Since it was established in 1979, the Islamic Republic of Iran has been subjected to a steady stream of sanctions. Over the years, their depth and breadth have dramatically increased, often gradually, at times by leaps and bounds. The existing patchwork of sanctions reflects diverse policy objectives and disparate legal frameworks, developed over 34 years and implemented by different governmental and institutional bodies. This interactive highlights the major unilateral, multilateral and international sanctions imposed on Iran and breaks them down by year, economic impact, trigger, targets and reversibility. Mouse over each bubble for more details on the sanction, and click on tabs to sort them into different categories.
