This complete guide explains how to buy Korean stocks directly on the KRX — written from Seoul, inside Korea’s capital markets industry.
If you’ve read my earlier posts on Korean ADRs, you already know the limitation: only a handful of Korean companies trade in the US. Samsung Electronics trades as an illiquid OTC ticker. SK Hynix only recently got a proper US listing. And the names generating the most excitement in Seoul right now — the defense stocks, the K-beauty names, the KOSDAQ biotech runners — have no US listing at all.
If you want those, you need to buy them where Koreans buy them: directly on the Korea Exchange (KRX).
The good news? This just got dramatically easier. In May 2026, Interactive Brokers became the first major US-based broker to offer seamless, direct KRX trading. Combined with Charles Schwab’s long-standing Global Account, US investors now have two solid routes onto the KRX without ever setting foot in Korea or registering with Korean regulators themselves.
I’m writing this from Seoul, where I work inside the Korean capital markets industry. Below is the guide I wish existed in English: exactly which brokers work, exactly how to open the account, what it costs, when you can trade, and how the taxes shake out.
Quick Answer (TL;DR)
Two US brokers give you direct access to KOSPI and KOSDAQ stocks:
| Interactive Brokers (IBKR) | Charles Schwab Global Account | |
|---|---|---|
| KRX access since | May 2026 (newest, most complete) | Long-standing (one of 12 global markets) |
| Account opening | Fully online, ~1 business day | Online/PDF application, linked to Schwab One, 1–3 days |
| Currency | Multi-currency incl. KRW | Trades settle in KRW |
| FX conversion cost | From 0.20 bps (0.0020%) — institutional spreads | Built into conversion rate (wider) |
| Margin on Korean stocks | Portfolio margining where applicable | No margin, no shorting, no options |
| API / algo trading | Yes | No |
| Best for | Active traders, larger positions, automation | Existing Schwab customers, buy-and-hold |
If you don’t already have a Schwab relationship, IBKR is the stronger choice in 2026 — better FX pricing, more securities, API access, and same-day permission enablement for existing clients.
Why Buy Korean Stocks Directly on the KRX instead of ADRs (For Some Investors)
Before the how-to, a quick reality check on when direct access is actually worth it:
Direct KRX access makes sense if you want:
- Stocks with no ADR. Hanwha Aerospace, HD Hyundai Heavy Industries, Ecopro BM, Alteogen, KakaoBank, most of KOSDAQ — none of these have US listings. Direct access is the only way to own them.
- Local pricing. ADRs frequently trade at premiums or discounts to the underlying Korean shares, especially in volatile weeks. On the KRX you get the same price Korean institutions get.
- Full market breadth. IBKR alone gives access to more than 2,700 KRX-listed securities. The ADR universe is maybe two dozen names.
- Liquidity where it actually lives. Korean stocks trade most actively in their home market — KRX turns over more than $10 billion per day.
Stick with ADRs or ETFs (EWY, FLKR) if:
- You’re making a small, one-time purchase of a mega-cap that has a US listing anyway
- You don’t want any KRW currency exposure mechanics
- You can’t (or don’t want to) trade during Korean market hours — roughly 7:00 PM to 1:30 AM US Eastern
Still with me? Let’s open an account.
Route 1: Interactive Brokers (The 2026 Game-Changer)
What happened in May 2026
On May 7, 2026, Interactive Brokers launched direct access to equities listed on the Korea Exchange — the first major US-based broker to do so. The launch covers 2,700+ listed securities across KOSPI and KOSDAQ, with real-time execution and institutional-grade pricing. In late June 2026, IBKR went further and added Nextrade (NXT), Korea’s new alternative trading system, which extends the tradable window beyond regular KRX hours.
For US retail investors, this is the single biggest improvement in Korea market access in years. Here’s how to get set up.
Step 1: Open an IBKR account (new clients)
If you don’t have an IBKR account yet:
- Go to interactivebrokers.com and click Open Account.
- Choose Individual (or Joint/IRA as appropriate — note that IRA availability for foreign-market trading has restrictions; call IBKR if you plan to hold Korean stocks in a retirement account).
- Complete the online application. You’ll need:
- Social Security Number (SSN) or ITIN
- Government-issued ID (driver’s license or passport)
- Employment and income information
- Investment experience questionnaire (be accurate — your answers determine which products you’re approved for)
- Choose IBKR Pro or IBKR Lite. For international trading, IBKR Pro is the account type you want — Lite is US-focused.
- Fund the account. ACH transfer from a US bank is free and takes 1–4 business days; wire transfers post same-day.
Most new-account approvals complete within one business day.
Step 2: Enable KRX trading permissions (the step everyone misses)
Having an IBKR account does not automatically mean you can trade Korean stocks. You need to switch on the market permission:
- Log in to Client Portal (the web dashboard, not the trading platform).
