Quick Summary
- IEMG tracks the MSCI Emerging Markets Investable Market Index — over 2,700 holdings across 24 countries
- Expense ratio: 0.09% — among the cheapest ways to access emerging markets
- Top country exposures: China (~25%), India (~22%), Taiwan (~18%), South Korea (~12%)

Bottom line: IEMG is the most cost-efficient way to add broad emerging markets exposure to a portfolio. It’s a core holding for globally diversified investors — but understand the volatility before buying.
If you’re building a globally diversified portfolio, you can’t ignore emerging markets. Countries like India, China, Brazil, and South Korea represent a growing share of world GDP — and their equity markets offer growth potential that developed markets often can’t match. The iShares Core MSCI Emerging Markets ETF (ticker: IEMG) is one of the most popular and cost-effective ways to get that exposure. Here’s everything you need to know in this IEMG ETF review.
What Is IEMG?
IEMG is an exchange-traded fund issued by BlackRock’s iShares division, first launched in 2012. It tracks the MSCI Emerging Markets Investable Market Index, which captures large, mid, and small-cap equities across 24 emerging market countries. With over $75 billion in assets under management, it’s one of the largest emerging markets ETFs available.
What Does IEMG Hold?
IEMG holds more than 2,700 individual securities, making it one of the broadest emerging markets funds available. No single stock dominates — the fund is well-diversified across holdings.
Top Country Allocations (approximate, as of early 2026):
- China: ~25%
- India: ~22%
- Taiwan: ~18%
- South Korea: ~12%
- Brazil: ~5%
- Saudi Arabia: ~4%
- Other EM countries: ~14%
Top Holdings by Stock:
- Taiwan Semiconductor Manufacturing (TSMC)
- Samsung Electronics
- Tencent Holdings
- Alibaba Group
- Infosys
Technology and financial services dominate the sector breakdown, together accounting for roughly 45% of the portfolio. Consumer discretionary, communication services, and materials round out the top sectors.
IEMG Expense Ratio: The Cost Advantage
IEMG charges an expense ratio of 0.09% annually — that’s $9 per year on a $10,000 investment. This is substantially cheaper than the original iShares Emerging Markets ETF (EEM), which charges 0.70%. The difference compounds significantly over time: over 20 years, EEM’s higher fees can reduce your returns by several percentage points in total.
Among major emerging markets ETFs, IEMG competes closely with Vanguard’s VWO (0.08%) and Schwab’s SCHE (0.11%). All three are near-equivalent in cost; your choice among them should come down to index methodology and existing brokerage relationships.
Performance History
Emerging markets are inherently more volatile than developed market equities. IEMG has reflected this reality:
- 2017: Exceptional year, +37% return
- 2018: Down ~14% as dollar strengthened and trade tensions rose
- 2020: Strong recovery, +18%
- 2022: Difficult year, down significantly amid China regulatory crackdowns and global rate hikes
- 2023–2025: Recovery and growth driven by India’s continued expansion and semiconductor demand
Over a 10-year horizon, IEMG has delivered mid-single-digit annualized returns — lower than U.S. large-cap indexes like SPY over the same period, but with the potential for higher long-term gains as emerging economies mature and middle classes expand. The case for EM is a long-term thesis, not a short-term trade.
Risk Profile: What You’re Taking On
IEMG comes with risks that domestic ETFs don’t carry:
- Currency risk: Returns are affected by exchange rate fluctuations between the U.S. dollar and EM currencies
- Political/regulatory risk: China’s government intervention in tech sectors in 2021 is a prime example of how policy changes can crater individual holdings
- Geopolitical risk: Taiwan’s political situation creates tail risk for a significant portion of the portfolio
- Liquidity risk: Smaller EM markets may have less liquid underlying securities
- Accounting standards: Disclosure and governance standards vary across countries
These aren’t reasons to avoid IEMG — they’re reasons to size your position appropriately. Most financial advisors suggest an EM allocation of 5–15% of an equity portfolio for investors with 15+ year horizons.
IEMG vs. EEM: Why IEMG Usually Wins
The older iShares Emerging Markets ETF (EEM) covers similar ground but charges 0.70% — nearly 8x the cost. IEMG also holds small and mid-cap stocks (the “IMI” — Investable Market Index expansion) that EEM excludes, providing broader diversification. For long-term investors, IEMG is almost always the better choice between the two.
Who Should Own IEMG?
IEMG is a good fit if you:
- Have a long-term investment horizon (10+ years)
- Want geographic diversification beyond the U.S. and developed markets
- Believe in the long-term growth story of India, Southeast Asia, and other emerging economies
- Can tolerate 20–30% drawdowns without panic-selling
- Are looking for a low-cost, single-fund solution for EM exposure
It’s a poor fit for:
- Short-term traders or investors with a time horizon under 5 years
- Retirees or near-retirees who can’t afford significant volatility
- Investors heavily concentrated in China-specific risks who want a more targeted allocation
Final Verdict
The IEMG ETF earns its place as one of the top emerging markets funds available. With a 0.09% expense ratio, 2,700+ holdings, and broad geographic diversification, it’s the most efficient way for U.S. investors to add emerging market exposure to a long-term portfolio. The volatility is real, but so is the opportunity — for patient investors, IEMG is a core building block worth owning.
