The UK Financial Conduct Authority published final cryptoasset perimeter guidance on September 16, 2026, naming which digital-asset activities will require FCA authorization ahead of a September 30 application gateway.
The guidance, issued as policy statement PS26/18, names five regulated activities: issuing qualifying stablecoins, operating trading platforms, dealing and arranging deals, safeguarding cryptoassets, and arranging staking. It arrives two weeks before the gateway opens, though the full regime doesn’t take effect until October 25, 2027.
David Geale, the FCA’s executive director of consumers, payments and competition, said in the regulator’s announcement that it is building a crypto regime that firms, consumers, and international partners can trust, and that getting ready for regulation starts with understanding how it applies to a specific business.
What PS26/18 Names as Regulated Activity
The guidance follows legislation the UK government set out in February 2026, after the Cryptoasset Regulations passed Parliament on February 4. The FCA finalized its core cryptoasset rules in June 2026 through earlier policy statements, with PS26/18 building on that foundation to clarify the regulatory perimeter.

The government has also published targeted amendments introducing exclusions covering UK-qualifying stablecoins, proprietary trading and market making, certain technology providers, decentralised protocols, and financial promotions.
Who the Guidance Applies To
The guidance applies to firms carrying out, or planning to carry out, any of the five named activities in the UK. That includes already-authorized firms needing extra permissions, firms registered under the Money Laundering Regulations, e-money issuers, traditional finance firms exploring crypto markets, and overseas firms serving UK consumers, a scope worth understanding alongside a comparison of UK versus U.S. stablecoin regulation.
Crucially, the regulator warned that existing registrations and permissions will not convert automatically under the new regime. Firms are being told to read the guidance now and determine whether they need full FCA authorization or a variation of their existing permission, rather than assuming their current registration carries over.
Why the September 30 Application Window Matters
The gateway opening September 30, 2026 gives firms roughly 13 months to secure authorization before the regime takes effect October 25, 2027. Firms using transitional provisions must apply by February 28, 2027, well ahead of the regime’s actual start.
Applicants can access pre-application support meetings and FCA webinars, and the regulator plans to consult on further Perimeter Guidance Manual amendments in October 2026, aiming to publish final guidance in early 2027 as the underlying statutory instrument develops.
How This Extends Beyond Anti-Money Laundering Rules
Before this framework, crypto firms in the UK primarily interacted with the FCA through a temporary registration regime introduced in 2021, focused mainly on anti-money laundering obligations. The new regime expands that scope into governance, operational controls, and consumer protection, covered further in a guide on UK stablecoin regulation and what it means for USDT and USDC.
The FCA has not said that every crypto-related activity will automatically require authorization, since regulatory treatment depends on which of the five named activities a firm’s specific services fall under.
What Firms Need to Do Before the Gateway Opens
The next step is for firms to map their business models against the five named regulated activities well ahead of the application gateway, given how far in advance it opens relative to the regime’s in-force date. The FCA has advised firms unsure how the rules apply to seek independent guidance rather than wait until closer to the 2027 deadline.
The regulator’s approach will also offer insight into how the UK balances crypto innovation with financial-market oversight as digital-asset activities become more integrated with traditional financial services.
What this means for you: The FCA’s cryptoasset perimeter guidance signals that crypto businesses operating in the UK now have named, specific activities to check their operations against, rather than a general registration requirement. For users, the changes could mean more oversight and accountability from regulated firms, though the practical impact will depend on how many firms secure authorization before the 2027 deadline.
