UK Stablecoin Rules: Why 1% Capital Does Not Mean 1% Backing
What the reported reduction from a 2% to 1% issuer-capital requirement means, what it does not mean, and why the FCA and Bank of England frameworks must be read separately.
The reported 2% to 1% change concerns capital held by a regulated issuer to absorb business losses. It is not a rule allowing a stablecoin to keep only one pound of backing assets for every one hundred pounds of tokens.
The reported coefficient belongs to the FCA issuer regime for issuing qualifying stablecoins in the UK and was described by Reuters as governing sterling-denominated stablecoin issuers. It is not a worldwide capital rule for every stablecoin already circulating in the UK.
Backing assets, liquidity, redemption arrangements, and issuer capital solve different problems. The UK is also building two connected but distinct regimes: the FCA framework for UK-issued qualifying stablecoins and other regulated cryptoasset activities, and a Bank of England framework for sterling-denominated stablecoins that become systemic payment systems.
On June 30, 2026, Reuters reported that the Financial Conduct Authority had reduced a key variable capital requirement for stablecoin issuers from 2% of the value of issued stablecoins to 1% after industry feedback. The broader UK cryptoasset regime starts on October 25, 2027.
| Headline number | What it refers to | What it does not establish |
|---|---|---|
| 2% | The earlier proposed level for a variable issuer-capital component described in the FCA prudential consultation process. | It was not the proposed backing ratio for tokens. |
| 1% | The lower final level reported after the FCA considered industry evidence and competitiveness concerns. | It does not mean the issuer may leave 99% of token liabilities unbacked. |
| October 25, 2027 | The start of the broader UK cryptoasset regulatory regime. | It does not mean every existing stablecoin becomes approved on that date. |
The final FCA policy statements and Handbook text are the controlling technical sources. This guide therefore treats the 1% figure as a reported final policy outcome and avoids converting it into a complete capital calculation for any individual firm until the relevant final text is directly verified.
| Layer | Purpose | Simple question |
|---|---|---|
| Backing assets | Support the value of outstanding tokens and the issuer's ability to return value to holders. | What assets stand behind the tokens? |
| Issuer capital | Absorb operating losses, legal costs, technology failures, compliance costs, and other business risks borne by the issuer. | Can the company survive losses without immediately failing? |
| Liquidity | Ensure assets can be converted into cash quickly enough to meet redemptions. | Can holders be paid on time during stress? |
| Safeguarding and segregation | Separate customer or backing assets from the issuer's ordinary estate and records. | Who owns the assets, where are they held, and what happens in insolvency? |
| Redemption rules | Define who may redeem, the timing, fees, minimums, suspension rights, and settlement route. | Can a holder actually turn the token back into money? |
A stablecoin can have apparently sufficient backing while the issuer itself has weak operational capital. It can also have strong corporate capital but poor backing, slow redemption, or illiquid reserves. No single percentage answers every risk question.
Assume an in-scope issuer has £100 million of stablecoins outstanding. In a deliberately simplified illustration, a 2% variable capital component would equal £2 million, while a 1% component would equal £1 million.
| Item | Simplified amount | Role |
|---|---|---|
| Outstanding stablecoins | £100 million | Token liabilities or claims in circulation. |
| Backing assets | Determined under the stablecoin backing and safeguarding rules | Assets intended to support redemption and value stability. |
| Variable issuer capital at 2% | £2 million | Additional loss-absorbing company resources under the earlier proposal. |
| Variable issuer capital at 1% | £1 million | Lower loss-absorbing company resources under the reported final adjustment. |
This example is not a complete FCA capital calculation. Fixed overhead requirements, other risk charges, group structure, permissions, deductions, and detailed Handbook rules may change the actual requirement for a firm.
