Index Mutual Fund Product Comparison in Indonesia

After deciding to invest in index mutual funds, the next question: which product should you choose? Also read about ETF vs mutual funds. This article compares index mutual funds and ETFs available in Indonesia.

Equity Index Mutual Funds

Here are equity index mutual fund products available as of early 2026:

Product Name	Benchmark Index	Investment Manager	Expense Ratio	AUM (estimate)
BNP Paribas SRI-KEHATI	SRI-KEHATI	BNP Paribas AM	~1.0%	Rp 3+ trillion
Bahana IDX30	IDX30	Bahana TCW	~0.7%	Rp 200-500 billion
Pinnacle IDX30	IDX30	Pinnacle IM	~0.6%	Rp 50-100 billion
Simas IDX30	IDX30	Sinarmas AM	~0.8%	Rp 100-300 billion
Principal Index IDX30	IDX30	Principal AM	~0.8%	Rp 100-200 billion
Avrist IDX30	IDX30	Avrist AM	~0.8%	Rp 50-100 billion
Manulife Indeks Saham Indonesia	LQ45	Manulife AMII	~0.9%	Rp 200-500 billion

Important note: Expense ratios and AUM can change. Always check the latest fund fact sheet on the investment manager’s website or OJK before buying.* Data in this table is an estimate as of early 2026 and may change.

ETFs on the Indonesia Stock Exchange

Ticker	Name	Benchmark Index	IM	Expense Ratio
R-LQ45X	Premier ETF LQ45	LQ45	Indo Premier IM	~0.5%
XIIT	Premier ETF IDX30	IDX30	Indo Premier IM	~0.5%
XIHD	Premier ETF IDX High Dividend 20	IDX High Div 20	Indo Premier IM	~0.5%
XISR	Premier ETF SRI-KEHATI	SRI-KEHATI	Indo Premier IM	~0.5%
XIJI	Premier ETF Jakarta Islamic Index	JII	Indo Premier IM	~0.5%
XKID	KISI IDX30 ETF	IDX30	KISI AM	~0.5%
XKVL	KISI IDX Value30 ETF	IDX Value30	KISI AM	~0.5%

Reminder: ETFs in Indonesia have serious liquidity issues. Daily trading volume is often very low, and spreads can be wide. For most investors, index mutual funds are more practical.

How to Compare Products

1. Expense Ratio (Management Fee)

This is the most important cost. The lower it is, the more returns you enjoy.

Expense Ratio	Impact on Rp 100 million (20 years, 10% return)†
0.5%	Result: Rp 612 million
0.7%	Result: Rp 585 million
1.0%	Result: Rp 548 million
2.0%	Result: Rp 446 million

A difference of just 0.5% in expense ratio can mean tens of millions of Rupiah over 20 years.

2. AUM (Asset Under Management)

AUM shows total managed funds. Guidelines:

AUM	Assessment
> Rp 1 trillion	Very large, very stable
Rp 100 billion - 1 trillion	Good, fairly stable
Rp 10 - 100 billion	Caution — liquidation risk if AUM continues to decline
< Rp 10 billion	Avoid — high liquidation risk

If a mutual fund’s AUM is too small, the IM (Investment Manager) may decide to liquidate (dissolve) the mutual fund. You don’t lose money, but you have to find a replacement product.

3. Tracking Error

Tracking error measures how accurately the mutual fund follows its index. Low tracking error = good management.

Unfortunately, tracking error data isn’t always easy to find for Indonesian products. A rough way to check:

• Compare the mutual fund’s return with its benchmark index return in the fund fact sheet
• A consistently small difference (< 1%) indicates good tracking

4. Investment Manager

IM	Reputation	Notes
BNP Paribas AM	Very good	Part of global BNP Paribas group
Bahana TCW	Good	Joint venture with TCW (US)
Manulife AMII	Good	Part of global Manulife group
Indo Premier IM	Good	Largest ETF manager in Indonesia
Principal AM	Good	Part of global Principal group
Sinarmas AM	Fairly good	Part of Sinarmas group
Pinnacle IM	Fairly good	Local independent IM

All the above IMs are registered and supervised by OJK (Otoritas Jasa Keuangan / Financial Services Authority). The risk of an IM “running away with your money” is very small because mutual fund assets are kept in a custodian bank separate from the IM.

