Bank of England Stablecoin Rules Relaxed for 2027 Launch
The Bank of England (BoE) has taken a significant step toward establishing a comprehensive regulatory framework for stablecoins with the publication of its draft rules on Monday, June 22, 2026. The policy statement outlines how regulated British pound-backed stablecoins would operate within the UK financial system, with the central bank aiming to finalize its rulebook by the end of 2026 ahead of a planned full implementation in 2027.
Key Provisions of the New Framework
The most notable adjustments in the new policy represent a response to industry feedback following the BoE’s November 2025 consultation. The revised framework introduces several key changes:
- Increased Reserve Flexibility: Systemic stablecoin issuers will now be permitted to hold up to 70% of their reserves in interest-bearing government debt, an increase from the previously proposed 60% cap. This adjustment provides issuers with greater flexibility in generating yield on their reserve assets while maintaining a strong backing.
- Abolition of Holding Limits: The BoE has completely scrapped its proposed per-user holding limits, which would have restricted individuals to £20,000 and businesses to £10 million worth of stablecoins per token. These limits were initially intended to prevent large-scale migration of deposits from the traditional banking system, which could have impacted credit availability.
- Temporary Issuance Cap: In place of holding limits, the central bank has introduced a temporary aggregate issuance cap of £40 billion (approximately $52.8 billion) per stablecoin. The BoE has described this as a “guardrail” that will be reviewed regularly and removed once risks to credit provision are adequately addressed .
Regulatory Timeline and Scope
The BoE’s publication moves the UK closer to launching a dedicated regulatory framework for stablecoins. The central bank is targeting the finalization of its rulebook by the end of 2026, with the new regime expected to be fully operational by 2027 .
The rules apply specifically to systemic stablecoins—defined as those widely used in payments that could pose risks to the UK’s financial stability. HM Treasury is responsible for determining whether a stablecoin falls within this systemic regime. Stablecoins deemed non-systemic, primarily those used for crypto-asset trading, will remain under the supervision of the Financial Conduct Authority (FCA).
Industry Response and Remaining Questions
The financial industry has largely welcomed the BoE’s more flexible approach, though some concerns remain.
Mark Fairless, CEO of ClearBank, noted: “The Bank of England has clearly listened on holding limits, moving away from a complex and restrictive approach towards a more proportionate framework. That is a positive step.” However, he cautioned that “further progress is needed to ensure the regime does not constrain sustainable business models, particularly through the backing asset requirements”.
Katie Harries, Coinbase’s head of policy for Europe, highlighted that the UK is now the only country capping the issuance of stablecoins in its own currency. She raised two critical questions: the definition of “temporary” for the per-coin issuance cap and whether stablecoins will be permitted for settlement in core wholesale markets. “Without which the UK’s tokenization ambitions will not be delivered,” she stated.
Evolution from Previous Proposals
The shift in the BoE’s approach represents a direct response to feedback from digital asset companies during the consultation period. In May 2026, BoE Deputy Governor Sarah Breeden indicated that the central bank was reconsidering its proposed holding limits and reserve requirements following industry warnings that the restrictions could hinder adoption and make UK-issued stablecoins less competitive with US dollar-backed rivals.
The original November 2025 consultation argued that holding limits were necessary to prevent large-scale shifts of deposits out of the banking system, which could reduce the availability of credit to households and businesses. However, respondents warned that such restrictions would limit the usability of stablecoins and create operational challenges for issuers.
Implications for the UK Crypto Ecosystem
The revised framework signals the UK’s intent to foster innovation while maintaining financial stability. By easing reserve requirements and eliminating holding limits, the BoE has created a more attractive environment for stablecoin issuers looking to operate within a regulated perimeter.
However, the introduction of a £40 billion issuance cap—unique among global regulators—introduces an element of uncertainty. The temporary nature of this cap suggests it may be a transitional measure designed to allow the BoE to monitor the development of the stablecoin market and its impact on the broader financial system before removing restrictions entirely.
Looking Ahead to 2027
With the draft rules now published, the focus shifts to the consultation period and the eventual finalization of the rulebook by the end of 2026. The 2027 launch target positions the UK alongside other major jurisdictions developing stablecoin regulations, though the specific approach—with its issuance cap—remains distinct.
The successful implementation of this framework could cement the UK’s position as a hub for digital asset innovation while ensuring that stablecoin systems are robust, transparent, and integrated safely into the traditional financial system. As the regulatory landscape continues to evolve, market participants will be watching closely to see how the final rules shape the future of pound-denominated stablecoins.
