On May 26, 2026, the United Kingdom imposed a significant new sanctions package targeting 18 cryptocurrency-related entities and individuals deeply embedded in networks that facilitate Russia’s circumvention of international trade restrictions. This action, issued by the Foreign, Commonwealth and Development Office (FCDO), highlights the role of digital assets in sustaining Russia’s economy amid ongoing geopolitical tensions. The designations focus on the so-called A7 network, which has reportedly funneled tens of billions in value to support Russian operations.
At the center of the measures stands HTX (formerly Huobi), a major global exchange that recorded $3.3 trillion in trading volume in 2025.
UK authorities suspect it of routing over $1.5 billion toward Russian-linked activities, often through connections to previously restricted platforms like Garantex and Grinex.
Blockchain intelligence firms have documented even larger exposure.
TRM Labs reports that Huobi sent more than $4.9 billion in direct on-chain transactions to sanctioned and A7-affiliated entities since 2021, with flows accelerating sharply after Garantex’s disruption in March 2025.
Specifically, transfers to successor platforms surged tenfold in the following period, underscoring how liquidity quickly shifted to new channels.
The A7 network, built around the ruble-pegged A7A5 stablecoin issued in Kyrgyzstan, has processed enormous volumes—reaching $93 billion in its first year according to earlier analyses.
This infrastructure, along with associated exchanges and payment providers, has served as a critical conduit for converting fiat and stablecoins while bypassing traditional banking controls.
Chainalysis previously tracked how A7A5 traded heavily on Russia-tied venues, with much of the activity migrating after enforcement actions against predecessors.
The new sanctions target not only high-profile exchanges but also supporting firms like EXMO Exchange, Rapira Group, Aifory Pro, Arvix, Alistera Limited, Bitpapa, and the issuer of the gold-backed USDKG stablecoin, among others. Several individuals linked to these operations were also designated.
Elliptic notes that this package marks the first application of Regulation 17A—previously used mainly against banks—to cryptocurrency exchanges.
This regulation prohibits UK financial institutions from maintaining correspondent relationships or processing payments involving designated entities, even indirectly.
Any transaction where a sanctioned exchange appears anywhere in the chain becomes restricted, extending obligations beyond simple name screening to full transaction tracing.
Combined with standard asset freeze rules, UK virtual asset service providers (VASPs) must now freeze connected funds and scrutinize multi-hop flows. This raises the compliance bar substantially, demanding advanced on-chain visibility.
TRM Labs data further illustrates the post-Garantex pivot: platforms like Rapira and ABCex (Nueva Cryptologia) rapidly absorbed displaced activity, with bilateral flows in the hundreds of millions.
Bitpapa, already sanctioned by the US and Ukraine, now faces its third major regime restriction, signaling increasing multilateral pressure.
These patterns reveal a resilient ecosystem where entities replicate services, share infrastructure, and maintain ruble-to-crypto onramps for Russian users.
For compliance teams, the implications are clear. Static list screening is insufficient; firms need behavioral monitoring, wallet attribution, and the ability to detect successor platforms before formal designations.
UK-regulated entities must immediately freeze assets and report exposures, while global players face heightened reputational and counterparty risks.
This move aligns with broader international efforts, including recent EU measures, to tighten controls on digital asset channels supporting Russia’s activities.
The UK’s latest sanctions demonstrate regulators’ evolving sophistication in addressing crypto-enabled evasion. By targeting liquidity providers and niche facilitators, authorities aim to disrupt the financial plumbing that has allowed billions to flow despite existing restrictions.
