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.
- -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.

HK-Direct Route
US-ADR Route
Lower costADR 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.

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.
