Binance Faces £150M UK Lawsuit as MiCA EU Exit Takes Effect

On 30 June 2026, a group of investors filed a £150 million claim against Binance in London's High Court, alleging the exchange offered unauthorised derivative products to UK retail clients between 2019 and 2020. The action landed one day before Binance was required to withdraw from EU markets under the Markets in Crypto-Assets Regulation (MiCA), having failed to secure a licence before the July 1 deadline. The two events, arriving within 24 hours of each other, concentrate legal and regulatory risk around the exchange at a pivotal moment and carry direct implications for accounting firms, auditors, and CFOs with client or counterparty exposure to Binance.

The UK High Court Claim: What Is Alleged

Core allegations and the defendants named

The claimants, described by their legal representatives at KP Law as ordinary people who committed significant savings, allege that Binance offered leveraged derivative products in the UK without authorisation from the Financial Conduct Authority. The alleged conduct covers a period when Changpeng Zhao was founder and chief executive of the exchange. Defendants named in the proceedings include Zhao personally, Binance's Cayman Islands entity, and the UAE-registered Nest Exchange, as well as unnamed individuals said to have operated the Binance trading platform.

Individual losses claimed range from tens of thousands to several million pounds. A partner at KP Law stated publicly that the firm intends to hold both the exchange and its founder to account for the financial harm suffered by clients.

Binance's stated position

Binance issued a brief public response, stating it would defend against the claims through the appropriate legal process and reiterating its commitment to operating in accordance with applicable law. No admission of liability has been made.

The MiCA Deadline: Why Binance Lost EU Access

The licence application that did not proceed

Binance had been in advanced discussions to obtain a MiCA crypto-asset service provider (CASP) licence through a Greek regulator. The application was withdrawn on 26 June 2026, just days before the July 1 deadline. According to reporting by Protos, citing an undisclosed source, European Central Bank President Christine Lagarde was said to have directly intervened with Greece's regulator before the application could be approved. The ECB has not publicly confirmed or commented on those claims.

Zhao himself indicated in an interview that two EU member states had been competing to host Binance's application before political pressures intervened. Those claims remain unverified. For context on what CASP authorisation under MiCA now entails for any exchange operating in the EU, see our earlier analysis of MiCA transitional period expiry and what CASP authorization now requires.

Where Binance stands from 1 July 2026

Binance's Head of Europe and UK, Gillian Lynch, stated publicly that the exchange is not leaving Europe. CEO Richard Teng issued a statement on 1 July confirming the team is working with regulators to navigate the transition and intends to secure a MiCA licence in the coming months. Until that licence is granted, Binance is not permitted to provide crypto-asset services to clients in EU member states as a MiCA-authorised CASP. The gap between intent and licensed status is material for compliance purposes.

Compliance and Risk Implications for Professional Firms

Counterparty risk assessment

Any accounting firm or corporate treasury that has recorded client assets, trading activity, or balances on Binance needs to revisit its counterparty risk assessment. The combination of active High Court litigation, a named UAE-registered entity as defendant, and a current absence of EU CASP status raises questions about the exchange's operational and legal standing across multiple jurisdictions simultaneously. Firms preparing financial statements or providing audit opinions where Binance balances are material should document the basis for any going-concern or recoverability judgements carefully.

UK regulatory exposure for prior derivative activity

The FCA has consistently taken the position that offering derivatives referencing crypto-assets to UK retail clients requires authorisation under the Financial Services and Markets Act 2000. The period covered by the lawsuit, 2019 to 2020, predates the FCA's 2021 ban on crypto derivatives for retail consumers, but the authorisation requirement existed throughout. Firms advising clients who traded on Binance during that window should consider whether those clients have a potential claim and what documentation they hold. For a current picture of how the FCA's finalized UK crypto regulatory framework affects authorized firms, the obligations have only become more explicit since that period.

UAE entity and cross-border structuring considerations

The inclusion of Nest Exchange, a UAE-registered entity, as a named defendant is significant for firms operating in or with counterparties in the UAE. It signals that claimants and their advisers are prepared to pursue legal action across multiple corporate structures and jurisdictions. Firms conducting AML or counterparty due diligence should note that group structures involving UAE-registered entities remain subject to scrutiny; the UAE's continued progress on FATF compliance does not reduce individual due diligence obligations.

What Firms Should Do Now

Immediate steps

Document all current and historical client balances held on Binance, noting the entity through which those balances are held. Verify whether any EU-domiciled clients are still accessing Binance services after 1 July 2026 and, if so, assess whether that access creates a regulatory or contractual risk for your firm. Update counterparty risk registers to reflect the pending litigation and the absence of current MiCA authorisation. Engage with clients who may have traded Binance derivatives between 2019 and 2020 to assess whether they are aware of the claim and whether they hold relevant records.

For firms with broader AML obligations, the cross-jurisdictional nature of this enforcement cluster, covering UK High Court proceedings, EU licence failure, and UAE entity involvement, is a reminder that transaction monitoring and source-of-funds documentation for crypto exchanges cannot rely on brand recognition alone. The due diligence framework applied to any exchange should be substance-based.
