Britain’s Financial Conduct Authority released final guidance on Wednesday clarifying which cryptoasset activities will require authorization under the country’s forthcoming regulatory regime. The guidance arrives as applications for authorization are set to open on September 30, 2026, with the full rules taking effect on October 25, 2027.

The move comes one day after the Home Office and HM Treasury announced a $676 million commitment over three years to strengthen efforts against money laundering, citing the role of cryptoassets, fintech and artificial intelligence in expanding the threat.

Authorization Window and Key Dates

Firms can submit applications for authorization starting September 30, 2026. Those that apply by February 28, 2027, will benefit from transitional arrangements allowing them to continue operating while the FCA reviews their submissions. Companies that miss this deadline risk restrictions after the regime begins, including limits on onboarding new customers and potential pauses in operations until approval is secured.

The new framework is based on the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026, which Parliament approved earlier this year. Existing registrations under money laundering rules will not automatically convert into full authorization under the new regime.

Activities Requiring FCA Authorization

The guidance specifies several activities that fall within the regulatory perimeter. These include issuing qualifying stablecoins, operating cryptoasset trading platforms, dealing in and arranging deals involving cryptoassets, safeguarding customer cryptoassets, and arranging staking services.

The rules apply not only to UK-based firms but also to overseas companies that deal with, arrange or safeguard cryptoassets for UK retail consumers. There is no overseas person exclusion for these activities. Limited exceptions cover firms serving only overseas institutional clients or those interacting with UK consumers solely through an already authorized UK dealer or platform.

Firms have been advised to obtain independent legal advice to determine the precise permissions they require. The FCA has indicated it will assess certain decentralized finance arrangements on a case-by-case basis where an identifiable controlling entity exists, though the precise definition of that concept remains under further development.

The regulator plans additional consultation in October on topics including qualifying stablecoins, proprietary trading, certain technology providers, decentralized protocols and financial promotions. Pre-application discussions and webinars are already available to support firms preparing submissions.

Government Allocates Funding to Combat Money Laundering

Separately, the UK government committed $676 million over three years to expand anti-money laundering and asset recovery capabilities. The funding, drawn from the economic crime levy on regulated firms, will support the hiring of 500 additional officers from police forces, the National Crime Agency and the Crown Prosecution Service.

Officials have identified money laundering as a persistent problem estimated by the National Crime Agency at more than $135 billion annually flowing through UK or British corporate structures. Cryptoassets rank among the priority areas for enforcement, alongside the broader impact of fintech and artificial intelligence.

The initiative builds on existing efforts such as Operation Destabilise, which has targeted networks converting street cash into cryptoassets. That operation has so far resulted in 119 arrests and the seizure of more than $34 million in cash and cryptoassets.

Home Secretary Shabana Mahmood stated that the focus would remain on the organizers of criminal networks rather than lower-level participants. The FCA is expected to play an expanded role in anti-money laundering oversight under the new strategy.

Until the full regime takes effect in October 2027, existing money laundering registration requirements and financial promotions rules will continue to apply. The combination of clearer authorization pathways and heightened enforcement resources forms the core of the UK’s current approach to bringing cryptoasset activities within a structured regulatory framework.
