The UK’s Financial Conduct Authority (FCA) has significantly expanded its enforcement of financial promotion regulations, specifically targeting high-risk investments like cryptoassets and foreign exchange trading. Recent landmark legal actions include High Court proceedings against the exchange HTX and the successful prosecution of several high-profile reality TV stars for promoting illegal schemes on social media. These "finfluencers" received criminal convictions and fines for providing unauthorised investment advice to millions of followers without proper disclosure or expertise. To support this crackdown, the FCA issued updated guidance detailing how digital marketing must be fair, clear, and not misleading, even within private chatrooms or short-form videos. Firms and individuals now face stricter requirements for risk warnings, cooling-off periods, and appropriateness testing to prevent consumer harm. This global regulatory shift involves cooperation with international partners to disrupt offshore entities and remove non-compliant content from social platforms.
