Britain’s largest banks have completed what UK Finance described as the world’s first interbank transactions using tokenized deposits, moving blockchain-based commercial bank money across two remortgages and a simulated person-to-person marketplace payment. The milestone, announced Sep. 24, is the most concrete result yet of the Great British Tokenised Deposit initiative.
Who did what
Lloyds Banking Group, NatWest and Barclays carried out two remortgage transactions using tokenized deposits, while a separate group of three banks that included HSBC tested a person-to-person payment linked to a simulated online marketplace purchase. The wider pilot counts Barclays, HSBC, Lloyds, NatWest, Nationwide and Santander as participants, with Quant, EY and Linklaters supporting the initiative.
The distinction from earlier projects is interoperability. Banks have spent years experimenting with blockchain systems for deposits, bonds and other assets, but most of that work ran inside each institution’s own infrastructure. That siloed approach limited the usefulness of tokenized deposits whenever money needed to move between customers of different banks, which is to say, in almost every real payment. UK Finance designed this pilot specifically around interbank movement, and the latest transactions put that model into practice.
How the transactions worked
For the online marketplace test, programmable deposits allowed money to remain reserved in a buyer’s bank account until the agreed conditions of the transaction were met. Funds were released to the seller only after confirmation that the goods had been received. No physical goods changed hands because the transaction was simulated, but the payment logic itself ran end to end.
A similar mechanism governed the two remortgages. Funds were locked during the property process and released automatically when the transaction completed. Jana Mackintosh, UK Finance’s managing director for Payments and Innovation, said the setup showed how programmable deposits could lower fraud risks in online transactions, since sellers cannot run off with money before conditions are satisfied.
The remortgage use case had been built into the project from its earlier stages, alongside person-to-person marketplace payments and settlement of digital assets. Property transactions are a deliberate choice for a first test: they are high value, fraud-sensitive, and involve long chains of intermediaries where funds traditionally sit in escrow for days. Conditional release of tokenized deposits compresses that process while keeping the money inside regulated banks throughout.
Why tokenized deposits are not stablecoins
Tokenized deposits represent conventional commercial bank deposits recorded on a blockchain or another distributed ledger. The money remains a liability of the bank that issued it and retains the legal status and regulatory protections attached to an ordinary deposit. That is the key difference from stablecoins, which are generally issued by private companies against reserves and create a separate claim on the issuer.
The Bank of England has encouraged banks to experiment with tokenized deposits while leaving room in its digital money framework for regulated stablecoins as another payment form. Deputy Governor Sarah Breeden said in May that the central bank wants a system in which traditional deposits, tokenized bank deposits, regulated stablecoins and potentially a retail central bank digital currency can operate alongside each other. The UK pilot is effectively the banking sector building its corner of that system.
What comes next
UK Finance plans to establish a company and governance framework for the project, giving the initiative a permanent structure rather than a series of experiments. Three digital bonds are due to be issued and settled using tokenized deposits in early 2027, extending the work from payments into capital markets settlement.
The UK results arrive amid a busy stretch for tokenized deposit pilots elsewhere. Canadian banks have tested shared interbank tokenized deposits, United States banks have run cross-border trials over shared ledger infrastructure, and institutions including Citi, DBS and HSBC have completed live tokenized deposit transactions through the Swift ledger adapter. The differentiator claimed by UK Finance is first interbank movement covering conventional banking use cases, remortgages and marketplace payments, rather than abstract settlement tests.
The bigger picture
The pilot’s message is that the large incumbent banks have not ceded onchain money to crypto issuers. By keeping tokenized deposits inside the banking system, with deposit protections intact, UK lenders are betting that programmability can be added without changing what a bank deposit fundamentally is. If the 2027 bond issuances land as planned, Britain will have a working template for moving commercial bank money on shared infrastructure at scale.
There are open questions. Governance of the new company structure, the ledger or ledgers selected for production use, and how non-participating banks join later all remain to be settled. Regulators will also want clarity on how tokenized deposits interact with deposit insurance and resolution regimes if a participating bank fails mid-transaction. UK Finance has acknowledged that the governance framework being established is meant to answer exactly those questions before the 2027 bond issuances arrive.

remortgages make sense as the test case, the redemption float on a property chain is exactly where tokenized deposits shine. now get me a solicitor that answers email
two actual remortgages moved on tokenized deposits, not a sandbox demo. that is the headline people are skipping
Agree, though the P2P leg was only a simulated marketplace purchase. Half real, half rehearsal.
lloyds, natwest and barclays settling remortgages across banks is genuinely new. this is what interop actually looks like instead of another bank-only pilot
ok but one of the three was a simulated marketplace payment. wake me up when a real P2P transfer clears between two different banks
you scrolled past the two remortgages then. cross bank property settlement with real money is strictly harder than a P2P coffee split
the remortgages were real though. two actual property transactions cleared across different banks, that half you cant wave away
the simulated P2P part is fair to dunk on but the remortgages were real money moving across lloyds, natwest and barclays rails. wake up call already rang
real money moving is fair, but two remortgages is a pilot not a rail. call me when nationwide clears one without a sandbox waiver
two real remortgages settled cross bank beats a thousand hypothetical payments. property settlement is where the actual money sits
remortgages are the killer use case because the money is huge and the settlement pain is real. two cross bank property deals beats a thousand coffee payment demos
fair, but two real remortgages beat zero real anything. the p2p leg shows up once the float lobbyists lose
meanwhile my bank still takes 3 days for a sepa transfer. love watching six of them crack interbank settlement first
That is the point though. This is exactly the tech that kills the 3 day window eventually.
SEPA is instant across most of the EU now, the delays are your bank holding the float. tokenized deposits attack exactly that float, that is why the big six care
the float is the entire business model for mid tier banks, they will fight tokenized deposits harder than they fought open banking. watch the lobbying around this, that is where resistance shows up
open banking took a decade of bank lobbying and still landed. float income is real but regulatory momentum on settlement is one directional now
Quant doing the plumbing again and nobody notices. They have been attached to every serious UK institutional chain project for a decade.
quant on plumbing, linklaters on legal, ey on process. this is what production infrastructure looks like. no token, no airdrop, no press tour
nationwide and santander are in the pilot but not the first transactions, that says a lot. the big four prove the rails then everyone else plugs in
nationwide and santander waiting on the sidelines is the standard big four risk dance. someone else breaks the glass first
big four go first is textbook. nationwide plugs in once the remediation paperwork from someone elses migration clears, then it snowballs
six big uk banks plus quant and ey on interbank tokenized deposits while the US argues about stablecoin bills. the plumbing race is quietly being won on remortgage paperwork of all things
interbank tokenized deposits clearing while sepa still takes three days in practice. the uk quietly took the plumbing lead here
two remortgages clearing across different banks is the part that matters. property settlement is where the pain, and the fees, actually live
