The iShares MSCI EAFE ETF (NYSEARCA:EFA) has been the default one-ticker way to own developed markets outside the US and Canada for more than two decades. Investors hold EFA for its familiar MSCI EAFE benchmark, deep options market, and roughly $75.6 billion in net assets. With EFA up 10.27% year to date and 20.71% over the past year, international exposure is finally pulling its weight in 2026. The problem is that iShares itself already sells a nearly identical fund at a fraction of the cost, and the gap compounds every year the position sits in a portfolio.
That fund is the iShares Core MSCI EAFE ETF (CBOE:IEFA), part of BlackRock’s “Core” lineup launched in October 2012 to give buy-and-hold investors cheaper building blocks.
Why EFA Still Draws Money
The MSCI EAFE Index is what this one tracks, a large- and mid-cap benchmark covering 21 developed markets across Europe, Australasia, and the Far East. Top positions include ASML Holding at 2.58% of assets, followed by HSBC, AstraZeneca, Roche, and Shell. The 710-position portfolio leans heavily on European banks, energy majors, and pharma, the classic dividend-paying international core. EFA’s developed-market focus makes it a staple for international diversification.
The fund’s real moat is trading infrastructure. EFA options are among the most liquid in the ETF market, which is why institutional desks, covered-call writers, and tactical hedgers keep it as their working position. For those uses, the ticker itself has value.
The Fee Gap Is the Whole Argument
The expense ratio on this one is 0.32%. Over on the same issuer’s shelf, IEFA charges just 0.07%. That is a 25-basis-point gap, or roughly 78% less in annual fees. On a $100,000 position, the holder of IEFA keeps $250 more per year before any compounding. Over a decade at similar returns, the drag on EFA compounds into meaningful money.
Performance data supports the “same exposure” framing rather than an outright win for either fund. Year to date, IEFA is up 10.29% against EFA’s 10.27%. Over one year, EFA edges IEFA 20.71% to 20.47%, reflecting index construction and securities-lending differences rather than a durable EFA advantage. Over 10 years, IEFA has returned 148.11% versus EFA’s 145.66%, consistent with the fee differential accruing over time.
Broader Index, Higher Yield
The MSCI EAFE IMI tracks this index, which adds small caps to the same large- and mid-cap universe EFA holds. The fund reports 2,639 positions against EFA’s 710, and holdings such as WiseTech Global, Cellnex Telecom, and Mycronic show up in IEFA but not EFA. This is a slightly broader slice of the same developed-markets asset class. IEFA’s small-cap inclusion gives it a bit more reach than its older counterpart.
The income profile also favors IEFA. Its trailing dividend yield sits at 3.43% against EFA’s 3.2%. Investors get more yield and pay less in fees.
Asset flows tell the same story. IEFA has grown to $180.7 billion in net assets, more than double EFA, despite launching more than a decade later.
Who Should Stick With EFA
Options traders and short-term tactical users have a legitimate reason to stay. EFA’s options chain is deeper, spreads are tighter, and open interest supports large hedges. IEFA options exist but do not match that liquidity. Investors running covered calls, protective puts, or spread strategies against their international sleeve are paying the 25 basis points for a functioning derivatives market.
The other consideration is taxes. In a taxable account, swapping EFA for IEFA can trigger capital gains on years of appreciation. The fee savings compound, but so does a tax bill paid today.
Making the Swap Cleanly
In tax-advantaged accounts, the mechanics are straightforward: selling EFA and buying IEFA produces roughly one-for-one exposure. In taxable accounts, new contributions can go to IEFA while the EFA position is held or trimmed against realized losses elsewhere. Investors using EFA purely for options can keep the derivatives book on EFA and shift the underlying long exposure to IEFA.
What to Do With This
It remains a functional fund, but EFA is an older, more expensive version of what the same issuer now sells for a quarter of the price, with a broader index and a slightly higher yield. For a long-term holder of developed markets, IEFA captures nearly the entire purpose of EFA at 0.07% versus 0.32%, and the case for staying rests almost entirely on whether the options market matters to the position.
