The unofficial exchange rate for the Rial fell to 33,500 rials to the dollar in informal currency exchanges. It fell 13% on Oct. 1, 2012. At the end of 2011 the exhange rate was about 13,000 to the dollar, and the rial has already lost 75% of its value as a result of economic sanctions over its nuclear program. Ahmadinejad and the Iranian government risk jeopardizing most of the social gains to improve living conditions as Iran's economy faces the full force of economic sanctions.
