A nation’s currency rate rises and falls against other currencies from second to second in the Forex Markets. If the currency is in a fixed exchange rate system, it is referred to as devaluation and revaluation. As the terms imply, devaluation is a drop in the currency value and revaluation is a rise in the currency’s value. These fluctuations are officially sanctioned changes that are mandated by governments or central banks. In the global economy, though, more and more nations are moving away from a fixed exchange rate system in favor of a floating exchange rate system.
