Introduction to Forex - Major Currencies

The U.S. Dollar.

The United States dollar is the world's main currency – an universal measure to evaluate any other currency traded on Forex. All currencies are generally quoted in U.S. dollar terms. Under conditions of international economic and political unrest, the U.S. dollar is the main safe-haven currency, which was proven particularly well during the Southeast Asian crisis of 1997-1998.

As it was indicated, the U.S. dollar became the leading currency toward the end of the Second World War along the Breton Woods Accord, as the other currencies were virtually pegged against it. The introduction of the euro in 1999 reduced the dollar's importance only marginally.

The other major currencies traded against the U.S. dollar are the euro, Japanese yen, British pound, and Swiss franc.
