UK Crypto Rules Raise Privacy Concerns

New cryptocurrency regulations proposed in London have sparked debate over their impact on privacy rights, a fundamental aspect of human rights law in the United Kingdom. The Financial Conduct Authority (FCA) has outlined plans to tighten oversight of digital asset firms, aiming to reduce money laundering and fraud. However, critics argue these measures could infringe on individual privacy, protected under Article 8 of the European Convention on Human Rights (ECHR), which guarantees the right to private and family life.

The FCA’s proposal, announced in July 2025, would require cryptocurrency exchanges operating in the UK to collect detailed user data, including transaction histories and wallet addresses, to comply with anti-money laundering (AML) regulations. This follows a reported rise in crypto-related fraud, with losses estimated at around £1.2 billion in 2024, according to Action Fraud. The rules aim to align the UK with global standards set by the Financial Action Task Force (FATF), which mandates enhanced monitoring of digital transactions.

Privacy advocates, including the human rights organisation Liberty, have raised alarms about the potential for mass data collection. They argue that mandatory data retention could lead to surveillance overreach, undermining the right to privacy enshrined in the Human Rights Act 1998. A spokesperson for Liberty stated, “Requiring firms to store sensitive financial data risks creating a surveillance environment, where citizens’ financial autonomy could be undermined.”

 This concern echoes challenges to past UK surveillance laws, such as the Investigatory Powers Act, which Liberty contested for violating ECHR Article 8 and Article 10 (freedom of expression).

The proposed regulations also mandate that crypto firms report suspicious transactions to the National Crime Agency (NCA). While supporters say this will deter illicit activities, detractors warn it could discourage legitimate users from adopting cryptocurrencies, stifling innovation. The UK’s blockchain industry, valued at approximately £4.5 billion in 2025, employs over 50,000 people, according to a report by the British Blockchain Association. Critics warn that excessive regulation could drive firms to jurisdictions with less stringent rules, such as Switzerland or Singapore.

The debate has drawn parallels to earlier human rights cases. In 1996, the European Court of Human Rights ruled in Goodwin v United Kingdom that forcing journalists to disclose sources violated Article 10, citing a “chilling effect” on free expression. Similarly, privacy advocates argue that mandatory crypto data collection could chill financial freedom, as users may self-censor transactions to avoid scrutiny. A 2022 Ministry of Justice consultation on revising the Human Rights Act highlighted tensions between privacy and public safety, noting that courts must balance these rights carefully.

Industry leaders have called for a balanced approach. The CEO of London-based crypto exchange Coinbase UK, Sarah Johnson, urged policymakers to consider privacy-enhancing technologies, such as zero-knowledge proofs, which allow verification without exposing sensitive data. “The UK can lead in responsible crypto regulation without sacrificing human rights,” Johnson said at a recent fintech conference in Canary Wharf. The FCA has promised to review feedback from stakeholders before finalising the rules by December 2025.

Public response has been mixed. A YouGov poll conducted in August 2025 found that 62 per cent of Britons support stricter crypto regulations to prevent crime, but 45 per cent are concerned about government overreach into personal finances. The issue has also sparked discussion in Parliament, with MPs from the Conservative and Liberal Democrat parties emphasising the need to protect privacy while addressing criminal misuse of digital assets. The Labour Party, while supportive of regulation, has faced criticism for not addressing privacy concerns explicitly.

The FCA’s proposals come amid global trends in crypto regulation. The European Union introduced similar rules in 2024, requiring exchanges to verify user identities for transactions above €1,000. The UK’s approach is seen as comparatively stricter, with potential fines of up to £7 million for non-compliant firms. This has led to calls for clearer guidance on how data collection will align with the UK’s human rights obligations.

As the consultation period continues, balancing financial security with individual privacy remains a contentious issue. The outcome will likely shape the UK’s role in the global crypto market and its commitment to upholding human rights in the digital age. Stakeholders, including privacy advocates and industry leaders, urge the government to ensure that any new rules respect the principles of proportionality and necessity, as required by the ECHR.
