How to Invest in Korean Stocks Using Interactive Brokers: A Complete Step-by-Step Guide (2026)
How to Invest in Korean Stocks Using Interactive Brokers: A Complete Step-by-Step Guide (2026)
For years, investing in Korean stocks directly required opening a Korean brokerage account — a process that involved Korean language interfaces, local ID requirements, and wire transfers to Korean banks. The result: most global investors accessed Korea only through ETFs like EWY or FLKR, missing individual companies and the nuanced exposure that direct investing provides.
In 2026, that changed. Interactive Brokers opened direct access to the Korea Exchange — and then expanded it with Nextrade's extended-hours trading. If you have an IBKR account, you can now buy Samsung Electronics, SK Hynix, Hanwha Aerospace, HD Hyundai Electric, or any of 2,700+ Korean-listed securities as easily as buying a US stock.
This guide explains exactly how.

| Available To | US, Canada, UK, Europe, HK, Singapore, Australia | Same — NOT available to Korean residents |
| Currency | Korean Won (KRW) — converted from USD/GBP/EUR etc. | Korean Won (KRW) |
Why Use IBKR Instead of a Korea ETF or SKHY?
Before diving into the how-to, it helps to understand when direct KRX access makes sense versus simpler alternatives.
| Method | Best For | Limitation |
|---|---|---|
| Korea ETF (EWY/FLKR) | Broadest, simplest exposure — one trade covers Samsung, SK Hynix, Hyundai, and 80+ more | No control over individual stock weighting; includes stocks you may not want |
| SKHY (Nasdaq ADR) | Pure SK Hynix exposure via US brokerage — no currency conversion needed | Only one company; small Korea Discount vs Korean shares; limited to SK Hynix |
| IBKR Direct KRX | Any of 2,700+ Korean stocks directly; Samsung, Hanwha Aerospace, HD Hyundai Electric, LG Energy Solution, and more not available via Nasdaq ADR | Currency conversion required; Korean market hours; slightly more complex setup |
| Korean Brokerage Account | Full access including IPOs, rights offerings, Korean-language research | Complex setup; Korean language interface; wire transfer required |
IBKR direct KRX access is the right choice when you want exposure to specific Korean companies that are not available as US-listed ADRs — Samsung Electronics, Hanwha Aerospace, HD Hyundai Electric, LG Energy Solution, Hyosung Heavy Industries, Hanwha Ocean, and hundreds more.
Step-by-Step Guide: Setting Up IBKR for Korean Stocks
Step 1: Open an IBKR Account (If You Don't Have One)
If you don't already have an Interactive Brokers account, the process takes approximately 10–15 minutes online:
- Go to interactivebrokers.com and click "Open Account"
- Choose account type: Individual (most common), Joint, or IRA
- Complete the application — personal information, employment, financial background
- Submit government ID (passport or driver's license) for verification
- Account approval typically takes 1–3 business days
- Fund your account via bank wire or ACH transfer
Minimum deposit: IBKR has no minimum deposit requirement for standard accounts, though a funded account is required to place trades.
Step 2: Enable KRX Trading Permissions
(cite index="38-1">Existing Interactive Brokers clients can begin trading Korean equities immediately by enabling KRX market data and trading permissions in Client Portal.
Here is exactly how to do it:
- Log in to Client Portal at clientportal.ibkr.com
- Click your username (top right) → "Settings"
- Select "Account Settings"
- Scroll to "Trading Permissions" → click "Configure"
- Find "Asia" region → locate "Korea Exchange (KRX)"
- Check the box to enable → "Save"
- You may be prompted to acknowledge Korea-specific trading disclosures — accept these
- (cite index="38-1">Same-day account enablement is available. In most cases, KRX trading is enabled within minutes to hours
Step 3: Enable KRX Market Data
Trading permissions and market data subscriptions are separate. To see real-time Korean stock prices:
- In Client Portal: Settings → Market Data Subscriptions
- Find "Korea Stock Exchange Real-Time" or similar KRX data package
- Subscribe — monthly fee applies (typically $1–5/month depending on package)
- Without a market data subscription, you can still trade but will see delayed quotes
Alternative: If you prefer not to pay for market data, you can check Korean stock prices on free resources like investing.com, then place orders through IBKR with limit orders to control your execution price.
Step 4: Convert Currency (USD → KRW)
Korean stocks trade in Korean Won (KRW). Before placing your first order, you need to convert some of your USD (or other base currency) to KRW.
Two methods in IBKR:
Method A — Automatic conversion (simplest): IBKR can automatically convert currency at the time of trade. When you place a buy order for a Korean stock, IBKR will convert the required amount from your base currency at current market rates plus the FX commission (as low as 0.20 basis points — approximately 0.002%). This is the easiest approach for occasional traders.
Method B — Manual conversion via Forex (more control):
- In Trader Workstation or Client Portal: go to "Trade" → "Forex Trading"
- Select currency pair: USD/KRW
- Enter the amount of USD you want to convert to KRW
- Place a market or limit order
- Converted KRW appears in your account balance, ready for Korean stock purchases
(cite index="38-1">FX conversion commissions are as low as 0.20 basis points (0.0020%) of the trade value. On a $10,000 conversion, that is approximately $0.20 — extremely competitive versus the spreads charged by most retail forex services or Korean wire transfers.
