Howard J. Shatz has been studying the finances of ISIS and its precursors since 2006. He offers perhaps the most comprehensive view we’ve seen so far of how the group spends its money:
ISIL historically has paid its members (yes, it maintains payroll sheets) based on a flat monthly rate per person and then additional fixed amounts for each wife, child and dependent unmarried adult woman in the household. In Anbar, Iraq, the rate was $491 per year in 2005 and 2006, and then about $245 per year per dependent; the rate was similar in Mosul in 2007 and 2008. These payments to family are meant to continue if the ISIL member is captured or killed—a primitive form of life insurance. If enough members are captured and killed, however, these costs start to mount.
ISIL also pays rent for its members in some cases—payments that might be bonuses to high-performing members, although we cannot be sure—and medical expenses for some members and their families. In the past, the group has sometimes hired lawyers to help get captured members out of jail. And it runs safe-houses and has to buy equipment. Guidelines published by a predecessor of the group say that expense reimbursements should be filled out in triplicate and explain where each copy goes within the organization. We don’t know for sure whether ISIL today is making money or even breaking even, but at least in Anbar from 2005 to 2006, the money was being spent as fast as it came in.
His takeaway:
Even if ISIL is making $3 million per day—at the higher end of the various estimates out there—then it makes slightly more than $1 billion per year. Just to be conservative, in case ISIL is doing more business than we’re aware of, let’s double that to $2 billion per year. Although exact totals are difficult to find, in 2013, before ISIL’s advance, the Iraqi government spent far more than $2 billion per year running the governorates ISIL now controls, including salaries to civil servants, other costs of service provision and investment spending. That means ISIL likely isn’t keeping up the same level of service that the Iraqi government once did. True, ISIL need not maintain that level—it hardly rules with the consent of the governed. But it’s not only a problem that those under its rule can rebel, as happened in 2007 and 2008; with the exception of oil, the group’s continued revenue-raising also depends on there being enough money to skim and extort from the economy, and this requires some minimum level of services and economic activity.
