The dollar is the reserve currency of the world. This means that most central banks hold the dollar as part of their foreign exchange reserves. Part of the reason for this is the strength of the American economy, the democratic nature of the country, and the perceived stability.
The dollar index is the most widely used measure of the dollar strength. It measures it against the most liquid currencies. The weightings are shown in the table below.
To traders, understanding the price movements of the dollar index is very important. Part of this is that most commodities are priced in dollars. Therefore, a major strength in the dollar makes them more expensive.
As shown below, the dollar index started a major rally in mid 90s and peaked at $120 in 2002. It then underwent a major correction that brought it to a low of $71 in 2008 during the financial crisis.
