How the Bank and the FCA split systemic sterling issuers

The Bank of England and the Financial Conduct Authority (FCA) have split supervision of systemic sterling issuers so that HM Treasury recognition adds Bank prudential rules on top of the FCA regime that already covers every UK qualifying-stablecoin issuer.

The joint approach document of June 30, 2026 maps that split against the Bank’s draft Code of Practice, published with its policy statement on June 22, 2026, and against FCA Policy Statement PS26/10. Section 191 of the Banking Act 2009 is how the Bank would phase a newly recognised issuer onto stricter backing, capital and redemption standards over 12 to 36 months. Firms that HM Treasury leaves unrecognised stay on the FCA solo rulebook.

Key facts

• The joint approach is dated June 30, 2026, the draft Code June 22, 2026, and PS26/10 June 30, 2026, on the FCA’s cryptoasset regime page.
• Article 9M permission runs from October 25, 2027 under the Cryptoasset Regulations 2026. The joint paper says firms should apply by February 2027. Gateway timing is in our report on the FCA cryptoasset gateway.
• A recognised issuer keeps at least 30% of backing assets on deposit at the Bank and up to 70% in gilts of six months or less. The June 22, 2026 news release lifted the interest-bearing share from 60% to 70%.
• A £40 billion guardrail applies to each systemic coin from the recognition day, replacing the per-holder limits in the November 10, 2025 financial stability paper.
• The Code consultation closed on September 22, 2026 and the joint paper on September 30, 2026. The FCA fined CB Payments Limited £3,503,546 on July 25, 2024.

Methodology and sources

Primary UK texts are the joint approach of June 30, 2026, the Bank’s June 22, 2026 policy statement and draft Code of Practice, and FCA PS26/10, read with the November 2025 consultation, the Payments Memorandum of Understanding and the Prudential Regulation Authority’s May 2026 Dear CEO letter. The statute is the Banking Act 2009 as amended by the Financial Services and Markets Act 2023, plus the Cryptoasset Regulations 2026. The window runs from November 2025 through the joint paper, which promises a summary of responses as a later document.

Comparators are Regulation (EU) 2023/1114, the Markets in Crypto-Assets Regulation (MiCA), in force for stablecoin titles since June 30, 2024; the Guiding and Establishing National Innovation for U.S. Stablecoins Act (GENIUS Act), Public Law 119-27, signed on July 18, 2025; and the Monetary Authority of Singapore (MAS) framework of August 15, 2023. Tables C and D are the authorities’ summary, and the Code was still a draft when the joint paper appeared. Related items on this regulation desk are linked where they bear on the same gateway.

What the joint approach assigns to each authority

HM Treasury makes an issuer systemic. The Financial Services and Markets Act 2023 extended the Banking Act 2009 to payment systems that transfer digital settlement assets and to their issuers. An order can name the operator, a section 185A service provider, or a firm supplying essential services to either, after consultation with the Bank, the FCA and the Payment Systems Regulator. The test is whether deficiencies or disruption would be likely to threaten stability or confidence in the UK financial system, or to have serious consequences for business throughout the UK. Recognition at launch is available where that scale is judged likely.

A systemic sterling issuer is a UK firm issuing a qualifying stablecoin that HM Treasury has recognised under the Banking Act 2009 as a payment-system operator, a section 185A service provider, or an essential-service provider to either. From that day the Bank’s draft Code, in the joint approach of June 30, 2026, leads on backing assets, capital, safeguarding, failure arrangements and a £40 billion guardrail, while the Financial Conduct Authority keeps conduct, the Senior Managers and Certification Regime and financial crime under the Money Laundering Regulations 2017. A section 191 direction usually allows 12 to 36 months to reach at least 30% in deposits at the Bank and up to 70% in gilts of six months or less. Redemption within 24 hours applies from the recognition day, matching the end-of-day minimum in the Committee on Payments and Market Infrastructures and International Organization of Securities Commissions paper. The Part 4A decision, including a refusal, remains with the FCA.

Table C gives the FCA the lead on conduct, admissions, the Market Abuse Regime for Cryptoassets, senior managers and financial crime. Our report on CP26/38 and the Financial Crime Guide tracks that financial-crime column. Overlap covers resilience, governance, outsourcing and redemption. The Bank leads on backing assets, capital, safeguarding, failure arrangements and the guardrail. Conflicting FCA rules stay in place until a consultation that waits on the final Code.

Table D separates the solo book from the Bank book. The FCA redeems by the end of the next business day and floors core backing at 10% of the pool. The Bank requires redemption within 24 hours and a mix of at least 30% on deposit at the Bank and up to 70% in gilts of six months or less. The FCA allows overseas custodians and intra-group custody up to 20%. The Bank allows only UK custodians.

