Description: BoE systemic stablecoin rules explained: the £40bn issuance guardrail, 70/30 backing split, FCA transition and what UK issuers must prepare for reporting.

Jurisdictions: UK

Last updated: June 2026

Get the timing of the UK stablecoin perimeter wrong and you build the wrong thing. A firm that designs its reserve model around a 60% gilt ceiling, or around per-coin holding caps it has to police at the wallet level, is building to a draft the BoE systemic stablecoin rules have now moved past. On 22 June 2026 the Bank of England published its policy statement and draft Code of Practice for sterling-denominated systemic stablecoins. The headline numbers changed from the November 2025 consultation, and the supervisory tools changed with them. If you are an issuer, a payment institution eyeing stablecoin rails, or an e-money firm watching the gateway, the BoE systemic stablecoin rules now set out a different shape of obligation than the one the market spent the winter modelling.

The short version: the Bank dropped the individual and business holding limits it consulted on. It replaced them with a single temporary issuance guardrail set at £40 billion per systemic stablecoin. It raised the share of backing assets that can sit in interest-bearing UK government debt from 60% to 70%. And it gave the market a feedback window that closes on 22 September 2026, with the Code of Practice intended to be finalised by the end of 2026 and regulated systemic stablecoins able to operate from 2027.

None of that means a systemic stablecoin operator can start filing tomorrow. The Bank’s systemic obligations attach only once HM Treasury makes a recognition order. The draft Code contains core prudential, notification and record-keeping requirements, while the Bank expects to consult in 2027 on any further updates needed for disclosures, reporting and record-keeping. What follows is what the framework requires today, where it sits in UK statute, and the traps that come from treating the consultation and the policy statement as the same document.

Why the BoE systemic stablecoin rules sit in two different statutes

The legal plumbing here trips people up because it is split across two Acts and two regulators, and the stablecoin itself does nothing to trigger any of it. The trigger is a decision by HM Treasury.

The Financial Services and Markets Act 2023 expanded the Bank of England’s remit to cover what the legislation calls digital settlement assets, or DSAs. A DSA is defined in Schedule 6 to FSMA 2023 as a digital representation of value or rights, whether or not cryptographically secured, that can be used for the settlement of payment obligations, can be transferred, stored or traded electronically, and uses technology supporting the recording or storage of data, which may include distributed ledger technology. Stablecoins fall inside that definition, but so could other instruments. The category is deliberately wide.

The supervisory powers themselves live in Part 5 of the Banking Act 2009, as amended by FSMA 2023. Part 5 is the same regime the Bank already uses to oversee recognised interbank payment systems. FSMA 2023 extended it so that a payment system using DSAs, and the service providers to such a system, can be brought into the same supervisory perimeter. The Bank supervises systemic DSA payment systems and systemic DSA service providers under that Part 5 machinery once a recognition order has been made.

That recognition order is the hinge. HM Treasury, not the Bank, decides whether a particular stablecoin arrangement is systemic. HM Treasury must consult the Bank and relevant regulators before making the order; the Bank’s 2025 consultation stated that this includes the FCA and the Payment Systems Regulator where relevant. Until that order exists, a stablecoin is not a systemic stablecoin in the legal sense, no matter how large it gets, and the Code of Practice does not bite on it.

Firms misread their own position here. The Bank’s regime is the systemic layer. The conduct, authorisation and firm-level prudential layer for stablecoins that are not systemic sits with the Financial Conduct Authority, which consulted on firm-level conduct, safeguarding and prudential requirements for those activities in CP25/14 on stablecoin issuance and cryptoasset custody, alongside the prudential consultation CP25/15; final FCA rules are still expected through policy statements ahead of commencement of the new cryptoasset regime. Once a stablecoin is recognised as systemic, the arrangement is dual regulated: the Bank for prudential and financial-stability purposes, the FCA for conduct, with the PSR retaining its competition interest. A firm does not graduate out of the FCA’s reach when it becomes systemic. It acquires a second supervisor.

What changed between the November 2025 consultation and the June 2026 policy statement

The single most important thing to understand about the current BoE systemic stablecoin rules is that the November 2025 consultation paper and the June 2026 policy statement are not interchangeable. Several of the figures that circulated for months were superseded on 22 June 2026.

