新法規適用對象包含加密貨幣交易平台、資產託管機構、穩定幣發行商、借貸與質押服務商，以及具備可識別控製主體的部分去中心化金融（DeFi）項目。依規範，英國合格加密資產交易平台（QCATP）須對上架資產完成盡職調查、符合準入標準並完整揭露相關文件；市場濫用規範同步納入內線交易與市場操縱行為。穩定幣發行商需達成儲備資產、託管、贖回及資訊揭露各項要求，備援資產可持有最高5%超額儲備。FCA同時將穩定幣發行適用的K-SII資本係數由2%下調至1%。相關業者可於2026年9月30日至2027年2月28日間申請執照；原有反洗錢註冊資格無法自動轉換為新式執照，所有加密監管業務均須重新取得FCA授權。

The new rules apply to crypto trading venues, custodians, stablecoin issuers, lending and staking service providers, and certain DeFi projects with identifiable controlling entities. Qualified Crypto Asset Trading Platforms (QCATPs) in the UK are required to conduct due diligence on listed assets, meet admission criteria and disclose relevant documentation; market abuse provisions will cover insider dealing and market manipulation. Stablecoin issuers must comply with requirements for reserve assets, custody, redemption and disclosure, and may hold excess reserves of up to 5% for supporting assets. The FCA also cut the K‑SII capital factor for stablecoin issuance from 2% to 1%. Eligible firms may apply for licenses between 30 September 2026 and 28 February 2027. Existing anti-money laundering registrations will not automatically convert to new licenses, and all regulated crypto activities must secure fresh FCA authorization.
