What it claims

On 16 September 2026 the FCA published guidance — Policy Statement PS26/18 “Cryptoasset perimeter guidance” — explaining how the law underpinning the UK’s future cryptoasset regime applies to firms and which activities may require FCA authorisation [S-2026-09-16-fca-cryptoasset-perimeter-guidance-ps26-18]. The covered activities include issuing qualifying stablecoins, operating cryptoasset trading platforms, dealing and arranging deals, safeguarding cryptoassets and arranging cryptoasset staking [S-2026-09-16-fca-cryptoasset-perimeter-guidance-ps26-18].

Timeline: applications for authorisation open from 30 September 2026 and the regime comes into force on 25 October 2027; the FCA frames the guidance as what firms “need now” to prepare, supported by pre-application discussions and webinars [S-2026-09-16-fca-cryptoasset-perimeter-guidance-ps26-18]. The guidance follows the FCA’s June 2026 final rules package (the vault’s S-2026-06-30-fca-cryptoasset-regime / PS26/13, which applied Consumer Duty, SYSC, SM&CR, COBS, DISP/FOS, CASS and reporting to regulated cryptoasset activities) [S-2026-06-30-fca-cryptoasset-regime]. The Government has published amendments to the underlying legislation (targeted exclusions and clarifications for certain technical-services providers); the FCA will consult in October 2026 on targeted updates to the perimeter guidance covering UK qualifying stablecoins, proprietary trading and market making, certain technology providers, decentralised protocols, safeguarding involving central securities depositaries, and financial promotions [S-2026-09-16-fca-cryptoasset-perimeter-guidance-ps26-18].

Notable quotes

“New guidance from the Financial Conduct Authority (FCA) will help firms understand how the law underpinning the UK’s future cryptoasset regime applies to their business. It also sets out which activities may require FCA authorisation.” — FCA press release, 16 September 2026

“Getting ready for regulation starts with understanding how the regime applies to your business. This guidance gives firms the clarity they’ve asked for so they can prepare with confidence.” — David Geale, FCA executive director of consumers, payments and competition, 16 September 2026

What’s speculative vs. asserted

• Asserted (primary FCA press release, fetched in full): the 16 Sep 2026 publication of perimeter guidance (PS26/18); the covered activities; the 30 Sep 2026 authorisation gateway and 25 Oct 2027 regime commencement; the October 2026 follow-up consultation and its scope; the link back to the June 2026 rules.
• Not extracted this run (⚠️): the detailed perimeter-determination content of the PS26/18 document body — only the press-release summary was captured. Treat activity-by-activity perimeter specifics as pending review of the PS26/18 PDF.
• Relevance note: not AI/data-governance/model-risk specific; recorded as a Regulatory Readiness & Evidence / Governance Framework Design data point consistent with the vault’s broader FCA crypto-regime tracking.

Topics this feeds

• FCA — Financial Conduct Authority — a further authorisation-readiness milestone in the UK cryptoasset regime.
• Operational Resilience and Third Party Risk — the regime it belongs to applies operational-resilience standards to cryptoasset firms.
• Suggested future Topic page: FCA Cryptoassets Regime — now supported by a second dated source (June 2026 rules + Sep 2026 perimeter guidance); promote when synthesis value justifies.

Open questions raised

• What the PS26/18 body says about the treatment of the harder perimeter cases (decentralised protocols, technology providers, staking) beyond the press-release summary.
• How the October 2026 consultation will change the perimeter, and whether firms preparing applications from 30 Sep face a moving target.
• Whether this regime warrants its own Topic page yet, or remains tracked under the FCA entity page.
