Bank of England Tests Stablecoins and Digital Pound in Cross-Border Trade

The Bank of England is taking another step in its exploration of digital money, with a new experiment examining whether stablecoins and a potential digital pound could work together in cross-border trade finance.

The project is being conducted through the Bank's Digital Pound Lab, an experimental environment designed to allow financial and technology companies to test potential use cases for digital payments.

The latest work focuses on a problem that has become increasingly important as financial institutions experiment with blockchain technology: how different forms of digital money can move through the same transaction without forcing businesses to rely on completely separate payment systems.

The experiment involves NOBO Finance, Dun & Bradstreet and Polygon Labs. One of the proposed scenarios would involve an exporter receiving an advance through a stablecoin while a UK importer completes the corresponding settlement using a simulated digital pound.

Importantly, this is not a live launch of a digital pound.

There are no real customers and no real funds involved in the testing environment. The Bank of England has also made clear that experimentation does not represent a decision to introduce a digital pound or an endorsement of any particular technology provider.

The distinction is important as governments and central banks around the world investigate how blockchain-based payment systems could fit alongside traditional financial infrastructure.

Bank of England Moves Digital Pound Research Forward

The Bank of England and HM Treasury have been studying the possibility of a digital pound for several years.

A digital pound would represent a potential new form of central bank money for households and businesses. Unlike a cryptocurrency, it would be issued by the central bank and would be designed to maintain the value of sterling.

But the project remains under consideration.

The Bank said in its March 2026 progress update that no decision had been made on whether to introduce a digital pound. The current design work is intended to help authorities determine whether such a system would provide meaningful benefits and how it could operate safely within Britain's payments infrastructure.

That makes the Digital Pound Lab particularly important.

Instead of immediately committing to a nationwide system, the Bank can use controlled experiments to examine individual technologies and payment scenarios.

The latest project takes that approach further by examining how a potential digital pound could interact with privately issued stablecoins.

Stablecoins Enter the Experiment

Stablecoins are digital assets designed to maintain a relatively stable value, generally by being backed by reserves or linked to an underlying currency.

The Bank of England itself describes stablecoins as a form of digital asset that can be used for payments and notes that they are already being used for cross-border transactions.

Their potential advantage in international commerce is speed.

Traditional cross-border payments can involve multiple financial institutions, messaging systems, currencies and settlement processes.

A transaction can therefore take time to complete and may involve significant administrative costs.

Blockchain-based payment systems could potentially reduce some of those steps.

But another problem emerges when different digital currencies or payment networks cannot communicate effectively.

A business could have access to a stablecoin, while another party requires settlement in central bank money.

The question then becomes whether the two forms of money can work together without creating additional delays or settlement risks.

That is precisely the issue the new experiment is designed to investigate.

A Cross-Border Trade Finance Scenario

The experiment centers on trade finance, an area where payment delays can have significant consequences for smaller businesses.

In a simplified version of the proposed scenario, an exporter could receive financing or an advance through a stablecoin-based payment rail.

The importer on the other side of the transaction could then settle its obligation using a simulated digital pound.

The goal is to determine whether both sides can participate in the same transaction without having to use identical forms of money.

Polygon Labs says its Open Money Stack will support the stablecoin settlement component, while the digital pound side will operate through the Bank of England's simulated environment.

The experiment is therefore less about replacing one currency with another and more about testing interoperability.

That could become increasingly important as the financial system develops multiple forms of tokenized money.

Why Interoperability Matters

The global financial system is already becoming more fragmented from a technological perspective.

Traditional bank deposits exist alongside stablecoins, tokenized deposits and other digital assets.

A potential central bank digital currency would add another form of digital money to that environment.

If each system operates independently, businesses could face a new version of the same problems that exist in traditional cross-border payments.

Money may be digital, but the infrastructure connecting different forms of money could still be slow.

The Bank of England has repeatedly emphasized the concept of a "multi-money" system in which different forms of sterling can coexist and remain interchangeable at equal value.

Its 2026 policy work on systemic stablecoins specifically discusses a future payments environment containing traditional bank deposits, tokenized deposits, regulated stablecoins and potentially a retail central bank digital currency.

The latest experiment fits directly into that broader vision.

The Role of Small and Medium-Sized Businesses

The project is not focused exclusively on payment speed.

NOBO Finance is also leading a separate workstream focused on creating what is described as an SME Bankable Profile.

The idea is to create a portable financial identity that could help smaller companies demonstrate their creditworthiness to potential lenders.

Dun & Bradstreet is contributing business and credit data, while blockchain infrastructure is being used to support the digital components of the system.

For small businesses, access to trade finance can be difficult.

Large companies often have established banking relationships, extensive financial histories and significant collateral.

Smaller businesses may have fewer resources and can face lengthy verification processes when attempting to secure financing.

