Stablecoin Payments Regulation UK 2026: Do You Need an EMI, PI or Cryptoasset Permission?

Stablecoin Payments Regulation UK 2026: Do You Need an EMI, PI or Cryptoasset Permission?

Stablecoins are moving rapidly into mainstream payments, but there is no single UK “stablecoin licence” that covers every business model. A fintech using stablecoins may require Payment Institution authorisation, Electronic Money Institution authorisation, permission under the new FCA cryptoasset regime, or a combination of permissions depending on what the business actually does.

The regulatory position turns on the substance of the service rather than the technology being used. A business that uses stablecoins only as an internal settlement rail can have a very different regulatory profile from one that allows customers to buy, hold, transfer and redeem stablecoins through its platform. The flow of funds, ownership of assets, contractual responsibilities and role of each entity therefore need to be mapped before the correct regulatory route can be determined.

The position is also evolving. The FCA published final rules for non-systemic UK-issued qualifying stablecoins in June 2026, while HM Treasury is separately consulting on how certain stablecoins and other tokenised forms of money should be integrated into the UK payments framework. For founders, existing PIs and EMIs, the practical question is therefore not simply whether stablecoins are regulated, but which permissions are required for the specific product being built.

Is there a stablecoin licence in the UK?

There is no single FCA permission called a stablecoin licence. Different regulated activities can arise depending on whether a firm issues a stablecoin, holds cryptoassets for customers, arranges or executes transactions, exchanges cryptoassets, or provides an underlying payment service.

A business issuing a non-systemic qualifying stablecoin in the UK will fall within the new FCA regime for stablecoin issuance once the new cryptoasset framework comes into force. A firm safeguarding qualifying cryptoassets for customers may require cryptoasset custody permission, while businesses conducting dealing, arranging or other regulated cryptoasset activities may require separate permissions under the wider regime.

Payments regulation can apply alongside this. If a business receives customer money and provides money remittance, operates payment accounts or executes regulated payment transactions, the fact that stablecoins form part of the infrastructure does not automatically remove those activities from the Payment Services Regulations.

The result is that two businesses describing themselves as “stablecoin payment platforms” can require completely different authorisation strategies.

Stablecoin permissions at a glance

Business model or activity	Principal regulatory issue
Issuing a qualifying UK stablecoin	FCA stablecoin issuance permission under the new cryptoasset regime
Holding stablecoins or qualifying cryptoassets for customers	Cryptoasset custody requirements may apply
Buying, selling or arranging cryptoasset transactions	Relevant cryptoasset intermediary permissions may apply
Receiving fiat and executing customer payments	Payment Institution permissions may apply
Issuing electronic money balances	EMI authorisation may apply
Using stablecoins within a cross-border payment flow	Payments and cryptoasset regimes may both need to be analysed
Existing PI or EMI introducing tokenised payments	A Variation of Permission may be required under the future framework
Using stablecoins purely as an internal settlement mechanism	Treatment depends on customer exposure and the firm’s exact role

The correct permission cannot be identified simply by asking whether the platform “uses blockchain” or “uses USDC”. The complete transaction needs to be analysed from the point at which the customer provides money through to the point at which the beneficiary receives value.

When can a stablecoin business need a Payment Institution licence?

A stablecoin business may require Payment Institution authorisation where the underlying service amounts to a regulated payment service.

Consider a company that accepts GBP from a UK customer, uses stablecoin infrastructure to transfer value across borders and then pays the beneficiary in local currency. The customer may never acquire or interact with the stablecoin and may view the service simply as an international money transfer.

In that model, the use of blockchain does not necessarily change the underlying regulated activity. If the firm receives funds from a payer for the purpose of transmitting a corresponding amount to a beneficiary, money remittance or another regulated payment service may still be taking place.

The regulatory analysis would normally consider who receives the customer’s money, who contracts to provide the payment service, who is responsible for paying the beneficiary and whether the customer ever owns or controls the stablecoin. It will also consider whether another regulated institution performs part of the transaction and whether the fintech itself is providing a regulated service or merely technology to another authorised firm.

