UK FCA Just Set the Rules for Crypto in 2027

FCA Crypto Rules Put Firms on a 2026 Authorisation Clock

Applications open on September 30 and close on February 28, 2027 for firms that want to use the planned savings, or transitional, provisions. A firm that applies in that period may continue specified activities while its case is assessed, subject to the conditions. Firms that apply after the window closes may have to stop the relevant activity until the FCA authorises them.

The regulator made a point that could catch out existing businesses: registrations will not convert automatically. A firm registered under the Money Laundering Regulations, or authorised under payment-services or electronic-money rules, must still seek FCA authorisation if it carries out an in-scope cryptoasset activity.

That creates a practical deadline for the companies that already market to UK customers. The FCA says applicants must satisfy its Threshold Conditions on an ongoing basis, meaning the test reaches governance, financial resources, operational capability and suitability, rather than only a one-time filing.

The regime will also apply to overseas firms that provide cryptoasset services in or to the UK, according to the FCA’s final-policy overview. Exactly how individual international business models fall inside the perimeter will depend on the activities and facts, and the FCA has said it will publish further perimeter material in September.

Coinbase’s recent UK MiFID licence shows why the distinction matters. An investment-services licence can open a regulated lane for derivatives and equities, but it is not a substitute for the new cryptoasset permissions that will govern the broader 2027 regime.

Stablecoins, Custody and Staking Get Specific FCA Controls

For stablecoin issuers, the final rules cover backing assets, safeguarding, redemption and disclosures to holders. The FCA removed the need to estimate redemption forecasts in its backing-asset composition test, confirmed statutory trust arrangements for backing assets and allowed a backing pool to hold up to a 5% excess.

It also cut the K-SII stablecoin issuance capital coefficient to 1% from the proposed 2%. That adjustment is directed at proportionality for larger issuers, although it does not remove the requirement to keep reserve assets and redemption arrangements robust.

The rules divide the UK stablecoin market between the FCA and the Bank of England. The FCA will supervise ordinary issuers, while a payment stablecoin recognised as systemic by HM Treasury can move into joint oversight. Daily Crypto Briefs covered the Bank’s separate 40 billion pound systemic stablecoin ceiling, which applies only once a coin becomes important enough to the payments system.

Custody rules are equally detailed. The FCA will apply CASS 17 safeguards to client cryptoassets, including controls around ownership rights, records, reconciliation and private-key management. The final text uses a technology-neutral approach to keys, but it expects a custodian to show how it controls access and protects client assets.

For retail staking, providers must give disclosures, contractual terms and obtain client consent, alongside keeping records. The FCA said consent may cover ongoing staking of current and future holdings if conditions are met and clients receive an annual notification. Lending and borrowing providers must maintain enhanced disclosures, appropriateness checks, records, over-collateralisation and negative-balance protection.

Those rules put the UK closer to the post-authorisation supervision now emerging in Europe. The EU’s recent crypto custody resilience review similarly focuses on key management, transaction controls, incident response and third-party dependencies rather than treating a licence as the end of the risk assessment.

UK Exchanges Face Market-Abuse and Capital Rules in 2027

Trading platforms will be subject to admissions, disclosure and market-abuse rules. The FCA said the relative immaturity of crypto markets means residual market-abuse risk is likely to remain higher than in established markets, so large UK qualifying cryptoasset trading platforms will have specific monitoring and inside-information responsibilities.

The regulator softened some details after consultation. It removed principal dealers from pre-trade transparency requirements and said best execution requires effective overall arrangements, periodic monitoring and post-trade analysis, rather than a price check for every transaction.

Its prudential framework also separates cryptoassets that can be prudently valued and are admitted to a UK qualifying platform from those that cannot. The first category will generally face a 40% net cryptoasset-position requirement and a 40% counterparty-credit-default volatility adjustment. Assets outside that condition will be deducted from regulatory capital and receive a 100% counterparty-credit-default volatility adjustment.

Not every issue is settled. The FCA plans later consultations on DeFi guidance, firm failure and resolution, audit, financial crime, reporting and distributed-ledger technology. It says rules will apply to DeFi where an identifiable controlling entity exists, while the treatment of decentralisation will be assessed case by case.

Alternative.me showed the Crypto Fear and Greed Index at 10, or Extreme Fear, on July 10.

The next fixed date is September 30, when the authorisation gateway opens. Firms should then watch the February 28 cut-off, the FCA’s September perimeter statement and the October 2027 start date. The new rules bring much more of the UK crypto business under a single framework, but product risk and the remaining DeFi boundary will still be tested in practice.
