Ethical and Shariah-Compliant Investing in Indonesia: The World’s Largest Muslim Population
IDX Shariah Stocks, ISSI Index, Sukuk Negara, and Global Access for the Conscious Investor
13 June 2026 · 14 min read
Indonesia is home to over 230 million Muslims — the largest Muslim population of any country on earth. With a young, growing middle class, a government that actively promotes Shariah capital markets, and an economy projected to become the world’s fourth largest by 2030, Indonesia represents perhaps the single greatest untapped opportunity in ethical and Shariah-compliant investing.
The Indonesia Stock Exchange (IDX) maintains an official Shariah securities list, the government issues retail sukuk directly to citizens, and the financial regulator OJK has built a comprehensive framework for Islamic capital market products. This guide covers the full landscape for both local and international investors.
KEY HIGHLIGHTS
- 230+ million Muslims — the world’s largest Muslim population and a massive structural market for Islamic finance
- ISSI (Indonesia Sharia Stock Index) covers 500+ Shariah-compliant stocks — over 50% of all IDX-listed companies

- OJK (financial regulator) publishes the official Daftar Efek Syariah (Shariah Securities List) twice yearly
- IDX is the largest stock exchange in ASEAN by number of listed companies
- Bank Syariah Indonesia (BSI) is the world’s largest Islamic bank by market capitalisation
1. Indonesia: The Sleeping Giant of Islamic Finance
Whilst Malaysia has historically led in Islamic finance infrastructure and the Gulf states dominate in absolute capital, Indonesia’s sheer demographic scale makes it the market with the highest growth ceiling. The Indonesian government has recognised this and has aggressively developed the regulatory and product framework to serve it.
OJK (OTORITAS JASA KEUANGAN)
- Indonesia’s integrated financial services authority — regulates banking, capital markets, and insurance
- Publishes the Daftar Efek Syariah (DES) — the official Shariah Securities List — twice yearly
- Operates the Shariah Capital Market Roadmap to 2029
- Regulates all Islamic banks, takaful companies, and Shariah mutual funds
- Works alongside the DSN-MUI (National Shariah Board) for compliance rulings
IDX (INDONESIA STOCK EXCHANGE)
- Over 900 listed companies — the largest exchange in ASEAN by listing count
- Hosts ISSI (Indonesia Sharia Stock Index) and JII (Jakarta Islamic Index)
- Dedicated Shariah Online Trading System (SOTS) for compliant brokers
- Retail investor accounts have grown from 2 million (2019) to over 12 million (2025)
- Active sukuk market segment for government and corporate sukuk
DSN-MUI: The National Shariah Board
The Dewan Syariah Nasional — Majelis Ulama Indonesia (DSN-MUI) is the body that issues fatwa rulings for Islamic finance in Indonesia. Unlike some countries where screening is conducted by private organisations, Indonesia’s Shariah compliance framework is anchored by an official national body with legal authority. The DSN-MUI’s fatwa are the binding reference for all Islamic financial products in the country.
2. How Indonesia’s Shariah Screening Works
OJK publishes the Daftar Efek Syariah (DES) every May and November. All listed companies are evaluated against both qualitative (business activity) and quantitative (financial ratio) criteria.
BUSINESS ACTIVITY SCREENING
Core business must not involve:
- Gambling and games of chance
- Conventional financial services (interest-based)
- Alcohol, pork, and non-halal food production
- Adult entertainment
- Tobacco (subject to revenue threshold)
- Non-permissible revenue must be < 10% of total revenue
FINANCIAL RATIO SCREENING
Key thresholds:
- Total interest-based debt / total assets < 45%
- Non-halal income / total revenue < 10%
- Uses total assets as the denominator (similar to Malaysian methodology)
- Reviewed twice yearly against the latest audited financials
Indonesia’s 45% debt-to-assets threshold is notably more permissive than the 33% used by AAOIFI and most Gulf standards. This reflects the DSN-MUI’s consideration of Indonesia’s developing economy, where companies may require higher leverage for growth. Investors who prefer stricter screening standards should apply their own additional filters.
3. ISSI and JII: Indonesia’s Shariah Indices
Indonesia operates two primary Shariah stock indices, each serving a different purpose.
ISSI (INDONESIA SHARIA STOCK INDEX)
- Broad index covering all DES-listed securities
- 500+ constituents — over 50% of all IDX-listed companies
- Represents the full investable universe of compliant stocks
- Updated when the DES is published (May and November)
JII (JAKARTA ISLAMIC INDEX)
- Top 30 most liquid Shariah-compliant stocks
- Blue-chip benchmark — the “FTSE 30” of Indonesian Islamic equities
- Higher liquidity and market capitalisation requirements
- Reviewed twice yearly; the reference index for most Islamic equity funds
4. Key Shariah-Compliant Stocks on IDX
Indonesia’s Shariah-compliant universe includes many of the country’s largest and most liquid stocks. Below are notable names that commonly appear on the DES and JII.
| Company | Ticker | Sector | Index |
|---|---|---|---|
| Bank Syariah Indonesia | BRIS | Islamic Banking | JII |
| Telkom Indonesia | TLKM | Telecoms | JII |
| Astra International | ASII | Conglomerate / Automotive | ISSI (verify JII) |
| Unilever Indonesia | UNVR | Consumer Goods | JII |

