Best Brokers for US Investors to Trade Asian Stocks

US investors can access Asian stock markets - Hong Kong, Japan, Singapore, and beyond - through international brokers, with Interactive Brokers (IBKR) offering the widest coverage. For the biggest Asian names, US-listed ADRs are a simpler alternative. This guide compares brokers market by market, with a cross-border cost calculator so you know what to expect on fees.

Key Takeaways
  • -IBKR has the widest Asian market access: HK (HKEX), Japan (TSE), Singapore (SGX), South Korea (KRX), Taiwan (TWSE) - all in one account.
  • -ADRs (American Depositary Receipts) are the no-new-account-needed shortcut for big Asian names: Toyota (TM), Sony (SONY), Alibaba (BABA), Baidu (BIDU). Available at any US broker.
  • -Expect FX conversion costs plus local market charges: HK stamp duty 0.10% per side; Japan: no stamp duty; Singapore: 0.20% stamp duty on purchases.
  • -Japan dividends: 15.315% Japanese withholding tax applies, but the US-Japan tax treaty allows a foreign tax credit. HK dividends: no withholding tax, but ordinary income in the US (no US-HK treaty).
  • -Charles Schwab International and Futu US: only offer HK access among major Asian markets for US retail investors (plus US-listed ADRs). No direct Japan/Singapore/Korea.

Cost verdict for your inputs:

ADR route is cheaper by $55.60 per year for your inputs. The FX spread at IBKR (Interactive Brokers) makes HK-direct more expensive at this trade size. For more frequent or larger trades, HK-direct with IBKR typically wins on cost.

Caveat: ADR coverage is limited to ~30-40 large HK-listed companies. For Tencent (0700.HK), BYD (1211.HK), CNOOC (0883.HK) and the full HKEX universe of 2,600+ stocks, only the HK-direct route provides access.

Assumptions: round-trip = 1 buy + 1 sell of equal size; HK stamp duty 0.10% per side (Aug 2023 rate); HKEX levies 0.008% per side; ADR custody $0.02/share/year; ADR spread 0.10% per side. FX spreads are approximations based on published broker fee schedules. This tool is for illustration only and does not constitute financial advice.

Broker-by-broker breakdown for US investors buying Asian stocks

When I tested IBKR's HK order routing for 9988.HK, my limit order placed at 11pm ET was filled within the first 10 minutes of the next HKEX morning session. For Japanese stocks, IBKR routed a Toyota (7203.T) order to TSE with the same speed. The account setup is the same for all Asian markets - no separate sub-accounts needed. Here is what each broker offers.

Interactive Brokers (IBKR)

Best overall - widest Asian market access
Pros
  • +Direct access: HK (HKEX), Japan (TSE), Singapore (SGX), Korea (KRX), Taiwan (TWSE), India, Australia - all in one account
  • +Best FX rates for retail: ~0.02% USD/HKD, ~0.02% USD/JPY spread
  • +$2.50 commission per HK trade; $0 custody fee
  • +$0 minimum account (IBKR Lite); IBKR Pro has $100K threshold for free market data
Cons
  • -Interface complexity: Trader Workstation (TWS) has a steep learning curve
  • -$10/month inactivity fee if balance under $100K and no trades (waived with regular activity)
  • -Japan market data subscription may add ~$1.50/month
The clear choice for any US investor who wants genuine direct access to more than one Asian market. No other retail broker comes close on breadth.

Charles Schwab International

HK access only; $0 commission; $25K minimum
Pros
  • +$0 commission per HK trade
  • +Strong brand and customer service, familiar for existing Schwab clients
  • +Good for long-term holders of a small number of HK names
Cons
  • -FX spread ~0.75-1% on HKD - far higher than IBKR for active traders
  • -$25,000 minimum for international trading account
  • -No direct Japan, Singapore, or Korea access
The $0 commission sounds attractive but the 0.75-1% HKD FX spread quickly exceeds IBKR's total cost for trades above ~$1,000. For Japan or Singapore, look elsewhere.

Futu / moomoo (US account)

HK + US; easy mobile app; HK access only in Asia
Pros
  • +$0.99 flat commission per HK trade; ~0.3% FX spread on HKD
  • +Clean, user-friendly mobile app; HK + US stocks + some China A-shares
  • +Good market data for HK stocks within the app
Cons
  • -Futu is a Chinese-controlled company - some US investors may have security or regulatory concerns
  • -No direct Japan, Singapore, or Korea market access
  • -Limited to HK for direct Asian equity access beyond US-listed ADRs
A solid choice if your Asian equity focus is Hong Kong and you want a cleaner app experience than IBKR TWS. For broader Asian market access, IBKR is necessary.

Tiger Brokers

HK + US + Singapore; good for Asia-focused US investors
Pros
  • +Provides access to HK (HKEX), US, and Singapore (SGX) in one account for some US account types
  • +User-friendly mobile-first interface; competitive commission rates
Cons
  • -Tiger is also a Chinese-controlled company (UP Fintech Holding) - similar regulatory concerns as Futu
  • -No direct Japan or Korea market access for US retail investors
  • -Smaller US market presence than IBKR or Schwab; customer service can be slower
A reasonable option if you want HK + Singapore in one app, but check current US availability as the offering can change. IBKR covers more Asian markets at lower FX cost.

The ADR shortcut: major Asian stocks you can buy at any US broker

If you want exposure to a handful of well-known Asian companies without opening an international brokerage account, US-listed ADRs are the path of least resistance. You buy them in USD, during US market hours, through any US broker - same as buying Apple or Amazon stock. The trade-off is limited coverage (only the largest Asian names have US ADRs) and a depositary custody fee of roughly $0.01-0.05 per share per year.

Note: OTC-listed ADRs (like TCEHY for Tencent, BYDDY for BYD) typically have lower volume and wider spreads than NYSE/NASDAQ-listed ADRs. For Tencent and BYD, buying the HK-listed shares directly via IBKR generally gives better price discovery and lower effective spread. NYSE/NASDAQ-listed ADRs (BABA, TM, SONY, BIDU) are generally more liquid.
