Earlier this week, the open market exchange rate of the Iranian rial fell to approximately 2.02 million rials per dollar, down from 1.53 million in the first quarter of this year. This drop occurred the same week the Trump administration launched Operation "Economic Outcast" — a comprehensive sanctions package first announced on August 19, which added over 60 organizations to the Treasury Department's blacklist.
Notably, it for the first time designated digital assets as a sector subject to sanctions, alongside technology, gold, aviation, and shipping.
Treasury Secretary Scott Bessent stated that the goal is to force the Iranian state-owned "Bank Melli" to "shut down and cease operations" or lose all access to the dollar entirely, warning that secondary sanctions on Iran's trading partners could follow within weeks. The International Monetary Fund currently forecasts Iran's annual inflation to average 68.9% in 2026, with the economy contracting by 5.4%; prices for rice and beef have already surged sharply since the pressure intensified.
The IRGC's Bitcoin Mining Machine
None of this is news to Iran's cryptocurrency sector, which has for years been devising ways to circumvent restrictions. In more detail, Tehran legalized Bitcoin mining back in 2019, allowing licensed operators to use industrial electricity at a rate of about $0.004 per kilowatt-hour in exchange for selling the mined coins to the central bank.
State-linked farms controlled by the Islamic Revolutionary Guard Corps (IRGC) are currently estimated to control 65% of this mining capacity, with Iran's share of the global Bitcoin hashrate ranging from 3% to 7% since 2019, mining coins worth between $1.35 and $3.15 billion at various periods.
Beyond mining, the total value of Iran's cryptocurrency ecosystem reached $7.78 billion last year; Chainalysis estimates that over $3 billion flowed into wallet addresses linked to the IRGC in Q4 2025 alone, while Elliptic separately determined that the Central Bank of Iran had accumulated at least $507 million in USDT to support the rial's exchange rate.
Washington's Crypto Crackdown to Date
Washington has been gradually dismantling this network for months, as evidenced by the Treasury's Office of Foreign Assets Control (OFAC) sanctioning Nobitex, Wallex, Bitpin, and Ramzinex in June.
Nobitex alone handled over half of the digital asset inflow into Iran and helped the central bank move hundreds of millions in stablecoins, while also providing regime representatives access to international exchanges.
This move followed the Treasury's seizure in April of nearly $500 million worth of cryptocurrency assets linked to Iran after a cyberattack that stole over $90 million from Nobitex itself (in mid-2025), forcing the central bank to reroute its stablecoin flows across several blockchains to keep the system functioning.
TRM Labs separately found that Iran's total cryptocurrency flows in 2025 actually shrank to $3.7 billion, as the Nobitex hack, Tether fund freezes, and mounting geopolitical risk undermined confidence in the system.
Can Iran Withstand the Pressure?
Bessent has floated the idea of secondary sanctions against countries continuing to trade with Tehran, which would hit the very intermediaries Iran's crypto network relies on to convert stablecoins into cash. Iran's mining operations are vulnerable at a more basic level as well: for instance, the country's power grid is already strained, and further military escalation or power rationing due to blackouts could have a greater impact on shutting down IRGC-linked mining farms than any sanctions list ever could.
Put simply, the rial's plunge and the new sanctions package are just the latest chapter in a struggle our department has tracked for years, one where every crackdown on Iran's "cryptocurrency lifeline" has so far met a new workaround.