Bank Syariah Indonesia (BSI)

It trades on IDX under ticker BRIS and is a JII constituent. For investors seeking pure-play Islamic banking exposure in the world’s largest Muslim market, BSI is the defining stock.

5. Sukuk Negara: Government Sukuk for Retail Investors
Indonesia has one of the most developed retail sukuk programmes in the world. The government issues sukuk directly to citizens through several product lines, making Shariah-compliant fixed income accessible to investors of all sizes.
| Product | Minimum | Tenor | Key Feature |
|---|---|---|---|
| Sukuk Tabungan (ST) | IDR 1 million (~$62) | 2 years | Floating rate; linked to BI rate; most accessible |
| Sukuk Ritel (SR) | IDR 1 million (~$62) | 3 years | Fixed rate; tradeable on secondary market |
| Project-Based Sukuk (PBS) | IDR 1 billion+ | Various | Institutional; funds specific government infrastructure projects |
| Green Sukuk | Varies | Various | Funds environmentally sustainable projects; USD and IDR tranches |
Retail Sukuk: A Model for the World
Indonesia’s retail sukuk programme is genuinely groundbreaking. With a minimum investment of just IDR 1 million (approximately $62), government-backed sukuk are accessible to virtually anyone. The proceeds fund national infrastructure — roads, schools, hospitals — giving investors both a halal return and the satisfaction of contributing to national development. Retail sukuk can be purchased through participating banks, securities firms, and fintech platforms during the offering window.
6. How to Invest: Brokers and Platforms
Indonesia’s broker landscape has evolved rapidly, with several platforms now offering Shariah-compliant trading features.
| Broker / Platform | Markets | Shariah Features | Best For |
|---|---|---|---|
| Mandiri Sekuritas | IDX | Shariah online trading (SOTS certified); DES filter | Local investors; reliable institutional platform |
| BCA Sekuritas | IDX | Shariah account option; integrated with BCA banking | BCA banking customers; ease of funding |
| Indo Premier Sekuritas (IPOT) | IDX + mutual funds | SOTS certified; Shariah mutual fund marketplace | Tech-savvy retail investors; fund access |
| Interactive Brokers (IBKR) | 150+ global markets | No built-in Shariah filter; use external screener | International market access; US stocks and ETFs |
| Bibit / Stockbit | IDX + mutual funds | Shariah filter built into app; robo-advisory option | Mobile-first; beginner-friendly; low minimums |
SETUP STEPS
- Open an account with a SOTS-certified broker (Mandiri Sekuritas, IPOT, or BCA Sekuritas)
- Request a Shariah trading account — this ensures your trades are routed through the SOTS system
- Complete KTP (national ID) verification and SID (Single Investor Identification) registration
- Fund via IDR bank transfer from any Indonesian bank
- For global access: open IBKR account separately for US and international exposure
What is SOTS?
The Shariah Online Trading System (SOTS) is a unique Indonesian innovation. Certified by the DSN-MUI, SOTS ensures that investors can only purchase DES-listed (Shariah-compliant) securities, automatically prevents short selling and margin trading (both non-compliant), and separates Shariah client funds from conventional pools. It is, in effect, a compliance-by-design trading system — the only one of its kind globally.
7. Shariah Mutual Funds (Reksa Dana Syariah)
Indonesia has a well-developed Islamic mutual fund industry, regulated by OJK and certified by DSN-MUI. These funds provide diversified access for investors who prefer managed exposure.
| Fund Category | Asset Class | Example |
|---|---|---|
| Reksa Dana Saham Syariah | Shariah Equities | Mandiri Investa Syariah; Manulife Syariah Sektoral Amanah |
| Reksa Dana Pendapatan Tetap Syariah | Shariah Fixed Income (Sukuk) | BNI-AM Dana Syariah; Trimegah Dana Obligasi Syariah |
| Reksa Dana Campuran Syariah | Shariah Balanced (Mixed) | PNM Syariah; Panin Dana Syariah Berimbang |
| Reksa Dana Pasar Uang Syariah | Shariah Money Market | Mandiri Pasar Uang Syariah; BNI-AM Dana Lancar Syariah |

