UK Sanctions Huobi and Ruble Stablecoin Issuer in Russia Crypto Crackdown
The United Kingdom on May 26, 2026 sanctioned crypto exchange Huobi and a ruble-pegged stablecoin issuer as part of a sweeping crackdown on cryptocurrency networks allegedly helping Russia evade Western sanctions, marking the first time London has applied its crypto-specific sanctions powers against digital asset exchanges.
The UK’s Foreign, Commonwealth and Development Office designated 18 entities and individuals under the Russia (Sanctions) (EU Exit) Regulations 2019. The package targets exchanges, stablecoin issuers, and key individuals tied to networks the UK says funneled billions in value to sanctioned Russian actors.
UK Russia Sanctions — May 26, 2026

Entities & individuals designated
Includes Huobi Global S.A. (HTX), OJSC Virtual Asset Issuer & A7 network entities
UK Targets Huobi and Ruble Stablecoin Issuer With New Sanctions
HUOBI GLOBAL S.A., the Panama-registered entity operating the HTX exchange, was designated under Category 2 for making available funds and economic resources to Russian financial sector actors. HTX recorded approximately $3.3 trillion in trading volume in 2025, making it one of the world’s largest crypto exchanges at the time of sanctioning.
OJSC “Virtual Asset Issuer,” a Kyrgyzstan-linked entity issuing the gold-backed USDKG stablecoin, was designated under Category 3 for carrying on business of economic significance to the Government of Russia. Other exchanges caught in the package include EXMO Exchange Limited, Bitpapa IC FZC LLC, Arvix LLC, Rapira Group LLC, and Aifory LLC.
Four individuals were also named: Sergey Mendeleev, Igor Olegovich Gorin, Irina Rafaelyevna Akopyan, and Liran Cohen. The designations impose immediate asset freezes and prohibit UK persons from dealing with any of the listed entities.
UK Foreign Office Minister Stephen Doughty framed the action in blunt terms:
“If the Kremlin thinks they can hide their desperate attempts to soften the blow of our sanctions by laundering transactions through dodgy crypto networks, they are sorely mistaken.”
How These Entities Allegedly Helped Russia Evade Western Sanctions
At the center of the UK’s case is the A7 network, a constellation of entities that operated the ruble-backed A7A5 stablecoin. The token, pegged 1:1 to rubles held at Promsvyazbank, a sanctioned Russian defense bank, surpassed $100 billion in cumulative on-chain transactions by January 2026, according to blockchain analytics firm Elliptic.
A7A5 Ruble Stablecoin — Cumulative On-Chain Transactions
$100B+
By January 2026 • 250,000+ transfers • 41,000+ wallets
The A7A5 token reached over 41,000 unique wallet accounts and around 250,000 total transfers before prior sanctions rounds began to bite. Daily transaction volume peaked at $1.5 billion before falling to roughly $500 million following earlier enforcement actions. The network reportedly burned and reissued approximately 80% of its tokens to break transaction traceability after those earlier designations.
A7 network entities designated in this package include Trace Road LLC, LLC Diamond Estate, and OJSC State Brokerage Company. The network is co-owned by Ilan Shor, a convicted fraudster already sanctioned by Western governments for undermining Moldovan elections, tying the crypto infrastructure directly to Russian defense procurement financing through the Promsvyazbank connection.
HTX was linked to the A7 network and to Garantex, a previously sanctioned Russian exchange. According to one unconfirmed report, HTX channeled over $1.5 billion back into Russian hands, though attribution for that figure remains unclear and may refer to the broader A7 network rather than HTX specifically. Justin Sun, HTX’s high-profile backer, was notably not personally designated. Neither HTX nor Sun has publicly responded to the sanctions at the time of writing.
What the UK Action Signals for Crypto Sanctions Enforcement
This package marks the first-ever application of Regulation 17A of the Russia (Sanctions) (EU Exit) Regulations 2019 to cryptoasset exchanges. The regulation extends standard financial sanctions tools, including asset freezes, trust service bans, correspondent banking restrictions, and internet services prohibitions, to crypto platforms. UK-based virtual asset service providers must now freeze funds linked to designated entities and conduct multi-hop blockchain tracing to ensure compliance.
The action coordinates with the EU’s 20th sanctions package from April 2026, which banned transactions with Russian crypto platforms and prohibited the A7A5 and RUBx stablecoins, as well as parallel US measures announced simultaneously. As regulatory frameworks for digital assets evolve globally, this multi-jurisdictional approach signals Western governments are closing the gap on crypto-enabled sanctions evasion.
UK sanctions against Russia now cover over 3,300 individuals and entities since the full-scale invasion of Ukraine, with officials claiming $450 billion in economic losses inflicted on Russia’s wartime economy. The expansion into crypto-specific designations means exchanges and stablecoin projects operating across DeFi ecosystems with Russian user bases face growing compliance risk across all major Western jurisdictions.
For UK financial firms and VASPs, the immediate obligation is clear: cease dealings with designated entities and report any exposure to the Office of Financial Sanctions Implementation (OFSI). Civil and criminal penalties apply for violations. With the global regulatory landscape tightening in 2026, crypto-native sanctions enforcement has moved from theoretical to operational, and exchanges processing billions in daily volume are squarely in regulators’ crosshairs.
