UK Crypto Crackdown 2.0: What You Need To Know (August 2025)
A refreshed rule set in August 2025 raises the bar for businesses handling digital assets and related transactions.
Headline changes at a glance:
- Stricter financial promotion and disclosure standards for UK‑facing crypto services.
- Tighter onboarding with source‑of‑funds checks and enhanced KYC.
- Stronger governance and market‑abuse controls for trading platforms.
Who is affected
Exchanges, brokers, custodians, wallet providers and fintechs that offer asset features to UK clients are squarely in scope.
Miners that interact with UK users and retail investors accessing UK‑promoted products are also covered.
Scope and intent
The government aims to restore market integrity and boost consumer protection. Regulators now prioritise faster criminal and civil action where harm is seen.
Operational impacts span onboarding, ongoing monitoring of transactions, incident reporting and custody arrangements.
| Area | Immediate change | Practical effect |
|---|---|---|
| Promotions | Clearer disclosures | Review marketing and product pages |
| Onboarding | Source‑of‑funds checks | Longer client journeys, more documentation |
| Market conduct | Surveillance rules | Enhanced trade monitoring and reporting |
Why “Crackdown 2.0” — and why now?
After years of rapid expansion and repeated misconduct, UK authorities have shifted from permissive testing to firm oversight.
From “wild west” to watchdogs: FCA action and global enforcement momentum
The FCA became the AML/CTF supervisor for UK crypto asset companies in January 2020 under the MLRs. Its gatekeeping has been strict: by 31 March 2024 over 87% of registrations were rejected, withdrawn or refused.
That approach now includes criminal enforcement. A conviction in September 2024 over unregistered ATM operations shows breaches carry real penalties. International cases — including major US actions against wash trading and spoofing — reinforce the need for stronger surveillance and fair trading rules.
HMRC’s tax lens on gains, transactions and undeclared activity
HMRC treats cryptocurrency as taxable. Gains can attract Capital Gains Tax while mining, staking and some payments fall under Income Tax and National Insurance.
“Gatekeeping under the MLRs has tightened access and raised governance standards.”
| Area | Driver | Impact |
|---|---|---|
| Registration | MLRs and FCA scrutiny | High rejection rate; stronger controls |
| Enforcement | Prosecutions and data sharing | Criminal penalties and fines |
| Tax | Exchange reporting to HMRC | More investigations and interest |
Regulators see this as a multi‑year effort to protect consumers and the market while letting legitimate businesses adapt.
The New Regulatory Framework: Key Pillars and Legislation
Parliament and regulators have built a clearer legal architecture to govern digital holdings and related services.
FCA as AML/CTF supervisor under the MLRs
The Financial Conduct Authority has supervised AML/CTF for digital‑asset companies since 10 January 2020 under the MLRs 2017.
Registration requires robust governance, customer due diligence, transaction monitoring and suspicious activity reporting. Over 87% of registrations were rejected, withdrawn or refused to 31 March 2024.
Financial Services and Markets Act 2023
FSMA 2023 brings certain digital holdings within the definition of investment for UK regulated activity.
This change makes permissions, systems and senior accountability central for any firm offering custody, exchange or brokerage services.
Economic Crime and Corporate Transparency Act 2023
The Act expands law‑enforcement powers to search, seize and recover illicit digital assets, amending confiscation and civil recovery rules in the Proceeds of Crime Act 2002.
Property (Digital Assets etc) Bill
The Bill clarifies that digital holdings can be personal property. This supports litigation, insolvency and custody certainty for assets such as tokens and NFTs.
| Instrument | Core change | Practical effect |
|---|---|---|
| MLRs 2017 (FCA) | AML/CTF supervision | High bar for registration; stronger checks |
| FSMA 2023 | Perimeter shift | More companies require permissions and controls |
| Economic Crime Act | Seizure & recovery powers | Faster asset recovery; better victim redress |
| Property Bill | Property status for digital holdings | Clearer legal basis for custody and collateral |
The 2025 rulebook refresh: what’s changing?
The refreshed rulebook focuses on clearer warnings, stronger surveillance and tighter data sharing for higher‑risk transactions.
Financial promotions, consumer duty and disclosure rules for crypto services
Businesses will face stricter promotional rules with prominent risk warnings, explicit fee disclosures and assessments of customer appropriateness.
Providers must disclose volatility, custody arrangements, and tax reporting obligations so retail customers can make informed choices.
Exchange governance and market‑abuse controls
Trading venues must deploy surveillance to detect wash trading, spoofing, and pump‑and‑dump schemes. Recent US actions that charged 18 defendants and seized over $25 million underscore this priority.
Platforms will document controls, incident response plans, and model validation to protect order‑book integrity and fair access to liquidity.
Data, travel rule, and on‑chain analytics
Higher‑risk transactions will trigger implementation of the FATF Travel Rule and enhanced information sharing with regulators and tax authorities.
On‑chain analytics will be used to spot mixers, sanctions exposure and fraud typologies. Exchanges sharing data with HMRC mean companies should prepare for tax transparency requests.