Step 5: Find Korean Stock Tickers
Korean stocks use a 6-digit ticker system — different from the alphabetic tickers used in US markets. Here are the key Korean tickers you will likely search for:
| Company | Korean Ticker | Sector | IBKR Search Tip |
|---|---|---|---|
| Samsung Electronics | 005930 | Semiconductors / Electronics | Search "Samsung" or "005930 KRX" |
| SK Hynix | 000660 | HBM / Memory Chips | Search "SK Hynix" or "000660 KRX" |
| Hyundai Motor | 005380 | Automotive / Physical AI | Search "Hyundai Motor" or "005380 KRX" |
| Hanwha Aerospace | 012450 | Defense | Search "Hanwha Aerospace" or "012450 KRX" |
| HD Hyundai Electric | 267260 | Power Infrastructure | Search "HD Hyundai Electric" or "267260 KRX" |
| LG Energy Solution | 373220 | EV Batteries | Search "LG Energy" or "373220 KRX" |
| Samsung Biologics | 207940 | Biopharma CDMO | Search "Samsung Biologics" or "207940 KRX" |
| LS Electric | 010120 | Power Grid / AI Infrastructure | Search "LS Electric" or "010120 KRX" |
| Hanwha Ocean | 042660 | Naval Shipbuilding / Defense | Search "Hanwha Ocean" or "042660 KRX" |
| Kia | 000270 | Automotive / EV | Search "Kia" or "000270 KRX" |
In IBKR's search bar: Type the company name in English. IBKR will return results including the KRX-listed security. Make sure to select the one with exchange "KRX" — not any OTC or pink sheet equivalent that may also appear.
Step 6: Place Your First Korean Stock Order
Once you have KRX permissions enabled and KRW in your account (or auto-conversion set up), placing a Korean stock order works the same as any other IBKR order:
- Search for the company in Trader Workstation (TWS) or the Client Portal mobile app
- Verify the exchange shows "KRX" in the order ticket
- Select order type: Limit order recommended for Korean stocks due to the time zone difference — set a limit price you are comfortable with rather than a market order that executes while you sleep
- Enter quantity (number of shares — Korean stocks are priced in KRW per share, often in the hundreds of thousands of KRW range)
- Set time-in-force: Day (expires if not filled during Korean trading hours) or GTC (Good Till Cancelled — remains active across multiple trading days)
- Review and submit
Step 7: Nextrade Extended Hours Trading
A major advantage of IBKR's June 30, 2026 Nextrade addition is extended Korean trading hours. (cite index="42-1">Nextrade offers access to approximately 650 securities from the KOSPI and KOSDAQ markets, competitive fees, and an extended 12-hour trading window, running from 8:00 AM to 8:00 PM KST across three sessions.
This means US-based investors can now trade select Korean stocks during US daytime hours:
| Session | KST Hours | US Eastern Time | US Pacific Time |
|---|---|---|---|
| Nextrade Pre-Market | 8:00 AM – 9:00 AM KST | Previous evening 7:00 PM – 8:00 PM ET | Previous evening 4:00 PM – 5:00 PM PT |
| KRX Main Session | 9:00 AM – 3:30 PM KST | 8:00 PM – 2:30 AM ET | 5:00 PM – 11:30 PM PT |
| Nextrade Post-Market | 3:30 PM – 8:00 PM KST | 2:30 AM – 7:00 AM ET | 11:30 PM – 4:00 AM PT |
(cite index="42-1">IB SmartRouting™ is enabled across both KRX and Nextrade, automatically routing orders to the venue offering the best price. You don't need to choose between KRX and Nextrade manually — IBKR's SmartRouting handles this automatically.
Costs and Fees
Understanding the full cost of Korean stock investing through IBKR helps set realistic expectations:
| Cost Item | IBKR Amount | Notes |
|---|---|---|
| Trading Commission (KRX) | 0.08% of trade value (min. 8,000 KRW) | Typical for Korean market — similar to Korean brokerages |
| FX Conversion | As low as 0.20 bps (0.0020%) | On $10,000 trade: ~$0.20. Very competitive |
| Market Data | $1–5/month (KRX real-time) | Optional — delayed data is free |
| Korean Securities Transaction Tax | 0.18% on KOSPI sells (IBKR collects) | Government tax — applies to all Korean stock sales |
| Account Maintenance | No monthly fee (IBKR Pro with activity) | Inactivity fee may apply for low-activity accounts |
| Dividend Withholding Tax | 22% withheld at source (Korea) | May be partially recoverable depending on your country's tax treaty with Korea |
The Korean Securities Transaction Tax (STT) of 0.18% applies to sales on the KOSPI — this is a government-imposed tax, not an IBKR fee. It is collected automatically by IBKR on your behalf. Factor this into your cost basis when evaluating round-trip trading costs.
