EEM vs IEMG: Which Is the Better Pick in 2026?

Overview

EEM and IEMG are both BlackRock equity ETFs tracking emerging-markets indices, but they differ in scope and cost structure. EEM follows the narrower MSCI Emerging Markets Index (roughly 800 holdings), while IEMG tracks the broader MSCI Emerging Markets Investable Market Index (over 2,000 holdings). The practical upshot: IEMG casts a wider net across emerging economies and charges significantly less to do it.

How they differ

The biggest difference is fee structure. IEMG's expense ratio is 0.09% versus EEM's 0.72%—that's a 63-basis-point annual drag that compounds over time. IEMG also has $134 billion in assets under management compared to EEM's $25 billion, giving it deeper liquidity and lower trading costs.

The second difference is index methodology. EEM's MSCI Emerging Markets Index is a large- and mid-cap focused benchmark, while IEMG's Investable Market Index includes smaller companies, resulting in broader geographic and sectoral diversification. IEMG's yield of 2.42% is also 52 basis points higher than EEM's 1.90%, though this partly reflects the inclusion of smaller-cap dividend payers.

Both funds share similar market risk (beta near 0.95 and 0.93 respectively) and track essentially the same geographic exposure. The risk profiles are comparable; the real choice is between lower costs and broader diversification (IEMG) versus a more concentrated, cap-weighted core (EEM).

Who each is best for

EEM: Investors who want a simpler, more traditional large-cap emerging-markets core and don't mind paying higher fees for historical brand recognition or have existing positions they're reluctant to consolidate.

IEMG: Cost-conscious buy-and-hold investors seeking maximum diversification within emerging markets; ideal for tax-advantaged accounts where the fee savings compound over decades, or for those who value the broader index methodology and higher yield.

Key risks to know

• Index concentration: Both track cap-weighted indices with heavy exposure to China and financials; single-country or sector downturns can hit both simultaneously.

• Fee drag on EEM: The 0.72% expense ratio means EEM must outperform IEMG by roughly 63 basis points annually just to break even—a structural headwind unlikely to be offset by performance.

• Emerging-market currency risk: Both funds hold foreign-currency assets; significant dollar strength can erode returns regardless of underlying market performance.

• Smaller-cap liquidity in IEMG: The broader index includes less liquid holdings; during market stress, wider bid-ask spreads may emerge.

Bottom line

If you prioritize low costs and broad diversification, IEMG's 0.09% expense ratio and 2,000-plus holdings make it the more efficient core emerging-markets holding. If you prefer simplicity and a tighter large-cap focus, EEM remains viable, though you'll pay substantially more for the privilege. Past performance of either fund doesn't predict future emerging-market returns.
