At a Glance
At a Glance - The FCA’s PS26/18 guidance defines the regulatory perimeter for cryptoasset activities that will require FCA authorisation from 25 October 2027, and it details a transitional application window that opens on 30 September 2026 and closes on 28 February 2027.
The FCA is expanding the regulated perimeter to cover activities such as safeguarding cryptoassets, operating trading platforms, arranging deals and staking. Existing permissions under the Money Laundering Regulations, Payment Services Regulations or Electronic Money Regulations will not automatically transfer, meaning firms must assess whether a new FSMA authorisation or a variation of permission is needed.
The guidance is aimed at crypto‑focused firms, traditional finance organisations exploring crypto markets, payment service providers and any entity that registers under the MLRs. It links to the broader cryptoasset regime published on 30 June 2026 and signals the FCA’s intent to support a smooth transition through webinars, pre‑application support and ongoing engagement with the PRA.
What the Final Rules Change
New regulated cryptoasset activities
From 25 October 2027 the Cryptoasset Regulations introduce a set of regulated activities, including safeguarding cryptoassets, operating a trading platform, arranging deals and staking, which will require FCA authorisation unless an exemption or transitional provision applies.
Transitional application window
The FCA has opened a specific window for firms wishing to use the savings and transitional run‑off provisions; applications can be submitted from 30 September 2026 and must be received by 28 February 2027. This window is the only period during which firms can rely on the transitional provisions.
Interaction with existing regimes
Existing registrations under the Money Laundering Regulations, Payment Services Regulations or Electronic Money Regulations do not convert automatically to FSMA authorisation. Firms must map current permissions against the new cryptoasset activities and determine whether a variation or fresh authorisation is required, while continuing to satisfy threshold conditions and financial‑crime rules.
Implementation Dependencies
Firms should begin by mapping each of their crypto‑related services against the activity list in Chapter 4 of the guidance. This mapping will identify whether a service falls within the regulated perimeter and, if so, which specific permission - for example, safeguarding or arranging - is required. The analysis must consider the interaction with the Money Laundering Regulations, as the FCA expects continued compliance with AML rules post‑authorisation. MEMA recommends establishing a cross‑functional working group that includes compliance, legal, product and technology to produce a definitive perimeter assessment within the next four weeks.
The application window creates a hard deadline for firms that wish to rely on the savings and transitional provisions. Preparation should include gathering evidence of existing controls, drafting a variation request where an existing FSMA permission is being extended, and arranging pre‑application meetings (PASS). Dual‑regulated firms must also coordinate with the PRA. MEMA advises scheduling the PASS booking by early November 2026 to allow sufficient time for FCA feedback before the 28 February 2027 cut‑off.
Who Must Act
The guidance directly targets firms that currently carry out or plan to carry out regulated cryptoasset activities in the UK. This includes crypto‑asset custodians, trading platform operators, arrangers of staking services, issuers of electronic money, payment service providers and traditional finance firms that are testing crypto markets overseas. It also applies to entities already authorised under the FSMA, as well as those registered under the Money Laundering Regulations, who may need additional permissions for crypto activities.
While the PS is relevant to any organisation interested in the evolving cryptoasset framework, the FCA explicitly states that the guidance is for firms that will be carrying on regulated cryptoasset activities by way of business in the UK. Firms that are merely monitoring the market but do not intend to undertake a regulated activity are not required to seek authorisation, although they should stay informed of future consultations.
Board Assurance
The board should ask whether any current business lines will fall within the newly defined regulated cryptoasset activities and, if so, whether the firm holds the appropriate FSMA authorisation or a valid exemption. Evidence required includes the activity mapping, legal opinions on exemptions and a timeline for any required authorisation applications, all of which should be presented at the next board risk committee meeting.
The board must also consider the operational impact of transitioning from MLR registration to FSMA authorisation, including the need to satisfy threshold conditions, maintain AML controls and align reporting with the FCA’s financial‑crime rules. Documentation of the transition plan, resource allocation for the authorisation process and confirmation of PRA engagement for dual‑regulated entities will provide the assurance the board needs to endorse the transition strategy.

Frequently asked questions
Can existing permissions under the Money Laundering Regulations be used instead of a new FCA authorisation?
No. PS26/18 makes clear that existing registrations or permissions under the Money Laundering Regulations, Payment Services Regulations or Electronic Money Regulations will not automatically convert to FSMA authorisation. Firms must assess each crypto activity against the new perimeter and apply for a fresh authorisation or a variation where required.
What is the purpose of the transitional application window and when does it close?
The transitional window, opening on 30 September 2026 and closing on 28 February 2027, allows firms to apply for authorisation while relying on the savings and transitional run‑off provisions. This window is the only period during which firms can benefit from those provisions, and the FCA encourages early engagement through its pre‑application support service. This answer is grounded in PS26/18.
