EU imposes largest sanctions on Russia in two years: comprehensive ban on crypto platforms, A7A5 stablecoins and digital ruble blacklisted

On April 23, the EU announced its 20th round of sanctions against Russia, the largest in two years. For the first time, it comprehensively prohibits EU residents from interacting with Crypto Asset Service Providers (CASPs) and DeFi platforms within Russia, while simultaneously adding the digital ruble, the RUBx stablecoin, and the Kyrgyzstan-based exchange TengriCoin to the sanctions list. The measures will officially take effect on May 24, 2026, with the core objective of severing Russia's channels for bypassing sanctions via crypto rails—even as the "purpose-built settlement rail" known as A7A5 has reached a cumulative transaction volume of $119.7 billion, growing larger despite the crackdown.

This is the first time Brussels has designated CASP-level engagement as a prohibited activity, rather than targeting individual entities, with an effective date of May 24, 2026. The Council of the EU stated in its declaration on April 23 that the digital ruble (Russia's CBDC) and the RUBx stablecoin will be formally added to Annex LIII, prohibiting any EU entity from providing support to them. Simultaneously, the sanctions list has been expanded to include 20 additional Russian banks and four third-country financial institutions connected to Russia's SPFS messaging network—an alternative system built by Russia to bypass SWIFT, with nodes spanning Kyrgyzstan, China, the UAE, Uzbekistan, and Kazakhstan. The ban also covers "netting transactions," prohibiting EU entities from engaging in such offsetting operations with Russian agents, closing a technical loophole long used to obscure fund flows. The inclusion of the Kyrgyzstan-based exchange TengriCoin (operating the platform Meer.kg) in this round of sanctions is significant. The Council of the EU explicitly noted that TengriCoin was listed due to its high volume of A7A5 stablecoin transactions. A7A5, issued by the Kyrgyzstan-registered Old Vector LLC, was characterized in a report by the on-chain intelligence firm Chainalysis as a "purpose-built settlement rail" specifically designed to reconnect sanctioned Russian enterprises to the global financial system. Chainalysis pointed out that A7A5 has processed a cumulative $119.7 billion, with the 2026 Crypto Crime Report recording over $93.3 billion in volume within a single year. Following the OFAC sanctions on Garantex, some funds shifted to Grinex—which ceased operations after claiming a $13.74 million loss from a hack by "Western intelligence agencies" on April 16, 2026. Moscow has clearly exhausted the Garantex → Grinex path and is currently seeking its next relay station. The signal sent by the TengriCoin case is clear: third-country VASPs that facilitate the circulation of Russian state-related crypto tools are within the range of EU sanctions, regardless of where they are registered. Notably, the data trend for A7A5 is positively correlated with the intensity of sanctions. Chainalysis observed that as traditional sanction channels have narrowed, A7A5's transaction volume has continued to climb, indicating that demand has not shrunk due to sanctions—it has simply shifted tools. In this round, the EU also prohibited the provision of any MiCA-regulated crypto services to individuals and entities in Belarus, covering everything from trading to custody. This puts pressure on compliant exchanges expanding in Europe: any residual services provided to Belarusian or Russian users could be deemed a violation. May 24 is the hard deadline for the regulation to take effect. For crypto service providers licensed or seeking licenses in the EU market, the compliance window is less than four weeks. For Russia, which is attempting to maintain its connection to the international financial system via crypto rails, Brussels is not just blocking a few wallet addresses this time, but the entire service provider layer. As for the effectiveness—the transaction volume of A7A5 may provide a more honest answer than any official announcement.
