Key takeaways
  • There is no single UK stablecoin licence: a stablecoin payments business may need a payment institution (PI) or e-money institution (EMI) licence, an FCA cryptoasset permission, or both, depending on what it does with customers' money and tokens.
  • The FCA cryptoasset regime starts on 25 October 2027 under the Cryptoassets Regulations 2026 (SI 2026/102); the application window opened on 30 September 2026 and closes on 28 February 2027.
  • The FCA's final stablecoin issuance rules (PS26/10, June 2026) require full backing on statutory trust, redemption at par by the next business day, and a permanent minimum capital of £350,000.
  • Using a stablecoin only as an internal settlement rail behind a GBP transfer is usually a payment service: an authorised PI needs initial capital of €20,000 to €125,000 and an FCA fee of £2,820 or £5,640.
  • HM Treasury's consultation on modernising payment services regulation, including tokenised payments, closed on 6 October 2026; its outcome is awaited and may require existing PIs and EMIs to vary their permission.

Is there a stablecoin licence in the UK?

No single FCA permission is called a stablecoin licence. A business that uses stablecoins for payments may need a payment institution (PI) authorisation, an electronic money institution (EMI) authorisation, a permission under the FCA's new cryptoasset regime, or a combination of these. The answer depends on what the business actually does, not on the technology it uses.

Using stablecoins only as an internal settlement rail is a different service from letting customers buy, hold, transfer and redeem them. The starting point is always a map of the flow of funds: who receives the customer's money, who holds the tokens, who contracts with the customer, and who pays the beneficiary.

Two developments shape the position in late 2026. The FCA published its final rules for UK-issued qualifying stablecoins in June 2026, and its application window for the new regime opened on 30 September 2026. Separately, HM Treasury consulted from 14 July to 6 October 2026 on modernising payment services regulation, including how tokenised payments fit into the payments framework.

The regulated activities that can apply

  • Issuing a qualifying stablecoin in the UK: a new FCA-regulated activity from 25 October 2027.
  • Safeguarding qualifying cryptoassets: holding stablecoins or their private keys for customers.
  • Dealing or arranging: buying, selling or arranging stablecoin transactions for customers.
  • Payment services under the Payment Services Regulations 2017: receiving money to transmit it, running payment accounts, or executing payments, even where stablecoins sit inside the infrastructure.
  • Issuing electronic money under the Electronic Money Regulations 2011.

Words such as blockchain, wallet or USDC do not settle the question. The full journey, from the customer's payment to the beneficiary's receipt, has to be analysed step by step.

When a stablecoin business needs a payment institution licence

A PI authorisation is needed where the underlying service is a regulated payment service. A common example: a firm accepts GBP from a UK customer, moves value across borders using stablecoins, and pays the beneficiary in local currency. The customer sees an international money transfer and never holds a token.

Using a blockchain does not change the regulated activity. Receiving funds from a payer in order to transmit them to a payee is money remittance, whatever rail sits in the middle. The analysis looks at:

  • who receives the customer's funds;
  • who contracts with the customer to provide the transfer;
  • who pays the beneficiary;
  • whether the customer ever holds the stablecoin;
  • whether another regulated firm carries out part of the transaction;
  • whether the business provides the regulated service or only the technology.

What a PI authorisation involves

ItemAuthorised payment institution
Initial capital€20,000, €50,000 or €125,000 depending on the services, set in euros by the Payment Services Regulations 2017
FCA application fee£2,820 or £5,640 depending on the services
Statutory decision period3 months for a complete application, 12 months for an incomplete one
SafeguardingCASS 15, in force since 7 May 2026, with an annual safeguarding audit and a monthly return

The firm plans PI authorisations at 6 to 8 months after submission. Smaller firms with average monthly payment volumes up to €3 million can register as a small payment institution instead, for a £1,130 fee. Our UK payment institution licence page sets out both routes.

When an EMI licence is required

An EMI licence applies where the business issues electronic money: electronically stored monetary value, issued on receipt of funds, which represents a claim on the issuer and is accepted for payments by people other than the issuer. A customer balance in GBP or EUR held in an app and spent or sent later is the typical example.

E-money and stablecoins can look alike, but they are different regulatory products. Fiat balances issued as e-money stay under the Electronic Money Regulations 2011. A UK-issued qualifying stablecoin falls under the FCA cryptoasset regime and the stablecoin issuance rules. One business can use both, for example issuing GBP e-money to customers while settling with partners in stablecoins.