How four regimes treat a large issuer

The United Kingdom tests a large issuer by an HM Treasury judgement on stability, confidence and consequences for business, and that test can be applied at launch. Article 43 of the Markets in Crypto-Assets Regulation marks an asset-referenced token as significant when at least three of seven criteria are met, including more than 10 million holders and a reserve above €5 billion, and Article 45 then replaces the 2% own-funds rate in Article 35 with 3%. Public Law 119-27 requires one-for-one permitted reserves under Office of the Comptroller of the Currency supervision from January 18, 2027. Singapore’s August 15, 2023 label uses par redemption within five business days and base capital of S$1 million. Coin GBP and Coin UK are hypotheticals in the joint paper.

"This is a major milestone in delivering greater choice and innovation in UK payments. Innovation thrives on trust. And today we’ve set out the foundations of that trust for a new form of money - with prompt redemption, strong protections and central bank support. This is truly a world leading regime."

— Sarah Breeden, deputy governor for financial stability, Bank of England (Bank of England news release, June 22, 2026)

Where enforcement already has a number

The Code is still a draft, and the issuance permission dates from October 25, 2027. The penalty already on the book sits with the FCA, which keeps financial crime after recognition. The reference case is the Final Notice to CB Payments Limited, in the FCA press release of July 25, 2024.

CB Payments Limited, part of the Coinbase group, is an electronic-money institution. A voluntary requirement in October 2020 barred new high-risk customers while it repaired its framework. The FCA found that the firm onboarded or served 13,416 high-risk customers anyway. About 31% of them deposited around US$24.9 million, feeding cryptoasset transactions through other Coinbase entities of about US$226 million. Breaches went undiscovered for almost two years. The penalty was £3,503,546 under the Electronic Money Regulations 2011, after a 30% settlement discount.

"The money laundering risks associated with crypto are obvious and firms must take them seriously. Firms like CBPL that enable crypto trading need to have strong financial crime controls. CBPL's controls had significant weaknesses and the FCA told it so, which is why the requirements were needed."

— Therese Chambers, joint executive director of enforcement and market oversight, Financial Conduct Authority (FCA press release, July 25, 2024)

The notice predates PS26/10, and the firm issues e-money rather than a qualifying stablecoin, so the precedent sits on the conduct column rather than on backing assets. What travels into joint regulation, on Table C, is financial crime, the Senior Managers and Certification Regime and the Money Laundering Regulations. A section 191 direction can phase capital, backing assets and safeguarding, while those financial-crime duties stay in force, and the July 2024 figure is what a breached restriction has already cost a UK crypto on-ramp. Failure arrangements are marked Bank-led, with a further consultation flagged at section 2.2.7 of the June 2026 policy statement. The protection specified now is a trust over backing assets and the financial-risk reserve for coinholders, and a separate trust over wind-down reserves for an insolvency practitioner, a return of funds or a transfer of the business.

The May 2026 Dear CEO letter tells a retail issuer to use an insolvency-remote, non-deposit-taking entity with branding distinct from any deposit-taker. Inside a group the Prudential Regulation Authority already authorises, capital overlap is sorted case by case.

What joint recognition changes for firms and their advisers

A firm outside recognition lives on PS26/10: a Part 4A permission from October 25, 2027, the 10% core-backing floor, next-business-day redemption, and own funds at the higher of £350,000, three months of costs and 1% of issuance. The 30% deposit floor, the 24-hour rule and the £40 billion guardrail arrive with the order. For a broker, an exchange or a custodian, the dividing line is the cryptoasset sleeve left with the FCA, or the payments franchise that supports a Bank recommendation.

From the recognition day the firm is jointly regulated even where a direction softens the Code. In the Coin GBP illustration, 24-hour redemption, the guardrail and a financial-risk reserve apply immediately. Backing assets and the shift to UK custodians can take up to 12 months, and capital the balance of a 36-month plan. That timetable is stricter than the flexibility in our report on Circle’s European redemption terms.

A systemic-at-launch issuer follows the Bank’s onboarding approach for new financial-market infrastructures, from a 95/5 backing mix in mobilisation to the 30/70 mix at baseline. A complete Part 4A file takes up to six months.

Table B draws the FCA’s line at issuance from a UK establishment from October 25, 2027. Overseas issuance is reached through admissions, financial promotions and UK dealing, which is why front ends need FCA PS26/18. A Payment Systems Regulator designation under the Financial Services (Banking Reform) Act 2013 is separate from recognition, and the government has proposed moving those functions to the FCA. GC26/7 leaves Senior Management Arrangements, Systems and Controls (SYSC) 15A in place where a firm uses decentralised finance. The trust in our report on Client Assets Sourcebook (CASS) 7 is distinct from the backing-asset trust in PS26/10. Separate models sit in our reports on Fed Docket R-1899, the Canada Gazette and the MAS draft delisting power.

