The UK’s financial sector has taken a significant step forward in exploring the future of digital finance, as UK Finance—the country’s leading financial trade association—announced the successful completion of the experimental phase of a tokenization and central bank digital currency (CBDC) platform. The initiative, known as the Regulated Liability Network (RLN), brought together 11 major financial institutions, including Barclays, Citi UK, HSBC, and NatWest, to test a next-generation financial infrastructure designed to modernize payments and settlements.
This trial marks a pivotal moment in the UK’s journey toward a digitized financial ecosystem, demonstrating tangible improvements in economic value, operational efficiency, and programmable payment functionality.
The Regulated Liability Network: A Foundation for Financial Innovation
At its core, the RLN is a proposed financial market infrastructure that enables secure, interoperable transactions using tokenized assets and simulated CBDCs. The platform was built as a multi-issuer tokenization system, allowing commercial banks to issue tokenized commercial bank deposits—digital representations of traditional fiat held in bank accounts. These tokens can be transferred instantly across institutions with built-in programmability features.
Simultaneously, the network simulated a wholesale CBDC, a form of central bank-issued digital currency intended for use by financial institutions rather than retail consumers. This dual-layered design allows for seamless integration between private-sector money (bank deposits) and public-sector digital currency (CBDC), creating a unified environment for settlement and clearing.
A key technical component of the RLN was its API layer, which ensured interoperability across existing ledgers and payment systems. This means legacy banking infrastructures can connect with the new platform without requiring full-scale overhauls—reducing friction and accelerating adoption.

Key Findings from the Experimental Phase
The trial yielded several promising outcomes:
- Enhanced economic value: The platform demonstrated potential cost savings and increased transaction efficiency across multiple financial processes.
- Programmable payments: Smart contract capabilities enabled conditional transactions—such as automatic payouts upon fulfillment of predefined criteria—opening doors for innovations in payroll, supply chain finance, and regulatory compliance.
- Improved settlement finality: Near-instant settlement reduced counterparty risk and liquidity constraints.
- Regulatory alignment: The UK’s legal framework was found to be sufficiently adaptable to support such innovations, provided ongoing collaboration between regulators and industry stakeholders.
Peter Left, co-chair of the RLN Project, emphasized the collaborative nature of the experiment:
“Working in partnership, we have demonstrated how this platform supports developments in money and payments aligned to common public and private sector objectives, while also providing clear and long-term customer and industry benefits.”
Industry Momentum Behind Tokenization
The RLN trial reflects broader momentum within the UK’s financial sector toward embracing asset tokenization—the process of converting real-world assets (RWAs), such as bonds, equities, or real estate, into digital tokens on a blockchain. This transformation enhances liquidity, reduces settlement times, and enables fractional ownership.
In 2023, the Financial Conduct Authority (FCA) endorsed an industry-led report advocating for the tokenization of investment funds, signaling strong regulatory support. Earlier in 2024, the newly elected Labour government outlined ambitions to position the UK as a global securities tokenization hub, further reinforcing national commitment to digital finance innovation.
These developments suggest that the UK is strategically positioning itself at the forefront of the tokenized economy—one where traditional finance converges with decentralized technologies to unlock new efficiencies and services.
Regulatory Readiness and Future Roadmap
One of the most encouraging findings from the RLN experiment was the assessment that the UK’s current legal and regulatory framework is flexible enough to accommodate a “platform for innovation.” However, UK Finance stressed that sustained engagement with regulators—including the Bank of England and HM Treasury—will be essential to move from experimentation to implementation.
Future phases may involve live pilots with regulated entities, deeper integration with existing payment systems like CHAPS and Faster Payments, and expanded use cases in trade finance and cross-border remittances.

Frequently Asked Questions (FAQ)
Q: What is the Regulated Liability Network (RLN)?
A: The RLN is an experimental financial infrastructure developed by UK Finance and member banks to explore tokenized bank deposits and wholesale central bank digital currencies (CBDCs). It aims to improve payment efficiency, enable programmable money, and support innovation in financial services.
Q: Which banks participated in the RLN trial?
A: Eleven member institutions took part, including Barclays, Citi UK, HSBC, and NatWest. The project also involved professional services firms to assess technical, legal, and regulatory aspects.
Q: Is this related to a retail digital pound?
A: No. The RLN focused on wholesale CBDCs for use between financial institutions. A retail digital pound—for everyday consumer use—is being explored separately by the Bank of England.
Q: What are programmable payments?
A: These are payments embedded with logic (via smart contracts) that execute automatically when certain conditions are met—such as releasing funds only after delivery confirmation in a supply chain.
Q: Could this system replace traditional banking infrastructure?
A: Not immediately. The RLN is designed to complement existing systems, offering interoperability so banks can innovate without abandoning legacy platforms.
Q: When will this technology go live?
A: There is no official launch date yet. The project remains in development, with further testing and regulatory consultation expected before any deployment.
Strategic Implications for the UK Financial Sector
The success of the RLN trial underscores a growing consensus: digital transformation in finance is no longer optional—it’s inevitable. By investing in tokenization and CBDC research now, the UK is laying the groundwork for a more resilient, efficient, and inclusive financial system.
Moreover, early leadership in this space could attract global capital, foster fintech innovation, and strengthen London’s status as a leading international financial center—even as competition intensifies from jurisdictions like Singapore, Switzerland, and Hong Kong.
As institutions continue refining these platforms, one thing is clear: the line between traditional finance and digital asset ecosystems is rapidly blurring.

Conclusion
The Regulated Liability Network experiment represents more than just a technical trial—it’s a strategic signal of intent from the UK’s financial industry. With strong participation from top-tier banks, regulatory openness, and demonstrated benefits in efficiency and functionality, the path toward a modernized financial infrastructure is becoming clearer.
While challenges remain—particularly around scalability, cybersecurity, and cross-border coordination—the foundation has been laid. The next phase will require continued collaboration between policymakers, regulators, and private-sector players to turn vision into reality.
For investors, innovators, and institutions alike, the message is clear: the future of finance is being built now—and it’s tokenized.
