For Iranian families, sanctions rarely arrive as policy language. They arrive as a number on a currency board. In the squeeze of 2011 and 2012, the rial shed nearly 38 percent of its value in a year, and every imported medicine, part and staple priced in dollars moved out of reach. That was the human side of a pressure campaign whose paperwork was written in Washington.
The legal machinery is older than the squeeze. Executive Order 12170 blocked Iranian government property in November 1979; an import ban followed in 1987; 1995 brought orders prohibiting transactions with Iran and the development of its petroleum resources. The escalation then stacked fast: UN Security Council Resolution 1929 in June 2010, passed with Russian and Chinese support, the toughest international measures Iran had faced; the CISADA law the same month, hitting refined fuel sales, grave human-rights abuses and Iran’s access to world finance; and the December 2011 defense authorization that sanctioned the Central Bank of Iran.
By 2012 the orders came in a burst. February brought EO 13599, blocking all Iranian government and financial-institution assets in US jurisdiction; April, EO 13606, aimed at repression via information technology and at the “digital guns for hire” who build surveillance systems; May, EO 13608 against sanctions evaders. The EU’s oil embargo took full effect on July 1, and on July 30 the president signed his fifth Iran executive order inside 12 months, extending sanctions to petrochemicals and to any payment workarounds for Iranian oil. The same week, Treasury hit China’s Bank of Kunlun and Iraq’s Elaf Islamic Bank under CISADA for knowingly moving significant business to Iranian banks already designated.
The White House’s own accounting, from a fact sheet dated July 31, 2012, is blunt. “Because of our efforts, Iran is under greater pressure than ever before”, President Obama had said that March, crediting sanctions with “virtually grinding the Iranian economy to a halt in 2011” and warning of “the prospect of even more crippling sanctions”. Iran’s own president, Mahmoud Ahmadinejad, called the measures “the most severe and strictest sanctions ever imposed on a country”. The results the sheet lists: oil sales disrupted by as much as 1 million barrels per day, an oil ministry acknowledging in 2011 that it was $100 billion short of the investment it needed, atomic energy chief Ali Salehi conceding sanctions had slowed the enrichment program, and firms from Ernst & Young and Daimler to Caterpillar, ENI and Total walking away.
The framework kept growing after the JCPOA’s pause. Sanctions lifted or waived under the JCPOA were re-imposed, by notice in November 2018 and EO 13846; later orders reached Iran’s iron, steel, aluminum and copper sectors, additional economic sectors with Iranian financial institutions blocked under EO 13902, petroleum and petrochemical designations effective October 11, 2024, and conventional-arms targeting under EO 13949. The guidance has tracked the times: UAV-related activities in June 2023, ballistic-missile procurement that October, shipping-evasion advice in April 2025, and teapot oil refineries in April 2026.
What this means for ordinary households is the part regulators now spell out too: humanitarian channels are carved open, including a 2020 general license for humanitarian trade involving the central bank or the national oil company, and medical-device authorizations dating to 2017. The 2012 fact sheet ended on the same tension the decade never resolved: “we hold open the door to diplomacy”. The pressure worked on the economy; the ledger for the people holding the rial has always been the harder one to balance.
