FCA Stablecoin Authorisation 2026: Requirements for UK Stablecoin Issuers

The UK now has a defined regulatory framework for issuing qualifying stablecoins. Firms intending to issue a qualifying stablecoin in the UK will require FCA authorisation under the new cryptoasset regime and will need to meet detailed requirements covering backing assets, redemption, safeguarding, prudential resources, governance and disclosures.

The FCA published its final rules for non-systemic UK-issued qualifying stablecoins in June 2026. The authorisation gateway opens on 30 September 2026, while the new regulatory regime is expected to come into force on 25 October 2027. Firms planning to issue a UK stablecoin should therefore be designing the product, legal structure, reserve arrangements and regulatory framework now rather than waiting until 2027.

Stablecoin authorisation is not simply a crypto registration exercise. The FCA expects qualifying stablecoins to operate as credible money-like instruments, which means the issuer must demonstrate that tokens are properly backed, holders can redeem them reliably and the assets supporting the stablecoin remain protected if the issuer fails. The wider cryptoasset authorisation timetable and process is set out in our FCA cryptoasset authorisation 2026/27 guide.

UK stablecoin regulation at a glance

The £350,000 permanent minimum requirement is a baseline rather than necessarily the issuer's final own funds requirement. The wider prudential regime can require more capital depending on fixed overheads, applicable K-factors and the overall risk profile of the business.

What is a UK qualifying stablecoin?

The new regime applies to qualifying stablecoins issued in the UK. Broadly, these are cryptoassets designed to maintain a stable value by reference to fiat currency through backing assets intended to support that value.

The FCA's framework is designed around the principle that a regulated UK stablecoin should operate as a credible money-like instrument rather than a speculative investment. This is why the rules focus heavily on full backing, redemption rights, protection of the backing pool and clear information for holders.

The precise classification of a token should be determined from its legal and economic characteristics rather than the name attached to the product. Calling a token a stablecoin does not itself determine whether it falls within the qualifying stablecoin regime. Firms should therefore establish the regulatory classification before finalising the token structure. The reference asset, redemption rights, backing mechanism, place of issuance and role of the issuer can all affect the regulatory analysis.

Who needs FCA authorisation to issue a stablecoin?

A firm carrying on the regulated activity of issuing a qualifying stablecoin in the UK will require FCA authorisation once the new regime takes effect.

This is a specific regulated activity. An existing FCA cryptoasset registration under the Money Laundering Regulations is not sufficient, and an EMI or Payment Institution permission does not automatically authorise the issuance of a qualifying stablecoin.

Where an existing FSMA-authorised business wants to issue qualifying stablecoins, it will generally need the relevant permission added to its existing authorisation. The FCA will assess whether the firm's governance, prudential resources, operating model and systems are appropriate for the new activity.

The legal entity chosen to issue the stablecoin therefore matters. Groups containing banks, EMIs, payment firms or existing cryptoasset businesses should assess whether issuance should sit within an existing regulated entity or a separate company before the application and operating structure are developed. Our licensing and authorisation team advises on the appropriate entity structure and permission set.

FCA regulation and systemic stablecoins

The FCA regime principally governs non-systemic UK-issued qualifying stablecoins. Where a stablecoin becomes sufficiently important to the UK payments system, HM Treasury can recognise the relevant arrangement as systemic, bringing the Bank of England into the regulatory framework.

A UK stablecoin issuer could begin as a non-systemic firm regulated by the FCA and later move into joint FCA and Bank of England regulation if the stablecoin grows to systemic significance. In some circumstances, an issuer could also be recognised as systemic from launch where the expected scale and role of the arrangement justify that treatment.

This distinction matters for businesses with ambitions to create a widely used sterling payment stablecoin or major settlement asset. The regulatory architecture, reserve model and operational arrangements may need to support a future transition from FCA-only supervision to a joint regulatory framework. Most new issuers will begin under the FCA regime, but firms with credible plans for substantial payments-system adoption should consider the systemic framework within their longer-term regulatory design.