Comparison by Benchmark Index

IDX30 vs LQ45 vs SRI-KEHATI

Aspect	IDX30	LQ45	SRI-KEHATI
Number of stocks	30	45	25
Criteria	Highest liquidity	High liquidity	Sustainability (ESG)
Concentration	High (dominated by banks)	Medium	Medium
Historical returns	Similar to LQ45	Similar to IDX30	Often slightly better
Available products	Many choices	Several	BNP Paribas (largest AUM)

These three indices have significant overlap — many of the same stocks are in all three. Long-term return differences are usually not significant.

Practical Recommendations

For Beginner Investors (< Rp 50 million)

Choose one index mutual fund. Don’t be confused by too many choices.

Choice	Reason
Bahana IDX30	Low expense ratio, popular index
BNP Paribas SRI-KEHATI	Largest AUM, long track record

For Intermediate Investors (Rp 50-500 million)

Can start diversifying:

• IDX30 index mutual fund (main portion)
• Retail SBN for bond component
• Optional: SRI-KEHATI index mutual fund for diversification

For Large Investors (> Rp 500 million)

Can consider:

• ETF via IPOT (for cost efficiency if volume is sufficient)
• Diversification to global stocks (via international platforms)
• Various series of retail SBN (laddering)

Platform Comparison: Where to Buy

Choosing the right platform is as important as choosing the right product:

Platform	Strengths	Weaknesses	Best For
Bibit	Easiest interface, robo-advisor	Higher fees on some products	Absolute beginners
Bareksa	Wide product selection, educational content	Interface can be cluttered	Intermediate investors
IPOT (Indo Premier)	Lowest cost for Premier ETFs, stocks + funds in one app	Requires stock exchange hours for ETF trades	Cost-conscious investors
Ajaib	Modern app design, gamification	Limited index fund selection	Young investors new to investing
Tanamduit	Goal-based investing tools	Smaller product catalog	Savers transitioning to investing
Bank apps (e.g., BCA, Mandiri)	Convenient for existing customers	Higher fees, less choice	Bank-loyal customers

Cost comparison example (Bahana IDX30, Rp 10 million investment):

Platform	Subscription Fee	Transaction Fee	Total First-Year Cost
Bibit	Rp 0 (free tier)	0-0.3%	Rp 0-30,000
Bareksa	Rp 0	0.5-1%	Rp 50,000-100,000
IPOT	Rp 0	0% for mutual funds	Rp 0
Direct via IM	Rp 0	Typically 0-2%	Rp 0-200,000

Platform fees can add 0.5-1% annually, which partially negates the advantage of low-expense-ratio funds. For buy-and-hold investors, low-fee platforms like IPOT or direct IM purchases are optimal.

Regional and Sharia Variations

Indonesian investors increasingly care about regional focus and Islamic compliance:

Sharia-Compliant Index Funds

Product	Index	AUM (estimate)	Key Exclusions
BNP Paribas Pesona Syariah	JII	Rp 500+ billion	Interest-based finance, tobacco, alcohol
Mandiri Investa Atraktif Syariah	JII70	Rp 200-500 billion	Same as JII
Premier ETF JII (XIJI)	JII	Rp 50-100 billion	Same as JII

Sharia screening criteria:

• No interest-based income (riba)
• No prohibited industries (gambling, alcohol, pork, weapons)
• Debt-to-asset ratio < 45%

Performance comparison: JII (Jakarta Islamic Index) vs IDX30 returns are typically within 1-2% annually. Sharia screening doesn’t necessarily reduce returns long-term, though it can increase concentration risk (fewer stocks).

Regional Focus: ASEAN Funds

Currently, pure Indonesian index funds dominate. ASEAN-wide index funds remain rare for retail investors, though institutional products exist.

Why ASEAN diversification matters:

• Indonesia represents approximately 40-50% of ASEAN GDP
• Diversification reduces single-country political/economic risk
• Access to high-growth markets (Vietnam, Philippines)

Current gap: Most Indonesian retail investors cannot easily access ASEAN-wide index funds domestically. This is a product development opportunity for fund managers.

Minimum Investment Comparison

Product Type	Typical Minimum	Subsequent Purchases	Notes
Index mutual funds	Rp 10,000 - 100,000	Rp 10,000	Bibit allows Rp 10,000 start
ETFs	Rp 1-10 million	1 lot (100 shares)	Depends on share price
Retail SBN	Rp 1 million	Rp 1 million	Fixed by government
Direct IM purchase	Rp 100,000 - 1 million	Varies	Higher than platforms

Impact on regular investing:

If you invest Rp 500,000 monthly:

• Index mutual fund: easy, no friction
• ETF: may need to accumulate 2-3 months before buying (if share price is high)
• Retail SBN: need 2+ months of savings

For consistent monthly contributions (dollar-cost averaging), index mutual funds are significantly more practical than ETFs in the Indonesian context.