- Click the head-and-shoulders profile icon (top right) → Settings.
- Under Account Settings, find Trading Experience & Permissions.
- Click Stocks → Add/Edit.
- In the country/region list, check Asia-Pacific → South Korea (KRX).
- Agree to the risk disclosures and submit.
For existing clients, KRX enablement is same-day — often within minutes. New permission requests occasionally require you to update your investment-experience profile first (IBKR wants to see some stated experience with foreign equities).
Step 3: Subscribe to Korean market data (optional but recommended)
Without a data subscription you’ll see delayed quotes. To get real-time KRX prices:
- Client Portal → Settings → User Settings → Market Data Subscriptions.
- Search for Korea Exchange (KRX) under Asia-Pacific listings.
- Subscribe (there’s a modest monthly fee, typically in the single-digit USD range for non-professional users; it’s often waived or offset if you generate enough commissions).
You can absolutely trade with delayed data using limit orders — many buy-and-hold investors skip this fee entirely.
Step 4: Convert USD to KRW
Korean stocks settle in Korean won. Two ways to handle this on IBKR:
Option A — Manual conversion (cheapest, my recommendation):
- In Trader Workstation (TWS) or Client Portal, open the FX / Currency Conversion tool.
- Trade the USD.KRW pair: sell USD, buy KRW for the amount you plan to invest.
- IBKR’s FX conversion commissions start as low as 0.20 basis points (0.0020% of trade value) — this is institutional-grade pricing that no other retail route to Korea matches. Compare that to the 0.5–1.0%+ spread baked into most brokers’ automatic conversions.
Option B — Let IBKR borrow/auto-convert: You can place a Korean stock order with a USD balance and IBKR handles the currency, but depending on your account configuration this can create a small margin loan in KRW. Cleaner to convert first.
Step 5: Find the ticker and place your trade
Korean stocks use 6-digit numeric codes, not letters:
In TWS or the IBKR mobile app:
| Company | KRX Code |
|---|---|
| Samsung Electronics | 005930 |
| SK Hynix | 000660 |
| Hyundai Motor | 005380 |
| Hanwha Aerospace | 012450 |
| KakaoBank | 323410 |
- Type the 6-digit code or company name, select the listing on KRX (or KSE, as it may display).
- Use limit orders. Korean stocks have designated tick sizes and daily price limits of ±30% — market orders in fast conditions can fill badly.
- Note the board lot: most KRX stocks trade in single-share increments, so you can buy 1 share of anything.
Your order routes to Seoul in real time during Korean market hours. With IBKR’s Nextrade access, eligible stocks can also trade in extended sessions outside the main 9:00 AM – 3:30 PM KST window.
IBKR costs summary
- Commissions: IBKR publishes a tiered/fixed commission schedule for the Korea Stock Exchange on its fees page — low basis-point pricing consistent with its other Asian markets (check the live schedule at interactivebrokers.com, as tiers depend on your monthly volume).
- FX: from 0.20 bps + small minimum per conversion.
- Korean transaction tax: Korea levies a securities transaction tax on the sell side (a fraction of a percent, deducted automatically at execution — you’ll see it itemized on your trade confirmation).
- No custody fee, no account minimum, no inactivity fee.
One quirk worth knowing: KRX access through IBKR is not available to residents of Korea (or clients of IBKR’s Japan and India entities). US residents are fully eligible.
Route 2: Charles Schwab Global Account
Schwab has quietly offered direct Korea trading for years as part of its Global Account, which covers 12 foreign markets traded in local currency. If you already bank or invest with Schwab, this route means zero new institutions in your life.
How the account structure works
The key thing to understand: the Global Account is a separate account that must be linked to a Schwab One brokerage account. You can’t hold a Global Account by itself.
- Already have Schwab One? You just add the Global Account.
- New to Schwab? You can open both simultaneously.
The Global Account is limited to individual and joint registrations — no LLCs, no corporate accounts (trusts are case-by-case exceptions).
Step-by-step: opening the Schwab Global Account
- Log in to Schwab.com with your existing credentials (or open a Schwab One account first — standard online application with SSN, ID, and funding).
- Navigate to the Global Trading section (schwab.com/global-trading) and select Open a Schwab Global Account. Schwab uses a dedicated application for this account type — in some cases a downloadable form rather than a fully digital flow. If anything is unclear, their Global Investing Specialists at 800-992-4685 are genuinely useful and pick up quickly.
- Complete the application — it’s short since Schwab already has your KYC information. Approval typically takes 1–3 business days.
- Fund the Global Account by journaling cash from your linked Schwab One account (instant once the account is open).
- Convert USD → KRW. Within the Global Account interface, you convert currency before or at the time of the trade. You can hold KRW cash balances in the account (note: foreign currency balances earn no interest).