Stablecoins must be fully backed

A core principle of the FCA framework is that UK-issued qualifying stablecoins must be fully backed. The issuer must maintain appropriate backing assets for the stablecoins it has issued in accordance with the FCA's requirements. The objective is to preserve confidence that the stablecoin can maintain its intended value and that holders can redeem their tokens reliably.

The reserve cannot simply be treated as working capital available to fund the issuer's wider business. The backing pool exists for the benefit of stablecoin holders and is subject to detailed rules governing eligible assets, segregation, custody, reconciliation and liquidity.

The backing model should therefore be designed before the application is prepared. Applicants will need to demonstrate how backing assets are acquired, where they are held, how the issued stablecoin population is calculated and how the firm will maintain compliance as issuance and redemption volumes change.

Backing assets must be protected through a statutory trust

The FCA's final framework requires the backing asset pool to be held on statutory trust for the benefit of qualifying stablecoin holders. The purpose is to separate the backing assets from the issuer's own assets and provide clearer protection if the issuer enters financial difficulty or insolvency. The issuer acts as trustee and is subject to the obligations associated with holding the backing assets for tokenholders.

This is a substantive structural requirement. Firms need appropriate legal documentation, banking or custody arrangements, internal controls and accounting treatment capable of maintaining separation between the issuer's corporate assets and the stablecoin backing pool.

The arrangement also affects insolvency planning and wind-down. The firm should be able to demonstrate how backing assets and holder records would be identified, reconciled and dealt with if the issuer failed.

What assets can be used to back a UK stablecoin?

The FCA's framework limits the backing pool to assets that support stability, liquidity and reliable redemption. The detailed composition rules distinguish between permitted categories and include requirements intended to control liquidity and market risk.

For applicants, the commercial challenge is balancing safety and liquidity with the economics of operating the stablecoin. A reserve portfolio designed primarily to maximise yield may conflict with the FCA's objectives, while an excessively complex reserve structure can make liquidity management, reconciliation and redemption harder to control.

The backing strategy should therefore be linked directly to expected issuance, redemption behaviour and stress conditions. Firms need to understand how quickly assets can be converted into the reference currency and how the reserve will perform during periods of unusually high redemption demand. Third-party concentration also matters. A stablecoin whose reserve depends heavily on one bank, custodian or provider may create operational and concentration risk even where the individual backing assets satisfy the regulatory criteria.

Redemption rights are central to the FCA regime

Holders of UK-issued qualifying stablecoins must have an effective route to redeem their tokens in accordance with the FCA's rules. Redemption is one of the principal mechanisms supporting confidence that the token remains linked to its reference currency.

The final rules require valid redemption requests to be completed as soon as practicable and generally no later than the end of the business day following the relevant receipt of the qualifying stablecoin, subject to the detailed provisions and exceptions in the FCA rules.

Issuers cannot impose unreasonable obstacles that make redemption practically inaccessible. The operational model therefore needs reliable processes for receiving requests, completing required customer checks, calculating redemption amounts, receiving and burning tokens where necessary and releasing fiat promptly. Redemption should also be stress-tested. A process that works for normal daily volumes may fail during a market event when a large number of holders seek redemption simultaneously.

What happens if redemption must be suspended?

The FCA permits redemption to be suspended only in defined exceptional circumstances and where the relevant regulatory conditions are satisfied. The issuer should first consider whether the underlying problem can be addressed without suspending redemption. Where suspension becomes necessary, the FCA must be notified and the issuer must comply with the applicable requirements governing suspension and restart.

This places significant importance on contingency planning. Firms should identify circumstances capable of threatening redemption, including liquidity problems, failure of a critical bank or custodian, cyber incidents, legal restrictions or material problems with the backing pool. The issuer should also have credible contingency arrangements where a critical third-party provider fails. Redemption risk should be treated as a core enterprise risk rather than merely an operational treasury process.

