unlocking of funds without moving real customer money. This week’s transactions are the first time the project has handled live payments rather than test cases, and the pilot is scheduled to run until mid-2026 before UK Finance decides what, if anything, becomes permanent infrastructure.

Jana Mackintosh, managing director at UK Finance, framed the milestone as a collective effort rather than a single bank’s product launch. “This project is a powerful example of industry collaboration to deliver next generation payments for the benefit of customers and businesses,” she said. Ryan Hayward, head of digital assets at Barclays, tied the work directly to defending banks’ core product: “The upgrading of bank deposits to a digital form will help to ensure that commercial bank money remains central to the economy.”

The two use cases banks actually tested

The remortgage payments matter because property transactions are exactly where slow settlement costs money: a chain of buyers and sellers can be held up for days waiting for funds to clear between banks, and every day of delay carries legal and interest-rate risk for someone in the chain. Moving that leg of the transaction onto a shared ledger, where the banks involved can see the token settle rather than wait for a message to confirm it, is a direct attack on that delay.

The marketplace payment is aimed at a different problem: fraud in peer-to-peer transactions, where a buyer pays a stranger for goods that may or may not arrive. Paul Horlock, chief payments officer at Santander UK, described the ambition in terms of consumer confidence rather than settlement speed, pointing to “the opportunity for ‘smart money’ to retail consumers to provide increased confidence and security.” Isabel Pitt, deputy payments director at Nationwide, was more cautious about what the pilot proves today: “We’re excited by what tokenised deposits could potentially mean for customer experience in the future,” a description that reads as promise rather than delivered product.

Gilbert Verdian, chief executive of technology partner Quant, framed the milestone in infrastructure terms rather than product terms: “This milestone goes beyond improving payments, it’s about enabling new forms of programmable money.” That is the more ambitious claim in the room, and it is also the one this pilot has not yet tested. Two remortgages and a simulated marketplace purchase demonstrate that tokenised deposits can move between banks at all; they do not yet demonstrate the programmable use cases, such as funds that release automatically when a contractual condition is met, that would justify Verdian’s framing.

What it means for the finance leader

The interesting problem here was never tokenising one bank’s ledger. Any single institution can already do that internally. The hard part is getting seven competing banks’ tokenised ledgers to recognise and settle each other’s tokens, which is the actual test this pilot is running. If it works at scale, treasury and payments teams gain a settlement rail that moves at blockchain speed but never leaves the regulatory perimeter of ordinary bank deposits, which matters for any finance leader who has been asked to explain stablecoin exposure to a board or an auditor.

It also raises the bar for banks not participating. Seven of the UK’s largest retail and commercial banks now have a working answer to “how do we compete with stablecoin rails without giving up deposit funding,” and smaller banks and building societies will eventually need either access to this network or a credible alternative.

What to watch

Two things determine whether GBTD becomes real infrastructure or another well-documented pilot. First, whether the interoperability actually holds once transaction volume rises past a handful of remortgages and test purchases. Second, whether UK Finance opens participation beyond the current seven banks before the pilot ends in mid-2026, since a members-only settlement network defeats much of the point. The project also feeds into the UK government’s broader digital-money ambitions, including its plans for digital gilts, so a credible outcome here has consequences well beyond the participating banks’ own balance sheets.
