Malaysia's efforts to create a market for ethical Islamic bonds are the latest in a series of government-led initiatives to develop Islamic finance, but further expansion will require a greater buy-in from a sometimes reluctant private sector. In May, sovereign wealth fund Khazanah Nasional launched the country's first sustainable and responsible investment (SRI) sukuk, nearly two years after the format was first announced by the government. Last year, $74.9 billion worth of sukuk were issued out of Malaysia but only $13.5 billion came from corporate issuers. There is little sign of this changing soon.