A more portable digital credit profile could potentially make it easier for lenders to evaluate businesses across borders.

The experiment is therefore examining two related issues: how money moves and how information about the parties involved moves.

Both are important to international commerce.

Electronic Trade Documents Could Become Important

The project also involves digital trade documentation, including electronic bills of lading.

Bills of lading are important documents in international shipping because they provide information about goods being transported and can be connected to ownership and financing arrangements.

Moving such documents into digital infrastructure could allow trade finance transactions to become more automated.

Combined with smart contracts, a digital document could potentially trigger a payment or financing event once specified conditions have been satisfied.

This is one reason blockchain technology continues to attract interest from financial institutions.

The technology is not being examined simply because it creates digital currencies.

Its potential value may also lie in connecting payments, documents, identity and contractual conditions within a single digital process.

The Digital Pound Is Still Not a Reality

Despite the attention surrounding the experiment, consumers should not interpret the announcement as the arrival of a digital pound.

The Bank of England has repeatedly stressed that no final decision has been made to introduce one.

Its design phase continues to inform an assessment by the Bank and HM Treasury.

If the UK eventually decided to build a digital pound, legislation would also be required before it could be introduced.

That means there are still significant political, regulatory and technical steps between today's experiments and any future consumer-facing digital currency.

The current testing is about evidence.

Authorities want to understand what works, what does not work and what risks could emerge before deciding whether a nationwide system would be worthwhile.

No Real Customers or Money Are Involved

One of the most important details of the project is also one of the easiest to overlook.

The Digital Pound Lab is a simulated testing environment.

The Bank's own description of the Lab says it is intended to allow participants to develop and demonstrate use cases rather than operate a live financial system.

Polygon Labs likewise emphasized that the latest experiment uses no real customers and no real money.

That means the experiment does not test how consumers would actually use a digital pound in everyday life.

Instead, it tests whether the underlying technology and transaction logic could work.

This approach allows participants to identify technical problems without exposing real customers or financial institutions to the consequences of an unsuccessful experiment.

What the Bank of England Wants to Learn

The Bank's interest goes beyond determining whether a blockchain transaction can technically be completed.

The central bank must also consider financial stability, operational resilience, privacy, governance and regulatory requirements.

A payments system that works perfectly in a demonstration may still be unsuitable for national deployment if it cannot handle millions of transactions reliably.

The Bank's research into distributed ledger technology has already identified both potential benefits and challenges.

Its May 2026 DLT Innovation Challenge report noted that distributed ledger technology could potentially make financial processes faster and cheaper, while also highlighting questions around operational resilience, governance and settlement finality.

Those issues become particularly important when the technology is connected to money.

A payment system cannot simply be innovative.

It must also be dependable.

Stablecoins Are Receiving Greater Regulatory Attention

The timing of the experiment is significant because the UK is simultaneously developing a regulatory framework for stablecoins.

In June, the Bank of England published its policy statement and draft rules for systemic stablecoin issuers.

The framework is intended to establish safeguards for stablecoins that become widely used in payments and could therefore pose risks to financial stability.

The Financial Conduct Authority will regulate qualifying stablecoin issuance, custody and trading, while systemic stablecoins will fall under a joint regulatory framework involving the Bank and the FCA.

The Bank has said that stablecoins could provide benefits such as faster and cheaper payments, including cross-border transactions.

That makes experiments involving stablecoins and central bank money particularly relevant to the UK's broader payments strategy.

Public Money and Private Money

One of the biggest questions emerging from the experiment is how public and private forms of money should coexist.

A digital pound would be central bank money.

A stablecoin is privately issued digital money.

Traditional bank deposits represent another form of money created within the commercial banking system.

Tokenized bank deposits could create yet another version.

The Bank of England's vision is not necessarily that one form must eliminate the others.

Instead, policymakers are considering whether different forms can operate alongside each other while maintaining trust and reliable convertibility.

That approach could give businesses more choices.

It could also encourage competition among payment providers.

But it introduces a new technical challenge: ensuring that different forms of money can move between systems without creating friction.

What This Could Mean for Global Trade

If the technology eventually proves viable, cross-border trade could become one of the areas where digital money delivers its most tangible benefits.

Consider a small British importer purchasing goods from an overseas supplier.

Under today's system, the transaction can involve banks, payment processors, foreign exchange providers, shipping companies and trade-finance institutions.

Each participant may have its own systems and verification procedures.

A more integrated digital system could potentially connect some of those processes.

The payment could move faster.

Trade documents could be verified digitally.

Credit information could be shared with permission.

And smart contracts could automate certain conditions.

None of this means traditional financial institutions would disappear.

Instead, their roles could change as more of the underlying infrastructure becomes digital.

The Importance of Central Bank Settlement

The Bank of England continues to emphasize that central bank money has an important role in final settlement, particularly in wholesale financial markets.

