The UK’s Financial Conduct Authority opened applications for its new cryptoasset licensing regime on September 30, the first day of a window that runs to February 28, 2027. Exchanges, custodians, trading platforms, lenders and stablecoin issuers now fall under a single rulebook, the most sweeping overhaul of UK digital asset oversight to date.
The framework was finalized on June 29 and 30 after a long consultation. It sets standards for governance, consumer protection, custody, market integrity and operational resilience, and pulls crypto firms closer to rules already applied to banks and traditional investment firms. The full regime takes effect on October 25, 2027.
Existing anti-money laundering registrations do not transfer automatically. Firms that want to keep operating must apply for authorization under the new rules, and those that miss the window face the prospect of shutting their UK operations. That deadline pressure is the point: the FCA wants the informal AML-registration era to end on a fixed date, not drift.
| Date | Milestone |
|---|---|
| June 29-30, 2026 | FCA finalizes the cryptoasset rulebook |
| September 30, 2026 | Authorization applications open |
| February 28, 2027 | Application window closes |
| October 25, 2027 | Full regime takes effect |
Capital rules halved after pushback
The most closely watched change is the capital requirement for non-systemic stablecoin issuers, cut from 2% to 1% of issued value after industry feedback. Sterling-backed stablecoins stay under FCA supervision, while larger, systemically important stablecoins fall to the Bank of England.
Crypto firms will also face annual stress tests using internally designed models, submitted to the FCA for review. Under the CRYPTOPRU rules, stablecoin issuers must prove 1:1 backing with eligible assets and maintain real-time redemption capability on a T+1 cycle.
David Geale, the FCA’s executive director for payments and digital finance, said the UK now has a comprehensive crypto framework covering trading, custody, consumer protection and risk management. He said the package applies the same core principles used across financial services, so equivalent risks draw equivalent regulatory treatment.
The FCA’s new framework is broadly aligned with MiCA in its direction of travel. Both regimes seek to bring cryptoasset service providers, custody, trading platforms, stablecoins, market integrity and consumer protection within a clearer regulatory perimeter. – Elisenda Fabrega, general counsel at Brickken, speaking to CCN
Parallel to MiCA, not a copy
Fabrega told CCN the framework should be read as running alongside Europe’s Markets in Crypto-Assets regulation rather than diverging from it. The difference is not that the FCA regulates areas that MiCA does not, she said. The FCA framework should be understood as a parallel regime: similar in substance, but designed to give the UK its own regulatory pathway and to support its ambition to remain a competitive global hub for digital assets.
That positioning matters for firms issuing stablecoins across jurisdictions. A company operating in the four largest Western markets now faces four separate capital, reserve and redemption regimes.
| Jurisdiction | Framework | Key requirement |
|---|---|---|
| UK | FCA cryptoasset regime | 1% capital for non-systemic issuers, T+1 redemption |
| EU | MiCA | Single EU-wide license, reserve rules for e-money tokens |
| US | GENIUS Act | Treasury reserve oversight for payment stablecoins |
| Hong Kong | Stablecoins Ordinance | HKMA licensing, no yield paid on reserves |
Hong Kong’s ordinance took full effect in August 2025 and bars issuers from paying yield on reserve assets to holders, a rule the UK has not copied. The US Treasury enforces reserve oversight under the GENIUS Act. The UK just became the newest entry on that list of parallel regimes.
What happens next
For stablecoin issuers, the capital cut from 2% to 1% directly changes the economics of issuance. On a 1 billion pound float, that is 10 million pounds of capital freed up instead of 20 million, at a time when issuers are competing on fees that have already compressed. The FCA held the line on backing and redemption requirements, so the concession came on capital rather than on reserve quality.
The application window gives firms five months. Compliance teams now face the practical work of mapping custody arrangements, reserve attestations and redemption processes against the new requirements. Firms that waited for the final rulebook have their answer. The ones that prepared early get a head start on queue position, and in a licensing regime, queue position is worth real money.
The UK market itself is not small. UK crypto investors declared 1.38 billion pounds in capital gains in the most recent tax year data, and the FCA has signaled it wants the country to compete for digital assets business rather than watch it move offshore. Whether the rulebook achieves that depends on how the first wave of applications is processed.
Security teams face their own deadline work. Industry commentary ahead of the gateway opening has focused on the operational side: zero-trust API access, multi-party computation custody arrangements and stress-tested infrastructure, the pieces the FCA will actually inspect when reviewing an application. A firm with clean reserve attestations but weak operational resilience can still fail authorization.
For consumers, the practical change arrives later. Until October 2027, firms operate under the old registration while their applications sit in the queue. The consumer protection and market integrity standards bind fully only when the regime goes live. Anyone choosing a UK crypto exchange or lender in the next year is still dealing with the old rules, which is worth remembering when marketing materials start citing the new framework as if it already applied.
The FCA has not said how long individual authorizations will take to process. Comparable licensing regimes in Europe saw first-wave approvals stretch for months. Firms banking on a quick approval before the October 2027 start date have less slack than the five-month window suggests, because a rejection or a request for more information resets the clock.