Minimum capital requirement for UK stablecoin issuers

The FCA has set a £350,000 permanent minimum requirement for firms authorised to issue qualifying stablecoins. This is the regulatory capital floor for the activity, but it does not mean that every issuer will require only £350,000 of capital. Under the wider CRYPTOPRU framework, the firm's own funds requirement is determined by the highest applicable requirement, which can include the permanent minimum requirement, fixed overheads requirement and relevant K-factor requirements.

The amount required can therefore increase as the business grows or its risk profile becomes more complex. Firms must also consider liquidity requirements separately from regulatory capital and maintain sufficient resources for an orderly wind-down.

Financial forecasts should model the regulatory position throughout the forecast period rather than simply showing that the business meets the £350,000 threshold on the application date. Rapid growth can materially increase operating expenditure, regulatory exposure and required financial resources.

Stablecoin issuers face additional liquidity requirements

Stablecoin issuers must maintain sufficient liquidity to support redemption and meet the wider prudential requirements of the regime. A stablecoin may be fully backed in accounting terms but still face serious difficulties if its backing assets cannot be converted into money quickly enough to meet redemption requests. Liquidity management therefore needs to assess both normal operations and stressed redemption scenarios.

The issuer should understand the liquidity profile of each asset in the backing pool, settlement times, market access and dependence on counterparties or custodians. The FCA application should demonstrate that the reserve and liquidity model supports the promise made to holders: that the stablecoin can be redeemed reliably at the expected value.

Can a UK stablecoin pay interest?

The FCA's final rules prohibit the issuer from passing interest or income generated by the backing asset pool to stablecoin holders. The policy reflects the FCA's intention that qualifying stablecoins operate primarily as money-like instruments rather than investment products. Paying holders a return derived from reserve assets could change the economic character of the token and create additional regulatory concerns.

This does not necessarily prohibit every customer incentive funded from other sources, but product design requires care. A stablecoin marketed around yield, passive returns or reserve-generated income may not fit comfortably within the intended framework and could raise separate regulatory questions. The commercial economics of the stablecoin should therefore be tested against the regulatory model before launch.

Governance and Senior Managers requirements

A stablecoin issuer will be a fully authorised FCA firm and must maintain governance proportionate to the nature and scale of its activities. The Senior Managers and Certification Regime will apply to authorised cryptoasset firms. Responsibilities for the stablecoin product, prudential resources, backing assets, redemption, financial crime, technology and other material risks need clear ownership at senior level.

The FCA will assess whether management has the experience and capacity required to operate the business safely. Stablecoin issuance combines elements of treasury management, technology, custody, payments and financial-services compliance, making governance more demanding than the simplicity of the customer-facing product might suggest.

Board reporting should provide meaningful information about backing ratios, redemption activity, liquidity, operational incidents, reserve concentration, compliance breaches and other material risks.

Disclosure and transparency requirements

The FCA framework requires stablecoin issuers to provide clear information about the product and maintain appropriate disclosures for prospective and existing holders. The issuer remains responsible for the accuracy and updating of required stablecoin information. This responsibility cannot simply be transferred to a trading platform or intermediary that distributes the token.

Disclosures should explain the stablecoin's operation, backing, redemption arrangements and material risks in a way that enables holders to understand what they are acquiring. Firms must also maintain appropriate governance over public information concerning backing and redemption. The FCA requires strong records, reconciliations and independent assurance around relevant backing statements, reinforcing the link between operational controls and public confidence in the stablecoin.

Stablecoin issuance and custody are separate regulatory questions

Issuing a stablecoin does not automatically mean that every related activity is covered by the issuance permission. A firm that also safeguards cryptoassets for customers may require separate cryptoasset custody permission. This can arise where the issuer provides hosted wallets, controls private keys or otherwise holds qualifying cryptoassets on behalf of customers.

Some businesses may combine issuance and custody within one authorised entity, while others may use separate regulated entities or third-party custodians. The appropriate structure depends on governance, operational risk, prudential consequences and the wider customer proposition. Third-party custody does not remove the issuer's responsibility for the stability and operation of its own product. Appropriate due diligence, oversight, contractual protection and contingency arrangements remain necessary. The general perimeter for cryptoasset service providers is set out on our UK CASP licence page.

