The Financial Conduct Authority said on 17 September that it and partner agencies had taken further action against illegal peer-to-peer crypto trading across multiple London locations. The operations took place on 10 September under the UK’s money-laundering regulations. The notice documents a focused enforcement effort, not a blanket conclusion about every peer-to-peer crypto service.

The FCA says it used current AML powers with partner agencies to disrupt illegal trading operations.

The press release does not establish that all peer-to-peer crypto activity is unlawful or describe every case in the market.
The update concerns multi-agency action at several London locations
The FCA’s notice says it worked with partners in the UK and abroad to disrupt illegal peer-to-peer crypto trading at multiple locations in London. It dates the operational action to 10 September and says the work was conducted under the Money Laundering, Terrorist Financing and Transfer of Funds Regulations 2017.

The announcement is about enforcement against activity the FCA characterizes as illegal. It does not say that every peer-to-peer transaction, every non-custodial wallet or every crypto-to-cash service is unlawful. Firms and users still need to understand which rules apply to their own role and activity.
The FCA also notes that crypto remains a high-risk investment and that the UK’s broader crypto regime has not yet begun. The regulator says crypto remains largely unregulated in the UK, apart from existing anti-money-laundering and financial-promotion requirements, until October 2027.

Enforcement is active while the wider authorization regime is still ahead
The notice illustrates that current AML and financial-promotion rules can apply before the future UK crypto authorization regime starts. That makes present-day permissions and activity-specific obligations distinct from the application process scheduled for the coming regime.
For users, an in-person or online P2P label does not answer whether an intermediary is registered, whether the arrangement is lawful or how customer funds are handled. The FCA directs consumers to its Firm Checker for permissions. That check is a starting point; it does not verify every transaction or remove market and counterparty risk.

The regulator’s action may influence how firms document customer onboarding, transaction monitoring and referral processes. Those are practical implications of the enforcement update, not new rules announced in the press release. The FCA’s notice does not quantify the full size of the activity it disrupted.
Check the present perimeter instead of relying on future-regime headlines
Identify who is arranging, executing or promoting a P2P transaction and in which jurisdiction. Check the FCA register for the exact legal entity and permissions, read the regulator’s current AML guidance and confirm who controls the assets at every step. A firm’s marketing use of “peer-to-peer” does not settle its legal status.
An alternative explanation is that a lawful transfer between individuals may be mistaken for the kind of activity targeted by enforcement. The notice concerns specific operations and alleged illegal activity; facts about the parties, services and legal obligations matter before applying it to another case.
Continue to separate current AML and promotion controls from the future FSMA crypto regime and its authorization window. New rules, dates or enforcement outcomes should be checked against the FCA’s official pages as they are published. The September update is evidence of action at named locations, not a complete map of every UK crypto service.
