The Bank of England has published a policy statement and accompanying draft rules for sterling-denominated stablecoins that could meet a systemic threshold, in a move analysts at Hogan Lovells Cadwalader called a "key milestone" for the United Kingdom's digital asset framework.

The publication advances the UK's regulatory perimeter for fiat-backed digital payment tokens, shifting the policy discussion from consultation exercises to draft binding text. It covers GBP-denominated stablecoins — blockchain-based tokens engineered to maintain a stable value against the pound — that authorities may classify as systemically important to UK financial stability.

Under the proposed approach, the Bank of England would act as the primary prudential supervisor for systemic stablecoin issuers, with the Financial Conduct Authority retaining conduct-of-business oversight for cryptoasset firms.

What does the draft framework cover?

The Bank's rules set out the proposed supervisory approach for systemic stablecoin arrangements, addressing the criteria for determining systemic significance and the prudential standards that would apply to issuance, reserve management and redemption obligations.

The framework complements HM Treasury's broader cryptoasset regulatory agenda, which has previously signalled intent to bring fiat-backed payment tokens within a regulated perimeter and to distinguish between systemic and non-systemic regimes.

How would supervision be divided?

The draft places prudential supervision for systemic stablecoin issuers within the Bank of England's remit, covering capital, liquidity and resolution planning. The FCA would retain responsibility for conduct standards applicable to cryptoasset firms, including those issuing non-systemic tokens.

The supervisory split mirrors the UK's broader regulatory architecture, in which the central bank oversees prudential matters for systemically important institutions while the FCA supervises market conduct across financial services.

Why does this matter for market participants?

UK authorities have identified stablecoin oversight as a regulatory priority, engaging with industry on the treatment of fiat-pegged tokens used in retail payments, wholesale settlement and cross-border remittances. The publication of draft text represents the Bank's first concrete regulatory output under the emerging regime, giving market participants a substantive basis for technical feedback.

For issuers, custodians and payment firms, the draft rules introduce compliance considerations around capital adequacy, liquidity buffers and reserve composition that extend beyond existing AML and sanctions obligations. The framework also establishes a clearer delineation between systemic and non-systemic stablecoin regimes, with lighter-touch oversight expected for smaller issuers below the systemic threshold.

What happens next?

The Bank of England is expected to open a formal consultation on the draft rules, with industry participants invited to submit technical feedback before finalisation. Implementation will require coordination with the FCA's parallel work on conduct rules for cryptoasset firms and alignment with primary legislation progressing through Parliament.
