The foreign exchange market (forex) is a market where world currencies are traded 24 hours a day. For some, it's simply a mechanism for changing one currency into another, such as multinational corporations doing business in various countries. However, the market is also occupied by traders who bet on movements of currencies relative to each other.
- Because of their liquidity, trading currencies is exceptionally popular.
- Currency traders are not bound by the margin limits imposed by the Securities and Exchange Commission (SEC) on securities traders. This means those traders can make heavily leveraged trades.
- The most popular way to invest in currencies is by trading currencies in the forex, but investors can buy ETFs, invest in corporations, and others.
- Like all investments, investing in currencies involves risk, especially during volatile economic times.
Standard Forex Trading Account
You can open an account with a forex broker and trade currencies from around the world. There are several differences in how this market operates when compared to the U.S. stock exchanges:
- Currencies are traded in pairs - you are betting one will go up (long) and the other will go down (short).
- No regulated currency exchange and no central clearinghouse for trades.
- No uptick rule for taking short positions.
- No upper limit in the size of your position.
- Currency dealers generally make money on the bid-ask spread, rather than charging commissions.
CDs & Savings Accounts
TIAA Bank offers a WorldCurrency certificate of deposit (CD) that earns interest at local rates in specific countries, and a basket CD that includes a mix of various currencies. It also offers a foreign currency account that functions like a money market account and allows the transfer of money between major currencies.
The CDs are subject to exchange rate fluctuations but feature a higher interest rate than dollar-denominated CDs. When the CD matures, you will get back fewer dollars than you invested if the dollar strengthened against the foreign currency. FDIC insurance protects you against bank insolvency, but not the currency risk.
Foreign Bond Funds
There are mutual funds that invest in foreign government bonds, which earn interest denominated in the foreign currency. If the foreign currency goes up in value relative to your local currency, the earned interest increases when converted back to local currency.
Many stockholders indirectly participate in the foreign currency markets through their ownership in companies that do significant business in foreign countries. Some of the better known American companies with overseas exposure are Coca-Cola, McDonald's, IBM and Walmart.
The revenues and profits derived from overseas operations are boosted if the foreign currency appreciates versus the dollar. This is because those revenues are converted back into dollars for financial reporting purposes, and a stronger foreign currency will yield more dollars in exchange.

ETFs and ETNs
Exchange-traded funds (ETFs) and exchange-traded notes (ETNs) are traded like stocks and can be a way to invest in currencies without needing to trade the forex. With a standard investing account with most brokerages, investors can buy access to currency ETFs such as UUP, the Invesco DB US Dollar Index Bullish Fund or EUO, the ProShares UltraShort Euro.
ETNs are more similar to corporate bonds than a collection of stocks, but they tend to have a similar exposure to the currency market as ETFs. On the same exchange, you would trade ETFs, common currency ETNs such as GBB, the iPath® GBP/USD Exchange Rate ETN.
The Bottom Line
One advantage of the currency market is that it's theoretically a level playing field. Currencies are impacted by world events around the clock, and the internet and wireless communications provide almost instant access to even small investors. Currencies provide some measure of diversification for people who invest primarily in U.S. securities.
