According to S&P Global Ratings, the outlook for 2018 is uncertain because of geopolitical risks and economic uncertainties. Sukuk issuance was strong last year with $97.9 billion, up 45.3% from the $67.4 billion issued in 2016. So-called "jumbo issuances" were seen in Saudi Arabia and other Gulf Cooperation Council (GCC) economies in 2017. Mohamed Damak, senior director at S&P Global Ratings, said the first two months of 2018 had been marked by a good performance for local currency issuance and a drop in foreign currency issuance. He added that 2018, as a whole, was expected to see a drop in sukuk issuance, with expectations for around $70-80 billion in total. There are a number of reasons for this, including central bank tightening, lower financing needs of GCC banks and geopolitical risks. Another reason for lower sukuk performance could be the slow progression of the standardization in the sukuk market.
