The deputy secretary of the US Treasury, William Cohen said oil sanctions placed by the US and the EU has cost Iran’s economy about $80 billion since the beginning of 2012. About $100 billion of its assets have been frozen and out of the reach of the Iranian regime. Oil sanction alone has cost Iran $5 billion a month. This means that after 6 months which is the time span for any comprehensive deal on Iran’s Atomic program, this regime would lose about $30 billion just from oil revenue.
