UK unveils sweeping crypto rules for 2027

The UK FCA has finalized strict crypto regulations, including capital requirements and market abuse controls, effective October 2027. Firms must reapply for authorization under the new regime.

The UK's Financial Conduct Authority (FCA) has finalized a comprehensive regulatory framework for crypto asset firms. The new rules introduce detailed requirements on capital reserves, market abuse controls, stablecoin standards, and operational transparency. Effective from October 25, 2027, all firms operating in the UK or serving UK clients—including trading platforms, custodians, stablecoin issuers, lending, and staking providers—must seek FCA authorization between September 30, 2026, and February 28, 2027. Existing anti-money laundering registrations will not be automatically transferred. The framework sets a standardized capital requirement of 40% of a firm's net risk position for listed crypto assets and 1% for stablecoin issuers, down from the initially proposed 2%. Annual stress tests are required, and market abuse rules now cover insider trading and market manipulation. The FCA has also eased some earlier proposals, allowing matched principal and affiliate trading, and favoring disclosure and consent guidelines over blanket restrictions on retail lending and borrowing. These measures position the UK as a leader in crypto regulation, setting a high standard for global market practices.
