UK FCA finalizes crypto rules: Authorization opens Sept 2026

6.6 Regulation

Sep 16, 2026

The UK FCA has finalized cryptoasset rules, effective October 2027. Firms must apply for authorization between September 2026 and February 2027. Rules cover stablecoins, trading, custody, and overseas firms serving UK clients.

The UK Financial Conduct Authority (FCA) has released final guidance clarifying the regulatory perimeter for cryptoassets. This guidance specifies which activities will require authorization under the upcoming regime, established by the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026. The new framework takes effect on October 25, 2027. Firms must apply for authorization between September 30, 2026, and February 28, 2027. Covered activities include issuing qualifying stablecoins, operating trading platforms, proprietary trading, order matching, custody, and staking. The rules apply to both UK-based and overseas firms serving UK retail customers, with no overseas person exclusion. Firms missing the February deadline will lose transitional provisions and may be restricted to servicing only existing contracts after October 2027. Existing registrations under other frameworks will not automatically convert, so firms must assess and apply for new permissions. Additionally, the UK government has committed £500 million to combat money laundering risks linked to crypto and AI technologies.
