The UK government added crypto exchange HTX to its Russia sanctions list on May 26, 2026, accusing it of providing financial services linked to Russia's sanctions evasion network - a designation that triggered immediate compliance warnings from Binance, OKX, Bybit, and Bitget the following day.
The UK Foreign, Commonwealth & Development Office named HTX as part of an 18-entity package targeting what officials described as Russia's "illicit financial infrastructure used to move funds, procure goods, and sustain its war" in Ukraine. The designation covers Huobi Global S.A., the registered operator of the HTX exchange.
British authorities said they had "reasonable grounds to suspect" HTX provided services to two sanctioned entities: Garantex, a Russian crypto exchange that rebranded as Grinex before halting operations in April after a $13 million hack, and A7 LLC, the issuer of the ruble-pegged A7A5 stablecoin. The A7 network is a Kremlin-backed system the Foreign Office says claimed to have moved more than $90 billion last year - equivalent to roughly half of Russia's annual military expenditure. UK officials estimated the network channeled over $1.5 billion back into Russia using a Kyrgyz bank and a major global cryptocurrency exchange.
The designation carries legal force. For the first time, the UK applied Regulation 17A of its Russia sanctions regime to crypto exchanges - a tool previously reserved for designated banks. Per blockchain analytics firm Elliptic, UK virtual asset service providers are now legally required to freeze funds connected to the designated entities, terminate correspondent relationships with them, and trace transactions across multiple blockchain "hops" - meaning compliance checks extend beyond direct counterparties to any wallet or exchange appearing anywhere in a transaction chain.
The industry response was immediate. Binance said transactions involving HTX "may be subject to additional compliance review." OKX warned users who previously engaged in arbitrage between OKX and HTX that continuing such transfers could trigger account scrutiny. Bybit told users to "avoid using HTX-related addresses" when interacting with its platform and flagged that deposits or withdrawals involving HTX-linked addresses face added AML checks. Bitget updated its sanctions screening systems and warned that transactions tied to sanctioned entities or linked addresses could face rejection, restrictions, or account termination.
HTX rejected the allegations. "To clarify, the listed entity Huobi Global S.A. is distinct from the online HTX exchange," the company said in a statement cited by CoinDesk. "While Huobi Global S.A. will work with relevant UK authorities to understand the basis for the action and to address any concerns promptly, the designation does not and should not have any impact on the online HTX exchange." The company also said it refused a listing application for the A7A5 ruble stablecoin.
The HTX designation sits within a broader UK crackdown. Today's package covers 18 designations in total, including Rapira Group LLC, Aifory LLC, Arvix LLC, Bitpapa IC FZC LLC, and three Georgian companies running Russia-focused exchanges. UK officials also sanctioned several individuals accused of sanctions evasion activity, including Sergey Mendeleev, Igor Gorin, Irina Akopyan, and Israeli national Liran Cohen. Foreign Secretary Yvette Cooper called the measures a direct response to the Kremlin's turn to "dark networks and shadow financial systems" as existing sanctions tighten.
HTX reported approximately $3.3 trillion in trading volume in 2025, making it one of the largest crypto exchanges in the world and the highest-profile exchange caught in a Western sanctions action to date. Elliptic noted that other regulators are likely to watch closely as Britain tests applying traditional financial sanctions rules to digital asset markets.
