FCA sets UK boundary for offshore crypto platforms ahead of 2027

The Financial Conduct Authority published final perimeter guidance on Sept. 16, 2026, stating overseas crypto trading platforms, custodians and staking providers will require UK authorisation when they serve UK consumers or when an authorised UK firm accesses them as an agent. The tests apply before new cryptoasset activities take effect on Oct. 25, 2027.

The guidance defines a “UK consumer” as an individual in the UK acting outside a trade, business or profession. Firms must apply ordinary territorial principles and then consider Section 418 deeming provisions, which can bring offshore activity into the UK regulatory perimeter when it involves a UK consumer. The outcome depends on how UK customers reach services and how any authorised UK firm interacts with the overseas provider.

For crypto trading platforms the guidance sets two outcomes. If an authorised UK firm trades on an overseas platform as principal under its permission, the platform remains outside the UK platform activity perimeter when it is unavailable to UK consumers. If the authorised firm accesses the platform as agent on behalf of UK consumers, the offshore operator can be brought inside the UK perimeter and will require authorisation.

Custody and staking services are subject to activity-specific tests. An overseas custodian or staking arranger can be deemed to be operating in the UK when it safeguards cryptoassets or arranges staking for a UK consumer and acts independently of a person authorised for that activity. If the overseas provider operates at the direction of an authorised UK firm, the arrangement can fall outside the deeming provision.

The regulator says automated-protocol interfaces and decentralised finance structures will be assessed case by case, with attention on whether an identifiable person is carrying on regulated activity by way of business in the UK.

The FCA opens an application window for transitional arrangements from Sept. 30, 2026 through Feb. 28, 2027. The new activities enter the perimeter on Oct. 25, 2027. The guidance states existing registrations and permissions will not convert automatically and some firms may need to vary permissions to cover the new activities.

The guidance appears in the Perimeter Guidance manual (PERG) and explains the FCA’s interpretation of the legislation. PERG guidance does not have binding force in court, so operators must apply the tests to their specific business models and facts.

The guidance includes compliance milestones and legal triggers for overseas providers. It notes firms with exposure to UK retail customers, those dealing with authorised UK firms, and providers of custody or staking services should map customer access routes, clarify whether any identifiable person carries regulated activity in the UK and consider applying for transitional permissions during the open window.
