FCA Leads First UK Crackdown on Illegal Peer-to-Peer Crypto Trading

The UK Financial Conduct Authority says it has carried out its first coordinated operation to disrupt illegal peer-to-peer crypto trading, targeting eight London premises alongside HM Revenue & Customs and the South West Regional Organised Crime Unit. According to the FCA, cease-and-desist letters were issued at each site and evidence gathered during the visits is supporting ongoing criminal investigations.

The regulator also clarified an important line for traders: peer-to-peer crypto activity carried out on a personal basis does not require FCA registration, but anyone doing it by way of business in the UK must be appropriately registered. The FCA said there are currently no FCA-registered peer-to-peer crypto businesses operating in the UK.

That distinction matters because informal-looking trading activity can still trigger regulatory exposure if it is effectively being run as a business. The FCA framed the issue not only as a conduct problem but also as a financial-crime risk, warning consumers to deal only with firms on its register and to remember that crypto remains a high-risk investment.

Why it matters

For active traders, this is a sign that UK enforcement around crypto is moving beyond website warnings and into physical disruption of unregistered activity. It raises the compliance risk for anyone using off-platform or cash-style peer-to-peer channels that sit outside normal broker controls.

What to watch next

The next signal is whether these inspections lead to formal charges, further raids or wider action against unregistered crypto businesses. Traders should also watch whether the FCA publishes more guidance on where casual activity ends and “by way of business” begins.