8. Tax Considerations for Indonesian Investors
TAX SUMMARY
Capital Gains Tax: 0.1% transaction tax
Indonesia does not charge capital gains tax on listed equities. Instead, a 0.1% final tax is levied on the sale value at the point of transaction. This is automatically deducted by the broker.
Dividend Tax: 10% final tax
Dividends from Indonesian companies are subject to a 10% final withholding tax for individual resident investors. This is deducted at source. However, dividends reinvested in Indonesian businesses or financial instruments within a specified period may be exempt.
Sukuk Income: 10% final tax
Returns from sukuk (including Sukuk Negara) are subject to a 10% final tax on the profit-sharing or rental payments received. This is lower than the standard income tax rates and makes sukuk relatively tax-efficient.
9. Getting Started: Your First Ethical Portfolio from Indonesia
Indonesia’s Islamic finance ecosystem allows you to construct a fully halal portfolio from the ground up, using entirely local products or adding global exposure.
STARTER PORTFOLIO FRAMEWORK
Fixed Income Foundation (25-35%): Sukuk Negara
Start with Sukuk Tabungan (ST) or Sukuk Ritel (SR) during the next offering window. Government-backed, halal, and accessible from IDR 1 million. This is your safe base.
Local Equities (30-40%): JII Blue Chips
Build positions in JII constituents: BSI (BRIS), Telkom (TLKM), Unilever (UNVR), Kalbe (KLBF), Indofood (INDF). Use a SOTS-certified broker for guaranteed compliance.
Managed Funds (15-20%): Shariah Mutual Funds
Add a Shariah equity fund for diversification beyond your individual picks. Available from most local brokers and fund platforms like Bibit or IPOT.
Global Exposure (10-20%): International Markets via IBKR
Diversify internationally with US Shariah ETFs (SPUS, HLAL) or individual screened US stocks via IBKR. This also provides hard-currency diversification away from the rupiah.

Frequently Asked Questions
How do I check if a stock is on the DES?
The official Daftar Efek Syariah is published by OJK twice yearly and available on the OJK and IDX websites. Most SOTS-certified brokers also flag compliant stocks within their trading platforms. If you use a non-SOTS broker, always verify against the latest DES before placing a trade.
What is the difference between ISSI and JII?
ISSI is the broad universe — all DES-listed stocks (500+). JII is the top 30 most liquid from that universe, serving as the blue-chip benchmark. Think of ISSI as the “all shares” index and JII as the “top 30” index. Most Islamic mutual funds benchmark against JII.
Can I buy Sukuk Negara at any time?
No. Retail sukuk (ST and SR series) are offered during specific windows announced by the Ministry of Finance, typically several times per year. You must purchase during the offering period through a participating distribution partner (banks, brokers, fintech platforms). SR series can be traded on the secondary market after issuance, but ST series are held to maturity.
Is Astra International (ASII) halal?
Astra International has historically appeared on the DES, but its conglomerate structure — which includes Astra Financial (conventional financial services) — means its status requires regular verification. The financial services arm may cause it to fail screening in some periods. Always check the latest DES before investing.

Shariah compliance status changes as company financials change — always verify current DES status before investing. Indonesia’s 45% debt threshold differs from AAOIFI standards; investors applying stricter criteria should adjust accordingly.