Where the underlying activity remains a regulated payment service, an Authorised Payment Institution permission may be required even where stablecoins are used as part of the settlement infrastructure.

When might an EMI licence be required?

An Electronic Money Institution licence is relevant where the business issues electronic money rather than simply executing payment transactions. Electronic money is monetary value stored electronically, issued on receipt of funds and representing a claim on the issuer that can be used to make payments.

This can create confusion because electronic money and stablecoins may appear commercially similar. Both can represent digitally stored value and both can potentially be used to transfer value between users, but they are not automatically the same regulatory product.

Traditional fiat-backed customer balances issued as electronic money remain governed by the electronic money framework. Qualifying stablecoins issued under the new UK regime will instead fall within the specific regulatory framework for cryptoassets and stablecoin issuance.

A business can nevertheless involve both. A fintech might issue GBP or EUR e-money balances to customers while using stablecoins for settlement or allowing customers to access separate tokenised services. In that case, the regulatory structure may need to consider the Electronic Money Institution framework alongside any relevant cryptoasset permissions.

The distinction should be established before the product is built. Trying to determine whether a product is e-money, a stablecoin or a payment service only after the technology, contracts and customer flows have been fixed can result in significant restructuring.

What if the business uses USDC, USDT or another third-party stablecoin?

Many fintech businesses do not intend to issue their own stablecoin. Instead, they want to use an existing stablecoin such as USDC or USDT for settlement, cross-border transfers or treasury purposes.

Using a third-party stablecoin does not itself determine whether the fintech needs FCA authorisation. The important issue is how that stablecoin enters the customer transaction and what role the business performs.

At one end of the spectrum, an authorised payment firm could receive GBP from a customer and use a stablecoin entirely within its own settlement infrastructure before paying the beneficiary in fiat. The customer may never own, control or even interact with the stablecoin.

At the other end, a platform could allow customers to exchange GBP into stablecoins, hold those assets in a hosted wallet, transfer them to other users and later redeem them into fiat. That model raises a broader set of regulatory questions involving payments, cryptoasset transactions, custody, safeguarding and financial crime.

The difference is important because outsourcing the stablecoin infrastructure does not automatically make the fintech unregulated. A business can still cross the regulatory perimeter if it receives customer funds, provides the regulated service contractually, controls customer assets or performs regulated transactions itself.

UK-issued and overseas stablecoins may be treated differently

The developing UK framework draws an important distinction between qualifying stablecoins issued under the UK regime and stablecoins issued overseas. HM Treasury’s July 2026 proposals envisage certain regulated stablecoins being capable of functioning as money within the future payments framework rather than being treated solely as cryptoassets.

The Government is also considering how overseas stablecoins should be treated, including whether stablecoins issued under appropriately recognised overseas regimes could receive comparable treatment. This means the regulatory outcome may depend not only on how the stablecoin is used, but also on where and under what regulatory regime it is issued.

That distinction could become commercially important for fintech firms selecting stablecoins and infrastructure partners. A payment model built around a UK-regulated qualifying stablecoin may ultimately sit differently within the payments framework from a similar service built around an overseas token that does not receive equivalent regulatory treatment.

Businesses designing products now should therefore avoid selecting a stablecoin solely on the basis of liquidity, technology or market adoption. Regulatory treatment, issuer status and the role of the asset within the customer journey should also form part of product and partner due diligence.

The HM Treasury consultation on modernising payment services regulation sets out the Government’s proposed direction for integrating stablecoins and other tokenised payment methods into the future payments framework.

Do existing PIs and EMIs automatically have permission to use stablecoins?

An existing PI or EMI should not assume that its current FCA permissions automatically cover every stablecoin or tokenised payment service it may wish to introduce.

HM Treasury is considering whether authorised and registered payment firms should require a Variation of Permission before conducting payment services using tokenised forms of money. The reason is that a stablecoin-based service can introduce risks that are materially different from those involved in a conventional fiat payment model, including technology, custody, liquidity, redemption, financial crime and third-party dependency risks.