“Documented evidence of compliance — policies, training and audit trails — will be crucial when the FCA supervises business’ activities.”
| Area | Immediate change | Practical step |
|---|---|---|
| Promotions | Clearer disclosures | Update marketing and product pages |
| Governance | Surveillance & reporting | Test alerts; board MI |
| Data | Travel Rule & analytics | Integrate chain monitoring |
What this means for businesses (exchanges, brokers, FinTech’s)
Companies operating trading venues and retail platforms must overhaul policies, controls and disclosure to meet higher regulatory scrutiny.
Firm authorisation and AML readiness
Authorisation demands robust governance, senior‑manager fit‑and‑proper checks and a documented AML framework aligned to the MLRs 2017. The FCA has rejected or withdrawn a high share of registrations, so evidence of effective customer due diligence and transaction monitoring is essential.
Trading surveillance and market practice
Trading surveillance should detect layering, spoofing, wash trading and pump‑and‑dump schemes. Businesses must calibrate alerts, run data quality controls and supply MI to senior management to demonstrate best execution and conflict‑of‑interest management.
Custody and operational resilience
Custody models must segregate client and firm assets, use multi‑sig or cold‑storage, and keep rigorous reconciliation and key management. Operational resilience plans and independent assurance will reduce supervisory risk.
Cross‑border promotions and tax touchpoints
Overseas platforms marketing to UK users must follow local promotion rules or face action. Companies should provide clear tax statements to support HMRC enquiries and train frontline teams on basic tax points, including income from mining and staking.
| Area | Immediate step | Why it matters |
|---|---|---|
| Authorisation | Governance pack & AML programme | FCA scrutiny under MLRs |
| Surveillance | Alert tuning & case management | Detect market abuse |
| Custody | Segregation & key controls | Protect client assets |
What this means for consumers
Platform journeys will change: onboarding may take longer, disclosures will be stronger and fees more transparent.
The shift aims to give retail investors clearer information and better protection when dealing in digital assets. Companies will show prominent risk warnings, detailed fee breakdowns and suitability checks that can add steps at registration and trade time.
Investor experience: more disclosures, potential friction, fees and tax reporting
Users will see clearer messages about volatility, custody and costs. This means occasional delays at verification and on larger withdrawals.
Tax rules must be considered. HMRC treats cryptocurrency as a taxable asset: disposals, swaps, spending and gifts (outside spouses) can trigger Capital Gains Tax.
Income from staking, airdrops or mining is liable to Income Tax and may affect National Insurance. Keep contemporaneous records of dates, GBP values, fees and gains or losses.
Protections and risks: fewer scams, but tighter rules on trading and withdrawals
- Enhanced surveillance and AML checks lower the risk of scams and market abuse.
- Greater verification may slow withdrawals and add documentation requirements.
- Choose platforms that use strong security (2FA, cold storage) and that provide clear statements for HMRC reporting.
“HMRC receives exchange data; prompt reporting and good records reduce the risk of penalties and investigations.”
| Consumer change | Practical impact | Action to take |
|---|---|---|
| Stronger disclosures | Clearer risk and fee information | Compare transparency, not just price |
| More verification | Longer onboarding and withdrawals | Have ID, proof of address and source-of-funds ready |
| Tax reporting | HMRC can request exchange data | Use tools like Koinly or CoinTracker; file by 31 January |
| Surveillance | Fewer scams and unfair trading | Prefer regulated platforms with clear support routes |
Timeline: what’s next (H2 2025-2026)
Regulators have signalled a sequenced roadmap that will convert policy into firm-level requirements over the next 18 months.
Consultations and secondary legislation: sequencing of new rules
The second half of 2025 and early 2026 will see consultations followed by secondary instruments that set operational standards.
Companies should expect staged deadlines for onboarding, promotions and surveillance requirements that translate statute into processes.
Enforcement milestones: prosecutions, supervision and market clean‑up
Enforcement will continue. The FCA has already rejected over 87% of registrations up to 31 March 2024 and secured a conviction on 30 September 2024.
International actions — including a US case that charged 18 defendants and seized more than $25 million — will inform supervisory priorities at exchanges and custodians.
What to watch: FCA guidance, HMRC updates and progress of the Property Bill
The Property (Digital Assets etc) Bill had its first reading in the House of Lords on 11 September and seeks to confirm property status for digital assets and cryptocurrency.
Monitor FCA Dear CEO letters and HMRC technical notes. Businesses should run gap analyses, build staged implementation plans and explain interim controls to customers as rules land.
Conclusion
Recent measures balance deterrence with clearer rules that reward good governance and transparency.
The shift is as much about clarity and credibility as deterrence. Compliant businesses can become a trusted part of the financial system while high‑quality products find room to grow.
Companies and individuals should focus on robust governance, accurate tax reporting and prompt remediation when gaps appear. Miners and validators must plan for tax on rewards and due diligence around counterparties and payouts.
Stakeholders should engage with consultations and industry bodies and follow guidance such as the SEC analysis on regulatory implications via this SEC approach to regulation. Those who invest early in controls, education and transparency will be best placed for orderly trading and resilient assets.