"Recently, we issued proposed rules for so-called systemic sterling stablecoins, to enable these to come into existence as a means of payment beyond the crypto world. These rules will put into effect the key principles of assured nominal value and settlement finality."

— Andrew Bailey, governor, Bank of England (Mansion House speech, July 14, 2026)

What is still open after the consultation closed

The draft Code closed on September 22, 2026 and the joint approach on September 30, 2026. Next is a summary of responses and a final Code by the end of 2026, with the FCA’s disapplication consultation waiting on that text. Certain stablecoins may settle securities in the Digital Securities Sandbox. Wider use as a settlement asset depends on amending the Central Securities Depository Regulations, and a sandbox approval stays apart from recognition.

The June 22, 2026 news release replaced per-person holding caps with a £40 billion cap on each systemic coin and raised the interest-bearing share from 60% to 70%. The 30% slice at the Bank is a cost MiCA and Public Law 119-27 spare other issuers, and the Bank’s answer is prompt redemption plus a liquidity backstop. A compliance team’s dated item is a February 2027 application, because an incomplete Part 4A file can take 12 months and recognition leaves that decision with the FCA.

TL;DR

HM Treasury recognition adds the Bank of England beside the FCA. Until the order a UK issuer is on PS26/10, with the 10% core backing floor in the joint paper of June 30, 2026. After the order the draft Code requires at least 30% of backing assets on deposit at the Bank, redemption within 24 hours and a £40 billion guardrail, phased over 12 to 36 months under section 191. The FCA keeps conduct and financial crime. The FCA fined CB Payments Limited £3,503,546 on July 25, 2024. The Code is aimed for the end of 2026, and issuance permission dates from October 25, 2027.

Frequently asked questions

Who can HM Treasury recognise as a systemic stablecoin issuer?

HM Treasury can recognise the operator of a payment system that transfers digital settlement assets, a service provider under section 185A of the Banking Act 2009, or a firm supplying essential services to either. Advice weighs volumes, substitutability, interconnectedness and the nature of use. Everyday payments count for more than cryptoasset trading at the same turnover, and recognition at launch is available where that scale is judged likely. The joint approach of June 30, 2026 keeps the Part 4A decision with the FCA, so a recognition order stands apart from authorisation.

What must a recognised sterling issuer hold as backing?

The draft Code requires at least 30% of backing assets in deposits at the Bank and up to 70% in UK government debt of six months or less. The June 22, 2026 news release lifted that interest-bearing share from 60% in the November 2025 consultation. During mobilisation a systemic-at-launch issuer may hold 95% in short gilts and 5% in unremunerated central bank deposits, then move to the 30/70 mix. The Bank also intends a gilt-backed lending facility for exceptional stress. Solo issuers stay on a core floor of 10% of the pool.

What changes for an issuer that stays non-systemic?

An unrecognised UK issuer is solo-regulated under PS26/10. From October 25, 2027 it needs a Part 4A permission to issue from a UK establishment, and firms that want that permission on the day should apply by February 2027. Before the gateway the route is Money Laundering Regulations registration. The solo book is a 10% core-backing floor, next-business-day redemption, and own funds at the higher of £350,000, three months of costs and 1% of issuance. The 30% deposit floor, the 24-hour clock and the £40 billion guardrail arrive only with recognition.

What applies on the recognition day, and what can be phased?

The Bank expects 12 to 36 months under section 191 of the Banking Act 2009. In the Coin GBP illustration, 24-hour redemption, the £40 billion guardrail and a financial-risk reserve apply on the recognition day. The settlement account, payment-system access and the move to UK custodians can take up to 12 months. Capital and wind-down reserves can take up to a further 24 months. Without a direction, the Code applies in full from the day of the order.

How does this differ from MiCA’s significant-token test?

Article 43 of Regulation (EU) 2023/1114 marks a token as significant when at least three of seven criteria are met, including more than 10 million holders or a reserve above €5 billion. Article 45 then replaces the 2% own-funds rate with 3%. The UK test is a Banking Act judgement on stability, available at launch. The add-on is a 30% deposit at the Bank and a £40 billion guardrail, rather than a one-point rise in own funds. MiCA’s stablecoin titles have applied since June 30, 2024.

When does UK issuance need an FCA permission?

From October 25, 2027, issuing a qualifying stablecoin from a UK establishment under Article 9M of the Regulated Activities Order needs a Part 4A permission. Firms that want to be authorised for that date should apply by February 2027. A complete application has a period of up to six months, and an incomplete one of up to 12 months. An issuer recognised before October 25, 2027 still needs Money Laundering Regulations registration. Recognition leaves the FCA free to refuse.
