HTX disputes UK sanctions

Highlights

UK sanctioned Huobi Global S.A., behind HTX, on May 26 for allegedly providing financial services and resources to Russian entities involved in the war economy.
Blockchain data from Global Ledger shows HTX processed $21.06 billion in high-risk crypto flows since 2021, including $7.64 billion linked to Russian and darknet entities.
HTX maintains its exchange and user funds are unaffected while the FCA started High Court proceedings in October 2025 for allegedly breaching UK crypto promotion rules.

UK sanctions action and HTX response

As reported by the UK government, the latest Russia sanctions package announced on May 26 includes Huobi Global S.A., the Panamanian company behind the HTX platform, over allegations it provided financial services and economic resources to already restricted entities linked to Moscow’s war economy.

The package covers 18 designations tied to what British authorities describe as crypto and illicit finance networks used by Russia, including the Kremlin-backed A7 shadow system. The measures include asset freezes and bans on the provision of financial services, and the Foreign Office says the targeted infrastructure includes a Kyrgyz bank and a major global cryptocurrency exchange suspected of funnelling more than $1.5 billion back into Russia’s hands.

HTX says the designation applies only to Huobi Global as a separate legal entity and maintains that its online exchange and user funds remain unaffected. In a post on X on Tuesday, the exchange says operations continue normally and stresses its commitment to compliance and cooperation with law enforcement agencies.

The pressure on the platform is widening in the UK. The Financial Conduct Authority began High Court proceedings in October 2025 against Huobi Global and individuals said to control it, alleging illegal promotion of crypto trading services to UK consumers in breach of the country’s financial promotion rules.

Blockchain data sharpens sector compliance concerns

New analysis from Global Ledger says HTX processed about $21.06 billion in high-risk crypto flows between 2021 and May 2026. Of that amount, at least $7.64 billion is linked to Russian high-risk entities and darknet markets, including Garantex, Grinex, A7A5 and the defunct Hydra marketplace, as well as Kraken darknet and Mega darknet.

The report also identifies exposure involving Huione Group, Nobitex, Hezbollah and North Korea-linked Lazarus, suggesting the exchange’s risk profile extends beyond Russia-related activity. Bloomberg, citing UK officials on Tuesday, says HTX helped move about $1.5 billion back to Russia, a figure that is lower than Global Ledger’s broader estimate based on multi-year onchain tracing of Bitcoin, Ether and Tether on Tron.

The dispute highlights a broader compliance challenge for the crypto sector as Western governments try to curb sanctions evasion through major centralized exchanges. Global Ledger says sanctioned Russian networks continue to access liquidity despite mounting restrictions, underlining the growing regulatory and reputational risks facing trading platforms with cross-border exposure.

In our earlier article on the UK’s sanctions targeting Russia-linked crypto payment routes, we described how British authorities aimed to disrupt channels used to bypass financial restrictions tied to the war in Ukraine. We noted that the measures included Huobi-linked HTX alongside smaller regional platforms and the A7 payments network, underscoring regulators’ focus on stablecoins and shadow infrastructure that can keep cross-border flows moving under sanctions pressure.
