UK Reworks Stablecoin Payments Perimeter Ahead of the 2027 Crypto Regime
The UK is redrawing the boundary between crypto regulation and payments regulation for stablecoins before its new financial-services regime becomes fully operational.
On 15 September 2026, HM Treasury laid the draft Financial Services and Markets Act 2000 (Cryptoassets) (Miscellaneous Amendments) Regulations 2026 before Parliament. The amendments are intended to remove certain payment activities involving UK-issued qualifying stablecoins from the new crypto dealing and arranging perimeter while the government develops a separate future payments framework for stablecoins.
The distinction is important. Stablecoin issuance itself remains a regulated cryptoasset activity, and safeguarding UK qualifying stablecoins for customers would continue to require the relevant crypto permission during the interim period. Lending and borrowing involving those stablecoins would also remain within the crypto dealing perimeter.
The September instrument is not yet operative law. As of 26 September 2026, it is subject to the draft affirmative procedure and has been laid before both Houses of Parliament, with parliamentary approval still required.
For stablecoin issuers, payment providers, custodians, fintech groups and cross-border businesses preparing for the FCA’s October 2027 crypto regime, the result is a more complicated but potentially more proportionate regulatory architecture: issuance under the crypto regime, payments moving toward dedicated payments regulation, and custody and lending remaining regulated according to the activity being performed.
For readers’ convenience, we have placed the key Treasury, FCA and parliamentary materials at the end of this article.

Why the UK is changing the stablecoin perimeter before 2027
The Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 established the main statutory architecture for the UK’s future cryptoasset regime.
Most of that regime comes fully into force on 25 October 2027. It creates regulated activities covering areas such as qualifying stablecoin issuance, cryptoasset safeguarding, trading platforms, dealing, arranging and staking.
The problem identified by HM Treasury is that a business using stablecoins as a means of payment may also fall within the new dealing or arranging activities.
That could require a stablecoin payment provider to obtain crypto permissions in 2027 even though the government intends to create a dedicated payments framework for stablecoins shortly afterwards.
HM Treasury says it wants to avoid this duplication where possible.
The payments regime is still being developed
The government intends to modernise UK payments legislation more broadly and incorporate certain stablecoin payment services into that framework.
In particular, Treasury plans to consult on bringing payment services using UK-issued qualifying stablecoins into regulated payments.
This future payments reform has not yet replaced the crypto framework.
The September amendments are therefore designed as a bridge between two regulatory stages:
- the FSMA crypto regime beginning in October 2027; and
- the future stablecoin payments regime still being developed.
For firms designing business models now, that distinction is critical.
What is a UK qualifying stablecoin?
The 2026 crypto framework defines a qualifying stablecoin as a qualifying cryptoasset that seeks or purports to maintain a stable value by reference to a fiat currency and meets the applicable statutory conditions.
The regulated activity of issuing a qualifying stablecoin focuses on issuance from a UK establishment where the issuer, among other things, undertakes or arranges redemption and holds or arranges the holding of assets intended to maintain the token’s stable value.
For the September reform, Treasury uses the shorthand UKQS — UK qualifying stablecoin for stablecoins issued in the UK by a firm authorised for the new stablecoin issuance activity.
That UK issuance element matters because the proposed payments carve-out is not a general exemption for all stablecoins used in the UK.
UK stablecoin payments would be carved out of crypto dealing and arranging
The central proposal is to remove specified transactions involving UK-issued qualifying stablecoins from three of the new cryptoasset regulated activities:
- dealing in qualifying cryptoassets as principal;
- dealing in qualifying cryptoassets as agent; and
- arranging deals in qualifying cryptoassets.
The policy objective is to stop an ordinary stablecoin payment from being treated as crypto dealing or arranging merely because a qualifying stablecoin moves between parties.
The carve-out is designed around payments
Treasury’s rationale is that a UK qualifying stablecoin issued by an FCA-authorised issuer will already sit within a regulated issuance framework.
The government therefore intends eventually to regulate the payment service involving that token through payments legislation rather than forcing providers into overlapping crypto dealing permissions.
This is an important structural decision.
