The release, which follows an extended consultation period stretching back to late 2023, marks a shift from principles-based discussion to enforceable regulation. For finance directors and treasury teams at UK businesses already using, or evaluating, stablecoin payment rails, the draft rules offer a concrete regulatory perimeter against which operational and counterparty decisions can now be tested.

What the BoE's draft rules actually require

The policy statement and accompanying draft Code of Practice, published on the Bank of England's website on 22 June 2026, set out the supervisory expectations for any entity issuing a stablecoin that meets the threshold for systemic designation.

The framework has its roots in Discussion Paper 2023/4 (DP 2023/4), published by the Bank in November 2023. That paper invited views on how systemic payment stablecoins should be regulated, covering reserve-backing requirements, redemption rights, and governance standards. Feedback from that consultation, according to the Bank, directly shaped the draft rules now published.

Key requirements in the draft Code of Practice, as outlined in the Bank's policy statement, include:

  • Full reserve backing: systemic stablecoin issuers must hold reserves sufficient to honour redemptions at par value at all times. The composition of those reserves is restricted to high-quality liquid assets, mirroring the logic applied to systemically important payment systems.
  • Redemption at par on demand: holders of a systemic stablecoin must be able to redeem their tokens for the underlying fiat currency, in this case sterling, at face value without material delay.
  • Governance and operational resilience: issuers are expected to meet standards comparable to those applied to recognised payment system operators, including business continuity planning, outsourcing controls, and board-level accountability.
  • Supervisory reporting: regular disclosure to the Bank on reserve composition, transaction volumes, and risk exposures.

The Bank will supervise systemic stablecoin issuers under powers granted by the Financial Services and Markets Act 2023 (FSMA 2023), which extended the regulatory perimeter to cover crypto-assets used for payment. Non-systemic stablecoins fall under the Financial Conduct Authority's remit as part of HM Treasury's broader digital-asset regulatory roadmap.

Which stablecoin issuers could be designated systemic

The Bank's framework applies only to stablecoins that reach a scale at which their failure or disruption could pose risks to UK financial stability or the continuity of vital payment services. The precise quantitative thresholds for systemic designation have not been finalised in the draft, though DP 2023/4 indicated that factors such as transaction volume, number of UK holders, and interconnectedness with the wider financial system would all be considered.

At present, the global stablecoin market is dominated by two issuers. Tether, the operator of USDT, and Circle, the issuer of USDC, together account for the vast majority of stablecoin transaction value worldwide. Neither currently operates a sterling-denominated stablecoin at significant scale. However, should either firm, or a new entrant, launch a sterling-pegged product that gains widespread adoption in UK payments, the Bank's framework would apply once the systemic threshold is crossed.

UK-based fintech firms and digital-asset infrastructure providers exploring sterling stablecoin issuance will need to assess whether their projected scale could trigger designation. For smaller operators, the FCA's parallel regime for non-systemic stablecoins will be the relevant framework.

Implications for UK businesses using stablecoin payment rails

The practical significance of the draft rules extends well beyond the issuers themselves. Any UK business that accepts stablecoin payments, holds digital-asset positions in treasury, or relies on fintech payment platforms that settle via stablecoins now has a clearer picture of the regulatory environment.

Counterparty risk assessment

Finance directors evaluating whether to accept stablecoin payments, or to hold stablecoins as part of working capital management, can now assess issuer quality against a defined regulatory standard. A stablecoin designated as systemic and supervised by the Bank carries a different risk profile from an unregulated or offshore-issued token. Treasury policies and counterparty risk frameworks can be updated accordingly.

Banking relationships

UK banks and payment service providers have historically been cautious about servicing businesses with significant stablecoin exposure, partly because of regulatory ambiguity. A clear supervisory regime for systemic issuers may reduce some of that friction. Businesses that have faced difficulties opening or maintaining banking relationships due to digital-asset activity should monitor how clearing banks respond to the new framework.

B2B settlement and cross-border payments

For operators considering stablecoin-based settlement, particularly for cross-border transactions where speed and cost advantages over traditional correspondent banking can be material, the draft rules provide a basis for compliance planning. Knowing that a sterling stablecoin used in settlement is subject to reserve-backing and redemption requirements reduces one layer of uncertainty in payment architecture decisions.

Accounting and audit

The requirement for systemic stablecoins to be redeemable at par has implications for how businesses classify and value stablecoin holdings. A token backed by a regulated reserve and redeemable on demand at face value sits differently on a balance sheet from one without those guarantees. Finance teams should engage auditors early on the treatment of any material stablecoin positions.

Timeline and next steps for operators

The draft Code of Practice published on 22 June 2026 is not yet final, according to the Bank of England's policy statement. A consultation period will follow, during which industry participants can submit feedback on the proposed rules. The Bank has indicated it will consider responses before issuing a finalised Code.

HM Treasury's broader digital-asset regulatory programme, enabled by FSMA 2023, continues in parallel. The FCA is developing its own regime for non-systemic stablecoins and wider crypto-asset activities, meaning the full regulatory picture for digital assets in the UK remains a work in progress.

For CFOs and treasurers at UK businesses, the immediate action points are limited but real. Firms already transacting in stablecoins should review the draft rules to understand which issuers are likely to fall within the systemic perimeter. Those considering stablecoin adoption for payment or treasury purposes now have a regulatory framework to factor into feasibility assessments. And businesses that plan to respond to the Bank's consultation should begin preparing submissions.

The Bank of England's intervention does not resolve every open question. Interoperability between the BoE and FCA regimes, the treatment of non-sterling stablecoins used in UK commerce, and the cross-border recognition of UK-regulated stablecoins all remain areas of active policy development. But the draft Code of Practice represents the most detailed statement yet of how the UK intends to supervise stablecoins that become critical payment infrastructure.
