Money is just another good traded in markets

The best way to understand exchange rates is to reinvent the way you look at money. Take for example an apple farmer who takes a truck load of apples to the market every day. Most of us would immediately assume that he is going to the market to sell apples but let’s turn this around for a minute and say that instead he is going to the market to buy rands. And is this not what all of us as working folk do; we take our skills or resources to the market in order to exchange them for, or buy, much needed money that we can use. Source
