U.K. sanctions 18 crypto entities and targets a $93B stablecoin network used to evade Russia restrictions. Exchanges must comply immediately.

The U.K. government announced a sanctions package on May 26 that targets 18 cryptocurrency exchanges, payment providers, corporate entities, and individuals tied to Russia-facing sanctions-evasion networks. The measures take effect immediately. Secretary of State for Foreign, Commonwealth and Development Affairs Yvette Cooper said:
“If the Kremlin thinks it can evade our sanctions by hiding behind crypto networks and shadow financial systems, it is gravely mistaken.”
The package is not a blanket ban on crypto activity. It designates specific platforms, stablecoin infrastructure, and the A7 network, a Kremlin-linked channel that the government says moves money through Kyrgyzstan financial routes, finances military procurement, and processes oil-sale proceeds. For U.K. virtual asset service providers (VASPs), the immediate obligation is to block transactions and freeze assets tied to the named entities – a compliance burden that expands under a regulatory tool applied to crypto exchanges for the first time.
The sanctions target the A7 network and its associated stablecoin infrastructure. Chainalysis reported that A7A5, a ruble-backed stablecoin issued in Kyrgyzstan, recorded $93 billion in trading volume during its first year. The firm linked A7A5 to the OJSC Virtual Asset Issuer, which also issues USDKG, another stablecoin named in the sanctions. Elliptic identified Grinex, described as the successor to Garantex, as involved in A7A5 trading.
The A7-related designations include:
Officials described A7 as a Kremlin-backed network used to channel funds and bypass existing restrictions.
For any U.K.-registered exchange or broker, the presence of A7-linked entities in transaction data now triggers mandatory reporting and freezing. Elliptic called the action “one of its most expansive cryptoasset-focused sanctions packages to date.” The firm noted that the U.K. applied Regulation 17A to cryptoasset exchanges for the first time, dramatically expanding obligations for U.K. VASPs. Chainalysis said the rule targets core financial payment channels by cutting off correspondent banking relationships and restricting transfers involving designated entities.
Regulation 17A of the Sanctions and Anti-Money Laundering Act had previously applied to traditional financial institutions. Its extension to crypto exchanges means that U.K.-based VASPs must now conduct enhanced due diligence on any transaction that touches a designated entity or network. The U.K. government’s statement explicitly says the sanctions cover “cryptocurrency exchanges and the ‘A7 network’.”
For a London-based broker or fund, this introduces execution risk: any routing through an exchange that transacts with these entities could trigger a compliance event. The Monetary Authority of Singapore has also reiterated that crypto exchanges need to conform to restrictions on Russian users, signaling a broader regulatory alignment beyond the U.K.
The list includes Huobi Global, a major exchange with significant spot and derivative volume. Other named platforms – Bitpapa, EXMO, Rapira – operate across the CIS region and the Middle East. For any of these exchanges, the immediate risk is that U.K. banking and payment partners will sever relationships, cutting off fiat on-ramps.
Chainalysis noted that the sanctions target “core financial payment channels,” meaning the disruption is not limited to the named exchanges but extends to any platform that relies on those payment rails.
The U.K. package shares a geopolitical context with earlier events that triggered broad market reactions, such as the $300M crypto liquidation after Iran strikes. Traders should watch for similar volatility if regulators in other major financial hubs announce parallel sanctions.
The U.K. sanctions package is a concrete risk event for any trader or broker with exposure to Russia-linked crypto channels. The immediate action is to verify that no counterparty on the designated list processes trades, deposits, or withdrawals. The longer-term shift is the expansion of Regulation 17A into crypto – a regulatory tightening likely to spread to other jurisdictions. For traders, the practical step is to review compliance notices from any exchange used for cross-border settlements and stablecoin transactions. The $93 billion A7A5 volume shows that this channel was material; its disruption will create winners and losers in competing liquidity networks.
