If you searched “how to buy Korean stocks from the US,” the answer changed completely in 2026. Until recently it was, effectively, “you mostly can’t.” Now three doors are open at once. Here’s each one, step by step — with the taxes, FX, and limits that decide which is yours. This is not financial advice.
The short answer: three doors
There are now three ways to put Korean equities in a US account: (1) SK Hynix’s Nasdaq ADR (ticker SKHY, debut targeted for July 10), (2) direct KRX access through Interactive Brokers, and (3) a US-listed Korea ETF such as EWY. They differ less in difficulty than in what you can actually buy — and at what hidden cost.
Background — why this was hard until now
Korea was long the developed market where a foreign individual found it hardest to buy in. A foreign investor registration system, introduced in 1992, meant opening an account required registering with Korea’s financial regulator first. That requirement was abolished on December 14, 2023 — after roughly 30 years — and omnibus accounts were allowed, which broke the dam. Everything in 2026 (Interactive Brokers’ KRX launch, and the SK Hynix ADR) flows from that redesign. So the real answer to “how to buy Korean stocks” isn’t “an ADR appeared” — it’s “the access structure was rebuilt for the first time in three decades.”
Door 1 — SK Hynix ADR (the easiest door)
The lowest-friction route: if your account trades US stocks, it can trade this.
- What: American Depositary Receipts for SK Hynix (KRX: 000660). Ticker SKHY, Nasdaq Global Select.
- Structure: 17.79 million new shares issued as ADRs, at a ratio of 1 common share = 10 ADRs. Based on the ₩2,555,000 reference price (June 23 close), one ADR works out to roughly $167 — final price set after bookbuilding.
- Size & use: up to ₩45.45 trillion (~$29.65 billion) raised — earmarked for next-generation process equipment, domestic capacity, and advanced packaging (i.e., HBM expansion). SK Hynix leads the HBM market with roughly a 60% share (estimates range 50–62%).
- The limit: it’s one stock. Perfect if you only want the SK Hynix thesis; zero exposure to any other Korean name.
- Check: underwriters BofA, Citi, Goldman Sachs, JPMorgan. Confirm final price and the listing date (July 10, tentative) right before the debut.

Door 2 — Direct KRX access (the widest door)
Since May 2026, Interactive Brokers offers direct trading in 2,700+ KRX-listed securities — the first major US broker to do it. The decisive difference from the ADR: not just Hynix, but the whole small- and mid-cap value chain is in scope.
- Upside: access to every listed name; you hold the underlying shares directly (no ADR fees or premium/discount gap).
- The checklist before you enable it:
- FX: you must convert to won — direct currency risk.
- Hours: KRX trades 09:00–15:30 KST — that’s evening-to-overnight on the US East Coast.
- Dividend tax: confirm the 15% treaty-rate procedure (see our dividend tax guide).
- Best for: readers hunting the names that haven’t reached US lists yet.
Door 3 — US-listed ETF (the lowest-effort door)
If you’d rather not touch accounts or FX at all, a US-listed Korea ETF like EWY remains.
- Upside: one click, in USD, just like any US stock.
- The trap: roughly half of EWY is Samsung Electronics + SK Hynix (see our piece on EWY concentration). It’s less “buy Korea” than “buy the memory duo” — fine, as long as you know it going in.
The three doors, side by side
| Door 1 · ADR (SKHY) | Door 2 · Direct (IBKR) | Door 3 · ETF (EWY) | |
|---|---|---|---|
| What you can buy | SKHY, one stock | 2,700+ KRX names | Index basket (~half in two stocks) |
| Difficulty | Same as any US stock | Medium (permissions, FX) | Same as any US stock |
| Currency | USD | KRW (direct FX risk) | USD (embedded FX risk) |
| Dividend tax | Withheld via ADR route | 15% treaty procedure | Handled at fund level |
| Best reader | Wants only the Hynix thesis | Value-chain hunter | One-click diversification |
Risk — look at the room, not the door
Three open doors mean you can buy — not that you should now.
- Volatility: the KOSPI plunged on June 23 (both big chipmakers off ~12%, tripping a circuit breaker) and again on July 2 (Samsung −9.1%, SK Hynix −14.5%, a sidecar). If your instincts are calibrated to US large-caps, this will catch you off guard.
- Dilution timing: SK Hynix is up around 340% this year and is printing 17.79 million new shares (a low-single-digit-percent dilution — verify against total shares) to list. A moment that’s optimal for the company to sell isn’t guaranteed to be optimal for the buyer.
- Cycle: memory is structurally boom-bust. The bull case is that HBM has flattened the cycle; the bear case is that it therefore snaps back harder. Both have grounds.
- Currency: won exposure doesn’t vanish — each door just changes its form.
🎩 Under the Gat — donghak gaemi — Korea’s retail army — read this listing the opposite way from how the US did. In the same week a US forum celebrated “we can finally buy it,” Korean forums were calculating dilution and overhang. Same event, two ledgers. Every door is still open tomorrow — watch the price, not the door.

Frequently Asked Questions
What account do I need to buy SK Hynix’s ADR (SKHY)?
Any US brokerage account that can trade Nasdaq-listed stocks. The ticker has been made public as SKHY; the final offer price is set after bookbuilding. Confirm the final price and the listing date (July 10, tentative) before the debut. This is not financial advice.
Can I buy other Korean stocks directly, not just SK Hynix?
Yes. Since May 2026, Interactive Brokers offers direct access to 2,700+ KRX-listed securities — the first major US broker to do so. That covers the small- and mid-cap names an ADR won’t, at the cost of FX conversion and Korean trading hours.
How are dividends taxed for a US investor holding Korean shares?
Korean dividend withholding is 22% by default, reducible to 15% under the US–Korea tax treaty (a procedure is required). Capital gains are generally exempt for small minority shareholders of listed stocks. See our dividend tax guide for details. Not tax advice.
Isn’t EWY enough to ‘own Korea’?
It can be, if broad exposure is your goal. Just understand the concentration — roughly half of EWY sits in Samsung Electronics and SK Hynix, so it’s closer to buying the memory duo than buying all of Korea.
Should I rush in before the SK Hynix ADR debut?
Three doors opening means you can buy — not that you must buy now. SK Hynix is up around 340% this year and is issuing new shares near record highs. Every door is still open tomorrow. Watch the price, not the door. This is not financial advice.
