UK Targets HTX Affiliate as Report Flags $7.6B Suspicious Crypto Flows

The UK sanctioned 18 entities connected to the “A7” network, while blockchain analytics firms Global Ledger and TRM Labs reported billions of dollars in Russia-linked crypto flows involving HTX. The sanctions include asset freezes and restrictions on British firms processing related transactions.

HTX Denies Russia Sanctions Claims

HTX pushed back against allegations tied to a new UK sanctions package after the British government accused affiliate Huobi Global S.A. of helping facilitate billions of dollars in transactions linked to Russia’s shadow financial network. The dispute started after the UK Foreign, Commonwealth and Development Office (FCDO) announced sanctions against 18 entities allegedly connected to the “A7” network, which authorities claim has been used to help Russia evade financial restrictions imposed following the war in Ukraine.

According to the UK government, there are “reasonable grounds to suspect” that Huobi Global S.A. provided financial services to A7 Limited Liability Company and Garantex Europe OU, both of which were included in the sanctions package. The move is one of the biggest enforcement actions yet targeting a cryptocurrency-related entity in connection with Russia sanctions evasion.

HTX quickly responded by distancing itself from the sanctioned entity. In a statement that was shared on X, the exchange argued that its operating platform functions independently from Huobi Global S.A. and insisted that user assets and exchange operations remain unaffected by the UK action. HTX also stated that it plans to engage directly with British authorities regarding the designation.

UK Foreign Secretary Yvette Cooper framed the sanctions package as part of a crackdown on illicit finance and crypto networks allegedly exploited by Russia. Cooper warned that attempts to use digital asset systems to bypass international sanctions would not succeed, and added that the UK government intends to continue targeting financial infrastructure that enables sanctions evasion.

The case gained even more attention after blockchain analytics firm Global Ledger released findings indicating that more than $7.6 billion in Russia-linked cryptocurrency flows moved through HTX over multiple years. The report tracked transactions involving Bitcoin, Ethereum, and Tether on the Tron blockchain. Global Ledger’s investigators used internal risk scoring systems to identify transactions associated with high-risk activity, including sanctioned entities, darknet markets, and other illicit operations.

The analytics firm also claimed to identify links involving several controversial organizations and networks beyond Russia. These reportedly included exposure to Huione Group, Iranian exchange Nobitex, Hezbollah-linked addresses, and North Korea’s Lazarus Group. The findings raised important concerns about HTX’s compliance systems and the challenges exchanges face in policing large-scale global transaction flows.

Separate research from TRM Labs reportedly identified approximately $4.9 billion in direct on-chain transfers between HTX and UK-designated entities since 2021. Meanwhile, British authorities claimed that the wider A7 network moved more than $90 billion last year.

The sanctions introduce strict restrictions for British firms, including asset freezes and prohibitions on processing transactions linked to the designated entity. The development is considered a major escalation in how Western governments approach crypto enforcement, particularly as regulators increasingly apply banking-style compliance standards to major digital asset platforms.
