Key Takeaways
- • The Bank of England has established a regulatory framework for sterling-denominated systemic stablecoins, permitting issuers to hold up to 60% of backing assets in short-term UK government debt, with an initial transitional requirement of 95% in government securities.
- • A temporary issuance guardrail caps each systemic stablecoin at £40 billion ($53 billion USD) initially, replacing previously proposed per-coin holding limits of £20,000 for individuals and £10 million for businesses; this guardrail will be regularly reviewed and removed once credit provision risks are addressed.
- • The regulatory regime applies exclusively to systemic stablecoins used for real-world payments and settlements, explicitly excluding non-systemic stablecoins used for buying and selling cryptoassets.
- • The Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 were enacted in February 2026, with the full regulatory regime scheduled to come into force in October 2027.
- • The Bank of England's forward-looking approach aims to support stablecoins as part of a "multi-money" system alongside commercial bank money and central bank money, while maintaining trust and financial stability.
Summary
The Bank of England has unveiled a comprehensive regulatory framework for sterling-denominated systemic stablecoins, designed to enable their use in real-world payments and settlements while safeguarding financial stability. The regime permits systemic stablecoin issuers to hold up to 60% of their backing assets in short-term sterling-denominated UK government debt, representing a significant softening from initially stricter proposals. During a transitional period, issuers must maintain up to 95% of reserves in short-term UK government securities, gradually reducing to the 60% threshold as risks to credit provision are mitigated.
The Bank has replaced previously consulted holding limits with a temporary issuance guardrail, capping each systemic stablecoin at £40 billion initially. This approach differs substantially from earlier proposals that would have imposed per-coin holding limits of £20,000 for individuals and £10 million for businesses. The guardrail will be subject to regular review and removal once the Bank determines that associated risks to credit provision have been adequately addressed.
Critically, the regulatory regime is narrowly tailored to systemic stablecoins with genuine payment and settlement applications. The Bank explicitly excludes non-systemic stablecoins used solely for cryptoasset trading from this framework, reflecting a distinction between payment-oriented innovations and speculative crypto markets. The Bank's stated mission is to ensure public trust in new forms of money by applying appropriate safeguards while enabling innovation.
The statutory foundation for this regime was established through the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026, enacted in February 2026. The full regulatory framework is scheduled to come into force in October 2027, providing market participants with an 18-month implementation window. The Bank of England's forward-looking approach reflects a deliberate policy to establish comprehensive rules before real-world stablecoin applications scale significantly, avoiding the regulatory challenges of retrofitting rules after widespread adoption.
