UK Crypto Regulation Moves Forward: Lending, Staking & DeFi - Key Takeaways from FCA CP25/40
The close of 2025 highlighted the continuing momentum for the digital asset industry, with regulatory developments accelerating rather than slowing. In December, the UK Government and the Financial Conduct Authority (FCA) released a series of draft instruments and consultation papers that are poised to play a significant role in shaping the sector’s future. On 15 December 2025, HM Treasury (HMT) published a revised draft of The Financial Services and Markets Act 2000 (Cryptoassets) Order 2025. This was followed on 16 December 2025 by the FCA’s publication of three consultation papers addressing core elements of the forthcoming cryptoasset regulatory framework: (1) CP25/40 Regulating Cryptoasset Activities, (2) CP25/41 Regulating Cryptoassets: Admissions & Disclosures and Market Abuse Regime for Cryptoassets, and (3) CP25/42 A Prudential Regime for Cryptoasset Firms. Momentum continued into the new year. On 8 January 2026, the FCA provided further detail on its proposed “gateway” the application process through which firms will seek authorisation to carry on newly regulated cryptoasset activities under the UK’s forthcoming regime.

A tax authority is a government body or agency responsible for collecting taxes, administering tax laws, and enforcing tax compliance. In the United States, the Internal Revenue Service (IRS) is the federal tax authority. Most states, territories, and local jurisdictions also have tax authorities to ensure compliance with applicable state and local laws and regulations.

What Is the Securities Exchange Act of 1934?
The Securities Exchange Act of 1934 (as amended, the “Exchange Act”) established the Securities and Exchange Commission (the SEC) and gave it the power to oversee the securities industry. Through the Exchange Act, the SEC gained the authority to register, regulate, and oversee brokerage firms, transfer agents, and clearing agencies. The Commission also has authority over the U.S. securities self-regulatory organizations (SROs), including: The New York Stock Exchange, NASDAQ Stock Market, Chicago Board of Options, and the Financial Industry Regulatory Authority. SROs must have guidelines in place to make sure investors are protected.