The UK is not proposing to treat a qualifying stablecoin simply as conventional electronic money. Instead, it is building separate regulatory layers around:
- issuance;
- safeguarding;
- use for payments;
- dealing and arranging; and
- lending and borrowing.
A firm may therefore need different permissions depending on what it actually does with the token.
Stablecoin issuance remains regulated under the crypto regime
The amendments do not remove stablecoin issuers from FCA regulation.
Issuing qualifying stablecoin remains one of the core regulated cryptoasset activities under the future FSMA framework.
The FCA published its final stablecoin issuance rules on 30 June 2026.
Those rules address areas including:
- backing assets;
- safeguarding of backing assets;
- redemption;
- disclosures to holders; and
- prudential requirements.
The policy distinction is therefore between issuing the stablecoin and using an already issued stablecoin to make payments.
Issuers still need FCA authorisation
A UK business intending to issue a qualifying stablecoin will need the corresponding FSMA permission once the regime is fully operational.
The FCA authorisation gateway opens on 30 September 2026, allowing prospective issuers and other crypto firms to submit applications well before October 2027.
The payment carve-out should therefore not be interpreted as an alternative route around stablecoin issuer authorisation.
Safeguarding remains regulated during the interim period
The proposed dealing and arranging carve-out does not remove custody from the crypto perimeter.
Treasury expressly states that firms providing UK qualifying stablecoin payment services may still need permission for safeguarding cryptoassets where they hold or arrange for another person to hold stablecoins on behalf of customers.
This is likely to be one of the most practically important issues for payment providers.
A payment firm may avoid dealing permission but still need custody permission
Consider a business that enables merchants to receive payments in a UK qualifying stablecoin.
If its role falls within the proposed payment carve-out, it may avoid the need for dealing or arranging permission for that transaction.
However, if the business holds customer stablecoins, controls wallets or arranges custody on behalf of customers, the safeguarding activity may still require FCA permission.
The regulatory analysis must therefore follow the full transaction flow, not simply the commercial description “stablecoin payment service”.
Safeguarding may ultimately move into the payments framework
Treasury says it intends to consult on moving safeguarding undertaken in the course of stablecoin payment services into the future payments regime.
Until that reform is completed, however, safeguarding remains within the crypto regime.
The government acknowledges that this creates an interim regulatory friction but considers FCA supervision necessary to protect consumers during the transition.
For businesses entering the market in 2027, this creates a possible two-stage regulatory journey: crypto safeguarding authorisation first, followed by migration into the future payments regime once that framework is implemented.
Treasury wants to narrow the settlement exclusion
The existing cryptoasset framework contains an exclusion from safeguarding where cryptoassets are held temporarily to facilitate settlement of a transaction.
Treasury says this exclusion was intended principally for trade settlement — for example, where a dealer or trading platform briefly holds customer assets to complete a transaction.
However, the existing wording could potentially be interpreted more broadly and allow certain stablecoin payment providers to argue that their temporary holding of stablecoins falls outside safeguarding regulation.
The September amendments seek to clarify that the exclusion applies where the holding is ancillary to dealing or arranging.
It would therefore not generally remove stablecoins held as part of a standalone payment service from the safeguarding perimeter.
This point should be considered carefully by wallet providers and payment intermediaries that temporarily take control of customer assets.
Stablecoin lending and borrowing stay inside the crypto perimeter
Treasury is deliberately taking a different approach to lending.
The proposed carve-out for UK qualifying stablecoins does not extend generally to lending and borrowing activities.
The government considers these products capable of creating consumer risks that justify FCA regulation.
This means a stablecoin can be treated differently depending on how it is used:
- ordinary payment activity may benefit from the proposed dealing/arranging carve-out;
- lending or borrowing the same token may remain within the crypto regulatory perimeter.
Collateral arrangements remain an unresolved issue
Treasury recognises that keeping stablecoin lending and borrowing within dealing could create friction where stablecoins are used as collateral.
The government has said it intends to consider how such barriers can be mitigated before the instrument is finalised.
This is an important point for institutional markets.
Stablecoins may be used not only for retail payment flows but also for settlement, liquidity management and collateralisation. A rule designed around consumer lending could affect transactions with very different economic functions.
The final drafting therefore remains worth monitoring closely.
