Banks are finding practical uses for blockchain, but their goal is not to turn every customer into a cryptocurrency user. They are testing whether ordinary bank deposits can move more efficiently when payments involve several institutions or depend on specific conditions. The aim is to speed up settlement and reduce delays without sacrificing traditional banking protections.
On September 24, 2026, UK Finance announced the first live customer transactions under its Great British Tokenized Deposit (GBTD) project. Seven banks took part: Barclays, HSBC UK, Lloyds Banking Group, Monzo, Nationwide, NatWest and Santander.
During the trials, banks completed two mortgage refinancing payments and one online marketplace payment. Rather than releasing the money immediately, they held the funds until both sides met the agreed requirements. Once the conditions were confirmed, the banks released the payments.
While blockchain is not new to banks, using it this way represents a different approach to payment processing. It allows banks to coordinate payments on a shared platform, automate conditional transfers and potentially reduce manual checks.
Why Banks Prefer Tokenizing Existing Deposits
Tokenized deposits let banks use digital technology for payments while customers keep their money in regular bank accounts. Stablecoins work differently: private entities issue these tokens, typically backed by reserves intended to support their value.
Tokenized deposits may also appeal to banks for financial reasons. Customer deposits are an important source of funding for loans and other services. If customers move substantial amounts of money into stablecoins instead, banks could face pressure on their deposit base and funding costs, although the impact would depend on the scale of adoption and how the stablecoins are held.
The UK trials demonstrated how banks could use tokenized deposits in specific transactions. During two remortgage payments, banks held the funds and released them once the required conditions were met. Meanwhile, the marketplace trial tested how buyers could release payments after receiving their goods. These approaches could help reduce delays and payment disputes, although the trials alone do not establish how effectively the systems would perform at scale.
Banks would still need to verify that each transaction meets its conditions. Blockchain can release funds automatically, but it cannot independently determine whether a property deal has legally closed or a seller has delivered the goods. Those conditions depend on reliable information from the parties and systems involved.
Tokenized Deposits and Stablecoins May Serve Different Needs
Tokenized deposits may be well suited to payments within the regulated banking system. However, international transfers present additional challenges. Different currencies, banking rules and settlement networks complicate cross-border transactions. Stablecoins may offer advantages in some situations, particularly when institutions need to transfer funds outside normal banking hours.
On September 30, 2026, Lloyds Banking Group reported a seven-day trial with Visa. The bank settled $750,000 in payment obligations using USDC stablecoins. Funds reached Visa in less than an hour, including over the weekend. Lloyds participated in both initiatives, illustrating how a bank can explore different forms of digital money rather than committing exclusively to one approach.
The Bank of England has also discussed a system in which different forms of money could operate alongside one another. In a speech on May 19, 2026, Deputy Governor Sarah Breeden outlined a future in which traditional deposits and tokenized deposits coexist with regulated stablecoins. The central bank is looking at how these payment instruments could be made easier to exchange, reducing friction for customers. A key challenge is ensuring that separate networks can communicate and settle transactions reliably.
Banks Must Now Prove Blockchain Can Work at Scale
The British trials demonstrated that tokenized deposits can be used in a small number of live customer transactions. However, three transactions are not enough to establish that the technology will remain efficient, reliable or cost-effective across millions of payments.
Banks must still address operating costs, cybersecurity, legal certainty and compatibility between payment networks. They also need systems that can handle mistakes and technical failures.
Meanwhile, UK Finance plans further trials involving digital debt instruments and settlement using tokenized deposits. The wider banking industry is exploring similar applications. On July 30, 2026, Lloyds reported three live tokenized deposit transactions through Project Agorá. These involved sterling, euros and Swiss francs, including a transaction connecting currency conversion, payment and settlement.
These trials show that blockchain could help banks handle certain payments in new ways. However, banks still need to demonstrate that these systems offer practical advantages over the infrastructure they already use. They must also account for the costs and complexity of introducing new technology.
The potential market is substantial, although estimates need to be interpreted carefully. The International Monetary Fund (IMF), in its October 2026 Global Financial Stability Report, estimated that publicly tokenized real-world assets (RWAs) were worth approximately $65 billion as of July 31, 2026. The report also discussed the scale of global capital markets, which hold assets measured in the hundreds of trillions of dollars. These figures describe different measures and should not be treated as a direct forecast of how much capital will migrate to tokenized assets. The IMF also noted that limited liquidity and fragmented trading environments could hinder broader adoption.
Banks may eventually use stablecoins for some purposes while continuing to rely on tokenized deposits for others. Tokenized deposits could support payments within the banking system, while stablecoins may offer greater flexibility for certain cross-border transfers. Which approach proves most useful will depend on cost, regulation, interoperability, risk management and the needs of individual customers.
