According to S&P Global Ratings, the sukuk market enjoyed a strong start to the year but it may not last. S&P Global Ratings Head of Islamic Finance, Mohamed Damak said high levels of liquidity in Indonesia, Turkey's efforts to tap all available financing sources, and the return of Qatari and Saudi Arabian issuers to the market have boosted issuance of sukuk 17.6% in the first five months of 2019. S&P expects the total Sukuk issuance will average $105 billion-$115 billion this year, assuming the Brent oil price stabilizes at $55 per barrel. This follows a mild performance in 2018 when issuance dropped to $114.8 billion, a 5% decline compared with 2017; US dollar Sukuk alone fell by 15% year on year. Tightening liquidity conditions, high geopolitical risks in the Middle East, and challenges inherent to sukuk issuance will likely dampen sukuk market performance in 2019.
