The UK’s Financial Conduct Authority (FCA) is intensely enforcing its new crypto advertising rules, which took effect in October 2023. These rules mandate that any firm promoting crypto assets to UK consumers must be FCA-authorized or registered.
Key Actions and Enforcement
- Massive Warnings: The FCA has issued hundreds of warnings to overseas cryptocurrency exchanges for unlawfully promoting services to UK consumers. Since October 2023, the regulator has published 221 public alerts under the new regime.
- Criminal Offenses: Unauthorized promotions are now considered criminal offenses, punishable by fines or up to two years in prison for corporate officers.
- Public and Private Action: The FCA maintains a public Warning List and is actively collaborating with social media companies, app stores, and payment firms to block or remove illegal ads.
- HTX Lawsuit: In a high-profile move, the FCA filed a High Court lawsuit against the Justin Sun-backed exchange HTX (formerly Huobi) on October 22, accusing it of illegally promoting services while unauthorized.
- The Persistence Problem: Despite the warnings, analysts note that a significant number of illegal promotions—roughly half of those flagged between Oct. 2023 and Oct. 2024—remain accessible online, prompting the FCA to pressure platforms to expedite their removal.
Strict Standards for Legal Promotions
Legal crypto adverts must adhere to the same standards as other high-risk investments. They must be “clear, fair and not misleading,” feature prominent risk warnings, and are banned from using marketing incentives such as cash bonuses or referral rewards.
Balancing Regulation with Innovation
The crackdown on illegal advertising is part of a two-pronged strategy to both protect consumers and encourage a responsible crypto industry in the UK:
- Lifting the ETN Ban: On October 8, 2025, the FCA lifted its four-year ban on retail crypto Exchange-Traded Notes (ETNs), allowing UK exchanges to offer Bitcoin and Ether ETNs to customers.
- Advancing Tokenization: The FCA is also promoting innovation by publishing consultations and a “roadmap” to advance fund tokenization in asset management.
These measures are intended to help the UK “remain competitive” with other crypto-friendly nations.
