This article explains a regulatory development; it does not tell you what to do with your money or which stablecoin or platform to use.
What this article covers: the framework the Bank of England and the FCA published in June 2026 for regulating sterling stablecoins, including the proposed issuance cap and reserve rules, the timeline, and what it means for people who hold or use stablecoins.
What it does not cover: how to buy stablecoins, which stablecoin to hold, or the tax treatment of crypto gains. For the wider crypto regime, see our UK crypto regulation timeline.
A stablecoin is a cryptoasset designed to hold a steady value, usually by being pegged to a currency such as the pound or the US dollar and backed by reserves. Unlike Bitcoin, whose price swings freely, a well-run stablecoin should always be worth about one unit of the currency it tracks. That makes stablecoins useful for payments and for moving money between crypto platforms, and it is also why regulators worry about them: if a widely used stablecoin lost its peg or could not honour redemptions, the disruption could spread well beyond crypto.
In June 2026 the UK set out how it intends to regulate the largest, most systemically important sterling stablecoins. The Bank of England published a policy statement and a draft Code of Practice on 22 June, and the FCA published its own stablecoin policy statement on 30 June. Together they create a two-regulator framework with a headline feature that drew attention: a temporary cap on how much of a single systemic stablecoin can be issued. This article explains what was published, what the rules require, and what they mean for ordinary users.
In short
- 22 June 2026: the Bank of England published a policy statement and draft Code of Practice for systemic sterling stablecoins.
- 30 June 2026: the FCA published its stablecoin policy statement, alongside its wider final crypto rules.
- The cap: a temporary limit of 40 billion pounds on how much of any single systemic stablecoin can be in issue.
- The backing: up to 70% of a systemic stablecoin’s reserves may be held in short-term UK government bonds (gilts), with the balance in deposits at the Bank of England.
- Timeline: the consultation on the Code of Practice closes 22 September 2026, the final Code is targeted for the end of 2026, and regulated stablecoins are expected to operate under the regime from 2027.
- For you: nothing to do today. The goal is to make sterling stablecoins safer to hold and use, with proper backing and clear redemption rights.
What was published in June 2026
Two regulators are involved because the UK has split responsibility by scale. The Bank of England takes the lead on stablecoins judged large enough to pose a risk to the wider financial system (systemic stablecoins), because that is where a failure could affect payments and financial stability nationally. The FCA regulates cryptoasset firms more broadly, including stablecoin issuers that are not systemic.
On 22 June, the Bank of England published a policy statement and a draft Code of Practice setting out how it will supervise systemic sterling-denominated stablecoins. On 30 June, the FCA published its own stablecoin policy statement as part of the same wave that delivered its final crypto authorisation rules. The result is a joined-up framework: the FCA authorises and supervises stablecoin issuers as regulated crypto firms, and the Bank of England applies additional, tougher requirements to any that become systemic.
The issuance cap and the reserve rules
The most striking feature is the temporary issuance cap. Under the Bank of England’s approach, no single systemic stablecoin may have more than 40 billion pounds in issue while the cap is in place. The Bank has framed this as a transitional measure: a way to let a genuinely large sterling stablecoin grow without allowing it to reach a scale that could destabilise the financial system before the regime and the market have matured. The cap is expected to be reviewed and potentially lifted as confidence in the framework builds.
Just as important is what must sit behind the coin. A systemic stablecoin’s reserves (the assets that make it redeemable at face value) are subject to strict composition rules. Up to 70% may be held in short-term UK government bonds, and the remainder is to be held as deposits at the Bank of England itself. The logic is safety and liquidity: short-dated gilts and central-bank deposits are about as low-risk and as readily convertible to cash as UK assets get. That backing is what should allow the issuer to meet redemptions in a stress, so that holders can reliably swap their stablecoin back for pounds.
This is a deliberately conservative model. It rules out the kind of thinly backed or opaquely backed stablecoins that have caused problems elsewhere, where the reserves turned out to be riskier or less liquid than holders assumed.
How this fits the wider UK crypto regime
The stablecoin framework does not stand alone. It sits within the broader crypto regime the FCA finalised at the end of June 2026, under which crypto firms serving UK consumers must be FCA-authorised, with the full regime going live on 25 October 2027. Stablecoin issuers are one category of firm within that regime; systemic ones simply face an additional layer of Bank of England supervision on top.
