Bank of England drops stablecoin holding limits in revised framework
Final stablecoin rules expected by the end of 2026 will form part of a broader UK crypto regulatory structure covering custody and tokenisation.
The Bank of England has revised its proposed regulatory approach for sterling-denominated systemic stablecoins, removing planned individual holding limits and introducing a temporary £40 billion issuance guardrail for each systemic stablecoin.
The policy statement and draft Code of Practice set out how the Bank intends to regulate stablecoin issuers that become systemic because their use in payments could pose risks to UK financial stability. The final Code of Practice is expected by the end of 2026.
The Bank said it had changed its approach following industry feedback on two key issues: backing asset composition and holding limits. Earlier proposals would have imposed individual limits of £20,000 per coin for individuals and £10 million for businesses, with possible exemptions.
Instead, the Bank now plans to use a temporary issuance guardrail, initially set at £40 billion per systemic stablecoin. The Bank said the approach would be simpler to implement while still managing credit risks as stablecoins scale.
Backing asset rules have also been adjusted. The Bank now proposes a steady-state backing asset composition of 70% short-term UK government debt and 30% unremunerated Bank of England deposits, compared with an earlier 60/40 proposal. It said the change should support more viable stablecoin business models while maintaining safeguards for financial stability.
The framework forms part of the UK’s wider stablecoin regime, under which the FCA will regulate qualifying stablecoin issuance, custody and trading, while systemic stablecoins recognised by HM Treasury will be regulated jointly by the Bank and the FCA.
The Bank said the approach is intended to support innovation and market entry while preserving trust in money, safeguarding financial stability and enabling sterling-denominated stablecoins to operate at scale.
Why does it matter?
The Bank of England’s revised approach shows the UK trying to make systemic stablecoin regulation more workable without abandoning financial stability safeguards. Removing individual holding limits addresses a major industry concern, while the £40 billion issuance guardrail keeps regulatory focus on systemic scale rather than day-to-day user holdings. The framework also matters because stablecoins are being treated as part of the UK’s future payments landscape, alongside bank deposits, tokenised deposits and potentially a retail CBDC.