Overseas-issued stablecoins receive different treatment
The proposed carve-out focuses on UK-issued qualifying stablecoins.
Stablecoins issued overseas may remain within the crypto dealing and arranging perimeter when used in UK-facing payment services, depending on how the transaction is structured.
Treasury acknowledges that this could create friction for cross-border payments.
Cross-border providers need a separate perimeter analysis
A UK payment provider might therefore face different regulatory outcomes depending on whether it supports:
- a stablecoin issued by a UK authorised qualifying stablecoin issuer; or
- an overseas-issued stablecoin.
This could affect product architecture, token selection and issuer partnerships.
For global payment businesses, the difference is significant because cross-border payments are one of the principal commercial use cases for stablecoins.
Treasury says it intends to examine this issue further with industry.
Financial promotions would also change
The amendments also seek to align the financial promotions perimeter with the new treatment of UK qualifying stablecoin payments.
Treasury says transactions involving only UK qualifying stablecoins would generally be removed from the cryptoasset financial promotions perimeter where they fall within the proposed carve-out.
Lending and borrowing arrangements would remain treated differently.
At the same time, the regulated activity of issuing a qualifying stablecoin is being added to the relevant financial promotions framework.
This reinforces the distinction between promoting a regulated issuance product and facilitating a routine payment using a token already issued within the authorised framework.
Businesses should nevertheless avoid assuming that every communication involving a qualifying stablecoin becomes unregulated. The activity, product and structure of the promotion still need to be assessed against the final rules.
Stablecoin backing assets would receive earlier investment-fund exclusions
The September package also addresses an issue that is less visible but potentially important for stablecoin issuers.
The existing 2026 crypto legislation contains provisions designed to prevent certain assets held to back qualifying stablecoins from being treated as a collective investment scheme or alternative investment fund merely because of the stablecoin reserve structure.
Treasury proposes bringing those exclusions into effect earlier rather than waiting for the entire crypto regime to commence in October 2027.
The purpose is to reduce unnecessary regulatory uncertainty around reserve structures and allow stablecoin use cases to develop before full commencement.
For issuers designing reserve trusts, custodial arrangements or treasury structures, this is a technically important part of the package.
MLR registration may still apply during the transition
The amendments also do not eliminate the existing UK AML framework for crypto businesses.
Treasury states that firms providing only UK qualifying stablecoin services and not holding a relevant FSMA permission may still need to register with the FCA under the Money Laundering Regulations.
The interaction with the FCA authorisation gateway therefore needs careful planning.
A business may need to consider:
- current MLR registration;
- future FSMA stablecoin or safeguarding permission;
- the proposed stablecoin payment carve-out; and
- the later transition into a revised payments regime.
This is another reason why stablecoin market entry should be mapped as a regulatory timeline rather than a single licensing application.
The FCA has already finalised its stablecoin issuer rules
The September Treasury amendments are occurring against a regulatory framework that is already relatively advanced.
On 30 June 2026, the FCA published final rules for the new cryptoasset regime, including specific rules for qualifying stablecoin issuers.
The final framework includes requirements relating to stablecoin backing assets and their safeguarding, redemption and disclosures.
The FCA also confirmed broader prudential requirements for regulated crypto firms.
Systemic stablecoins can face an additional Bank of England layer
Also on 30 June, the FCA and Bank of England published their approach to the joint regulation of stablecoin issuers recognised as systemic.
An issuer would initially operate under FCA regulation and could move into joint FCA/Bank supervision if HM Treasury later recognises it as systemic.
This means the emerging UK structure potentially has three distinct regulatory dimensions:
- FCA crypto regulation for qualifying stablecoin issuance and relevant crypto activities;
- future payments regulation for payment services using qualifying stablecoins; and
- Bank of England involvement where a stablecoin becomes systemically important.
This layered approach should be considered by businesses planning for large-scale issuance or payment adoption.
The amendments are still before Parliament
The legal status of the September instrument needs particular care.
The Financial Services and Markets Act 2000 (Cryptoassets) (Miscellaneous Amendments) Regulations 2026 were laid before the House of Commons and House of Lords on 15 September 2026.
They are subject to the draft affirmative procedure.
