How to Invest in International Stocks from the USA Using Interactive Brokers or Schwab
While the United States currently boasts the largest, most liquid, and most dynamic stock market in the history of the world, it represents only a fraction of the total global economy. By restricting your investment portfolio solely to American companies, you are explicitly ignoring massive demographic shifts, technological innovations, and rapid growth opportunities occurring in emerging markets and established international economic powerhouses. Learning how to securely and efficiently invest in international stocks from the USA is a critical step for achieving true, global portfolio diversification and protecting your wealth against a potential long-term decline in the US dollar or American economic dominance.
Historically, buying foreign stocks was a prohibitively complex, highly opaque, and wildly expensive endeavor reserved exclusively for institutional investors and ultra-high-net-worth individuals. Retail investors had to deal with terrible currency exchange rates, predatory foreign brokerage fees, and massive regulatory hurdles. Today, modern financial technology and globalized brokerages have completely democratized access to the world’s markets. This massive, comprehensive guide will meticulously explain the different methods available to everyday US investors and provide a step-by-step, data-driven look at using two of the absolute best platforms for international trading: Interactive Brokers and Charles Schwab.
Why Invest Internationally? The Data-Driven Case
The primary, undeniable reason to look beyond US borders is diversification. The fundamental law of investing states that diversification is the only “free lunch” in finance. The US stock market and international stock markets do not always move in perfect tandem. There are entire decades where US stocks significantly outperform international stocks, and there are decades where the exact reverse is true. By holding a calculated, strategic mix of both, you mathematically smooth out the volatility of your portfolio and protect yourself against a prolonged, devastating downturn in any single country’s economy.
| Decade | US Stock Market Performance | International Stock Market Performance | The Winner |
|---|---|---|---|
| 1970s | +77% | +151% | International |
| 1980s | +399% | +578% | International |
| 1990s | +432% | +154% | USA |
| 2000s (The Lost Decade) | -9% | +12% | International |
| 2010s | +256% | +46% | USA |
As the table clearly demonstrates, betting exclusively on the USA every single decade is a mathematically flawed strategy. Furthermore, many of the world’s absolute most dominant, monopolistic companies in critical sectors like luxury goods (LVMH), advanced semiconductor manufacturing (TSMC), and automotive engineering (Toyota) are based completely outside the USA. If you want direct exposure to these specific, world-beating industry leaders, you must be willing to invest internationally.
Method 1: American Depositary Receipts (ADRs)
The absolute easiest, most friction-free way for a standard US retail investor to buy a piece of an international stock is through a financial instrument known as an American Depositary Receipt (ADR). An ADR is a legal certificate issued by a major US bank that represents a specific number of shares (or a fraction of a share) in a foreign stock. These certificates trade on standard, regulated US exchanges (like the New York Stock Exchange or the NASDAQ) just like regular American stocks.
The beauty of the ADR is its simplicity. They are priced directly in US dollars, they pay their dividends directly in US dollars, and they clear through standard US settlement processes. For example, if you want to buy shares of Sony or Alibaba, you do not need to convert your money to Japanese Yen or Chinese Yuan, nor do you need to open a complex foreign brokerage account. You simply log into your standard US brokerage account and execute a buy order for the Sony ADR. It is a seamless process. The only minor downsides are that not every single foreign company offers an ADR, and the banks that issue them sometimes charge a very small, barely noticeable custody fee (usually a few cents per share annually) that is automatically deducted from your dividends.
Method 2: International Mutual Funds and ETFs
If you prefer a hands-off, passive, and highly optimized approach, the most efficient way to gain sweeping international exposure is through mutual funds or Exchange Traded Funds (ETFs). An international index fund will instantly give you fractional ownership in literally thousands of companies spread across dozens of countries with a single, low-cost purchase.
You can choose broad “Total International” funds that cover the entire globe outside the US (capturing both developed and emerging markets), or you can select highly specific regional funds, such as an “Emerging Markets ETF” (focusing on fast-growing economies like India and Brazil) or a “European Dividend Fund” (focusing on mature, dividend-paying companies in Germany, France, and the UK). This method requires zero effort on your part to research individual foreign companies, making it the preferred, mathematically optimal choice for most passive investors. We discuss this exact strategy further in our deep-dive article on Index Funds in the USA.
Method 3: Direct Trading on Foreign Exchanges
For advanced, aggressive investors who want to buy specific, smaller foreign companies that do not offer ADRs, direct trading is absolutely required. This complex process involves mathematically converting your US dollars into a foreign currency and executing a live trade directly on a foreign exchange (such as the London Stock Exchange, the Tokyo Stock Exchange, or the Frankfurt Stock Exchange). This is where your specific choice of brokerage becomes the difference between a profitable trade and getting destroyed by hidden fees.
The Professional Choice: Using Interactive Brokers (IBKR)
Interactive Brokers (IBKR) is widely considered by professionals to be the absolute gold standard for international, multi-currency trading. They offer direct, high-speed access to over 150 unique markets in dozens of countries from a single, unified, highly advanced platform. Their currency conversion rates are institutional-grade, meaning you will pay a fraction of a percent over the true spot rate. You will not lose a massive, predatory percentage of your capital just swapping your dollars for euros.
To trade internationally on IBKR, you must first formally request trading permissions for the specific countries you are interested in via your account settings. Once approved by their compliance team, you can simply type in the foreign ticker symbol. The highly advanced platform will prompt you to either use your existing foreign currency balance or it will automatically convert your US dollars at the real-time spot rate to fund the trade seamlessly.
The Premium Retail Choice: Using Charles Schwab
Charles Schwab is an excellent, highly reputable option for investors who want a more traditional, customer-service-oriented retail brokerage experience but still desire robust, direct international access. Schwab offers a specialized, premium service known as the Schwab Global Account. Once activated alongside your standard brokerage account, this global account allows you to trade directly online in 12 of the most popular, liquid foreign markets using their native local currencies.
While Schwab’s currency conversion fees are slightly higher than Interactive Brokers, their platform is generally considered much more user-friendly and approachable for beginners who might be intimidated by IBKR’s complex interface. Schwab also provides robust, institutional-grade international research reports, which is absolutely invaluable when analyzing foreign companies that do not adhere to standard US accounting principles (GAAP).
Conclusion
Adding international stocks to your portfolio is a proven, mathematically sound strategy for reducing catastrophic risk and capturing global growth as the economic power shifts around the world. Whether you choose the absolute simplicity of ADRs and broad-market ETFs or you demand the direct, granular access provided by Interactive Brokers and Charles Schwab, you now have the exact tools necessary to build a truly global, resilient portfolio. As always, ensure your international investments align perfectly with your overall asset allocation strategy.
