SKN | UK Regulator Takes High Court Action Against HTX Over Alleged Illegal Crypto Promotions

The United Kingdom’s financial watchdog has stepped up its enforcement campaign against offshore crypto platforms, launching High Court proceedings against cryptocurrency exchange HTX over alleged illegal marketing to British consumers. The case marks the first time the regulator has taken court action against a crypto firm for breaching the UK’s financial promotions rules, signaling a more aggressive phase of oversight.

In a statement published Tuesday, the Financial Conduct Authority (FCA) said it began proceedings in October 2025 against HTX and several related, unidentified persons in the Chancery Division of the High Court. The regulator confirmed it has now received permission to serve the case outside the UK and through alternative means, reflecting the fact that HTX is incorporated in Panama.

Financial Promotions Regime Under the Spotlight

The legal action is being brought under the FCA’s Financial Promotions Regime, which came into force in October 2023 and significantly tightened how crypto firms can advertise to UK consumers. The rules require crypto promotions to be clear, fair, and not misleading, and generally restrict marketing to firms that are authorized or whose promotions are approved by an authorized entity.

According to the FCA, HTX allegedly continued to promote cryptoasset services to UK users despite warnings that its marketing activity breached these requirements. The regulator said that advertising crypto products in the UK without complying with the regime is a criminal offense, particularly when promotions are disseminated through mass-market channels such as social media.

Social Media at the Center of the Case

The watchdog said HTX used multiple online platforms to promote its services to British consumers, including TikTok, X, Facebook, Instagram, and YouTube. These promotions allegedly persisted even after the FCA had previously issued warnings to the exchange.

“Firms providing crypto products to UK consumers need to comply with rules which protect consumers from unfair and misleading marketing,” the FCA said in its update. It added that HTX’s continued activity suggested a disregard for the regulatory framework that most firms operating in the UK market are now attempting to follow.

As part of its enforcement push, the FCA has also asked social media companies to block HTX’s accounts for UK-based users. In addition, the regulator requested the removal of HTX’s apps from UK app stores operated by Google and Apple, further limiting the exchange’s ability to reach British customers.

A Warning to the Wider Industry

Steve Smart, the FCA’s joint executive director of enforcement and market oversight, said the case is intended to send a clear signal to the crypto industry. “Our rules are designed to support a sustainable and competitive crypto market in the UK, ensuring that consumers have what they need to make informed decisions,” he said.

“HTX’s conduct stands in stark contrast to the majority of firms working to comply with the FCA’s regime. This is the first time we’ve taken enforcement action against a crypto firm illegally marketing their products to UK consumers,” Smart added, warning that the regulator will continue to act against firms that ignore the rules.

The FCA has also placed HTX on its public Warning List, alerting consumers that they do not benefit from UK regulatory protections if they use the platform. That designation typically serves as a red flag to retail users and can significantly curtail a firm’s ability to attract new customers in the UK.

Broader Implications for Crypto Firms

The action against HTX comes as the UK seeks to position itself as a regulated but open hub for digital assets, balancing innovation with consumer protection. Since the introduction of the Financial Promotions Regime, dozens of crypto firms have either altered their marketing strategies, partnered with authorized firms, or exited the UK market altogether.

For global exchanges, the case highlights the growing risks of targeting UK users without clear regulatory alignment. Even firms incorporated offshore are not beyond the FCA’s reach if they are deemed to be promoting services to British consumers.

HTX did not respond to requests for comment by publication. As the case proceeds, industry observers will be watching closely to see how the courts interpret the scope of the promotions regime — and how far UK authorities are willing to go to enforce it.
