The emergence of sukuks — so-called Islamic bonds — was arguably the most significant development in Sharia-compliant capital markets of the last 20 years.

However, only 4,650 deals have taken place since 2005 and issuance has declined from a peak in 2012, according to S&P Global Ratings. That is despite a large pool of investors that can only invest in Sharia-complaint assets, according to S&P. Sharia law prohibits levying interest on debt, making traditional capital market deals out of bounds for these investors.
