FCA Sues HTX in Escalating Crackdown on Unregistered Crypto Exchanges

The UK's Financial Conduct Authority (FCA) has filed a lawsuit against offshore cryptocurrency exchange HTX, marking one of its strongest enforcement actions to date in the sector's ongoing regulatory overhaul. The move underscores the regulator's intent to clamp down on firms operating without proper registration while still promoting services to UK users.

In an announcement on Tuesday, the FCA confirmed legal proceedings against HTX—formerly known as Huobi—citing violations of its financial promotions regime. "We have seen crypto firms react positively to our financial promotions rules and regulations; however, where we still see poor practices, we will not hesitate to take action," an FCA spokesperson said.

The lawsuit follows months of intensified scrutiny. In October, the regulator issued warnings to dozens of platforms, including Elite Bit Markets, Nexure Gainbit, Plux Crypto, and HTX, for allegedly targeting UK clients without authorization under anti-money-laundering laws.

The FCA's stance highlights a broader regulatory balancing act as London seeks to strengthen consumer protections while reasserting itself as a hub for digital finance. The UK recently lifted its ban on crypto exchange-traded notes (ETNs) and outlined a framework for tokenized funds—moves aimed at attracting institutional investment under tighter compliance standards.

Under the UK's classification system, most crypto products fall into the "Restricted Mass Market Investments" category, requiring firms to include clear risk warnings and avoid promotional incentives directed at retail investors. Companies found to breach these rules may face fines, criminal charges, or imprisonment.

Despite stricter oversight, enforcement challenges persist. The Financial Times reported that nearly half of the crypto advertisements flagged by the FCA between late 2023 and 2024 remained active months after official warnings.

The lawsuit against HTX signals a shift from warnings to direct legal action. Whether it ushers in broader compliance or prompts more exchanges to move offshore will test how far the FCA is willing to go in reshaping the UK's crypto landscape.