What Korean Stocks to Consider — The IBKR Advantage
The real power of IBKR KRX access is the ability to buy companies that are not available as US-listed securities. Here are the investment themes and specific stocks that make direct KRX access most valuable:
AI Memory (not available via ETF weighting you control):
Samsung Electronics (005930) — buy more than EWY's ~23% weighting allows
SK Hynix (000660) — if you prefer the Korean listing to SKHY, or want to avoid ADR discount
Defense (not available as US ADRs):
Hanwha Aerospace (012450) — the world's fastest-growing defense exporter
LIG Nex1 (079550) — Cheongung-II air defense, missiles, electronic warfare
Hyundai Rotem (064350) — K2 Black Panther tank manufacturer
Korea Aerospace Industries / KAI (047810) — FA-50 fighter jet
Power Infrastructure (not available as US ADRs):
HD Hyundai Electric (267260) — AI data center transformers, record order backlog
LS Electric (010120) — power grid, AWS and Bloom Energy contracts
Hyosung Heavy Industries (298040) — transformers and power equipment
EV Batteries (not available as US ADRs):
LG Energy Solution (373220) — Korea's largest EV battery maker, 9% global share
Samsung SDI (006400) — EV batteries and energy storage
Physical AI / Robotics:
Hyundai Motor (005380) — Boston Dynamics, NVIDIA partnership
Kia (000270) — EV leadership, typically trades at discount to Hyundai Motor
IBKR vs Korea ETF vs SKHY: Which Is Right for You?
| Investor Profile | Recommended Approach | Why |
|---|---|---|
| First-time Korean equity investor | EWY or FLKR ETF | Simplest — no currency conversion, no Korean tickers, instant diversification |
| Want pure SK Hynix exposure quickly | SKHY on Nasdaq | No IBKR KRX setup needed; USD-denominated; trades during US hours |
| Want Samsung directly (not ETF blend) | IBKR KRX (005930) | Samsung has no Nasdaq ADR — KRX is the only direct route |
| Want Korean defense stocks | IBKR KRX | Hanwha Aerospace, LIG Nex1, KAI — none available as US ADRs |
| Want Korean power infrastructure | IBKR KRX | HD Hyundai Electric, LS Electric — none available as US ADRs |
| Want LG Energy Solution | IBKR KRX (373220) | No US ADR or GDR — KRX only for foreign investors |
Key Risks and Practical Considerations
- Currency risk: Your Korean stock investments are denominated in KRW. A weakening won reduces USD returns even if the stock price rises in KRW terms. Monitor USD/KRW — a rate above 1,400 KRW/USD represents meaningful currency headwind for USD-based investors.
- Time zone trading: Korean markets trade during Asian hours — while most US investors are asleep. Use limit orders with GTC (Good Till Cancelled) to control your execution price rather than leaving market orders that execute at unknown prices overnight.
- Share price denomination: Korean shares are not fractional and can be expensive per share. Samsung at ~280,000 KRW (~$200/share) is accessible. SK Hynix at ~1,850,000 KRW (~$1,300/share) requires larger capital per share. Plan position sizing accordingly.
- Dividend withholding: Korea withholds 22% on dividends paid to foreign investors. Depending on your country's tax treaty with Korea, some or all of this may be creditable against your domestic tax liability. Consult a tax advisor.
- Market volatility: 2026 has demonstrated that Korean markets can be extraordinarily volatile — the KOSPI crashed 40% from its June high to its July low. Direct stock investing amplifies this volatility versus diversified ETF exposure. Size positions appropriately.
Frequently Asked Questions
Do I need a minimum account balance to trade Korean stocks through IBKR?
IBKR has no minimum deposit requirement, but you need sufficient funds to buy at least one share of your target Korean stock (and to cover the currency conversion and transaction tax). Given that one share of SK Hynix costs approximately 1,850,000 KRW (~$1,300 USD), you need at least that amount plus trading costs in your account for that particular stock.
Can I hold Korean stocks in an IRA through IBKR?
Yes — IBKR allows international stock trading including Korean stocks in IRA accounts (Traditional, Roth, SEP IRA). This makes KRX access through IBKR particularly attractive for US investors who want tax-advantaged Korean equity exposure. Note that the dividend withholding tax still applies within an IRA.
Is IBKR safe for holding Korean stocks?
Interactive Brokers is one of the world's largest electronic brokers, publicly listed on Nasdaq (IBKR), with over $100 billion in client assets. It is regulated by the SEC and FINRA in the US, and equivalent regulators in all major markets where it operates. Your Korean stocks held at IBKR receive the same regulatory protections as US stocks held at IBKR.
What is the difference between buying SK Hynix on KRX vs SKHY on Nasdaq?
SKHY (Nasdaq ADR) represents 1/10th of one Korean-listed SK Hynix share, denominated in USD, tradeable during US market hours without currency conversion. KRX-listed SK Hynix (000660) represents one full Korean share, denominated in KRW, tradeable during Korean market hours. SKHY sometimes trades at a slight discount to the Korean equivalent — this "ADR discount" may close over time as US investor familiarity with the ADR grows. For most US investors, SKHY is simpler. For investors who want to avoid any ADR discount and prefer full Korean share economics, the KRX listing via IBKR is the alternative.
