The Bank of England is weighing a shift in its planned stablecoin rulebook, opening the door to issuer-level limits on total stablecoin supply rather than strict caps on how much individual consumers and businesses can hold, after sustained pushback from the digital-assets and payments industry.

The reconsideration, outlined by Deputy Governor Sarah Breeden at City Week 2026 in London on May 19, is an important regulatory signal for fintech firms, banks, wallet providers and corporate payment users preparing for the UK’s future digital-money framework. The Bank has been designing rules for “systemic” sterling-denominated stablecoins, meaning tokens that could become widely used for payments and therefore pose risks to financial stability if they fail, lose value, or trigger rapid shifts out of bank deposits.

Breeden said the Bank would publish draft rules for systemic stablecoins next month and aims to finalize them by the end of the year. That timetable places the UK’s framework in a critical phase as global regulators compete to define the guardrails for digital payment instruments that sit between conventional banking, crypto markets and tokenized financial infrastructure.

The previously proposed regime included temporary limits of 20,000 pounds for individuals and 10 million pounds for businesses holding systemic sterling stablecoins used for everyday payments. Those caps were intended to reduce the risk that consumers and companies could move large amounts of money from bank deposits into privately issued tokens in a short period, potentially constraining banks’ ability to lend to households and businesses.

Industry groups argued that the limits would be difficult to administer, particularly across multiple wallets, intermediaries and use cases. They also warned that caps could blunt the usefulness of stablecoins for high-value corporate payments, settlement flows and programmable transactions. For fintech firms, a per-holder cap could require costly monitoring infrastructure and coordination across platforms, potentially weakening the business case for UK-issued stablecoins before the market has had time to develop.

The alternative now under consideration would place temporary guardrails on the total amount of a particular stablecoin that could be issued. Such a mechanism could allow larger individual transactions and corporate use cases while still giving regulators a way to manage aggregate exposure to a coin that grows rapidly. Breeden said such an approach could achieve the same aim at lower cost to the sector and allow a broader range of high-value payment applications.

The distinction matters for the structure of the UK’s fintech market. Holding limits act at the user level, constraining the amount any single person or business can own. Issuance guardrails act at the coin or issuer level, limiting the total stock of a stablecoin in circulation. A user-level system may directly reduce concentration and sudden flows by individual customers, but it can impose heavy compliance obligations on payment firms. An issuer-level system may be simpler to implement and more compatible with wholesale and corporate payments, but it requires regulators to determine how aggregate caps should be calibrated, reviewed and adjusted as adoption changes.

The Bank’s stated concern remains financial stability. Stablecoins are designed to maintain a stable value against a fiat currency, commonly through reserves of cash, central-bank deposits, government debt or similar assets. If a sterling stablecoin became widely used for payments, a loss of confidence could create redemption pressure, while rapid migration from bank deposits into stablecoins could alter the funding base of commercial banks. The central bank has emphasized that innovation in payments should not come at the expense of the singleness of money, confidence in redemption, or the availability of credit in the real economy.

The UK approach also reflects a broader policy balancing act. The government has promoted the UK as a potential hub for digital assets, tokenization and financial-market innovation, while regulators have moved cautiously after the failures and volatility that marked earlier phases of the crypto cycle. Stablecoins occupy a particularly sensitive position because they are used heavily in crypto trading but are also being promoted as potential payment instruments for mainstream commerce, cross-border transfers and tokenized securities settlement.

For banks, the debate is closely tied to deposit competition and the future of money. If consumers and businesses can hold large amounts of money-like tokens issued outside the deposit system, commercial banks may face new funding pressures. If banks themselves issue tokenized deposits or stablecoins through separate structures, they could participate in the new market while maintaining a clearer link to regulated banking. The Bank of England has indicated that traditional banking groups could issue stablecoins, but through structures that are separate from deposit-taking entities and insolvency-remote, with branding clear enough to avoid confusing stablecoins with insured bank deposits.

For fintech companies, the potential retreat from rigid holding caps could improve the commercial outlook for UK stablecoin products. Payment firms have argued that stablecoins could lower transaction costs, speed settlement, enable programmable payments and support cross-border use cases that existing banking rails do not handle efficiently. Corporate treasurers and merchants may be more likely to experiment with sterling stablecoins if rules permit larger balances or high-value transfers, subject to broader safeguards.

The upcoming draft rules will also matter for wallet providers and exchanges that would need to operationalize compliance. A user-level cap could require platforms to monitor customer balances across affiliated accounts and potentially coordinate with other intermediaries, raising privacy, data-sharing and liability questions. An issuance cap could shift the burden toward issuers and supervisors, although distributors would still need to manage know-your-customer, anti-money-laundering and redemption controls under the broader regulatory perimeter.