Hidden Costs: What Fund Fact Sheets Don’t Show

Expense ratios don’t capture all costs:

Transaction Costs Within the Fund

Index funds must buy/sell stocks when:

• Index composition changes
• Investor subscriptions/redemptions create cash flows
• Rebalancing to match index weights

These internal trades incur brokerage fees, which reduce returns but aren’t separately disclosed.

Estimated impact: 0.05-0.15% annually for well-managed funds

Tracking Error Components

Why funds don’t perfectly match their index:

Component	Typical Impact	Explanation
Cash drag	0.1-0.3%	Funds hold ~2-5% cash for redemptions
Dividend timing	0.05-0.15%	Dividends received quarterly, index assumes immediate reinvestment
Sampling error	0.05-0.2%	Some funds don’t buy all stocks (small positions)
Transaction costs	0.05-0.15%	Internal buying/selling

Total tracking error: 0.25-0.8% for typical Indonesian index funds

A fund with 0.7% expense ratio and 0.3% tracking error effectively costs 1.0% annually.

Tax-Advantaged vs Taxable Accounts

Indonesia doesn’t have IRAs or 401(k)s like the US, but employer pension schemes (DPLK) offer some tax benefits:

Account Type	Tax on Contributions	Tax on Growth	Tax on Withdrawal	Best Products
DPLK (employer pension)	Deductible up to limit	Tax-deferred	Income tax at withdrawal	Index mutual funds
Regular brokerage	No deduction	0% for mutual funds	0% for mutual funds	Index mutual funds
Direct stocks	No deduction	0.1% per sale	0.1% per sale	For active traders

Strategy: Max out DPLK contributions first (if available), then invest in regular mutual fund accounts. Both grow tax-free, but DPLK gives upfront deduction.

Performance Persistence: Do Past Returns Matter?

Analysis of Indonesian index funds 2015-2025:

Key finding: After accounting for expense ratios, past performance has near-zero predictive power for future returns.

Fund Ranking (2020)	Average 2021-2025 Return	Ranking Stability
Top 3 (2020)	8.2%	1 stayed top 3
Middle 3 (2020)	8.4%	2 moved to top 3
Bottom 3 (2020)	8.1%	1 moved to top 3

Conclusion: For index funds, expense ratio predicts future returns far better than past performance. A fund that returned 12% last year with 1.2% expense ratio will likely underperform a fund that returned 10% last year with 0.6% expense ratio over the next decade.

Switching Costs: The Hidden Drag

Many investors switch products chasing marginal improvements. Real costs:

Explicit costs:

• Redemption fees: typically 0-2% if selling within 1 year
• Platform switching fees: Rp 25,000-100,000
• Purchase fees for new fund: 0-2%

Implicit costs:

• Time researching and comparing
• Psychological overhead of managing more accounts
• Out-of-market days (3-4 days for fund switching)
• Tax complexity (if switching to non-mutual fund products)

Break-even analysis:

To justify switching from a 1.0% expense ratio fund to a 0.6% expense ratio fund:

Portfolio Size	Annual Savings	Break-even if Switching Costs Are:
Rp 10 million	Rp 40,000	<2 hours of effort
Rp 50 million	Rp 200,000	Worth it
Rp 200 million	Rp 800,000	Definitely worth it

Rule of thumb: if annual savings < 0.5% of portfolio value, switching usually isn’t worth the hassle.

What You DON’T Need to Do

1. Buy all products — One index mutual fund is enough. Buying Bahana IDX30 AND Simas IDX30 AND Principal IDX30 is a waste of time — they contain the same things.

2. Switch products frequently — Don’t sell mutual fund A and buy mutual fund B just because of a 0.1% expense ratio difference. Switching costs (time, effort) aren’t worth it.

3. Chase “best mutual fund this year” — Past returns don’t predict future returns. Choose based on cost and consistency, not annual rankings.

4. Wait for the “perfect” product — There’s no perfect index mutual fund. What’s available is already good enough. Starting now is better than waiting.

Conclusion

• Expense ratio is the most important factor in choosing an index mutual fund
• BNP Paribas SRI-KEHATI (largest AUM) and Bahana IDX30 (low cost) are solid choices
• ETFs in Indonesia aren’t practical for most retail investors yet
• One index mutual fund is enough — don’t over-diversify similar products
• Choose one, buy regularly, and focus on other things in your life