The November 2025 consultation, “Proposed regulatory regime for sterling-denominated systemic stablecoins,” proposed temporary per-coin holding limits of £20,000 for individuals and £10 million for businesses. That consultation closed on 10 February 2026. The holding-limit design was the part of the proposal that drew the loudest objections, because it would have forced issuers and their distribution partners to track and cap balances at the level of each individual holder.

The policy statement removed those holding limits. In their place the Bank introduced a temporary issuance guardrail applied to each systemic stablecoin, initially set at £40 billion. The Bank’s stated logic is that the guardrail protects the supply of credit to the economy, which was the original purpose of the holding limits, while being cheaper and easier to operate and allowing unrestricted use by households and businesses. The guardrail is to be reviewed regularly and removed once the Bank is satisfied that the risks to credit provision have been addressed.

The backing-asset rule also shifted. The consultation proposed that up to 60% of backing assets could sit in short-term UK government debt, with the remainder in unremunerated central bank deposits. The policy statement raised that ceiling so that up to 70% may now be held in short-term UK government debt, with at least 30% in unremunerated Bank of England deposits. That ten-point move matters more than it looks, because central bank deposits pay nothing, so the gilt allocation is where any return on the reserve comes from. The change was the Bank’s largest single accommodation to industry feedback on viability.

If your internal documentation still cites the £20,000 holding limit or the 60% gilt ceiling as live requirements, it is describing the consultation, not the regime. That is the most common error I expect to see in early gap analyses: teams lifting figures from the winter law-firm alerts without checking which document they came from.

The backing-asset and reserve model issuers have to build to

The reserve is the centre of gravity for any systemic stablecoin operator, and it is where the reporting will be heaviest, so it is worth being precise about what the framework requires.

Under the policy statement, the backing assets for a systemic stablecoin must be held as a mix of unremunerated deposits at the Bank of England and short-term sterling UK government debt. The interest-bearing portion, the gilts, is capped at 70%. At least 30% must sit in the Bank’s unremunerated account. That account is what underwrites redemption under stress, because it gives the issuer access to genuinely risk-free, instantly available central bank money rather than relying on selling gilts into a falling market on the day everyone redeems at once.

There is a step-up concession layered on top. The draft Code allows issuers recognised by HM Treasury as systemic at launch, and issuers transitioning to systemic status from the FCA non-systemic regime, to hold up to 95% of backing assets in sterling-denominated UK government debt securities as they scale, with the percentage gradually reduced to the standard steady-state ceiling once the stablecoin reaches a scale where this is appropriate. The detailed mechanics of how a firm moves from FCA solo regulation into joint Bank-FCA regulation are separate and will be addressed in the forthcoming Bank-FCA joint regulatory approach.

The custody and trust requirements carried over from the consultation. Backing assets are to be held on statutory trust, so that coinholders have a protected claim if the issuer fails. Where assets are not held directly with the Bank, the issuer is required to appoint a qualified third-party custodian that is a separate legal entity and authorised and regulated in the UK. Self-custody of the reserve is not the model the framework contemplates for the gilt portion.

The reserve rule does not mean an issuer can treat 70% as a target to maximise. It is a ceiling, not an allocation instruction. The framework leaves the issuer responsible for liquidity management within that envelope, and a reserve that runs permanently at the 70% gilt cap has thinner same-day liquidity than one that holds more at the Bank. The number a reporting team will have to evidence is not just composition on a given date but the issuer’s ability to meet redemption demand, which is a different question.

Redemption, capital and the obligations behind the returns

Two firm-level requirements sit underneath the reserve and will drive much of what gets reported: redemption and capital.

On redemption, the June 2026 policy statement and draft Code move the operational deadline to a rolling 24-hour standard. A systemic issuer must process redemption requests as soon as practicable and, in any event, within 24 hours of receiving a full redemption request. A full redemption request is received only once the issuer has the redemption request, has completed AML/KYC checks, and has received the coins in its wallet from the coinholder. Redemption remains at face value without undue constraint or cost; any fees must be fair, transparent and proportionate, and may only be deducted with the coinholder’s consent.

On capital, the June 2026 policy statement sets the minimum capital requirement at the higher of two figures: six months of the issuer’s relevant operating expenses, or the cost of executing its recovery plan and orderly wind-down plan, excluding costs already provided for in the wind-down reserve. The issuer must notify the Bank if its capital falls below 110% of that minimum requirement. This is a general business-risk buffer for recovery and orderly wind-down, not a credit-risk capital charge in the CRR sense. UK banks should not map it mechanically onto their own funds stack. It is a different instrument doing a different job.