ItemAuthorised EMI
Initial capital€350,000
FCA application fee£5,640 (small EMI registration £1,130)
Statutory decision period3 months for a complete application, 12 months for an incomplete one
SafeguardingCASS 15, with an annual safeguarding audit and a monthly return

The line between the two products should be drawn before the product is built, because changing it later can mean restructuring the entity and its customer terms. Our UK EMI licence page covers the authorisation in full.

Using USDC, USDT or another third-party stablecoin

Using a stablecoin issued by someone else does not by itself decide whether FCA authorisation is needed. What matters is how the stablecoin enters the transaction and what role the business plays.

Internal settlement

At one end, a payment firm uses a stablecoin only inside its own settlement process with a partner abroad. The customer pays and receives fiat, and never holds or sees the token. The regulated activity is the payment service, and the firm holds a PI or EMI permission for it.

Customer-facing stablecoin accounts

At the other end, a platform lets customers convert GBP into stablecoins, hold them in hosted wallets, send them to others and redeem them into fiat. That model raises payments, cryptoasset dealing, custody, safeguarding and financial crime questions together, and usually needs both a payments permission and FCA crypto permissions.

Outsourced infrastructure

Using a stablecoin infrastructure provider does not make a fintech unregulated. The fintech can still be inside the perimeter if it receives customer funds, contracts for the regulated service, controls the assets or carries out regulated transactions itself.

UK-issued and overseas stablecoins

UK law treats a stablecoin issued in the UK differently from one issued overseas. The issuance permission covers issuing a qualifying stablecoin in the UK. An overseas-issued stablecoin, such as a dollar coin issued in the US, can still be traded, held and used in the UK through FCA-authorised firms, which carry the duties for their own activities.

HM Treasury's July 2026 consultation set out proposals for certain regulated stablecoins to work as money within the payments framework, not only as cryptoassets, and asked how overseas stablecoins issued under recognised regimes should be treated. The consultation closed on 6 October 2026 and HM Treasury is analysing the responses, so the final position on overseas coins in payments is not yet settled.

When choosing which stablecoins and partners to use, firms should weigh the issuer's regulatory status and the token's role in the customer journey, alongside liquidity, technology and adoption.

Five common stablecoin payment models and the permissions they need

1. Cross-border transfers on a stablecoin rail

A UK customer pays GBP, the firm converts to a dollar stablecoin, sends it to a partner abroad, and the partner pays the beneficiary in local currency. The customer never holds a token. This is money remittance and needs PI authorisation, or SPI registration for smaller volumes. The conversion and transfer of tokens is the firm's own treasury activity, though the partner abroad needs its own local licence.

2. Business accounts holding stablecoin balances

A platform offers companies an account in which they hold dollar stablecoins alongside GBP and EUR balances, and send either to suppliers. The fiat balances are e-money or payment accounts and need EMI or PI authorisation. Holding the stablecoins for the client is custody, and buying them for the client is dealing or arranging, which need FCA crypto permissions from 25 October 2027.

3. Merchants accepting stablecoins and settling in GBP

A processor lets online shoppers pay in stablecoins and pays the merchant in pounds. Receiving value for the merchant and paying out is a payment service, typically merchant acquiring, needing a PI permission. Where the processor exchanges the tokens for the merchant as principal, the dealing permission applies too.

4. Payouts to contractors abroad

A payroll platform takes GBP from UK employers and pays overseas contractors, who can choose to receive stablecoins into their own wallets. The collection and payout is a payment service. Paying out in tokens the platform buys for the contractor brings in dealing or arranging, and holding the tokens before payout brings in custody.

5. On-ramp and off-ramp services

A business that sells stablecoins to customers for pounds and buys them back is dealing in qualifying cryptoassets and, if it holds the tokens, safeguarding them. It needs FCA crypto permissions from 25 October 2027 and remains subject to the Money Laundering Regulations registration until then. Where it also holds fiat balances for customers between trades, those balances need EMI or PI protection.

In each model the permission follows the step that touches the customer's money or tokens. A firm that runs several models should map each one separately before deciding which entity holds which permission.