As of 26 September 2026, Parliament’s procedure tracker records the instrument as still before Parliament. The Secondary Legislation Scrutiny Committee also lists it among instruments awaiting scrutiny.
Accordingly, the changes described in this article should be treated as the government’s proposed amendments rather than existing operative law.

What stablecoin businesses should assess now
The September changes make regulatory mapping more important, not less.
UK stablecoin issuers
Issuers should continue preparing for FCA authorisation under the dedicated qualifying stablecoin activity.
The proposed payment carve-out does not remove issuer regulation.
Reserve architecture, redemption, disclosures, governance, prudential resources and safeguarding of backing assets remain central.
Stablecoin payment providers
Payment firms should map the entire flow of assets.
Questions include:
- Is the stablecoin UK-issued?
- Is the issuer FCA-authorised?
- Does the payment provider deal or arrange?
- Does it safeguard the customer’s stablecoin?
- Is holding temporary or part of the payment service?
- Does the model involve lending or collateral?
- Are overseas stablecoins also supported?
The answers can determine whether one or several regulatory permissions are required.
Custodians and wallet providers
Custody remains particularly important during the transition.
A firm should not assume that receiving a stablecoin payment carve-out removes the need for safeguarding authorisation where it controls customer assets or arranges custody.
Cross-border payment businesses
Overseas-issued stablecoins may not benefit from the same carve-out.
Businesses offering global stablecoin rails should therefore test UK perimeter exposure token by token and transaction flow by transaction flow.
Lending and treasury businesses
Stablecoin lending and borrowing remain within Treasury’s intended crypto regulatory perimeter.
Businesses using UK qualifying stablecoins for financing or collateral should pay particular attention to the final drafting because Treasury has explicitly recognised potential friction in this area.

UK Stablecoin Payments Regulation FAQ
Has the UK already removed stablecoin payments from crypto regulation?
No.
HM Treasury has laid a draft statutory instrument proposing targeted exclusions for certain payment activity involving UK-issued qualifying stablecoins.
As of 26 September 2026, th
Will issuing a UK qualifying stablecoin still require FCA authorisation?
Yes.
Issuing qualifying stablecoin remains a regulated activity under the future FSMA crypto framework.
The proposed amendments primarily address how subsequent payment transactions involving UK qualifying stablecoins interact with dealing and arranging rules.
Which crypto activities would the stablecoin payment carve-out affect?
The proposal would carve qualifying transactions involving UK qualifying stablecoins out of:
- dealing as principal;
- dealing as agent; and
- arranging deals.
The exclusion is intended primarily to reduce duplicative regulation of stablecoin payment services.
Will a stablecoin payment provider still need custody permission?
Potentially, yes.
Where the firm safeguards UK qualifying stablecoins, or arranges safeguarding on behalf of another person, the relevant crypto safeguarding permission may still be required during the interim regime.
Will stablecoin custody eventually move into payments regulation?
Treasury intends to consult on bringing safeguarding carried out as part of stablecoin payment services into the future payments framework.
That reform has not yet been completed.
Are stablecoin lending and borrowing excluded from crypto regulation?
No.
Treasury intends lending and borrowing involving UK qualifying stablecoins to remain within the relevant crypto dealing perimeter so the FCA can address associated consumer risks.
Are overseas stablecoins covered by the proposed payments carve-out?
Not generally on the same basis.
The proposal focuses on UK-issued qualifying stablecoins. Treasury acknowledges that overseas-issued stablecoins may continue to create crypto dealing or arranging issues for cross-border payment services.
Will UK qualifying stablecoin payments remain subject to crypto financial promotion rules?
The government proposes aligning the financial promotions perimeter with the payment carve-out.
Transactions involving only UK qualifying stablecoins would generally be excluded from the relevant crypto promotions treatment, except for specified lending and borrowing arrangements.
When does the main UK crypto regime begin?
The principal provisions of the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 are scheduled to come fully into force on 25 October 2027.
When can stablecoin issuers apply for FCA authorisation?
The FCA crypto authorisation gateway opens on 30 September 2026.
Businesses intending to issue qualifying stablecoins or conduct other regulated cryptoasset activities can begin submitting the relevant applications from that date.