The reporting consequence of all this is that a systemic stablecoin operator is not filing one return. It is evidencing reserve composition, reserve liquidity, redemption performance, capital adequacy against the business-risk standard, and operational resilience. The specific reporting templates, frequencies and remittance dates are not fixed. The draft Code contains core rules, notification and record-keeping expectations, and the Bank expects to consult in 2027 on any further updates needed for disclosures, reporting and record-keeping. Anyone who tells you the precise return names and remittance dates today is guessing. The honest position for a reporting team is to map the data domains now and wait for the final requirements for the form numbers.

For the wider UK reporting context that systemic firms already operate inside, our note on the Bank of England and FCA memorandum of understanding on UK financial market infrastructure shows how the two regulators already split supervisory data for dual-regulated entities.

Where the FCA regime ends and the Bank’s begins

The hand-off between the FCA and the Bank is the part of this framework most likely to be mishandled operationally, because a firm can cross it without choosing to.

Issuing a qualifying stablecoin and safeguarding qualifying cryptoassets are becoming regulated activities under FSMA. A firm must be FCA-authorised to carry them on in the UK. The FCA consulted on firm-level conduct, safeguarding and prudential requirements for those activities in CP25/14 and CP25/15; final FCA rules are still expected through policy statements ahead of commencement of the new cryptoasset regime. The wider cryptoasset regime is scheduled to commence on 25 October 2027, with a gateway window and transitional arrangements for firms that apply in time.

A non-systemic stablecoin issuer lives entirely in the FCA world. Nothing in the Bank’s Code of Practice applies to it. The complication is growth. If a stablecoin becomes widely used in payments and HM Treasury recognises it as systemic, the issuer moves into the dual-regulated layer, and the Bank’s reserve, guardrail, redemption and capital expectations attach on top of the FCA requirements it already meets. The Bank and the FCA have said they are working to deliver an end-to-end regime, including a managed transition as firms grow from non-systemic to systemic. The 95% step-up allowance applies both to systemic-at-launch issuers and to issuers transitioning to systemic status from the FCA regime, reducing to the standard steady-state ceiling once the stablecoin reaches a scale where this is appropriate; the detailed mechanics of how a firm moves from FCA solo regulation into joint Bank-FCA regulation are still to be set out in the forthcoming joint regulatory approach.

The error to avoid is treating systemic status as a binary the firm controls. It is a determination HM Treasury makes about the arrangement, after consulting the Bank and the PSR, rather than a license the issuer applies for. A reporting function in a fast-growing issuer should be building the systemic-layer data capability before the recognition order, not after, because the order does not come with a long grace period for standing up new returns.

How the UK regime diverges from MiCAR and why the divergence matters

UK firms with EU operations, or EU firms looking at the UK, need to hold two regimes in their heads at once, and the divergence is real rather than cosmetic.

In the EU, sterling-style stablecoins fall under the Markets in Crypto-Assets Regulation as e-money tokens or asset-referenced tokens, with the European Banking Authority and national competent authorities supervising issuers and the reserve rules set in the regulation itself. The UK has not adopted MiCAR and is not onshoring it. The UK perimeter is built on FSMA 2023, the Banking Act 2009 and HM Treasury recognition, not on a single regulation with a single issuer authorisation. The substitution trap is assuming a token’s EU classification carries across. A token that is an e-money token under MiCAR is not automatically a qualifying stablecoin under the FCA regime, and it is plainly not automatically a systemic stablecoin under the Bank’s regime. Each perimeter has its own gate.

The numerical divergence is sharp on holding restrictions. MiCAR does not impose a per-coin holder cap of the kind the Bank consulted on and then dropped; instead it caps the use of significant non-euro-denominated tokens as a means of exchange by reference to transaction volume and value thresholds. The UK has now landed on an issuer-level issuance guardrail of £40 billion per coin. Those are different tools aimed at overlapping concerns, and a group operating in both jurisdictions cannot run a single backing or distribution model and assume it satisfies both. For the EU side of that comparison, our guide to MiCAR reporting obligations sets out the issuer reporting that applies to ARTs and EMTs.

