ISIS made $ 1 bn in revenue in 2015: US Treasury

ISIL’s sources of income include oil and gas sales, extortion and taxation, external donations, kidnapping-for- ransom, and previously, bank looting, Daniel Glaser, the Treasury’s assistant secretary for terrorist financing said.

“We estimate that in 2015, ISIL made approximately USD 1 billion dollars in total revenue, USD 500 million of which came from the sale of oil, primarily through populations under its control,” Glaser said, using the US’s preferred acronym for Islamic State. 

“We also estimate that ISIL may have earned as much USD 350 million per year, by extorting funds from the local population and in connection with the financial and commercial activity taking place in the territory it controls,” he said on Thursday in written testimony for a House of Representatives.
