Companies will be required to meet financial resilience requirements, including capital and stress testing, along with new market integrity rules targeting insider trading and market manipulation. Stablecoinstokens designed to hold a fixed value, are getting their own standards that aim to “build trust in how they are used over time.”
Trading platforms will also act as gatekeepers, having to vet the token and publish the disclosure document to the central repository run by the Financial Conduct Authority (FCA) before most assets can be listed. Cryptocurrency companies will fall under the FCA’s consumer duties, and retail customers will be able to access the Financial Ombudsman service for the first time. The rules are up too Decentralized financeapplies when there is a “specified controlling entity”, with further guidelines to follow.
After consultation, the financial watchdog said it had simplified parts of the system to make it more workable, including relaxed capital requirements for stablecoin issuers and trading rules tailored to how cryptocurrency markets actually operate, which included reduction The main stablecoin’s capital factor was raised to 1% from 2%.
The framework means companies do not have to “choose between regulatory certainty and space for innovation,” David Gill, executive director of payments and digital finance at the FCA, said in a statement. He added that providers “will adhere to similar standards as other financial services providers, although we cannot regulate the risks.”
The rules stem from February legislation that brought cryptocurrencies under the FCA’s jurisdiction, one of the biggest expansions of its oversight in years. Until the system enters into force, the powers of the supervisory authority remain limited to monitoring financial promotion and anti-money laundering controls. Pre-application meetings open in July, and companies can apply for a license between September 30, 2026 and February 28, 2027, and the mandatory regime will begin on October 25, 2027.
Industry groups welcomed the clarity. CryptoUK’s Sue Carpenter said the final guidance allows the UK to “move forward with greater certainty” as a “competitive jurisdiction”, while UK Finance praised the “balanced approach that encourages innovation and protects consumers”. The FCA is also working with the Bank of England, which will oversee large “systemic” stablecoins, on a joint system.
Hannah McKean, partner at law firm Norton Rose Fulbright, described the rules as “an important step in bringing cryptocurrencies into a more established regulatory framework in the UK.” She added that the regulator aims to address “key risks that may have hindered its wider adoption”, by applying familiar financial services standards to areas including consumer protection, governance and market integrity.
The package caps a busy stretch of cryptocurrency policymaking in the UK.

For cryptocurrency companies, “the focus will now be on preparing for licensing and ensuring they have the necessary systems, controls and regulatory arrangements in place well in advance of implementation,” McCain said.