For an existing regulated firm, the analysis should begin by comparing the new product with the activities already covered by its permissions. The firm should then assess whether customers will own or hold cryptoassets, whether the business will provide custody or exchange functionality, how the flow of funds changes and whether new regulated activities are being introduced.

Changes to safeguarding, financial crime controls, governance, operational resilience and third-party oversight may also be required even where the underlying payment service appears similar. The FCA will be interested in the risks created by the actual operating model, not simply whether the customer proposition has retained the same commercial label.

Where a firm is adding or materially changing regulated activities, an FCA Variation of Permission may ultimately be required before the new service can be launched.

Will a stablecoin issuer also need a PI or EMI permission?

Potentially, but not automatically. The future UK framework is being designed to avoid unnecessary duplication between stablecoin regulation and payment services regulation. HM Treasury is considering how firms authorised for qualifying stablecoin activities should interact with the payments regime where the stablecoin is used directly to make payments.

This does not mean that a stablecoin issuance permission will necessarily cover every activity performed by the business. A firm that also operates payment accounts, provides money remittance, acquires merchants, issues cards or executes conventional fiat payments may still need additional payment permissions depending on how the final framework is implemented.

The same applies where the business provides cryptoasset activities beyond issuance. Custody, dealing, arranging transactions or other regulated cryptoasset services may need to be separately analysed.

The correct authorisation strategy therefore depends on the whole business rather than the firm’s primary product. A company may market itself as a stablecoin issuer while actually performing several distinct regulated activities across the customer journey.

What about stablecoin wallets and custody?

The word “wallet” is frequently used as though it describes one regulatory activity, but wallet models can operate very differently.

A non-custodial interface where the customer alone controls the private keys may have a different regulatory profile from a hosted wallet where the provider holds or controls cryptoassets on the customer’s behalf. Under the new UK cryptoasset regime, safeguarding qualifying cryptoassets for customers becomes a regulated activity and firms performing that function will need to consider the FCA’s custody requirements.

The position becomes more complex where stablecoins are held temporarily as part of a regulated payment transaction. HM Treasury is seeking to reduce unnecessary overlap between cryptoasset custody and payments regulation where an asset is being safeguarded specifically in the course of providing a payment service.

That policy direction should ultimately make the framework more coherent, but firms should not assume that payment and custody permissions are interchangeable. The precise role of the wallet provider, who controls the assets and why those assets are being held remain central to the regulatory analysis.

What is the most efficient regulatory route for a new stablecoin payments fintech?

For many early-stage businesses, the most efficient regulatory model is not necessarily to obtain every possible permission directly.

A startup may be able to use regulated infrastructure partners for fiat accounts, payment execution, stablecoin conversion, custody or card issuing while retaining responsibility for the customer experience and technology layer. This can reduce the initial regulatory burden and allow the business to test the commercial proposition before building a larger regulated infrastructure stack.

However, the partnership model needs to be designed carefully. Using an authorised PI, EMI or cryptoasset provider underneath the product does not automatically mean the fintech itself is outside the regulatory perimeter.

The critical questions remain who contracts with the customer, who receives or controls customer money, who performs each regulated activity and what representations are made about the service. A fintech can unintentionally become the regulated service provider even where licensed infrastructure sits behind it if the legal and operational structure is not aligned correctly.

For this reason, the regulatory structure should ideally be determined before infrastructure providers are selected and contracts are signed. Changing a payment flow or reallocating regulatory responsibility is substantially harder once banking integrations, customer agreements and technology architecture have already been built.

Payments and cryptoasset permissions can overlap

The most important strategic development is that stablecoins are becoming a payments issue as well as a cryptoasset issue.

The UK Government increasingly recognises that regulated stablecoins can function as payment and settlement instruments rather than simply assets that people buy and sell. At the same time, issuing, safeguarding or intermediating cryptoassets remains capable of triggering separate regulated activities.

A stablecoin business may therefore sit predominantly within the payments framework, predominantly within the cryptoasset regime or across both. The correct answer depends on the underlying activity rather than whether the company describes itself as a payments company or a crypto company.

For founders, the correct sequence is to map the customer journey and flow of funds first, identify which entity performs each activity and then determine which activities are regulated. Only after that should the business decide which permissions it will obtain directly and which regulated functions, if any, will be performed by third-party providers.