The Bank’s stablecoin work sits alongside a wider modernization push in UK payments. The central bank has separately set out plans to extend operating hours for the UK’s Real-Time Gross Settlement system and CHAPS, with changes intended to move the country toward near-continuous settlement. Those infrastructure upgrades are relevant to stablecoins and tokenized deposits because private digital-money systems will need to interact with central-bank money, commercial-bank money and wholesale settlement infrastructure if they are to move beyond pilots.

The broader vision set out by Breeden is a “multi-money” retail payments system in which traditional bank deposits, tokenized bank deposits, regulated stablecoins and potentially a retail central bank digital currency could coexist. That framework is intended to support competition and innovation while keeping the monetary system anchored in robust forms of money. For the Bank, the challenge is to allow new payment instruments to develop without allowing the risks of privately issued money to re-emerge in a digital form.

The policy shift also comes as international regulatory comparisons become more important. The European Union has implemented a comprehensive crypto-asset framework that includes stablecoin provisions, while the United States has been advancing federal stablecoin legislation and rules. The UK’s competitiveness as a digital-finance jurisdiction may depend partly on whether its regime is viewed as stringent but workable. Industry criticism of the Bank’s earlier proposals centered on the idea that the UK would be stricter than peer markets, potentially pushing issuance and payment innovation offshore.

At the same time, the Bank has little incentive to adopt a light-touch approach for systemic payment instruments. Once a stablecoin becomes embedded in commerce, corporate payments or financial-market settlement, a failure could have effects beyond crypto investors. A token that promises one-to-one convertibility into sterling must be backed by assets that remain liquid under stress, with clear redemption rights and operational resilience. The central bank’s insistence on temporary constraints reflects concern about the speed with which digital products can scale when network effects take hold.

The Bank’s 2025 consultation proposed that systemic stablecoin issuers hold a portion of backing assets as deposits at the Bank of England and a portion in short-term sterling-denominated UK government debt. That design aimed to ensure high-quality backing while allowing issuers to earn some return on reserves. Industry participants criticized elements of the reserve model as potentially costly, particularly if a large share of assets must be held in unremunerated central-bank deposits. Breeden previously said the Bank was open to revising proposals if alternative approaches could meet the same financial-stability objectives.

The May 19 remarks suggest industry engagement has produced at least one possible alternative on holding limits. A total-issuance guardrail could be reviewed regularly, giving the Bank a mechanism to loosen constraints if evidence shows stablecoins are not destabilizing bank funding or credit supply. It could also be tightened if adoption accelerates faster than expected or if redemption risks become more material. The effectiveness of such a mechanism would depend heavily on transparency around circulating supply, reserve composition, redemption flows and issuer governance.

For market participants, the next key milestone is the publication of draft rules in June. Those rules are expected to clarify the Bank’s preferred approach to holding limits or supply guardrails, reserve requirements, issuer structure, supervision and coordination with the Financial Conduct Authority. The FCA is expected to oversee conduct and non-systemic stablecoin activity, while the Bank would supervise systemic arrangements that could affect financial stability. HM Treasury’s role in recognizing systemic payment systems and service providers remains central to the perimeter.

The rule design will influence which business models are viable in the UK. A strict holding-limit framework would likely favor smaller payment use cases and limit corporate adoption. A guardrail framework could support larger flows but may constrain issuers at the aggregate level until supervisors are comfortable with market depth and risk controls. A reserve framework that is too costly could deter issuance, while one viewed as too permissive could undermine confidence in redemption and increase systemic risk.

The Bank’s evolving position does not amount to deregulation. Rather, it reflects an attempt to find a supervisory tool that matches the risk more efficiently. The central bank still wants stablecoins used as money for real-world payments to be robust, redeemable and subject to strong oversight. What is changing is the possible mechanism for controlling early-stage adoption while the market remains uncertain.

That uncertainty is substantial. Sterling stablecoins remain a small part of the global stablecoin market, which is dominated by dollar-linked tokens used in crypto trading. It is unclear whether UK consumers will adopt stablecoins for everyday purchases, whether merchants will see enough savings to support acceptance, or whether tokenized commercial-bank deposits will prove more attractive for mainstream payments. Corporate and wholesale use cases may develop faster than retail ones, particularly where programmable settlement or cross-border payment efficiency provides a clearer economic benefit.

The final rules will therefore need to work for a market that could remain niche, grow slowly, or scale rapidly if a major platform, bank or payment provider launches a compelling product. That is why temporary and adjustable constraints are becoming a central part of the policy debate. A framework that is too restrictive may prevent useful experimentation; a framework that is too loose may allow risks to build before supervisors can respond.

For the UK fintech sector, the Bank’s willingness to consider alternatives is likely to be read as a constructive signal. It suggests regulators are not abandoning financial-stability concerns but are prepared to adapt the tools used to address them. The June draft rules will show whether that flexibility translates into a regime capable of attracting stablecoin and tokenized-payment activity while maintaining the standards expected of instruments used as money.
