The United Kingdom has unveiled its final regulatory framework for systemic stablecoins, introducing a £40 billion issuance cap and assigning the Bank of England a new secondary objective to foster innovation in digital payments. The regime takes effect on October 25, 2027, as London races to keep pace with the EU’s MiCA and the US GENIUS Act.
🔑 Key Takeaways
- The Bank of England receives a new secondary statutory objective to support innovation in stablecoins and digital payments.
- A temporary issuance cap of £40 billion (~US$52.8 billion) per systemic stablecoin replaces the previously proposed individual holding limits.
- Up to 70% of reserves may be held in short-term UK government debt, with the balance in non-interest-bearing BoE deposits.
- The regime enters into force on October 25, 2027; authorization applications open from September 30.
- The global stablecoin market now stands at $303 billion, up from $200 billion a year earlier, according to DeFiLlama.
A new innovation mandate for the Bank of England
The UK government has announced an amendment to the Financial Services and Markets Bill to add a new secondary statutory objective to the Bank of England’s remit: supporting innovation in stablecoins and digital payments. Financial stability remains the institution’s primary mission, but the BoE will now be required to report annually to Parliament on its progress in payments and digital money innovation.
City Minister Lucy Rigby framed the move as a clear political signal:
« While financial stability will always remain the Bank’s primary objective, this secondary objective will support the Bank in its ongoing work to promote innovation in payments and digital finance, ensuring the UK remains a global leader in financial services. »
Lucy Rigby, City Minister
Issuance cap and reserve requirements
At the heart of the framework sits an unprecedented issuance cap. UK authorities have abandoned the previously proposed holding limits (£20,000 per individual and £10 million per company), deemed too restrictive by industry. In their place, a temporary issuance ceiling of £40 billion (around US$52.8 billion) per systemic stablecoin has been introduced.
Described as a « temporary issuance guardrail, » the cap will be reviewed regularly. The BoE intends to loosen and eventually remove it once risks to credit provision have been effectively mitigated. Reserve composition is also tightly defined:
- Up to 70% in short-term UK government debt (gilts), up from an initially proposed 60%.
- At least 30% in non-interest-bearing deposits at the Bank of England, ensuring liquidity for redemptions.
| Parameter | Initial proposal | Final framework |
|---|---|---|
| Individual holding limit | £20,000 per person | Removed |
| Corporate holding limit | £10M per company | Removed |
| Issuance cap | None | £40B per systemic stablecoin |
| Government debt in reserves | 60% | 70% |
| BoE deposits | 40% | 30% (non-interest-bearing) |
Sasha Mills, Executive Director for Financial Market Infrastructure at the BoE, noted that systemic stablecoins must meet the same standards as existing forms of money used in the real UK economy. The Bank for International Settlements (BIS), in a dedicated chapter of its 2026 Annual Economic Report, struck a more cautious tone, warning that stablecoins « fall short on key properties of money and have structural flaws » and that their « widespread adoption could affect macroeconomic and financial stability. »
Implementation timeline
The UK regime will roll out on a multi-year schedule, in coordination with the Financial Conduct Authority (FCA):
- September 30: issuer authorization applications open.
- September 22: deadline for industry feedback on the proposal’s practicability.
- End of 2026: expected publication of the final code of practice.
- October 25, 2027: regime enters into force for systemic stablecoins.
The BoE and FCA are working together to deliver an end-to-end framework, including transition arrangements for firms moving from non-systemic to systemic status.
Mixed industry reaction
UK industry players responded along divergent lines. Janine Hirt, CEO of Innovate Finance, welcomed some adjustments while criticizing the framework’s overall rigidity:
« Despite some positive changes in response to industry feedback, the Bank of England’s approach still risks creating the most conservative and cautious stablecoin regime in the world. »
Janine Hirt, CEO of Innovate Finance
She warned that the issuance cap could « hamper UK tokenisation projects in wholesale capital markets and create instability if demand exceeds supply, » and noted that the requirement to hold 30% of reserves at the BoE « removes a third of potential revenue for service providers and issuers. »
By contrast, the co-chairs of the Crypto and Digital Assets All-Party Parliamentary Group, Lord Ed Vaizey and MP Gurinder Singh Josan, welcomed the removal of individual holding limits as « a significant and positive step for the UK’s digital assets sector » and « a clear signal that the UK is serious about competing in the global digital assets market. »
A rapidly expanding global market
The UK framework arrives amid exponential growth in the stablecoin market. According to DeFiLlama data cited by CoinDesk, global capitalization now stands at $303 billion, up from around $200 billion a year earlier. The bulk remains denominated in US dollar-pegged tokens.
Retail usage is also exploding: Visa data show that stablecoin transactions under $250 grew from $500 million in 2019 to nearly $70 billion last year. The House of Lords Financial Services Committee, in a 71-page report titled « Stablecoins: Awaiting Regulation, » observed that the global market « is dominated by US dollar stablecoins and has evolved to serve cryptoasset trading. »
Sarah Breeden, Deputy Governor for Financial Stability at the BoE, described the revised architecture as « truly a world-class regime » and called it « a major milestone in delivering greater choice and innovation in UK payments. »
A global regulatory race
The UK is trying to close the gap on its competitors. The EU’s MiCA regulation fully entered into force in December 2024, while the US adopted the GENIUS Act in July the previous year. The Lords committee report acknowledged that « the UK is behind the United States and the European Union but is now moving in the right direction. »
For Sasha Mills, 2026 will be « foundational in shaping the UK’s financial digital future. » The open question is whether this framework — branded « the most conservative in the world » by critics — can attract international issuers and grow a British tokenized-payments ecosystem worthy of the City of London’s ambitions.
Conclusion
The UK has opted for a regulatory compromise: an operational framework from 2027, a flexible but binding issuance cap, and a reserve architecture aligned with existing prudential standards. Issuers benefit from the removal of holding limits, but must contend with mandatory exposure to the Bank of England and British sovereign debt.
The regime’s success will hinge on its ability to attract issuers against the gravitational pull of the US dollar and the euro, and on the periodic reassessment of the £40 billion cap. If demand surges and guardrails are lifted too slowly, the UK risks becoming a second-tier market; if they are eased in time, London could reclaim its place as a leading hub for tokenized finance.
