UK imposes 38 crypto sanctions on A7 network and Russian evasion

On May 26, 2026, the UK struck a heavy blow to the crypto ecosystem: 38 unprecedented sanctions designations target cryptocurrency exchanges for the first time, accused of actively supporting Russia’s war effort through the A7 network and its ruble-pegged A7A5 stablecoin.

An unprecedented sanctions package for the crypto sector

On May 26, 2026, the UK Foreign Office announced a sanctions package comprising 38 designations, the largest ever deployed by London against the digital asset sector. Three cryptocurrency exchanges sit at the core of the package.

Xeltox Enterprises, incorporated in Canada and operating under the trade names Cryptomus, Heleket and Certa Payments, is targeted alongside TokenSpot, based in Kyrgyzstan. The UK government also sanctioned payment service providers, including Processing KG (operating VexPay), Tsunami Payments, and Ulan Bukabaev, director of Processing KG.

One of the most striking targets is HTX (formerly Huobi Global S.A.), one of the world’s largest exchanges with $3.3 trillion in trading volume in 2025. HTX is suspected of providing services to the A7 network and to Garantex, already under sanctions. Other designated platforms include Rapira Group LLC, Nueva Cryptologia SAS de CV (ABCEX), Aifory Pro (a Russian-speaking cash-to-crypto conversion platform), Arvix LLC (suspected ties to Garantex and Grinex) and Bitpapa (a UAE-based peer-to-peer exchange already sanctioned by the US in March 2024).

The A7 network and the A7A5 stablecoin at the core

The structural backbone of this package lies in the A7 network. According to UK authorities, two of the targeted firms had processed or facilitated transactions involving this Kremlin-backed network, which operates the A7A5 stablecoin, pegged to the ruble. London describes A7 as a system designed to circumvent Western sanctions, finance military procurement and channel proceeds from oil sales to fuel Russia’s war effort.

According to figures cited by the UK government, the A7 network reportedly transferred more than $90 billion over the past year, roughly half of Russia’s annual military spending. OJSC Virtual Asset Issuer (USDKG), issuer of the gold-backed, USD-indexed USDKG stablecoin, was also designated for engaging in economic activity of significant importance to the Russian government. Alistera Limited was designated for its role in supporting the A7 network.

“If the Kremlin thinks it can evade our sanctions by hiding behind crypto networks and parallel financial systems, it is sorely mistaken.”

The EU followed suit in July with its twenty-first sanctions package against Russia, targeting 14 cryptocurrency firms and four designations tied to the cross-border A7 network. Three Georgian firms operating Russia-focused exchanges and seeking to evade sanctions were also targeted.

First application of Regulation 17A to crypto exchanges

For the first time, the UK has applied Regulation 17A of the Russia (Sanctions) (EU Exit) Regulations 2019 to cryptocurrency exchanges. Historically used against designated banks in the wake of Russia’s invasion of Ukraine, the regulation imposes extended restrictions on correspondent banking relationships and payment processing.

Regulation 17A prohibits UK financial institutions from establishing or maintaining correspondent banking relationships with designated persons, or with any UK or foreign institution owned or controlled by them. For UK virtual asset service providers (VASPs), this means relationships with designated platforms — for liquidity, settlement or any other purpose — must be severed.

The payment processing ban applies to the entire chain. UK firms are prohibited from processing any payment, regardless of currency, where funds have been previously processed by, or are destined for, an entity designated under Regulation 17A. The text goes further by capturing indirect exposure: the prohibition applies even if the originating and beneficiary account holders are not themselves sanctioned. If a designated exchange appears anywhere in the payment chain — as remitting institution, intermediary or ultimate beneficiary — the transaction is prohibited.

Operational consequences for UK VASPs

For UK virtual asset providers, compliance obligations are now particularly demanding. Any funds held by a UK provider on behalf of a designated entity must be frozen. Direct name screening is no longer sufficient: providers must trace inbound deposits through prior steps and assess the expected path of outbound transfers to identify exposure to designated platforms.

Suspicious activity reports must be filed with the National Crime Agency (NCA), while notifications to the Office of Financial Sanctions Implementation (OFSI) must be made within prescribed reporting deadlines. This “payment chain” approach redefines the due diligence required on on-chain corridors involving stablecoins.

Russian economic context and methodological caveats

In its statement, the UK government noted that Russia has cut its 2026 economic growth forecast from 1.3% to 0.4%, while halving its 2027 projections. The 18 designations package targets the illicit financial infrastructure used by Moscow to move funds, source goods and sustain its war economy.

Beyond crypto actors, the package also covers Russian oil producers (Zaribezjmeft, INK Capita), 12 shadow fleet tankers, and suppliers of machinery, electronics and other products used in the production of missiles and drones. Since the start of the conflict, the UK has sanctioned more than 3,300 individuals, entities and vessels. London estimates that Russia’s war economy has lost more than $450 billion as a result of international sanctions, equivalent to two years of war financing.

However, some blockchain analytics firms have disputed the real scope of the A7A5 stablecoin’s reported activity, raising questions about the reliability of the UK government’s figures for the A7 network’s transaction volumes. This methodological uncertainty calls for caution in interpreting public data.

Conclusion: a precedent for global crypto regulation

This UK sanctions package marks a major regulatory precedent: for the first time, Regulation 17A applies to cryptocurrency exchanges, extending the scope of financial restrictions into a venue long considered opaque. UK virtual asset providers must now run exhaustive screening of their on-chain payment corridors and meet enhanced reporting obligations.

In the short term, expect intensified Western pressure on crypto corridors used by Russia, particularly via fiat-pegged stablecoins. The convergence between London and Brussels on targeting the A7 network lays the groundwork for stronger transatlantic coordination. It remains to be seen how emerging jurisdictions (Kyrgyzstan, the UAE, Georgia) respond to these designations — and whether the publicly announced volume figures will withstand independent audit.
