(Oilprice) In June 2014, computer files captured from a courier for the Islamic State shortly after the fall of Mosul revealed that the group had assets of $875 million, largely gained in the sacking and looting of Mosul and its central bank.
The size of the group’s bank account has now risen to an estimated $2 billion dollars, thanks in part to revenues from ransom paid for kidnapped foreigners and more pillaging. However, oil remains the group’s primary source of income.
