Russia sanctioned Alexander Browder, a 17-year-old British student, after his crypto research helped British officials target a ruble-backed stablecoin network accused of moving funds for Moscow’s war economy.
Summary
- Russia sanctioned 17-year-old Alexander Browder after his crypto research helped British officials target the A7A5 stablecoin network.
- Browder’s investigation linked the A7A5 to allegations of sanctions evasion and financial channels linked to the Russian war economy.
- The British Foreign Office said the A7A5 was part of a network designed to circumvent Western sanctions against Russia.
TASS, Russia’s official news agency, reported Tuesday that Browder was one of five British citizens added to Moscow’s “exclusion list” after Russia accused them of spreading what its Foreign Ministry called false statements about the country.
Russia targets young researcher after A7A5 investigation
Browder, the son of Kremlin critic Sir Bill Browder, spent 18 months studying A7A5, a ruble-pegged stablecoin issued by Kyrgyzstan-based Old Vector and hosted on the Tron and Ethereum blockchains. According to its Global Cryptocurrency Laundering Database website, its work appeared in a Henry Jackson Society report titled “Confronting the Illicit-Finance Hydra in Crypto Markets,” which examined 164 cases of crypto laundering over two decades.
The teenager also advised British ministers before Britain announced new sanctions against entities linked to A7A5. In comments to Metro, Browder said Russian sanctions had not intimidated him and argued that Moscow’s response showed his work had “struck a nerve.” On X, he described himself as the first high school student sanctioned by an authoritarian government for speaking out against corruption.
UK says A7A5 helped circumvent Western sanctions
According to a May 26 British Foreign Office statement, A7A5 was part of a network built to circumvent Western sanctions and processed more than $90 billion in transactions last year. Foreign Secretary Yvette Cooper said Britain was targeting “the infrastructure that supports” Russia’s war economy.
Browder’s research estimates that rogue states, including Iran and North Korea, have laundered approximately $350 billion in illegal funds, approximately half of which is believed to flow through the A7A5 network. Elliptic, a blockchain analytics company, reported in January that A7A5 processed more than $100 billion in transactions in its first year.
Western governments extend crypto sanctions
The May 26 British designations targeted 18 entities linked to the alleged network. According to the British government, the list included a Kyrgyz bank suspected of enabling payments and a crypto exchange accused of sending more than $1.5 billion to Moscow.
At the same time, European authorities have also taken action against crypto services linked to Russia. In April, the European Union introduced its 20th sanctions package and banned crypto service providers based in Russia. The European package, also named A7A5, and another ruble-backed stablecoin, RUBx.
Reuters reported last month that Kyrgyzstan had closed 50 businesses over sanctions evasion concerns. Kyrgyzstan’s Justice Ministry said the companies posed a “high risk of sanctions,” but did not name them publicly.
Moscow adds four more Britons to arrest list
In addition to Browder, TASS identified the sanctioned British citizens as Washington Post journalist Catherine Belton, CTG chief executive Alice Mary Laugher, Chelsea Group founder Richard Nicolas Westbury and The i Paper journalist Richard Holmes.
The Russian Foreign Ministry said the list would continue to grow in response to what it called unfriendly actions by British authorities. Browder told GB News that Moscow’s decision could make people even more reluctant to work with the A7A5, although he linked that outcome to how forcefully governments enforce sanctions.
