Legal Payment Tender Risks in the United Kingdom
Ensuring Currency Security and Preventing Counterfeiting
Executive Summary
The Bank of England's Prudential Regulation Authority (PRA) has released its Business Plan for 2025-26, highlighting key areas of focus related to payment systems, digital money, and the security of legal tender in the United Kingdom. This analysis explores the emerging risks to the UK's monetary system, the regulatory measures being implemented to preserve the value and security of legal payment tender, and strategies to prevent counterfeit currency from gaining traction in illegal payment settlements.
Key Risk #1
Digital disruption of traditional monetary systems
Key Risk #2
Advanced counterfeiting technologies
Key Risk #3
Liquidity challenges during payment system transitions
Current Landscape of Legal Tender in the UK
The concept of legal tender in the UK centers around the official currencyâBank of England notes and Royal Mint coinsâas the legally recognized medium for settling debts. As of May 2025, the UK faces several challenges in maintaining the integrity of its currency system.
- Digital Transformation of Money: The rapid evolution of digital payment systems and cryptocurrencies is changing how transactions occur, potentially threatening the primacy of traditional legal tender.
- Counterfeiting Threats: Advanced printing and reproduction technologies have made sophisticated counterfeiting operations more accessible, increasing the risk of fake currency entering circulation.
- Economic Uncertainty: Post-pandemic economic pressures, combined with global trade tensions, have created conditions where alternative or illegal payment methods might gain appeal.

Key Regulatory Developments from the PRA Business Plan 2025-26
Future of Payments Initiative
The Bank of England is continuing its work on innovation in money and payments, with a particular focus on monitoring developments in deposit takers' innovation in deposits, e-money, and stablecoins. This builds upon guidance provided in their 2023 Dear CEO letter and will remain a priority throughout 2025.
Cryptoasset Regulation
The PRA is developing policy to implement the Basel Committee on Banking Supervision (BCBS) standard on banks' cryptoassets exposures in the UK. This regulatory framework aims to establish clear boundaries between traditional legal tender and digital assets, ensuring that cryptoassets do not undermine the stability of the established monetary system.
The PRA continues to engage with international partners to assess developments in digital money and cryptoasset markets.

Liquidity Framework Changes
Following the events of March 2023, which saw significant deposit outflows from institutions like Silicon Valley Bank and Credit Suisse, the PRA has implemented changes to how firms access sterling central bank reserves. In 2025, the Bank's operating framework will transition to a demand-driven repo-led framework, with the stock of sterling reserves determined by firms' borrowing rather than by extraordinary monetary policy operations.
Digital Pound Development
The Bank of England is advancing its work on a potential central bank digital currency (CBDC), the "digital pound," which would serve as an official digital complement to physical banknotes. This initiative aims to ensure that the Bank maintains monetary sovereignty in an increasingly digital financial landscape while offering a secure alternative to private digital currencies that might otherwise challenge the primacy of legal tender.
Counterfeit Prevention Measures
To combat counterfeiting and protect the integrity of UK legal tender, several measures are being implemented or enhanced:
- Advanced Security Features: The Bank of England continues to develop and deploy cutting-edge security features in banknotes, making them increasingly difficult to counterfeit. The polymer notes introduced in recent years include multiple layers of security that remain at the forefront of anti-counterfeit technology.
- Enhanced Detection Systems: Financial institutions are being encouraged to implement more sophisticated counterfeit detection systems at points of deposit and withdrawal.
- International Cooperation: The PRA is strengthening its domestic and international relationships to ensure effective regulation and supervision across borders, particularly important for tackling organized counterfeiting operations that often operate transnationally.
- Public Education: Ongoing campaigns to educate retailers, businesses, and the public about security features and how to identify counterfeit currency remain crucial to preventing fake currency from gaining acceptance in day-to-day transactions.

Critical Third Party (CTP) Regime Implementation
The Financial Services and Markets Act 2023 gave HM Treasury the power to designate certain third-party service providers as 'critical' to the UK financial system. This new Critical Third Party (CTP) regime will have significant implications for payment processing and currency handling services, allowing regulators to ensure that entities crucial to the movement and security of legal tender maintain appropriate standards and safeguards.

Risk Assessment and Outlook
The risk to legal tender in the UK operates on multiple levels, from immediate concerns to long-term strategic considerations:
Short-term Risks (1-2 years)
- Counterfeit Detection Gaps: As businesses adjust to new banknote designs and security features, there may be a temporary window where detection capabilities lag behind counterfeiting techniques.
- Payment System Disruptions: The transition in the Bank's operating framework for supplying sterling reserves could create short-term liquidity challenges for some financial institutions.
Medium-term Risks (3-5 years)
- Competition from Stablecoins: Privately issued stablecoins could gain significant adoption, potentially challenging the primacy of official currency for certain transaction types.
- Cross-border Payment Evolution: Changes in international payment systems could create regulatory gaps that might be exploited for illicit transactions using counterfeit or unofficial currencies.
Long-term Strategic Considerations
- Digital Pound Implementation: The successful rollout of a CBDC will be crucial to maintaining the relevance of official legal tender in an increasingly digital economy.
- Regulatory Harmonization: International alignment of regulations governing digital assets and payment systems will be essential to prevent regulatory arbitrage that could undermine UK monetary sovereignty.

Conclusion
The Bank of England's PRA Business Plan 2025-26 demonstrates a comprehensive approach to protecting the status and security of legal payment tender in the UK. By addressing both traditional counterfeiting threats and emerging digital challenges, the Bank aims to ensure that official UK currency remains the secure, trusted, and valued medium of exchange throughout the economy.
Financial institutions, payment service providers, and businesses handling currency should pay close attention to the evolving regulatory framework and take proactive measures to enhance their anti-counterfeiting capabilities and ensure compliance with the emerging rules governing both physical and digital money.
