The "Islamic State of Iraq and Syria" (ISIS) has lost more than 60% of its territory and 80% of its revenue, an analysis firm said Thursday (June 29th).
In January 2015, ISIS controlled about 90,800 square kilometres, but by this month, that number had dropped to 36,200, said IHS Markit.
The biggest fall was in the first six months of this year, when ISIS lost around 24,000 square kilometres of territory.
"Three years after the 'caliphate' was declared, it is evident that the group's governance project has failed," said Columb Strack, senior Middle East analyst at IHS Markit.
The remaining parts of the "caliphate" are unlikely to survive to the end of the year, IHS said, noting that the decline has damaged ISIS's ability to collect revenue from oil production, smuggling, taxation, confiscation and the like.
IHS said ISIS's average monthly revenue has fallen by 80%, from $81 million in the second quarter of 2015 to just $16 million in the second quarter of 2017.
