Details of the scam emerged during a hearing of a specially-convened Foreign Affairs sub-committee set up to examine Britain's role in Isil financing. The hearing was told that Isil finance chiefs would play the international stock markets using cash looted during their 2014 take over of Mosul, in which the group got its hands on an estimated $429m from the city's central bank. They also used money "siphoned off" from pension payments that are still being made by the Iraqi government to civil servants living in the city. The details were revealed to the hearing by John Baron, the sub-committee's chair, who demanded to know whether the British government - which has pledged to help cut off Isil's finance networks - was taking proper action against it. "The cash that Isil has looted, along with siphoned off pension payments, is routed into Jordanian banks and brought back into the system via Baghdad," he said. "That allows the system to be exploited by Isil, in that they take a turn (profit) on the foreign currency actions and siphon that cash back." The profits were channeled back into Isil coffers by "hawala" transfers, an unregulated system of money transfer whereby cash payments are made via agents in one country after a similar amount is presented as collateral in another. Tobias Ellwood, a junior Foreign Office minister, admitted to the committee that there was a "porousness" in the local financial system but said that work was now underway to shut it down. It had been done without the active connivance of bank staff, he added. In December, the Central Bank of Iraq named 142 currency-exchange houses in Iraq that the US suspected of moving funds for Islamic State. It banned them from its twice-monthly dollar auctions in a bid to stop the terror group getting its hands on the cash - a main source of exchange in war-torn Iraq. But Mr Ellwood conceded: "Iraq could have moved faster on this". Asked if the similar moves had been made in Jordan, he said he was unable to give an answer. "Jordan plays an important role in the (anti-Isis) coalition," he added. "Work is being done to close it down, I don't think there is anything near as much from that source of revenue as before." The committee heard claims that Isil's "rake off" from foreign currency speculation was a "significant part of their income stream", although Mr Ellwood said he thought that estimates of $20m were excessive.
ISIS is reportedly making millions of dollars by speculating on the stock market . A new report suggests that ISIS has used some of the funds that it looted during its takeover of the Iraqi city of Mosul ( including $ 429 million from its central bank ) to invest in legitimate stock markets in the Middle East . The report suggests that it is earning $ 500 m a month from such activities . The profit it makes from currency speculation is believed to be paid back to the government via unsuspecting financial transactions in Iraq and Jordan . Unsurprisingly , this form of revenue has become one of its main sources , alongside earnings from oil smuggling , and taxes on individuals living in areas that fall under its control .
