The UK's Financial Conduct Authority (FCA) will open a cryptocurrency license application window in September 2026, as part of a new regulatory framework for crypto-asset service providers (CASPs). The new regime, set to be implemented on October 25, 2027, requires all companies offering regulated crypto services in the UK to obtain authorization under the Financial Services and Markets Act (FSMA). The FCA will provide a limited application period, expected to last at least 28 days, for CASPs to apply for authorization. Companies already registered under existing regulations must amend their permissions, while those relying on third-party approvals for financial promotions must secure direct FCA authorization. Transitional provisions will allow companies to continue operations during the assessment period, but those missing the application window may face restrictions on launching new products.