Financial crime, safeguarding and promotions

Safeguarding the fiat leg

Fiat money a PI or EMI receives for a payment, or in exchange for e-money, is protected under CASS 15. The rules have been in force since 7 May 2026 and bring a monthly safeguarding return and an annual safeguarding audit. Stablecoins held for customers are not protected under CASS 15; from 25 October 2027 they come under the FCA's cryptoasset custody rules. A hybrid product needs both sets of controls, and the reconciliation must show at all times which customer money is in fiat and which in tokens.

Money laundering controls

Cryptoasset businesses already apply the travel rule under the Money Laundering Regulations, passing the originator's and beneficiary's details with each cryptoasset transfer. The FCA expects blockchain analytics to trace where tokens have come from, wallet screening against sanctions lists, a business-wide risk assessment that covers stablecoin flows, and suspicious activity reporting to the National Crime Agency. A payments firm adding stablecoins should extend its existing controls to on-chain activity before launch, not after.

Financial promotions

Marketing a cryptoasset product to UK consumers is subject to the FCA's financial promotion rules, including risk warnings, a cooling-off period for first-time investors and appropriateness checks. A payments product that lets customers hold or exchange stablecoins should be reviewed against these rules as well as the Consumer Duty.

The FCA's final rules for UK stablecoin issuers

The FCA published its final rules for issuing qualifying stablecoins in Policy Statement PS26/10 in June 2026, and the prudential rules in PS26/12. They apply from 25 October 2027 to any firm issuing a qualifying stablecoin in the UK.

  • Full backing for every token minted, in the reference currency, held on a statutory trust for holders, with a separate trust for each stablecoin.
  • Liquid core: on-demand deposits and core backing assets of at least the higher of 5% or the largest daily redemption over the previous 180 redemption days.
  • Redemption at par for any amount by the end of the next business day after the issuer receives the token.
  • Custody under CASS 16: signed acknowledgement letters from each custodian, daily internal and external reconciliations, and a 20% limit on group custodians unless justified.
  • Disclosures updated at least every three months, with an annual independent review of the 1:1 backing.
  • No interest from the backing pool passed to holders, directly or through third parties.
  • Capital: own funds of at least the highest of £350,000, the fixed overheads requirement and 1% of coins in issue.

Stablecoins that HM Treasury recognises as systemic, because they are widely used for payments, come under joint Bank of England and FCA supervision, with the Bank setting the rules for sterling systemic stablecoins.

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

Not automatically. A PI or EMI permission covers the payment services and e-money it lists, not every tokenised model. HM Treasury's consultation proposed that authorised and registered payment firms obtain a variation of permission before providing payment services with tokenised money.

Stablecoin services also bring technology, custody, liquidity, redemption, financial crime and third-party dependency risks that fiat models do not. An existing firm should compare the new product with its current permissions and check:

  • whether customers will hold cryptoassets;
  • whether custody, exchange or dealing is involved;
  • how the flow of funds changes, and where funds sit overnight;
  • whether the change creates a new regulated activity.

Safeguarding arrangements under CASS 15, financial crime controls, governance, operational resilience and outsourcing oversight may all need updating. Where a new permission is needed, it is added through a variation of permission application; the FCA fee is £1,410 or £565 depending on the change. A crypto activity under the new regime needs its own FSMA permission, applied for in the current window.

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

Possibly, but not automatically. The UK framework aims to avoid duplicate authorisation, and HM Treasury has been considering how a stablecoin issuance permission interacts with the payments rules when stablecoins are used to make payments.

An issuance permission does not cover everything. Running payment accounts, money remittance, merchant acquiring, card issuing or fiat payments may still need a payments permission. Cryptoasset activities beyond issuance, such as custody, dealing or arranging, each need their own permission. The analysis covers the whole business, not only its main product.

Stablecoin wallets and custody

The word wallet covers very different models. A non-custodial wallet, where only the customer controls the private keys, is a software product. A hosted wallet, where the provider controls the assets for the customer, is custody.

From 25 October 2027, safeguarding qualifying cryptoassets for customers is a regulated activity, with a permanent minimum capital of £150,000 and the FCA's custody rules. Where stablecoins are held only briefly as part of a regulated payment transaction, HM Treasury has aimed to reduce overlap between the custody and payments rules, and the outcome of its consultation will confirm how.

Payment and custody permissions are not interchangeable. Who controls the assets, and why they are held, remain the central questions.

