In one of the most aggressive moves any government has taken against a major crypto platform, the United Kingdom sanctioned HTX (formerly Huobi) on Monday for allegedly helping Russia move $1.5 billion through crypto to fund its war in Ukraine.
The sanctions package, announced by the Foreign, Commonwealth & Development Office, targets 18 entities and individuals linked to what UK officials described as Russia’s “illicit financial infrastructure used to move funds, procure goods, and sustain its war.” HTX, listed under its corporate name Huobi Global S.A., was the biggest name on the list.
What makes this unprecedented is the legal tool the UK used. For the first time ever, Britain applied Regulation 17A of its Russia sanctions regime to crypto exchanges. This regulation was previously reserved for sanctioned banks. It bans all UK financial institutions and crypto service providers from maintaining correspondent relationships with designated entities, processing payments tied to them, or facilitating any transactions that pass through them.
In plain terms, the UK is now treating HTX exactly the same way it treats sanctioned Russian banks. That’s a first for any crypto exchange anywhere in the world.
What HTX Is Accused Of
The UK government alleges that HTX provided financial services to the A7 network, a sanctioned business group that officials say moved over $90 billion in support of Russia’s war economy. According to Bloomberg’s reporting, HTX is accused of helping move approximately $1.5 billion back to the Kremlin through its platform.
The government said there were “reasonable grounds to suspect” that Huobi Global S.A. was involved in providing financial services, making available funds, and supporting the Russian government by facilitating transactions for A7 Limited Liability Company, which operates in a sector of strategic significance to the Russian government.
The framing is important. The UK isn’t treating HTX as a peripheral player that accidentally processed some sanctioned transactions. It’s positioning the exchange as core infrastructure in Russia’s sanctions-evasion architecture, a willing participant in a system designed to keep money flowing to a regime under international isolation.
Foreign Secretary Yvette Cooper left no ambiguity in her statement. She said the UK is actively tracking down “the infrastructure that underpins its war economy” and that there will be “no safe havens” for platforms hiding behind crypto networks.
HTX Was Already in Trouble in the UK
Monday’s sanctions didn’t come out of nowhere. HTX had been on the UK authorities’ radar for months.
In February 2026, the Financial Conduct Authority launched legal proceedings against HTX for allegedly publishing unlawful financial promotions across its website, TikTok, X, Facebook, Instagram, and YouTube. The FCA accused the exchange of targeting UK consumers with marketing materials that didn’t comply with British financial promotion rules.
That case was already significant on its own. But it now looks like the opening salvo in a much broader enforcement campaign. The FCA action established that HTX was actively marketing to UK users. The sanctions announcement establishes that the exchange was allegedly facilitating Russian sanctions evasion. Together, they paint a picture of an exchange operating in direct defiance of UK law on multiple fronts.
HTX has not publicly responded to the sanctions. Justin Sun, the platform’s most prominent figure and a member of the global advisory board, has not commented. The exchange processed $3.3 trillion in trading volume in 2025, making it one of the largest crypto exchanges by trading volume.
The Other 17 Entities on the List
HTX grabbed the headlines, but the sanctions package goes much deeper. The UK designated 17 additional entities and individuals tied to Russia’s crypto-enabled financial networks.
Among them are Exmo Exchange, Rapira Group LLC, Bitpapa, Aifory Pro, Arvix LLC, Nueva Cryptologia SAS de CV, and OJSC Virtual Asset Issuer. The Eurasian Savings Bank was also sanctioned. Several of these entities are linked to the Garantex network, the Russian crypto exchange that was sanctioned by the US Treasury in 2022 and seized by authorities in 2025.
Blockchain analytics firm Elliptic, which works with UK authorities on sanctions compliance, confirmed that the designations cover a wide array of crypto exchanges, banks, individuals, and corporate entities linked to Russia’s sanctions evasion. Elliptic described the package as one of the UK’s most expansive crypto-focused sanctions actions to date.
The breadth of the designations signals that the UK isn’t just going after individual bad actors. It’s systematically dismantling the network of platforms and intermediaries that Russia has been using to move money around Western restrictions. Each entity on the list represents a node in that network. Cutting them all off simultaneously is designed to collapse the infrastructure rather than just plug individual leaks.
What Regulation 17A Means for the Crypto Industry
The application of Regulation 17A to crypto exchanges is a legal milestone with ripple effects far beyond HTX.
Under Regulation 17A, UK financial firms and virtual asset service providers cannot process payments to, from, or through designated entities. Crucially, this includes indirect exposure. If a transaction passes through HTX at any point in the payment chain, even if the UK firm is not directly transacting with HTX, it can trigger compliance obligations.
That indirect exposure provision is what makes this so significant for the broader crypto industry. Every UK-based exchange, wallet provider, and payment processor now needs to screen for HTX-linked transactions across the entire blockchain. If a payment touches an HTX wallet at any hop in the chain, the UK firm handling it could face penalties.
For compliance teams at UK crypto companies, the workload just increased substantially. They need to map HTX’s on-chain footprint, identify wallets associated with the exchange, and build screening rules that catch both direct and indirect exposure. That’s a non-trivial technical challenge given the pseudonymous nature of blockchain transactions.
Elliptic said its tools are already updated to flag HTX-linked transactions for UK clients. But smaller firms without access to enterprise-grade analytics may struggle to meet the new compliance requirements, potentially creating liability risks they don’t yet fully understand.
The Justin Sun Question
There’s an elephant in the room that every story about HTX has to address. Justin Sun, the founder of Tron and one of the most visible figures in crypto, serves as a global advisory board member at HTX.
Sun is currently entangled in a separate legal dispute with Trump’s World Liberty Financial over a token deal gone sour. He’s also facing long-standing SEC charges in the US related to the offer and sale of unregistered securities and alleged market manipulation.
The UK sanctions don’t name Sun personally. But his close association with HTX means the designation effectively limits his ability to conduct business with any UK-connected financial institution. Whether the sanctions lead to further personal scrutiny of Sun remains to be seen, but the pressure on his business operations has just increased significantly.
What This Means for the Global Crypto Landscape
The UK’s decision to apply banking-style sanctions to a crypto exchange sends a clear message to the entire industry: crypto platforms are not exempt from the same rules that govern traditional financial institutions.
For years, some exchanges operated under the assumption that their decentralized or offshore structures placed them beyond the reach of Western sanctions regimes. The HTX designation proves that assumption wrong. If a UK or US citizen, bank, or business processes a transaction that touches a designated crypto exchange, they face the same legal consequences as if they’d done business with a sanctioned Russian bank.
The timing is also notable. It comes during the same week that the CFTC is under fire for allegedly going too easy on crypto firms with political connections, and the same month that Congress is debating the CLARITY Act’s approach to crypto regulation. The UK’s aggressive enforcement provides a counterpoint to the lighter-touch approach that parts of the US regulatory establishment have been pursuing.
For legitimate crypto exchanges, the HTX sanctions reinforce the importance of robust compliance programs. For users, it’s a reminder to check whether the platforms they use have clear regulatory standing in the jurisdictions that matter. And for the industry as a whole, it’s further evidence that the era of crypto operating in a regulatory grey zone is rapidly coming to an end.