Cross-border supervision is the other live front. Stablecoin arrangements rarely stay inside one jurisdiction, and supervisors have started signing cooperation arrangements to track them. Our coverage of the EBA and NYDFS stablecoin memorandum of understanding shows how cross-border stablecoin oversight is being stitched together outside the UK perimeter.

What reporting teams should be doing before the Code of Practice is final

The temptation with a draft Code is to wait. That is the wrong instinct for a systemic-track issuer, because the data architecture takes longer to build than the form-filling, and the data architecture does not depend on the final template numbers.

The work that can be done now sits in three areas. First, the reserve data model: composition by asset type, the split between Bank of England deposits and gilts, maturity of the gilt holdings, and same-day liquidity. That model has to support the 70/30 standard ceiling and the 95% step-up position for systemic-at-launch issuers and FCA-transition issuers, and it has to produce point-in-time and intraday views, not just month-end snapshots. Second, redemption telemetry: the ability to evidence that full redemption requests are processed at face value as soon as practicable and within 24 hours, including under stress, because redemption performance is exactly the metric a financial-stability supervisor will want to see. Third, the capital calculation engine for the business-risk standard, which needs a defensible estimate of the cost of executing the recovery plan and orderly wind-down plan and a clean six-months-operating-expenses figure, refreshed as the cost base changes.

What should not be done now is hard-coding return names, remittance dates or validation rules. None of those are fixed. The Code of Practice is in draft and open for feedback until 22 September 2026, the Bank intends to finalise it by the end of 2026, and the regime is built to allow operation from 2027. A reporting build that bakes in specific template identifiers today is building on sand. Map the domains, leave the form layer abstract.

For firms that already file Bank of England returns through other channels, the operational lesson from existing UK liquidity reporting is worth carrying over. Our note on recent Sterling Monetary Framework collateral eligibility changes is a reminder that the Bank revises the detail of what it will accept and how it expects it to be reported, and that firms that track those revisions early avoid the late scramble.

Frequently Asked Questions

When does the UK systemic stablecoin regime actually start applying to my firm?

The obligations attach only once HM Treasury makes a recognition order designating the stablecoin arrangement as systemic, after consulting the Bank of England and relevant regulators, including the FCA and the Payment Systems Regulator where relevant. The Bank published its policy statement and draft Code of Practice on 22 June 2026, feedback is open until 22 September 2026, the Code is intended to be finalised by the end of 2026, and regulated systemic stablecoins are expected to be able to operate from 2027. Until a recognition order exists, your stablecoin is regulated by the FCA, not the Bank.

What happened to the £20,000 individual and £10 million business holding limits?

They were proposed in the November 2025 consultation and removed in the June 2026 policy statement. The Bank replaced them with a temporary issuance guardrail set at £40 billion per systemic stablecoin. The guardrail is intended to protect access to credit while being easier to operate than wallet-level holding caps, and it is to be reviewed regularly and removed once the Bank is satisfied the credit-provision risks are addressed.

How much of the reserve can sit in gilts rather than at the Bank of England?

The policy statement allows up to 70% of backing assets in short-term UK government debt, with at least 30% in unremunerated Bank of England deposits. That is up from the 60% gilt ceiling in the consultation. Issuers recognised by HM Treasury as systemic at launch, and those transitioning to systemic status from the FCA regime, can use the step-up approach and hold up to 95% in short-term UK government debt as they scale, reducing to the standard steady-state ceiling once at appropriate scale; the detailed mechanics of moving from FCA solo regulation into joint Bank-FCA regulation will be addressed in the forthcoming Bank-FCA joint regulatory approach.

What is the redemption standard for a sterling systemic stablecoin?

The June 2026 policy statement and draft Code require redemption requests to be processed as soon as practicable and, in any event, within 24 hours of receipt of a full redemption request. The 24-hour clock starts only after the issuer has the redemption request, completed AML/KYC checks and received the coins in its wallet from the coinholder. Redemption must be at face value without undue constraint or cost; fees, if any, must be fair, transparent and proportionate and may be deducted only with the coinholder’s consent.

How does the Bank of England regime relate to the FCA’s stablecoin rules?

The FCA regulates non-systemic stablecoin issuance and cryptoasset custody as regulated FSMA activities, with its proposals in CP25/14 and CP25/15 and the wider cryptoasset regime scheduled to commence on 25 October 2027; final FCA rules are still expected through policy statements ahead of commencement. The Bank regulates stablecoins that HM Treasury recognises as systemic. Once a stablecoin is systemic, it is dual regulated: the Bank for prudential and financial-stability purposes and the FCA for conduct. Systemic status adds a supervisor rather than removing one.