The FCA cryptoasset authorisation timetable

The new UK cryptoasset regulatory regime is expected to come into force on 25 October 2027. The FCA application period is scheduled to open on 30 September 2026 and close on 28 February 2027.

This timetable is particularly important for businesses that expect to carry on regulated cryptoasset activities when the new regime begins. Firms should not treat the September opening date as the point at which application preparation should start, because a credible authorisation application requires the business model, governance, financial resources, systems and controls, policies and senior management arrangements to be properly developed before submission.

Existing payment firms considering stablecoin products face an additional planning issue. Their future model may require analysis under both the developing cryptoasset regime and the proposed reforms to payment services regulation, which are progressing on related but separate tracks.

A firm intending to launch a hybrid fiat and stablecoin proposition should therefore build its regulatory roadmap around the complete target operating model rather than treating each permission as an isolated application.

The FCA’s new cryptoasset regulatory regime provides the current timetable and information for firms preparing for authorisation.

How Buckingham Capital Consulting can help

Buckingham Capital Consulting has specialised in payment and electronic money regulation since 2013, advising fintech businesses, Payment Institutions and Electronic Money Institutions on FCA authorisation, regulatory structuring and ongoing compliance.

For stablecoin and tokenised payment models, our work focuses on determining how the proposed service interacts with the Payment Services Regulations and electronic money framework, including whether a PI or EMI permission is required, whether an existing firm may need to change its permissions and how customer funds and regulated activities should be structured.

We support firms with regulatory perimeter analysis, Authorised Payment Institution and Electronic Money Institution applications, Variation of Permission applications, stablecoin and tokenised payment models, safeguarding arrangements, financial crime frameworks and FCA regulatory engagement.

Where the wider business model includes cryptoasset issuance, custody, dealing or other activities regulated under the developing UK cryptoasset regime, Regulatory Counsel provides broader specialist support across FCA cryptoasset authorisation and financial regulation.

The most effective point to undertake this analysis is before the technology, banking arrangements and infrastructure partnerships are fixed. A relatively small change in who receives customer money, controls an asset or contracts to provide a service can materially change the permissions required.

Frequently asked questions

Do I need an FCA licence to offer stablecoin payments in the UK?

Potentially. There is no single stablecoin payments licence, and the permissions required depend on what the business actually does. A firm providing regulated payment services may require PI or EMI permissions, while issuing qualifying stablecoins, safeguarding cryptoassets or conducting other regulated cryptoasset activities may require authorisation under the new cryptoasset regime. Some business models may involve both frameworks.

Can an FCA Payment Institution or EMI use stablecoins?

Potentially, but an existing PI or EMI should not assume that its current permissions automatically cover every tokenised payment model. HM Treasury is considering whether firms should require a Variation of Permission before providing payment services using tokenised money. The firm must also assess whether activities such as cryptoasset custody or dealing arise alongside the underlying payment service.

Is a stablecoin the same as electronic money?

No. Although electronic money and stablecoins can both represent digitally stored value and be used for payments, they sit within different regulatory frameworks. Traditional e-money is governed by the electronic money regime, while non-systemic UK-issued qualifying stablecoins will be regulated under the new FCA cryptoasset framework. A single fintech business can potentially use or provide both.

Do I need cryptoasset authorisation if I only use USDC or USDT for settlement?

Not necessarily. The answer depends on how the stablecoin is used and what the firm does. A payment provider using a stablecoin internally as part of its own settlement process may have a different regulatory profile from a platform that enables customers to buy, hold, exchange or transfer stablecoins. The complete customer and asset flow needs to be assessed before the required permissions can be determined.

When do the new UK stablecoin and cryptoasset rules take effect?

The new UK cryptoasset regime is expected to come into force on 25 October 2027, with the FCA application period scheduled from 30 September 2026 to 28 February 2027. Separately, HM Treasury is consulting on how stablecoins and other tokenised forms of money should be integrated into payment services regulation. Firms planning hybrid stablecoin and payment products therefore need to consider both regulatory developments.
