The UK Government and FCA have made stablecoin regulation a strategic priority for 2026. In a letter to the Prime Minister, the FCA confirmed that supporting UK-issued stablecoins for faster and more convenient payments is a key growth initiative, and the regulatory sandbox has been opened to enable firms to test stablecoin issuance under supervised conditions. This article examines the emerging regulatory framework, the FCA's expectations, and what issuers and payment firms must prepare for.
The UK Approach to Stablecoin Regulation
The UK is taking a phased approach to stablecoin regulation. Phase 1 focuses on fiat-backed stablecoins used for payment purposes — stablecoins that maintain a stable value relative to a fiat currency (principally GBP or USD) and are intended to be used as a means of payment. These payment-focused stablecoins are being brought within the existing regulatory perimeter through amendments to the financial services framework. Phase 2, expected in 2027–2028, will address broader stablecoin use cases including stablecoins used for savings, investment or as part of DeFi protocols.
The regulatory rationale is clear: as stablecoins gain adoption as payment instruments, they must be subject to the same consumer protections and prudential standards as existing electronic money and payment services. A customer using a GBP-backed stablecoin to pay a merchant should have the same rights and protections as a customer using an e-money wallet.
Authorisation Requirements for Stablecoin Issuers
Firms issuing fiat-backed stablecoins for payment purposes will require FCA authorisation. The precise authorisation category is expected to depend on the stablecoin model:
E-money model stablecoins — where the stablecoin represents stored monetary value issued on receipt of funds — are likely to require authorisation as an electronic money institution (EMI) under the EMRs 2011 or their successor regulations. This is the most natural regulatory fit for stablecoins that function as digital cash.
Payment token model — where the stablecoin is used primarily as a payment rail rather than stored value — may fall under payment institution licensing depending on the specific regulatory perimeter definitions in the forthcoming rules.
In both cases, issuers will need to demonstrate compliance with capital requirements, governance standards, AML controls, and the safeguarding regime (including PS25/12 for e-money model stablecoins).
Reserve Backing Requirements
The FCA is expected to require 1:1 reserve backing for fiat-backed stablecoins. This means that for every unit of stablecoin in circulation, the issuer must hold an equivalent value in reserve assets. Reserve assets must be high-quality liquid assets — principally cash deposits at approved credit institutions and short-term government securities. The reserve must be held in segregated accounts under the statutory trust framework introduced by PS25/12.
This approach mirrors traditional e-money safeguarding requirements and ensures that stablecoin holders can redeem their tokens at par value on demand. The FCA has signalled that it will not permit fractional reserve models for payment stablecoins, and that algorithmic stablecoins (which maintain stability through code-based mechanisms rather than asset backing) will not qualify as regulated payment stablecoins under the Phase 1 framework.
Comparison with EU MiCA
The EU's Markets in Crypto-Assets Regulation (MiCA) creates two distinct categories for stablecoins: asset-referenced tokens (ARTs) and e-money tokens (EMTs). ARTs reference a basket of assets and require specific authorisation; EMTs reference a single fiat currency and must be issued by credit institutions or EMIs. The UK framework is simpler in structure but draws on similar principles — the key difference is that the UK is integrating stablecoins into its existing payments regulatory framework rather than creating a standalone regime.
Firms operating across both the UK and EU will need to understand both frameworks and ensure compliance in each jurisdiction. Dual-jurisdiction stablecoin issuance will require careful regulatory planning.
Implications for Payment Firms
Payment firms that do not issue stablecoins but accept or facilitate stablecoin payments will also face regulatory obligations. These are expected to include: clear customer disclosures about the nature of stablecoin payments; information about redemption rights and the backing of the stablecoin; operational resilience requirements for stablecoin payment processing; and AML controls appropriate to the risk profile of stablecoin transactions.
Payment institutions considering integrating stablecoin payments into their service offerings should begin assessing the regulatory implications now. This includes evaluating whether their existing PI authorisation covers stablecoin payment activities, or whether additional regulatory permissions will be required.
What Firms Should Do Now
- Monitor FCA consultations on stablecoin regulation closely — draft rules are expected in 2026.
- If you are considering stablecoin issuance, evaluate whether the FCA's regulatory sandbox is appropriate for your business model.
- Assess your existing authorisation permissions against the expected stablecoin regulatory perimeter.
- Begin planning reserve management infrastructure, including segregated account arrangements with approved credit institutions.
- Review your AML framework for adequacy in relation to stablecoin transaction risks.
