The UK Financial Conduct Authority, HM Revenue & Customs and the Metropolitan Police Service took enforcement action at three London premises suspected of hosting unregistered peer-to-peer crypto businesses and issued cease-and-desist letters requiring the operators to stop. The FCA said no peer-to-peer crypto businesses currently operating by way of business are registered with it in the UK, although individuals conducting personal transactions do not need registration. Steve Smart, the FCA's executive director of enforcement and market oversight, warned that unregistered operators should assume they are being monitored. The regulator said such businesses can operate outside safeguards designed to detect and prevent money laundering. The action was the FCA's second coordinated crackdown on illegal peer-to-peer crypto trading this year, following an April operation whose evidence is supporting criminal investigations and other enforcement action. The latest move follows earlier action against HTX, when major app stores were asked to restrict access to the platform for UK consumers, as well as new guidance on the UK's incoming cryptoasset regime. The FCA has also opened a call for input on tokenised gold in UK wholesale markets and advises consumers to use its Firm Checker to verify firms' registration and permissions.
