Investopedia explains Currency ETF
Currency ETFs are widely used by investors who wish to gain exposure to the foreign exchange market and would prefer not to enter the futures or forex markets. With the growing popularity of ETFs, investors have found it very easy and relatively inexpensive to trade currency ETFs in order to take advantage of fluctuations between currencies. Currency ETFs can be purchased to track most international currencies including the U.S. and Canadian dollars, the Euro, British pound and Japanese yen.