That is one reason the interaction between stablecoins and central bank money is so important.

Stablecoins may offer flexibility and programmability, but central banks remain responsible for maintaining confidence in the monetary system.

The UK's proposed stablecoin framework reflects that concern.

The Bank has said systemic stablecoin issuers should ultimately be able to access payment systems directly and settle in central bank money, helping support timely redemption and reduce reliance on intermediaries.

The new experiment can therefore be viewed as part of a much larger question about how traditional central banking infrastructure should evolve as private digital money becomes more sophisticated.

It Is Not an Endorsement of Polygon

Polygon's participation has attracted attention because the blockchain company is providing infrastructure for part of the experiment.

But participation should not be confused with official selection.

Polygon itself explicitly states that its involvement does not represent Bank of England endorsement of its technology or products.

Nor does the experiment establish what the final architecture of a digital pound would look like.

That distinction is important.

Central banks frequently work with technology companies during research projects without committing to those companies for eventual production systems.

The purpose is to learn.

A Broader Shift in Financial Infrastructure

The latest experiment illustrates how blockchain technology is gradually moving beyond cryptocurrency trading.

For years, much of the public discussion around blockchain centered on Bitcoin, Ethereum and speculative digital assets.

Financial institutions are increasingly exploring a different question.

Can the underlying technology make existing financial processes faster, more transparent and easier to automate?

Trade finance is one area where the answer could potentially be meaningful.

The industry handles enormous volumes of international transactions, many of which still depend on documents, intermediaries and complex coordination.

Digitizing those processes could potentially unlock efficiencies without requiring businesses to abandon traditional currencies entirely.

The UK Is Building a Multi-Money Future

The Bank of England's approach suggests that the UK's future payment system may not revolve around a single digital currency.

Instead, the country is exploring a network in which several forms of money coexist.

Bank deposits could remain central to everyday payments.

Stablecoins could provide additional options for certain transactions.

Tokenized deposits could emerge within financial markets.

And a digital pound could eventually provide a form of central bank money for the digital economy.

The challenge is ensuring that these systems remain interoperable.

That is the significance of the latest Digital Pound Lab experiment.

What Happens Next

The current experiments are expected to contribute to the Bank of England and HM Treasury's broader assessment of the digital pound.

The Bank's Digital Pound Lab was scheduled to operate through July 2026, with Phase 2 focused on innovative payment use cases developed by participating organizations.

The latest announcement from Polygon and its consortium partners provides a new example of the type of experimentation being conducted as the program reaches the end of that testing period.

The findings will not automatically lead to a consumer digital pound.

Instead, they will provide policymakers with more evidence about what the technology could accomplish and what safeguards would be necessary.

The Bank has said it expects to complete its design work and publish an assessment later in 2026 alongside its decision on next steps.

Why the Experiment Matters

The significance of the latest test is not simply that Britain is exploring another form of digital currency.

The bigger issue is interoperability.

The financial system is moving toward a world in which money can exist in several digital forms.

Stablecoins are already being used.

Tokenized assets are being developed.

Central banks are exploring digital currencies.

Commercial banks are experimenting with tokenized deposits.

The systems created during this transition will need to communicate with each other.

If they cannot, digital money could reproduce many of the same inefficiencies found in today's fragmented financial infrastructure.

If they can, cross-border transactions could potentially become faster, more programmable and easier to automate.

The Bank of England's latest experiment is an attempt to understand which of those possibilities is realistic.

Conclusion

The Bank of England's Digital Pound Lab is testing an increasingly important question for the future of money: can stablecoins and central bank digital money operate together within the same financial transaction?

The latest Phase 2 experiment involving NOBO Finance, Dun & Bradstreet and Polygon Labs focuses on cross-border trade finance, with a simulated transaction in which an exporter could receive a stablecoin advance while a UK importer completes settlement using a simulated digital pound.

The experiment also explores portable credit profiles for small and medium-sized businesses and the potential use of digital trade documentation and smart contracts.

But the project remains firmly in the testing stage.

There are no real customers and no real funds involved, and participation does not mean the Bank of England has selected a particular technology or committed to launching a digital pound.

The broader significance is nevertheless substantial.

Britain is preparing for a financial environment in which traditional bank money, stablecoins, tokenized deposits and potentially central bank digital currency could coexist.

The challenge will be making those forms of money interoperable while preserving stability, privacy, regulatory oversight and public confidence.

For businesses involved in international trade, the potential benefits could be considerable if these experiments eventually translate into real-world infrastructure.

For policymakers, however, the priority is likely to remain the same: understand the technology first, identify its risks and only then decide whether it belongs in the financial system at scale.

The digital pound may still be years away from becoming a reality, but the infrastructure and policy discussions surrounding it are already reshaping the debate over what money could look like in the next generation of global payments.
