How Indonesia governs its Sharia banks, sovereign sukuk and halal stock market

In the country with the world's largest Muslim population, Sharia and conventional banks share one supervisor, alongside a very active sukuk market.

Islamic finance in Indonesia covers the banks, capital markets, takaful insurers and finance companies that operate under Sharia principles, supervised by the OJK and aligned with fatwas from the National Sharia Council, DSN-MUI, rather than with general banking law alone.

Who supervises Sharia finance in Indonesia?

The Otoritas Jasa Keuangan, or OJK, oversees Islamic banks, capital markets, insurers and finance companies. Bank Indonesia keeps monetary policy and develops Sharia liquidity instruments, while the DSN-MUI provides a single religious reference point for the whole sector, which avoids conflicting opinions between institutions.

DSN-MUI fatwas as the religious foundation

The National Sharia Council of the Indonesian Ulema Council issues fatwas contract by contract: murabaha, mudaraba, ijara, wadiah. They do not carry statutory force on their own, but regulation requires institutions to follow them, which keeps product design consistent across the country.

A mandatory Sharia board inside every institution

Each provider must appoint a Dewan Pengawas Syariah with at least three members, or two for small entities. Members need a DSN-MUI recommendation and certified training, and cannot sit on the board of a competitor. The board checks that products match national fatwas.

Aceh, where conventional finance had to step back

Holding special autonomy and applying Sharia law, Aceh province adopted Qanun 11 of 2018, requiring every financial institution to operate under Islamic law within three years. Several conventional banks converted their branches to Sharia operations, while others chose to leave the province entirely.

BUS, UUS and BPRS: the three types of Sharia bank

Law 21 of 2008 on Sharia banking distinguishes the full-fledged Islamic bank, known as BUS, the Sharia business unit housed inside a conventional bank, known as UUS, and the Sharia rural bank, or BPRS, serving small traders, farmers and households in underserved areas.

Why three state-owned subsidiaries merged in 2021

In 2021 the Sharia subsidiaries of three state banks, BRI Syariah, Mandiri Syariah and BNI Syariah, were combined into Bank Syariah Indonesia. The stated aim was to create a public player large enough to finance major projects and compete on cost with conventional lenders.

Islamic windows: when separation becomes compulsory

Following Law 4 of 2023 on strengthening the financial sector, regulation POJK 12 of 2023 requires a bank to separate its Sharia unit once it exceeds half of the parent's assets or fifty trillion rupiah, by creating an Islamic bank or transferring the unit.

Bank Muamalat, the starting point in 1991

Founded in 1991, Bank Muamalat was the country's first Islamic bank, backed by the ulema council and Muslim entrepreneurs. Its history recalls the long period when the sector rested on a handful of private pioneers before the dedicated legal framework arrived in 2008.

Sovereign sukuk under the SBSN law

Law 19 of 2008 allows the state to issue Surat Berharga Syariah Negara, sukuk backed by public assets or budget projects. The Ministry of Finance uses them to fund roads, bridges and schools, and also offers series designed specifically for individual savers buying small amounts.

February 2018 and Asia's first sovereign green sukuk

In February 2018 Indonesia placed 1.25 billion dollars of five-year green sukuk, becoming the first Asian country to sell sovereign green bonds internationally. Proceeds fund renewable energy, waste management and sustainable tourism, and the government publishes allocation reports on how the money is spent.

Sharia equities: the JII index and compliant online trading

Since 2000 the Jakarta exchange has calculated the Jakarta Islamic Index, made up of thirty liquid stocks screened under Sharia criteria. In 2011 it opened a compliant online trading system that, among other things, blocks short selling and margin purchases for Muslim investors.

Knowing Islamic finance is not the same as using it

According to the OJK national survey published in 2024, around 39 percent of Indonesians understand Sharia finance, yet only 12 percent use its products. This gap pushes the regulator and banks to invest in financial education and in digital distribution of accounts and financing.
