UK watchdog moves to block crypto exchange

TLDR

The UK Financial Conduct Authority is moving to block access to the HTX crypto exchange in Britain over alleged illegal promotions to UK consumers.

1. The FCA has sued HTX and asked app stores and social platforms to block its services in the UK for repeated unlawful marketing.
2. UK users face shrinking access to HTX and a clear signal that unregistered, opaque offshore exchanges carry heightened regulatory and counterparty risk.
3. The outcome of this case and the UKs upcoming full authorization regime could reshape which exchanges can realistically serve UK customers.

Deep Dive

1. FCA Targets HTX Promotions

In February 2026, the FCA said it had asked Google and other app stores, plus social media platforms, to block UK access to crypto exchange HTX.

The regulator had already filed a lawsuit accusing HTX of unlawfully promoting crypto services to UK consumers and placed the exchange on its warning list for unauthorised firms.

The FCA also criticised HTXs opaque organisational structure, saying it could not identify the owners or website operators and that the firm ignored repeated attempts to engage. Officials described this as the first time they have taken this type of enforcement action against a crypto firm for illegal marketing to UK users.

2. Impact On UK Users

HTX has reportedly stopped new UK customers from registering, but existing UK users can still log in, which is one reason the FCA is pushing platforms to cut access.

If app stores and social networks comply, UK users could find HTXs app removed locally and its official accounts harder to reach, increasing operational and withdrawal risk if they rely on this venue.

By contrast, firms that obtain FCA registration, such as Blockchain.com, are expected to meet strict antimoney laundering and promotions standards, giving UK users a clearer regulatory framework and recourse.

3. Signals For Future Policy

This HTX case sits alongside other developments that show how tough the UK environment has become for exchanges. Gemini, one of the first FCA-registered platforms, has decided to exit the UK and EU in part due to regulatory complexity.

The government is working toward a full crypto authorization regime, where UK-facing exchanges will need full FCA licenses, not just AML registration, within specific windows.

Together, these moves suggest a future where only fully authorized, transparent exchanges can serve UK retail at scale, while unregistered offshore venues face geo-blocks, lawsuits, or de facto exclusion from mainstream app and social platforms.

Conclusion

The FCAs move against HTX shows the UK is prepared to enforce its crypto promotion rules aggressively, including by pressuring app stores and social networks to cut access.

For crypto users, the practical takeaway is that regulatory status and transparency now matter more for venue choice in the UK, and future rules are likely to further concentrate activity in fully licensed exchanges.
