The United Kingdom spent 2025 and 2026 converting a consultation program into a complete rulebook, and is now in the gap between enactment and commencement. Parliament made the Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026 on February 4, 2026, bringing a broad set of cryptoasset activities inside the FCA's regulatory perimeter for the first time. On June 30, 2026 the FCA published the core final rules as five policy statements, PS26/9 through PS26/13, covering admissions and disclosures, a market abuse regime for cryptoassets, stablecoin issuance, regulated cryptoasset activities, and a bespoke prudential regime, together with guidance on the consumer duty, international firms, and operational resilience. The authorisation gateway opens on September 30, 2026, and the regime comes into force on October 25, 2027.
Until then, the older, narrower layer still governs: cryptoasset firms must register with the FCA under the Money Laundering Regulations 2017, and since October 2023 the financial promotions regime has applied to crypto marketing, with a 24-hour cooling-off period and risk warnings for retail. Firms that apply during the gateway window may generally continue operating while the FCA processes their application, even past commencement; firms that do not apply must stop serving UK customers when the regime begins. Systemic sterling stablecoins get a second supervisor: the Bank of England published its policy approach on June 22, 2026, and a joint BoE-FCA paper on June 30 splits responsibilities where an issuer reaches systemic scale.
The design choice worth noticing is that the UK declined to copy MiCA. Rather than a standalone code, cryptoassets are slotted into the existing FSMA architecture: the same general prohibition, threshold conditions, senior managers regime, and consumer duty that govern banks and investment firms, adapted through a dedicated sourcebook. That makes the UK regime heavier per firm than MiCA in places, particularly on prudential requirements, where capital is set as the highest of a fixed minimum, a fixed-overhead requirement, or activity-based K-factors calibrated to crypto exposures.
The instruments
Financial Services and Markets Act 2000 (Cryptoassets) Regulations 2026
The perimeter instrument. Creates new regulated activities for cryptoassets under FSMA, including operating a trading platform, dealing, arranging, custody, and stablecoin issuance, requiring firms serving UK customers to be FCA-authorised. Made by Parliament on February 4, 2026; commences October 25, 2027. Built on the powers of the Financial Services and Markets Act 2023, which first brought cryptoassets within the definition of specified investments.
FCA final rules for the cryptoasset regime (PS26/9–PS26/13)
Five policy statements finalise the rulebook: PS26/9 on admissions and disclosures and the market abuse regime for cryptoassets (MARC); PS26/10 on stablecoin issuance, including backing-asset and redemption rules; PS26/11 on regulated cryptoasset activities including trading platforms, intermediaries, custody, and staking; PS26/12 establishing the prudential regime (COREPRU/CRYPTOPRU) with K-factor capital and wind-down planning; and PS26/13 applying the wider FCA Handbook. Finalised guidance covers the consumer duty, international firms and branches, and operational resilience; two prudential guidance consultations closed July 30, 2026.
Bank of England regime for systemic sterling stablecoins
Where a sterling-denominated stablecoin reaches systemic scale, the Bank of England becomes supervisor under the Banking Act 2009 recognition framework as amended by FSMA 2023, with a draft Code of Practice consulted alongside the policy statement. The joint approach paper allocates responsibilities between the Bank and FCA and describes when dual supervision applies.
Financial Services and Markets Act 2023 (cryptoasset provisions)
The enabling statute: brought cryptoassets within the scope of regulated financial services activity, created the framework for regulating fiat-backed stablecoins and payment systems, and gave Treasury the powers used to make the 2026 Regulations.
Money Laundering Regulations 2017: cryptoasset registration
The current gateway: cryptoasset exchange and custodian wallet providers must register with the FCA for AML supervision before operating in the UK. The FCA has rejected or seen withdrawn a large majority of applications since 2020. Registration continues until the 2027 regime supersedes it for authorised firms.
Financial promotions regime for cryptoassets
Since October 8, 2023, marketing qualifying cryptoassets to UK consumers requires approval by an authorised person, an FCA-registered firm's own communication, or an exemption, with mandatory risk warnings, a 24-hour cooling-off period for first-time investors, and a ban on incentives to invest.
Questions people ask
When does crypto become regulated in the UK?
The full regime commences October 25, 2027. The rules are already final (published June 30, 2026), and the FCA begins taking authorisation applications on September 30, 2026. AML registration and the financial promotions rules apply now.
What happens to firms that don't apply before commencement?
Firms that submit a completed application during the gateway window can generally keep operating while the FCA decides, even past October 2027. Firms that do not apply must cease regulated cryptoasset activity with UK customers at commencement or commit a criminal offence.
Is the UK regime the same as MiCA?
No. The UK integrates crypto into its existing FSMA framework, applying the senior managers regime, consumer duty, and a bespoke prudential sourcebook, rather than enacting a standalone code. Coverage is broadly similar; the mechanics, capital treatment, and supervisory style differ, and there is no EU-style passport between the two.
