The UK stands on the cusp of implementing a comprehensive regulatory framework for cryptoassets, fundamentally reshaping the landscape for firms wishing to serve UK clients. The final form of The Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2025 has been laid before parliament and, together with the Financial Conduct Authority’s consultations on the new cryptoasset regime, sets out the activities within scope, the geographical reach of the regime, and the expectations for both domestic and overseas firms. As the regime nears full commencement (scheduled for 25 October 2027), cryptoasset businesses, whether based in the UK or abroad, must assess whether their operations will be captured by the new requirements and prepare for authorisation and ongoing compliance.
