FCA Publishes Crypto Perimeter Guidance for 2027 Regime

Britain's Financial Conduct Authority on Sept. 16, 2026 published final guidance explaining which cryptoasset activities will need its authorisation, including when an offshore platform serving British consumers falls inside the incoming regime. The policy statement, numbered PS26/18, arrives two weeks before the authorisation application window opens on Sept. 30.

The guidance interprets the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026, which bring activities such as issuing qualifying stablecoins, operating a cryptoasset trading platform, dealing and arranging deals, safeguarding cryptoassets and arranging staking into the regulator's perimeter from Oct. 25, 2027. Securities.io wrote on Sept. 16 that anyone carrying on those activities by way of business in the UK will need to apply for authorisation unless an exemption applies or transitional provisions cover them.

The FCA addressed the document to firms already carrying out or planning regulated cryptoasset activities, authorised firms that may need extra permissions, businesses registered under the money-laundering regulations, electronic money and payment firms, traditional finance firms exploring crypto, and overseas firms serving UK consumers. Firms must read the guidance and work out whether they need authorisation or a variation of permission, the regulator said.

Existing registrations and permissions will not convert automatically, the FCA warned. A firm unsure how the rules apply to it should seek independent legal advice.

The sharpest detail concerns overseas providers. A platform established abroad stays outside the trading-platform perimeter when it is unavailable to UK consumers and an authorized UK firm trades on it as principal under the relevant permission. The same operator falls inside the perimeter, and needs authorisation, when that UK firm instead accesses the platform as agent for UK consumers. CryptoSlate reported on Sept. 18 that consumer access plus the UK firm's trading capacity decides the outcome under the FCA's territorial guidance.

A UK consumer in this context means an individual in the UK acting outside a trade, business or profession. The definition is a statutory territorial concept and can differ from client categories elsewhere in the FCA Handbook, the outlet noted.

Custody and staking face separate tests. An overseas provider safeguarding cryptoassets or arranging staking for a UK consumer can be deemed to operate in the UK when it acts independently of a person authorized for that activity. Acting at the authorized person's direction takes the arrangement outside that deeming provision, according to the same account.

Interfaces to automated protocols get no blanket answer. The FCA focuses on whether an identifiable person carries on the elements of a regulated activity by way of business in the UK, which leaves each decentralised setup to be judged on its facts.

The regulator's perimeter manual explains its interpretation of the legislation and does not bind a court, so exchanges, custodians, staking services and interface operators must apply the guidance to their own structures at their own risk.

David Geale, the FCA's executive director for consumers, payments and competition, said firms had asked for this clarity. "We are building a crypto regime that firms, consumers and international partners can trust. Getting ready for regulation starts with understanding how the regime applies to your business," he said in the FCA announcement, as quoted by Securities.io.

The statement follows a consultation that ran from April 15 to June 3, 2026 as CP26/13 and drew 78 responses. Most respondents supported the approach, the FCA page states.

Applications for transitional arrangements run from Sept. 30, 2026 through Feb. 28, 2027. Firms that apply inside the window and meet the conditions may keep operating specified activities under saving provisions while the regulator decides their case. Firms that apply late cannot rely on those provisions and may have to stop the relevant activities until they are authorized. The FCA urged applicants to file early to maximize the covered period.

To win authorisation a firm must show it meets and will keep meeting the minimum standards in the Financial Services and Markets Act, known as the Threshold Conditions. The regulator pointed firms to webinars and its pre-application support service, and told dual-regulated firms to contact the Prudential Regulation Authority as well.

The perimeter guidance caps a rule-writing sequence that began when Parliament passed the underlying regulations in February 2026, pulling a broad range of cryptoasset activities into the FCA's remit for the first time. Until October 2027 the regulator's supervision stays limited to promotions and anti-money laundering controls. Since January 2020, UK crypto businesses defined as exchange or custodian wallet providers have only needed to register, and under the new regime they will instead require full authorisation.

On June 30 the FCA had published final rules on admissions and disclosures with market abuse, stablecoin issuance, regulated cryptoasset activities, prudential standards and the application of its Handbook, numbered PS26/9 through PS26/13. The perimeter guidance builds on that core regime, the policy statement says.

The Government has since published amendments to the legislation with targeted exclusions and clarifications, including a draft instrument that would move activities involving UK-issued qualifying stablecoins out of arranging and dealing and into a future payments regime. The FCA said the changes will not affect most crypto firms, which can use the published guidance to prepare now.

More detail is still coming. The regulator plans to consult in October 2026 on targeted updates covering UK qualifying stablecoins, proprietary trading and market making, certain technology providers, decentralised protocols, custody arrangements involving central securities depositaries and financial promotions. It aims to publish the updated guidance in early 2027.