The policy problem is a trade-off. Higher capital can make issuers more resilient, but it also ties up more shareholder funding and can make a low-margin sterling stablecoin business difficult to operate in the UK.
| Reason for a higher level | Reason for a lower level |
|---|---|
| More loss absorption if the issuer suffers operational, legal, governance, or technology failures. | Lower entry and scaling costs for UK issuers. |
| A larger buffer before losses reach the backing or disrupt redemption operations. | Less incentive for firms to issue elsewhere and avoid the UK market. |
| Greater resilience where the issuer depends on third parties, custodians, banks, or technology providers. | Closer alignment with evidence submitted by firms about viable business models. |
Reducing one requirement does not remove the wider framework. In-scope firms still face authorization, governance, conduct, safeguarding, disclosure, prudential, operational, and financial-crime obligations.
| Regime | Main target | What to watch |
|---|---|---|
| FCA | Issuing qualifying stablecoins in the United Kingdom and related non-systemic regulated cryptoasset activities. | Issuer authorization, backing and safeguarding, redemption, disclosure, conduct, prudential capital, and service-provider rules. |
| Bank of England | Sterling-denominated stablecoins recognized as systemic payment systems. | System-wide resilience, central-bank deposits, permitted short-term UK government debt, issuance guardrails, liquidity support, and prompt redemption. |
| HM Treasury | Legislation and recognition decisions that define the perimeter and identify systemic payment systems. | Which activities are regulated and when a stablecoin moves into the systemic framework. |
The Bank of England stated on June 22, 2026 that its systemic framework would allow up to 70% of backing assets in short-term UK government debt, with the remainder in unremunerated central-bank deposits. It replaced proposed temporary individual holding limits with an initial £40 billion issuance guardrail for each systemic stablecoin.
The Bank also made clear that its regime does not cover non-systemic stablecoins used mainly for cryptoasset trading. Those uses remain outside the Bank's systemic-payment regime and are addressed through the FCA and wider UK regulatory perimeter.
| Date | What it means |
|---|---|
| 2025-05-28 | The FCA published consultations on stablecoin issuance, custody, and prudential requirements. |
| 2026-02-04 | The Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 were made. |
| 2026-06-22 | The Bank of England published its systemic-stablecoin policy statement and draft Code of Practice. |
| 2026-06-30 | The FCA's final package was reported, including the reduction of the key stablecoin issuer-capital coefficient from 2% to 1%. |
| 2026-09-22 | Feedback closes on the Bank of England draft rules. |
| 2026-09-30 | The FCA application period opens for firms preparing for the new cryptoasset regime. |
| 2027-02-28 | The FCA application period closes. |
| 2027-10-25 | The new UK cryptoasset regulatory regime starts. |
| No immediate change to token balances | The announcement does not alter balances, contracts, or redemption rights by itself. |
|---|---|
| No universal approval | USDT, USDC, PYUSD, RLUSD, DAI, and other assets do not become approved UK stablecoins merely because the framework is finalized. |
| No global 1% rule | The reported FCA adjustment concerns its issuer regime for sterling-denominated stablecoins. Global circulation or availability through a UK service does not by itself impose that issuer coefficient on every dollar stablecoin. |
| Product and entity structure matter | A global brand may use a different legal issuer, token, or distribution arrangement for a UK-issued product. |
| Systemic status is separate | A widely used sterling payment stablecoin may later move into the Bank of England framework after recognition by HM Treasury. |
When an issuer says that a token is “UK compliant,” verify each layer rather than relying on the slogan.
| Claim to verify | Evidence to look for |
|---|---|
| Authorized issuer | FCA register entry, permissions, legal entity, and effective date. |
| Qualifying stablecoin | Token identity, reference currency, issuance entity, place of issuance, and current product documentation. |
| Backing | Eligible asset policy, custody structure, segregation, reporting period, and assurance source. |
| Redemption | Eligible customers, minimums, fees, timing, settlement currency, and suspension terms. |
| Capital | The applicable FCA formula, fixed and variable components, deductions, and consolidated treatment. |
| Systemic status | HM Treasury recognition and the applicable Bank of England rules. |
| Status | What can safely be said |
|---|---|
| Confirmed in official material | The regime starts on October 25, 2027; the FCA application window runs from September 30, 2026 to February 28, 2027; and the Bank has published a separate systemic-stablecoin framework with a 70% short-term government-debt limit and an initial £40 billion issuance guardrail. |
| Reported final FCA outcome | Reuters reported that the key variable capital requirement for issuers governed by the FCA's sterling-stablecoin issuer rules was reduced from 2% to 1% after consultation feedback. |
| Still requires technical verification | The controlling final FCA rule references, the complete firm-level calculation, the interaction with other capital requirements, and the authorization status of any named future stablecoin product. |
