Russia sanctions 17-year-old over ruble stablecoin report

Russia has imposed sanctions on 17-year-old British national Alexander Browder after a March report by Browder alleged the ruble-pegged stablecoin A7A5 was backed by deposits from Promsvyazbank and used to bypass Western sanctions tied to the war in Ukraine.

Browder wrote on social media that his research for the Global Cryptocurrency Laundering Database prompted the designation and described himself as “sanctioned by an authoritarian regime for uncovering corruption.” His father, campaigner Bill Browder, called his son “the first high school student in the world to be sanctioned by an authoritarian regime.”

The March report said A7A5 derives its ruble peg from deposits provided by Promsvyazbank and that the token has been used to convert on-chain value into cash accessible to actors seeking to avoid restrictions. A security firm analysis released this week found the stablecoin processed more than $110 billion in on-chain transactions.

European Union authorities sanctioned A7A5 in October 2025, saying the token was intended to bypass war-related financial restrictions. U.S. and U.K. officials have also imposed restrictions. Supporters of those measures note that some exchanges and jurisdictions still enable conversions from the coin into cash.

Bill Browder urged Western governments to press exchanges and the countries that host them to cut off conversion routes. He wrote: “A7A5 holds value through its ability to be converted into cash by criminals. Western governments need to put pressure on the specific exchanges which allow the conversions to happen and the countries which facilitate these exchanges.”

Russian authorities have increased restrictions on outside critics and on reporting tied to sanctions issues, and the government has banned some journalists from entering the country. In April, lawmakers advanced a draft law titled “On Digital Currency and Digital Rights” that would impose criminal penalties for unlicensed digital-asset services, require registration with the central bank and could ban unlicensed crypto platforms from July 2027.

The designation of Browder and the actions against A7A5 come as regulators, investigators and crypto platforms contend with how digital tokens move across borders and how on-chain value can be converted into fiat cash.
