Overview
EFA and IEFA are both iShares ETFs tracking developed-market ex-U.S. equity exposure, but they differ in index choice and cost structure. The practical result is that IEFA offers wider diversification at a significantly lower fee.
How they differ
The most obvious difference is expense ratio: IEFA charges 0.07% versus 0.32% for EFA, a gap of 0.25%. That 25-basis-point annual saving compounds over decades. Second, IEFA's underlying index is broader—it includes small-cap stocks across developed markets outside the U.S. and Canada, whereas EFA focuses on large and mid-cap names. This structural difference means IEFA owns more companies and carries different sector and geographic tilts. Beta is nearly identical at 0.87 and 0.89, meaning systematic risk to developed-market downturns is comparable.
Who each is best for
- EFA: Investors who prefer the simplicity and historical track record of the original MSCI EAFE Index and have no strong preference for small-cap exposure; those who built positions years ago and see no reason to migrate.
- IEFA: Investors seeking broad developed-market ex-U.S. exposure at the lowest cost, particularly those beginning a new allocation or rebalancing an existing one; fits allocations that benefit from the small-cap inclusion and the fee efficiency.
- Currency headwind: Both ETFs hold foreign-currency-denominated securities; a strengthening U.S. dollar erodes returns for dollar-based investors, and neither fund hedges by default.
- Developed-market cyclicality: These funds track mature economies with aging demographics and lower expected long-term growth; economic recession or stagnation in Europe or Japan will weigh on both holdings similarly.
- Index overlap: While IEFA's small-cap inclusion creates a different return profile, it also maintains significant overlap with EFA's core holdings, so the two are not truly diversifying if held together.
Bottom line
If you prioritize low costs and broad diversification, IEFA's 0.07% expense ratio and small-cap inclusion offer clear structural advantages over EFA's higher fee. If you value simplicity and the longevity of a widely-replicated large-cap index, EFA remains a straightforward choice. Both track the same geographic exposure and distribute at comparable yields, so the decision hinges on cost, breadth, and fund size. Past performance does not predict future results.