Stablecoins used for payments may also engage payments regulation

Stablecoin issuance sits within the new cryptoasset regime, but using stablecoins to provide payment services creates a second regulatory dimension. HM Treasury is developing a future payments framework intended to accommodate certain stablecoins and other tokenised forms of money. Depending on the business model, a firm could therefore need to consider cryptoasset authorisation alongside Payment Institution or Electronic Money Institution requirements.

For example, an issuer may create the stablecoin while another group entity provides fiat payment accounts, money remittance or merchant payment services. The regulatory analysis depends on who receives customer money, who executes each payment, how conversion occurs and which entity contracts with the customer. The permissions should therefore be mapped across the entire customer journey rather than treating stablecoin issuance as an isolated activity.

What about overseas stablecoins?

The UK issuance regime is focused on qualifying stablecoins issued in the UK. A stablecoin issued overseas does not become a UK-issued qualifying stablecoin merely because it is available to UK customers.

Overseas-issued stablecoins can still fall within the wider UK cryptoasset framework when firms provide custody, dealing, arranging or other regulated services involving those assets. The analysis therefore needs to distinguish between regulation of the issuer and regulation of UK firms providing services around the token.

The Government is also developing the future treatment of overseas stablecoins used for payments. International groups should therefore decide carefully where the issuing entity sits and what activities the UK entity will perform. A global structure that works under EU MiCA or another overseas regime will not automatically satisfy the UK regulatory perimeter.

What should a stablecoin authorisation application contain?

A stablecoin application needs to explain both the regulated business and the operation of the stablecoin itself. The regulatory business plan should describe the ownership structure, issuing entity, target customers, distribution model, reference currency, minting and burning processes, expected transaction volumes, revenue model and role of material third parties. The FCA should be able to follow the complete lifecycle of the stablecoin from issuance through circulation and redemption.

The backing-asset framework requires particular detail. The application should explain how the backing requirement is calculated, which assets will be held, how they will be protected under the statutory trust, where they will be custodied, how reconciliations operate and how liquidity will be managed. The application should also cover prudential resources, financial forecasts, redemption arrangements, governance, Senior Managers responsibilities, risk management, financial crime, Consumer Duty, operational resilience, outsourcing, wind-down planning and disclosure controls.

Where the issuer also intends to provide custody or other regulated cryptoasset services, the application must address the additional permissions and requirements associated with those activities.

What should prospective stablecoin issuers do now?

The first step is to confirm whether the proposed token and issuance structure fall within the UK qualifying stablecoin regime. This should be completed before finalising the issuing entity, token terms, reserve arrangements and customer contracts. The issuer should then design the backing and redemption framework. Banking and custody partners need to be capable of supporting the statutory trust, reserve composition, liquidity and operational requirements expected by the FCA.

Governance and financial resources should be developed alongside the product. Waiting until the technology has been built to consider capital, Senior Managers, operational resilience and regulatory controls can result in expensive restructuring. Firms should also decide whether the stablecoin will operate solely as a cryptoasset product or form part of a wider payment ecosystem. Where payment services, electronic money, custody or other regulated activities are involved, those permissions and legal entities should be mapped before the FCA application is prepared.

How Regulatory Counsel can help

Regulatory Counsel supports stablecoin issuers through the complete UK regulatory process, from initial product and perimeter analysis through to FCA authorisation and post-authorisation implementation.

We assess the proposed token, issuance model and wider business structure to determine which FCA permissions are required. We then help design the regulatory framework around backing assets, statutory trust arrangements, redemption, prudential resources, governance, custody, financial crime, operational resilience and customer treatment.

Our work can include the regulatory business plan, FCA application, financial forecasts and capital calculations, governance framework, risk management, backing and redemption policies, disclosures, Consumer Duty, outsourcing and the wider policies and procedures required for authorisation.

Where the business also involves cryptoasset custody, trading or intermediary services, we can incorporate the relevant additional permissions into the regulatory strategy. Where the model involves regulated payment services or electronic money, the payments and cryptoasset permissions should be structured together so responsibilities between entities are clear.