Which UK law gives the Bank of England the power to do this?

The Financial Services and Markets Act 2023 expanded the Bank’s remit to cover digital settlement assets, with a DSA defined in Schedule 6 to that Act. The supervisory powers themselves sit in Part 5 of the Banking Act 2009, as amended by FSMA 2023, which lets the Bank supervise systemic DSA payment systems and service providers once HM Treasury has made a recognition order.

Do we know the exact returns, templates and deadlines yet?

No. The specific reporting templates, frequencies and remittance dates are not fixed. The draft Code contains core rules, notification and record-keeping expectations, and the Bank expects to consult in 2027 on any further updates needed for disclosures, reporting and record-keeping. The sensible approach is to build the reserve, redemption and capital data models now and leave the form layer abstract until the final reporting requirements are published.

How does the UK regime differ from MiCAR for a group operating in both?

The UK has not adopted or onshored MiCAR. The UK perimeter rests on FSMA 2023, the Banking Act 2009 and HM Treasury recognition, while the EU regulates the same instruments as e-money tokens or asset-referenced tokens under MiCAR with EBA and national supervision. A token’s EU classification does not carry across to the UK gate, and the holding and issuance controls differ, so a single backing and distribution model will not satisfy both jurisdictions.

Key Takeaways

  • The Bank of England published its policy statement and draft Code of Practice for sterling-denominated systemic stablecoins on 22 June 2026, with feedback open until 22 September 2026, finalisation intended by the end of 2026 and operation expected from 2027.
  • The individual £20,000 and business £10 million holding limits from the November 2025 consultation were dropped and replaced with a temporary issuance guardrail of £40 billion per systemic stablecoin.
  • Backing assets may now hold up to 70% in short-term UK government debt, raised from 60%, with at least 30% in unremunerated Bank of England deposits; issuers recognised as systemic at launch, and those transitioning to systemic status from the FCA regime, can use the step-up approach and hold up to 95% in short-term UK government debt as they scale, reducing to the standard steady-state ceiling once at appropriate scale, while the detailed mechanics of moving from the FCA regime into joint Bank-FCA regulation remain subject to the forthcoming Bank-FCA joint regulatory approach.
  • The legal basis is the Financial Services and Markets Act 2023, which defines digital settlement assets in Schedule 6 (introduced by section 22), and Part 5 of the Banking Act 2009 as amended by FSMA 2023, with HM Treasury making the recognition order that triggers the regime.
  • Systemic stablecoins are dual regulated by the Bank of England for prudential purposes and the FCA for conduct, with the FCA’s non-systemic regime set out in CP25/14 and CP25/15; final FCA rules remain subject to forthcoming policy statements ahead of the wider cryptoasset regime commencing 25 October 2027.
  • The redemption standard is processing as soon as practicable and within 24 hours of receipt of a full redemption request; the general business risk capital requirement is the higher of recovery and orderly wind-down cost, excluding amounts held in the wind-down reserve, or six months of operating expenses; the issuer must notify the Bank if capital falls below 110% of that minimum.
  • Detailed return names, frequencies and deadlines are not yet fixed; the draft Code contains core rules and record-keeping expectations, with the Bank expecting to consult in 2027 on further reporting updates; reporting teams should build reserve, redemption and capital data models now and leave the template layer abstract.
  • The UK has not onshored MiCAR, so EU classifications do not carry across and a single backing or distribution model will not satisfy both regimes.

Building to the regime, not the consultation

The firms that get this right will be the ones that read the policy statement as a moving target with a fixed direction. The figures the Bank settled on in June 2026, a £40 billion issuance guardrail, a 70/30 reserve split, and a 95% step-up for systemic-at-launch issuers and FCA-transition issuers reducing to the standard steady-state ceiling at scale, are the current shape, and they replaced the consultation numbers cleanly. The detailed Bank-FCA transition mechanics are still to be set out separately. The reporting detail behind them is not settled, and pretending it is helps no one. Build the reserve, redemption and capital data now, keep the template layer abstract, and watch the 22 September 2026 feedback window and the end-of-2026 finalisation for the form numbers. The recognition order, when it comes, will not wait for a firm that started late.
