Iran is turning to Bitcoin and Tether as sanctions and a tightening economic blockade make it increasingly difficult for the country to access conventional international financial networks.
The Iranian central bank has relaxed long-standing foreign-exchange controls, allowing exporters to use Tether and Bitcoin for cross-border transactions through domestic crypto exchanges. The change gives businesses a way to move export proceeds directly into imports while avoiding some of the restrictions and exchange rates imposed by the state.
The shift comes as U.S. economic pressure on Iran intensifies, with sanctions and restrictions on oil exports putting further strain on the country’s access to foreign currency and international banking channels.
For Iranian businesses, stablecoins such as Tether’s USDT offer a digital dollar alternative that can be transferred across borders without relying on traditional correspondent banking networks. Bitcoin provides another payment rail outside the conventional financial system.
Iran’s crypto activity is already substantial. Nearly $10 billion in cryptocurrency transactions were processed in the country in 2025, according to the Financial Times. Iran also has significant Bitcoin-mining capacity, supported in part by relatively cheap domestic energy.
The strategy, however, comes with significant risks. U.S. sanctions apply to Iranian digital-asset exchanges, and the Treasury Department has warned that foreign financial institutions and other non-U.S. persons can face sanctions exposure for significant transactions involving designated Iranian crypto exchanges. The U.S. Treasury has specifically identified Iranian exchanges as blocked financial institutions under its sanctions regime.
Washington has also targeted crypto businesses linked to Iranian illicit finance. In August, the Treasury sanctioned several digital-asset exchanges and related entities, saying they had helped finance Iran’s Islamic Revolutionary Guard Corps and facilitate illicit financial activity.
The growing use of Bitcoin and Tether highlights an increasingly important role for digital assets in countries cut off from traditional financial infrastructure. But while crypto can provide alternative payment channels, the scale of Iran’s financial needs means it is unlikely to fully replace access to conventional banking and foreign-currency markets.
For Tehran, the move is less a bet on crypto than a response to financial isolation — turning blockchain-based assets into another tool for keeping trade moving as sanctions tighten.
