Ruble Stablecoin A7A5 Collapses Under Sanction Pressure

The ruble stablecoin A7A5 was designed to evade Western sanctions by allowing Russian businesses to move money beyond reach of restrictions. It worked for a year, with over $100 billion flowing through it, but its transaction volumes are now down 96% and its primary exchange is offline.

A7A5 was pegged to the Russian ruble and backed by Promsvyazbank (PSB), a state-owned bank sanctioned for serving Russia's defense sector. The token held its value at one-to-one with the ruble, making it attractive to businesses looking to bypass USDT, which can be frozen at any time.

Sanctions on A7A5 and its supporting infrastructure were enforced through blockchain analytics, stalling the token's growth. In 2025, the US, UK, and EU sanctioned A7A5 in three waves, affecting exchanges where A7A5 was converted into other assets, particularly USDT.

The sanctions made it difficult for users to access A7A5, as blockchain analytics firms like Elliptic traced funds from sanctioned entities across public ledgers. This led to widespread freezing of USDT obtained by swapping A7A5 on global exchanges and the delisting of A7A5 from decentralized trading venues.