If you want the full picture of how UK crypto regulation is being built, including the authorisation gateway and what changes for platforms, our UK crypto regulation timeline covers it in detail. This article focuses specifically on the stablecoin layer.
What it means for you
What you gain
- Proper backing. A regulated systemic sterling stablecoin must hold high-quality, liquid reserves in a defined mix of short-term gilts and Bank of England deposits. You are no longer relying on an issuer’s word about what stands behind the coin.
- Redemption you can rely on. The framework is built around the promise that you can redeem the stablecoin for pounds at face value. The reserve rules exist precisely so the issuer can honour that in a stress.
- Regulatory oversight. Systemic stablecoins get Bank of England supervision, and stablecoin issuers generally fall under FCA authorisation. That is a step change from the era when stablecoin issuers were largely outside UK financial regulation.
What to keep in mind
- No FSCS cover for cryptoassets. As with crypto generally, the Financial Services Compensation Scheme does not protect stablecoin holdings the way it protects bank deposits up to 85,000 pounds. The safeguards here come from reserve backing and regulation, not from a compensation scheme.
- Non-sterling and foreign stablecoins differ. This framework is about systemic sterling stablecoins. Dollar-pegged stablecoins and coins issued outside the UK operate under different rules (see the US comparison below), and the protections are not automatically the same.
- The rules are not fully live yet. The Code of Practice is still in consultation, and the regime is expected to apply from 2027. The direction is set, but the detailed rulebook is still being finalised.
How the UK compares to the US
The UK is not the only one moving. In the United States, the GENIUS Act created a federal framework for dollar stablecoins, and in mid-2026 six US agencies are racing to finalise the implementing rules by an 18 July deadline. The US model shares the core idea of full reserve backing, but the details differ, including on deposit-insurance treatment and the division of responsibility between agencies. If you hold dollar stablecoins as well as sterling ones, our US stablecoin and GENIUS Act explainer covers the American side.
FAQ
What is a systemic stablecoin?
It is a stablecoin judged large or widely used enough that its failure could affect the wider financial system, particularly payments. The Bank of England takes the lead on supervising these, applying tougher requirements than apply to smaller stablecoins, which are regulated by the FCA as ordinary crypto firms.
Why is there a 40 billion pound cap?
The Bank of England has set a temporary limit on how much of any single systemic stablecoin can be in issue, to prevent one coin from reaching a destabilising scale before the regime and the market are mature. It is framed as transitional and is expected to be reviewed as confidence in the framework grows.
What backs a regulated sterling stablecoin?
Its reserves. Under the framework, up to 70% of a systemic stablecoin’s reserves may be held in short-term UK government bonds (gilts), with the rest held as deposits at the Bank of England. Both are very low-risk and highly liquid, which is what should let the issuer meet redemptions reliably.
Is my stablecoin covered by the FSCS?
No. The Financial Services Compensation Scheme protects bank deposits and certain investments, but not cryptoassets, and stablecoins are cryptoassets. The protection in this framework comes from reserve backing and regulatory supervision, not from a compensation scheme. If an issuer failed, you would rely on the reserves and the wind-down arrangements, not on FSCS compensation.
Do I need to do anything now?
No. The rules are still being finalised and are expected to apply from 2027. There is nothing you need to do today. It is simply useful to know that the UK is building a proper regulatory backstop for sterling stablecoins, and to understand that the protections apply to regulated sterling coins rather than to every stablecoin in existence.
Savvy Investor’s take
This is a cautious, stability-first framework, and that is the right instinct for stablecoins. The whole point of a stablecoin is that it should be boringly reliable, and the surest way to make it reliable is to insist on high-quality reserves and clear redemption rights. Requiring backing in short-term gilts and Bank of England deposits, and capping the scale of any single systemic coin for now, is the regulator choosing safety over speed. Given the history of stablecoins that turned out to be less solid than they looked, that is a reasonable trade.
The gap that remains is the same one that runs through all of crypto: there is no FSCS safety net. Regulation here reduces the chance of a sterling stablecoin failing and improves your odds of redeeming it if things get rough, but it does not guarantee you will be made whole. For most users the practical takeaway is simple. A regulated sterling stablecoin, properly backed and supervised, is a meaningfully safer thing to hold than an unregulated one, but it is still a cryptoasset, not a bank deposit.
