What Is EWY? iShares MSCI South Korea ETF
Last updated September 2026
Short answer
EWY is iShares MSCI South Korea ETF, an ETF that tracks the MSCI Korea Index at a 0.59% expense ratio. EWY holds South Korean equities, and the single most important fact about it is concentration: SK Hynix at about 27.2% and Samsung Electronics at about 23.2% together account for roughly 50.4% of the fund. Buying EWY is not really buying South Korea. It is buying two memory-semiconductor manufacturers with a diversified Korean portfolio attached, and that distinction should drive the decision.
EWY is issued by iShares and tracks the MSCI Korea Index. It charges a 0.59% expense ratio, holds approximately $24.5B in assets under management, yields about 1.01%, and launched in 2000.
Half the fund is two companies
SK Hynix 27.2%, Samsung Electronics 23.2%. Together 50.4%. Behind them the weights drop off sharply, to roughly 4.3%, 3.6% and 1.7% for the next three holdings.
Country funds are often assumed to provide diversified exposure to an economy. This one does not, because the Korean market itself is dominated by a small number of very large industrial groups. Technology is 61% of the fund, industrials 15% and financials 9%.
The practical consequence: EWY tracks the memory-semiconductor cycle at least as closely as it tracks the Korean economy. In a memory downturn it will fall regardless of how Korean consumer demand or construction is performing.
The risks that do not exist in a developed-market fund
Currency: the fund holds won-denominated shares and reports in dollars, so a stronger dollar reduces its value independently of the underlying businesses.
Geopolitics: South Korea's security situation carries tail risk that is very hard to price and has no equivalent in most developed-market exposure. It rarely affects prices and would matter enormously if it did.
Single-country concentration: with no diversification across economies, a domestic policy change, a chaebol governance event, or a trade dispute affects the entire holding at once.

FAQ
What is EWY?
+
EWY is the iShares MSCI South Korea ETF. It tracks the MSCI Korea Index, holding large and mid-cap South Korean companies. It charges 0.59%, holds about $24.5B, yields roughly 1.01%, and launched in 2000.
How concentrated is EWY?
+
Exceptionally. SK Hynix at about 27.2% and Samsung Electronics at about 23.2% are roughly 50.4% of the fund between them. The next largest holding is around 4.3%. This is closer to a two-stock position with a Korean portfolio attached than to diversified country exposure.
Is EWY a bet on South Korea or on semiconductors?
+
Substantially on semiconductors. Technology is 61% of the fund and the two largest holdings are memory manufacturers. It will follow the memory chip cycle at least as closely as it follows Korean economic conditions.
What are the risks specific to EWY?
+
Three that a developed-market fund does not carry in the same way: currency, since won-denominated holdings are reported in dollars; geopolitical tail risk from the security situation on the peninsula; and single-country concentration, where one domestic policy change affects everything you hold.
Is 0.59% expensive?
+
It is typical for a single-country emerging or developed-Asia fund and expensive relative to broad international exposure at 0.03-0.04%. Single-country funds cost more to run, and you are also paying for a much narrower proposition.
Does EWY pay a dividend?
+
About 1.01%. Korean corporate payout ratios have historically been low by international standards, though governance reforms have pushed in the direction of higher distributions. It is not an income holding.
How does EWY fit with a broad emerging-markets fund?
+
Most emerging-markets funds already hold Samsung and SK Hynix among their largest positions, so adding EWY concentrates further into companies you likely already own. It is a deliberate country and industry overweight rather than a way to add breadth.
What would hurt EWY most?
+
A memory-semiconductor downturn, given the two largest holdings, or a sharp strengthening of the dollar against the won. Both can happen without anything changing in the broader Korean economy.
What is EWY's expense ratio?
+
EWY has an expense ratio of 0.59% per year as of August 2026, charged by iShares and deducted from the fund's value rather than billed to you separately. On a $10,000 position that is roughly $59 a year. Fees compound over time, so on a long-term holding the expense ratio is one of the few return drivers you control. It is worth comparing against other funds that track the MSCI Korea Index before you choose.
How do I compare EWY to similar ETFs?
+
Put a few fields side by side: the expense ratio (fees compound over decades), the index or strategy it tracks, the top holdings and how much they overlap with what you already own, the dividend yield, and the AUM, liquidity, and bid-ask spread that affect trading costs. For index funds, tracking error (how closely it follows its index) and tax efficiency matter too. EWY's figures are above; the full method is in Walnut's guide on how to compare ETFs.
