  • How the FTSE ST Singapore Shariah Index Selects Stocks for Ethical Investing
    March 22, 2026, 12:47 AM EDT. The FTSE ST Singapore Shariah Index (SGX: FSTAS) tracks companies on the Singapore Stock Exchange (SGX: S68) that comply with Islamic finance principles, excluding interest-based activities and restricted industries. It screens firms using two tests: business activity and financial ratio. Prohibited sectors include conventional finance, gambling, alcohol, tobacco, adult entertainment, pork-related businesses, and arms manufacturing. For example, major banks DBS Group Holdings (SGX: D05) and Oversea-Chinese Banking Corporation (SGX: O39) are excluded due to reliance on interest income. Permissible businesses like Singapore Telecommunications (SGX: Z74) qualify if they pass both screens. The financial test limits interest-based debt (gearing ratio below 33.33%) and restricts cash and interest-bearing securities to under 33.33% of total assets. The index updates semi-annually to maintain compliance and ethical investing standards.
