The UK Financial Conduct Authority has issued final guidance spelling out which crypto businesses will need authorization under the country’s incoming crypto regime, with the full rules due to take effect on October 25, 2027. The move gives firms a clearer timetable and defines the activities that will fall inside the framework.

The guidance covers stablecoin issuance, crypto trading platforms, dealing and arranging transactions, custody, and staking. It also makes clear that the regime will reach overseas firms serving UK customers as well as traditional financial companies expanding into crypto.

Application window and transition timeline

The FCA said applications for authorization will open on September 30, 2026. A transition window will then run until February 28, 2027, giving firms a set period to prepare and apply before the new framework is fully in force later that year.

One important point in the guidance is that existing crypto registrations will not automatically convert into authorization under the new regime. Firms already registered will still need to go through the new process if their activities fall within the scope of the rules.

What the new regime will cover

The finalized guidance is intended to remove uncertainty over which types of crypto activity will become regulated. Among the areas named by the FCA are stablecoin issuance, operation of trading platforms, dealing and arranging transactions, custody services, and staking.

The scope is not limited to specialist crypto companies. Overseas businesses offering services to customers in the UK are included, and so are established financial firms that decide to enter the crypto market.

Banking access may remain a separate problem

The clearer rulebook does not resolve a practical problem that has affected parts of the sector: access to banking rails. UK banks already block or limit some transfers linked to crypto platforms, and the FCA is not expected to force lenders to lift those restrictions when the authorization regime starts.

That leaves banks free to set their own risk appetite. In practice, a crypto business could secure FCA authorization and still face difficulties if a bank decides to restrict payments or transfers connected to the firm.

Political pressure is building

The banking issue is also drawing attention in Parliament. Amendments have been introduced that would require the Treasury to develop a national digital-assets strategy.

According to the measure, that strategy would need to address crypto, stablecoins, tokenization, and access to banking and payment services. The bill has moved on to the House of Commons, but it has not yet become law.

What comes next

For now, the FCA’s final guidance answers a central regulatory question by setting out when authorization begins and which businesses will be covered. The next confirmed step is the opening of applications on September 30, 2026, ahead of the October 25, 2027 start date for the full regime.

Whether authorized firms will also gain more reliable access to banking remains unresolved. That question appears likely to depend not on the FCA guidance alone, but on future decisions by banks and on whether Parliament turns its proposed digital-assets strategy into law.
