Currency ETFs have done an excellent job of providing access to a market that was difficult for retail investors to access as recently as a decade ago. In the past, an investor needed a separate account to trade currencies and high minimums were involved. Today, an individual investor can gain exposure to, say, the Swiss franc with less than $100 and a brokerage account.

Since the first currency ETF was launched in 2005, the sector has grown to include 24 currency funds.