- Search by local ticker — Schwab uses the format
005930on the Korea market selection — get a real-time quote during Korean market hours, and place your limit order.
Schwab Global Account rules and limitations (important)
These are hard rules of the account, straight from the account agreement:
- Cash only. No margin, no short selling, no options in the Global Account. Every purchase requires cleared, converted funds before the order processes.
- No interest on cash balances in any currency.
- Trades execute in KRW during Korean market hours; commissions are charged as a fixed amount in the local currency (check Schwab’s Global Account pricing page for the current KRW commission schedule — the USD equivalent floats with the exchange rate).
- Some recent IPOs and certain preferred shares can be restricted for foreign accounts.
Who should choose Schwab over IBKR?
Honestly, the main argument is consolidation: if your entire financial life is at Schwab, adding one linked account beats onboarding at a new broker. Schwab’s phone support for global trading is also more hand-holding than IBKR’s, which matters if this is your first foreign market.
For anyone optimizing on cost, breadth, or automation, IBKR wins.
Trading Hours: The Part Americans Underestimate
The KRX regular session runs 9:00 AM – 3:30 PM Korea Standard Time, Monday through Friday (Korea has no daylight saving time). Translated:
| US Time Zone | KRX Session (US local time) |
|---|---|
| Eastern (EDT, summer) | 8:00 PM – 2:30 AM |
| Eastern (EST, winter) | 7:00 PM – 1:30 AM |
| Pacific (PDT, summer) | 5:00 PM – 11:30 PM |
| Pacific (PST, winter) | 4:00 PM – 10:30 PM |
Practical implications:
- West Coast investors have it easy — the Korean open is your late afternoon.
- East Coast investors: either trade the Korean open at 7–8 PM your time, or use Good-Till-Cancelled (GTC) limit orders placed during your day that rest until Seoul opens. This is how I’d run it — decide your price in the morning, set the order, check fills over coffee.
- Korean market holidays differ from US ones (Lunar New Year, Chuseok, etc.) — the KRX publishes its holiday calendar each year.
Taxes for US Investors: Simpler Than You’d Fear
This is general information, not tax advice — confirm with your CPA. But the framework is clean:
Dividends:
- Korea withholds 15% on dividends paid to US residents under the US–Korea tax treaty (versus the 25% default rate for non-treaty countries). Your broker applies the treaty rate automatically based on your W-9/account documentation.
- You’ll receive a Form 1042-S (or the amounts appear on your consolidated 1099) early in the year.
- Claim the Korean withholding as a Foreign Tax Credit on IRS Form 1116, which offsets the US tax on the same dividend income — you don’t get double-taxed, you just do a bit of paperwork.
Capital gains:
- For typical retail-sized positions in listed Korean stocks, non-resident US investors generally are not subject to Korean capital gains tax (the main exception is large shareholders — think 25%+ ownership stakes, which is not you).
- You pay US capital gains tax only, with the normal short-term (ordinary income) vs. long-term (0/15/20%) treatment.
Currency:
- KRW/USD movement is part of your return. Buy Samsung at ₩70,000, sell at ₩77,000 (+10%), but if the won weakened 5% against the dollar in that window, your USD return is roughly +5%. There’s no way around this in direct KRX investing — it is the trade. If you want Korea equity exposure without won exposure, that’s what currency-hedged ETFs are for.
Sell-side transaction tax:
- Korea charges a small securities transaction tax when you sell (not when you buy). It’s deducted automatically at execution — no filing required on your end.
First-Trade Checklist
Print this, or don’t — it’s short:
- ☐ Open IBKR account (or add Schwab Global Account to existing Schwab One) — 1–3 days
- ☐ IBKR only: enable South Korea (KRX) in Trading Permissions — same day
- ☐ Fund with USD
- ☐ Convert USD → KRW (convert ~5% more than your target position to cover fees and price movement)
- ☐ Look up the 6-digit KRX code for your stock
- ☐ Place a limit order (GTC if you’re asleep during Korean hours)
- ☐ After your first dividend: save the 1042-S, remember Form 1116 at tax time
The Bottom Line : How to Buy Korean Stocks Directly on the KRX
For a decade, “invest in Korea” meant settling for a thin menu of ADRs or a broad-market ETF. As of 2026, that’s over. A US investor with an evening free and a thousand dollars can own the exact same shares of the exact same companies that Seoul’s institutional money is buying — at institutional FX rates, through a broker regulated by the SEC.
The KRX is one of the ten largest equity markets in the world, home to the companies making the memory chips, ships, and weapons systems the rest of the decade will run on. It’s no longer hard to reach. It’s one permission checkbox away.
In upcoming posts, I’ll walk through a live first trade with screenshots, and break down the ADR-versus-local-shares price gap on Samsung Electronics in real time — the kind of thing you can only see clearly from Seoul.
