At a conference on Islamic finance in Singapore many experts warned that the industry depends too heavily on oil and gas for revenue. According to expert Rushdi Siddiqui the industry saw a 43% drop in sukuk issuance and he argued for the need to 'delink' Islamic finance from oil and gas. Other participants noted that the industry's growth is slowed by the 'perception price' that comes with political volatility in the Middle East and Malaysia.
