UK Targets Crypto in Escalating Sanctions Against Russia
For three years, Western nations have worked to build an airtight financial blockade around Russia, severing its banks from SWIFT and freezing sovereign reserves. Yet, according to British authorities, Russia has spent much of that same period engineering an alternative financial system, built on digital assets, designed to circumvent these restrictions entirely. This paradox has led to a significant shift in the strategy of economic warfare.
“This move signifies a profound shift in how economic warfare is waged,” commented a senior analyst on international finance. “Regulators now perceive certain crypto entities as critical financial infrastructure, demanding the same level of scrutiny and enforcement previously reserved for traditional banks.”
Britain’s Landmark Regulatory Move
On May 26, the UK’s Foreign, Commonwealth & Development Office sanctioned 18 entities and individuals. Among them were Huobi (HTX), a Justin Sun-advised exchange that processed $3.3 trillion in trading volume in 2025, and a Kyrgyzstan-linked stablecoin issuer. These entities are accused of helping Russia evade Western restrictions.
What distinguishes this package of sanctions is the legal instrument Britain reached for. For the first time, the UK applied Regulation 17A of its Russia sanctions regime to crypto exchanges. This tool was previously reserved only for sanctioned banks, requiring all financial firms in the UK to freeze funds and sever correspondent relationships with designated entities. Extending that rule from banks to crypto exchanges shows that regulators now see parts of the crypto industry as infrastructure equivalent to formal financial institutions.
Unmasking the A7 Network: A Kremlin-Backed Financial System
The primary target of the new set of sanctions is the A7 network — a Kremlin-backed system the government says was built to bypass Western sanctions, finance military procurement, and process revenue from Russian oil exports. A7 was founded in October 2024, and the UK has connected its ownership structure to the Russian government.
- The majority stake belongs to Ilan Shor, an Israeli-Moldovan oligarch convicted in 2017 for his role in the theft of $1 billion from three Moldovan banks, who later received Russian citizenship.
- The minority stake belongs to Promsvyazbank, a Russian state-owned bank sanctioned in 2022 for financing Russia’s military-industrial complex.
The Kremlin’s blessing was explicit: when A7 opened a physical branch in Vladivostok in September 2025, Vladimir Putin attended the virtual ribbon-cutting ceremony. A7 has also expanded into Lagos and Harare, opening offices in Nigeria and Zimbabwe as part of a push into jurisdictions less exposed to Western regulatory pressure.
The scale of the operation has certainly worried the UK. The UK government says the A7 network claimed to have moved more than $90 billion in 2025 alone — a figure it describes as roughly equivalent to half of Russia’s annual military spending.
A7A5: Russia’s Sanctions-Resistant Stablecoin
After being faced with sanctions in 2022, Russian businesses turned heavily to Tether (USDT) for international transactions. This dollar-pegged stablecoin could move across borders quickly and without requiring correspondent banking relationships that Western sanctions had effectively closed off. USDT offered Russian firms the stability of the dollar and the frictionless transferability of crypto, a combination that served them well until US authorities seized Garantex‘s USDT holdings in March 2025 and Tether froze wallets linked to the sanctioned exchange. This exposed the fundamental liability of any token subject to centralized freeze controls.
A7A5 is essentially the answer to that vulnerability. Issued by a Kyrgyz entity called Old Vector LLC and backed by ruble deposits held at Promsvyazbank, it’s designed to work like USDT while resisting the specific pressure point that disabled Garantex. After Garantex was shut down, its customers’ funds migrated to a successor exchange called Grinex, with A7A5 serving as the bridge that allowed them to move their balances without touching the global banking system.
The Broader Landscape of Crypto Evasion
The numbers running through these systems reflect a scale that the UK now sees as a systemic concern. According to Chainalysis‘s 2026 Crypto Crime Report, sanctions evasion via crypto surged 694% in 2025, with sanctioned entities receiving roughly $104 billion through digital asset channels. Stablecoins drove most of that volume, accounting for 84% of all illicit crypto transaction value.
Russia has also been leveraging its subsidized energy sector to capture roughly 16% of global Bitcoin mining capacity, effectively producing new coins with no on-chain link to any sanctioned wallet or entity. This serves as a separate but complementary layer of financial insulation. TRM Labs traced $4.9 billion in direct transfers from HTX to UK-designated entities since 2021, including $1.95 billion to the already-sanctioned Garantex in 2022 and $838 million to A7 in 2025 alone. HTX has since disputed the accusation, arguing in a public statement that it applies only to Huobi Global S.A. as a separate legal entity and that its exchange operations and user funds remain unaffected.
“The irony of these sanctions is that while they inflict economic pain, they simultaneously accelerate the development of parallel financial systems designed to operate outside Western influence,” noted a geopolitical strategist. “This infrastructure, once built, will likely persist long after current conflicts subside, reshaping global finance.”
FAQs on Russia’s Crypto Sanctions Evasion
-
What is the A7 network?
The A7 network is a Kremlin-backed financial system established to circumvent Western sanctions, fund military procurement, and process revenue from Russian oil exports. It was founded in October 2024 and is alleged to have moved over $90 billion in 2025.
-
Why is the UK targeting crypto exchanges with banking-grade tools?
The UK has applied Regulation 17A, previously reserved for banks, to crypto exchanges like HTX for the first time. This reflects a recognition that parts of the crypto industry are functioning as critical financial infrastructure used for large-scale sanctions evasion, necessitating similar regulatory measures.
-
How has Russia used stablecoins for evasion?
Russia initially leveraged USDT for international transactions due to its stability and frictionless transferability. However, after USDT linked to Garantex was frozen, Russia shifted to its own ruble-backed stablecoin, A7A5, designed to be resistant to centralized freezes, enabling continued cross-border payments for sanctioned entities.
-
What is A7A5?
A7A5 is a ruble-backed stablecoin issued by the Kyrgyz entity Old Vector LLC and backed by deposits at Promsvyazbank. It serves as the primary settlement rail for the A7 network, allowing sanctioned Russian businesses to conduct cross-border trade without relying on the traditional banking system.
