Harris Irafan warns that the "macroeconomic exposures" of Islamic banks constitute a "ticking time bomb" of a "billions of dollars" in "unhedged currencies and rates". The difficulty, complexity and expense of hedging these in the correct Islamic manner is such that as of 2015, the Islamic Development Bank "was hemorrhaging cash as if it were funding a war. It simply couldn't swap dollars for euros or vice versa on an ongoing basis without resorting to the conventional markets." Regional Islamic banks in the Middle East and Malaysia did not have "specialized personnel trained to understand and negotiate Sharia-compliant treasury swaps" and were not willing to hire the consultants who did.
