By mid-2026 Indonesia’s Islamic financial assets reached Rp3,264 trillion (about $200 billion), up nearly 10 percent year-on-year, while the 12th IIMEFC received 538 papers from 49 countries, up from 348 papers and 37 countries the previous year.

The article argues that Bank Indonesia Institute and the Scopus-indexed Journal of Islamic Monetary Economics and Finance are shifting the field from normative claims to econometric evidence on transmission, allocation, and stability of equity-based contracts.

It concludes that this “evidence premium” is necessary for Islamic finance to influence policy in emerging markets, even as data gaps on informal MSMEs and concentrated research capacity remain constraints.

By mid-2026, Islamic financial assets in Indonesia had climbed to Rp3,264 trillion (about $200 billion), close to 10 percent more than a year earlier. A less-noticed figure came out of Jakarta this year too. When the city hosted the 12th International Islamic Monetary Economics and Finance Conference (IIMEFC), 538 papers came in from 49 countries, up from 348 papers and 37 countries the year before.
