Iran's rial slid to a record 2.02 million per dollar on Aug. 24, the same week Washington named digital assets as a sanctionable sector for the first time. The move takes direct aim at the IRGC's bitcoin mining operation, which reportedly controls most of the country's mining capacity and has helped Tehran dodge dollar sanctions for years.
Iran's currency collapsed to a record low this week, and the Trump administration's newest sanctions package puts crypto in its crosshairs for the first time. The timing links two threads Washington has watched separately for years: a currency in freefall and a state-linked bitcoin mining network that has kept dollars flowing regardless.
A Record-Low Rial Meets a New Sanctions Wave
Iran's open-market exchange rate slid to roughly 2.02 million rials per dollar this week, down from 1.53 million rials during Q1 this year. The slide came the same week the Trump administration rolled out Operation Economic Outcast, a sanctions package first announced on August 19 that added more than 60 entities to the Treasury's blacklist.
Treasury Secretary Scott Bessent said the goal is to force Iran's state-run Bank Melli to go "shuttered and dark" or lose dollar access entirely, and warned that secondary sanctions on Iran's trading partners could follow within weeks. Meanwhile, the IMF now projects Iran's inflation will average 68.9% in 2026, with the economy contracting 5.4%.
The IRGC's Bitcoin Mining Workaround
None of this is new to Iran's crypto sector, which has spent years building around sanctions. Tehran legalized bitcoin mining back in 2019, letting licensed operators tap industrial electricity priced at roughly $0.004 per kilowatt-hour in exchange for selling their mined coins to the central bank.
State-affiliated farms linked to the Islamic Revolutionary Guard Corps now control an estimated 65% of that mining capacity, and Iran-based miners have accounted for 3% to 7% of global bitcoin hashrate since 2019. Iran's broader crypto ecosystem reached $7.78 billion in value last year. Chainalysis estimated IRGC-linked wallet addresses alone received more than $3 billion in Q4 2025. Elliptic separately found the central bank had built up at least $507 million in USDT to help prop up the rial.
Washington's Crackdown so Far
The Treasury's Office of Foreign Assets Control sanctioned Nobitex, Wallex, Bitpin and Ramzinex in June, targeting Nobitex specifically because it processed more than half of Iran's digital-asset inflows. That action followed a nearly $500 million seizure of Iran-linked crypto assets in April, after a cyberattack that drained more than $90 million from Nobitex itself in mid-2025.
TRM Labs separately found Iran's total crypto flows actually cooled to $3.7 billion in 2025, as the Nobitex hack, Tether freezes and mounting geopolitical risk eroded trust in the system.
Can Iran Outlast the Pressure?
Bessent has floated secondary sanctions on countries that keep trading with Tehran, which would squeeze the intermediaries Iran's crypto network relies on to convert stablecoins into usable cash. Iran's mining operations face a more basic constraint too: the country's power grid is already strained, and further military escalation or blackout-driven rationing could do more to shut down IRGC-linked mining farms than sanctions lists ever have.
