The Iranian government will allow licensed cryptocurrency miners to resume operations today following a three-month ban imposed by former President Hassan Rouhani on May 26, 2021.

The initial ban was put into effect due to concerns over the stability of the country’s unreliable power grid.

The Middle Eastern country experienced widespread power outages in the summer, which former President Rouhani attributed to extreme heat. On some days, the heat topped 120 degrees Fahrenheit, or nearly 49 degrees Celsius.

In light of the power outages and a water shortage, Rouhani decided to ban crypto mining during the heat to ensure citizens could keep their air conditioners running — although doubts have been expressed in some quarters about how much power crypto mining actually consumes in the country. With the heat dying down and Ebrahim Raisi taking office as president on Aug. 3, 2021, the crypto mining ban has been lifted.

An estimated 4.5% to 7% of the world’s cryptocurrency mining is done in Iran. It may come as little surprise that Iran boasts some of the cheapest electricity prices in the world thanks to abundant fossil fuel resources such as natural gas.

Despite the ban, underground mining reportedly continued, and on Wednesday, news broke that Ali Sahraee, the director of Teheran’s Stock Exchange (TSE), had resigned after the state-run media reported that cryptocurrency mining was taking place at the exchange during the ban.

TSE leadership first denied the existence of the mining operation, but later, executive deputy director Beheshti-Sarsht admitted that the TSE should be held accountable for the operation.
