HM Treasury’s new crypto rules under FSMA 2000
In December 2025, the HM Treasury introduced the Financial Services and Markets Act 2000 (cryptoassets) Regulations 2025 with an aim to bring new cryptoasset activities within the regulatory remit. The new crypto rules proposal includes:
- Backing cryptoassets firms to invest and grow in the UK within the regulatory perimeter
- Proportionate rules coming into force from 2027
- Bringing cryptoassets into the scope of similar rules of stocks & shares
FCA roadmap for crypto assets
For years, the FCA has been planning to widen the scope of regulated crypto activities, including activities with stablecoins. Following the HM Treasury proposal, the FCA announced a roadmap for crypto assets on 16th December 2025 and released three consultation papers.
These consultations provide insights into FCA’s ongoing expansion to set up a comprehensive regulatory regime for cryptoasset firms. We can expect possible regulatory developments like:
- Stricter protections, like imposing clear warnings and structured onboarding processes.
- Improvement in scrutinizing crypto firms that helps reduce fraud.
- Restrictions on higher-risk products may be subject to additional rules (like crypto lending features, etc.).
- Imposing more transparency in customer asset safeguarding and crime controls.
Is cryptocurrency trading legal in the UK in 2026?
Yes, Firms that operate crypto exchanges, custodial services, or any other crypto-related services must register with the FCA under the UK’s Money Laundering Regulations (MLR). This is a mandatory requirement before they start to legally operate the firm in the UK.
Provided the nature and type of assets crypto firms operate, the following regulations apply to the UK-based crypto exchanges, custody providers, OTC brokers, wallets, and other virtual asset service providers. The multiple governing aspect clearly proves the UK crypto asset legality.
| Regulating Authorities | Purpose |
|---|---|
| FCA – Financial Conduct Authority | Governs the registration of crypto firms and oversees AML/CFT compliance |
| HMT – HM Treasury | Sets the regulatory framework and strategies for crypto trading |
| The Bank of England | Involves regulating stablecoins and the digital asset ecosystem |

What UK crypto activities are restricted or banned?
Before knowing what crypto activities are banned, it is essential to learn what FCA registration does not protect you from:
- No FSCS protection for crypto losses
- No compensation if the crypto price collapses
- No protection against personal wallet mistakes
Operating crypto services targeting UK consumers without FCA registration under the Money Laundering Regulations is unlawful. Once the new cryptoasset regime is implemented, firms undertaking regulated crypto activities will also be required to obtain authorisation under FSMA. Currently, the following are the crypto activities restricted or banned in the UK:
- Operating crypto services such as exchanges, custody, or issuing stablecoins without FCA registration (and future authorisation, once implemented)
- Operating crypto-fiat ATM machines, staking, and lending services without FCA authorisation
- Marketing or offering crypto derivatives for retail clients
- Financial promotions without FCA approval
However, individual investors can buy, sell, or hold crypto, use their own wallets for peer-to-peer transactions, and trade crypto for investment use cases on FCA-registered platforms. Going forward to 2026, we expect:
- Cryptoasset lending and borrowing products may be restricted for retail clients.
- DeFi activities may remain outside the initial regulatory perimeter.
