UK Stablecoin Rules: PS26/10 and the 2026 Gateway
The UK regulates stablecoin issuance through SI 2026/102 and FCA final rules in PS26/10. Issuers of non-systemic UK-issued qualifying stablecoins face backing-asset, redemption, and safeguarding duties. The application gateway opened on 30 September 2026 and closes on 28 February 2027, with full commencement on 25 October 2027.
The two layers, statute and rules
British stablecoin regulation arrives in two layers. Readers who conflate them misdate the regime. The statutory layer is SI 2026/102, made 4 February 2026. It designates issuing qualifying stablecoins as a regulated activity. It sets its own commencement schedule [1]. The rules layer is the Financial Conduct Authority’s PS26/10, a June 2026 policy statement [2]. It carries the final rules for the issuers that activity covers.
The statutory instrument’s timing works in two stages. The full commencement day is 25 October 2027. Before that, a shorter clock started 21 days after the instrument was made [1]. That early clock brings into force the FCA’s preparatory powers. Rules. Guidance. The permission process itself [1]. The two-stage design explains a lot. Final rules can exist in 2026. The full regime still starts in 2027. Both dates are verbatim from the instrument.
What the FCA’s final rules cover
PS26/10 sets final rules for non-systemic UK-issued qualifying stablecoins [2]. The coverage list is explicit. Issuance. Backing assets. Redemption. Safeguarding. Disclosures [2]. The statement’s provenance is part of its weight. It followed two consultations. It drew on a sandbox cohort of four issuers. It drew on the FSRC stablecoin report.
The backing-asset rules name the categories. Core backing assets are short-term deposits and short-term government debt [2]. Five percent of the pool must sit in on-demand bank deposits, under the on-demand deposit requirement [2]. Longer-dated government debt and certain money-market instruments are available too. Those count as expanded backing assets, with FCA notification and conditions [2].
Backing must be complete from the first moment a coin exists. Issuers must fully back all UK-issued qualifying stablecoins from the point of minting [2]. That includes coins the issuer holds itself [2]. And the requirement is checked on a cadence. The composition is calculated on every redemption day [2]. The calculation is the higher of two figures. Five percent of the backing asset pool. Or the highest daily redemption percentage in the past 180 redemption days [2]. On-demand deposits cannot double-count toward it [2].
Redemption, at T+1
The redemption rule is specific. Pay out by the end of the next business day. T+1 [2]. The final rules amended the trigger in a way readers should know. The clock now starts when the issuer receives the stablecoin in its wallet [2]. Not when the full request paperwork arrives. And the anti-money-laundering checks must complete before the clock starts [2]. Two timelines run here. The consumer-facing one and the compliance one. The document says so plainly.
The own-funds floor, and where it lives
One number circulated early in the UK process. A floor on the own funds an issuer must hold. The research behind this page resolved where that number lives. The floor is not in PS26/10. It is in PS26/12, the prudential stream statement, paragraph 3.3 [3]. The figure is 350,000 pounds for firms issuing qualifying stablecoins [3]. It proceeded as consulted on. A firm’s minimum capital is the highest of its own-funds and factor requirements [3].
The correction is worth stating as a method. A number can be true and still be misattributed. Citing the right document is not pedantry. It is the difference between a claim a reader can verify and one a reader must take on trust.
The systemic tier, and two regulators
Not every issuer stays with the FCA alone. Under the Banking Act 2009, the Treasury recognizes UK systemic stablecoin issuers [2]. Before doing so it must consult. The FCA. The Bank of England. The Payment Systems Regulator. The Prudential Regulation Authority where relevant [2]. A designated systemic issuer moves from solo FCA regulation to joint regulation by the FCA and the Bank [5].
The Bank’s systemic tier carries its own numbers. Backing assets move to a maximum of 70 percent UK sovereign debt. Remaining maturity under six months. A minimum of 30 percent central bank deposits [2]. Per-coin issuance guardrails of 40 billion pounds apply, alongside capital requirements. Redemption moves to same-day, T+0 [2]. The two tiers are calibrated differently on purpose. Scale changes the rulebook.
The gateway window
The permission process has a calendar. The application window opens 30 September 2026. It closes 28 February 2027 [4]. At the research read, 11 September 2026, that opening was weeks away. Firms relying on transitional savings provisions are told to apply early. The window governs entry to the regime. Not the regime’s full start. That remains the October 2027 commencement day [1].
Where this page sits
The regulation hub frames the full jurisdiction set. The GENIUS Act page holds the American statute. The MiCA page holds the European framework in force. The instruments are introduced at stablecoins. The monthly reserve disclosures the rules will require are the document family the attestations page teaches readers to read.
