Income for the Islamic State has dropped by 80-percent over two years. According to a study of its finances, an extended air campaign, and loss of territory, hit the oil and tax revenue streams for the militant group. The self-proclaimed caliphate earned an average of $81 million in the second quarter of 2015. This year during the same period, the group has only earned an estimated $16 million. The report comes from IHS Markit, a global data monitoring company.
