The United Kingdom's Financial Conduct Authority opened applications on Wednesday for crypto businesses seeking authorization under the country's new regulatory regime, which takes effect on Oct. 25, 2027.

The move begins the formal authorization process for what will be the UK's most comprehensive crypto framework to date. The FCA finalized its rules in June, extending the regulator's oversight well beyond the anti-money laundering and financial promotion requirements that currently govern the sector. The finalized rules cover stablecoin issuance, crypto trading platforms and market abuse.

Companies intending to continue operating in the UK market should apply by the end of February 2027, according to the regulator. The FCA expects to decide on applications submitted during that window before the regime takes effect in October 2027.

"The UK's new crypto regime will give consumers greater protections and firms a clear framework to operate in," said Dominic Cashman, the FCA's director of authorization.

The opening of the application window marks a structural shift for the UK crypto industry. Firms currently registered under money laundering regulations will not automatically transition into the new regime, and the scale of the compliance lift varies sharply by business model.

A Fresh Authorization Process

Industry figures welcomed the clarity but cautioned firms against assuming their existing registrations will ease the path to full authorization.

Emma Banymandhub, CEO of The Payments Association, a payments industry trade body, urged businesses already registered under money laundering regulations (MLRs) to treat the new regime as a fresh authorization process rather than an upgrade of their current status.

"MLR registration will not carry over, and firms should be realistic about the standards they will need to meet," she said in comments shared with Cointelegraph.

Banymandhub noted that implementation would be particularly consequential for smaller and growing businesses, which face proportionally heavier compliance and operational burdens in preparing applications that meet the FCA's finalized standards.

What Changes Under the New Regime

The expansion is significant for market structure. Until now, the FCA's crypto oversight has centered on AML registration and the financial promotion rules introduced in 2023, which restricted how crypto firms can market to UK consumers. The new regime brings core market infrastructure — including trading platforms and stablecoin issuers — under prudential and conduct requirements closer to those applied in traditional financial services.

For crypto trading platforms, authorization means demonstrating operational resilience, governance and market abuse controls comparable to regulated trading venues. For stablecoin issuers, the June rules impose requirements on reserve management, redemption and disclosure.

The deadline structure gives firms roughly a year and a half from Wednesday's opening to prepare and submit applications. Firms that miss the February 2027 cutoff risk falling outside the FCA's decision window before the regime becomes binding, leaving their UK operations in legal limbo once the October 2027 start date arrives.

The FCA's authorization process will now determine which firms can access the UK market as a fully regulated jurisdiction — and which exit it.