The most efficient route for a new stablecoin payments fintech

An early-stage firm does not always need every permission itself. It can use regulated partners for fiat accounts, payment execution, conversion, custody or card issuing, while owning the customer experience and the technology.

A partner model has to be designed with care. Using an authorised provider underneath does not on its own keep the fintech outside the perimeter. The key questions are:

  • who contracts with the customer;
  • who receives or controls the funds;
  • who performs each regulated activity;
  • what the fintech tells customers about its role.

The structure should be settled before infrastructure providers are chosen and contracts signed. Once integrations and agreements are in place, changing who does what is slower and more expensive.

Where payments and cryptoasset permissions overlap

Stablecoins are now a payments question as much as a cryptoasset question. A business can sit in the payments framework, the cryptoasset regime, or both, depending on what it does rather than how it describes itself.

The order of work that gives a reliable answer:

  1. Map the customer journey and the flow of funds and tokens.
  2. Identify which entity performs each step.
  3. Decide which steps are regulated activities, and under which regime.
  4. Choose which permissions to hold directly and which functions partners will perform.
  5. Plan the applications and their timing as one programme.

Firms that issue or operate in other markets too can compare the UK position with the US, EU and Asian regimes in our global stablecoin licence guide.

The authorisation timetable

DateMilestone
4 February 2026Cryptoassets Regulations 2026 (SI 2026/102) made
7 May 2026CASS 15 safeguarding rules for PIs and EMIs in force
June 2026FCA final rules for the crypto regime, including PS26/10 on stablecoin issuance
14 July to 6 October 2026HM Treasury consultation on modernising payment services regulation
30 September 2026FCA application window for the crypto regime opened
28 February 2027Application window closes
25 October 2027Crypto regime commences

The window is open now. The FCA will review window applications in the order received and aims to decide them before 25 October 2027, so an early, complete file gives the most time for questions. A credible application needs the business model, governance, capital, systems, policies and senior team in place.

Existing payment firms may need to work on both tracks: a crypto permission under the new regime, and any variation of their PI or EMI permission that follows HM Treasury's payments reforms. A hybrid fiat and stablecoin product is best planned as one operating model covering both. Our page on UK cryptoasset authorisation sets out the application file.

How Buckingham Capital Consulting helps

The firm has specialised in payment and e-money regulation since 2013, working with fintechs, PIs and EMIs on authorisation, structure and ongoing compliance. For stablecoin and tokenised payment models it covers:

  • perimeter analysis under the Payment Services Regulations, the e-money rules and the new cryptoasset regime;
  • whether a PI, EMI or crypto permission is needed, and which entity should hold it;
  • PI and EMI applications, and variations of permission for existing firms;
  • FCA crypto regime applications in the current window;
  • CASS 15 safeguarding, financial crime frameworks and FCA engagement.

The analysis is most valuable before the technology, banking and infrastructure arrangements are fixed.

Frequently asked questions

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

Usually yes, but there is no single stablecoin licence. Payment services need a PI or EMI permission, and issuing, holding or dealing in stablecoins for customers needs FCA cryptoasset permissions from 25 October 2027; some models need both.

Can an FCA payment institution or EMI use stablecoins?

It can, but its current permission may not cover every tokenised model. HM Treasury has proposed a variation of permission for tokenised payment services, and custody or dealing alongside the payment service needs its own crypto permission.

Is a stablecoin the same as electronic money?

No. Fiat e-money balances fall under the Electronic Money Regulations 2011, while a UK-issued qualifying stablecoin falls under the FCA cryptoasset regime and the PS26/10 issuance rules.

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

Not necessarily. If customers pay and receive fiat and never hold the token, the regulated activity is usually the payment service; letting customers buy, hold or transfer stablecoins brings in the crypto permissions.

When do the new UK stablecoin rules take effect?

On 25 October 2027. The FCA application window runs from 30 September 2026 to 28 February 2027.

What capital does a UK stablecoin issuer need?

Own funds of at least the highest of £350,000, the fixed overheads requirement and 1% of the value of coins in issue, under PS26/12.

What is the status of HM Treasury's payments consultation?

The consultation on modernising payment services regulation ran from 14 July to 6 October 2026. HM Treasury is analysing responses, and the outcome will confirm how tokenised payments fit into the payments rules.
